The problem is this: I've deleted download provider for error in titanium backup... So when I tried to download something from the store the download progress continued to flashing but it doesn't download anything. So a friend of mine which had bought the same phone, made a backup on titanium of download provider on titanium and passed it to me, in order to allow me to re-install on the smartphone.
I've re-installed the app but as soon as I try to download anything I get error 419 on play store.
I see all the guide on xda to solve the 419 error, and nothing seems to work: I've tried to delete the google account, I've tried to wipe cache and dalvik from the recovery, I tried also to flash the unofficial cm11 to see if the problems continues, but nothing, otherwise it start do bootloop, so I've come back to the nandroid I've done on cwm.
Does Anyone has a solution for my problem ? I repeat the problem is error 491 on play store, and I think that the problem is that I've unfortunately uninstall download provvider from titanium (now I've installed a titanium backup of download provider from a friend of mine who own the same moto g)
PLEASE SOMEONE HELP ME...
