I have upgraded to 4.0.3 and its really slow and bugy, so I desided to downgrade, but this is what happens when I try to go into recovery, please help.
Phone is all stock, not rooted or anything...

Yes, this is normal. Your phone is an i9023, the backlight doesn't turn on with new recovery, you can see it if you use a strong torch/lamp at the correct angle, and yes it is all there and functioning (just no backlight).
I believe recovery will give you an error if you try and downgrade though. You'll need to root/unlock bootloader and use CWM before you can do that. You can happily lock the bootloader afterward.
Also, you might be happier with ICS if you do a factory reset, and maybe even reflash ICS. This can solve some problems.
Thank you very much Harbb, any suggestions which way to root is the best and easiest for Nexus S?

I'd go the bootloader method. This gives you full access to the system which will allow you to throw in the su command in /system/bin, or just allows you to install and backup any rom you'd like. Only thing is it is "obviously" unlocked and wipes EVERYTHING but the OS (that is, sdcard and ALL personal data and settings).
Of course you can relock it any time you want though, for warranty purposes. Easiest and most thorough walkthrough (from my limited scouring) is here. Has a video too
Just note, for ICS you want the latest superuser zip, not the one provided.
Thanks guys, will try something now.

My girlfriend just got a Desire S and we're thinking about rooting it and installing a custom ROM.
Before we even think about starting, we have to make a backup image of the phone because if we need to send it back under warranty then they may decline to honour it if it's rooted.
I'm just installing the Android SDK on my machine now with the USB driver.
I can get into the fastboot on her phone with [vol-]+[power] but not really sure what to do from there.
I did a bit of reading about fastboot here and here but they don't really seem to say much about creating a backup image.
How can I do this?

Hello, unfortunately I'm not a fastboot expert, although I don't believe that you'll be able to take a useful backup using this method without an Enginerring bootloader which you don't have and can't get without S-OFF.
You be better off getting S-OFF using AlphaRevx, then rooting (using gingerbreak) and then using installing and using a recovery to perform full backup of your device.
You'll always be able to use an RUU to reflash your original ROM if you needed to restore and return for warranty. Assuming that Alpharevx have made their bootloader change reversible, which I'm sure that they will do soon.

To make a back up image (Nandroid), you'll need to be rooted and S-off first. Any back up that you make will therefor be of an S-offed, rooted phone! What your looking for is the proper RUU for your device. Goto settings - about phone - software information, to find that out.
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.

Long story short, I rooted my phone a long time ago (with the intention of installing a root-access wifi app). Foxfi started to work, so I never went any further than unlocking the bootloader, installing root, and installing superuser.
Since then, I got the OTA update to 4.1. I tried to uninstall the superuser app, but I'm not able to uninstall it. At this point, I would like to simply uninstall super user and maybe re-lock the bootloader.
I've looked around online and found some instructions, but they are generally for ICS or gingerbread. So my first question is if that matters. Secondly, all the instructions refer to flashing a stock ROM, and wiping data. I already have the stock ROM, so I don't know if I just skip certain steps in the process, or what.
My questions are probably pretty basic, I just want to make sure I don't brick anything, or totally reset my phone (if it isn't necessary).
Thanks!

You are stock rooted so flash factory and this will clear your phone to pure stock. To relock bootloader at the end just fastboot oem lock. Your phone will be like it is out of the box. If you choose to unlock again remember that does wipe your SD. There really is no need to lock bootloader unless shipping for warranty reasons.

I'm still a little confused, do I need to download a ROM from that thread? I've never installed a different ROM, so don't I already have a factory ROM?
Also, as a note, I've got a Nexus S 4G from sprint.

You said you "would like to simply uninstall super user and maybe re-lock the bootloader." You have factory but rooted (superuser)
So flash factory which will remove SU and make it as if "out-of-box"
This may make help you more.

Okay, as a newby poster on this forum, I can ask this question here, hopefully someone reads here that can help *smile*.
I've followed the rooting guide for my post JB OTA updated Galaxy S3. My phone is now apparently rooted, I can grant root access to apps and all. I should have a custom recovery installed as well (I chose TWRP since a lot of people seem to choose CWM, and I'm a rebel without a cause), but I'm not sure, since when I booted out of recovery after installing the SU app, I didn't see the "Disable recovery flash" prompt. And I haven't tried to boot into recovery mode yet to verify whether the TWRP version that I installed is still there. Doesn't seem to have affected the resulting root access ability one way or the other, though.
My question is that when I boot my phone normally now, I see an unlocked lock icon, and "CUSTOM". Since I re-flashed the stock boot when I was done, this is a bit disturbing, I didn't expect that. I've read that if I have a custom recovery that I'll see this even if I have stock boot. Is this true? I think that stock boot is a good idea, but am not convinced that I have it. Is there any way to tell if I have a stock boot or not?
A little puzzled, although I definitely like the rooted phone better than the non-rooted one, so thanks much for that.
Just rebooted the phone into TWRP recovery a couple of times this morning, so I guess that I still have the custom recovery installed *smile*. And I'm also assuming that flashing the stock boot at the end of rooting worked, despite the unlocked lock icon and "CUSTOM" when I boot my phone now.
I guess there's no need for a reply here, since I've answered at least part of my own questions. I'm assuming then that I'm seeing "CUSTOM" and the unlocked lock icon when I boot because I have the custom recovery installed, and when I un-root it will go away. I've already set my flash count back to 0, since I wanted to remember to do that while I still had root, in case I un-root to send the phone to Samsung, and forget to do that.
Again, thanks for the guide thread on rooting, very helpful. The only first-time snag was booting into TWRP from Odin mode so I could install the SU app. Eventually figured out how to do that, so when/if I do this again should be much quicker.
Could someone help me? I'm currently rooted on OOS, with TWRP and a custom kernel installed. I'd like to unroot and go back to fully stock (in light of the recent development of SafetyNet and CTS; see TopJohnWu's tweets, cause I am by no means an expert, but he makes it clear this is the end of rooting permanently now). I need help on how to do it without bricking my device, and also a method of transferring as much of my current data as possible (obviously Titanium/Swift Backup is out of the question cause I won't have root access). Thank you very much in advance!

I think you con relock the bootloader/unroot with the msm tool. Dont hold me to that I may be wrong
https://forum.xda-developers.com/oneplus-7-pro/how-to/msm-tool-guac-t3934691
This would be a good place to start.
I have done this many times, firstly, install the lastest version using the full package from OP page, this will get rid of the TWRP for you, then restart in fastboot, in fastboot, run "fastboot oem lock" (or would be relock?), confirm in your mobile, reboot, reinstall the last full package and be happy.
Something like it, I don´t remember exactly, but this is the idea.
Tks and good luck!
