Unbrick Mate 20 Lite SNE-LX1 - Testpoint

You can still check it for drivers installed, regardless, license now extended.

After many attempts this is the best I have managed to do. However, the phone does not go into fastboot mode. Only black screen.

I was wrong ?

Please screenshot of device manager. This has to be world 1st, testpoint and adb interface ports visible at the same time... Do you have hisuite installed/reinstalled? According to your screenshot drivers were not installed of fastboot after writing loader...

I bypassed the error copying drivers with dos. However, the problems remain.

Do you have another computer perhaps? This one clearly not well, loader flashes successfully but phone glitches in between modes, maybe you have battery disconnected/not charged? This would be a problem too.

Then the battery is connected and I have another pc that I have configured with hisuite, fast boot driver etc etc. But the license expired and I couldn't try.

Thank you for the support but i think it is a hardware problem. The problem is the same on this pc too

So if I understand correctly, it enters fastboot mode but shortly after returns to testpoint? Or fastboot port doesn't even appear anymore? If you have board software file you can flash it while in testpoint mode, sadly we do not have this file for SNE-

yes the phone always remains in testpoint mode. The screen stays black and I've never seen fastboot mode. After step 6 nothing happens on the phone and in DC Phoenix it is always detected in testpoint

Yes, display remains black even when in fastboot mode after using loader for most devices, but if port of fastboot does not appear then board of mobile is dead
