My D855 got stuck in Fastboot mode, i try to get into TWRP, but also got stuck at teamwin screen. I went to Download mode, but then straight direct me back to Fastboot mode..... Now my phone couldn't switch back to adb mode, only stays at LG screen..... What can i do in fastboot mode? I try to do the command to restore the stock recovery, no working at all.....and all errors..... And my pc only can detect the phone when its in Fastboot mode, which is i can't flash stock rom or else..... Is there anything that i can do to get my phone back?
so I had a similar problem. The service said that the phone is not in Ukraine. because it can not do.
But there was no official service to the man who revived all.
Try to find out if he can help remotely.
Shipping to Ukraine for repair will be abnormally expensive.
