I updated an older Raspbian Jessie image (imaged around April/May of 2016) using sudo apt-get update && sudo apt-get dist-upgrade -y, followed by an sudo rpi-update straight after. This is on an RPi 2 B. A reboot resulted in a quickly flashing boot screen with 4 Raspberries, followed by a reboot, ad infinitum.

Is there any way I can get this image back to working order, without starting over? I've looked in `/boot' but cannot see older kernel images or anything I can switch to. Any other tips on where I should look to find the fault in the boot sequence (e.g. a log file or something) would be much appreciated as well.

  • ouch. I thought I needed that to get a pre-3B firmware upgraded to a 3B firmware. This SD card needs to work in both 2Bs as well as 3Bs, hence why. – Phil B. Nov 2 '16 at 10:35
  • Well, it wasn't rpi-update. Was able to get into the same infinite boot loop with another image that hadn't had a update && dist-upgrade in a few months. Guess I'll have to start fresh and reconfigure my image. I tried copying /boot and /lib/modules /lib/modprobe.d over from a working Jessie to the bricked one but that didn't help. – Phil B.
