Hi,
I could not update the firmware on this phone, I can not find any C65 firmware anywhere, do you have any idea how to do it, or if there are firmware compatible to install?

Tanks at all

Are you sure its not C654 or C55?

Sorryyyyyyyyyyyy ..... C652 not C65.

The phone is a retail demo version, i've unlocked bootloader and install root and twrp, but if i try to flash one firmware, twrp stop it with error e:unknown command [errno]
Any idea ?

Thanks
