Nice, it's good to see someone owning the device developing for it, I was mostly "blindly" doing stuff and then asking Skorpion to test them.
I tried to flash my tab with model number
tm-T227U .. this has now bricked my device as I assumed. The t227 would be same for t227u
Sadly I was mistaken. This hass now caused error .. plesse return the device to mobile carrier for repair..
Please help I want. To fix. My tablet so baldy guys

Remember this is in early development (alpha)
- Not Working:
- > Adb Sideloading
- > Vibration (minor issue)
- > Other Problems: Sometimes when you boot recovery touch not works and only solution is to re-flash TWRP again from Odin, this is kernel issue, we need custom kernel. I found out that in that case you can reboot with usb otg and mouse connected and twrp could start working on next reboot.
- Install Instructions
- Flash TWRP from Odin on AP Slot & Hold Volume Up + Power while flashing until TWRP appears.
- Go to Advanced > Terminal and type "multidisabler" (without quotes", then data wipe.
- Now reboot into system, after completing first setup of the device reboot into TWRP again to see if you can see the contents of your Internal Storage, you should, if yes you have successfully disabled Samsung encryption of internal storage.
