Re: [HOW TO] Return to 100% Stock - All versions!
Hi, I have a HTC EVO 3D (X515M) that the previous owner flashed a custom firmware into it (King Cobra ICS) + Radio firmware.
It has never worked right from day one with a multitude of issues. (Locking up, radio & WiFi failing until reboot, Camera issues, etc).
Currently it's close to useless. It just keeps filling up it's internal flash memory and failing more regardless of continually deleting more and more apps etc.
Can anyone tell me how to get it back to it's original firmware from the factory? I think it was Gingerbread.
From there I can use the normal update option in the settings menu to get it to the proper released Ice-cream Sandwich version (ICS).
I also have an identical phone with the correct firmware if that helps? As in is there a way to copy the firmware out of one phone to put in another?
It's an Australian phone on the Optus network so I'm not too sure about using the firmware listed here as "Sprint"?
Any help appreciated.
