Recovery Bootloop - Nexus 9 Q&A, Help & Troubleshooting

Hi
So I was trying to upgrade TRWP and then flash a new ROM. All went well using wugfresh toolkit until...
I selected erase cache/userdata (think I should have gone with format) thinking I better wipe it clean as installing a new ROM. Problem is, although I have successfully installed TWRP 3.1.1-0, it's stuck in an openrecovery script (trying to format the cache). I get the error unable to mount storage and then it just loops back to recovery and tries again.
I can get to a stable screen by pressing power + vol down but ADB commands are not recognised there.
Is there any way to reset TWRP / stop the script from executing?

I literally just did the same thing. From the main bios menu (last picture in your group), select "Factory Reset" and let it finish... Then start over at step 1.
I'm off to hunt for a ROM that doesn't force device encryption....

Factory reset didn't work for me as it was booting right back into the recovery bootloop, but I have just now managed to revert to stock using NRT. Phew.

having a similar problem, but without installing a custom rom, I got it as a Brocken tablet!, i was wondering if there was a way to put twrp back on it and flash a OS onto it!

I tried that: http://forum.xda-developers.com/showthread.php?t=1514088 and nothing.
My computer recognized the ADB and APX mode with naked drives, but nothing I tried worked
I am almost in the same scenario. have you try this?

bear in mind I am not an expert, so not sure if is the right solution for you
Just to let you know that if I am rebooting the device via adb (adb reboot boot loader) I am then able to load my ROM
No work with fastboot...
with ADB... reboot to recovery after all.
apparently it resets every reboot, erasing everything.
apparently I have this same problem: http://forum.xda-developers.com/showthread.php?t=2243009
Well, as long as it still boots into TWRP it is not yet fully bricked/not bricked at all.
Try flashing the Androwook 2.11 Kernel ZIP file, maybe that helps you. Just search "Androwook" here and you'll get a fine site
The ROM is also awesome! I say it's worth a try ;3

Partitions suddenly became inaccessible

Details: E970 (was bought unlocked on ebay and imported)
2 years ago I unlocked bootloader using freegee, put twrp and rooted. Tried several roms. Some time ago switched to CWM and installed Blisspop.
One evening I find it switched off, I try to charge it but it doesn't turn on. goes to Google logo and than suddenly the screen turns off.
1. Tried sideloading blisspop, it said it succeeded, but nothing changed.
2. Tried factory reset, still the same
3. CWM says this at the bottom:

9. ADB push/pull doesn't work.
Help, please

My phone is bricked to the point of no return

Hi Last week I got the bootloader unlock code for my Honor 8 frd l02 Indian and I successfully rooted my phone. Everything thing was fine until I flashed a custom rom with twrp-3.1.1-1-frd but at 80% it got stuck I waited for 5/6 hours but it was still stuck on 80% so I forced rebooted my phone using the power button now I can't factory reset, flash any official custom rom or boot.img files. The first photo is the system booting into recovery mode but its stuck on that even after leaving it for hours and the second photo is twrp saying the zip file is corrupted I know the files are not corrupted because I have checked with Winrar and 7zip after copying the files to sd card and tried with different sd card, no partitions selected for flashing and twrp cannot mount the /data /system and so on. I have even tried with ADB Sideload but got the same problem. I have tried with Odin3_v3.09 but the USB COM Port is not detected but ADB can detected it. I have tried every trick in the book but looks like my phone has been hard bricked to the point of no return. Is there any other way to fix my phone.

(help pls) Mi A3 - TWRP can't go past its logo screen

Hi!
Yesterday, I decided to change my rom, so i wanted to make a backup of my entire phone in TWRP. My current rom (an unofficial android 12 pixelexperience rom) comes with a recovery, so it replaced TWRP the last time i installed it. Like half a year ago, i used twrp (twrp-3.3.1-17-laurel_sprout-Q-mauronofrio) on this device, everything worked just fine. Now I flashed twrp using the usual commands (fastboot flash boot twrp.img), it finished without any errors. Then I force rebooted into recovery, and the TWRP logo screen just stayed on, nothing happened, except that adb started up, and i was able to connect to my phone over adb.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After this, when i rebooted it normally, it went to this TWRP screen. I tried switching the active slots, erasing the current recovery, trying out different versions of TWRP, but none of them worked.
Is there a fix for this? I would like to backup my entire phone with TWRP before changing roms.

I can access recovery after a "Cannot load Android system" but can't sideload a Rom

Hi
My Mi a3 lite showed the "Cannot load Android system. Your data may be corrupt." error.
Bootloader is not unlocked so I can't flash a fastboot rom or unlock it from outside. I can access recovery but the latest recovery rom I can find is V12.0.22.0 and the phone has the v12.0.23.0 so when I try to sideload it via adb it says I can't downgrade the rom and stops.
My goal is, if possible, to recover the phone without losing the data and just as extreme measure reinstall everything from scratch.
I tried the xiaomi tool v2 but it doesn't help because I don't have the Mi Assistant mode.
Is there anything can I do?
Thanks!

Hi, I found this
I entered EDL mode by shorting the pins and flashed the service rom as described in the video. Everything went ok, but now the phone restart with the same message above and I just see that the rom is now 12.0.3.0.
Unfortunately the phone seems not responding to Keypress now, so I can't enter ADB mode and see if I can upgrade to a newer rom.
Any suggestion? Why Do I still receive the same message even after flashing a new rom?
Thanks!
Sergio
did you do data reset?
