[G 2014 Q&A, Help & Troubleshooting] cxxxx:
Hi there,

tl;dr:

Basically, my problem seems to be, that any write-operation on my filesytems is refused:

I found threads about the same problem on Moto G 2013, where "Philz Recovery" was able to fix the partitioning and filesystems, but it seems that this does not exist vor Moto G 2014. And I don't even get any other than stock-recovery working.

TWRP site states: "Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. " But I could not find any key combo to enter the recovery I just flashed (at least fastboot tells me so) Using "fastboot boot recovery.img" just shows a shortly flickering Motorola-logo every 10 seconds or so.

I am having severe issues with my Moto G (2014).

I found some reports of similar issues, but no solution described worked, and it seems I am the only one experiencing this on a stock device.

First some facts:

Device in use since 2 months

Encyption activated about a month ago, no problems

Yesterday, I used screen pinning feature to let my son play a game.

While he was playing, the battery drained until the device shut down.

I connected the device to a charger

After charging 30%, everything first seems normal, I have to enter my encryption PIN and boot process goes on, showing boot animation.

The problem:

At the point, where it would normally finish, the screen just gets black (while still being lit up). Nothing more will happen. The device will remain in this state forever or until the battery is completely drained again.

I first tried using the official methods for (factory) reset described on Motorolas website, they did not work (I am not allowed to post links here yet, google "/prod_answer_detail/a_id/99825/p/30,6720,9151" will show the URL)

Pressing 7-8 seconds restarts the phone, same situation.

Pressing 120 seconds restarts the phone several times, still not working.

I wanted to perform a factory reset, but starting recovery from bootloader only displayed "Boot Up Failed". Choosing "factory" or "bp tools" just started normal boot process. Barcodes seems to work, it shows barcodes.

So next step was unlocking the device to install TWRP. Fastboot displayed no errors, but then not TWRP, but normal recovery starts. Well, better than "Boot Up Failed".

When now performing a factory reset, this is displayed:

-- Wiping data...
Formatting /data...
E:
blkdiscard on partition /dev/block/pla
form/msm_sdcc.1/by-name/userdata failed
E:
blkdiscard on partition /dev/block/pla
form/msm_sdcc.1/by-name/cache failed
-- Wiping clogo...
Data wipe complete

Obviously, the partitions are untouched (or not there?), and the problem remains.

I also tried to erase cache and userdata using fastboot, there are no error messages, but after rebooting, I am still asked for encryption PIN, so it's basically the same.

I then tried to use adb sideload to flash cm12 nightly. But the device complains that the signature verification failed.

Now, I am not even able to lock the device again, while fastboot states, it would have succeeded.

I wanted to reinstall stock images as described on thetechrism.com (Google: restore-moto-g-2and-generation-2014-stock-lock-bootloader) but I have problems downloading as I only have mobile internet connection at this moment and the download from filefactory stopped two times at 200 MB and I have only about 1 GB traffic for the rest of the month.

I am stuck here, and getting desperate. Did my device brick itself?

I have CM12 and TWRP here, but just cannot get it flashed. This would be my preferred solution, but a reliable source for stock images would also be very nice.

Did anyone experience similar problems when the battery completely drained with a pinned app on an encrypted device?

Thanks in advance for any hint.

Regards
