[GUIDE][alioth] How to install Xiaomi.eu ROM for Xiaomi Redmi K40

Hello :)

For this recent device, you should not "install" TWRP. Just boot TWRP via Fastboot. ;)

Here are my recommended steps:

1) Boot to stock Recovery and "Wipe Data" then directly hold " Vol - " and " Power " button simultaneously (boot in Fastboot mode)
2) Boot TWRP (do NOT flash TWRP)
3) Put Xiaomi.eu in internal storage and flash it
4) Reboot your device and voilà!

So, no need to format data?
Thank you for reply!

Hi, I wonder why not following the step as recommend installation step of the section in "MIUI 12 STABLE ROMS":
  • Code:
    fastboot flash recovery twrp.img
    fastboot boot twrp.img

May you tell the reason of DO NOT FLASH and steps to do if next update arrived?
 
@steelcow Hello,

If you try to flash TWRP via fastboot on recent devices, it will report this following error ' recovery_(a/b) - no such partition '. ;)

Recovery partition is no more! Recovery is now included in the "boot" partition. :)

Recent Xiaomi.eu ROMs, for these recent devices, already include the custom Recovery in "boot" partition.

What device do you have? New devices has some problems and it is a little different for installing twrp and custom roms.
Many people hard bricked their devices

Thank you for your explanation. Is it due to Android 11 thing? Because I have Mi 9T and flashed other custom rom before(now I revert back to orignal locked bootloader and system) and didn't hear about this error before.

And how we do the OTA when next update is arrived? Download new rom in updater and save in internal storage, boot to recovery without flash recovery, flash the new rom zip file without format data and good to go?

You can download new ROM in Updater but you need to manually boot in TWRP (hold " Vol + " and " Power " buttons simultaneously) then flash the new ROM and reboot your device. ;)

I am about to unlock bootloader in 1 hour and i want to install Eu stable rom but the current roms do not have fastboot install method so i will need to use the Alpha Twrp which concerns me. Can this version of twrp wipe and format partitions if i boot from it in the same way a recovery partition Twrp would work. And also can it flash the eu rom without issue.

Of course it can flash EU ROMs without issue. If it wasn't the case, there will be fastboot ROMs. ^^

You can follow my recommended steps => https://xiaomi.eu/community/threads...eu-rom-for-xiaomi-redmi-k40.60379/post-611429

Then please feedback if it worked for you or not. :)

Hi, I have boot TWRP, flash the zip file and reboot to system. However now it seems stuck in recovery(TWRP) and shown No OS installed, internal storage also seems empty. How to fix it?

#Edit 1: I install twrp again using install "recovery ramdisk option" and install zip file using USB OTG. Still it doesn't boot into system.

Hello,

Flash Xiaomi.eu ROM again.

If still not working then use "Format Data" button in TWRP ("Wipe" menu).

;)

You use "format data" after installation the rom or before?
So the twrp not see the internal storage but you must flash via usb otg stick?

The steps I done is :
1. Unlock bootloader
2. After phone reboot, I go to stock recovery and wipe data.
3. After phone reboot again, I boot into fastboot mode using "Vol-" and "Power" button
4. I boot the TWRP.
5. I copy xiaomi.eu V12.5.3.0 RKHCNXM zip file into the device, that time still showing internal storage and flash it via TWRP.
6. I reboot to system but stuck in Redmi Logo twice before it go to TWRP again. This time the internal storage cannot be read.
7. I flash TWRP image using USB OTG in "Settings"--->"Install Recovery Ramdisk" and reboot to recovery.
8. I install rom zip file again using USB OTG and reboot to system but end up into TWRP recovery again.
9. I use "Format Data" button in TWRP ("Wipe" Menu), now works and boot up into system after long time waiting. You will see the MIUI logo stuck for about 3 to 5 minutes if not mistaken before setup page showed up.

@Poney70 Can you tell me which step I have made is wrong?

@steelcow For the step 3 => "After phone reboot again", did your phone started to boot in system or not? If yes, that's why your internal storage was not empty in step 5. ;)

Yes, it boot into system and I also forget to logout my mi account. I only able to shutdown the phone and go to fastboot mode after I login mi account.

Also may you update the correct sequence for others to refer? At least they able to fix the error by refer correct steps...

Don't let your phone to boot into system after "Wipe Data", that was your mistake but "Format Data" in TWRP worked for you. ;)

What if I want to factory reset through TWRP? In stock, it can be access from "Settings" app and "Wipe Data" in stock recovery.
 
Poney70 said:
I never used the "Factory reset" function in TWRP. I always used "Format Data" to do a clean installation/factory reset. ;)

I've never noticied that redmi k40 has A/B partitions, i've unlocked the phone and flashed the recovery phone with the latest aplha recovery and formatted data, anyway the internal memory wasn't writable, and i've picked up a USB-C pen and trasfered the rom inside it.
I'm flashing from the USB... Before i've tried to flash the stock rom with no positive result, because the flash via fastboot takes 0s, and the fastboot flash from twrp takes over 1200s going in timeout.

Finger crossed from me :D

Edit: All worked fine, but please help me to understood, if i don't have a usb-c pen how could i exit from that "dead-end"

You'll need to download the twrp version available (this one), and rename it to «twrp.img»
then open a CMD dialog box
enter "fastboot boot twrp.img" --> twrp will be uploaded to the device (not installed), and booted
then upload the 12.5.3.0 rom to the phones memory (or use an OTG dongle with a USB stick with the rom on it)
then press install on twrp and select the new ROM

And you're done.
