[Moto E Q&A, Help & Troubleshooting] ivanlabrie:
Hi, I've bought a Moto E XT1025 recently (I'm in Argentina, so it's the dual sim with tv version).

All of a sudden, the phone stopped booting normally.

I tried to reflash a retail image, but could never get it to work.

Every attempt greeted me with an error message, on all commands, except once, when it did accept a few commands but not all of them, and not the one about the partition flash.

I downloaded a retail latinamerican xt1025 friendly image and tried using regular fastboot as well as mfastboot but I couldn't get it to work.

I've read about the phone getting hard bricked after restarting the phone after a failed flash, but only after having done that, so there's not much I can do right now that I know of.

Here's the output of my flash attempts:

So I decided to unlock the bootloader, after asking in a local forum and I got this:

(bootloader) Failed to erase partition
(bootloader) General Unlock failure!
(bootloader) OEM unlock failure! FAILED
(remote failure) finished.
total time: 10.440s

Any ideas?

Phone is no longer under warranty coverage.

Thanks in advance!
