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.

If you flashed the EROM you are out of luck. There is no point in really flashing an erom unless for special reasons (and yours wasn't one of them). Forget far manager and wotan; you need to buy a service cable and recover and reflash EROM (took me an hour on my 1st go )

if you want to finalize your phone you need to copy the certificates into FS/tpa/preset/custom

FS


tpa


preset


custom

thnx turns out that the included cable w/ k750i works fine as service cable so i'll just use that but the problem is that the phone won't power on whatsoever or connect to pc any longer thru the usb cable.

if i can somehow get it workin then i'll use the steps thru FAR manager to flash it but atm FAR won't even recognize the phone.

The service cable will recognize the phone as it has the special "black box" on it and all the fastport pins for the connector which will force the PC to recognize the phone and the phone to connect to PC so you can flash your EROM and fix the phone.
