About 5G WI-FI, Can you describe it in detail?
Not sure if there are issues on wifi, I am using netgear R8000 router, it has 2 5G wifi and 1 2.4G wifi running at the same time. for VIM3 with V200103 ROM, I can find the 2.4G and one of the 5G channel for my router. One of the 5G channel cannot be found.
On the router that cannot be seen, is that router broadcasting its SSID?
Hi. How to fix wifi at 5 GHz ???
Well since the rom as root, just edit system build.prop or is vendor build.prop… well in one of the two LOL i just cant be sure now, just check both build.prop…
And just comment out ( put a # in the beginning ) ro.boot.wificountrycode=CN , save and reboot and voila 5g back.
In the sdk just go to kvim3.mk, kvim3l.mk and comment ( put a # in the beginning ) the :
PRODUCT_PROPERTY_OVERRIDES +=
ro.boot.wificountrycode=CN
And that is it!
Thank you very much for your help! I’ll try to fix it, but I don’t understand much about it yet …
Many thanks!!! …
Thank you all for your help! Made changes to system / vendor / build.prop. WIFI 5 GHz began to work !!! …

All mainstream streaming APP not work properly on this FW: Douyu,Huya,Bilibili, …
Playing with black bar at bottom and right side. (dot to dot or scan issues)
The original FW(190809) is perfect on this.
Navigation bar can be closed in this FW, good news!
Status bar hiding still not available. o(╥﹏╥)o
