Lenovo only released the old 4.9 kernel source for the TB-X606F from its Android 9 days, which meant their Android 10 release was basically stuck with unusable/unbootable source. So I grabbed the 4.19 Android 11 kernel from the TB-X306F and ported that over to the TB-X606F running Android 10, with a lot of help from Claude and ChatGPT lol. that whole Android 9 to Android 11 kernel then back onto Android 10 explanation sounds confusing, but both tablets use the same SoC, which made the port pretty realistic. It’s a pretty big jump from 4.9 to 4.19 and most things are working fine so far. Still fixing/testing a few remaining bits, but Android 10 boots and is usable on 4.19 the majority of it, it only took a few hours too lmfao

Kinda crazy what you can achieve with LLMs nowadays. I used Claude Opus 5.5 on the $20/month Pro subscription for this. I tried my best to avoid an ugly patch series on top of mainline Linux and keep the pmaports clean. They won’t let me make a PR anyway, but hey, lmfao it’s working, unlike what the wiki says. WiFi Bluetooth, Audio etc will prolly work in a day or two too
