Well no voltage error in your case but are you using LibreELEC-WeTek_Play_2.arm-9.2.8.18.img.gz or LibreELEC-Generic_S905.arm-9.2.8.18.img.gz with gxbb_p200_2G_wetek_play_2.dtb is it same thing ?
Since it is not DVB-S, there is no LNB to be powered (13-18V DC), so there is obviously no such problem with this tuner. Regardless, there is a 5V DC output for possible antenna signal amplifiers, but for terrestrial signal reception (DVB-T/T2) a passive antenna is basically sufficient, and for cable TV (DVB-C) this is not even necessary.
For WP2, I strongly recommend using the WP2 image, because it is optimized for it (different boot method, remote control codes, kernel drivers, etc.), and between the base modules, only this one contains the wetekdvb driver.
The abdroid box os uses kernel 3.14.29 so drivers should be compatible but I have no idea how to proceed.
I extracted your stock ROM image with AMLogicTools and unfortunately the driver is not included as a module, so it is impossible to extract and use it from its original environment.
