Won't boot to recovery

Either from the bootloader or from the Nexus 7 Toolkit, this stupid thing won't boot to recovery. I flashed from CM10.1 to cm10 after wiping cache and dalvik...now I cannot get to recovery. System boots after going back to stock and even after the CWM flash, but recovery seems to be non-existent. Using the toolkit mentioned I flashed CWM, and I cannot boot to this.

Does adb reboot recovery work

Try downloading ROM Manager from the play store. It will install recovery CMW for you and then you can boot to it. If you are trying to boot directory to recovery using the key press it will not work unless you have the tab plugged into a computer.. the N7 is funny that way.

Have you tried upgrading the bootloader to 4.31? That fixed my problem.

I've already done the upgrade to Android 4.2 when I was on stock. CWM I had from the Nexus 7 Toolkit. Even when I boot to custom recovery via that it just skips over it. When I had CWM installed I could boot to recovery via the reboot menu though so I dunno what the issue is.

What version of CWM did you flash? Perhaps try downloading CWM 6.0.1.9 and flashing it via fastboot
Code:
fastboot flash recovery recovery-clockwork-touch-6.0.1.9-grouper.img

I don't think I need to do all that. Do I need to re-lock the bootloader, flash stock, unlock and flash CWM again or something? Trying to figure out why this device is such a pain in the ass. Even from the bootloader I can't boot to recovery after flashing it!!!

So how do I do this? My bootloader is version 3.34.

Pretty sure I bricked it. Just says booting failed. Friggin overmarketed P.O.S.
Anyone want to buy this?

Dang man calm down before you stroke out. Unless you did something seriously stupid it's not bricked.
And your ROM/flashing problems have nothing to do with the device itself.
Instead of rants, more details would help get you better answers.

It's booting now. Somehow flashing the stock ROM while locked soft bricks it.
So back to the drawing board, how do I get CWM back on here? This whole "adb push fastboot" yaddayadda is Greek to me.

Personally, I'd just flash them fastboot but that's my personal choice. Then flash the ROM, then GApps, then wipe cache/dalvik and voila - PA 4.3

It looks like it is not reading the directory with "ls", a recovery reflash should fix that.

Ok, download the zip files from that thread, on TWRP go to ADB Sideload, on your PC do "adb sideload [zip file here]".
Replace the "[zip file here]" to those zip files so you need to flash the bootloader and radio first so you replace that with the name of the zip file which is in the same directory on your PC where you have set the CMD to read from.
Repeat for the rom and Gapps, of course when you get off ADB sideload wipe the device.

[Q] Recovery issues after OTA update to 4.3

I was on stock 4.2.2 with TWRP installed and I took the OTA to 4.3. Now whenever I try and access my recovery it dispays the Android mascot lying on its back, chest open with a red triangle with an exclamation mark above. I tried flashing TWRP 2.6 via fastboot twice but I still get the same error. How can I fix this? Thank you!

What Fastboot command did you do?, toolkits can't help on 4.3.
The android getting operated on is a security feature so criminals cannot get your data, it is Volume up and power to access the stock recovery on that screen.
Sent from my Nexus 4 using Tapatalk 4

Same exact situation. Stock 4.2.2 with TWRP installed (version 2.6) and then did the OTA. Losing TWRP and root in this situation is normal. I also could not reinstall TWRP the normal fastboot way, and then I saw the following on several forums, and it installed jut fine:
fastboot-windows -c "lge.kcal=0|0|0|x" flash recovery recovery.img

I managed to fix this after trying a variety of things. All I had to do was rename the downloaded TWRP file and flash using "fastboot flash recovery twrp.img" and it worked flawlessly.

Rooting your device running 4.3 by booting a unsecure 4.2.2 kernel?, not really what I had in mind and not really recommended what so ever...

Nexus 7 LTE factory image

when i unlock and root my device (Nexus 7 with LTE) how can i get back to unroot and lock
will be a factory image next time

You don't need an image to lock the device. If you want to go back to stock unrooted, you can fastboot boot recovery and then backup all partitions prior to rooting it after the unlock. Then you can do a regular fastboot flash to flash recovery and flash the superuser zip. Or wait for a factory image as I think one will be along eventually.
Sent from my One using Tapatalk 4

Easiest way is to:
fastboot OEM lock
fastboot OEM unlock
fastboot OEM lock
Unlocking will wipe all data, including root so you'll be stock. Then relock the bootloader.

Nope. Unlocking does not touch root. Root is in the system partition and most people with root have a custom recovery. Unlocking only does a true factory reset (wipe the data and cache partition which includes sdcard). This won't work to remove root.

Sent from my Nexus 4 using xda app-developers app

You don't have to unroot. Just download and flash TWRP 2.6.3.2. On that build, they fixed the issues of 4.4 ROMS incorrectly flashing. Using it myself with no problems. Its in Original Android Development if I'm not mistaken

Flashing 4.4 Factory Image issues
Currently on my Nexus 4.
Android 4.3 Unlocked and Rooted

Using ClockWorkMod Recovery v6.0.4.3, when trying to flash the 4.4 factory image .zip file on the SD Card I keep getting an "Installation Aborted" error after "Installing update..." step and the red Triangle on the android figure.
When attempting to sideload using stock recovery, getting a "Signature Verification Failed"
Any Suggestions? Thanks

I will chime in on this one. I too have had constant failures with TWRP trying to flash ROMs lately. I'm running 2.6.3.3 and everything results in failure. I've tried the unchecking of system mount, multiple downloads with verified MD5s, sideloads, etc. Nothing is working.

next time you flash, after it fails, boot into the bootloader from the recovery. then, from the bootloader, go into the recovery again and flash.

I won't be able to experiment for a couple of weeks. I do know that I've wiped my phone four times or more in the last week with the 4.3 and 4.4 factory images and either manually or using one of the tool kits have added TWRP custom recovery and rooted the phone. Each time trying to flash a ROM it would result in a failure.
Next time I get the chance, I'll give your suggestion a shot and let you know. Are there logs I can capture that might prove useful?

So essentially I've done that with each factory image installed, correct? I'll have to read up on ADB and Fastboot to get the commands to remove the existing recovery. Will be a good way to kill some time (such the life I lead, being envious is not good for your soul)...

no, you just flashed the next version of the recovery over the last. occasionally, something doesnt want to update in the partition, so clearing the previous recovery before flashing the new one will take car of it.

OK that confuses me. If using fastboot to place a new boot loader, radio, recovery and ROM are onto the phone and I have to 'fastboot flash recovery recovery.img' to replace the stock recovery that doesn't wipe out the stock recovery? Fabulous sentence structure.
