Just ran it.

Quadrant before w/Modaco hack: 907.

Quadrant after: 2250!!!

Well, just surprised as I never ran quadrant before. I used modaco hack awhile back which did limit you when you tried to install apps which store stuff on /apps partition such as Sims, but it worked. Didn't really want to try JAC's stuff because I was never fan of storing this stuff on my external card, primarily why I never used APPS2SD.

Lets see if this phone is faster now! Thanks for sharing the link :).
[Vibrant Android Development] NickAtNite:
Oh man, I can't wait to get home so I can try this out. I'm currently getting 1450 on quadrant using the sd ext3 partition hack. I was pretty satisfied with that until I saw this.
[Vibrant Android Development] Freedomcaller:
can i add that to the first post?
[Vibrant Android Development] JustinLoe:
Did the same thing. Using the updated 2nd batch script. Getting really ****ing old and tired to get to "normal".

logcat; bootloop
[Vibrant Android Development] Argusi:
Edited... 93 meg left from a bare stock phone with v2. Bleh. Back to the drawing board.
[Vibrant Android Development] dog911:
I got the phone to start again but looks like the tmobile boot screen is gone lol

wth.
[Vibrant Android Development] Civil Disobedient:
this happened to me. See thread. http://xdaforums.com/showthread.php?t=750866 I got everything sorted, but haven't tried to do the speed fix yet. I are nervous.
[Vibrant Android Development] jtguthrie1:
WORKS!!

Yes that app worked. the first one just says are you sure sdcard is mounted?" the _v4 apk worked wonderfully
[Vibrant Android Development] jtguthrie1:
So i Installed the 2.1 Eclair .zip and the vibrant4.zip with RyanZA lag fix and im running 2900 quad. Thx to all who made these.
[Vibrant Android Development] xspeed9190:

[Vibrant Android Development] robavila721:
used the 2.0 and it left me with only 93mb of memory for apps giving me a "low memory" message, i liked the first one better as it left me with one gig at least
[Vibrant Android Development] SE7EN-:
Used the update.zip version works perfect and I still have 500mb left over for apps.
[Vibrant Android Development] masr1979:
Guys as far as I'm aware, this creates a 1GB, or 1.7GB in v2 file whiting your internal memory, and creates a virtual EXT2 partition INSIDE that file, so your phone is telling you you have 90, 293, 500, etc, etc MB free, but that's counting the 1GB file that holds your EXT2 virtual partition where your apps get installed in, so you're not using the space that your phone tells you is free to install apps, but the space within the virtual EXT2 partition.

I guess some need to modify the script so that the file that is created isn't as big, so that it will leave at least 300MB of free space on the internal card and avoid the low storage warning.
[Vibrant Android Development] srqt:
Same, No Power on wav or boot animation. Any thoughts?

Also superuser is not remembering permissions after this which is really annoying
[Vibrant Android Development] dog911:
I just flash back to stock rom :D

got to wait untill better method of doing this
[Vibrant Android Development] tq745:
i did the update.zip method...i'm still showing a quadrant score of around 880. i have busybox 1.17.1 installed, rooted, with the stock recovery and rom. don't know what i'm doing wrong,...
[Vibrant Android Development] hukkguai:
Thanks for the instructions! Made this a super easy process for me. Took me like 15-20 minutes total from start to finish.

P.S. Just watched the movie "The Crazies," are you from the same Ogden as the movie? lol
[Vibrant Android Development] mesajoejoe:
care to explain exactly how you accomplished this?
[Vibrant Android Development] zimphishmonger:
Has anyone run into any strange issues (that would be caused by data corruption of dalvik-cache and app data). Although I know EXT2 is prone to corruption, especially with all the restarting a phone does, has anyone actually experienced it yet?

I am personally using a Virtual EXT4 loopback, which handles that corruption issue, although it does bring down the benchmarks a bit (to around ~1700, 1900 OCed). Better to have data security due to the journaled file system than a lil extra I/O boost, imo.

Interested anyways :)
[Vibrant Android Development] jtguthrie1:
Skills? Lol took a little. . I installed the stock 2.1, then rooted. . Then downloaded rom manager. . Then clockwork mod. . Then added the vibrant4.zip. . Then booted into recovery. . Go to reinstall packages. . Click install zip from file. . Find the vibrant4.zip. . Install. . Then reboot. . After boot up run the ryanZA_v4. . Honestly takes 20 min. . But after that worked like a dream. .
[Vibrant Android Development] jtguthrie1:
That help?
[Vibrant Android Development] PowSniffer0110:
No problem, and no haha ogden utah
[Vibrant Android Development] Xyber3364:
works so far.

Hey guys, just did a clear/wipe -> root than i did the shell script manually and so far quadrant score is over 2000 and have not seen any problems.
[Vibrant Android Development] j56bp:
is this version would be for a booted stock phone?? plz advice

my phone only booted nothing alse............witch file should i use to speed it up ??

can some 1 plz advice me with step by step info....( i need speed ...lol)

ps.....noob need help
[Vibrant Android Development] lexluthor:
Maybe I missed it and I'm not the one who uses the Vibrant (my wife does), but what probablem exactly is this fixing? Where is the problem noticed when using the phone normally?
[Vibrant Android Development] mesajoejoe:
I misread the post i previously quoted. I thought it said you flashed a 2.1 eclair rom, THEN flashed Vibrant4, then lagfix. But i just reread it and i get how you meant it. Thanks though for the explanation lol.
[Vibrant Android Development] Ashido:
What would be the side effects of applying this fix? I'm still on the fence to rooting and stuff because I don't want this phone to turn out to be a mess like my G1 did.
[Vibrant Android Development] hockeyrcks9901:
I installed the original version already, can someone explain what the benefit of doing the version 2 fix would be/is?

I'm having no issues with the original fix as it is now and no low memory warnings either.

Thank you.
[Vibrant Android Development] mygti02:
can someone explain what the difference is between the 512MB version and the 1Gb version, besides the size. Is there a speed difference between the two?
[Vibrant Android Development] Gr8gorilla:
here is a link to an update.zip that sets all of this up for you. works with or without clockwork. This is also in beta testing. It may or may not work. I am using it and it seems ok. This is from RyanZA's 2.0 thread.

New Version 2.0 Here!
[Vibrant Android Development] lexluthor:
What real world improvements will I see if I run this?

On my Vibrant, when I go to market download page, it takes a really long time to open up. On my Droid X, it opens right up.

Is that some other problem with my Vibrant or will this fix that?

If I have a Stock Vibrant, currently without root, which process/file should I bet using?
[Vibrant Android Development] t1h5ta3:
whats realy sweet is looking @ tne N1 and the improvement in cpu between 2.1 & 2.2! JIT makes it scream!

just wait till were running 2.2 w/ JIT and the I/O speed tweek!!!!! :eek:

thank you for shareing!
[Vibrant Android Development] mygti02:
everyone be careful running that new 2.0 version. My device wont boot now.....gets to the galaxy S screen then goes black.
[Vibrant Android Development] mygti02:
anyone have a link for the stock Tmo image? this 2.0 update screwed up my phone to all hell. Thanks for the help.
[Vibrant Android Development] Gr8gorilla:
Thread here on dev called "Fix any brick"
[Vibrant Android Development] PowSniffer0110:
Yes it fixes the market lag and boosts the overall performance of my phone Ive noticed. Boots up faster, loads things faster. Recommended
[Vibrant Android Development] lexluthor:
Thanks. Will try it. How about the 2nd part of my question then?

If I have a Stock Vibrant, currently without root, which process/file should I bet using? There appear to be so many different variations.

Also, is it easily reversible?
[Vibrant Android Development] rei165:
The 2.0 update, will it create the virtual partition on the internal SD or will it be on the application data part of the SD card?
[Vibrant Android Development] Calcvictim:
internal SD
[Vibrant Android Development] mygti02:
so im using odin to reflash my phone to stock since 2.0 update screwed my phone up.....i added the files necessary in ODIN and clicked start and its sitting at cache.rfs, I know the Dev said to be patient, but its been there for 15 minutes....im thinking thats not right?

UPDATE: Well the phone restarted itself, now all i get on the screen is a little cell phone and a computer with a ! between them. I cant get into download mode, i cant boot the phone, i cant do anything. WTF just happened? anyone have any ideas?
[Vibrant Android Development] PowSniffer0110:
I would just recommend rooting and getting superuser.. Its not harmless and adds functionality and purpose. Then read my post early on here for details how to install via update.zip process
[Vibrant Android Development] ttabbal:
That's a protection mechanism to prevent you from booting a phone with a possibly damaged file system. Not a big deal, you CAN get to download mode from there. There's a whole thread about it, but IIRC you can pull the battery, then put it back and plug into the computer. Wait for the green battery screen, then hold vol up and down along with power. When the screen goes black, release power, keep vol up/down pressed. It should bring you to download mode from there. Then Odin again. Sometimes it screws up, no big deal. It shouldn't take more than about 5min to reflash, so if you get to 15, time to try again. Odin does update the screen while it's running as well, so you can tell if it's working.

I've read that some people have better luck getting Odin and download mode by removing the SIM and SD cards. No idea if that matters, I have always left mine in and it worked fine.
[Vibrant Android Development] zimphishmonger:
Ive run into this a TON of times. Its a huge PITA but you can get it to boot into download mode. Ive had the best results by plugging it in to USB, holding both volume and power, and let go of power as soon as the screen goes black. Ive actually noticed it doesnt show the charging animation when in this mode, so you cant use that as a crutch, as ttabal mentioned above. If it doesnt work, try again. It took me 15 times last night to get into download mode after a kernel flash froze, but I did it (and will most likely have to do it again....I hate ODIN).
[Vibrant Android Development] de_dragon:
Thanks

Thanks!!!!!! 2221 in Quadrant. Running great. :D
[Vibrant Android Development] ram100987:
I didn't see it mentioned, will this conflict with the /data/data to /dbdata lag fix?
[Vibrant Android Development] mygti02:
this worked, thank you guys so much.....the battery meter would not come up, then i saw your post that sometimes it wont come up. anyways, its back up and running. I may exchange it anyways just so i know it brand spanking new, since i have the chance to do it. thanks again guys, your the best. Love XDA :)
[Vibrant Android Development] DSK123:
Followed these instructions and everything went perfect. Quadrant gave me a 2200+ rating and I'm one happy Vibrant owner!
[Vibrant Android Development] pittphan:
Help

Hey I ran the update zip and then the SL4A and it worked but now almost all of my apps are missing! Including the Market - so I can not redownload them.

Even more, I looked in my settings, manage apps, and they are all still there, but I have no idea how to reinstall them or run them.... please help?

Update: I figured it out. Luckily I had root explorer and I got into /System/app and I reinstalled the vending.apk... I can now also reinstall all the other .apk's as well... whew what a relief... major PITA
[Vibrant Android Development] skater4690:
try using droidexplorer it works wonders and saves me from situations like that. you can use droidexplorer to reinstall the apps if the apks are still on your phone
[Vibrant Android Development] ellopr:
Can someone post the introduction to convert to the lookpack to ext4. Thanks in advance!
[Vibrant Android Development] pittphan:
Thanks. That's actually what I've been doing... but how do I get the market back?
[Vibrant Android Development] cwalker29:
Dont know about the rest of y'all but for some reason my phone wont wake up when in sleep mode after adding this hack.. I would have to pull the battery out and the reboot the phone back up. But after a couple minutes the same thing happen. Dunno why but I need a bug free version. Anybody else having this problem?
[Vibrant Android Development] zimphishmonger:
There are NINE pages of issues......any attempt at reading them? Also, as this mod is very experimental, there wont be a bug-free version for a while. Maybe try back in a while when things have settled down.
[Vibrant Android Development] jaker.the.skater:
ok so i read through all 43 pages. i just want to make sure.

i have a rooted vibrant with superuser. as long as i install the 1.17 busybox i can do either the .bat file way or the update.zip?

ive never had clockwork recovery or used odin or anything like that or flashed any roms. just straight root.
[Vibrant Android Development] zimphishmonger:
You need clockwork recovery (and if you haven't up until now, you DEF will after trying this mod). If you apply this mod w/o doing a nandroid backup using clockwork, I almost guarantee you will end up restoring your phone back to stock settings because something went wrong.

If you insist, i recommend using the bat method as you can actually see error messages, and have something to go off of instead of "I waited for hours and nothing happened" using the apk method.
[Vibrant Android Development] jaker.the.skater:
thanks man. will try clockwork and then the lag fix.
[Vibrant Android Development] jaker.the.skater:
sorry for the double post. but one LAST question. should i be using the update 1,2,3, or 4 from the op?
[Vibrant Android Development] Janis:
You asked if this works on Vibrant. I tried it on mine, completely stock but rooted, and after trying to run the script (it didn't run) the phone shut down on its own and I was stuck in boot loop. I'm not an expert, but what it looked like was that there was no data file to write to, so nothing could go.

I tried reflashing, and wiping plus somehow (not sure which update.zips I tried) I got into the OS, and got FCs for all of the stock apps that run at boot. Was able to sit and click on them til they stopped, mount the internal SD to copy it to my PC just in case I eneded up at the Tmo store for a replacement.

Today I got Odin up and reflashed, but not until after three stalls.

I'm just one tester, but I'd only try this without any apps (I had a bunch, but not much data accrued yet, caches cleared, about 50-60mb), and then only if I had time to flash a fresh ROM if it didn't work.
[Vibrant Android Development] Relikk356:
I used the update.zip posted by Beckham. It's extremely easy. I will go through directions one more time, even though they are on here at least three times now.

1. Phone must be rooted.

2. I used Clockworks recovery Rom Manager. It seems like there are other ones you can use to, but I used Clockworks recovery Rom Manager, so get that.

3. I would advise to run a backup first using the Rom manger, just incase. Find directions on how to do that under the Vibrant general section of this forum, Under tips and tricks.

4. After backups done, access your phones internal SD card through your PC. Check and see if there is already a file called update.zip on your phone. If there is move it to a safe place. This prevents you from overwriting update.zip with the one you downloaded from Beckhams. They are different files with the same name. Now move the new update.zip on your phone.

5.I disconnected my phone from the USB cord (probably do even need to do that), Turned it on, held the volume up/down and power key. Brings me to a prompt screen, I then picked reinstall. Blamo, it did its thing.

6. phone rebooted, went to app drawer ran the new app. Picked the first script, 1024 partition. Let it run for a while. It said completed. Went on my way.

This is verbatim from memory, if you want proper instructions you will find them posted by Beckham.

This is my first Android phone and I’ve had no experience with this before now. I was able to Root my phone, load Eugene’s Vibrant 4 rom, do the manual GPS fix, uninstall a previous fix causing issues that was included in Eugene’s mod, load the captivate camera software, got WIFI Tethering working, and the lag fix without asking one questions and did not have a single issue. What was my secret; I read the directions that are posted on here! Sorry for the run on. I’m not trying to blast anyone particular but there are like 20 peeps asking for directions that are already on here. The Devs who are knowledgeable and experienced enough to make these hacks need to spend their time on the hacks; less time on directions. The instructions are already here if you are willing to read.

No offense to the people who followed directions and had issues.
[Vibrant Android Development] disturkis4u:
I did this method using the batch method and also did the 2.0 version he posted....both times it completes properly but my quadrant score is still around 917...

I have root, superuser, and clockwork...i don't have a custom rom. This version leaves me with 507mb or so of memory and the 2.0 method leaves me with around 200mb...

I don't get any error messages but I'm not sure I'm getting any results from this lag fix....any suggestions?
[Vibrant Android Development] jaker.the.skater:
thank you sir. your help is appreciated.
[Vibrant Android Development] Relikk356:
Did you run Quad for both versions 1.0 and 2.0? They were 900 either way?
[Vibrant Android Development] Gr8gorilla:
RyanZA claims it doesn't matter. That the ext2 is just a buffer. You can look into it more yourself if you want. BTW latest version of his fix 2-3 is doing well with a 2191 quadrant score!
[Vibrant Android Development] disturkis4u:
Yes even after several reboots
[Vibrant Android Development] zimphishmonger:
t certainly does matter, because that buffer can become corrupted fairly easily if it is not unmounted correctly (which is fairly common on a phone). EXT2 is not journaled, and if you run a e2fsck (file system check) on it, you will likely find errors. I added a file system scan on boot, and it found errors everytime.

You may not notice the corruption, but when your phone starts doing strange things, the EXT2 partition is likely to blame.

Also, if you own Quadrant Advanced, you can see how significant the IO boost is by using this mod. It improves IO performance by 5x and easily destroys every other phone in that area, by a mile. However, actual real-world performance comes from balancing all the different areas of the phone: CPU, ram, & storage (IO). If even one one of those is lacking, the whole phone slows down.

By using an EXT4 loopback, we may lose a little performance in exchange for data reliability, but as its STILL faster than any other phone, and wont be an issue for real-world performance.
[Vibrant Android Development] Goog1e Phone:
question: would you recommend using this lag fix or jac's?
[Vibrant Android Development] anomalous3:
I'd go with ext4, teensy performance hit vs ext2 but well worth it as far as avoiding problems.
[Vibrant Android Development] Goog1e Phone:
Yeah, my thoughts exactly, but I'm kinda bummed about the screen wake issue. That's the only thing keeping me away right now.
[Vibrant Android Development] anomalous3:
The ext 4 isn't what causes the screen wake issue; that's the kernel itself. With that said, it will take some tweaking to get the ext4 version to work with the playlogos1 hack, but not much.
[Vibrant Android Development] zimphishmonger:
Ya, JAC has said that its probably something in the source. I believe they are working on that.

Also, why do you need to use the playlogos1 hack? the whole point of the init.d folder is we can run our scripts at boot, in the exact order we want.
[Vibrant Android Development] jaker.the.skater:
thanks for everyones help. got clockwork and lag fix set up fine. got a 2135 on quadrant! cant wait to see what this puppy can do on froyo!
[Vibrant Android Development] anomalous3:
People who want to stick with the stock kernel would need to use the playlogos1 hack; personally I prefer using init.d and don't mind the wake lag so much. Of course, here I am forgetting that the stock kernel doesn't have ext4 support.
[Vibrant Android Development] ellopr:
Still why you don't share with us the commands to upgrade to ext4. I understand how it was done back on the g1 but I prefer to hear from someone that had already done it. I don't mind sacrificing performance for stability. I'm running the ext check command on boot from the useinit.sh before I mount the loopback. Still I prefer to change ext4.
[Vibrant Android Development] JWhipple:
My phone was getting a bit cluttered with stuff I installed but either didn't use or rarely used so I decided to wipe and try this.

Prior to wipe, I ran Quadrant - got an 864. After wipe and implementing this fix, I jumped to a massive 2224 in Quadrant! Ummm, WOW!
[Vibrant Android Development] Minker17:
I've been following this to an extent, but not all 46 pages. If I am understanding correctly, I install the apk, it writes a small ext2 partition and that is it? Can you simply uninstall it to go back to the way it was? And I'm seeing that it's recommended to wipe? Any requirements or is it just root and a nandroid just in case.
[Vibrant Android Development] frankencat:
Everything you need to know about this fix is here...

http://xdaforums.com/showthread.php?t=751864
[Vibrant Android Development] ttabbal:
It's really not hard. But here's the stuff I use in my script to do it. Run from adb shell booted to Clockwork Recovery.

mknod /dev/loop0 b 7 0;
losetup /dev/loop0 /data/linux.ex2;

/system/bin/tune2fs -j /dev/loop0;
/system/bin/tune2fs -O extents,uninit_bg,dir_index /dev/loop0;
/system/bin/e2fsck -fyDC0 /dev/loop0;

Don't try to do too much work in the boot scripts using the playlogos hack, you won't get your mounts up before the OS loads and it will look like you lost data and apps. Even fsck seems to take too long sometimes. That's why I don't do any of my scripts using that method and require init.d + JAC kernel. The wake lag is a small price to pay for reliable boots.

For those not using init.d + JAC Kernel, DON'T convert to ext4. You won't be able to mount it, if the conversion even works, as your kernel won't know how. It can do ext3, so you could do that if you like. Just don't run the second tune2fs command in that case.
[Vibrant Android Development] pekedey:
Holy Cow! I had no idea benchmarking 2200 was even possible! Yet I just ran two quadrant tests in a row after running the lag fix (I just used RyanZA's one-click batch fix). First test was 2224, second was 2179.

Insane! I can't wait to see what 2.2 does to this!
[Vibrant Android Development] djunio:
Great job guys, finally decided to jump in and on glad I did.
[Vibrant Android Development] ransz28:
I did the update but now my font is stuck on the Standard Font. I selected the other fonts, it prompted me to reboot but it still goes and uses the standard default font.

Is there a fix?

It worked..

its rocking fast........... 2100 :D
