Hola,
Tengo el mismo modelo que tú y comprado del mismo sitio, y si, yo he instalado la última versión de desarrollo del 1 de Junio.
La he instalado con estos pasos sacados de XDA:
Full Restoration to Stock ROM
1. Download latest Official Full ROM from EMUI's site (L02, L12), HuaweiUpdateExtractor and adb.
2. Unzip ROM and open UPDATE.APP with HuaweiUpdateExtractor.
3. Extract SYSTEM.img and RECOVERY.img (delete .header files that HuaweiUpdateExtractor generates you need only .img files) and put them in adb folder.
4. Boot in fastboot and conect to PC.
5. Open cmd.exe from adb folder and type (or copy-paste) the follow commands one by one:
Code:
fastboot devices
Code:
fastboot flash recovery RECOVERY.img
Code:
fastboot flash system SYSTEM.img
6. Put dload folder, you extracted before from Full ROM, with UPDATE.APP to root of your SD.
7. Detach USB cable from phone, turn it off and boot it up with holding all 3 buttons (POWER, VOLUM UP, VOLUME DOWN) untill you see EMUI installation Screen.
This is a full restoration method that means that will lost data, root etc.
You can skip steps 6 and 7 and do local update, instead of 3btns installation, after step 5 so you will not lose data. Related post.
OJO: Ten en cuenta que se te va a quedar como si fuera la versión china y no vas a poder instalar Google Play y sus aplicaciones de primeras, ni se van a sincronizar los contactos, etc...
Lo que hay que hacer para recuperarlo todo es instalar las GAPPS con el multi-tool y ya vuelve todo a la normalidad
