this stock thing is catching a few people out, for some reason, no matter what dashboard they are on they seem to think that by going back to the original stock then it will still work, but as you found out mate, thats not the case, there are at least 3 'stock versions' depending on what dashboard you are on. really old dash would use the standard stock, then you have a pre and post 'stock' firmwares released with the latest cfw, these are the ones you need if you have been updating your dashboard recently
