MERCUSYS MR90X V1.20 İnstallation

Hello, I want to install MERCUSYS MR90X v1.2 on my device. I need a friend to support me. First of all, it seems support as V1.0. I have a V1.20 device. Will I have problems with the installation? I also had a Tp-Link Archer AX23 V1.20 device in the same way before, it was only V1.0 supported, but I downloaded the upgrade file directly and installed it from the modem interface and it worked. However, the system was not very efficient, I was constantly encountering stuttering and errors. Now I want to use the power of this device to the fullest and make a correct installation. I would appreciate your support.
Thank you in advance.

Forum search can help you locate original device specific thread.

That would be good, really. “https://openwrt.org/toh/mercusys/mr90x_v1” I got information about the subject from this address, but it seemed a bit complicated, I could not find a link as a guide.

that's what you get, threads probably won't provide anything less complicated.
