Broken recovery after 4.3 update - Nexus 7 Q&A, Help & Troubleshooting

I sideloaded the 4.3 update on my Nexus 7. The update went fine, but afterward I used ADB to reboot to recovery because I wanted to re-root it. When I boot into recovery the screen shows the Android lying on its back with an exclamation mark, and fastboot can't find the device. How can I fix my recovery? I did flash recovery when I updated to 4.3.
Thanks

After posting this I tried booting with Vol- held down. It worked, recovery behaved as normal and I was able to use fastboot to flash TWRP.

Unblock, root, CWM

Hi
I used this toolkit: http://forum.xda-developers.com/showthread.php?t=1809195
Bootloader is unlocked, tablet is rooted. CWM installed, but I cant turn on recovery when I'm in bootloader. Author says that I should rename two files - done (both have "-old" in the end).
I can restart in recovery mode when I'm in Android and using RomManager.
What is wrong?

There's a known issue with the recovery option in the bootkoader.
To fix it, while in fast boot mode, attached your device to your computer and then select recovery. Otherwise just select from adb or an app.

Having problems with CWM recovery. Any suggestions?

I used the Nexus 7 toolkit to flash the latest CWM recovery. If I boot into fastboot and choose recovery mode it just hangs on the Google boot animation. I can boot to it from the toolkit though. Anyone else experience this/know what I did wrong?

You need to have a USB cable connected to the Nexus 7, and if you're in fastboot it'll load into recovery. Known bug
Wrong section dude but as said before known bug

It's a problem with the boot loader. For now you will need to be plugged into a computer to go into recovery. It doesn't even have to have drivers or anything installed.
Plug in tablet into computer
Use power and volume buttons to get into recovery
And no, this problem won't be fixed by flashing twrp because it deals with the boot loader.
Just boot to recovery from Rom manager or similar.
I can confirm that quick boot does work to get you into recovery.

Same problem
I've read in other threads that deleting the stock recovery, or modifying it's filename, will fix this problem. Does anyone know if this is true? I can boot recovery through Rom manager or through the power menu. The only worry I have is if I ever get stuck in a bootloop, or brick. It is good to know about the usb trick to load CWM, thanks for that.
Flash TWRP, and use an app like quick boot to reboot into recovery.

I use TWRP and boot to recovery through the roms power menu. I've been very happy with TWRP though, I use a recovery because of stability and performance. I could really care less if it's touch or if it has themes, so when I recommend TWRP it's because I've been using it so long on my transformer prime and nexus 7 and it has done nothing but work exactly like it should.

Weird because today I tried to get into CWR for the first time since I rooted, and it wouldn't work. I got the red ! triangle [sticking out of the green robot].
I plugged it into my laptop.. [and btw I was holding vol UP/DOWN, press power, in the bootloader then selecting 'Recovery' then <Power>] and this time it showed the "Google" and the unlocked lock.. but then booted into the Android OS.
So I flash TWRP [using Ubuntu, and $ fastboot install recovery {TWRP-filename.img}. And what do you know. It booted perfectly into recovery.
So how do you explain that?

The only possible ways to boot into recovery from a working system partition is by either using an app that reboots for you/terminal command.
To reboot from bootloader/button combination you need to have a USB connection otherwise it will freeze at the Google logo. This is bootloader related and not recovery related as any recovery (stock/cwm/twrp) show the same behavior.
You can try fully powering off the tablet and try booting by button combo and you will see it freezes. Using the power adapter will completely freeze your bootloader if you try, so you require a USB connection to a computer to get into recovery.
For me to boot into recovery , I have to use the tool kit all the time. Is that what everyone is doing??? Because every time I go to fastboot and choose recovery (with my N7 plugged on the usb) I get the Android with the exclamation point.

can't get into Clockworkmod recovery

Hi,
I was trying to root my nexus 4 using this tutorial. I got to the part where I needed to get into recovery, I hold down both the volume keys and the power button. I got into fastboot mode and selected 'Recovery mode' which is supposed to launch Clockworkmod, am I right? right after I hit the power button to get into recovery a lying bot with a red triangle and an exclamation mark inside it appeared. I let the device to lay down like this for a little bit and it simply rebooted to it's normal state.
When I installed Clockwordmod it came up just fine the first time so I have no clue of what went wrong..
My boot loader is unlocked and I can see that while in fastboot mode.
Any kind of help is appreciated!

Did you flash recovery in fastboot or with a Toolkit?
In fastboot : fastboot flash recovery recovery-touch-mako.img. recovery-touch-mako is what i renamed the CWM file. Don`t add .img at the end of the name, just recovery-touch-mako or whatever you name it.
I think that you just booted CWM.
The droid with red triangle ils the default recovery. You can flash CWM by typing this : fastboot flash recovery recovery.img
Just rename the cwm image in recovery.img and drag it to the ADB/FASTBOOT folder.
I hope it'll help you

But I've already flashed it and booted into it for the first time. I forgot to tell you that I have a Mac.

You can try to flash it again with fastboot.
It seems that this is a known issue. Here's a tutorial to force flash a custom recovery but it only work on Windows :

JWR66Y Update Recovery No Command

I used the OTA recovery to update to JWR66Y, and this worked correctly. I flashed the update using clockworkmod, then clockworkmod asked if I wanted to also flash the recovery part of the update and I did. Now the phone will not boot into recovery mode. It now says no command with the exposed android and an exclamation rather than any recovery option. I attempted to use fastboot to reflash clockworkmod but the phone doesnt show up in adb devices after the adb reboot bootloader command, and when I use the fastboot flash recovery recoveryxxxx.IMG command, it just says waiting for device and nothing happens.
Anyone have any ideas? My apologies if this has already been covered but I did not find it trying to search.

This is the stock recovery which includes now the "no command". To access the menu of this stock recovery press power then press volume up while you keep pressing power.
Good luck.

Install the Universal Naked drivers then adb/fastboot will work.
You had the right idea.
Is there a Linux fix for this issue, or do I need to bite the bullet and do a windows install, eek.

Reflashing the recovery and root.zip should work

What your seeing is actually stock recovery, I know people tend to get worried when they see the android with the exclamation mark. You can access the stock recovery commands by pressing volume up and the power button at the same time.
You probably want to flash recovery though. Assuming you are already unlocked and have fastboot drivers etc, you need to download the latest image of your desired recovery and flash using fastboot with the following command:
fastboot devices (to check the device is even connected)
fastboot flash recovery <filename>
It should flash successfully. All you need to do now is get the latest supersu zip and flash through recovery.
