State

TWRP builds and is fully functional (hopefully).

Test without installation

Not possible, fastboot boot <path_to_recovery_image> is not working on this device :(

Installation

1) enter fastboot; 2) in cmd do fastboot flash recovery <path_to_recovery_image>

How to build TWRP

1. repo init --depth=1 -u git://github.com/minimal-manifest-twrp/platform_manifest_twrp_omni.git -b twrp-8.1
2. repo sync -n -j 1 && repo sync -l -j 4
3. clone this repo to <twrp_repo>/device/nook
4. apply patches from <twrp_repo>/device/nook/patches directory
5. open terminal in <twrp_repo> directory;
6. export LC_ALL=C
7. . build/envsetup.sh
8. lunch omni_gentoo-userdebug
9. mka recoveryimage

if everything is successful you should find built recovery by path /out/target/product/gentoo/recovery.img
