3410 keeps on turning off (no network)

[skynet]

hi

i've looked around for the same problem, but found that mine is different.

the whole story goes like this:
i've modified my 3410 software somewhere in the past, killed MCU and FAID check with genolite 2.0, (the last bytes of the MCU+PPM was DE AD DE AD FA 1D) and it worked fine with my fone.

then i added security code to a menu (reminders), flashed the stuff again to the fone and it worked (no network losing) till i tried to enter to the security-code-protected reminders menu, then the phone restarted and never found network again (it starts up showing the operator logo and keypad tones the the tones go away then in a minute the phone restart).

the temporary solution is that i flashed a fubu of another 3410 to mine and of course changed the IMEI back to my phone's one.

so now when i flash the original fubu (the one the phone has worked with for over a year) network losing comes back.

I used the following tools to calculate FAID:
knok phoenix build 1
knok 2k3
nokia tool 1.9 imei
eeprom tools 3.1

but no success, tried to change IMEI also and cleared SP locks again and did SFR also.

can anybody help???

thanx in advance!!
