endless loop when installing cyanogenmod - Nexus 7 Q&A, Help & Troubleshooting

Hey,
So I installed Cyanogenmod nightlies from rom manager on my nexus 7 and it downloaded and installed fine, but then the device rebooted and has been stuck on a loop of the cyanogenmod splash screen for a hour or two. What did I do wrong and how can it be fixed?
Thanks

Hold down all three buttons and keep holding them. You should be able to get in to fastboot mode.

Which android version are you on? Did you already unlock the bootloader?

I think you have unlock the bootloader. I might be wrong, but that’s what I did. I unlocked and rooted my N7. Then I flashed a rom, but I was on 4.1.1 then.

dp you have a adb setup or maybe wugs toolkit? Correct me if im wrong but the old bootloader had a bug when manually going into the recovery vai button holding at power up
if you have adb setup try a adb reboot recovery and see if that gets you into clockworkmod/twrp, report back

so i have a new problem....i can boot the nexus 7 into recovery mode, but none of the volume buttons work to change the choice, and the nexus 7 toolkit doesnt see the device
now the screen is going nuts https://dl.dropbox.com/u/3678314/20121017_190402.jpg

[Q] Stuck in boot after flashing PA

I just flashed Paranoid Android on my N7 running 4.1.2, and it's stuck in the boot animation. I've been on this for about 10 minutes now. What should I do?
Go back to recovery, factory reset, wipe caches and reflash

Try long pressing the power button to turn it off and try booting again. Sometimes it hangs on boot after flashing. Especially with certain kernels.
Wow, I'm in the same spot here after flashing PA. Can't get to recovery, PC isn't seeing it either. Been searching all day. Can anyone point us in the right direction? It will be much appreciated.

Nope! I'm slapping myself as with one hand as I type with the other. Is there any method of salvation? *Please note: I rely on toolkits most of the time. Any help is appreciated, as always.

So you fixed it? I updated the bootloader before updating PA to any newer versions. I haven't had bootloops. I followed the DROIDMODDERX video on YouTube when I was on 4.1.1. In the tool kit thread it tells you how to update.

Reboot error related to paths?
I flashed my N7 a few weeks back (using goomanager) with 4.2 JB which worked fine. I then put on gapps and got an endless loop of error messages about trying to configure them. At this point I rebooted to recovery and put back on rooted stock 4.1.1.
I thought I would try PA again this week and the ROM flashes OK, but when I reboot the N7 "hangs" at the boot screen and goes no further. The same thing happens if I try SmoothROM. I can go back to rooted stock OK though.
I notice the paths have been updated as per 4.2 but otherwise things appear the same as before.
Any idea why PA now won't boot?
Thanks

boot loop

My Nexus is stuck in a boot loop.
Trying to load into the ROM will leave me stuck at the Google logo but the unlocked pad(bootloader unlocked). Trying to get into recovery mode will do the same thing. I can temp boot into TWRP using wugs toolkit
I have some very important videos on my Nexus 7 that I would like to recover before flashing the stock ROM
Can anyone tell me the steps to recover when in my position?
Thanks

Custom Recovery Gone?

I just sideloaded the 4.2.2 update and now my recovery mode shows the red triangle error. I can still boot into Android fine and what have you, but TWRP is gone. I tried to factory rest the device in the error screen, but that didn't fix it. Again I can still boot fine, but TWRP is replaced with the red triangle. Any ideas how to fix it? Thanks!

Assuming you're rooted...? Download and install goomanager from the Play store. Open it and tap the menu button (three dots at upper right) and select Install Open Recovery script. It will prompt for confirmation and then download and install TWRP for you.

Use fastboot flash recovery openrecovery-twrp-x.x.x.x-manta.img to get TWRP back?
Wow I completely forgot about this. Exams happened and then I forgot to reply. I was a moron and was trying to flash the Toshiba Thrive TWRP(2.4.1.3) not reading that it was for the Thrive. Flashed 2.4.1.0 manta and it took no problem. Thanks anyhow! I'm going to leave this topic in case anyone else is as dumb as I am(I sure hope not ) so they don't freak out over TWRP disappearing.
Wow your fortunate you didn't do something worse lol. Becareful if you ever use fastboot, a few wrong commands and your fubard

TWRP and I forgot that I shouldn't let it "fix" broken root.
I just used the basic guide on how to flash a factory image of 4.3 in smaller pieces with fastboot, skipping userdata (so I could keep mine), and then sideloaded the two KRT OTA followed by flashing SuperSU 1.75. I did all that in one go, on my second Nexus 7, before booting it the first time.

1st Make sure you are on the latest twrp. 2nd it would be easier just to flash a stock ROM in recovery instead of flashing the factory images.. Is there a particular need for using the factory images or do u just want a working ROM?

hold power button until off, then hold down power and volume down until you get to bootloader. use fastboot to install the system image you want. if you need more guidance, pm me

Most bootloops after updates are solved by powering down and then wiping the cache/dalvik cache. There's no need to flash the system image. In fact, flashing the system image only may not get him out of the bootloop.
If he wants to go back to root, he'll need a custom recovery in any case. I'd recommend flashing a custom recovery, booting into that recovery and wiping cache/dalvik cache.

There were a couple or things that caused this, and it was stuck at the google logo (that's not a Bootloop) . I helped take care of it in the end.
