The main problem and why I connected phone to PC is that I lost TWRP after dload firmware upgrade. I can't recover my backup.
Ok. I'll go to the repairshop.
Yes, as also I try AdbDriverInstaller and Huawei Adb Driver. Still nothing.
Now I also admit that phone is charhing slowly even after factory reset. USB voltage tester shows me 5v and 400mA.
Maybe it could be some hardware problem with USB socket?
I'm trying to install drivers for Mate 8. I did it on different PC with Win 10 and 7. With different cables. Try to change or delete drivers for USB hub and etc. In fastboot mode and normal with usb debug and w/o.
Have the the same problem, but didn't find the solution. Try different laptops and different cables. Windows can't recognise my Mate 8 L29 after B320 update cause of the wrong descriptor.
I've the power drain problem too with new build 41816 with tools. No freezes and crashes, but no battery too.
My battery goes to zero after the half day. The most consumptinf application is com.huawei.lcagent in the sytems apps. Try to freeze it with Titanium, but it didn't help a lot.
Installed all the steps but getting the "Tap here to launch TouchFLO". Fiwmware:dt39-UltimateROM-v3.0 [96 DPI, WM6.5 23081] (25th Oct)
What am I doing wrong?
