I just got a custom recovery image installed on my Optimus V, and I am trying to do a complete backup before I proceed to trying out new ROMs. I did a nandroid backup, and that worked fine. When I did "Backup Google proprietary system files", it did not present any errors on the device, but it also didn't seem to copy anything. (It only took a few seconds, and I couldn't find anything on the SD card.) So I checked the recovery log, and found an error I have attached the complete log, but here is what I think the relevant pieces are: Code (Text): Backup Google proprietary system files? Press Menu to confirm, any other key to abort. Performing backup : .mount: mounting /dev/block/mtdblock1 on /cache failed: Device or resource busy .Skipping odexed apk /system/app/NetworkLocation.apk . Backup complete! Any ideas on how to correct this? I haven't been able to find anything similar in my searches (is my Google-fu weak?). Could the problem be caused by the fact that I'm running a recovery.img that is for the Sprint version instead of VM?
