I have used my S7 since 2017. Then I got another phone. After three months of being in a box, I tried to power up the S7 Edge. I got surprised as it now is stuck on Samsung logo screen.
Phone was charged and was working before I put it in a box. When I took it out, it would not respond at all, battery was dried totally. Even being charged 100% does not fix the issue. These are the steps I tried: 1. Wipe cache partition 2. Master reset 3. Safe mode 4. Reboot to bootloader
All of them do not work, phone is always stuck with Samsung splash screen. When I enter the Volume DOWN, Home and Power key menu, I see the message: Installing System Update (stays for several seconds), then it shows error. After that I enter Android recovery.
Phone responds to charging normally. It has that animation showing power percentage when its turned off.
Any advice as what program and what I need to do to restore the phone so it can boot is more then welcome :).
