I would be looking into patching Settings.apk application on edge.senior so that it would not disable power saving preferences on that device
for framework.jar I used baksmali/smali.
To modify an apk look for a tool called apktool. it intelligently unpacks apk files and then uses baksmali/smali to decompile it.
So get all of those.
the only problem is that it can't decompile jars and dexes into java code, it decompiles into a weird mishmash of java and assembly called smali for lack of a better term. It's not very well documented, but just googling smali to find the tools will get you some examples.
