Is my brother's phone unfixable? This is the screen my brother's phone stays at, no matter what action is done, after his phone died and he tried to plug it in. I've seen similar images but most ways to fix it seem to be "flash a new rom" and even then, the images that were posted in that case didn't have those invalid_ver_info notices.

Is my brother's phone dead or can it be fixed, preferably without flashing the rom and possibly doing more harm than good.
The same thing happened to a friend of mine and according to him, the following solution worked:


Use the volume buttons to turn the phone off
Switch it on using the power button
If this screen appears again, reboot into fastboot
reset the phone via a windows computer



fastboot devices
fastboot erase userdata
fastboot erase cache
fastboot reboot




If nothing works, play around with the phone and learn something new!!
