[Khaba]

If the flash doesn't work, will erom flash be the next step?

don't start messing arround with the EROM or GDFS
download these files:
-W810_R4EA031_MAIN_GENERIC_HN_RED49
-W810_R4ED001_FS_AMERICA_1_RED49
-W810_CDA102555_106_R2A_Generic_AMERICA_1

and flash your phone, it should be working fine
