Aaaaaaaand we have… mainline!! With downstream DTB and simplefb_earlycon, but now I can get to fiddling with DT knowing there are no other obstacles \o/ #mainlining #mt8183 #postmarketOS

PROTIP: when trying to get an Android device to boot something new, first just try to repack an existing boot image, erase the boot partition and flash the repacked image.
The first problem was that this tablet's LK absolutely needs a signature (`avbtool add_hash_footer` with any random key is […]

Back to the mt8183 tablet: probed all those test pads on the back of the board and indeed none seem to be UART TX.
On the other hand, decompiling LK reveals what exactly it expects from the device tree…

Board. Sadly no labeled UART points. Bunch of unlabeled test pads on the back, mooostly corresponding to connectors. But maybe I could find TX by touching all of them..?

It actually has a SECRET FOURTH BUTTON 0.o
That seems to hard reset it and boot into some extra factory mode that exposes something over USB HID

Did not manage to get it to boot "blindly", knowledge of the cursedness of android firmware for related SoCs did not help. Had to open it after all to look for UART pins.
This was HARD. Thankfully plastic clips, not glued glass, but holy shit these were the toughest plastic clips ever.

Oh, on another device that's already been "dealt with" by creating a minimal DTBO that still lets the recovery work

(at this point why not try to "mask" the whole DTBO in the mainline DTB lol? that's been done for the […]

Wow this is silly.. I'm sure glad mtkclient can handle this SoC, because there's seemingly no key combo for the lk bootloader's fastboot mode. Volume down is *recovery*, volume up (at the logo stage, not early when it does enter BROM of course) is a device test menu (in Chinese even). Replacing […]

I cannot make a bespoke action plan for your exact situation, but if you feel like what you're doing is pointless, there are options.
If you need to yell about how frustrated you feel, I respect that! (Perhaps consider my well-honed spiritual practice of Hollering Into A Tree or the classic […]

Interestingly, two days before Oracle deleted my account and all servers associated with it, I publicly criticized Oracle's CEO in a viral post for promising dystopian AI surveillance technology to his investors.
