I also have same problem....
Some of new 3310 v5.13 (made by nokia original PPM G) can only working with 1-2 operators while the other got no signal, some of them got full signal, 3-4 sec then drop....
Result when manual network selection is.. some of them can show all network that aviable, but "no access" when try to register...
We already try to flash it with rolis, up to v5.13, also try use virgin eeprom, also try with full flash from healty phone, calculate with eeprom tools --> result the same...
Also already try to flash with DDP and nokia wintelsa files, result the same....
Some of them we try to change the PA but still same....
any more idea?
