My Samsung Tab 3 is rooted by kingoroot and that worked flawlessly, I installed it using Firefox on Android.
That is, until the installation of F-secure anti virus program finished and the Tab 3 not being used for about 3 weeks.
After 3 weeks, at login into the user account things seem to go very wrong and very quick, starting with a window telling me 'program has stopped' followed by a crash and reboot. There's no way to stop/delete any app (anti virus or kingoroot) that causes the system to crash immediately and reboot again. In recovery mode I tried to wipe both user data/factory reset and cache. But nothing seem to make any changes. Next I tried to flash the appropriate Android 4.4.2 using Odin in Windows, but allthough the device is found and connected, any version fails to flash the firmware. Only version 3.07 seem to work, the flash finishes in Windows only but not on the Tab 3. I can tell because on the Tab 3, there's no statusbar that shows up during flashing. But hardware doesn't seem to be the problem, because using Heimdall does seem to flash the separate files from the extracted stock ROM. I can tell because there's a statusbar on the Tab 3 that show up during flashing. Yet I noticed differences during flashing, when flashing 'system.img' finishes, the Tab 3 immediately goes into reboot, but for all other components of that same ROM that are flashed, it took several seconds until Tab 3 reboots.
So, my guess is that at immediate reboot after flashing 'system.img' the flashed image file does not replace the installed file on the Tab 3, but is deleted instead.
That would explain as to why there's no change after flashing completes with Heimdall.
That also may explain as to why flashing with Odin in Windows fails.
Question now, is it 'kingoroot' that actively refuses any changes at flashing, or is it F-secure, or both?
How do I get rid of it?
How/where do I get an untouched full version of Android 4.1.2 JB as to Android 4.4.2 KK seem to be an update version only.
