SOLVED Broken Recovery after root

Hi people,
I have a bit of a problem here
Recently updated my Nexus S i9020t (unlocked uk version) to 4.0.3, all done no hassle and working fine.
Then I rooted the device following the instructions on nexushacks .com, including flashing TWRP recovery and superuser.
Again, all fine no hassle.
HOWEVER now, whenever I try to boot into recovery, i see a belly up android with a big exclamation mark
Any ideas as to how to fix this, ie re-install stock recovery?
Much appreciated in advance,
All the best

if you still have root just download rom manager and install recovery from there.

Hi Camalus,
I already tried installing clockworkmod recovery from rom manager, unfortunately the issue persists (same deal, android belly up with exclamation)

Is Root working? You can test this by using terminal emulator and typing in "su".
If it is, rename /etc/install-recovery.sh to something else (ie. /etc/install-recovery.sh.bak). This will stop stock recovery installing each boot. After this, flashing CWM or TWRP again will keep it there.

Job Done
Hi Harbb,
Thanks an absolute million, I did as you suggested and then flashed an old version of CWM recovery.
Result: SUCCESS!
Awesome job done, nice one bro

Flash the new one, save you trouble down the track. Also remember to rename that file i said so stock doesn't replace recovery
And of course you're welcome.

Hi Harbb,
Can I flash the new version of CWM recovery through ROM manager, or would it be advisable to do it manually, with fastboot (as I did successfully just now)?
Also, I have renamed install-recovery.sh to install-recovery.sh.bak just as you suggested.
Are there any other files I need to rename in order to ensure recovery works as it's supposed to, or should that be ok now?
Once again, thanks for your help

That's all you need to rename. I'd generally just advise wiping/flashing manually, ROM Manager should be fine for recovery since it doesn't actually reboot into recovery and execute commands.

[Q] I messed it all up in nexus s!

First of all,
I updated to 4.0.3
then i would like to root my phone..
I used a guide found on the nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/ and then i installed rom manager free from market and i tried flashing cwm recovery inside rom manager.
But rom manager was fc and i decided to google it to find an other way to install cwm recovery.
Then i found this guide nexusshacks.com/nexus-s-hacks/how-to-force-your-nexus-s-into-clockworkmod-recovery/ and i followed this exactly, hoping that it could be easy to flash the new 4.0.3 rom again.
When i try to open bootloader mode and select recovery a sparking android is showing up an then only the lights from the touch keys are glowing.!
When i press either (Vol- and Power) or Power Clockwork Mod recovery shows up and when i try to install zip from sd it shows status 7 installation aborted. I searched forums that proposed to wipe all data and dalwik data.
I did all these and also status7 shows up every time i try to flash a rom.
I ask for your help!!!

updated your cwm recovery to 5.x.x.x. and dont expect help or no one will help, ask for help instead.

you are right i wrote by mistake.

I suggest you to download the stock gingerbread for your model from Rom Manager and install it as update.zip. That will unroot your phone. So root it again and try flashing new roms (cm9 or ICS). You should flash kernel after flashing the rom.

Hard Stock

Hi everyone,
I'm kind in the middle of a big trouble.
I receive my first android phone last week and i tried to install a custom rom without well knowing the subject (i used to jailbreak my iphone)
I have a recovery mod that's can't mount the SD partition.
I tried to reflash the orignial recovery mod and relock the bootloader to try a reinsertion of the ROM by the RUU, the phone is not recognized.
Any idea ?
Thanks a lot.
Louis.

Maybe you could Flash a proper recovery tool via fastboot.
I have clockworkmod Touch recovery. That works like a charm.
When this recovery is installed you can push a Rom via adb to the phone.
Leedroid 2 is a very good Rom. Its a modified stock Rom.

Going to root, am I doing it right?

I am on stock 4.0.4 with a locked bootloader. I want to have root with the stock rom, nothing else just root.
So I am gonna use the tool provided here,

I have already installed drivers and have the tool downloaded.
Then I would like to flash the stock google 4.0.4 rom that will let me receive OTA updates. Is this the right file?

I heard there are problems flashing stock rom with CWR if the stock recovery isnt removed? Thats why I dont know if I should flash the stock image.
Is the process of flashing rom with CWR recovery the same as with stock recovery?
My phone is the i9023.
Thanks a bunch in advance.

Sorry should have specified my phone in the OP.

Best way is to do it manually. You can find all of the steps required here. The only difference is that you should be flashing the latest recovery from here and the latest superuser.zip file when flashing with recovery.
Note, unlocking bootloader will cause loss of EVERYTHING on the device that you have put on there (sdcard, apps, data partition, etc).

You suppose thats better to do manually so I will have latest version of recovery and superuser?
And yes I am aware of the data loss waited sometime to finish all my games now I am ready to lose all my app data.

Do it this way. The one click is fine but using Android SDK and going through all that will help you in the long run. This way you know the process in case something goes wrong. It may be confusing at first but worth it. It will teach you a lot more than flashing a one click!
I learnt a lot from this and feel much more experienced and capable because of it. I know I will be able to solve any major issues using Android Debug Bridge (adb).

Okay then I am gonna try the manual way and gonna take out time for it. Now I just need to know what do I flash once I have unlocked bootloader and installed CWR?
I just want the stock google rom and receive OTA if nexus S continues to be supported by google.

You won't need to reinstall the ROM if you are currently on 4.0.4. The ROM stays there as-is. Feel free to do your wipes in recovery and reflash stock 4.0.4 through CWM if you must. You flash CWM to your phone and then superuser through CWM.
Steps:
Setup ADB/fastboot
Bootloader --> fastboot oem unlock --> agree
Bootloader --> fastboot flash recovery recovery.img --> this will give you CWM
Recovery --> flash superuser.zip and, if you must, wipe and reflash ICS (flash su AFTER this if done)
Reboot --> bingo
Also note, with stock ROMs it will replace your current recovery with stock recovery on each boot. If you want to keep CWM, delete /system/etc/flash-recovery.sh when you first boot. You'll have to reflash recovery afterward and it will stick.

Oh I was of the impression that unlocking bootloader wipes everything means it wipes the OS as well. That is nice if it's just data and not the OS, dont think I would reflash it if it's not needed.
Can you explain what you mean by will have to reflash recovery? I will have to do that even if I delete that file on first boot? And whats the drawback if I dont delete that file and stick with stock recovery?

As soon as you boot into stock android it will replace the recovery. So if that file is there on first boot, it will replace it while booting and you will be without CWM (stock instead). After first boot you can delete the file (you can reflash a ROM which has this deleted, or delete it yourself from a stock ROM, or even use adb or a recovery-based file manager to delete the file, then you won't have this problem at all) and it will no longer reflash stock recovery, but you would already have the stock one and need to flash CWM one more time to get it to stick. Easiest way is to just flash CWM and delete it within android imo, saves mounting commands and the such.
No downside really. If you need to flash something for one reason or another you'll just have to reflash CWM before you do so. Once rooted, ROM Manager can do this for you within android anyway.

I had already downloaded and installed the drivers from the one click root thread and my computer shows the android adb thing when I connect my phone with USB debugging.
But as you guys suggested I am gonna do the manual way. So do I just skip the installing driver on computer in the part 1 of this guide?

Because you have a Nexus S with amoled. That's the i9020. The i9023 is SLCD.

He has the i9023 to my knowledge. It is completely normal, though. Bootloader and recovery for i9020 and i9023 series are the same, this can be attributed to the issue with 4.0.3 recovery backlight not turning on.
If fastboot recognises your phone in the bootloader (the fastboot menu), your drivers are installed an working perfectly.

Finally got to the unlock bootloader screen, didnt do it just yet but now I know how to do it.
I must say the guide is a bit outdated, the software has changed quite a bit seems. The most frustrating part was that the fastboot file is actually in the platform tools folder instead of the tools folder which I didnt figure for a while. I will hold off rooting when I have a whole day off because once I lose everything I would be very anxious to get my phone back to normal which will take time.
Thanks for the help harbb, if I have any problem flashing recovery and superuser I will come back for more help.
And yes I have the LCD version i9023.

Btw the guide said the fastboot will be in the tools folder but the tools folder had a read me that "adb has moved to the platform tools folder" this is how I figured to go to that folder and thats where the fastboot file actually was.
Now it says I should put the recovery image in the tools folder so should I do that or put it in the platform tools folder?

In the instructions for the flashing recovery I am not understanding one thing.
6 - Then back on the SNS select Power Off (Reboot also works)
Part 4 - Root
1 - Power ON the SNS
So after flashing recovery I have to reboot? Since I am on stock rom that would bring back the stock recovery so how would I flash superuser then?
If I delete the stock recovery can I still get OTA updates?

fastboot and adb is now in platform tools, that is correct. Easiest way is to put your recovery in there too so you don't have to type in the absolute file path to it, don't put it in tools.
Don't power off or reboot the phone. After you flash recovery go straight into the recovery menu and root, flash custom ROMs, kernels, etc. You can transfer files to flash via the mounts and storage --> mount usb storage menu. After this feel free to reboot.

[GUIDE] Root + CWM Samsung Galaxy Ace Plus S7500 / S7500L - Easy Way

Download CWM Recovery.7z from attachments. Extract Recovery.tar
Download Superuser-3.1.3-arm-signed.7z (or newer from http://androidsu.com/superuser/). Extract Superuser-3.1.3-arm-signed.zip and copy it to your SD card (internal or external).
Put your phone in Download mode. Flash Recovery.tar using Odin.
Put your phone in Recovery mode. Flash Superuser-3.1.3-arm-signed.zip from recovery
Reboot and ready
Thanks developers!

So no need to make kernel un secure?

I didn't needed. The other method posted makes the S7500L keep rebooting into recovery. So, I flashed stock firmware (S7500LVJLH1) with Odin and start over again, but same result.
I'd flashed again stock firmware and just flash recovery with Odin, then just write Superuser from recovery.
I hadn't time to verify if the problem was with boot.tar or with files that are installed in recovery mode by .bat file.

I got my hands on a gt-s7500t yesterday and started xda searching on how to put a custom rom on it. i tried all the methods listed under s7500 to put cwm in it but none worked and whenevr i tried to enter either through pressing vol "+" "-" home and power it never enetred recovery nor it enetered through adb so i moved onto flashing cwm through s7500L guide. so by using http://forum.xda-developers.com/showthread.php?t=1725198 guide, i flased successfully flashed cwm and the phone was stuck in recovery boot loop.
I successfully rooted by through cwm and even installed a custom rom but the dammit phone never came out of the recovery loop, so i went to the next step and downloaded a stock UK vodafone firmware from sam mobile and tried flashing that since australian s-7500t stock rom is unavailable.
Now odin gave a "fail" meesage when it reached to flashing fat.bin, i tried almost 3 different stock roms but same problem. I took the battery out, and tried starting the phone the phone started but no display, so i connected it to samsung kies hoping kies will have a solution, well as it turned out that when i went into emergency firmware recovery, the device screen magically lit up for few seconds and went dark again.
i was baffled so i decided to repeat the process http://forum.xda-developers.com/showthread.php?t=1725198 and flash cwm and boot again. well this time when this completed and phone restarted the phone restarted normally and everything seemed fine, so through adb i went into recovery mode again just to see if all was working fine, but now its the same recovery loop again, have tried wiping the dalvik cache, factory reset and cache reset but nothing happening, HAVENT tried the advanced>recovery reboot> procedure, yet.
now am thinking of two options. first to try install another custom rom and see if that might hellp or since iv got another galaxy ace plus, try to extract the custom s7500T rom out of it somehow, (if u guys can tell me howto, cuz i tried titanium backuo but since it requires root and since i cant get into cwm without using s7500L technique which soft bricks i cant use titanium backup to extract the rom)
Anyone got any idea what to do? is there a pit,bootloader,csc,phone etc files that i can flash through odin rather than flashing a complete package through PDA?
or can i just flash boot.img from a stock rom using PDA and you guys think that will solve the problem>?

This method don't erase your data, just write a custom recovery and add SuperUser app and bin to your system.
The best method to unroot is installing stock firmware package.

I really don't understand how the s7500L rom guys developed them... how did they get out of the boot loop.
I tried replacing the boot.img from the custom ROM with one from a stock rom... nothing.
