Having trouble downgrading and older device

Hi, we are having troubles downgrading an old device to an earlier version:

currently installed:

Component Versions
Rootfs Colibri-iMX6_wolf-qt-image V1.1 20170717

Component Versions

Rootfs Colibri_iMX6_LinuxConsoleImageV2.3_20160415
  "uboot.crc": "0xfa63aa80",
  "rootfs.crc": "0x5180151d",
  "kernel.crc": "0xa1bf9931",
  "dtb.crc": "0x733e899e",

During the run setupdate process, the serial output is:

Colibri iMX6 # run setupdate

** Unable to read file flash_blk.img **

There is no flash_blk.img file in the files for the downgrade. Can we still downgrade the device?

Hi @hankorts and Welcome to the Toradex Community!

You need to put the module in Recovery Mode and run the update.sh script (from Bsp 2.3) with -d option as described here.

Best regards,
