In need of some help... I have cwm3, and I put the trulyepic zip on my SD card, so I go into cwm3 and try to flash... it automatically backs up my old ****, and converts to ext4 without me doing anything, then I can't find the trulyepic file that I put on there. So right now, my phone is pretty much stuck. Tried to restore back in cwm3 to no avail, no idea what to do now. I'll turn my phone on and it just sits at the samsung screen.
Follow Step 6 to flash the ROM.
If you mean you forgot what folder you put the ROM zip in, just take your SD card out of your phone and put it in the SD adapter that came with your Epic, plug it into your computer and find the zip. Then put your SD card back and flash.
I have the Epic 4G for Sprint but running firmware Ver 2.1. Would I be able to user this?
Yes, just follow this thread.
