Do you really own so many devices? :O
- 4 pcs of WeTek: 1 x Play, 1 x Play 2, 2 x Core,
- 4 pcs of Mecool/Videostrong: 2 x KI Pro (GXL), 1 x KI Plus (GXBB), 1 x KII Pro (GXBB),
- 2 pcs of OTT M8S+: 1 x w/AP6330, 1 x w/BCM4335B0,
- 2 pcs of MXQ (1 x HD18Q and 1 x m201d).
- 1 pc of Odroid C1+.
*Although my Play 2 is half-dead and my KI Plus is unfortunately completely dead at the moment.
I assume that the first one is the correct dtb.
If the wifi doesn't work, you need the second one. It differs only in that.
