Boot-loop Help - Xiaomi Mi A2 / 6X Questions & Answers

Hey, sorry to bother everyone with another bootloop thread by I just can't for the life of me work out if I'm doing something wrong, or my device is more of a dud than usual.
So got the phone yesterday, did some ota updates ended up in a bootloop.
Now at this point my bootloader wasn't unlockable as I hadn't enabled it in developer settings.
By some miracle it managed to boot itself back into the OS after an hour of fiddling and i decided to enable the option in developer settings.
Now I've unlocked the boot loader and got all the flashing related fastboot commands working i've
Flashed a stock image using the miflash tool, seems to succeed but then on reb but once it's done i'm still in a boot loop!
I've been able to boot into twrp a few times (though most of the time I can't and am still in a bootloop)
Tried flashing a custom rom, but I always seem to be in a boot loop after attempting that.
Throughout the last few hours i've also managed to hit the os a couple of times but it seems very easy to accidently put it back in a bootloop.
If anyone has advice of something to try, that would be great.
(was trying stock image version 10.0.9.0, going to try and go back to stock Oreo)

Sometimes it goes to a failed to boot screen, while other times it seems to loop endlessly.

Try some custom kernel, or patched boot img

I've found in 3 Mi A2 phones (mine, gf and family member) the bootloop is actually easy to overcome pretty quickly by waiting. I got the bootloop with all of them when they updated to two updates from what they came with no bootloader unlocked or flashing.
In each case I plugged the phone in, and left it rapidly turning on and off. Make sure to watch the phone, it will possibly come up with an error screen a couple of times so just press to continue trying to boot (also a glitched screen maybe that says fastboot with no options, press the volume control and the option to continue appears again). After a minute or two the phone will get to the normal charging screen, at that point the bootloop is fixed just hold power button until it starts.
Longest I had to wait was coming up to 2m, one time less than 30s.

Yeah, A2 have A/B partition and if update is faulty and the phone ends in bootloop, after a few failed boots, it will boot from other partition.

I think something along these lines is how i managed to get into the phone the first time and enable oem unlocking.
After a lot of playing around I was able to get the phone to boot by flashing the latest Oreo image (9.6.16)
After that tried going to a pie image again from fast-boot image (10.0.8) and once again ended up in a boot loop.
Lastly I flashed a fast-boot image of the latest ota (10.0.10) and managed to boot in.
So phone is at least all working now. Thanks for everyones help. Just hope the next ota doesn't bootloop the phone again.
@NotOverHere: When the phone finally does boot up, do you find it's stable and reboots are fine after that?

Bricked; cannot get into fastboot

So today I set about unlocking the bootloader and rooting my Moto X 2014 Pure Edition XT1095.
Unlocking the bootloader went just fine. Then I went to root it. I booted the pure2014sb.img but it didn't work. The phone would just hang on the Motorola logo. Then I read somebody later said that doesn't work on lollipop, so I booted the CF-Auto-Root-victara-victaratmo-xt1095.img instead. That showed me the rooting status page thing before it rebooted, and then rebooted again, but when it fired up after that it was still hanging on the Motorola logo.
Then I attempted this http://forum.xda-developers.com/showthread.php?p=56928477#post56928477
Now the phone will not even hang on the logo, it gets to the animated moto logo part and then turns off half way through. I cannot get back into fastboot state either. It just doesn't respond to power + vol down at all.
EDIT: Actually scratch the not being able to get into fastboot state thing. I just had to hold the buttons down for way longer than normal. I just kept holding them until it showed something. It ended up being like 15 seconds instead of 3-4 like usual.
Help!

Same happened to me early this morning when I was trying to install 5.0.2
You have to flash any firmware you want just avoid to flash the modem and there ate several post here in the general section
Just remember. Don't flash the modem unless is the same firmware you have or else you will lose signal.
Regards
Thanks for the input. I used the instructions in this thread to get my phone back to working condition:
http://forum.xda-developers.com/moto-x-2014/general/guide-update-xt1095-pure-edition-to-t2937074
I was unable to get it to pick up the 4.4.4 to 5.0 update zip in recovery mode, so I just used the regular OTA update to do it. After that I booted the CF-Auto-Root-victara-victaratmo-xt1095.img and it worked!

[Q] stuck on 'Erasing...', flashing doesn't help

Hi
I have an AT&T XT1058 with locked bootloader, on 4.4.4
I tried to rest it to factory, but it got stuck on 'Erasing...' (with the little droid) for more than an hour, so I reset it.
Since then it won't boot, only keep stuck on 'Erasing...'. I've tried reflashing it with ATT_XT1058_4.4.4-KXA21.12-L1.26_CFC_1FF both using RSD lite and manually using mfastboot, but no luck - the phone still boots to 'Erasing...' and sometimes after that to the recovery.
I didn't find anything in relevant threads. Does anyone have an idea?
Selecting 'Factory' in the bootloader seemed to fix it.
It is more comlicated than that
The phone does boot after selecting 'factory' in bootloader, but only once - turning the phone off and on again brings it back to its 'erasing...' state. Besides that the phone seems to not be able to charge the battery

Were you able to get this resolved? I have a xt1095 doing the same thing when I flash a stock recovery. Just shows the android guy and just stuck at erasing... When I flash TWRP it doesn't get stuck at the "erasing..." anymore but just boots straight into TWRP.
Sorry for the late response, I missed the notification on your message.
I wasn't able to fix it, returned it to motorola.

softbricked 6? stuck at boot animation

Was running stock 6.0.1 in unlocked mode, and applied the 7.0 OTA Tuesday AM. Phone booted fine, with the exception that the 6.0.1 boot animation displaying. Phone booted into 7.0, so whatever. worked great for 2 days, when i woke up yesterday screen wouldn't turn on, so hold the the power button and re-start. Phone got to boot animation and stayed there for an hour until i shut it off, never got to the pattern unlock screen. I've tried wiping it, factory resetting it, installing TWRP to wipe and install, nothing, still stuck at the boot animation, no matter how long i let it sit. I've tried flashing other roms, with the same results. I can get into bootloader and recovery without issue, and can flash without errors (that i'm aware of) but always have the same result. Any thoughts? Or am i going phone shopping today?

HELPPP!!! Stuck in Bootloop Nokia 8 TA-1004

I would like to ask some few solutions from expert people here. My phone was stuck in Boot loop for no apparent reason and cause. So, here's the chronology: I was playing Vainglory and it was still drafting heroes in ranked match. During that time, the phone just got freeze and unresponsive for several seconds. Then, it restarts and there we go. It starts boot loop cycle. I don't know what causes it.
How do I solve this? I need help, please. The Phone is Unlocked Bootloader and it is in root condition. As for the version, it was using 4.88B. I would require step by step detail in solving this boot loop before i decided to go to service center and have it fixed which is possible to remove Unlocked bootloader and root which I do not want that to happen.
Thank you so much in advance.
PS: After shutting it off for 30 min, I tried turning it back on. It does bring me to the home screen but then few seconds, it reboots again and causes boot loop. Nevertheless the case, once Powered by android logo came, I won't be able to bypass that.
Try to hold Volume up and Power while launching the phone - it will bring you into the recovery mode of android. From there you should wipe your phone data - sorry there's no viable solution for you, if it's a software bootloop then it should help you bring the phone to factory state and get rid of issues.

Sir, It doesn't show the recovery mode. It is like no recovery exist. It just shows Powered by android logo and then keeps restarting.
did you solve your issue? trying to reboot?
How did it happen?
and How did it solved? Did your phone start then?
I think from TWRP you choose to boot different slot.
So I think you have different Kernel-boot to another system-version

Pixel 4 XL won't boot anymore

Hello all,
I have been using my Pixel 4 XL for years, and all of a sudden it shut down, and now it keeps being stuck in a booting loop.
I get to Google's logo and the loading animation ... and then it turns black, and starts all over, in a loop.
I am able to access the bootloader and recovery mode.
I tried a complete wipe through recovery mode, didn't change anything.
I wanted to flash original images, but the bootloader is locked and I haven't found any way to unlock it without going through the phone settings (which doesn't boot anymore).
All fastboot flashing related commands fail stating my device is locked.
Would you have any suggestion ?
Anything I should try before considering my device is completely dead ?
Thanks in advance

Try sideloading an OTA image. You can do that with a locked bootloader.
Thanks Lughnasadh
I've tried multiple times, and the process fails randomly, at different percentages ...
The phone suddenly reboots and the laptop displays " adb: failed to read command: No error"
The weird thing is it doesn't reboot and can stay up for super long while on the bootloader.
With a locked bootloader the rescue OTA (full OTA image flashed via adb) is all you have. I would try a different data cable (A-to-C) first and then move to a different computer. Make sure the new PC is running the latest adb/fastboot binaries. This is why I unlock the bootloader on every Pixel in my family. Even though they will never root the phone, if the fit hits the shan you have many more options. BTW, I just traded in my son's P4XL and got $285 trade-in on a 6a. Net cost was less than $150. The deal just ended but will likely come back again. Same deal was offered earlier but included a pair of first-gen earbuds. Wish you luck on getting your old phone working. The P4XL is still my primary phone and is still working well.
