Linux being open-source doesn't mean any modification to it is easily reverse-engineerable. There is no such thing as "decompilation", only reverse-engineering, which is exactly what I referred to as "not totally impossible". However, if you hope someone to devote an enormous amount of effort just to "decompile" a kernel, you'd better off just sue the manufacturer for kernel source code (they are legally bound to do so by using the Linux kernel). It's far more plausible.

Anyway

I tried the exact same steps but ended up in a splash screen loop. Any idea how to fix this (or how to grab a log of this, if needed)?

No service on two of the sim card. Phone shows carrier, but no network.

Edited: Never mind. Start from fresh umidigi system, and all good.

TWRP keep system read only, no more boot loop.

test on Umidigi F1 Play
I make Kernel Changes to make your rom work on umidigi f1 play and it booted but a lot of issues :
- sim card doesnt recognize in second reboot
- A lot of NFC Force closes
- Sound is deteriorated (i Think it because the besloudness in the stock rom)
- Rom has a lot of features that not working (example percentage of battery is not showed after i enable it)

this just a report of 15 minutes testing roms

That would be easiest if you use twrp and make a backup , before flashing this. Same as with any rom, you should make backup first.

If you didn't do that, or the restore fails. Then use sp-flash tool and flash factory firmware.
Umidigi posts the firmware on there community web forum.

You have to put sim cards in before the initial boot. I gave up because too many bugs.
