E2550 flash and then unlock ok (trick inside :D )

[cycofcgb]

Hi,

trying to read codes, I killed the phone, no more turning on.
I could not flash it either, always failed to connect after sending loader.

Maybe it has been said before, but use 5+8 to connect phone, and DON'T release them until second connection.

I used E2550XXKD1_OXAJI1 firmware from support, which has these languages : DEUTSCH/ENGLISH/ITALIANO/FRENCH/ESPANOL/NEDERLANDS/PORTUGUES/TURKCE/POLISH/IRISH

here's log of flashing and unlocking :
