I have had my Z2 Play for half a year, and soon after I got it I unlocked the bootloader with Motorola's official method, installed TWRP, rooted it with Magisk and installed Xposed Framework. I was on Nougat all the time and used it happily. A few months ago it started repeatedly asking to OTA update, but I just ignored the messages. Then one day, I must have accidentally pressed something, because I think it tried to update. I got a message that the update failed or something like that.

The phone gradually got worse after that, randomly rebooting into TWRP. I could somehow get it to boot Android by going to the bootloader and chosing "factory mode" but mostly the modem would not work at all and the phone would not be usable.

Trying to solve it, I decided to flash a whole ROM, hoping to remove all of the damage done by the botchered update. Since I already had unlocked my bootloader and TWRP, I decided to just flash a custom ROM, since I did not know if flashing stock would work with TWRP. I found some of the custom ROMs on XDA, and tried to flash them with TWRP. However, flashing would not work. I got some error code 255. I am attaching a screenshot of the error.

enter image description here

I tried both flashing via the adb sideload method via my Mac and via USB OTG (flash drive) but I got the same result for both.

Having seen this, I decided to try to relock the bootloader and restore stock firmware. I tried following this tutorial. However, that did not seem to work. Here is my fastboot output:

This seemed to do nothing to my device. I wondered if maybe the bootloader was in some sort of locked/unlocked limbo, so I tried to unlock the bootloader again using the key I got from Moto by email. That did not work either.

So I seem to be getting nowhere. There has to be some way to totally wipe everything, to get a fresh start? I do not care if I have to restore stock firmware, stock bootloader, whatever. I just want to be able to at least use my phone somehow. Is my device totally bricked? Is there nothing I can do?

I used adb and fastboot on macOS High Sierra.

  • Did you ask in the forum thread you got the tutorial from? This is a very common Moto flashing issue, as downgrading is not supported and you need a newer version of the stock firmware image (must be the same or newer than installed on your device) and by just glancing over the logs shown, you are likely trying to flash the wrong factory image for your device. I highly suggest going back to XDA and reread the thread and post there. – acejavelin Jul 28 '18 at 14:29
  • @acejavelin Did already, no replies. – Revetahw says Reinstate Monica Jul 28 '18 at 14:57
  • Can you please post the output of fastboot getvar all and mask out IMEI and any other personally identifiable information. – acejavelin Jul 28 '18 at 15:04
  • @acejavelin Alright, I will do it when I get home. – Revetahw says Reinstate Monica Jul 28 '18 at 15:07
  • @acejavelin Done. – Revetahw says Reinstate Monica Jul 28 '18 at 20:16

It seems like your device has upgraded his android version and doesn't let you downgrade. So, the TWRP error 255 it seems like you wanted to flash a 64bit rom on an 32bit recovery. Try to find a stock Oreo image or flash the 64bit twrp. If I find something I will edit this message. P.S. No, your device isn't bricked, there is no OS installed :)
