You can download it directly from hackpascual's web who is the actual creator of the breed bootloader.
I tried that, but as @db260179 stated, it doesn't boot.
The lan ports do get initialised,but that's about it.
No ip address is set.
The reset button also does nothing.
The tftpd tool doesn't work right om the stock bootloader,no matter which recovery firmware i use(gets transferred ok,but never flashes it)
Reflashing the backup with ch342 programmer is easy,but wanted to try to get breed working.
On the bootloader web api?
No, on the System,Backup/Flash firmware page 
In your case,select Bootloader in Save MTDBlock contents.
I guess that´s the openwrt firmware.
I didn´t flash it, because the breed bootloader doesn't respond with this procedure:
Turn off the router. Press and hold the reset button on the back. Then plug back in, wait a minute or so, then, on your pc/laptop make sure to set a static ip address to: 192.168.1.2, then connect to the router and ping 192.168.1.1, if responds then the web ui for the breed bootloader is there and you can open a web browser to http://192.168.1.1. then backup the firmware etc.
If not then, xiaomi have restricted that usage?
Ok, thanks for checking for me.
Seems like the breed bootloader Xiaomi uses doesn't have a web interface.
Too bad, that would have been a lot easier to recover the router in case of a soft brick.
But the good news, is im working on a u-boot bootloader with the web interface recovery!
More on this soon....

I've flashed that one http://cdn.awsde0-fusion.fds.api.mi-img.com/xiaoqiang/rom/r4a/miwifi_r4a_all_03233_3.0.24_INT.bin via TFTP using bootloader recovery in international version.
I tried using OpenVPN in our router it's actually 5mbps higher, based on this graph it's only 20mbps in mt7621 https://openwrt.org/docs/guide-user/services/vpn/openvpn/performance
Any ideas how to tweak this to make it higher? I'm using my own OpenVPN server in my Amazon VPS
Try UDP openvpn instead of TCP, should be faster. If you already tried and it didn't get better, try wireguard, should be less CPU intensive and work better (also openvpn is single threaded I believe, so wireguard usually works best anyway).
If that doesn't work, there may be traffic shaping from your ISP, try other ports such as 443 (TCP or UDP) if it's available.

That's max for openvpn, you won't get any better.
On wireguard you should be able to get around 200-220mbit/s on Mi4AG.
Doesn´t it do that with curl or something...
No, it uses mtd for that.
But, since @db260179 is working on a new bootloader with a web interface, don't bother.
I'll wait till there is a test version of that ready 
Hi.
I bought a Global 4A Gigabit Global last week.
I always compiled my own firmwares on my previous routers (Tplink) but for this Xiaomi, I am not feeling safe.
What is the purpose of this bootloader?
It hard to revert to stock in case of brick?
It is not possible to use a TTL adapter to stop bootloader and flash using Telnet or TFTP like olders tplink routers?
These informations are not clear to me yet.
Thanks in advance for any help.

Is anyone here tried to compile SSR plus+ in MIR4AG?
this one https://github.com/awesome-openwrt/app-ssr-plus
this is better and faster than openvpn more lightweight and secure,my friend have one he is using v2ray vmess with it but in a different router
Correct me if I am wrong but:
Ad1 Stock bootloader allows only to load official firmware using TFTP - so no "easy" recovery yet
Ad2 See Ad1 - it sometimes quite picky
Ad3 Nope, not the stock one - you need to use CH341 programmer to set delay - but at least you can see how it is booting etc.
Is OpenWrt going to release the official 21.02 next to 19.07.7? so there will be no 19.07.8? i think they will include MIR4AGE there officially am i right?
21.02 replaced 18.06
Last few tests for my new unlocked u-boot bootloader for this router.
Like the breed bootloader you can now press the reset button and go to the web page on http://192.168.1.1 and upload the firmware again.
No need for a usb serial lead etc.
Other features are:
- Add netconsole feature - you can nc to router ip address and run u-boot commands
- Fully unlocked u-boot with source code - no lock outs or verification needed, you can install oem(unpacked and rebuilt version) and openwrt firmware and swap to both with ease.
Output from me pressing the reset button on power on.
RESET button pressed!
## Enter to Rescue Mode (manual) ##
NetTxPacket = 0x87FE4B80
KSEG1ADDR(NetTxPacket) = 0xA7FE4B80
NetLoopHttpd,call eth_halt !
Trying eth2
ETH_STATE_ACTIVE!!
HTTP server is starting at IP: 192.168.1.1
HTTP server is ready!
Keep an eye on this thread, near release...

I have one question in regards of your openwrt 1.5.2, behind the software tab there is no space available to install software. I imagine it's because it have already installed adblock, bandwith Monitor, openvpn, Ddns, and others. It doesn't make much sense to have the option to be able to load software from the official repositories if there is no space left and we don't have a USB to expand the system either. Please can you release a version with just luci installed to be able load other packages. Thanks
