Tl-mr6400 v5.2

I have TL-MR6400 V5.2
Can i install TL-MR6400 V5 openwrt on V5.2?Is there any problem?

Yes, v5.2 would usually be v5.

There will be no problems, Just go for v5, have tried it myself,

Just remember, I personally had lot of struggle on latest version of openwrt (22.3) as 4g modem simply doesn’t work, would advise to use openwrt 21.02.3.
