2.3.4 Root - Nexus S General

Hi guys,
Whats the proper way to Root the Nexus on 2.3.4, my bootloader is unlocked but can't seem to get some of the methods working, if someone can please point me in the right direction I'd appreciate it,
Regards.

There are countless root guides here already, just flash the zip file in CWM.

Yer I've tried them all but keep getting E:signiture verification failure, installation aborted. I'm on 2.3.4 I9020 XKD1 GRJ22.

You did flash CWM recovery first right?

You are probably confusing ClockworkMod recovery (CWM) with the stock recovery. They are different. CWM allows you to flash unsigned zip files, the stock recovery doesn't, hence you got that error.
Follow the stickied rooting guide for your phone carefully, it's not hard at all, don't be afraid.

Hi mate, thanks.
All is working now

Have you flashed CWM recovery via ODIN, and installed update.zip on SD card.
If not search CWM recovery here on XDA, there's plenty of posts to get you on the right track.

Recovery image verification failed

I'm trying to flash update.zip on my HTC Magic running 1.5...hoping to be able to upgrade...but the installation is aborted with the message "recovery image verification failed." Should I find a new "update.zip" that is signed? I'm a newbie at this so please share any advice using simple stepwise language please.

What are you trying to flash? And in what recovery?

CleanMagic 5.0.1
I was trying to flash CleanMagic 5.0.1 A2SD/ML/POWERCONTROL as per the instructions I found at http://forum.xda-developers.com/showthread.php?t=810471. After downloading it, I changed the file name to update.zip and then placed it on a fresh sdcard. But no such luck!
I get the idea that it is indeed possible to upgrade from Android 1.5 to something better, but frankly, I'm completely baffled by the enormous variety of instructions for upgrading and frightened by all the warnings about bricking my phone. Consequently, it would be helpful if someone can either guide me through the process or simply tell me that it's way too complicated for anyone other than a smartphone engineer.

Recovery???
Actually, I'm not sure what recovery I'm using. Perhaps I haven't successfully loaded one although I followed a half-dozen instructions including SDK/ADB and Goldcard, and downloaded several recovery images. However, I'm not sure whether or not I was successful. Sorry for my ignorance but perhaps you can understand why I'm pulling my hair out about this!!!

[SOLVED] Can't update

So I'm trying to install the Gingerbread update on my old rooted Evo, which is now my dads.
And every time it gives me:
E:Failed to verify whole-file signature
E:signature verification failed
Installation Aborted.
I have toggled the signature verification already, still didn't work.
I even tried going to amon ra, and still no.
Running CMR 3.0.0.5
Are you rooted still or not? Lol
No need to unroot! Maybe a bad download? Try downloading again. You will need to update his radio/wimax to flash the GB roms.
Update the radios first. Rename the zip to PC36IMG.zip and flash from hboot. Place on root of sdcard and power off phone. Hold power and volume down to get into bootloader and follow directions on screen. After you update the radios flash rom normally in recovery.

If you are trying to install the OTA GB update, then you need to replace CWM recovery with the stock recovery first.

Do NOT accept the OTA or you will be stuck without root!!!! You have been warned. Just check my post above.

Little bit confused

I've been looking at the threads but so far I don't believe there's one that tells you what to do if you've actually installed the official OTA update?
I.e. I have an rooted 2.3.4 GT-I9023 with an unlocked bootloader. With no clockwork or anything, as to be honest the last time I used it (on my old HTC DHD) it made my phone unstable (the phone would sometimes boot up of its own accord and stop at the clockwork screen).
Does anyone know how to re-root the NS after it's installed the official OTA update without clockwork?
Thanks
Edit: Downloading the OTA update won't relock the boot-loader will it?

You cannot get root back without a custom recovery. OTA will not relock the bootloader, you'll just lose root and custom recovery.
You need to flash custom recovery using fastboot, then flash superuser to get root back. There are plenty of guides in the stickies describing the process.
Ok, so i'm updated to 2.3.6 but of course have lost root (never had CWM to begin with on this phone). Anyone know where I can DL CWM (i'm assuming it needs to be flashed via platform-tools directory in the android sdk per normal) and the latest su file?
EDIT: nvm, I found the latest CWM and successful flashed (my method was correct). However I've not been able to find the latest superuser.zip to flash yet. Also, I don't know why ppl say to use the market as I don't see how that method can work. I've already got superuser installed from before I updated but that doesn't help me get root. Only flashing the zip from recovery (as I understand it) would. Which renders the market useless in this regard.
/confused
The superuser app checks to see if you have the latest superuser binary and will download and instalk it. Or download superuser from within rom manager.

Ok..the binary update fails (because i don't have root) so it's chicken and egg as far as I can tell.
You where already told. Flash custom recovery via fastboot. Boot into it and flash su.zip Same way it was done prior to update to the ota. Same as it always was and will be.

Turn off signature verification in CWM and try again.

Turns out that CWM got overwritten by stock android recovery. Re-flashing CWM and then flashing su did the trick. I'm rooted once more!
Thanks for your help kind sir!
Curious as to how to make CWM stick for next time tho *shrug*

You're welcome.
If you stick with a stock ROM then recovery will reflash every time you reboot. To prevent this you can go to system>etc, and change the file install-recovery.init to something else like install-recovery.init.bak.

[Q] Can't flash stock rom in TWRP

I am looking help from someone who knows TWRP. My phone accidentally did an update and now it just boots into TWRP v2.6.3.2. I am new to this stuff but through learnings I have pushed the stock firmware found on this site (I am in Canada and with Telus) using adb push through command prompt. However when i go to install, it fails. I have also tried Rogers and Bell. Nothing works. I don't understand what is wrong?
What I see is:
E: storage partition '//TWRP/BACKUPS/018bf7ce0f4c6fa0' not found
Installing '/sdcard/TelusD803T10B_00.zip
Checking for MD5 file ...
Skipping MD5 check: no MD5 file found.
Verifying zip signature ...
E:Zip signature verification failed: 1
Error flashing zip '/sdcard/TelusD803T10B_00.zip
Can anyone please tell me what is going on here and what is wrong? I would really appreciate it. The phone is new and useless to me right now as is .... thank you
Did you did an OTA update while on custom ROM? have you tried other recovery? I had trouble flashing with TWRP too. Im using Philz Touch atm and it works great for me.

All I did was accept an update when prompted but didn't pay attention and when the phone rebooted it went into twrp. I had no idea what twrp was. through learning about it i got the stock roms off this website and pushed it on to the phone and tried to install but it just fails for some reason. i don't know what more i can do.
Follow the"back to stock threads" you cant accept ota's when rooted
Sent from my LG-D800 using Tapatalk
I would follow the above comment and follow the step by step guide how to get back to stock when you accidentally got OTA when rooted. Just follow the steps carefully and you'll be fine.Good luck
Have you tried this?
Just untick Zip File Signature when prompting to flash zip.That might work
