+## Creating a backup

+You should create a backup of the `bios` region. Then, in case something goes wrong, you'll be able to just flash it back externally.
+
+The `me` region is locked, so an attempt to create a full backup will end with a `Transaction error!`. But you still can back up the `bios`:
+```
+sudo flashrom -p internal -r bios_backup.rom --ifd -i bios

+## Flashing the backup back
+If you have created a backup and need to flash it back, do this:
+```
+sudo flashrom -p <YOUR_PROGRAMMER> -w bios_backup.rom --ifd -i bios
+```
+**Caution:** DO NOT flash the whole backup, because it has `FF`s instead of `fd` and `me` and it will brick your device. Use `--ifd -i bios`.
