New Nook Glowlight 4?

[jvscholz]

Ok, good news. Using "fastboot flash boot nnglow21.img"and "fastboot reboot" I was able to get it into recovery successfully. This time "update-binary 2 1 /data/media/0/update.zip" worked and the device rebooted as expected. I didn't have to create recovery in /cache as it already existed. Upon setting up the device it immediately started updating to 8.1.4.45 and now it appears as if the device is back to oem as it's no longer rooted (assuming it was rooted in the first place, I couldn't check in time). Should I reattempt to root the device? I had assumed that the latest update was already installed and that it would be safe to connect to wifi. thank you

Oh, good.
Wasn't the update.zip that you used already the 45 version that I posted the link?
Why would it update after booting normal system?

In any case, you've seen that they make it almost impossible to get to "recovery".
The stock "recovery" is only "flash factory".

Edit: Certanly you can Magisk.
I just used the boot.img extracted directly out of the 45 update.zip
You can Magisk convert it then either "fastboot flash" or recovery & dd or like I did, just dd it in the rooted UART console.

The default "sleep" images are in /system/media/SleepImageNook.
The files are called 1.png to 6.png
If you are using Magisk you can write a module to overlay those files.
They are obviously 1072 x 1448 PNG images.

If you don't like Magisk you can flash neoglow21.img (in my sig) to recovery.
Then you can mount system and delete 2.png to 6.png and replace 1.png

mount -t ext4 /dev/block/mmcblk0p5 /system
cp whatever.png /system/media/SleepImageNook/1.png
reboot
