The codename for the Wi-Fi version is B8000-F, and the 3G version is B8000-H. A similar device is the Lenovo YOGA Tablet 8 (B6000-F, B6000-H). The kernel source code for b8000 and b6000 is the same except for a few lines.
Probably the B8000 and B6000 can be implemented in a single package.
ro.product.board
contains the same prefix (codename?) blade
.
Therefore, if the postmarketOS port of the B8000 can work on the B6000, the codename may be changed to lenovo-blade
.
B8000-F : blade10_row_wifi
, B6000-H : blade8_row_3gdata
,
A3000-H : a3000_row_call
, B8080-H : MSM8226
SoC
MT8125/MT8389 is almost the same as the MT6589. The Wi-Fi version is equipped with the MT8125, while the 3G version is equipped with the MT8389. The kernel source code for MT8125/MT8389 is the same as that of MT6589.

How to enter flash mode
Fastboot
Installation
Using pmbootstrap
Work in progress.
Kernel
The official source code ( JellyBean KitKat Raw archive ) is so dirty, broken, and didn't boot after building, so the mainline is the target. You can find out about porting status here.
U-Boot
Boots. But the port is incomplete. You can check the progress of the port here.
Development is stopped until the kernel exceeds the size of the boot partition.
