Insert USB drive in your computer.
You need to format it in FAT32 with 4096 allocation size (or exFAT on some USB drives).
Copy .img firmware file you want to restore to the root of your USB drive and remove it from your computer.

Warning

Make sure there is no other file present on the USB drive except the firmware file.
Turn on the printer.
Once you are on home screen, plug USB drive on the front of the printer.
Connect to SSH (Guide is available here) and run this command:
```
/etc/ota_bin/local_ota_update.sh /tmp/udisk/sda1/*.img
```
You should see the progress status in the console.
When the process is complete, just turn off the printer and turn it back on to boot into the new firmware.
Then, follow this Reset Factory Settings section to restore default settings.

Warning

After a factory reset, all features already been installed with Helper Script for Creality must be reinstalled and root access needs to be re-enabled from screen settings.
