Up until recently, I'd been perfectly content with my completely stock Nexus S (T-Mobile, SAMOLED screen, I believe that makes it the i9020T model?). However, the 2.3.4 update made the phone's display look yellowed and washed out.
After looking around on XDA, I found that installing a new kernel with voodoo colors could fix the problem, so I'm looking into doing that. My questions are as follows:
Just to be clear, I need to be rooted and have the bootloader unlocked to proceed with this, right? And if so, these instructions will do for stock 2.3.4?
If I flash this kernel, will I still get OTA updates in the future, and will they work?
If they won't work, what steps would I need to take to get back to the stock kernel?
Thanks in advance!

Good afternoon, everyone. I just had my phone rooted with the Hero ROM and it is very laggy and it cripples the whole experience. Is there anyway that I can unroot my phone to where I'll have the stock Android v1.6 and still get OTA updates (I'm on T-Mobile USA)? If this is possible, can someone direct me as to how to get this done w/o paying for someone to do it for me?
Thanks in advance,

If you have modified recovery (by Amon_RA or Cyanogen) - no need to get unrooted. You can simply flash other ROMs (except official - they sucks)
All the info you'll need is in the first post of this thread.

I was able to unroot my mytouch and receive the ota update for 1.6...but I turned around and rooted it again because I realized the stock kinda sucks. If you follow the instructions, this will get you back on the stock 1.5. If you don't receive the ota update to 1.6 right away, you can use google to find the stand alone update pretty easily. I think I ended up finding it on the tmobile forums.
Thanks, fellas! I appreciate it. It should be fun to see if I can do this by myself
Last question, what is a goldcard? is it essential to have one in order to get the stock ROM back?

a goldcard is a spare sd card that has been modded to allow the unlocking of phones, usually you do it with windows mobile phones, but you dont have to for the mytouch/magic, you can just One-Click root it if you are still on cupcake.
what i am trying to say is, you dont really need it to get back to stock rom (unroot) you just need to flash a few files from my understanding...i have never wanted to unroot so i wouldnt know but if you need a tutorial, i can give you the link for a perfect one.
I used theunlockr(dot)com to unroot. They have a video and text guide.
OK so I followed a youtube video tutorial on rooting,and I think it's the boot.img that messed everything up. It would boot up before but it was stuck on the Google screen, the OS didn't load. So I found a GRH78 or something Nandroid backup and ran that, but the capacative buttons don't work, the screen isn't calibrated correctly and the phone radio isn't correct either. Then I remembered my Nexus S was the newer GT-I9023 GRI54 and I need a GRI54 NANDROID stock backup (which I can't seem to find!)
Guys, what do you suggest I do at this point? I can't revert to stock (I've been trying)
I just got this Nexus S and have been spending hours trying to restore firmwares, finding it online, but now I know I need the GRI54 Android 2.3.3 backup, and if anyone has that I'd be super happy
I really need help
you most likely need the 9023 method of rooting
see the stickied guides
I fixed it. I downloaded a GT-I9023 GRI45 firmware file off of somewhere here (<3 xda forums) it wasn't a nandroid backup, but I used the clockworkmod to install it and surprisingly, it booted up again. (of course, I had the crappy 2.1 installed before so maybe this acted as an 'update' and fixed all the problems, but anyways it works smooth now as it did before )
I knew I could figure it out.
Not to be an ass, but I think there's a lot of difference between bricking a phone and being unable to boot. You've never bricked your phone, since you could still switch ROMs by using the Recovery.
This is a misleading title. Bricking is when you just can't enter not even the bootloader/Recovery.
you are 100% right
unfortunately many people keep getting those 2 terms confused, and use it inappropriately
every body needs to chip in and help newbies learn the correct terminology.
thank you

Looks like I've managed to act and look like a fool...
I tried to root my Nexus S with Superboot, unaware that it was version-specific (I should have known that ). To make a long story short, I tried to root my phone with Superboot which is written for android 2.3.3, while I'm running 2.3.4.
The phone can get to fastboot/recovery, but won't boot. I googled to find how revert to a stock 2.3.3 or 2.3.4, but somehow did not find what I was looking for.
Phone was vanilla, I hadn't installed anything specific on it besides twitter, FB, etc.
From a powered-off phone, how would I manage to revert to a clean phone ?
Thanks for your help, people.

<EDIT:
All the solutions I've seen required CWM or similar, and a rooted phone. Since my problems started because I wanted to root my NS, I figured that I was out of luck for a while, and a non-working phone was out of question.
I went at my retailer and managed to get a new phone free of charge I *****-footed around the fact I was installing an unsupported (by the carrier) update/app, the clerk wasn't very familiar with the NS so it went well with them and they gave me a new phone
/EDIT>
I have seen a few posts in regards to people asking about updating from a rooted device but I never seen the answer I been looking for.
Example: I rooted my Motorola XOOM Tablet, Android 3.2 by following these instructions: http://forum.xda-developers.com/showthread.php?t=1170760
"[GUIDE][US WIFI & 3G] How To Root Your Xoom From 3.2 Stock [PC & Mac]" posted by jase33
IF say for example version 3.3 comes out.. IF I want to upgrade to version 3.3 from my rooted 3.2, Am I able to click upgrade when it announces it? While rooted and unlocked?
I am not using custom ROMS. I just followed those steps provided in the link above.
Do I have to restore to faculty settings, re-lock, then upgrade, then repeat the same process to root all over again? or can I just click upgrade.
Other posts started talking about having custom ROMs, and there wasn't a defendant answer that I saw that was reassuring to my question.
Thanks for your Help
So far ive not had little success updating using the built in update feature, when 3.2 came out I tried updating but it crapped out when booting, so I had to delete the user data, loosing all my apps in the process. But this is based only on the update from 3.1 to 3.2 both stock roms. P.s. i used the same instructions u did on an AU Xoom.

If your Xoom is unlocked but also not rooted/completely stock, you can get OTA updates. If rooted, even stock rom/kernel, you don't get or can't install updates. But if rooted, never fear, our developers, including the Tiamat team have made the updates available to us super fast.
Anyway, you never need to re-lock unless you plan to return the Xoom under warranty, for repair or replacement.
no offense but it sounds like you don't know much bout this sort of stuff...you believe that you are not using custom rom but are not sure?? You need to read up and figure out the basics...if you are using custom rom..absolutely do not accept an over the air update. Read up on what you are doing unless you want a600 dollar paperweight
I am actually more than 100% sure I am not using a custom ROM..
I never downloaded any custom ROMs to be honest that’s how I know.
The only thing I wasn’t sure of at first was the ADB commands but when I was rooting for the first time. But after I read the tutorials it was as easy as riding a bike. As for the small Linux commands used in the shell, from the tutorial that I followed, seemed pretty super basic. I had been using Linux for 6 years, recompiling kernels etc so I don’t have any doubts...
I am not too worried about bricking anything… My question was only related to the OTA updates with the rooted stocked. That’s all.
Thank you everyone for your responses, they answered my question. And thanks for the concerned about my device.
Hi guys,
There are threads on this and I have taken a look. Most solutions to this issue (apparently a radio file that is incompatible with certain devices rolled out with the 2.3.6 update) require a flash (radio, rom etc.).
My phone is unrooted and since I still have the return policy, I don't want to disrupt too much and spend too much time rooting/unrooting just to get it to work.
I'd like to try either a radio flash or a full wipe back to 2.3.5 or 2.3.4 in order to see if this is actually a hardware defect, or a software issue as above.
Can anyone advise on whether or not it will be possible to do a full wipe back to 2.3.5 or earlier without having a rooted phone?
I tried the other thread on flashing the radio but I believe it is not possible without root access.
I apologize for the noob thread, but I could not find an answer to this problem specifically for those with unrooted phones..
Thank you.
Hi there,
There's no way to return to an older version with stock recovery. You would need to root and install a custom recovery. Then you will be able to rollback to the older version of the update.
Since you don't want to do that, the only option is to return the device and get another.
Root is extremelly easy with SuperOneClickRoot (just in case you're afraid of loose too much time on this).
Thanks for the prompt reply.
I guess I was just grasping at straws.
I was following a guid eon nexus hacks for rooting and the process seems relatively quick and painless... would I need superuser installed if all I'm doing is the recovery tools for now?
Its not the rooting part I'm worried with, or the unrooting as there's guides for those (and its quite a simple process) its just the possibility of something messing up along the way
Actually the fastboot unlock and recovery install is pretty painless. Just make sure you have the correct custom recovery for your phone model.
You don't need superuser if you're just running the recovery and have all the roms you will need in you phone's "sdcard"
Fair, I guess if all I'm doing is unlocking fastboot and then am able to "relock" it, it is relatively painless.
This might be a very stupid question and it is a bit OT but since you're active in this thread for the moment, customer recovery... I am a bit at a loss on how to retrieve that from? I was merely hoping that by unlocking fast boot, I can just "flash" in a radio file, but I assume I should backup those radio files first...
You are correct. Just flash the correct radio and you're good to go.

Hi guys,
I've searched everywhere and can't get a definitive answer on this so here goes -
I'm a noob when it comes to Android, having recently defected from being an Apple Disciple (I got hacked off with iTunes and bored in general with the Daycare Centre which is iOS) and have recently acquired an Acer A700 tablet.
I have installed the JB update OTA and everything is working fine and am chomping at the bit to get it booted, but most of the posts I have read regarding unlocking the bootloader and rooting it relate to ICS.
My questions are -
Does the bootloader process apply regardless of Firmware? (Are there different versions for different Firmwares)
Can anyone point me in the direction of a decent tutorial on how to do this?
What happens regarding a future update? Do I have to revert back to stock and update from there or can i jump from one ROM to another? (I'm assuming that I can't use the OTA updates any more)
Sorry for the long OP and thanks in advance for your answers.

No problem. Seeing you are on JB, then you have a JB bootloader.
You need to go here http://forum.xda-developers.com/showthread.php?t=1953917
And download Vorbeths easyroot2.0. It's for the 700.
You have to unlock your bootloader first, which shouldn't be an issue for you. Easy instructions for that.
Then download his package to a folder on your PC. (not sure, but you may have to download each file individually) Open a command window (shift & right mouse click) and type in whatever his instructions say. Should be painless.
Make sure USB Debugging is turned on first in your tablet (Settings/Developer Options/USB Debugging), and make sure you have the Acer Drivers installed on your PC.
Then connect, wait 30 seconds, and run his batch file.
You should be ok.

Oh yes, one more thing, once you unlock your bootloader, chances are you will not be able to get OTA. And the only way to re-lock the bootloader is to install a stock rom.
Thanks!
Thanks for the reply. I am now the owner of a fully rooted A700!
Had a few issues during unlocking the bootloader. That thing timeouts quick! Also, didn't realise you had to run the .bat file while the tablet was on the Bootloader USB protocol screen. I thought you had to wait until it booted fully into JB.
Anyway, took the plunge and thanks again for your help.

No problem. I thought I mentioned it timed out in about 5 seconds These days I don't remember much
Yeah, I haven't looked at Vorbeth's script, so I don't know which screen he launches it from. With mine for the 701, you can be when the tab is running normal. No difference in the end result though
Happy Hunting!

One last question - do I have to install Clockwork Recovery for re-flashing the stock images or is it just a case of renaming it update. zip and putting it on an SD Card? Any chance you can point me in the right direction of the most recent/stable build? Is it easy to install?
Thanks again.

Well, this is a trouble spot.
If you wish to install a custom rom, then you will need to install CWM. The most recent version.
If you want to try your luck at installing a stock rom, my opinion, is to leave the stock recovery inplace. I haven't had luck in installing stock update.zips, as Acer has made them very specific. So I can't be much help to you in that.
However, you can always flash back to CWM or a stock JB recovery pretty easy. Personally, unless you plan on flashing a custom, I would just leave the stock recovery.

Sometimes "leaked" update appear here in the forums. They are unofficial. And you never know if they improve things, or make things worse. So be careful.

So, just for future reference, how would I go about re-flashing the stock image? I'm assuming it's saved on the tablet in a separate partition?
I've decided to stick with the stock rooted ROM but would like to know how to re-flash for when Key Lime Pie and future updates are released.
And, seeing as how you haven't steered me wrong so far, I though I'd pick your brains one last time.
Hope you don't mind!
