I tried using this guide (well-written, BTW) to root my Tab Mini C. I'm using a Windows 11 ARM VM on my Mac. When I run Zadig to install the driver, after a minute Zadig stops and tells me that there was an error and the driver was not installed. No more info than that. The CPU for the Mini C is also a Bengal, so I assumed that it would use the same driver. Maybe not? Any ideas? I can run the edl Python stuff on my Mac, but the Windows method seemed easier.... : )

Mmm, it seems like VMs sometimes have trouble with USB.
For a Mac I'd probably use the Python version.

I should port my stuff. Android? RPi? Ubuntu?

Agreed!

I pulled out my notes on how I rooted the Note Air 2 a while back, and followed that on my Mac. It all went flawlessly! My Tab Mini C is now rooted!

Also under Linux I could root my TabUltraC version 2023-11-22_07-29_3.5_9 46657f755 with the help of this guide.
The only difference is that I used https://github.com/bkerler/edl. The difficulty is that I needed to install the modules mentioned in requirements.txt by hand adding python- for each of them (for example: pacman -S python-capstone or apt install python-capstone).
(python3 setup.py build gave an error message, but that didn't matter.)
I could now read the boot_a image with:
./edl r boot_a boota.img
The rest is the same as in the above description.

Tab Ultra C Pro Rooted successfully, but the device can not be upgraded via OTA any more, sad :P

Oh... It's caused by BOOX who published a rom which is not working, it works not and rooted again successfully.

If there is a problem updating then a custom recovery could probably do that.
Since I disabled most of the Onyx stuff I do that with my Poke3 & Poke5.

Now there is a new 1.7 GB update (2024-09-11_12 etc) that does work. I can also get boot_a and boot_b with edl, but fastboot doesn’t work.
fastboot boot boota_patched.img gives the following output and hangs:
Sending 'boot.img' (98304 KB)
After Ctrl-C fastboot devices doesn’t give output anymore. I have to reboot by pressing the button and use adb bootloader again. I repeated this 8 times without success.
adb end edl work without problems, so it isn’t a cable or USB-port problem.

If your regular system is working you can just park the update.upx (still encrypted) on sdcard and:

Code:

adb shell am start -a onyx.settings.action.firmware

Fastboot has been whittled away. If it doesn't work, please quote verbatim the response.

I did:
Sending 'boot.img' (98304 KB)

And thereafter it hangs and fastboot devices doesn't give any output anymore.

What use is adb shell am start -a onyx.settings.action.firmware ? It just says that the device is already updated.

Renate · 10-12-2024, 04:43 PM

???
If you're already up to that version you don't need to update.
Modifying anything breaks the straight route to updating.
There are hashes before and after for incremental updates.
Full updates usually don't check what is there before, but may have anti rollback.

I don't know what your state is so you'll have to be explicit.

jkaltes · 10-12-2024, 04:45 PM

I said that the update did work and that my problem was, that I couldn't boot or flash with fastboot.

I had root and the previous update didn't work as others also remarked. Now the update does work, but I can't get back root.

Renate · 10-12-2024, 05:07 PM

Fastboot is out, you have to flash your Magisk'ed boot image with EDL or a rooted recovery and dd.
