I have a tanix tx6 4/32 . Purchased from Vontar store , china. I found 3 problems
1. Bluetooth not working
2. Max resolution in display settings is 1080
3. It has Alice ux lite version.
When i tried to update with latest firmware downloaded as .img from official site , it simply fails.
Then I opened the box and found that its board it CS_H6_tx28 v2.3 printed.
A sticker is there labeled as TX-6 A (819) .
I also noticed a a change in IC .
When I searched for tx6 board online it has RTL 8822 radio IC .
My board has a XR819 IC .
Now what is difference between these two???
Is it why bluetooth does not work?
The update file on official site says its for 8822. Where will i get update for xr819 type model?
Pics are attached.
