Hi everyone,
So a couple days ago I was using my winterbreak-jailbroken kindle paperwhite 3 just fine, when I decided to install a few packages using my own port of pip. Then, some packages later, it stopped on an error saying "no space left on the device." I ran df on the /mnt/us partition, but it still had 2gb left, so I (stupidly) assumed it was nothing. However, a couple hours later it hung on the "swipe to unlock" screen, so I was forced to reboot. However, after that, it hung on the white boot screen with the kindle logo and the person under the tree. I tried having it stay on that screen overnight and also drain the battery, but none worked. I also tried mounting the partition, but it didn't appear upon running lsblk with a file-transferring cable. Now that I think about it, pip installs its downloads in ~/.cache/pip, which is in the /tmp/root (or /var/tmp/root?) directory, a separate partition from /mnt/us and I was stupid to assume it was OK that the /mnt/us partition was good.

I think that's the root cause of the fact that it's stuck on the boot screen, since that's all I did, but it could be something else?
Any help would be appreciated!
