Hi, someone says XR500 is similar to R7800. Is it possibile to make a XR500's firmware for R7800?

It looks really similar but without physical access it is really hard
The official firmware of R7800 and XR500 is universal, so...
Well,most likely Netgear is rolling one with multiple dtb-s packed in.
So they simply boot from different config than R7800.
If you have a bootlog we can inspect that
Sorry, I didn't bootlog, but I saw tests on the China forum that showed the wireless performance of the XR500 is not as good as the R7800, so I recommend that those who want to buy it should choose the R7800.
