CT3003 upgrade failure and how to restore original

Hi all,

I try to upgrade a CT3003 bit failure and how can I restore to original?

Directions are in the git commit.

Hopefully you followed this (before you tried to install OpenWrt):

If you plan to recovery the stock firmware in the future, it's advisable
to connect the device via the serial port and enter failsafe mode to
back up all the MTD partitions before proceeding the steps above.
