Basically yes. He just pulled Vending.apk out of an official signed 2.2.7 update and combined it with your mod.
It will flash and load fine but as soon as I download 1 app, it FCs on install, and then is in a constant FC. Tried clearing data+cache on Market, no-go..
Stock. Just have a couple of my own mods. Nothing to do with the Market though.
ThuggishSouljah's version works if I flash it over a silently updated stock Market. Yours works if I nandroid back (my backed-up version is 1.82, couldn't find a way to install the 2.12 apk to try that).
here try this market. this is going to place it in system\app labeled vending
if you have a market anywhere else delete it
