Phone freezes/restarts.NOT software

[hyper24]

I have an 8210 and an 8250, they both freeze some time and some times they even restart. I know its not a software problems because i have flashed both phones with software that i know that works 100% that i took from my other phones that work fine. So does anyone know what the problem is and how to fix it?

If you flashed the phone, you must update FAID (Flash Authority ID). It can do by Nokia Tool by Rolis.

If phone will still work wrong, try reset EEPROM.

I know its not a software problem, i have been flashing phones for over a year now and i know all bout the faid and that stuff, But this isnt a software problem, im pretty sure of that. It gets fine reception. Has anyone had a problem like this or knows how to fix it?

It's on the right of the back, below right of the CCONT and Upper right of the CPU. Part number should be V257B if I remember correctly.
