[Request] Tab MiniC Firmware Download

alonerbg · 03-04-2025, 10:59 PM

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:

Code:

python DeBooxUpx.py TabMiniC update.upx

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

Code:

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:

Code:

# 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:

Code:

adb sideload update.zip

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).

No, that is the latest unless there is a beta channel and someone is subscribed.

I’ve had similar issues with devices made for the China market. One thing that helped me was using a VPN to make sure my device can access services outside of China. Also, check if the firmware version you’re trying to install is the global version, as the China-specific one might have limitations. If you can, try a different Wi-Fi band (2.4GHz instead of 5GHz) and see if it helps with the connection

Yeah there is v4.0 on Tab Mini C but it's only incremental update from 3.5.4, not a full update file. Do you think it's safe to convert tab8c from v4.0 chinese to global 3.5.4(which is the latest)?

No. Not with an incremental.

No, i means I have global full (not incremental) firmware 3.5.4, but the tab 8c is already on chinese 4.0 already

Renate · 04-26-2025, 01:19 AM

It probably will be ok.
There could be some problems with system setting if things have changed.
For instance the format of /onyxconfig/eac_config has changed from JSON to MMKV.
(* not sure I got the filename exactly right)

If you have made a full, raw backup with EDL and you have the time, why not try?
