Using my Linux Ubuntu PC, I could root my Onyx Boox Tab Ultra C Pro as expected. But yes, after latest firmware update, the fastboot didn't work anymore.
This were the steps I did:
- first read boot_a and boot_b, using latest edl from his github repo:
./edl r boot_a boot_a_original_ufs_lun_4.img
./edl r boot_b boot_b_original_ufs_lun_4.img

- after I applied magisk to that both files and finally write them back using edl:
./edl w boot_a boot_a_magisk_patched.img
./edl w boot_b boot_b_magisk_patched.img

And for the linux guys here, I were able to install latest Linux Ubuntu 24.04 (xubuntu version) on my Onyx Boox Tab Ultra C Pro!!
That was possible using Termux, and now I can run things like VS Code to read some code and build it :-)
Thanks to being able to root the Onyx Boox Tab Ultra C Pro, I were able to install the Linux Ubuntu 24.04 using chroot, that gives the best performance possible!!

So I used Android when I have there apps that I prefer, and then I also use Linux Ubuntu, just like the same I use on my laptop - Like I prefer to use PC Firefox version instead of Android Firefox, like I can switch faster between sites/tabs on PC Firefox version and not on Android version.
And by the way, the touch inside Linux works great!! So, this is a great Eink Linux tablet!!
I am using this
cheap Bluetooth keyboard I bought on Aliexpress and that works great both on Android and Linux, as the Fx keys works like to change audio volume, change the brightness, go to home, etc.
