I have purchased from eBay so called unlocked Samsung Galaxy S5, Android V-6.0. AT&T probably still has its IMEI listed in database. It works fine with T-Mobile SIM card.
Phone has nine AT&T related apps and I assume some firmware installed by AT&T. I want to DISABLE or FORCE STOP or UNINSTALL all AT&T related app and SYSTEM FIRMWARE using Application Manager and/or an MS File Manager or do a Factory Reset of needed to get the same phone as sold by manufacturer (not sure if it is possible with AT&T phone).
I do Disk Image for PC to 100% restore previous Image. Is there any Android app similar to Disk Image which restores everything including system firmware? The-MobileGo backup/restores Music, Photo, Video, Message, Contact, App File. Nothing mentioned about system firmware. Thanks for help in advance.
