02x 1b Dead How To Flash
 

I have this phone dead brought to me like that no traces of water or liquid want try to flash but don’t know how to and which flash files to use and pinouts (and wich color)of the cable.i have already checked documentation but didn’t find any pinout or way to flash for this phone .

You must check documentation once again, because I can't understand what kind of documentation was checked if nothing was found.
use "Cable Selector" and see cable/pinout information
see here to get test-point picture: D:\Program Files\InfinityBox\Documentation\test_point\BenQ-Siemens

i found the pinouts but didnt find one for O2x1b.and how to flash,wich files to use?

hello!

02x1b pinout, same as others, can be easy found in our shell.exe pinout finder.
files for flashing on our support site:
root/ flashfiles / BenQ / O2X1b /

ok lastly please can you tell wich color is GND,TX and RX in rj45 cable.thanks

hello!

different cables have different colurs.
you better count needed pins on connector side and look what colur they are
