I don't why Moto banned 5Ghz wifi on G8 family. This is really a stupid decision. But our wifi chip is wcn3390, I'm 100% sure our hardware supports 5Ghz.
Here I provide a method to unlock it on custom ROMs. Because I'm not sure if vendor_overlay could work on Official firmware.


You only need to flash Magisk module, it works on both stock and custom ROMs now.

Step 1 Mount product partition
flash twrp and boot into it. Mount product partition in Mount menu.
Then connect to your PC, run this adb command to make product partition writable.
Code: 
adb shell mount -o remount,rw /product
Step 2 Create floder
Run these adb commonds:
Code: 
adb shell mkdir /product/vendor_overlay/29/etc/wifi
adb shell chmod -R 755 /product/vendor_overlay/29/etc/wifi
Step 3 Push custom wlan config
Download the WCNSS_qcom_cfg.zip provided by me, unzip it, then copy WCNSS_qcom_cfg.ini to the adb tool root floder.
Run these adb commonds:
Code: 
adb push WCNSS_qcom_cfg.ini /product/vendor_overlay/29/etc/wifi/
adb shell chmod -R 644 /product/vendor_overlay/29/etc/wifi/WCNSS_qcom_cfg.ini

Reboot, I think you already unlocked the 5Ghz wifi bands, you could enjoy 433Mbps speed now.


Also provide a kernel which built-in upsteam qcom wifi kernel drivers. But this is not necessary. You could replace it with anykernel or AIK.

My stock rom for Moto G8/G Fast had this built into it, I had access to 5G access point out of the box, the custom roms I use all have it as well, so...

This is interesting, according to @Beetle84 only G fast supports 5Ghz, can you check the wifi chip with device hw info?

From Googling the difference it looks like the G fast comes with 5Ghz out of the box.
Seems to be the same supported WiFi chip though.

Can you dump your partitions and uploaded them?

Some of your requested partitions couldn't be dumped:

Doesn't matter, can you upload the rest img you dumped?

Thanks for this info! This is very interesting, Mine is G Fast, but the vendor I used is G8's. 5Ghz works for me.

Thanks, I will try to restore your dumps on my G fast.
------------------EDIT----------------------
emmmm, I am so sorry, you dumped
Code: 
mmcblk0
, this is the whole image of your EMMC.
My bad, it is too large, 44GB....
Can you delete it and repack the dumps again? The normal size of useful partitions should be under 500MB I think.

Code: 
adb shell mkdir /tmp/dump/
adb shell dd if=/dev/block/by-name/apdp of=/tmp/dump/apdp.img
adb shell dd if=/dev/block/by-name/cid of=/tmp/dump/cid.img

Okk, I tried, I still have 5Ghz after restoring your imgs.
IMEI didn't change, some info must stored in other places. let me upload mine.
You can try:
