yup, guess re-signing screwed it up. Thanks for the tipI think I found my issue... rebooting the phone now after attempt 2I was able to swap in new battery status icons without issue. Check your permissions.
edit: nope. Stilll all FCs, damn. I'll try with root explorer or something... I hate not being able to figure it out lol
Don't try re-signing, just open the APK in winrar and replace the PNGs. Should work fine, except you may have to chmod after replacing it on the phone. I'd also do it while in recovery.
