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 
 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 
 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/
