hello!

currently the only method for pakistan c123 is removing CPU, reball it and solder back with ball on leg N1 missing

Sir can u clarify,that if just remove cpu and place it again,
and problem will be solved or have to make jumper from n1 to pcb.
if u give the image of cpu .
it will be very easy and more usefull.

hello!

1. Desolder MCU
2. Reball it
3. Remove 1 ball from position N1 (marked on picture with red dot)
4. solder MCU back
5. Flash phone with older version with option "software restore cutted track"
6. unlock phone

option 4 will release you from restoring ball back.
phpone in future will work without this ball N1.

if anything is still not clear- please ask more

thanx sir,
but picture is not attached.
according to my knowledge mcu is a name of part of a flash file.
if I m wrong,rectify my words.
and where to get older version,
u mean save already installed file as a back up,
and after hardware again flash with same file

Hello,

According to your knowledges (that mcu is a part of flash file) I recommend you don't try to make this procedue.

Anyway, if you still want to try, you can find pictures of MCU chip and other information here:
C:\Program Files\InfinityBox\Documentation\test_point\Moto
MCU name id "D75..."
PCB photo picture with desoldered CPU:
