So I've updated to Calkulins patched latest ROM and still rooted. I also updated to his Wimax IMG. But now I need unroot so I can return the phone before my 30 days is up. I can no longer use recovery to flash back to a previous NAND. Is there any other way to unroot. Maybe reinstall the complete latest RUU..exe? Does anyone have the exe file so I can try. I've only been able to find the zip files but I can't run this because I can no longer run EVO-recovery. Will Sprint even care?...well technically I have to return it to Radio Shack.
