Unhappy [Q] Huawei P6_U06 B118 lock bootloader


i have Huawei P6_U06 chinese firmware B118 and i need other language ( in this firmware is only few language).

Alot way to flash get error or dont work :/

I can root phone.

If i use cmd and command as here (fastboot oem unlock UUUUUUUUUUUUUUUU) than freeze on ...

If i use vol+ and vol - and power then do factory mode and chinese language - dont work Dload :/

If i use update from sd card in phone up settings/about phone/system update then any chinese error.

On phone recovery cant flash nothing img.

I think phone bootloader is locked.

Can i run Dload other way i think via cmd?
