The other OTA updater is in the 'main' system.
You can just mount the rootfs image from an Amazon update package and study it.

But before you waste too much of your lifetime on all of that -
Think this through:
"If we (or you) could write something to the device's storage, don't you think we would just write the 250 byte signature certificate and be done with it all?"
(Which is what coplate said above - if we could write a new u-boot, then we could also write a new (our) signature certificate.)

I you shure ?
In my voyage when I put in recovery uboot mode I can't load mmc image file from usb storage - " command '3' unknown " so I supose this function is disable in my u-boot version.
And fw 5.8.10 don't have diagnostic kernel : command bootm 0xE41000 load kernel but stuck in init : partition with init file missing
I would like to know the steps to load uimage and u-boot from file to mmc space using fastboot and serial cable because I did not find a clear description (the github is a description but for PW not KV and no image files for KV) I'm using mac mini myself, but I have no way to compile the software on it
