on Christmas i woke up to a notification that says update device information on my home screen there is a transparent popup that only goes away when i open an app. i found a forum that suggested to disable the factory mode & factory test apps and that has made the notifications go away but my lock screen and the ability to restart power or go into airplane mode. i want my lock screen back. in all the research i have done everything is pointing to a corrupted partition the EFS partition. which i have a backup of however it does not work and its tiny tiny (not sure if it should be) on dec 24th i restored my phone using titanium backup pro everything&still is was force closing on me and i keep getting messages from superuser saying its granting access to shell.. i tried restoring a different backup i even tried to flash the stock rom from this thread but now odin isnt working when i puch start windows pops up a window saying odin has to close to unknown issue. it worked fine in November im so confused this is my first root and i have done great so far but im stumped your time,patience,kindness&experience would be much appreciated. the trasnparent popup says PDA: M840VPAMH5 PHONE: M840VPAMH5 CSC: M8400SPTAMH5 HARD WEAR: M840.06 RF CAL DATE: NONE SMD: O1N, PBA: 04N, CAL: 07N, FINAL: 11N UN: C043008738CFD90 FRONT CAM: SILICON SR13OPC20 REAR CAM: SONY ISX012 NA TSK NA NA TSP: CY03010e CY03010e CH: 0 UART: DM,USB,NULL.
