Mikrotik bootloader questions

The page https://openwrt.org/toh/mikrotik/common contraditcs itslef.

OpenWrt is not compatible with the bootloader of RouterOS v7 or v6.46 or above. Do NOT upgrade the firmware on your device past RouterOS v6.45.8 or, if you did, downgrade to RouterOS Firmware v6.45.8 or earlier before installing OpenWrt.

Yet the section on how to do this says:

bootloader from RouterOS v7 is not compatible with OpenWrt … downgrade to RouterOS v6 …
If the version is below 7, you are all set. If it is 7.*, downgrade RouterOS to v6 before proceeding. 

Which is it?

I tried to downgrade as per openwrt instructions:

[admin@RouterOS] > /system routerboard print
       routerboard: yes
        board-name: hAP ac lite
             model: RB952Ui-5ac2nD
          revision: r2
     firmware-type: qca9531L
  factory-firmware: 6.48.6
  current-firmware: 6.48.6
  upgrade-firmware: 6.45.8

It suggest I won't get the bootloader to 6.45.x, whilst:

[admin@RouterOS] > /system resource print

indicates the factory software to be 6.44.x

Totally confused :face_with_spiral_eyes: :dizzy_face:

I'd like to get openwrt on RB952Ui-5ac2nD (hAP ac lite)


You just leaked your serial number
