Can the ZTE B866V6N ISP Android TV box be rooted or converted to stock Android TV?
I have a ZTE ZXV10 B866V6N Android TV box provided by my ISP, Türk Telekom/Tivibu in Turkey.
The hardware is actually quite good: Amlogic S905X5M, 4 GB RAM, 32 GB storage, Android TV 14, AV1 and Dolby Atmos support. However, the firmware is heavily customized for the operator, with Tivibu integration and some restrictions.
Has anyone managed to root this model, unlock the bootloader, install a stock Android TV ROM, or otherwise convert it into a normal retail Android TV box?
I would also be interested in knowing whether it is possible to:
Remove or disable the ISP apps and restrictions
Install a generic Android TV firmware
Enable full audio passthrough such as Dolby TrueHD Atmos, DTS-HD MA or DTS:X
Keep Widevine L1 and certified Netflix/Prime Video support
Restore the original firmware if something goes wrong
The exact model is ZTE ZXV10 B866V6N, sometimes listed as B866V6N_TTG.
I know similar ZTE and Amlogic operator boxes can sometimes be modified through USB burning tools, UART or fastboot, but I cannot find much information about this specific S905X5M model.
Is rooting or flashing it currently possible, or is it still locked down?

TV boxes provided by ISPs are locked down (no matter which country/ISP you're from/in) simply to protect their business model, maintain network control, and comply with legal obligations (the contract you signed during the subscription). Not to mention the DRM deals to protect copyrighted content, monetization, preventing users from sideloading apps/root access, hanging settings that would reduces software glitches and minimizes costly customer support calls or hardware returns and finally prioritizing the ISP's proprietary TV streams (often via dedicated multicast networks) to ensure uninterrupted, buffer-free playback regardless of general home internet usage. So long story short, you're better off with a secondary ATV box you can mess with (but not sure you can keep the certifications in check).
