N7 only boots into recovery - Nexus 7 Q&A, Help & Troubleshooting

Ok so heres the story. Ubuntu released a version of it self for the N7 and I went to try it out. Works ok kinda sluggish, but I digress.
Went back to stock and it went smooth as butter. Now I went to flash CWM and it flashed like it was supposed to. Now for some reason my tablet only boots into recovery no matter what. I tried to press power and vol down to get into the bootloader and it just boots recovery.
I used Nexus Root Toolkit v1.5.4 to flash the image.

It's stuck in cwm?
Can you reach it via adb?
If so enter "adb reboot fastboot"

Tried that and ADB said there was no device attached. So, I reinstalled my drivers and that worked. Managed to get into fast boot and reflashed stock. I manually flashed cwm and that worked no problem. I'm now back on my own version of cm10.

Changing Bootmode Via Terminal?

My computer is down and TWRP seems stuck in recovery mode? possibly. Every time I try to flash a ROM TWRP just reboots itself. I'm able to backup and restore fine but cannot flash. I'm running dualboot bootloader if that matters.
Is there a way to check what mode it is in via terminal and also change it?
Any help would be greatly appreciated.

I know how to flash via terminal. I need to know of you can change boot mode via terminal. I already tried flashing the recovery over top of it but I still cannot flash a new ROM. (The tablet boots up fine, fyi)

If you can flash twrp 2.1.1, then you can boot into your rom from twrp. It used to have a bug where it would not change bootmode. I believe it is now fixed with v2.1.1.
Hope it helps.

I flashed 2.1.1 with success but still was unable to flash a ROM. To top it off, I clicked the "reset boot loader" option and now my Kindle is stuck on the dual-boot boot loader screen and will not respond or go further....

Yeah it was a stupid move, I was just getting frustrated with it not flashing ROMs all of a sudden and I just started trying random ****. Waiting for my friend and his laptop now.

Type this in terminal emulator:
Su
Oem idme bootmode 4000
FINALLY! Damn, his laptop was being defiant and didn't want to install the fastboot drivers. Was starting to piss me off, but an hour later and I got it going!
I had to run
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
I haven't tried to flash a new ROM yet, I don't even care at this point, happy the Kindle is back up. Now time to try and get ROMs to flash...
OK so I reset my partition to stock, flashed the latest FFF (replacing the dual-boot bootloader) and flashed the latest TWRP 2.1.1 and it still failed to flash ANY ROM. I reverted to TWRP 2.0 again and tried and it didn't fail...yet. It started the flashing process but I'm not sure it'll complete (been flashing for about 5 minutes now and has not completed). Really not sure what the deal is with flash failing. This never happened before.
EDIT-
Nope, goes...

[Q]CWR or TWRP?

I just want to know which recovery should I install...I'm new to the pad game and I just wanted some input...I just rooted my N7 and ready to install a recovery...I'm used to CWR on my sgIII...but I see that TWRP is the new recovery that some guys are installing...also is there problem with boring into recovery from the device? Thanks in advanced...

I prefer cwm touch which you can get from the site. Or you can flash the button version from rommanager
Twrp does work tho, but I've read issues with restoring backups.
Booting into recovery on the device in a way is messed up. The button combo method to enter using the bootloader hangs when not connected to a PC, so there are two options on getting into recovery.
A. Connect to a PC and use bootloader
B. With a working OS, reboot to recovery using an app such as rommanager or goomanager
If you ever flash a rom that won't boot, u need to connect to a PC and boot into recovery via bootloader (button combo).

I use TWRP and had successfully restored now a couple of times. Once was a complete device replacement where I restored the TWRP restore files from my workstation.
How I do my backups to ensure I can restore from a total loss.

Ah, I was curious if this bug still existed or not.
I'd go with CWM, quite stable, easy to use, and you can flash the touch recovery, speeds it up.

Thanks, I read somewhere that if you go into system/ and rename recovery-from-boot.p to recovery-from-boot.bak, fixes the bootloop...can anyone confirm this... thank in advance

Can't boot into recovery with new bootloader and CM10?

Hey all:
I'm running the CM10 nightlies (1022), and I was wondering if anyone else is having trouble rebooting into recovery. Ever since I flashed the 3.41 bootloader with the OTA, my device reboots if it tries to boot into recovery. Any ideas?

there is a good discussion and solution here:
http://forum.xda-developers.com/showthread.php?t=1933591
i tried the method of flashing the 3.34 bootloader and it worked, but i think the method of using CWM 6.0.1.5 sounded better (though i have not tried to prove it)..

Are you "reboot -> recovery" or are you booting into Fastboot, then selecting "Recovery" from the vol +/-?
I flashed this zip: http://forum.xda-developers.com/showthread.php?t=1928915
then flashed CWM touch, and I can boot into recovery from fastboot, or from "reboot -> recovery"
is that what you flashed?
I used the flash all script from the Google developers site, so I flashed using fastboot. As for booting into recovery, this happens when I boot into it from the bootloader and from Cyanogenmod.

ROOTED 4.2.2 won't boot recovery

Just rooted my N7 on 4.2.2 but can't boot into recovery. I just get the "no command" screen. I flashed twrp with the Nexus Root Toolkit and everything seemed to go fine but I can't boot into recovery. Is there another way to flash a custom recover?
Thanks!

you probably booted, not flashed the recovery. fastboot flash it via fastboot with the instructions above. or, to make it even easier, download the goo manager app. you can flash twrp recovery with the app. open the app, press the settings option, press install openrecoveryscript, press yes, then let it do its thing.

Read the download instructions at the bottom. Have you done that step?
The stock recovery will be restored on boot otherwise. It's the same procedure for any recovery (CWM) not just TWRP.

Why can't I boot into custom recovery?

I'm running CM 10.2 and every time I try and boot into recovery, it boots into stock recovery instead of CWM. I've tried booting into it using the menu when you hold the power button and then I've tried holding power+volume down on restart and every time it just goes stock.
Any help/opinions are much appreciated.

Turn off your device, hold all three buttons until you see a menu pop up. Select Recovery and you should get CWM.

Every time I go into recovery, it sends me to the Android with the exclamation point, then I get to stock recovery. Even with the three button.
Looks like you need to flash your recovery again

Yep, and after flash is complete, power-off your phone and boot straight into recovery. There's an install script that needs to complete. If you don't boot straight into CWM, stock recovery will override CWM.
I didn't do that last time, that must be why I can't get there now. Thanks for the heads up!

Well I ran into the same problem where I just get dead Andy. I flashed TWRP from fastboot but for the life of me can't remember how to boot into recovery from there.
Edit
I literally looked for over an hour about how to get into recovery before I posted. Well I found the answer almost immediately after posting, power/Vol+.
So I flashed my recovery again through fastboot, powered up using power/Vol + but still can't get into recovery.
Are you on stock ROM? You may have to remove or rename the recovery install file install-recovery.sh after flashing TWRP... Located in system>etc on stock

Thanks anyway, but after trying to flash with Flashify and that not working I tried an app called recovery tools that fixed my issue.

You could have just installed Rom Manager & flashed the Photon Q recovery then flashed Philz or the latest twrp they are in my goodies.
Oh... I always fast boot the recovery...
