This is how to disable signature checks using seo's code that has been around forever, now for the EVO LTE on ICS.
Gonna loosely quote SteelH's [How To] post opener:
This reference guide is to tell you what to edit to disable Signature Checks for the EVO 4G LTE in Services.jar. It is not an all-inclusive how-to on adb, decompiling/recompiling apks, etc. There are already several very good sources right here on XDA for that information.
Decompile Services.jar and look for \com\android\server\pm\PackageManagerService.smali
Do a whole-sale .method change and replace the entire .method with this one:
p.s. you will notice that there is no .line numbers and the .registers are now .locals, that is because I use a different baksmali cmd than what is the norm. I use:
notice the extra -l -b
the -l(thats a lower case L not and upper case i) changes the .registers to .locals and the -b removes the smali debugging stuff that is not needed. Most custom rom builders know about this edits but this is for the average user that would like to make edits on their own and want to make edits to system/apps.
