Also i think has to be in the first post of this thread, i fixed by edl then updated to 12.0.9 again by turning on auto updates by mistake hahahaTo successfully flash Xiaomi.eu "fastboot" ROMs, "update to the latest China ROM version" seems to be a bad advice for some devices... (like Mi 11 Pro, Mi 11 Ultra and so Redmi K40 Pro?)...
The only solution I know is to pay for an EDL Unbrick Service (like this one: Telegram -or- @Angeluss69) and ask them to flash a previous "China" fastboot ROM version (188.8.131.52, download link => here) and keep the bootloader unlocked.
On 184.108.40.206, finish the first setup wizard (MIUI 12 setup) then try to flash a Xiaomi.eu"fastboot" ROM again...
Dunno if I'm following the procedure correctly, but it didn't help.
What I did was basically:
Run modified script that tried switching to slot B (set_active other), it got stuck
Rebooted phone into fastboot (Power + Vol-)
Ran original script, it got stuck on switching to slot A
Yes but for me after running the rest lines nothing happensPressed ctrl+C
That's the difference!
I never did this part. Just push the buttons!
After pw+vl-, the phone get into fastboot, AND the script run the rest lines!
I stucked for two weeks.OK - LOL, I have no idea how I did that. I fixed the phone. 0_o
Just random flashing with various combinations of images resulted in it working... Don't ask me how - suddenly the behavior changed. Been doing it for like 2 days straight. I am on Xiaomi.eu V220.127.116.11. Not gonna flash the newest ROM cause I'm scared now.
Indeed, I sadly cannot write any kind of reliable step-by-step report what I did but it was a combination of flashing the latest Xiaomi.eu and Xiaomi.eu Stable. The original China ROM wasn't even involved since it was failing for me on flashing Super anyways (CRC error on Sparse).If I am right, after this, the phone boot into fastboot tokes a few more sec, and show open lock at the top.
When it happens you might succeed next flash.
I don't want to claim to be an expert, considering my problems with the fastboot ROM but the difference between the recovery and fastboot ROMs, from what I understand, is just the flashing method. That's why official ROMs also usually come in both flavors, especially the stable versions. When TWRP comes out you'll just flash the recovery partition, which won't affect all the other partitions and just switch the update method to recovery. I think the Xiaomi.eu devs will probably stop publishing fastboot ROMs at this point since in general this is a much lower level procedure with fewer safety nets and more potential for screw-ups. More screw-ups means more complaints and more support requests for the devs.Hello there,
Thank you xiaomi.eu-experts one million times for your very great work for public community.
Only short question. I have Xiaomi Redmi K40 Pro Plus.
My phone is bootloader unlocked and runs your fastboot ROM.
Can I later change to TWRP with OTA updates without loosing data on the phone?
When TWRP is released, can i still install it? Over the now installed fastboot ROM?
Is there a tutorial for that type of update/upgrade?
Thank you sincerely.
I believe I flashed Xiaomi.eu latest, it failed (on slot-switch), flashed Xiaomi.eu latest, it went through but didn't boot (Bootloader bootloop) and then I flashed Xiaomi.eu stable (same slot) and it suddenly worked... 0_o
Cool! So together with @max.ouyang 's observations we're getting close to a reliable solution to the bootloop problem. I have to admit, I managed to soft-brick my phone again after fixing it by trying to flash Xiaomi.eu 21.4.22 but also managed to unbrick it as well by using a similar procedure. I think Power + Vol- is optional, so is the slot-switching, the important thing is:I had same problem followed above
I flashed Xiaomi.eu stable on slot b, it completed but still in boot loop
Flashed Xiaomi.eu weekly on slot a, it hanged on Setting current slot to 'a' so I rebooted phone into fastboot (Power + Vol-) it finished but went to fastboot again
Then flashed Xiaomi.eu stable on slot a and it rebooted correctly into MIUI
Why it works ? ¯\_(ツ)_/¯
Anyway thanks for tip man
Don't click on the script. Open up a command prompt or powershell window with elevated privileges, navigate to the directory where the scripts are and then execute them by typing in the name.Hi Guys,
I need your Help. I boot my K40 Pro into Fastboot and Connect it to my PC with the original USB-C Cable on a USB 2.0 Port. USB Debugging is active and Bootloader is unlocked. But after i click on the windows_fastboot_update_rom.bat with Admin rights my Device didnt start the Flash procedure. The Flash Script doesnt start. Its like i did nothing. Its the same with the windows_fastboot_first_install_with_data_format.bat. I come from MIUI 18.104.22.168(RKBMIXM) Global.
I am grateful for any advice.
I tried it that way and I got the same result.Don't click on the script. Open up a command prompt or powershell window with elevated privileges, navigate to the directory where the scripts are and then execute them by typing in the name.
First things first is not having anything of importance on your new phone. If that's the case, then you can flash away and pray to the fastboot gods that it works as you will be able to unbrick eventually.Ok, so I have a freshly bought k40 pro and it's running 22.214.171.124 stable with its bootloader unlocked. Which EU rom can I flash safely? I've been reading about so many bricks in this thread and I'm scared to hell and back. Any help would be appreciated it as I haven't flashed a rom in years, I want to come back to the power user scene but Xiaomi is so different and confusing.
Your story scared me the most ngl chief :')First things first is not having anything of importance on your new phone. If that's the case, then you can flash away and pray to the fastboot gods that it works as you will be able to unbrick eventually.
My post-factum advice, considering how much time unbricking cost me (though I think we have this procedure down by now), would be: wait till TWRP is out.
I was on the latest China ROM through the updater and the first ROM I flashed was the weekly ROM, which never worked for me, even after a cycle of 2 successful flashes/unbricks. Now I'm at V126.96.36.199.RKKCNXM indeed.Your story scared me the most ngl chief :')
If I'm on 188.8.131.52 then I'm supposed to use xiaomi.eu_multi_HMK40Pro_MI11i_V184.108.40.206.RKKCNXM_v12-11-fastboot correct? Like nothing else is actually needed? Also did you flash the correct rom yourself that had a stable release before u got the brick? I was genuinely confused as to what caused yours

Generally, if your flash fails (e.g. upon swiching slots, which is what most people got hung up on according to the thread), you should still be able to go to Xiaomi.eu V18.104.22.168.RKKCNXM.
Funnily enough, I'm unable to go back to China stable anymore though.
Precautions to take, just to maximize luck:
* Use a USB 2.0 port (I used USB-C to USB-C initially)
* Run the script in an elevated prompt/PowerShell session
Other than that it's just executing the batch file and hoping for the best.
1. It was xiaomi.eu_multi_HMK40Pro_MI11i_21.4.22_v12-11-fastboot.zip and it was around a week ago. It never worked for me, even when flashing from Xiaomi.eu stable.Which exactly was the weekly rom exactly? Aren't the weekly roms only meant to be used after the eu rom is already installed or am I referring to sth else completely?
Dumb question but how exactly do I run the script in an elevated prompt/PowerShell session?
So using the official type-c to usb on one of my usb 2.0 ports on my motherboard so work just fine?
Many thanks for the replies!
