Boot loop after trying to downgrade EU stable 11.0.2 to EU stable 10.13.17

TL;DR - Tried to downgrade Android 10 Xiaomi EU to Android 9 Xiaomi EU, tried wiping the device (besides storage). I can get into TWRP and Fastboot, just won't boot OS.
Detailed:
I was running the latest Android 10 Xiaomi EU Stable Rom MIUI 11 (11.0.2) and wanted to downgrade because I had a few issues.
I reinstalled the last stable Android 10 Xiaomi EU Stable Rom for MIUI 10 (10.3.17) and it ran fine. I then realized that I wanted to be back on Android 9....
I went and tried to install Android 9 Xiaomi EU Stable Rom for MIUI 10 (10.3.16) and then ran into boot looping.
So then I got into TWRP and erased all data and then tried to copy over the old update file and realized I can't copy over anything even with MTP Enabled.
All the folders in the sdcard are random letters and numbers..
So now I can't send any files over and im stuck wondering how to fix this problem and then go over to Pixel Experience.
Send help! Please!

You messed up with encryptions... Just flash Chinese fastboot rom before pixel experience... and, as always, don't forget: DO NOT lock your bootloader ..

And I would do that by downloading which version of fastboot? Any stable one that I want to run?
Also would it be through fastboot using Mi Flash Tool or something else?
Then the pixel experience would be installed just through TWRP?
Sorry, I just don't wanna mess up.

As you want to flash pixel experience, you need to flash chinese fastboot rom, because pixel experience is based on Chinese firmware. So, by flashing Chinese you will be half way. Pick last stable pie version.. I believe is 10.3.16, don't remember...
Yes. You should use miflash tool, just don't forget: you need to select "clean all" and not "clean all and lock".
Boot into miui system once.
After that just flash twrp through normal fastboot command, as you already did in the past. Then flash PE in twrp...
Remember to boot in twrp just after flash it, if you boot into device it will be replaced by stock one...

After booting into TWRP and before flashing PE, wipe cache and dalvik, then format data. Either reboot into TWRP, or unmount and mount data, then carry on with the PE flashing.

@Robbo.5000
That sounds confusing..
So after flashing the chinese fastboot and starting the phone up once to confirm its working, i boot into twrp and wipe cache+dalvik, then format all data, then restart into twrp and flash pe?
Doing that is just making sure its a clean flash and not a dirty one?

You boot into MIUI once to let it finalise the installation.
Then install TWRP and immediately boot into TWRP.
When changing ROMs you should clean flash, which normally means wiping cache, dalvik and data before installing the new ROM.
In this case it's best to format data instead, otherwise you may get problems with encryption, similar to what your seeing now.
After formatting data, TWRP sometimes has a problem seeing the data partition properly, to fix this you either reboot into TWRP or go to the mount menu and unmount data, then mount it again.
After this you copy the PE ROM onto the phone and flash it.

More details needed if you want some help or all you wanted is some condolence?
P.S. If you don't know what details, just describe what actions have been taken I was on ROM x versions x.x.x with TWRP x, how you flashed MIUI11 and what MIUI11 ROM and version you used.

TWRP version is: 3.3.1-42
I was on original rom and I used this rom: xiaomi.eu_multi_MI9_V11.0.2.0.QFACNXM_v11-10
Procedure: I wiped dalvik/ART cahce, cache, System Data and then installed the rom and rebooted and I am now in bootloop.

P.S I have global version

Does your TWRP successfully decrypt data now? Do you have access to files in TWRP? Or you just see strange names.
If that is the case, just format data, it's an option in wipe menu. And then reflash ROM.
btw wiping system is not needed and useless.

Decrypts successfully because i install rom from internal storage and still it doesnt help.

Then everything should work, try to read this thread: https://xiaomi.eu/community/threads/miui-11-0-stable-release.52628/ , may be you not the only one.
But i would try format data any way. Format will remove everything and will create a fresh unecrypted file system. Wipe only delete files.
If it won't help you may try to flash fastboot ROM, and then format and etc.
btw When you wipe cache/dalvik, it takes some time to boot, it can be 5-10 minutes.

Unable to install custom roms

Hi all,
I was on xiaomi.eu MIUI 11 ROM for some time, but wanted to switch to either Evolution or Syberia ROM.
I did a complete wipe and installed evolution os trough twrp... but i forgot to remove encryption so i bricked my device...
So then, I flashed the latest stock rom (11.05)with Xiaomi flash tool, but then i was stuck with the chinese ROM so...
1. I went back to bootloader and flashed mauronofrio's TWRP recovery .
2. completely wiped phone; Cache,System,Data,Internal storage
3. copied Evolution OS 4.1 to my phone
4. installed zip trough TWRP, all successfull
5. but then when rebooting, TWRP says:"No OS installed, do you wish to continue"
6. i tried other ROMs like xiaomi.eu and syberia, but these would either give me the same problem, or just bootloop until iam back in the fastboot screen...
Anyone any idea what iam doing wrong?

This works for me every time.
1 Flash the latest fastboot ROM.
2 Flash TWRP (same one you used)
3 Boot into TWRP (use the vol+ button when booting)
4 In format menu swipe to factory reset, then format data (VERY IMPORTANT this must be FORMAT not just wipe)
5 In reboot menu boot into recovery, this ensures TWRP correctly accesses the newly formatted data partition.
6 Copy over the ROM (and GApps, if needed and/or Magisk)
7 Flash the ROM, (then GApps if needed)
8 Boot into system and do the initial setup
9 If installing Magisk, boot back to TWRP and install Magisk.
There is no need to wipe anything else. There is no need to wipe anything again after installing. There is no need to disable encryption or dm-verity.

thanks, i always thought that a wipe was sufficient, or at least equal to a format... anyways will report back later when i have time to try it. lets hope it works because i can't handle this chinese rom

The format is needed to temporarily remove encryption
I've just remembered that I missed an important step. Call it step 1.5
If you going to flash immediately after flashing official MIUI you must boot into MIUI once before doing anything else. You don't need to go through the set-up, you can boot immediately into fastboot after you get to the initial set-up page. The first boot finalises the install and is needed before you flash over the top of it. That may be the cause of your issue if you had missed this before.

Ok so i flashed TWRP again, rebooted to stock rom and then rebooted into recovery, but the stock recovery is still there.
When i flash TWRP and reboot into recovery immediately i can enter TWRP, but if i reboot the phone to MIUI and then reboot again, TWRP is gone again...
It seems like TWRP does not persist... now iam stuck again on fastboot screen because i wiped + formatted everything.
Edit:
When i want to flash recovery it says "OKAY" but it is unable to boot:
Sending 'recovery' (65536 KB) OKAY [ 1.562s]
Writing 'recovery' OKAY [ 0.333s]
Finished. Total time: 1.989s
Sending 'boot.img' (65536 KB) OKAY [ 1.547s]
Booting FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
fastboot: error: Command failed

This is normal, MIUI will restore stock recovery of the recovery partition changes. In order to persist TWRP you need to either install Magisk, disable dm-verity or install a custom ROM.
If you are going to flash a custom ROM, then you should do so immediately after flashing TWRP.
After formatting data, TWRP has an issue seeing the data partition, so go to the reboot menu in TWRP and select to reboot to recovery.
Then you can immediately install the ROM of choice. You cannot boot back into system as you'll lose TWRP.

Ok, it appears that everytime i wipe system, i am not able to boot anymore into TWRP... Am i supposed to wipe System? or only wipe data & format data

There is no need to wipe system. You only need to wipe cache and dalvik and format data. (I choose to factory reset because it's easier in TWRP, but you could do advanced wipe and select cache and dalvik, then format data. Follow the steps exactly, but include my later step 1.5
I've just followed this myself today, as I've moved from LOS to the latest unofficial Havoc build.
In theory you could start by booting to fastboot and flashing TWRP again, then follow the steps from that point. You probably don't need to install MIUI.

Ok thanks a lot! So no need to wipe system partition after stock rom install. just wipe cache/dalvik/data, got it.
Most ROM install guides tell you to wipe /system when coming from stock rom. I guess this requirement has changed? or depends on what ROM you're coming from?

I need help... The reason why I'm flashing custom rom is, when the latest update came MIUI 12.5 android 11, all sensors of my phone stopped working like (Gyroscope, accelerometer, proximity sensor) I tied to flash the rom by fastboot method but still the problem persists. because of that I unlocked bootloader and flashed twrp. After flashing custom rom when I tried to boot it, it stuck on booting screen and when I tried to reboot into recovey it is showing fastboot mode. I'm unable to boot into custom rom.

Fastboot after wiping everything in Twrp.

Hello, when i install new rom i format data, wipe everything in twrp then i install rom(im mainly using ones with oss vendor) and dfe and phone just goes fastboot logo. When i uncheck system partition everything is fine. Is there someone that knows how to wipe system partition without going fastboot.

Don't wipe system, it's not needed. Doing the factory reset in TWRP wipes everything that's need to be wiped for a clean flash.

Stuck at MI Logo...

Hello all,
so i have an strange issue here. after installing magisk canary yesterday evening, i ended up in a bootloop.
so i stayed pretty cool and went to twrp, used magisk uninstaller and thought hmm okay ****, still not booting, not even shows the boot animation now.
stuck at the MI logo, flicks one time, and then stuck again.
so trying to reflash magisk then with 20.4, but nothing changed.
i ended up doing a full wipe, downloading the latest v12 vendor global and reflashed the rom.
booted up all fine. set it all up again, did a random restart, without doing stuff.
boot animation....10 minutes..
restarted stuck at mi logo again.
not even the system is trying to get up.
now i can wipe verything, vendor, data, system, dalvik, whatsoever, i wiped everything, flashed vendor again, installed rom.
nothing... stuck at the MI logo.
any ideas?
many thanks

If you're flashing recovery ROM i suggest you use fastboot ROM

i reflashed now via xiami flash tool and stock rom and it boots up.
but as soon as i flash twrp and a custom rom, with wipe before, everything is stuck again on the mi logo.

From stock MIUI.
Install TWRP
Boot into TWRP
Do a factory reset
Format data - Format not wipe, need to type yes to confirm
Reboot to recovery (TWRP)
Flash custom ROM
Flash GApps if needed/wanted
Boot into the ROM
Everything should be good
Flash Magisk if required
Do not wipe any other partitions in TWRP, the factory reset is enough.
Make sure you format data in TWRP - don't miss this step out.
If you're doing this immediately after flashing MIUI, you must boot into MIUI once to finalise the installation.

Yes format data not wipe.
when i flash custom rom, even i am not on miui i first format data with yes in twrp then reboot to twrp. I put rom and gapps to internal memory, and install rom and gapps. and when finish reboot to system, when phone restart it stack at mi logo, so i have to go back to twrp and do again format data with typing yes, and then reboot to system and it works. so no wipe data, format data with typing yes.

oh and i thought, wipe is the same as format.... :/
works like charm. booted up successfully evo x with vendor 12 global.
Install TWRP
Boot into TWRP
Do a factory reset
Format data - Format not wipe, need to type yes to confirm
Reboot to recovery (TWRP)
Flash Vendor
Flash custom ROM
Boot into the ROM
Everything should be good
Flash Magisk if required
thanks all !

If you want to change to a different ROM, or if you want to update Evo x, then the safest way is to remove lockscreen security before flashing. This will remove encryption, which will allow you to clean flash a new ROM, or dirty flash an update, without any issues caused by encryption.
Once your done, add the lockscreen security back.
