I have been using Market Unlocker for so long, suddenly it's no longer working. I have tried different versions, clearing play store/market unlocker cache, forcing stop, rebooting... everything, but nothing works. I'm on Stock and rooted; I tried on 4.2.1 and now on 4.2.2. I have Titanium Backup Pro, in case there is a workaround using it. Thanks!
