KingboxRK-8703-7.1nv3-kodi-1225 to 6.1

[elazu1]

Hello

Does some has the version of this ROM in 6.1?

https://chinagadgetsreviews.com/download-android-nougat-7-1-stock-firmware-for-leelbox-k2-tv-box.html

Or any 6.1 ROM for that device? Or is there any tutorial to use the wifi divers from that rom to any other? I think i found a 6.1 ROM but wifi didnt work at all.

Thanks in advance.
