Hi, does it mean I can now safely buy either version?
No, I was talking about the RB03 (Chinese version), that one is expected to have telnet enable after flashing the closed beta firmware, what I failed to realise was that the webui endpoint does not update and the router actually uses port 23 for telnet.
Rc2 is ready.
Anyone has installed it?
Installed 10 min ago hahaha
And so far, everything works fine.
Yes, just updated from RC1. So far it works.
Also a note: Got two international versions Mi Router AX3200, both with telnet unlocked
Model: RB01
Production date: 08/2021
Bought from different stores in Bulgaria. Also there was one in the Xiaomi Store with the same production date. One of the suppliers stated that those are from the last batch, I don't know if that is true.
Rc3 started building...
Hello,
I find OpenWRT an awesome project and the Devs did a great job with adding support for this device!
My RB03 device finally arrived and i have tried several snapshots, including rc3:
openwrt-mediatek-mt7622-xiaomi_redmi-router-ax6s-squashfs-factory.bin
openwrt-22.03.0-rc3-mediatek-mt7622-xiaomi_redmi-router-ax6s-squashfs-factory.bin
openwrt-22.03-snapshot-r19381-b42511c007-mediatek-mt7622-xiaomi_redmi-router-ax6s-squashfs-factory.bin - currently using this one (OpenWrt 22.03-SNAPSHOT r19381-b42511c007 / LuCI openwrt-22.03 branch git-22.140.66268-ef99568)
With each one though i get the same issue - the 5G wifi driver doesn't seem to start:

And i don't get to see a wlan1 interface. On the stock firmware both wifi radios worked. I haven't seen anyone mention such an issue and any hints for solving this are appreciated!
Thanks!
try rc1. it has been very stable for me.

Set a wireless region for the 5G radio
Hello,
I have installed rc1, but no luck - still seeing same driver issue in dmesg, hence only radio0 (MediaTek MT7622 802.11bgn) is showing in Luci.
Then i downloaded https://github.com/openwrt/mt76/blob/master/firmware/mt7915_eeprom.bin and reloaded the kernel module:
cp /tmp/mt7915_eeprom.bin /lib/firmware/mediatek/
rmmod /lib/modules/5.10.111/mt7915e.ko
insmod mt7915e
dmesg | tail

Now i have also radio1 (MediaTek MT7915E 802.11nacax) in Luci!

Is the 27db (500mW) limit a hardware one or is there a reason why it can't do the whole 30db (1W) but my Archer can?
Judging from the FCC measurements of common consumer devices, you'd be hard pressed to find any devices that would even get close to transmitting 1 watt over the air.

I believe they're more euro-centric for their global products, so the best you have in that regard is a declaration of conformity, with the actual test reports only mentioned by report number.
For the US market, they haven't submitted many of the product line to the FCC (I think I saw the 4A in there...). I assume that's fine since they're probably not direct selling them to the US market.
They can be shipped worldwide if you buy on AliExpress. I hope it's legal to have them shipped here. 
At the present moment (April 2022) there is no known way to enable telnet on the Xiaomi AX3200 (model RB01, international version). So if you have this device, you can check if it came from factory with telnet enabled. If so you can install OpenWrt, otherwise it is not possible to install OpenWrt on the Xiaomi AX3200 (model RB01).
I couldn't find anything related to this in the thread, so I apologize if this is a redundant question. But just to make sure: wouldn't I be able to bypass this restriction by soldering pins to the serial pins and use that to login as root? Or is there no active serial console on those pins?
Im using vnStat to monitor bandwidth and I think monitoring doesn't work correctly on this device, is that because NAT Offloading is enabled ? I selected wan interface and it detects about 30% of real bandwidth. Anyone else using vnstat ?
as @cliobrando quoted, you are able to install OpenWrt if you have serial access.
And you don't even need to open the case, if you have long enough pins ...:

Got a November 2021 RB03 (running 1.0.19) and successfully installed OpenWRT yesterday. Be warned though that the web UI is Chinese with seemingly no way to switch to English.
I used DeepL and a lot of guessing to flash the beta firmware to get telnet access after which it was smooth sailing (well except for the part were my existing network already uses 192.168.1.1 as gateway 
)
