my build host has gone offline
theoretically it is still running the build
vast.ai says i won't be charged while it is offline
i'm worried, however, that if i just let it do it's thing, i will
forget it is there, and then when it comes back online i will be
charged a lot.
reminding myself that the build instructions page links to a telegram
community to find the most up-to-date steps

the latest release boots. i can switch to the tip sources, and look
into other phones.
oh it was their fancy splash image
v310 worked fine
v313 is just showing me a picture from a donald duck comic on boot ...
so, i tried android 11, v301, and it actually booted !!
maybe when i tried last time i just hadn't done the 'flashing unlock' command
i can totally use newer git trees than i am.
back to bisecting release versions ...
it seems like it would make sense to build the tip release
since i have little experience building android roms
then of course i could bisect backward to see what changes are
associated with what issues
the builds are generic, not for a specific phone

I never figured out mtkclient, unfortunately. I never even got in
communication with one of the devs or users.
However, I've got all the v2xx phhusson treble builds booting on the
device using fastboot, which is great stability on that front. Even
running a rooted phone at all would be a step up

I've written code to parse the download agent firmware for the different
mediatek phones and dumped the chip id -> platform table used to index the
firmware.
It was difficult to do the table dumping. If I've ever written a patcher
before, it was a very very long time ago. It
My work on this is paused and is at
https://github.com/xloem/backyard_mediatek_flasher , where the relevent
commands are noted as comments in test.py as I reviewed strace logs.
The next step is probably to figure out how to extract the download agent
firmware from its binary file, and optionally

I came back to this project and it wasn't working any more. The phone was
just echoing the handshake byte.
I thought I'd run the mediatek flasher and use stty to capture the serial
settings, in case they had changed, but it wouldn't flash either.
It said I needed to remove the

i'm looking at the disassembly around the ioctl calls using gdb.
the object actually has debugging symbols, so functions are named.
it looks like ioctl is called by passing arguments on registers (fastcall?)
here. the first argument is in edi, fd 13. esi, edx, and eax are also set.

I used the linux tool to read back some bytes and it looks like the device
has a normal dos/mbr partition table, which is cool given all the scatter

eventually I found from
https://www.rigacci.org/wiki/doku.php/doc/appunti/android/sp_flash_tool
that the flasher is available for linux (binary only). if it works with my
glibc, this could make it much easier to work with.
I also took a usb log of the windows flasher using usbpcap. unfortunate
when I tried 'fastboot flashing unlock' it said I needed to enable oem
bootloader unlocking.
I booted into a factory rom and did this under developer settings, doing
the dance of repeatedly tapping the build number.
maybe this was why it wouldn't boot with partition changes?
it's 1414 and it
- the factory flash tool needs the device to be plugged in _after_ it scans
or starts
- the scatter file it uses is basically just a list of mappings between
filenames and partitions: or at least, it performs uploads if I treat it
that way

if I let them all download on their own I should move the download to a

when I flash it says "not allowed in locked state"

the phone came out dec 2019, which is also the month of the first tag, so

thankfully, it powered back up.
