view story

http://androidforums.com – My phone was working fine with Cyanogenmod Rom for a quite a while now. But I put someone else's memory card (after unmounting my sd card) and it started restarting. I tried to start the phone with my memory card, and even without any memory card at all, but the problem still persists. Here are the details of my phone: 1. ClockWorkMod Recovery 2. CyanogenMOD 7.2 rc5.7 3. 8 GB memory card partitioned, with sd-ext partion of size 1GB, for using DarkTreamor A2sd script I did suspect that there could be a little problem if I tried to open my phone with my friend's memory card (size 8 GB (General)
