I have an unrooted, unencrypted LG G4 that decided to randomly turn off and not boot up again last night. Upon booting into normal mode, the LG logo appears for a long time (longer than usual) and then disappears. If it is plugged in, Windows will detect it as an "Unrecognized USB device".
I can currently boot into Download Mode where it shows a "Firmware Update" screen. LG Bridge seems to recognize the device in Download Mode but I cannot mount it as a drive or anything. I have tried both Windows 10 and Linux.
I installed adb on my computers but upon running
adb devices it does not seem to detect anything.
Is there a way to recover data from internal storage? I don't care much about the Camera folder or contacts/SMS as those were backed up automatically, but rather the folder I was using to transfer files between PCs.
