I am using mac. I am trying to install twrp on my Galaxy Note 8.0 GT-Nn5120, via adb. ADB can detect the device when in normal mode but when i boot into recovery mode, it can't detect the device.. What do I do
You can't ADB in recovery mode, not with a stock recovery. You can only ADB Sideload which is used to flash zip packages (updates, gapps, etc). To install TWRP, you need to flash it in Download mode.
- Download TRWP or here
- Boot in Download mode (Hold volume down then briefly press the power button. Press Volume up to confirm).
- Download and unzip Odin then launch it.
- Click on PDA or AP button and select TWRP file you downloaded previously (Should be in .tar format. If in zip, unzip it)
- Click on Start button
- When you see PASS, disconnect the phone and power on (Hold volume up this time: you should boot in TWRP recovery )
