[Request] Tab MiniC Firmware Download

[alonerbg]

Can anyone help me to install the Boox Tab MiniC firmware on my Tabi 8C (minC but for china market). I live outside of China and I cannot connect wifi normally with this device. I tried so many settings, update to latest firmware, change settings for my router, my tab, but nothing worked, I'm desperate now This is my last hope

Firmware download URLs can be requested using the API: http://data.onyx-international.cn/api/firmware/update?where={%22buildNumber%22:0,%22buildType%22: %22user%22,%22deviceMAC%22:%22%22,%22lang%22:%22en _US%22,%22model%22:%22TabMiniC%22,%22submodel%22:% 22%22,%22fingerprint%22:%22%22}

Here's the current link for the Tab Mini C (stable version from 2024): http://firmware-us.boox.com/38d6130a...aa6/update.upx

Use https://github.com/Hagb/decryptBooxUpdateUpx (requires python) to decrypt the upx:

python DeBooxUpx.py TabMiniC update.upx

Then, boot into the recovery, select Apply update using ADB, connect your phone to the PC and run:

adb sideload update.zip

Worked for me after I had to recover from a boot loop.


About the WIFI issue: maybe the WIFI country code is still set to China, and it tries to use the different WIFI frequencies that your router doesn't support?

You can force Android to use a WIFI channel list of a specific country using ADB. However, this requires a rooted device.

These commands work for me on a Go Color 7:

# Log in from your PC and use root
adb shell
su

# To read the current setting:
cmd wifi get-country-code

# To force a custom country code (root required):
cmd wifi force-country-code enabled <2-Letter Country code>

# Then restart the WIFI subsystem
cmd wifi trigger-recovery

It looks like the setting doesn't persist after a reboot. But other people just installed a script that runs it on boot: https://xdaforums.com/t/guide-root-c...id-10.4703941/

Thank you, I was able to sideload the tab miniC fw to my tab8c but still the same wifi problem, and I've tried to find a guide to root Tab MiniC but have not found anything. Any solution for un-root device?

Then, boot into the recovery, select Apply update using ADB, connect your phone to the PC and run:

adb sideload update.zip

thank you, I sideloaded my tab8c with tab miniC firmware, but still the same wifi problem, and I've found no guide to root my device, any suggestion?

The problem may be because the kernel and the WiFi kernel module don't agree?

Rooting is the same as all Onyx. Get the boot image directly off the device or from an update. Magisk it. Write it to the boot partition using EDL (since fastboot is mostly useless nowadays).
