Pre-condition you know what you are doing. You unlocked bootloader and you know how to use command line. I was not able to flash TWRP provided here. I flashed it from fastboot. 1. Download this archive https://pucina.dedyn.io:8181/data/public/f09293 2. Extract it somewhere to your PC (let's say c:\twrp, let's call it N1) 3. Connect your tab to your PC and boot into fastboot. 4. In Windows explorer, when twrp (N1) folder opened press Shift and right mouse button and select "Open command window here". 5. Run install_TWRP.bat 6. When tab re-started press volume+ and power button and hold for a 5-6 seconds. You will enter TWRP. If this will not happen - re-do this again, because you need to get in TWRP first time after flash to "fix" it. For those, who can't enter recovery with buttons combination - use this archive for installation: https://pucina.dedyn.io:8181/data/public/b3984d It should reboot into recovery after installation. Recovery is exactly the same as in item 1. So download this and do the rest in list except item 6. Should work. All credits to clever guys, not to me. For those, who already installed TWRP, TWRP is working and they have no other option to get into it: Command "fastboot oem reboot recovery" will help you. For those, who don't know how to run it, please read instruction about how to fix 963 error PART2.
