Thank you so much for your labor,my box isV88 MINI RK3299 2Gram + 8Grom RTL8723CS WiFi Bluetooth
I tried to flash a lot of ROMs from 4PDA-BBS, only one ROM containing RTL8703BS RTL8723CSWiFi Bluetooth driver can be used, other ROMs cannot use Bluetooth WiFi because of different drivers. So I'm looking around for ROMs that can support
Can I try flashing your ROM? I'm using 2017 Android 6.0 ROM, now it's a very unfriendly ROM
