Here is what I did...and it worked (thanks B) I booted into recovery, wiped data and cache, loaded SS 4.7 (untouched) and let it boot up, went right back into recovery and flashed blackmarket.zip and rebooted...it worked beautifully, untill I NinjaMorphed a few.png's, (the launcher and bag icons to be specific) then I got the F/C again, so I restored my backup
So it does work and here is my plan for the weekend, since I have made so many changes to the SS framework-res and the system/app.apk's already (mostly.png's)...I bring my theme with me everywhere I go
I am going to take the original SS update.zip and remove the framework-res.apk and put in my themed SS framework-res then do the same with the system/app folder in the SS update.zip, and leave the original Vending.apk untouched, wipe data/cache and install my modified SS, then on my computer change the .png's within the blackmarket (using 7zip) and then flash it as an update.zip
In my mind this is foolproof, I will post back with the results
