dunno, I never owned any tablets (with an exception of Chromebook Duet - Kukui/KRANE). This is an MT8188 version (Geralt/Ciri) that @9lore bought for university and handed to me to fix touchscreen and trackpad (I2C over EC, hammer).
There are folks hacking on iDevices though: https://wiki.postmarketos.org/wiki/Apple_Generic_iDevice_(apple-idevice)#Booting
