| There are multiple versions of the Xiaomi Mi Router 4A, International and Chinese and the method used to install OpenWRT differs. The SKU printed on the box differs according to the year of manufacture.

| | |
| | ***Note2*** You can check mtd partitions of your router yourself by using commands "''cat /proc/mtd''" and "''dmesg''". Refer to [[https://www.mail-archive.com/kernelnewbies@nl.linux.org/msg02774.html|this link]]. |
