He sacado esto del foro ruso, se instala por fastboot, dicen que es multilenguaje y que se puede flashear y mantiene la nvram asi que no se pierde el imei, no dicen que versión es supongo que será la última y viene sin root.
Es una buena opción para quien haya briqueado el teléfono, ya no tengo este terminal así que no lo he probado, bajo vuestra responsabilidad.

Multilingual Rom without bugs Remote control and Gallery with intact NVRAM.
Obtained from the 4PDA & XDA-Developer resources I thank.
It is a first effort that will serve to help those who try to change their mobile phone with the brikkato phone.
To be installed with Fastboot after unlocking the bootloader with the following commands:
adb devices
fastboot oem unlock-go
fastboot oem device info
then click on the folder that you have downloaded from the following link and unzipped:
x7_fastboot_tool.bat if you have Win
x7_fastboot_tool.sh if you have Linux
It is not rooted, we are waiting for a TWRP compatible:
