I'll try to explain this as easily as possible... get ready..
Ok. My k750i won't even power on after a failed reflash attempt. While updating using SEUS,the connection from phone to USB was lost. That's when the phone was first 'bricked'.
Then I used Far Manager and flashed:
K750_R1CA021_MAIN_EU_1_CL_RED36
along with:
K750_R1CA021_FS_EUROPE_2_RED36.
The phone then would turn on but would pause at the "network configuration" error. I then read that I needed to 'finalize' the phone using Far Manager but didn't know how to do that.
So then.. (since I couldn't figure out how to finalize phone w/ FAR), I figured I'd try a new firmware flash using GFlash.
In this program, I went to the repair tab and inserted: K750_EROM_CID36_RED.mbn. Upon holding 'c' and inserting usb, GFlash detected the phone and gave me some basic info (IMEI number, CID36, etc.) but woudln't flash the erom. I disconnected, removed and re-installed the battery and NOTHING! Now the phone won't even be recognized by the pc using usb nor will it power on.
To sum it up, my phone is bricked and I need to do a fresh firmware update. Any help is aprreciated. Thnx. (i'm gonna copy /paste this to a couple other site as well to gather as much info as possible)
