Hi! I have a P1 from Canada but I live in Hungary. My P1 sometimes lose network and require the PIN. I upgraded the ROM to B534 (before it I had u9200-1v100r001canc113b104) but the baseband version was not upgraded. Baseband version: IMC1202_20120510_PENTA. There is a horrible problem especially when the battery low. When the battery level is low (40%) require the PIN several times sequentially. Please give an advice which will solve my problem. Thanks a lot.
