99% malfunction is broken balls under CPU, so rehot or reball

zepi: can you give me pictures of schematics and show me? I need a service manual and pictures of where I need to solder the loose points?

Try to rehoot CPU and it's ok.

If you see on display sarching network try to reball RF singnal processor if proble not solved change RF, if you see No network change RF and Power IC.

Hi

Zepi is correct

For no network on T600 i would reflow the Digital Baseband ASIC (LMX3405) and re-solder (max 240 ºC).
