1- I'v rooted my GT-N7100 long time ago (couldn't remember the method but the developer said the methood doesn't make any alteration to your device, Just root privilege. even doesn't install CWM)
2- I'v installed CWM through "ROM Manager" android app last week.
3- Installed some 4.4.2 ROMs but all unstable, crashing in few minutes. (All the ROMs got good comment 'n I think there is a problem with my device!!)
- DN3 (Ditto Note 3) ROM
- CM11 ROM for Galaxy Note 2
- BLUE LIGHTNING
4- Decided to flash official 4.3 firmware downloaded from: "http://www.sammobile.com/firmwares/3/?download=12202" through ODIN, but got "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again“ message.
5- Decided to unbrick with ODIN, but every-time it fails (tried different ODIN versions 'n different USB ports)
6- Tried to do so with KIES, but it does not recognize the device (Stucks on connecting message, troubleshooting doesn't effect). Also tried "Tools> Firmware Upgrade and Initialization" option directly, It crashes in EVERY STEPS.
So if u have any Idea to fix this, please share!
