Recover Raspberry Pi From Corrupt kernal.img
This issue seems to happen often on the rpicam device in the kitchen. The green light will flash 7 times on boot when the kernal.img is corrupt from the device not being shut down cleanly. I found these instructions to recover the sd card in this case. It involves booting the pi with a new sd card loaded with raspbian, put the corrupt sd card in a USB adapter, find the corrupt devices in /dev/* (found mine in /dev/sda6 and /dev/sda7). This is based on the post from wvk here: https://forums.raspberrypi.com/viewtopic.php?t=178357 First I found the dev paths to /boot and /root on the currupt card Before inserting the usb adapter with corrupt card: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/root 59G 11G 46G 19% / devtmpfs 333M 0 333M 0% /dev tmpfs 462M 0 462M 0% /dev/shm tmpfs 185M 816K 184M 1% /run tmpfs 5.0M 4.0K 5.0M 1% /run/lock /dev/mmcblk0p1 253M 49M 204M 20% /boot tmpfs 93M 24...
