Good morning everyone!
after 2 days of hard struggle, I finally installed openwrt on mine Xiaomi MI router 4A (100M Edition)!!!!
The box and the label on the bottom said it was the version: R4AC
Despite following hoddys guide i couldn't install a version of openwrt without bricking the device!
Here is the procedure (it worked for me):
-
- initial firmware version 3.0.5 (international edition because the label on the bottom and the web page were in English)
-
- downgrade to 2.18.28 then upgrade to 2.18.58 follow this post and use that program (false virus positive!):
Debrick Xiaomi Mi Router 4A
- downgrade to 2.18.28 then upgrade to 2.18.58 follow this post and use that program (false virus positive!):
-
- when you have installed version 2.18.58, make sure your router is connected to the internet and follow the hoddys guide (VirtualBox etc.):
Installing OpenWrt on the Xiaomi 4A, 4C, 3Gv2, 4Q, miWifi 3C and debrick method New 2022
- when you have installed version 2.18.58, make sure your router is connected to the internet and follow the hoddys guide (VirtualBox etc.):

- here's the main point, YOU MUST USE THE FIRMWARE FOR THE MIR4A VERSION!!! It sounds crazy, but if you look at the firmware layout you will see that the field to check (md6) is different from what is indicated in the openwrt page (https://openwrt.org/inbox/toh/xiaomi/r4ac), but it corresponds to that of the MIR4A, then I installed the firmware: https://downloads.openwrt.org/releases/22.03.2/targets/ramips/mt76x8/openwrt-22.03.2-ramips-mt76x8-xiaomi_mi-router-4a-100m-squashfs-sysupgrade.bin
found at https://openwrt.org/toh/xiaomi/mi_router_4a_mir4a_100m#flash_layout and it worked right away, with luci installed!!

I don't know if they mislabelled or whatever, obviously I don't want to have anyone on my conscience, so choose to risk it, but it worked for me.
I bought the router on December 22, 2022
