[Asus Transformer TF700] Pretoriano80:
At least the OP here is honest and doesn't claim that JB is out and is really easier to follow this install method here and share user experience with it. Two different topics imo.
[Asus Transformer TF700] jaxboater:
Thx for the assist.

I got recovery back and I'm playing around with back ups.

If I can restore to ICS I assume that I should use Voodoo to set up for root under TF300 JB.

Again, thx.
[Asus Transformer TF700] ultramegaman963:
i tried that. it seems like you need to let android start up. go to the play store and install super user. than go into your recovery and flash the superuser.zip

not sure why you need to do this.
[Asus Transformer TF700] Pretoriano80:
User over the TF300 forum reported some failures when trying to get back to ICS (aka downgrade) and afaik the only way to downgrade is flashing the blob firmware directly using ADB commands.

Can you guys tell us if the bootloader is the same after installing this JB version.?
[Asus Transformer TF700] kabauterman:
I've downloaded 4.1 ROM for TF300T, installed it via TWRP on my Unlocked TF700T

and I have to say...

I RUNS JUST FINE! :laugh:

[Asus Transformer TF700] ultramegaman963:
you can roll back by following these steps. i pulled it from the "JB is out" forum on xda.

[TF300TG][Guide] Flashing back the original stock ROM

Hi everyone,

I'm owning A TF300TG model and I recently tried to flash one of the ROMS referrenced on those forums and by doing so I found out that my tablet had lost the 3G features so I had to flash back the Asus stock ROM to get it back.

Since I saw many of you got trouble reinstalling the stock ROM, I decided to write a quick guide on how to do it so everyone could get their tablet fully working again

Note: For the record, when I did the following operations, I already had unlocked the bootloader and installed the CWM recovery.

Quote:

Disclaimer:

By following this guide, you will have to issue commands that risk to damage (aka. brick) your tablet or at least void your warranty. I won't be responsible for any damage made to your device. You've been warned.

Download the stock ROM zip file on Asus website (current version is [WW | TW]_epaduser9_4_4_28_1UpdateLauncher.zip) for the TF300TG tablet. Be sure to download the firmware matching your SKU.

Unzip the downloaded file, you will get another archive called , unzip this one too

You should end up with several file, with one of them called blob

For the next step, you will need to install the Android SDK to get the fastboot utility. If you do not know how to use fastboot, you should take a look at this guide.

Once you have installed fastboot, boot your tablet into fastboot mode (Plugin your tablet on your computer's USB, Hold down Power+VolDown, dont press VolUp when prompted, select the USB icon and press VolUp)

Open a command line terminal and navigate to the folder containing the blob file.

Then type the following command:

Quote:

fastboot -i 0x0B05 flash system blob

For some reason, the transfer seems to fail from time to time, if so, just try again by going back to previous step.

Once the transfer is done and you get that sweet "SUCCESS" printed on your screen, just type the following command to reboot your tablet:

Quote:

fastboot -i 0x0B05 reboot
[Asus Transformer TF700] ultramegaman963:
first problem i can see is that you can adjust the brightness from the menu. weird
[Asus Transformer TF700] jaxboater:
Yeah, I noticed that too & couldn't figure out how to dim.

But Weather Bug & GPS work great.

Back on ICS for a bit.

[Asus Transformer TF700] kabauterman:
Display is the only big difference between 700 and 300

so its the only thins what doesnt work :)

€: bootloader is also updated!
[Asus Transformer TF700] Pretoriano80:
Oh, looking at the Kernel version on my gf tf300 i noticed a small difference... On tf300 is showing "Jupiter" but on the screenshot from tf700 is named "Uranus".
[Asus Transformer TF700] Vo01985:
Yeah don't complain about him making this thread, it's not fun swimming through 40 pages of text. Good job on the confirmation. I'll probably wait until the official OTA releases.

[Asus Transformer TF700] Pretoriano80:
Another difference is that tf300 doesn't have haptic feedback and also i can't find the " Music Effects" in Audio settings.

BTW, can you tell us the bootloader version after update? THX
[Asus Transformer TF700] hiemanshu:
Can you post a system image up from your tf700 so others can restore from it and someone can make a flashable zip or a custom rom
[Asus Transformer TF700] ultramegaman963:
definitely. not sure where i can upload such a large file though???
[Asus Transformer TF700] kabauterman:
Bootloader Version is same as the Build-Version: 10.4.2.9

about the Kernel, my TF700T shows Jupiter as Kernel.

About Clock speeds, SetCPU says it still clocks up to 1700 MHz

I think this would not be possible, because you can't "backup" the new bootloader

and you need the new bootloader to run JB.

I can do a system dump upload it and all, but I'm quiet sure that It will not run..
[Asus Transformer TF700] Nebucatnetzer:
How fluid is it?
[Asus Transformer TF700] kabauterman:
better, but still not "optimal" Chrome is still lagging but UI seems to be a lot more fluid!

Chrome should be an App problem, maybe with the Display Res.

Another issue... I can't change my LCD Density with the build.prop

after all the build.prop looks a lot different now.
[Asus Transformer TF700] hiemanshu:
Media fire? Or drop box or box.net
[Asus Transformer TF700] Pretoriano80:
@ ultramegaman963 : I see your kernel version is Uranus, is that correct? So my guess would be that you get that name based on the device SKU version.
[Asus Transformer TF700] kabauterman:
I've used WW SKU JB Update for mine. So Maybe you are right.

€: don't try to change you LCD Density, it will brick your ROM!

€: @jaxboater

how did you get back to ICS? via TWRP? It doesn't work in my case!
[Asus Transformer TF700] jaxboater:
Yeah, after I got TWRP back on I wiped and had no problem.

I may just go back to JB later today.

Weather Bug works and my old eyes don't mind the bright display.
[Asus Transformer TF700] Vo01985:
That's quite low, no? I am getting about 13500 on performance mode. What does your CPU speed say?
[Asus Transformer TF700] ultramegaman963:
brightness can be changed with the app "lux" its probably just something embedded int he system config thats wrong.
[Asus Transformer TF700] kabauterman:
did you used your backup or the ICS ASUS ROM for the TF700 ?

I mentioned that the screen rotation is a lot faster now!

[Asus Transformer TF700] Einride:
Looking at source code for the current TF700 kernel, it checks for board versions (via GPIO) and sets the clocks and voltages accordingly. So as long as the TF700 check is included in the JB kernel, it should use the correct settings. Which it seems to be doing :)

Here's hoping Asus now has a common kernel source base for all three current Transformer devices since they've moved to kernel 3.x (well, 3.1 at least). Looking forward to the kernel source release for these devices to compare them.
[Asus Transformer TF700] kabauterman:
I still haven't managed to go back to ICS.

not with ASUS ROM, not with Custom-ROM, not with Backup! No way in TWRP. It installs but just Bootscreen after this.

I will try to Install the ASUS ICS ROM from the Stock JB recovery now.

@jaxboater:

did you have ever seen JB running?

I realy cant go back to ICS because Bootloader downgrade brings signature missmatch.

So far! No downgrade from JB after this flash!!
[Asus Transformer TF700] Pretoriano80:
Mate there's no way to downgrade using the recovery (stock or custom) and you have to use the firmware blob. Have a look at the Downgrade Guide in my How-To thread but keep in mind that is for tf300 so no guarantee that it will work for you. Also you could try the Fastboot method posted by ultramegaman963 a few pages back.
[Asus Transformer TF700] jaxboater:
I ran JB for a while and then went back to ICS.

Got back by finally getting twrp recovery & then did a wipe & used my most recent back up.

I could not flash ICS via sd card.

I'm back on JB & will twrp back up soon and see if I can just switch from one back up to the other.

Give me 30 mins and I'll advise.
[Asus Transformer TF700] hiemanshu:
While you're at it, care to post the /system backup from JB. It would be very helpful.
[Asus Transformer TF700] gmfeny:
You dont need to be rooted or unlocked for this to work. Its just like installing a firmware update from asus site except its for the tf300. Only problem if your not rooted or unlocked is downgraded. I would be careful not to brick bc of the updated bootloader.
[Asus Transformer TF700] b3z:
Check out: https://github.com/AndroidRoot/BlobTools

Perhaps we can extract the bootloader from 0.26 blob and flash using fastboot.

Anyone know how to use githubs? I'm a noob :)
[Asus Transformer TF700] Pretoriano80:
Are you sure mate? I'm asking because usually Asus have a signature check so normally you can't update with a firmware wich is not designed for that specific device.
[Asus Transformer TF700] ayman07:
how come when i try to flash the update via TWRP it says failed? i downloaded it directly from the ASUS site
[Asus Transformer TF700] jaxboater:
Don't mind at all.

As soon as I get done flipping back & forth let me know what it is you'd like & how to get it and I'll post (if small) or Box it (if large).

Just finished going from JB back to ICS via twrp and then back to JB just now.

A couple of notes:

As has been stated TAKE CARE in playing around with twrp backups!!!

YMMV

The date of the JB back up I did just a little bit ago is dated 1999-12-31--18-00-33

Almost all my Google Play apps need to be updated.

I've been lucky.
[Asus Transformer TF700] Lufterfischer:
Try extracting the zip inside the zip and then flashing that .. I think i had to do that for it to work
[Asus Transformer TF700] kabauterman:
JB TF700T is not regnized by adb :/

I will try at my Home PC, here at work I had serveral problems with adb times before

I did the same first, just wanted to restore my ICS Backup what I made before I tried JB.

But no way, stuck at boot screen.
[Asus Transformer TF700] Curious!:
this thread should go to the "Development" section
[Asus Transformer TF700] gmfeny:
Lol im not sure but by watching he videos posted by 2 different people neither tab said this device is unlocked while booting up
[Asus Transformer TF700] Prax:
I can confirm you DO NOT need a unlocked device to update to this version. I just extracted the zip file from the original zip file downloaded onto the root of the internal SD card. I rebooted and it detected the update file and started the update process. VooDoo root keeper DID NOT work, and brightness/super IPS also do not work. Everything else worked fine from what I can tell, also I did not update gapps as they were internal to the update, when the system finished booting google search updated to get the most current version but google now worked before that update. Please let me know if you have any questions.

Thanks,

Prax
[Asus Transformer TF700] buhohitr:
I have stock ICS max is 1.7?
[Asus Transformer TF700] Pretoriano80:
Yeah, i've seen the video from the guy that posted about this method but i wasn't sure. In this case Asus have an issue here because this means you can install a firmware not designed for this device without voiding the warranty :D
[Asus Transformer TF700] MysticMgcn:
He just beat me to the punch :)

I'm currently trying to find a way to revert back to TF700 ICS with the new bootloader. Haven't gotten far yet but I'll soon be making a post in dev highlighting ways to install and anything else I've discovered.
[Asus Transformer TF700] kabauterman:
Downgrade Methods doesn't work, after reboot no Update-Screen just again JB boots up...

now I try the fastboot method...
[Asus Transformer TF700] gmfeny:
Theyre probably both signed the same. Very similar devices
[Asus Transformer TF700] MysticMgcn:
The signature check only prevents you from DOWNGRADING firmware from what I can tell...

Oh and brightness does work as does IPS+ just give your device time to settle. A wipe doesn't hurt either. So far everything is working on mine.
[Asus Transformer TF700] mywingtophone:
So everything works on your device? ? If you can confirm this i will update mine and dont care if i cant get back to ics,
[Asus Transformer TF700] Pretoriano80:
Hi mate, if your bootloader is not unlocked i don't think there's a way to downgrade but you can try to use the Unlock tool to unlock the bootloader from JB. (tf300 users reported that the tool is working on JB too)
[Asus Transformer TF700] okantomi:
Sorry, out of thanks for the day, but, Thanks!

This is a very interesting development.
[Asus Transformer TF700] kabauterman:
lol, so you can Install it with unlocked bootloader

but you still can't go back to ICS with unlocked bootloader coz of signature missmatch
[Asus Transformer TF700] Pretoriano80:
@ kabauterman : so you tried the Method 2 from Wolf Downgrade guide and doesn't work?
[Asus Transformer TF700] MysticMgcn:
Not sure how you'd like me to confirm other than saying "Yeah it works" lol. I'm at work but willing to make a vid if need be but yeah, once everything settled and I did a wipe it's running great. So far the only thning off is I'm pretty sure the DPI is set differently.

I can also confirm that the bootloader can be unlocked from JB using the ASUS tool.
[Asus Transformer TF700] ayman07:
confirmed working. came from zeus rom.
[Asus Transformer TF700] kabauterman:
I did Mehtod one, but not with ADB, with Terminal directly on Device. Should not make a difference.

It takes the time to copy, but after the reboot command there is nothing happening.

And with fastboot I also get the signature Missmatch.
[Asus Transformer TF700] jtrosky:
How is performance compared to Zeus ICS ROM?
[Asus Transformer TF700] Lufterfischer:
I came from Zeus 4.0 and all for me benchmarks did not improve but the overall feel of the tablet is smoother.
[Asus Transformer TF700] Pretoriano80:
You have to use Method 2 (tf300 owners confirmed that working with ics) and do it from your pc ( maybe id doesn't matter but is better to stick with the guide steps).
[Asus Transformer TF700] Prax:
Mine still doesn't work and I did a full wipe did you do anything else different to change that, also my "wake up from dock" option doesn't seem to do anything.
[Asus Transformer TF700] kabauterman:
Guys, as long as there is no way to Go back to the old bootloader, this could mean That we are not bee able to get the offical tf700 rom if it is out.

Tf300 bootloader maybe just accepts tf300 roms..
[Asus Transformer TF700] ooonimrodooo:
This is exactly why I'm waiting to see how this plays out. Thank you all for diving right in tho. You are like pioneers. Your service is greatly appreciated!

Sent from EVO LTE using the XDA app
[Asus Transformer TF700] kabauterman:
The JB Tablet is definatly not regognized by ABD :( (I'm at home now, no ADB Device!)

no way to go back by the steps from the guide
[Asus Transformer TF700] Prax:
I have blacktie from bestbuy which is why I tired, and even if there is a different bootloader, the update util seems for lack of a better term "dumb" enough to accept any file thrown at it as long as it the processor check is passed. So when the offical tf700 jb update drops it should be just as simple as dropping the update on the root of the SD card again.
[Asus Transformer TF700] kabauterman:
still signature missmatch when the flashing should appear!

:(

now I did method 2 with the Terminal because I have no other chance..

Maybe my bootloader is relocked?! But Tablet says its unlocked...
[Asus Transformer TF700] Pretoriano80:
Have you tried to install the ADB drivers manually? Or you could try the universal adb drivers (search on XDA).

EDIT: also make sure that USB debugging is ON
[Asus Transformer TF700] maxal:
ADB worked on the jb custom roms on my tf101 before I sold it.
[Asus Transformer TF700] jjdevega:
Did you install "Super Su" along with super user and re ran voodoo rootkeeper? I believe that was the way to keep root nowadays.
[Asus Transformer TF700] kabauterman:
;) USB-Debugging is ON ...

it doesn't work! ADB is not recognized in any condition.

Even the ADB Device is no more shown in Device Manager, just the MTP!

Can anyone else try to use USB Debugging on his TF700 after JB Update.

by the way..

Terminal is nothing else then adb. So if I can do all steps, but still end in signature missmatch I think there is no way to go back.

If I install the TF300 JB Update it shows up "signature match" under the Device in unlocked...
[Asus Transformer TF700] rdejager:
Ok just installed the TF300 one on my TF700 and it works, boots up and all that stuff, reinstalled TWRP trough fastboot and gonna see if I can get root to work.

Brightness is indeed broke but the rest works just fine. ADB works fine for me. Rooted now aswell, so thats fixed :D

lets check the build.prob :P
[Asus Transformer TF700] lesonal:
I'll wait for the official jb lol ..I have jb on my gnex ...I'll enjoy that for now :D
[Asus Transformer TF700] rdejager:
Looked at it, almost the same as the ICS one from the TF700, though DPI set to 160 out of the box. so :P that is funny XD and a dpi changer prog can not read the config file :P
[Asus Transformer TF700] Lufterfischer:
Hmm everything Works for Me too, except brightness...
[Asus Transformer TF700] Prax:
Have you tried to change the build.prop file to the higher DPI settings? I heard someone tried earlier and it bricked their devices, I would be interested if its possible, and I would love to figure out how someone got their brightness to work mine still doesn't.
[Asus Transformer TF700] kabauterman:
DPI Chaning end up in re installing your JB! I have tried it.

Can anyone else try to go back to ICS TF700 ROM?
[Asus Transformer TF700] DMardroid:
P

Just to chime in from the tf300 world, those who have taken the JB ota are currently unable to downgrade or flash any ROMs like cm10 anymore BC it uses the ICS boot loader, kernel, mods and such. And no fix atm. So we're stuck w/ stock jb til then. But our tf300 is blessed to have a dev that made a super tweaked out stock base jb ROM tho :D

BTW this interesting stuff happening with your guys' 700

If this is actually working, someone might wanna try our "melted butter HyDRo ROM" that works w/ JB bootloader

[Asus Transformer TF700] MysticMgcn:
Did you use an app or change it in the build.prop?
[Asus Transformer TF700] kabauterman:
tried both.. and the apps also just do the same as u do manually
[Asus Transformer TF700] rdejager:
Changed it, nothing happend for me, still the same.
[Asus Transformer TF700] Nebucatnetzer:
Hm this could lead to multiple device ROMs. Imagine how awesome that would be.
[Asus Transformer TF700] Pretoriano80:
Speaking about TF300T and JB... Afaik they needed a special TWRP recovery for use on Jelly Bean so i wonder how is possible that on the Infinity the "old" ICS recovery is still working with JB too.
[Asus Transformer TF700] MysticMgcn:
Skipped using the app. Used Root Browser to edit to 240. Didn't have to reinstall but didn't change anything for me either. And yes I rebooted after...

:p
[Asus Transformer TF700] urrlyx:
ahhh... that would be why the zip i made that only flashes the system and kernel hangs on boot then. good to know.
[Asus Transformer TF700] MysticMgcn:
No luck downgrading yet, tried everything both rooted and unrooted, locked and unlocked bootloader.

I bet if a dev could unpack the blob and rip out the bootloader for a flashable .zip if we could have a "safe" installer for everyone. The bootloader seems to only check for older versions, not newer, so it should work.
[Asus Transformer TF700] hiemanshu:
I am working on a flashable zip ATM. But will take a little time.
[Asus Transformer TF700] MysticMgcn:
Just saw this after posting. So we're sure now we need the new bootloader for JB to run?
[Asus Transformer TF700] urrlyx:
Not necessarily. I'm not certain the kernel was flashing correctly, so that may have been it too. I have the individual blobs all extracted. I'll see about uploading them in a few.

edit: to anyone with blobtools experience: can you extract all the partitions and repack just the system and boot blobs and successfully apply that? ie - don't include the bootloader, recovery, or partition table blobs. i repacked a blob as described, but i'm wary of even trying it as i've never done any repacking before.

edit2: and now that i've thought about it (durrr) i don't need to repack into a single blob. i can just flash the individual blobs to system and boot. ill try that out in a bit.

/yay brain slowly starting to work again after long vacation. :P
[Asus Transformer TF700] MysticMgcn:
Just to take a step back how concerned do we really need to be with the bootloader? Other than not being able to downgrade (yet I'm sure) when ASUS releases the TF700 JB it could have the same or newer bootloader. And if it is newer I doubt we'll have an issue with it. I guess if nothing else we're being really prepared and have a nice start on understanding the system and maybe to find a way for people to downgrade.:highfive:

With this being the case, as long as things aren't drastically different when the JB and the upgraded bootloader are actually released for tf700. Roms for the tf300 would be easily ported to the tf700. Devs can join forces. This is great. Since things got off a little slow for the tf700, we will see a very fast increase in development. am i right?

Hi guys! Just wanted to throw the third (bastard) brother into the mix. Want to try this on the Prime, just to be clear on how you did this;

Download latest TF300T rom from Asus, unzip to get another zip. Wipe like a madman, then flash the official jb and gapps, and then bingo?

Thanks

Lufterfischer, Games etc?

[Asus Transformer TF700] Thats OK:
I was wondering about this a few days ago.

But man I'm not ready to risk it...plus I need to do a lot more reading about doing it.

Maybe if Asus gets wind of Infinity tweakers doing this they'll just go ahead and push an update out.

Might be a cheap way for them to test case the 4.1 update.

If it works it works!
