Hi, I am using several UDOO Neos with the latest Android image v6.0.1 beta2, and want to boot into TWRP recovery mode, however it does not seem to function. It always just boots back into normal android. I have tried via - Android Settings > General > Reboot in TWRP Recovery - adb reboot recovery on a connected PC - reboot recovery in a su terminal in Android (I am trying to install GApps) Thanks!
OK I am answering my own question, should have tried this first but maybe it helps someone else: Looks like TWRP recovery will only work on an external power supply, not if the board is powered via USB. Might add that to the wiki? https://www.udoo.org/docs-neo/Cookbook_Android/UDOO_Android_Settings.html
