But same problem by original flasher IMAGE Download Software - IDT_V2.0.0.9 (error 15)

I used both of them before and worked.
According to these, can not we even solve the new versions?

Downgrade not work not at all.

**.:hack3r2k:.** · 12-03-2018, 20:54

Then can use HUAWEI WORLDWIDE UNLOCK + FRP + BOOTLOADER CODES BY IMEI

Pufi164 · 12-03-2018, 22:11

Work 100% ?
Downgrade to android 7, or board software?

stylius · 12-03-2018, 23:02

So no way dongrade without bootloader code? Custumer pay me 15 eur for phone servise

Pufi164 · 12-04-2018, 00:03

But they pay for it, maybe for Mate 10 unlock + imei ~ 50 euro.
It's worth buying the bootloader code.

(If that works)

15eur is too less for Android 8 series. You must ask 40e at least.
