http://androidforums.com – I think I bricked my phone, I can get into Odin mode but when I reboot the phone says firmware upgrade encountered an issue. please select recovery mode in kies & try again. when I open kies, the device doesn't open in kies but the usb connection confirmation sound play. I've tried using the SPH-D710VMUB_FJ12_CL1135978_Stock_Restore exe to flash back the stock firmware and kernel/Recovery but every time I click to start the flask process I get "md5 hash value is invalid". im lost as to if I can fix this or if its a goner....:smokingsomb: been tryin to ease my mind (General)
