Help!! Flashed wrong rom and now cannot reboot into recovery - Nexus S Q&A, Help & Troubleshooting

I had the stock 4.1.2 rom on my i9020a nexus s. I then wanted to downgrade to 4.0.3. My phone is rooted and i have SU and cwm recovery.
I downloaded the wrong rom (i downloaded 4.0.3 rom for i9020T) and i flashed it. I found out i flashed the wrong rom afterwards.
Now, i can't boot the phone into recovery, i have lost SU and cwm recovery. I've even tried using adb shell -> su and it did not recognize it. When i tried using bootloader into recovery, an android with a red exclamation mark just showed up.
I have even tried to use fastboot to flash recovery and it just gets stuck at 'waiting for device'. I am 99% sure i have all the drivers installed too
Is there a way i can fix this? I tried to flash cwm recovery again but nothing happens.
I have a nandroid backup of the original 4.1.2 stock but i dont know how to restore it if i am not able to boot into recovery. please help!!

Can u get into boot loader mode?

This is my fourth Android device, never had any problems rooting before.
Nexus S GT-9020 (I9020GSMH) on Orange UK
Following this guide http://forum.xda-developers.com/showthread.php?t=895545
Successfully unlocked bootloader
Successfully flashed clockworkmod Recovery 3.0.0.5
Successfully installed SU using su-2.3.6.1-ef-signed.zip (from http://forum.xda-developers.com/showthread.php?t=682828)
The problem is on every boot i go into clockworkmod recovery. On every reboot i go into recovery, except when choosing "Reboot Recovery" when it gets stuck at the Google screen.
I have tried re-locking and unlocking again, which shows no error, but then back into recovery.......
What have I dont wrong?
Please can anyone help
Thanks
You could've flahshed your recovery into boot. Only fix is a nandroid or flash a new rom.

[Q] HELP stuck on google screen after trying to root with superboot

I tried using superboot to root my nexus s, but ended up with having a stuck google screen upon reboot.
Is there anyway I can recover my phone to the original state. I can get into the boot screen by pressing up volume and the power button and I have downloaded an original rom; however, I don't know how to upload this rom
into the phone.
I unlocked the bootloader, and have the android SDK installed. I do have a response when I use the command "fastboot devices"
Is there any possible way to save my phone? Please help, Thanks in advance
is there a recovery image saved under the recovery option?
Hey I'm having the exact same problem as the OP.
I don't have a recovery image saved in recovery, so I tried to flash the latest CWM recovery image through adb, but the device isn't found.
My phone was rooted, then upgraded to 2.3.4, then got 2.3.6 OTA, but lost root. Tried to root with Superboot and now my phone's stuck.
How can I get my phone to work again?

You have to flash CWM using fastboot, not adb.
fastboot flash recovery recovery.img
Once you have the custom recovery flashed you can flash superuser in CWM to get root back or just flash one of the custom ROMs that include superuser.
Yes, I did exactly that.
I really have no idea what I'm doing so I'm extremely grateful for people who do.
Thanks
I am in the same boat as these other chaps. After installing the 2.3.6 OTA update I tried to root with Superboot and now my Nexus S just sits on the Google screen with the open padlock.
I've tried installing CWM recovery, as well as the boot.recovery.img that comes with Superboot, and it seems to install successfully. After rebooting my phone still sits on the Google screen, however.
Am I doing something wrong here (I'd previously rooted with few problems)?
EDIT: I should mention that after flashing the .img I'm trying to boot into recovery - at this point it just sits on the Google screen.
EDIT 2: Never mind, I sorted it. I tried using a different recovery.img (from this thread) and I was then able to get into recovery and restore a backup.

[q] how to boot recovery on ics

I9023 cannot boot recovery after upgrade to ics
Are you rooted??? If yes, you can use rom manager to reflash CWM, other options is to fastboot flash recovery from your computer... Because probably what happened is that you use a stock rom to update and recovery went back to stock, and if nothing of this works please provide more details...

ICS default recovery is not work, you should flash it by youself
use adb
if you can connect thru adb and assuming that you have a valid recovery you can use the following:
"adb reboot recovery"
that should get you to recovery afik this will work with stock or cwm recovery.
If you don't have a valid recovery you will have to flash one (possibly thru adb if you can't get it going any other way)

[Q] Red Triangle, Dead Android

After months of flashing everything in sight on my NS4g, the device appears to have rolled over and died! It started a few days ago, when it rebooted and asked me for a password to decrypt from storage (no password has ever been set). I couldn't get past that screen, so I decided to boot into recovery (TWRP), reinstall ROM (CM10) and gapps and restore data from backup.
No go. It just kept rebooting into recovery. But I was able to connect the phone to the PC and copy files from the phone but could not copy or delete files on the phone from the PC.
I used fastboot, Odin, and one-click-stock to wipe the device and install factory images, but the phone would boot no further than the red triangle-dead android.
Is my phone dead? I searched the forums and couldn't find any solutions other than to do what I have already done.

When you flashed to stock you erased your recovery.. Reconnect to your computer and push a recovery onto your phone and you're good to go..
Unfortunately, when I flashed TWRP and boot.img to the phone using fastboot and attempted to boot into recovery, bootloader reports "No Boot or Recovery Img."

Try the Nexus tool kit and from the bootloader (power and vol. up) select flash to stock (bricked) then in advanced boot temporary recovery to flash the recovery of your choice.. or push a boot image.

Wish I had better news but ... using the Nexus tool kit I was able to boot into TWRP but when trying to flash CM10 and gapps for this phone the flash failed; likewise, I could not flash CM10 and gapps by pushing the files from the PC to the phone. I first did flash to stock (bricked) but that brought me back to the red triangle, dead android.
I am beginning to suspect that the phone internal sdcard is corrupted ... is there a way to test for that?

When you got it to flash to stock did it boot up fully?
Remember that flashing to stock removes custom recoveries and you will need to flash one

No, the phone never did boot up fully. It got to the Google screen with the unlock icon and then to the red triangle, dead Android.

This happened when you tried stock or custom?..
Did it fully boot on stock image?..
The dead android usually shows up when you attempt to boot into recovery and you don't have one... If you try to boot and you loop back to the dead android it usually means you don't have a rom...
Try again to flash to stock, use the toolkit to boot a temporary recovery and flash a custom recovery.. Then make sure you are flashing the correct rom and correct gapps for that rom and for your phone.

I know have a recovery because the tool kit booted into TWRP; furthermore, the tool kit installed a TWRP 2.3 image (prior to installing the tool kit I was on 2.5 so the tool kit did something). From there, I tried to flash CM10 and gapps in the sdcard/download folder, but that failed, with TWRP returning message similar to "error opening ZIP".
I have used Odin to flash the stock image and it did not fully boot, ending at the dead android. Same results for flashing the stock image using fastboot with the phone connected to the PC. Same results with using the Nexus tool kit to flash a stock image (first JB and then, when that didn't boot, ICS). And, after the toolkit booted into temporary recovery (TWRP), I tried to flash (in this order) CM10 plus gapps, JB stock, and ICS, each time with the same results (no full boot, dead android).
I am with you when you say that the dead android means there is no rom, because my efforts to flash any rom, whether stock or custom, don't do anything. To all appearance, the phone contains a bootloader and a recovery and nothing else.
Thanks for your persistence ... any ideas for something else to try?

I'm at a loss.. Try again, maybe there's something missing.. And flash only one at a time and see if it worked (just ROM then reboot) then wipe d+c and flash gapps reboot then wipe flash... Ect... Ect...

I am too. Every method known to me (Odin, fastboot, adb) to flash a ROM, whether custom or stock, has failed to boot. Thanks for hanging with me on this; if you can think of solution I'll be glad to have it. Or if I solve it, I'll post here.

Can't Access TWRP Recovery

Hi guys, I flashed the latest factory image, then flashed the latest TWRP but can access it 1 out of 10 tries.. What am I doing wrong? Is it a faulty replacement phone? Never had this issue with my other nexus 5 (same recovery file but lollipop and not marshmallow) and now I have this problem.. Tried to riflashato the factory image 5 times, boot to recovery without installing but nothing changed.. Thanks in advance!
If you just just flashed TWRP, then booted into Android, then reboot into recovery.. Android will overwrite TWRP with the stock recovery.

This is not really a fix, since to use Flashify one needs to be rooted already.
What I did to work around this was reflash LMY48M. After reflashing that, fastboot correctly boots/flashes twrp.
I've read that the issue arises when trying to boot and/or flash twrp with MRA56K installed, AND the device is connected to USB.
Ok, i got some of problems here, i tryied to root my Nexus 5 with other Android 6 version, it was the first one launched after development version. Now i have MRA58K version.
Problem 1 : I have no stock recovery, i first rooted original version of Marshmallow with CWM and i soft bricked, so no backup, no factory images. Installed MRA58K and there is no stock recovery, thanks god i can use bootloader. I can install TWRP, but i want to install the old recovery, Tell me how to do it.
Problem 2: Actual version of Marshmallow ask me to install a patch, but when installing i got stuck in TWRP, it cant install it (yes, android was rooted, but i installed twrp before root, and the update were before it.)
Thanks.
You can flash a stock ROM using the flash-all file in a command prompt. This will install stock ROM with stock recovery. Make sure the phone has an unlocked bootloader and you should be fine.
Official OTA updates cannot be installed with a custom recovery.
I tryied 3 times to install OS with flash-all. All the problems start after i installed CWM and try to root the phone, but after that, i used a stock rom image that was different build than actually one.
I`m not sure yet who`s fault is.
Any ideas?
I don't recommend using CWM, only TWRP.
After you flash TWRP always boot into it, and since you're flashing a custom recovery I'm going to assume you don't care about OTA's, swipe to allow system to be mounted. TWRP will automatically patch the system to survive android trying to overwrite it. Reboot into TWRP a second time to be safe. TWRP should stick from now on until you flash over it or restore stock system partition.
Yes, now i have TWRP as recovery, but i want to replace it with stock recovery.
Problem is, when i upload stock recovery and try to boot in recovery mode, i got the green dead android with red triangle.
But after TWRP uploading and booting in recovery mode, TWRP is there..
I really don`t know what`s wrong.
Flash stock recovery, select recovery from the fastboot menu, hold the power button and press volume up button.
