Lightweight Live Linux That Boots on a Chromebook?

Hello,

So I had a Chromebook (Bobba/Acer 311) with Windows running for quite a while (more than a year, maybe two), I also had that audio driver that I got from Patreon, I believe. For some reason my SD card reader just wasn’t showing anything when I put cards in, so I downloaded a driver again, I just googled the device ID and downloaded from some driver site, it was “from HP”, and the installer looked legit. It installed and then asked me to restart, which I did, but then I got the rabbit screen trying to boot over and over, the usual spining load basically goes into restarting the notebook, over and over again, until I power it down by pressing the power button. I tried making linux bootable USB, first Lubuntu, but then I read Ubuntu is not supported somehow, and then Pop-OS, but neither worked, I tried mutiple times with Rufus, MBR and GPT, and it won’t boot (sometimes it says booting in insecure mode, sometimes it says nothing, just goes into a black screen and nothing ever happens).

At this point I just want to access my files, it hassome code from work in it that I didn’t commit, because I was organizing it first, around two weeks of work, and I gotta ship this project this week. I have no idea what could have happened, can the Mr Rabbit boot thing gone haywyre? It looks normal, but it won’t boot into Windows, also I have no idea if it can boot into Linux, I was hoping I would be able to access my files on a live Linux running from USB but I have no idea of what to do now. I was also looking at the recovery process to get it back to Chrome OS and somehow it seems it only works on Linux, am I missing something? Is my device bricked? I believe I do have the ROM backup, just no idea on how to use it, since I can’t make it boot into anything

Today I was able to make it boot to Arch Linux, I just created a USB with Rufus in DD mode. The problem is, Arch has no live OS I can run to recover my files. What would be an alternative (the USB stick I have here only has 2 GB so that also sucks) that boots like Arch but actually allows me to access my files?

I was able to load the menu for ArchBang, which apparently should have a live OS mode, but everytime I try to load the OS it gives me some timeout error after a few seconds… I have no idea what’s going on anymore. I thought the problem could be the eMMC storage, but it’s also unable to boot from USB, so I think the problem might be on the MrChromebox firmware, most likely it got corrupted… Is there anyway I can try to restore it or just restore the factory firmware?

I also wanted to change the title again to highlight the problem with the firmware but i wasn’t aware I wouldn’t be able to do that anymore :0
