8850 strange network behaviour - GSM-Forum

wshadow · 03-13-2002, 17:43

hi

i got a 8850 where the diplexer (part Z670 i think) was broken away, so there was no network at all. i replaced it with one from a 8210 board (according to the service manuals they're exactly the same). now the phone gets network after turning on, but after about 5sec the it's gone and the phone won't ever find network again until you remove the battery. whats wrong? i tried sw update and resetted everything but nothing changed....

Hello
It seems the RSSI parameter unmatched you have to connect your phone with wintesla and testing instrument to adjust it.
