Okay... sorry about the delay guys. My SECOND Biostar motherboard fried last night. (stay away from their AM3 socket MBs if you build your own too)
Update on my testing so far;
Since I had all my ROMs stored on the computer that fried last night (SATA drives), I had to pull out the old backup machine (IDE drives) to get back on line until my new machine gets another MB... anywho,
I tested this mod on Metropolis 1.1.0 and 1.2.0 - both worked fine.
Tested on LD's first version on #2 - it worked, but not on any of the later versions.
Oddly enough, even on Metropolis 1.2.0, after a while the SecMms.apk would just disappear. (???) I suspected my phone, because it's been loosing root sometimes after rebooting - SuperSU looses it's Binary, and can't update (and it's happening randomly - no rhyme or reason)... I seem to be plagued with bugs in just about every electronic device I own. lol
Maybe it's time to save all the data on it, completely wipe everything and start over fresh. Apparently, just wiping System, Factory Reset, Cache and Dalvik between ROMs aren't enough. lol
BTW - has anyone noticed any issues with TWRP 18.104.22.168 in regards to dirty/incomplete wipes?
I'm going to play around with it for a bit longer and get back to you guys.
