My mom has a Kindle 2nd Generation running 10.5.1 stock.
The other day, it started rebooting, but not in the traditional bootloop sense. The OS would load to the lock screen, you could swipe and use it (albeit sluggishly) for approximately 30 seconds before it rebooted again. So, it made it impossible to access the device via ADB.
I made a factory cable, accessed fastboot, and did the following:
Anyway, the more I thought about it, I thought I could clear some caches, uninstall some apks and that would resolve the issue without a new system image. Then I started to notice the problem:
I've tried sideloading in TWRP, but that resulted in a protocol fault. Also through TWRP, the factory reset succeeds, but actually does nothing. All of the data is still there. My other idea is to push the image onto the /cache partition (there's just enough room), and try to install that way, but I have a feeling that 1) won't work and 2) may exacerbate problems.
I'm stuck. Anyone have any ideas?

This worked fine. I was able to get into recovery mode with TWRP and access ADB. I pulled all the data off the /sdcard partition. This was a big concern since my mom has been using this thing for a couple years now and she's collected quite a bit. Originally, my directive was to factory reset and reflash the stock firmware from Amazon: update-kindle-10.5.1_user_5174820.bin. It would be nice if they supplied a checksum, but they don't apparently.

Both /data and /sdcard are read-only. They also use the same block device. Maybe that's normal? I've already tried remounting the partitions read-write to no avail.
Both commands execute as if they were accepted successfully (ala no output). However, rechecking mount's output, shows no change. It's still read-only.
