XIAOMI MI 8 - Impossible solution to bootloop - Android Q&A, Help & Troubleshooting

Hello guys, I really need your help!
I've just spent 5 hours trying to fix my Xiaomi Mi 8 bootloop.
Everything began this morning when I started a common update. After the reboot I got just an infinite bootloop on the white word "MI" that i get every time I turn the phone on.
I bought the phone from China with a Global rom already installed and the bootloader unlocked. I can access fastboot.
Here what I did today, until now:
-I decided to install a TWRP, only the 3.2.3.0 worked after many attemps with other versions.
-From twrp I flashed the last xiaomi eu stable. Result? Bootloop was still there.
-I flashed the last xiaomi eu weekly. Result? Bootloop there.
-I decided to go through Mi Flash.
-I installed the tool and downloaded the last Global Stable for fastboot installation.
-I flashed the global from Mi Flash. Result? Bootloop is here.
I don't really know what to do. Every time i did factory reset from twrp. I tried also to make the factory reset from fastboot command. I tried everything I could find online. No solution, same infinite bootloop.
Any suggestion? Thank you very much
Simone

Redmi note 3 kenzo not booting

Hey guys, I need some help urgently.I updated to the newest version of MIUI just now, and now my phone is stuck at boot. It just shows the MI logo and never goes past that.I can, however, access fastboot mode, but cannot power down the device. Can someone please tell me whether or not the phone is bricked, and how to recover from this situation?
Fastboot, reboot EDL and Mi FLash.

your phone is soft bricked, You need patched fastboot to reboot in EDL, a Fastboot ROM, and Mi Flash Tool. Goodluck.

Miui or rom from miui.eu ?
Last miui.eu rom let me with an empty /system the first time i flashed it, the second try work so i don't know why.
Try to see if you still have recovery access power + volume up
Unlocked or Locked bootloader?
locked bootloader.
It tells me Not enough space is available to process this command
No, I don't have access to the recovery.
I just switched to a newer version of MIflash.
Seems like it's working.
Guys it worked!!! Thank you, all of you for offering this newbie your help.

Left the phone (Redmi Note 3) on charging, came back and saw that it is stuck at mi l

It was completely fine before that. It has been 3 weeks since I rooted the phone and it has been working perfectly. There was a pending update though (couldn't install it because it was leading to TWRP recovery mode at boot for some reason).
The battery was low, I connected the charger (not PC) and now the phone is not booting up. Just stuck on the logo. I can go into recovery mode and fastboot but that's it. I have no idea how to proceed.
8.2.4.0 (MHOMIDL)
Android version 6.0.1
I followed this guide to root my phone - r/Xiaomi/wiki/advanced/root (on reddit.com) (I can't link the link)
I would appreciate any help
Try to flash miui with my flash or something custom with twrp, if you need to backup data, you can do it with twrp.
its soft bricked....use mi flash tool to fladh fadtboot rom

Redmi 3 Pro stuck/bootloop hopeless

R3 Pro (3GB/32GB, 2015817 version) came with some chinese/sellers custom ROM (and locked bootloader). It was heavy and bloated, so I decided to update it. Tried latest global stable (fastboot) ROM via miflash, flash was successful but that's was a lie - it stuck on mi logo...
Then I tried various other ROMs, global and developers, latest and older, some xiaomi.eu, manhit, etc. (for locked bootloader) and all I've got was either just a mi logo or mi logo with "powered by android" animation beneth. I left it for hours after flash and still nothing.
Then I found some ways to flash twrp, did that successfully, booted into it, wonder around in terminal and file manager, tried some recovery ROMs - but the result is the same - just logo or logo + animation.
I can get into fastboot (but it doesn't realy matters since bootloader is locked), download (EDL) mode, that Xiaomi menu (with Power and Vol+, with "shortcuts" to all the modes, hardware tests - btw. everything works there, etc.), twrp, charge battery (with some ROMs phone just gets warm and I know it's charging, there are no LED and/or animation, but in some everything works just like it should), but just can't boot into OS.
And I'm going nuts!
Here are some logs from the last ROM (i don't even know anymore which one is it) - pastebin.com/qaKVzxue and pastebin.com/dM3nEVj0
I'm not so experienced in looking at that but seems like every other thing in there, like cpu, i2c (touch/sensor), sound, battery, etc. is broken/faulty which is not true - everything was fine before update, and everything IS still fine according to inbuilt (xiaomi) hardware tests.
So somehow it seems that all the ido ROMs I tried are wrong for this device? Or am I missing something (quite possibly, I'm tired and pissed off)
Last night I did a backup of efs/nvram and then wiped internal memory/partitions, flashed latest global ROM, restored efs/nvram - phone stuck, but this time not on MI logo but freakin' penguin logo (like here en.miui.com/thread-377870-1-1.html). Same logo is for fastboot mode, no more bunny. Then flashed twrp and phone now shows mi logo with "powered by android" animation beneath, like before...
I don't know how this works with Xiaomi phones, but looks like it worked with some factory/seller special combination of ROM and bootloader. Then I did update and something stuck, maybe differences between ROM and bootloader, or some inside/hidden security mechanism that stops boot process? And because I can't find original firmware and/or bootloader is locked (maybe even updated?) it's now stuck...
Either that or some HW fault, but it would be insane that official ROM update with official tools and in factory download mode with full battery can cause such problem!
Can you go to twrp recovery?
Yes, like I said in the first post. I can do anything but boot android/MIUI. It's either because of locked bootloader or somehow official ROM installed officialy (via MiFlash in EDL mode) bricked phone, which is catastrophic bug i.e. epic design/implementation fail by Xiaomi.
Try this

Sorry to intrude, I have pretty much the same problem.
Phone is stuck in bootloop and I can only access fastboot mode and EDL mode (but in EDL the phone does not connect to pc) and when I try to flash a stock ROM (since I know it is a software issue due to an unfortunate update) it says "locked device". So I tried to unlock it via MiUnlock... but phone cannot be verified 'cause "account not bound to this device" and obviously I cannot change any options since I cannot use my phone.
Please, help
it was happened to me about 3 days ago when i play around with the twrp & rooting thingy... tried everything from youtube to various forum solutions... just one link really works when you only have fastboot options and your phone bootloader is still unlocked. just follow the steps in the OP... key things here is downloading the tool to read your phone as mentioned in the OP i.e [TOOL]Minimal ADB and Fastboot [1-6-17]
1) Download Tool -> https://forum.xda-developers.com/showthread.php?t=2317790
2) Follow all the steps in the OP -> http://en.miui.com/thread-277276-1-1.html
3) Enjoy your phone from back from the dead.. LOL!
4) Remember here, the key is NEVER GIVE UP and PATIENT!
NOTE : The Device will start, wait till completion , it can take up to 10 Minutes. -> for me around 15-20 minutes for I have flashed the current beta rom of MIUI8 7.6.8
cheers, guys!
blx-
I had a similar situation.
Officially unlocked boot loader. Flashed TWRP using fastboot. Only got the mi logo and a boot loop on start up.
Could not turn on. Could not boot into TWRP.
When the phone was boot looping I could still get into fastboot mode by holding power+volume down.
I booted from fastboot mode into TWRP by opening the command prompts and using
"fastboot boot twrp2.img"
That got the phone available from windows explorer. I was able to move a new ROM image to the SD card and install from TWRP.
Currently running lineage 14.1 -20190112.
I lost a bunch of **** but my phone seems to turn on for the moment.
Note, I still cannot boot into TWRP using the phone only. I can only boot in from fast boot as above.

EFS recovery

I think I have accidently erased EFS partition and I have no back up. I have seen a guide for restoring them for the redmi note 3 but nothing similar for the redmi note 4. Can anyone help me. I can install the official rom and an unofficial rom but the phone is in a constant bootloop and just restarts after 1 minute.
Just to add, I can't understand why it is bootlooping every minute. It means I can't do amything with it before it restarts. Adb recognizes the device and i have been able to get in long enough to see both imei's are gone. I get that I have wiped them but I don't understand why it is constantly bootlooping even after I put the official global rom put on and relocked it. After it went bad it would load recovery and fastboot but the screen was blank so I didn't realise at first until I noticed it was connected to Adb. Installing the global rom restored the recovery and fastboot screens but didn't help with the bootloop. If I could fix even just the boot loop it would be a start. Any help would be most appreciated even if it is just to tell me it is a lost cause.

XIAOMI 8 LITE only starts in FASTBOOT mode...why?

Hi,
mi XIAOMI 8 Lite today chrashed and when restarted was in FASTBOOT mode...
after several atempts finnally i could take him out from that mode,
