mjg59 | Making an Orbic Speed RC400L autoboot when USB power is attached
As I mentioned a couple of weeks ago, I've been trying to hack an Orbic Speed RC400L mobile hotspot so it'll automatically boot when power is attached. When plugged in it would flash a "Welcome" screen and then switch to a display showing the battery charging - it wouldn't show up on USB, and didn't turn on any networking. So, my initial assumption was that the bootloader was making a policy decision not to boot Linux. After getting root (as described in the previous post), I was able to cat /proc/mtd and see that partition 7 was titled "aboot". Aboot is a commonly used Android bootloader, based on Little Kernel - LK provides the hardware interface, aboot is simply an app that runs on top of it. I was able to find the source code for Quectel's aboot, which is intended to run on the same SoC that's in this hotspot, so it was relatively easy to line up a bunch of the Ghidra decompilation with actual source (top tip: find interesting strings in your decompilation and paste them into github search, and see whether you get a repo back).
