Bootloop after changing the ROM - Xiaomi Poco X3 NFC Questions & Answers

hey guys! i've been changing lots for custom ROMs for a long time, and then decided to go for the Nitrogen OS and i don't know why but flashed the firmware. after that i got a bootloop. then i tried to flash a stock rom with miflash tool, but when the flashing was finished and the phone rebooted it restarted at 2.00% while installing the stock ROM files. i've tried nearly everything but still can't turn the phone on. thanks!

Try re flashing it again with the same rom or try again using different flash tool. It worked for me

[Q][GT-i9020a] How do I reflash back to factory?

Hi, new Android user here.
I was trying to root my Nexus S phone yesterday and I'm having problems. There is a lot of rooting guides out there and I used one from xda and also one from unlockr.com. Managed to root the phone ok (I think), but everytime I flash a custom ROM, the phone won't start at all, it just sits at the boot up screen and repeats itself.
So I'm thinking, I should just start over again. So I flash the stock ROM from xda back to 2.3.1. Everything seems ok, the phone starts up... but it's always stuck on airplane mode and the phone itself doesn't even show stuff like IMEI, mac address anymore.
So now I figure I've probably messed the phone up enough and need help lol. How do I go about reflashing the stock ROM and getting my Nexus back to out of the box condition (Stock ROM and no custom bootloader)?? Any guides or step by step instructions would be very helpful.
Thanks
Did you wipe before flashing roms?

Maybe flashing the KB2 modem would help that but the 9020a came stock with 2.3.3 and not 2.3.1 so that could be it...I'm not sure but that software wasn't meant at all for ours so it could be part of the problem. But if I was you I'd take a look at this thread wich has all the stock software for your phone. Make sure you wipe everything in clockework and then flash the stock rom. http://forum.xda-developers.com/showpost.php?p=13123996&postcount=39
dsixda uploaded the stock backup and the stock recovery, you can read more at that link, good luck hope it helps
You can download the full stock ROM from the link below:

Move the zip file to sdcard. Boot into recovery and flash the ROM. It should get you back to stock 2.3.4 ROM, all locked.

Can only boot stock rom (bootloader unlocked)

Hello! I was looking for some help with flashing ROMs. I have had my A700 flashed with other ROMs before like CM and IconiaN, but for some reason, now it will only boot the stock ROM. I had CM11 on it and decided to go back to IconiaN. Well, it wouldn't boot. To try and fix this, I went back to full stock ICS with a locked bootloader and stock recovery and started from scratch. I've tried about 4 or 5 times, unlcking the bootloader and flashing CWM, but every time I try to flash anything other than an official update.zip in CWM, it just hangs at the splash screen with the animated Acer logo. I did have TWRP for awhile too, but I had CWM originally and I have it now. Thanks!

Hey guys! Nevermind! I went back to stock again and tried another ROM first before I tried IconiaN, and it booted! So I guess it was just the .zip of IconiaN I have. Weird too because I re-downloaded the .zip. Anyway, I'm good now!

i9305 only flashable with Odin

Hi all,
So after re-installing stock 4.3 via odin, I realised why I hated stock and quickly tried to jump back to CM, however now I can't seem to install any other rom. At any time I can go back to stock via Odin, but I've tried 4 other roms and all of them get stuck in a bootloop. I've wiped / factory reset so many times it hurts, and have tried both CWM and TWRP, both seem to indicate that the install has worked without any problem, yet nothing ever loads.
Any ideas? I don't want to spend the rest of my life with the horror of stock rom!
Thanks.

If the 4 other roms you tried is of newer version of android, for example, lollipop, you may have to upgrade the bootloader first
How do I go about upgrading the bootloader? I installed cf-autoroot and then both twrp or cwm prior to installing the rom but still no joy. I also tried using Dr. Someones multitool prior to the cf-autoroot. Thanks for the help bud!
I just searched this off the Web, have not tried it myself. Since I don't have your device. So try it at your own risk

ROMs stuck in bootloop after working well for a while

Hello all. I found my Moto G ( XT1033) and decided to use it as a backup phone. Anyway, I flashed a CM12.1 ROM. Worked well for a while before switching off and getting stuck on a bootloop. Strange, I've already used it for some time. I thought maybe there were some problems with the ROM file. But now, I've tried it with Tesla, Blisspop, CM11, CM13. All have worked well for me in the past. Every ROM is facing the same problem.
Any help would be appreciated.
i face the same problem. its like everyday i have to do stock rom on my phone because it stuck on boatloader.
if all new clean flashed ROMs result in boot loops, you will have to reinstall stock ROM (with fastboot) to fix it. flashing stock ROM with custom recovery will not fix it though

Any idea what's causing it, though? I'm not able to flash a ROM into the device using the fastboot method. I've tried various builds, they all show the error after a few commands 'PARTITION SIZE IS SMALL' .
i'm not exactly sure whether you did it right. refer;
