Big problems after bootloop

Hi all
Unfortunately, I'm having serious problems with my new Mi8, which arrived yesterday. It arrived with Global ROM and opened Bootloader.
Switch On, set up, data from the Mi6 pulled by NFC, all tutti. the Mi account I have connected here too.
Then I wanted to play the xiaomi.eu. TWRP installed via "Minimal adb and fastboot", installed via TWRP then the xiaomi.eu-ROM (newest). Has also worked. When setting up the point that I can play back via NFC what was not displayed, or I have overlooked him. Okay, again from the beginning, I thought. Have then reset the phone to factory settings to repeat the device.
Then the phone stuck in the bootloop. Again and again the Mi logo appeared and "unlocked", disappeared and came back, disappeared and came back. I did not get into the TWRP anymore, just into the fastboot.
On advice of different users on FB and another forum I should flash the Global ROM again over the MiFlash tool, which I did then also. Unfortunately I carelessly chose "Flash-and-Lock" and closed the boot loader. Unfortunately, this flash did not work and the phone now only starts in recovery mode 3.0
Due to the closed boot loader, it is not possible for me to install TWRP again, to flash another ROM with MiFlashTool. Also, the Unlock tool does not work, because I get the error message that the device is not linked to my account. I have also tried to install a recovery mod on the Xiaomi PC suite, as the bar remains on the PC but at 0%, on the phone remains the image with the pictured Mi8, after I in the recovery menu "Connect with MiAssistent "selected. Otherwise nothing happens.
With the latest version of the PC suite flashing works, but still boots the box in the recovery mode and the red font remains. Another user in the other forum said that I need the CN version, because on the CN device no EU-Rome is allowed. The CN version is rejected by the PC suite not get verified.
What else can I do. Do you have an idea that helps me getting the phone back on track?

This, for me, is the biggest joke of Xiaomi! Many users are getting stuck in this new policy! That does not exist! A total lack of respect for brand lovers. Let the developers figure out how to reverse this.

try CN Dev version, is latest and best,
forget xiaomi.eu rom lol, almost all they do you can do by yourself within minutes, uninstalling few chinese apps and get google works with googleinstaller_v3. and dev rom have root. just suggestion.

I tried the last cn-version, but the pc-suite dont verify this ROM and dont flash it.

Miflasher dont work, because the bootloader is locked.

To OP and the issue at hand, have you tried the fastboot image to install chinese stable or developer rom? That should flash and allow you to unlock bootloader again.
To the people whining about this policy of Xiaomi, you are buying a product for a different market. There is nothing wrong with their policy and you should wait for global version of the phone if you want global image with locked bootloader. It's a little like complaining that the chinese MMO you play over vpn doesn't have english menus. Well no, it's not for that market.

I tried only the chinese recovery rom for flashing with the pc-suite. The fastboot image, I can only flash with twrp or miflashtool, right? TWRP dont work, I cant boot in it. And miflashtool says, as I tried to flash the global rom, that it isnt allowed to erase a locked device.

Nah, the fastboot image flashes best in my experience if you unpack it, all the way. You will get some folders and .bat files. make sure you have fastboot in either PATH or same directory make sure fastboot detects the image and after that run the flash_all.bat and it should flash it.

That dont work, because the bootloader is locked. Fastboot says too, that it isnt allowed because the lock, same when I try to install twrp on the locked phone.

Hard brick never seen! Mia2 -> mi6x System has been destroyed

Hi. Well I speak Spanish and I used the Google translator.
Well here is my dilemma. I had my Mi A2 with Miui 10, root and twrp. I download from xiaomi.eu la rom 10.3.14 for Mi6x and the i try to falsh but i didn't delete the folder firmware update. (I do not know if it matters) when I power on the phone remains in boot loop. I did not have access to the recovery or twrp. (vol + + pwr) only to fastboot mode. The Mi Flash program error with the original rom of Mia2 (android one) and the rom mi6x (miui 10). And touching blocking the bootloader. From there I see "the system has been destroyed ...". from that moment I did everything. Test point edl and Mi flash recognize as COM# but the flash error. I tried with the screen in fastboot also skips error. flash rom Mi a2 and mi6x. I try directly from the .bat but close immediately. xiaomi my unlock does not work. I do not know what else to do. I have installed all the usb drivers and nothing. I try with 3 pc's. really the one with the solution is a God.

Have you tried flashing the ROM manually (not with Miflash) from fastboot?

thats because the fastboot is not in the same folder as the .bat, and you hast to flash hex v288 for wayne in order to 9.3.14 to boot.

I used Havoc rom

In cmd:
Fastboot -w
Fastboot set_active b
And boot twrp

Thank you for this!!

Doesn't this leave you with a Chinese modem (limited LTE bands and roaming configs?) and critical partitions? Wouldn't an international or European tool be more suitable considering that Oxygen zips may not overwrite everything? Or is this just a temporary guide with what we have?

Temp? yes and no, I would say. Better than warranty R&D in days no phone for use.
As far as you can revive the phone from QDL9008 back to HOS/OOS, you now have a chance Again to switch over whatever ROM or OS you want later on.

Please help me, I failed pretty hard and bricked my phone.
I rooted my phone with stock recovery using a patched magisk boot image and all went fine.
Today, I deviced to temporarily boot into twrp to check it out, so I booted into fastboot and used "fastboot boot twrp.img"
and booted into system. I was confused and rebooted but now I was stuck in stock recovery. So I completely flashed TWRP
on boot_a and boot_b and into TWRP I rooted my device. But even now I am always bootlooping into TWRP and can't
get my phone to boot into system.
I tried using the unbrick tool but my device won't show up on my computer, even with the driver installed.
I'm screwed, can someone help?
Can I somehow reflash the stock recovery and revert back to my patched boot image?

Thanks for your replies! I was on OOS 9.5.5 and I tried flashing the twrp/magisk zips but that didn't work either. I also tried applying the stock boot.img to the active slot, but still got the recovery bootloop.
So as my last hope, I wiped all data in recovery mode, rebooted to fastboot and sideloaded the complete stock image from here https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
I reconfigured my phone from scratch, rooted with the patched boot image like before and everythings works now. Guess I will not bother with TWRP any time soon.

When I reboot into edl mode, it recognizes the "Qualcomm HS-USB QDLoader 9008", but then 10 seconds later, the phone automatically boots the the battery display, which disables edl. The same this happens whether I use the vol up+down and plug in, or `adb reboot edl`.
Edit: "How I learned to stop worrying and risk a brick"
Selecting the right COM and hitting start in MSMtool in that 10 second window kept it in edl mode for the duration of the flash.

thats good!
and how can i flash it?
My device is last week broken . is the rom flashable with fastboot? thx mike

How did you broken the device?

You can simply upload zip on device with adb command and flash by using stock recovery mode
adb push .....

I tried to flash my patched boot.img (via_magisk) with the MTKROOT V2.5.5 tool. -https://www.ayudaroot.com/root/vivo/como-rotear-los-telefonos-vivo-x60-pro-plus . The first problem was unlocking the bootloader. That did not make the tool. The tool failed .. I unlocked that manually in fastboot mode. After the bootloader was open, I tried the tool for the second time.
That was probably the serious mistake! The tool has transferred the patched boot img. So far everything was o. K. Then I booted to the Recovery Menu to clean the data and cache partition. (Factory Reset). Then restart system. Since then I have a bootloop and it was not possible to boot into recovery mode.
Then I flashed from the Indian Rom the boot and the recovery image.
Now the device booted again in Indian Recovery Mode (English). Then I tried to execute the recovery WLAN update. Unfortunately, the system has found no access points when searched.
!! F *** K !!
The next day I tried to flash the original CN-ROM with the QPST flashtool from https://www.needrom.com/download/vivo-x60-pro-plus/ ..
Here I had problems installing the Qualcomm driver for the EDL download mode or to boot the device in the EDL mode.
Without success!
Finally, I tried to flash all the items of the CN-ROM from Needrom via Fastboot. The Flash order of the items I had from the partition.xml file on the CN-ROM.
But I still have a bootloop ..
No access to the recovery WLAN Update-No networks are displayed ..
Do you have an idea for the EDL download mode?

My PC is over adb unautorized, after the Factory reset...

I managed to get this full rom from Recovery, there is a option to download the full last rom and burn. I use another phone with photo google translator to navegate in the menu.

I know this option with the update from the WLAN - but this option is no longer available to me - after the search for a network is completed, no further networks are displayed. He doesn't find any networks.

And the second problem was - I cannot import this Update.zip into the main directory because the PC is unauthorized.

It wasn't just the MTK tool that was wrong.
I think our mistake was you mixed recovery and boot of another Rom. I did that many years ago with Huawei but for me it was a hard brick. Better not mix!

yes i think thatat too. first step now- i try to put the phone in EDL download mode. Then I could try the Qualcomm Flash Tool -. .. But thank you anyway.

with which command did you unlocked the bootloader? I can't find a way.

@88user88 : i wish you the best.
Do you see a way to flash the indian ROM?

Question was not for me but:
I think i have a way that works. But for that I need the command to unlock the bootloader. Because none of the normal ones works.

hello i am a new user in vietnam, can you guide me in detail how to install . Thank you very much

I spent almost 5 hrs yesterday tried to flash from CN ROM, Origin OS to Global ROM, FunTouch OS. I used several methods including AFTool, QFIL, and QPST tool. None of them succeed.
AFTool - failed to flash because missing Fastboot batch file in the global firmware.
QFIL - failed to flash because, Qualcomm Driver 9808 not detected.
QPTS - failed to flash because, Qualcomm Driver 9808 not detected.
I like Origin OS but the reason I want to change to FunTouch OS is because Origin OS didn't come with Google Mobile Seevice package. In fact, 'Hey Google' also didn't worked out.

OK, if we manage to restore my device, I'll give you instructions on how you can unlock your bootloader. then at least I know that in an emergency you also have the option to restore your device.
otherwise it would be too unsafe for me ...
