and this rom:
the Stock EC05 from this page
http://forum.xda-developers.com/wiki/SPH-D700-Official_Roms

it wont flash, everytime it says failed, and now the phone wont power on normally, only to the download mode

can anyone help?

a guy off craigslist hired me to flash his phone back to stock, and im gonna come off looking like a jackass if all i've done is brick his phone for him

thanks!
