could this also apply to ese81? i'm experiencing similar problems applying the framework-res on rooted ese81 (adb root, not pete's)
Theoretically, yes. The only real issue I've seen is with custom roms whose system partitions are too full with all their features. In those cases, you can't push the framework-res.app back because it copies the whole thing over before replacing the existing one, so worst case scenario is that you take the time to copy and paste the icons you want to only get an error message in command prompt.
I assume that there's enough room in the stock rom though.
Create a nandroid backup and give it a try. If you want to make sure it will work first, do the entire process without pasting in the icons you'd like to use. Basically, adb pull the framework-res, then push it back without changing anything to make sure there's room.
I worked a 12hr day today, but I'm available for at least a couple hours tonight if you'd like some help, but if you can push it back without making changes, you'll be able to edit the framework-res file that will be in your sdk tools folder on the PC, then replace the adb pull section of the first set of commands with everything from the adb push down (push it to the phone, then use command to reboot).
If you go for it and don't need help, let me know what you find out please!
