[Moto G Q&A, Help & Troubleshooting] michalurban:
MORE INFO: I would like to add that my bootloader is 41.19 and that bootloader/fastboot and recovery works ok. Only when I try to start system, it ends at BOOTLOADER UNLOCKED. I tried 4.4.4, 5.0.2 and 5.1 ... and none of them works ... And in TWRP, I can see "Unable to mount /cache" and "Unable to mount /system" ...

Hi, Ive got a problem:

Ive been using the stock DE 4.4.4. ROM + 5.0.2 OTA on my XT1032 fine for about six weeks. Today I wanted to lock it, so I

1) entered "sudo fastboot oem lock begin" (Im on Linux Mint btw)

2) flashed the DE 4.4.4 ... and the phone just doesnt boot to system; there is the WARNING BOOTLOADER UNLOCKED message and thats it.

The bootloader is still unlocked of course. And I dont think the problem is related to the locking ...

These are the commands I used (they are just from the DE 4.4.4 ROM):

sudo fastboot flash partition gpt.bin
sudo fastboot flash motoboot motoboot.img
sudo fastboot flash logo logo.bin
sudo fastboot flash boot boot.img
sudo fastboot flash recovery recovery.img
sudo fastboot flash system system.img_sparsechunk.0
sudo fastboot flash system system.img_sparsechunk.1
sudo fastboot flash system system.img_sparsechunk.2
sudo fastboot flash modem NON-HLOS.bin
sudo fastboot erase modemst1
sudo fastboot erase modemst2
sudo fastboot flash fsg fsg.mbn
sudo fastboot erase cache
sudo fastboot erase userdata
sudo fastboot reboot

And this is the output

And when I try to sideload the OTA phone says "Installation aborted" ...

Im using the same files I used six weeks ago.

I tried EU 4.4.4 but it is not working either - theres only Motorola logo and thats it.

Any suggestions, please?
