[EVO 4G Q&A, Help & Troubleshooting] richp1970:
I did some reading before I posed this. I am in the process of testing roms and I did a backup of my original sprint rom and kings rom nightly. I used the backup before for kings, restored and it worked. I read that it can be the battery to low or not enough space on my sd card but thats not my case. I copied and pasted below of what the log said..
