Solution Wifi and Bluetooth for Allwinner TX6-H with RTL8822CS module
Thanks member tbfa for providing his TWRP backup for his TX6-H here: https://drive.google.com/file/d/1jrG...ew?usp=sharing
The first solution was to copy 3 files (rtl8822cs_config) (rtl8822cs_fw) and (88x2cs.ko) from tbfa's backup, in TX6-H in counterpart folders but only for ***8822bs** firmwares. Both wifi and bluetooth worked fine if 88x2cs.ko was copied in vendor/modules/ and also a second copy of same 88x2cs.ko file was renamed to 88x2bs.ko by replacing original 88x2bs.ko. Bluetooth just needed the two (rtl8822cs_config) (rtl8822cs_fw) files in /vendor/etc/firmware/
The latest **8822bs** firmware found in the web was Tanix_H6_4Gddr_8822bs_20190323.img
The same above procedure for the even newer **8822-9** firmware TX6_H6_8822-9_4Gddr_20190722.img did nor work. Wifi was not enabled at all and Bluetooth did not exist at all.
The solution found is this:
1. Install original firmware e.g. TX6_H6_8822-9_4Gddr_20190722.img
2. Install root Explorer
3. Copy from tbfa TWRP backup in a USB flash drive, (rtl8822cs_config) (rtl8822cs_fw) from vendor/etc/firmware, (88x2cs.ko) from vendor/modules and ([email protected]) ([email protected]) (wireless_hwinfo) (wpa_supplicant) from vendor/bin/hw
4. Insert your USB flash in a TX6 USB port
5. Run Root Explorer and open a new tab with your USB flash
6. Copy 3 first files in counterpart folders of your TX6(vendor/etc/firmware and vendor/modules)
7. In TX6 /vendor/bin/etc Rename or delete ([email protected]), ([email protected]), (wireless_hwinfo) and (wpa_supplicant)
8. Copy those same 4 files from your USB flash to TX6 vendor/bin/hw/
9. Now the trick is to "Change SE context" for those 4 files. In RootExplorer select each one file, then goto up right of window, click 3 dots and select "Change SE context". Then select "Restore default context" and press OK. Do this for all 4 files.
10. Don't forget to set the proper permissions(attribute) for those 4 files. Must be the same with the rest files in same folder. Otherwise device will not boot.
11. Reboot your device and wifi bluetooth work perfect
