Finally I found out the problem today. Voltage was lowered while OFT flashing the file into the ECU. First time flashing shows completed but actually not. Then I tried to start my car, car won't start because file was incomplete and voltage was too low. The voltage was too low when I tried second and third times to flashing the ECU, so OFT shows error. Today I tried to charging the battery and then car started. I flashed stg2 uel 93oct into the ECU and it worked.

Big thanks to @FRSBRZGT86FAN and @steve99 helped me finding the problem out.

Use the oft to write bact the Original File to the ecu the one in the top slot.

if it still wont write try this

Switch off ignition
Remove positive battery terminal
With battery disconnected, depress brake pedal to bleed off and redidual power
Replace battery terminal
Flash your original tune to car on first turn on of ignition

Ie plug in oft turn ignition on go to write , wtite original tune without turning ignition off even if oft asks you to.

After that i think you got big problem, contact the oft guys.
