I bought a used 2g phone in working order, activated, locked and otherwise in good condition. WIFI worked was at 3.12 Os already. Ran blackra1n,bootnueter and popped in a TMobile SIM and all worked fine, for a while. In the next few days I started to get searching for signal, followed by No Service. A reboot of the phone would bring everything back, next the WIFI quit working. I have restored the phone, ran all the programs again with the same result. I ran Irecovery with the "Radio readnvram" and got no responce. I read that was a sure sign of a hardware problem. My final try for a software fix was to downgrade to OS 1.14 and to run Iliberty with the WIFI fix. No luck still no WIFI. My question is would a new comm board fix my problems?
