[Q] Unlocking G510 T8951

[Guest ehsan_zt]

HI,

my friend has a g510 t8951 and I wanted to unlock its boot loader.I tried huawei site but it didn't give me  the unlock code saying "wrong product ID...". I double checked product id sn and imei several times...
SO I was wondering if anyone had the same model and was able to unlock it ?
are all the roms available here for g510, compatible with this model ?

 

Thanks in advance :D
