[Asus  Eee Pad Transformer Prime] phflorian:
the thing is I can't manage to root explorer, as soon as I get to the lockscreen, a few seconds later it will go bootlooping again.

I've been trying to use adb, and I actually tried to do:

adb remount

but it returned:

failed to copy 'build.prop' to '/system/build.prop': Read-only file system

what would happen if I do this:

adb shell sysrw

adb push build.prop /system

adb shell sysro

?
[Asus  Eee Pad Transformer Prime] Skullmonkey:
I haven't done ADB in so long that I forgot almost everything lol.

I think

adb mount /system

should work.

My prime is in a bricked state right now (after reading an email o.0. No mods and still locked. About to call ASUS.) so I can't test it out atm.
[Asus  Eee Pad Transformer Prime] demandarin:
Good Idea

good to hear. after running this for a while, let us know if you seeing better battery life. it should since wifi scan is lowered & the deep sleep mode is better with power collapse=1. with CPU spy, I'm noticing my prime hits deep sleep faster and longer. hardly drains at all with this new deep sleep optimization.

Yes, this would be the best scenario. ill add this and the one below to the OP.

good info..ill add this.
[Asus  Eee Pad Transformer Prime] phflorian:
tried it just now, and cmd gave me a list of adb functions instead lol

---------- Post added at 09:53 PM ---------- Previous post was at 09:41 PM ----------

got it fixed just now! :)

demandarin, do you mind putting these onto the OP:

adb shell

$ su

# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

# chmod 777 /system (Or any subdirectory you want to push to inside system)

# exit

$ exit

adb push build.prop /system

so that anyone who might run into the same problem as mine will know how to push their original build.prop.
[Asus  Eee Pad Transformer Prime] demandarin:
gotcha. glad to hear you was able to push original build prop back in. Ill add this info now. thanks.

as to your other post, you not supposed to notice any changes until after the modded build.prop is put in, permissions properly set and rebooted. not before you reboot. not sure what caused your boot loop. Are you on US .21 or another region version?
[Asus  Eee Pad Transformer Prime] Danny-B-:
# mount -o rw,remount /system

Once you are done making changes, you should remount with the original readonly.

# mount -o ro,remount /system

-from google
[Asus  Eee Pad Transformer Prime] demandarin:
if original is pushed back, couldn't he just use root explorer to mount it back as Readonly? so he got his original file pushed back but forgot to put it back to read only, like it was originally.

how this this command supposed to look completely with what you said? Can you post it? so i can copy & add it to the op. the device could be susceptible to others if left mounted as RW and you don't realize it.
[Asus  Eee Pad Transformer Prime] phflorian:
I am on TW.21 version.

I edited my build.prop again just now, but I used text editor in root explorer. Rebooted, and my prime is working fine now.

and btw thanks to Skullmonkey for replying to my post, you gave me help and relieved my panic a bit lol :D
[Asus  Eee Pad Transformer Prime] buxtahuda:
An update! lol

Battery life is definitely affected! I haven't seen drainage this small since .11, I only lost 1% over an 8 hour period; I accidentally had BT on for the last three hours and have only drained an extra 3% because of it. Fantastic!
[Asus  Eee Pad Transformer Prime] Danny-B-:
those commands just mount the system folder in a a RW state so you can then push the modified/ original build.prob to the device.

after you push the the ( ie "ADB push c:\build.prop /system/" ) You want to re-enable "RO" read only.

Will list comand when i get home.
[Asus  Eee Pad Transformer Prime] demandarin:
Damn! lmfao. that reduced wifi scan interval and better deep sleep(power collaspse=1) really makes a difference. I noticed better battery life also.

thanks for the feedback!
[Asus  Eee Pad Transformer Prime] dagrim1:
Cool, succesfully applied this to WSG beta v0.0.6 (only cleared some of the empty lines in the file)... Too early to tell about any differences but wanted to tell it can be used with WSG 0.0.6 :)
[Asus  Eee Pad Transformer Prime] DamBadz:
Hey guy i edit in side this (us to ww)and copy it to sytem am wrong? Sorry for ma bad english thx
[Asus  Eee Pad Transformer Prime] buxtahuda:
That is correct. Be sure to use a proper tool like Notepad++ to edit the file on your computer, or an app like build.prop Editor to edit it directly from your Prime.

Be careful! The easiest way would be to get the US build.prop and your WW build.prop both on your computer and to use Notepad++ to move the extra lines from the US to your WW. This should help cut down on any user error and bootloops/bricks.
[Asus  Eee Pad Transformer Prime] demandarin:
OP is updated with great info on some examples of what each of the added tweaks lines in modded build.prop does.
[Asus  Eee Pad Transformer Prime] DamBadz:
Many THX! Ar..where I can get original ww prop? That is the one I have now that right?and I just copy it?
[Asus  Eee Pad Transformer Prime] buxtahuda:
That's right, assuming you haven't made any other changes then the build.prop that is already located in /system/ should be stock WW.
[Asus  Eee Pad Transformer Prime] DamBadz:
OK one more thing in your custom build prop I got to Chang all the us text to ww right? Thx for the help^^
[Asus  Eee Pad Transformer Prime] Diamondback:
I moved the thread to development because it rather belongs to dev stuff than to general :)
[Asus  Eee Pad Transformer Prime] Gage_Hero:
Spot on Rom/Kernel/Tweak page?

Hey guys,

Should see if you can get the thread linked to the Rom Kernel and tweak page, people that only look there might not look further down for the thread :)
[Asus  Eee Pad Transformer Prime] demandarin:
Developement section now ;) moving on up..lol

ill pm that OP of the thread and see if he can do it.
[Asus  Eee Pad Transformer Prime] maxfac1234:
The best thing to do is to pull/check your build.prop in /system and compare to the build.prop posted by demandarin side by side.

In the mod build.prop, more lines are added to it (mostly in the last third of that file). Just change the similar entries (beginning two-third) to reflect your original build.prop.
[Asus  Eee Pad Transformer Prime] Lock-N-Load:
Okay.. used it the last 12 hours and I honestly, notice no real difference in speed or battery. Just going on perception, but I perceive no real change I could report.

I might try to do some more scientific testing on battery like what I did back when we were having serious battery drain before .21 and see if there is an improvement there.

But again, just on "perception" I don't "feel" any change.
[Asus  Eee Pad Transformer Prime] micaman:
You can thank me for that ;)...you should know better than to start a [MOD] thread in the General Section :)
[Asus  Eee Pad Transformer Prime] demandarin:
thanks buddy

thanks. but I was going off their rule of " if you didnt create it, then it doesn't belong in developement" I originally was going to put it in here but was unsure. so i figured if I put it in general, that'll be on the safe side and mods would move it to DEV. If they saw fit.

so you reported me huh? lmao. just kidding...thanks...it is now where it belongs. I might celebrate tonight. my first DEV thread..lol

I ran out of thanks...ill hit you up once mines reset. ;)
[Asus  Eee Pad Transformer Prime] snapdoodle:
Feels snappier to me have not checked battery yet.
[Asus  Eee Pad Transformer Prime] demandarin:
looking forward to results of your test. Me and others are experiencing real world results with this. This mod enables a way better deep sleep mode. it goes to deep sleep faster and stays there longer battery hardly drains at all during deep sleep. it puts the prime in a coma now..lol. that along with reduced wifi interval scan & you should be seeing the results.

Then with all the other added tweak lines, your overall responsiveness of prime should be faster n more fluid. especially with swiping homescreens, app drawer, scrolling in browsers, etc...

My games don't crash anymore also. I haven't had any kind of crash, freeze, or lag anywhere since doing this mod a day or so ago.

maybe try another reboot to make sure the tweaks stick. I've seen some people recommend that for certain build.prop tweaks.

you can use CPU spy to see your prime hitting deep sleep longer.
[Asus  Eee Pad Transformer Prime] biggem001:
me too. and i use my tfp heavily at work and school. installed build.prop minutes after OP posted and, really, i call placebo effect.

No real difference as of yet (2nd day now). Battery still was lost at normal rate. same normal hiccups and speed.
[Asus  Eee Pad Transformer Prime] demandarin:
well I did add to my OP a list proving what most of the added lines do. check it out. you can check out the OG developer link also and see people having good results there also.
[Asus  Eee Pad Transformer Prime] Deathmo:
Could some one of the people, who already edit there WW build.prop., that works fine for them, load up for us terminal noobs, or lazy guys? :D

Please. :)
[Asus  Eee Pad Transformer Prime] Mekrel:
Personally, I can't tell of any difference but for anyone interested, I've made a WW .21 version which is attached to this post.
[Asus  Eee Pad Transformer Prime] buxtahuda:
I'm sure plenty will appreciate it.

Believe me, I definitely do and take all this with a grain of salt, I'm willing to admit it could be a placebo affect on some things. But with 'darin and 'vega both pretty much eradicating their gaming issues, it's doing something lol

The one thing I can't chop up to placebo is swiping in my app drawer. I swear I've always felt bad about our app drawer, it would always open quickly but would always stutter from page to page, especially when moving over to the widgets section. Now I can sit here for five minutes flipping back and forth as fast as I can and it will not slow down until I hit the screen with multiple fingers like an idiot lol
[Asus  Eee Pad Transformer Prime] Gage_Hero:
Wipe cache

Hey All,

I read in another post (different site) after applying the build.prop you should boot into recovery and wipe cache and dalvik cache. I have made a few more edits I grabbed from that site and did the wipe. I will report back later once I have run it for a while. Not sure if there is any merit in the statement yet... stand by.
[Asus  Eee Pad Transformer Prime] Mekrel:
Aren't these the wrong commands? The TF201 uses EXT4 and not YAFFS2 and the /system partition is /dev/block/mmcblk0p1

So with that in mind:

If you're unlocked you're going to be running a secure kernel which means you're not going to be able to run adb as root, so even with root and the /system partition mount as r/w; you're not going to be able to push to system:

adb shell
su
mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
exit
exit

adb push build.prop /sdcard/
adb shell
su
cp /sdcard/build.prop /system
chmod 644 /system/build.prop
rm /sdcard/build.prop
exit
exit

Unlocked and with an insecure kernel:

adb shell
su
mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
exit
exit

adb push build.prop /system
adb shell
su
chmod 644 /system/build.prop
exit
exit
[Asus  Eee Pad Transformer Prime] demandarin:
I added this to the OP. thanks

I saw that also. I wasn't sure about it. plus the developer never said we had to do this. its working well for me without doing this. it was also said rebooting twice can make sure certain tweaks take hold. also if nothing noticed immediately, let it cache first. just like some roms here said to do when first flashing them. it has to settle in aka cache.

yeah, someone else noticed the error also. He said something about that command needed to have ReadOnly remounted or something to that nature. that the way the command was, it left it at RW. it needed to be back to readonly like it originally was, once done with commands. he said he was going to write it up once he got off work. Im not proficient with adb commands so any insight appreciated that could help someone in a possible jam. so should I replace those commands in my OP with all you just posted here?

edit: are these commands for unlocked users only, for getting out of a jam? the original guy who posted commands was only rooted and still locked.
[Asus  Eee Pad Transformer Prime] Mekrel:
Yes you should, in regards to being for locked/unlocked users, I posted two sets of commands. Technically three scenarios exist:

Being locked

If you're locked, you're not going to have any third party kernel installed and therefore WILL have a secure kernel and therefore not able to push files to /system. That's why you need the command that involves pushing to the /sdcard and then using su via shell to copy from the /sdcard and then to /system.

Unlocked but with a kernel installed that's still secure

As above

Unlocked but with a kernel installed that's insecure

You can push directly to /system, so you don't have to push to the /sdcard first.

In regards to remounting to read only once finished, you don't have to as you can simply reboot and the commands executed in ramdisk will remount every partition with the relevant flags. Or you could:

adb shell
su
mount -o remount,ro -t ext4 /dev/block/mmcblk0p1 /system
exit
exit
[Asus  Eee Pad Transformer Prime] Danny-B-:
With regards to pushing the build.prop using ADB ...

This should work to fix a boot loop etc too as long as you can connect to your device with ADB

start ADB and type adb devices... it should return the serial number of your device.

You only need to issue the following ...

adb shell
su
mount -o rw,remount /system
adb push c:\build.prop /system/ (change path for your build.prob.. modified or orig)

mount -o ro,remount /system
exit
exit
exit
[Asus  Eee Pad Transformer Prime] demandarin:
I updated thread with all your info. really appreciate it. I credited you with it in OP.

I also quickly learned how to put stuff in bold from copy/pasting your info..lol. I put all this together on the prime itself. didn't even use my keyboard dock for it ;) thanks again.
[Asus  Eee Pad Transformer Prime] RubenRybnik:
Did an AOKP B35 fresh flash from scratch last night( Wipe everything, etc, etc before flashing ROM ) set up all my apps, then foolhardedly tried this without making a fresh backup, and it bit me in the ass. Safe to say it resulted in my having to restore an old backup due to the fact that after flashing this build.prop the Prime wouldn't boot, just got stuck on startup AOKP screen.

After reading the posts about the "Placebo effect", not sure if it's worth the time now to try and add line by line to figure it out. Just wanted to let others know in case their running AOKP and thinking about this.
[Asus  Eee Pad Transformer Prime] it2swbrown:
I did the same but I just reflashed AOKP B35 and gapps without wiping. Basically all it will do is replace the modified build.prop. Booted right back up without issue.
[Asus  Eee Pad Transformer Prime] RubenRybnik:
lol, probably should have tried that first, but it was late at night and I wasn't thinking well ;) Good to know for the future. However still doesn't solve the issue on unlocked, rooted / custom ROM builds trying to run this it seems.
[Asus  Eee Pad Transformer Prime] demandarin:
we have someone who is running this on WSG rom. certain custom roms may need the build. prop tweaked.

plus its well worth it. only like 2 said might be placebo. with one of them still testing further. working great for me n alot of others. alot more than who claim placebo effect..lol.

this stuff is really nothing new. this build.prop tweaks are used universally by developers for phones and tablets. They have real world effects. this one even has tweaks found in CM9 build.prop for performance increases.
[Asus  Eee Pad Transformer Prime] it2swbrown:
It's weird. I loaded up the build.prop unmodified and the prime booted up fine but of course everything saw my prime being on cm9 which for some reason rubbed me the wrong way. I only changed the data that specified cm9 or time stamps, etc and that is when it gave me the splash screen loop.
[Asus  Eee Pad Transformer Prime] ThunderRootedDragon:
I can confirm this does not work on the latest build of AKOP...I did make a backup though. Def wouldn't rush to say it's not worth it w/o trying it first. Would be nice to get Jermaine's input in whether this would be beneficial if tweaked for his ROM. Can't see why he wouldn't integrate it if it did and it was cool with originating dev...he's a solid dev like that.

Thanks to the OP for and orig dev.
[Asus  Eee Pad Transformer Prime] demandarin:
sounds good.

just tell Jermaine to PM me or the OG Developer Seanzscreams. I'd love to hear his insight into this also. The OG dev. has been testing these values for months so it does work.
[Asus  Eee Pad Transformer Prime] Gage_Hero:
If you look for my post, 45 I think, there is a cm 9 build.prop I did. It is for may 7 build but will get the idea. I found that adding com.qc.hardware=true and debug enabletr=true caused a nice bootloop on mine
[Asus  Eee Pad Transformer Prime] bimbobo:
Hi, I am running fw DE21, and my Prime is locked.

I am not used to tweaking. Is there anybody who can write here 2 lines with an idiot-proof guide, about how we can apply the tweak.

My Prime is also rooted. Terminal emulator installed

Somebody can confirm that this tweak works on a locked ATP and with fw that is not US and WW?

Could we ask the devs to make also a DE prop, and upload it together with the WW? :-) :-)
[Asus  Eee Pad Transformer Prime] Rareba:
On WSG 0.7 my Antutu score jumped from 11900 to 13000...not bad! :D
[Asus  Eee Pad Transformer Prime] hairdewx:
I added the tweaks to the build prop for the Team EOS cornerstone nightly build #9

This can only be used for the #9 build because the build.prop is different than the other versions.

You can add this to the first post if you like.
[Asus  Eee Pad Transformer Prime] bimbobo:
It seems easy to read, but sometimes I feel like a "brain dead".

Guys I need help for the Prime on DE 21.. to have this tweak working.

I read all the posts here, but I am not sure about what to do.

I need step by step guide (many other could use it too, I believe).

Thanks
[Asus  Eee Pad Transformer Prime] demandarin:
I saw your pm asking the same thing. hopefully someone who knows how to edit it will come in and make a custom one for you. maybe if you attach a copy of your build.prop up, someone can edit it for you. I would rather someone who has done it before try yours. I never had to do it and was always Leary of it. As messing up while doing it can pit your device in a bind..lol. there are brief instructions in my OP on how to do so. I added it after a few people posted some good tips.
[Asus  Eee Pad Transformer Prime] Mekrel:
If he posts the DE build prop, I'll merge the two files for him (although I'm going to bed right now).
[Asus  Eee Pad Transformer Prime] demandarin:
added to OP..thankx
[Asus  Eee Pad Transformer Prime] acdcking12345:
I tried this again...I grabbed the top file from the list of three. I renamed my current prop file and set the downloaded file to the old file name and set up permissions.

I reboot and black screen again..

Am I doing anything wrong?
[Asus  Eee Pad Transformer Prime] LTLFTCer:
Hi all, I am still having trouble recovering from a blank screen on a rooted but locked Prime when trying out this build.prop Now ADB won't see the device, but Windows will. Any suggestions where to look? I see there are ADB commands that may work to recover, but if I can't connect, then can't communicate.
[Asus  Eee Pad Transformer Prime] slixzen:
After using this for a little while, I seem to be getting less performance and battery life from this mod. :(
[Asus  Eee Pad Transformer Prime] demandarin:
you make sure your permissions was rw- r-- r--? that's the only thing I can think of. you on u.s. .21, right?

check out this thread http://xdaforums.com/showthread.php?t=1514088. post your situation in there and they can likely get you out the jam.

did you make sure to reboot after doing it? you could even reboot twice to make sure it sticks. but there definitely nothing in here to Jake performance worse or battery life worse. Justin be something else. if anything, stuff would of stayed the same or got better. not worse.
[Asus  Eee Pad Transformer Prime] bimbobo:
Thanks and also to demandarin.

I'll send the build prop in a PM later today.

Do you want a text copy or can I zip it and send it to you?

Thanks in advance. :):)
[Asus  Eee Pad Transformer Prime] demandarin:
you can just zip it and attach it to a post here for Mekrel to work his magic on it. make a zip of the original build.prop file you have.
[Asus  Eee Pad Transformer Prime] indie13:
Well, i just waned to add my experience of this.

I was trying to sell my prime due to he poor general performance, slow speeds of everything like installing apps and the like. I really missed my tf101 too, i should never have sold it.

Anyhow, i thought i would give this a go as a last chance for the 201. And a it happens i think this has had a big effect on the device. It seems a lot quicker as a whole and apps even install quicker. I'm very happy with this mod and i recommend others to give it a try. It may just stop you from smashing your device or selling it.
[Asus  Eee Pad Transformer Prime] RubenRybnik:
I'll try this when the OP has a build.prop for Unlocked, Rooted TF201's running AOKP I've already went through twice trying to find the offending line and end up having to restore a backup each time. Maybe if I have time later this week I'll try again, but have other things on my plate right now unfortunatly.
[Asus  Eee Pad Transformer Prime] fabolous02000:
I have the same problem I fixed permissions properly and still blank screen. I'm using the lastest virtuous prime rom.
[Asus  Eee Pad Transformer Prime] demandarin:
I suggest go into recovery &restore your backup and you should be fine. there must be a part conflicting with the rom you running. not sure what it could be.
[Asus  Eee Pad Transformer Prime] demandarin:
great to hear. glad its changing your mind on your prime.
[Asus  Eee Pad Transformer Prime] bimbobo:
Here is my build.prop.

Remember my Prima is DE 21 and rooted locked :p

Has anybody had "gain" from this new custom prop?

What is the biggest advantage?

Thanks in advance

@Mekrel, Please explain also how to replace the default one.

I have copy of this saved just in case.

How do I move the custom one to the Prime?

Thanks
[Asus  Eee Pad Transformer Prime] demandarin:
there are lots of people who has gains. just read the posts in here and in the 300 thread..lol

people need to relealize this is not some mod THST will make your prime run @ 3ghz speed..lol

this is a mod for real world results. it will improve the overall performance, feel, and responsiveness of the prime. it should also improve battery life. these tweaks are nothing new. its used all over xda by developers in their customs roms for tablets and phones. this mod even has some performance tweaks from cm9. you can open up a custom rom build.prop and likely see some of the same things inside it. these tweaks are tried and proven across several different devices.

just Google build.prop tweaks and you will see. ;)
[Asus  Eee Pad Transformer Prime] jermaine151:
I'm going to try to add these tweaks and post a tweaked build.prop to my thread. I'll find the offending tweak and get it sorted out.

Thanks demandarin!
[Asus  Eee Pad Transformer Prime] demandarin:
yeah, just let me know and ill add it here also. if it'll work across the different versions of your builds also.
[Asus  Eee Pad Transformer Prime] jermaine151:
Will do. It should work for every build since I don't change the build properties often.
[Asus  Eee Pad Transformer Prime] Mekrel:
Try this, but you need to ensure you have the Asus ADB drivers installed otherwise the below won't work:

Close Asus Sync on your computer if it's running

Unpack the attached zip

Connect your TF201 via USB and the other side to the tablet itself (not the keyboard dock)

Wait until your TF201 is connected (when Windows recognises it and asks if you want to view files etc)

Run the Runme.cmd

Wait until it's finished

Reboot your TF201
