I did this with no problem you may have hardware problem.

Did you flash phone with main and fs file with same version R1BC002 ?

[mentari]

im did flash it with correct main + fs.

my phone brand new.

just want to change language.

the phone is still alive. but had configuration error.

Just need complete phone only.

No Problems here
Just Downflashed 10 x K750i R1C021 Branded Virgin TO R1BC002 with no problems at all
Try "to Complete phone" with no other options ticked.

Dear friends flash your k750* with Davinci Client 16.4 and Finalize with FAR manager.

It exists some thing that it is necessary to know:


1 - you have to have installed the Drives USBFlash to use the cable DCU60.


Select and Download the firmware for the K750i from "Flash Files" tab in davinci. Mark Download MAIN and FS option there and click on Get files.

2 - to open Davinci 16.4, introduce the files MAIN and FS, and press "Flash." DON'T MARK THE OPTION FINALIZATION.

When finishes writing the files MAIN and FS, closing the program Davinci.

Decompress the file custom.rar(download it from www.topsony.com) and save inside the same directory of the program FarManage. And must edit your CID number and version in customize.xml file.

Open Far Manage:

1 - Execute the command (Alt + the key F1 / Alt + the key F2) - a new window will Appear, "SEFP" press.

2- Select the cable, speed, and I model of telephone, "Enter press The Matrix"

3- Press the button "C" and connect the cable to the telephone.

4- Press FS

5- Select the directory / tpa/preset/system/custom/

6- Select the directory "custom" in C:\Files Programs\Far\custom.

7- Select all the files with the right button of the mouse, click file for file (the selected files will be in yellow) or use the command Ctrl+, later press in "Copy"

8- Confirm the operation, press in "Copy"

9- Once ended the process of copy of the files, is necessary to finish the operation loading CSFS (SHUTDOWN CSFS loader).

The square of I dialogue "Shoutown" will appear when you ascend for folder root FS: for this it is necessary to go pressed in the two "points" that appear up of everything in the left field. When the message appears: "Do you wish to SHUTDOWN CSFS loader?" "Yes" press.
Now restart your phone and enjoy.
