Here a workaround for the ones interested:
1- Make sure MID and CID match, for the developer edition you have it should be:
If they match then you can download a stock nandroid and the firmware here
2- Wipe evertying using TWRP and then restore the nand you´ve downloaded from the link above
3- Reboot your phone into booloader and then flash the firmware
4- I would advise you to clean the cache once you install the firmware in bootloader
5- Do a full factory restore from the bootloader, your phone should reboot by itself afterwards
In case you need it:
In order to flash the firmware you have to type Fastboot oem rebootRUU
in bootloader mode then you will see an HTC grey logo, there you will have to type: fastboot flash zip firmware.zip
. Make sure firmware you've have downloaded is renamed as "firmware.zip" before you do all this. I would recomend to perform this last command twice. To reboot your phone into bootloader type: fastboot reboot-bootloader
, once your phone reboots then type Fastboot erase cache
, perform a full factory restore there and let your phone reboot. After your phone reboots, you should have the latest version installed.
As and advise: be carefull with all this!
