CWM bootloop on Nexus 7 HELP - Android Q&A, Help & Troubleshooting

I am stuck in a CWM bootloop. I can install rom and backup from CWM but it just boots back to CWM. If i try to get to bootloader for fastboot mode I get put right back to CWM. Does anybody have any suggestions?

Ah, that thread worked for me too! I didn't realize I could still issue ADB commands while it was booted to CWM. "adb reboot bootloader" was exactly what I needed!

Flashing a recovery over a recovery.

So i have already flashed the CWM recovery onto my Evo 3d, But i have changed my mind and now i want to flash the TWRP recovery. Now i was wondering could i just flash over the CWM recovery with the TWRP recovery or would i have to remove the CWM recovery first? If so how do i remove it. Any help would be very much appreciated.
I had CWM first, and just flashed TWRP right over it. No issues at all

Nope. It will just write the new recovery right over the old one. On my Evo 4G I never had to erase recovery before flashing a new one. I switched between CWM and Amon Ra a couple times. I believe if you did want to erase it though, it can be done in fastboot. 'fastboot erase recovery'. There should be no need for that though. I'm not sure if that command works for us, but it did with the Evo 4G
So like you guys said i flashed the recovery over CWM and it worked perfectly. I only have one more question though...Where is the backup option on TWRP?
EDIT: Nevermind i found it i didn't know what they ment by "Backup partions"
I am unable to do this? I get a 736 error no matter if I try it in MAGLDR113 or CWR recovery. same thing. This happened before and i don't remember how I got it to work.

[Q] Can't enter into recovery

Hi,
I tried to uninstall a add-on by wiping cache and dalvik and re-flashing. For some reason now I cannot enter recovery anymore. Whenever I reboot into recovery I end up in bootloader.
I have turned off fastboot.
Can anyone please help?
Thanks,
Omar.

Aren't you supposed to choose Recovery from the bootloader menu?
I tried that from bootloader as well but it keeps bringing me to bootloader.

Sounds like the recovery needs to be reinstalled.
Try reinstalling a recovery
Or you could boot into the rom and dl quick boot from the market to boot into recovery.

Simply reflash your recovery.
Thanks, how do you reflash the recovery?

via fastboot
download the recovery.img
Code:
fastboot flash recovery nameofyourrecovery.img
done
thanks all for your help. I was able to use flash gui img to flash the recovery and now I am able to go to recovery.
you could also try to reroot it. use the revolutionary tool (www.revolutionary.io) and when the tool finishes, it asks you to install a custom recovery, just press "y" and it will do it automatically.

Hmmm... I am having the same problem today - tried flashing a new splash screen which didn't play nice with my phone. After trying to reboot into recovery, it goes straight to hboot and wants to reflash the image. I can't get into recovery to put the stock image back in.
Any way to fix this without adb, I can't use that at work because my laptop is locked down. Ughhh... gonna be one of those days!
Anyone know of a way to fix this and get back into recovery? If not I'll wait and do it when I get home tonight.
This just happened to me. I used Superwipe before installing a ROM update. When phone rebooted it stuck at bootloader. Can not get into recovery.

Save yourself some trouble and go directly to twrp. You will have less issues when you go to recover.

Go here: http://forum.xda-developers.com/showthread.php?t=1615990 follow the fastboot flash method you should be fine. This should have been posted in Q &A for next time.....
Since you did not unlock it before installing CMW it probably didnt even flash.
Would explain why you cant get in.
As people said use TWRP version 2.2.0.0 (for the newer version you first need the nvflash bootloader) instead. Its better on the prime then CMW.
You can install it via fast boot which is in the android sdk.
PS: CMW backup does not work, the developer doesn't seem to care.
He is probably not holding the volume down key while holding the power key then waiting for the message that says push volume up key to boot into recovery.
You can't boot directly into recovery as far as I'm aware.
The above post didn't explain that very well.

Twrp is better.... if you go the nvflash path.... it is worth it.... just for the peace of mind.

Can't get into Fastboot. Boots into Recovery directly to CWM. Also tried pushing via ADB, TF201 not found.

Tried the custom recovery. It did not work. After installing it via ODIN I tried to boot into recovery but the phone never goes into recovery but just reboots.
I installed the stock recovery via ODIN and it works properly.
k thx for testing i think i need recovery.fstab u can pull that using adb.

As much as I flash via ODIN, CWM, TWRP, etc., I have never used ADB for anything. I will download Android SDK package and get going figuring it out. Bear with me a little while. I'll get back to you. Again, thanks for all your help.
I've tried both ADB and terminal emulator and could not figure out how to pull recovery.fstab. Basically, I cannot find the file. I had to admit, I am a novice when it comes down to ADB and terminal emulator even after the searching and reading about both. I got ADB installed, and it is recognizing my device. I was also able to execute commands but I can't find the file to pull. Am I missing something?

Unable to install CWM on my GT-I9200
Hi Sarath,
I was able to root the phone but was never successful in installing the CWM on my GT-I9200 (India). I get only those 2 red lines when I try to get into CWM but normally everything works fine and no RED lines when booting. Please try to get the CWM working for this phone.
If the phone is stuck without booting or anything happens to the stock ROM then without CWM nothing can be done except taking the Phone to the Service center which is a Pain.
Thank you for working on this....Really appreciate all your work...
i need recovery.fstab.

Hopefully it should work
Use at your own risk as I dont have the Mega
I am not responsible for anything...
I tried the Stock and Custom recovery but nothing worked...
I had to take the phone to the Service Center in Hyderabad. They took 2 days to get it fixed. I got it back in running condition now.
I just rooted it again now. Will wait till I get a backup ROM.
How to Backup the Current ROM?
Could someone help me in backing up the Current ROM? I9200 6.3 Mega India
I have rooted the phone and tried using the ROM Manager Premium 5.2.2.8 and others to back up but it needs the CWM to backup...
If someone has already backed up the ROM then could you provide the link to download....
Thanks..........

Trying to revert to full stock

I am curious to see if anyone knows the possibility of simply booting into TWRP on a new T-Mobile V10 (fastboot boot twrp.img, NOT fastboot flash recovery twrp.img) and pulling the STOCK recovery. If anyone knows if it is possible and/or is willing to be a guinea pig to pull stock recovery I am sure it would be helpful to many in the community.

Yeah, I never flashed TWRP, just booted it to flash SU. So, as per your request, I booted it again and did a backup of only recovery. So this should be stock recovery, since I had never flashed TWRP, hopefully? I don't know how to turn it into an img file tho, but you could restore it in TWRP. Hope it helps.

Glad it helped you! I see people asking for the stock recovery, and there is a link to the img file but it might not be working. At least there's this tho
I have TWRP installed and the phone rooted. Half of my screen died (snow white). So I need to return it. Just so I am clear I can do a factory reset then fastboot boot twrp.img and flash this stock zip and the phone will be back to factory for return correct? Or is there something more to do?

No, the file I posted is only to get stock recovery back. I would suggest using this thread to return your Tmo V10 to complete stock: http://forum.xda-developers.com/showthread.php?t=3241170
Ok thank you. I figured there was more too it. I actually downloaded the file from that thread awhile back. Much appreciated.
