Phone stuck booting with no rom + not listed in Mi Flash tool or adb

Hi,
I'm fairly new to custom ROMs and the like. I just flashed LineageOS on my LeEco phone but am having trouble with doing the same on my Mi 5. I attempted to flash TWRP onto my phone using fastboot and unfortunately won't boot to it. I can now no longer find my phone listed in the Mi Flash tool or on adb. I believe USB debugging is turned off for some reason. I can access the phone's fastboot screen but can't doing anything past that.
Is there a way I can flash anything at all onto my phone as I believe I've royally buggered it up now.
Thanks..

Hey, so if you boot into Fastboot, your PC does not register anything? Nothing in MiFlash? And have you checked Windows Device Manager? It should register something (see atachment, but it's in my native language).

Mi A2 Bricked and I have no clue about how to resurect it.

Hello,
Recently, while updating PixelExperience ROM, I got my device bricked and while trying to resurrect the device through good ol' 'MiFlash' method rendered my screen like this 'press any key to shutdown' and strangest thing of all, when I power on my device, it doesn't show the unlocked logo anymore but when I run the code 'fastboot oem unlock', it shows that it's already unlocked. It would be greatly appreciated that if I get any solution.

You can try flashing the phone through EDL, that always does the trick for me. Just follow the guide to convert the phone but instead of converting just use the same ROM. (Jasmine system img for Jasmine and Wayne system img for Wayne.)

And to do that, I have to open up my phone, right?

Use a USB 2.0 port and latest platform-tools

You have to boot to bootloader in order to boot to EDL. You don't need any special cables like other xiaomi devices.
Typing "fastboot OEM EDL" in cmd should do it. The main reason I mentioned the guides is because of the QFIL program and modded fastboot commands that are in the convert.zip . You need that modded fastboot command to boot to EDL.

Bootloop + Twrp not installing properly

Hi everyone I need some serious help. I unlocked my bootloader just fine then booted into TWRP using the command
Code:
fastboot boot twrp-3.3.1-0-jasmine_sprout.img
after that used the ADB sideload button in TWRP. I used this command
Code:
adb sideload twrp-installer-3.3.1-0-jasmine_sprout.zip
which didn't work and then I eventually advanced wiped my device. The reason it didn't work ios because my xiaomi mi a2 isn't recognized as a ADB device, it only get recognized as a fastboot device. It is now stuck in a boot loop and can only boot into recovery. Any help would be appreciated.

Hello Mac,
Are you running the commands from the adb directory? Example, adb devices which typically would show your xiaomi mi a2 device.
Is the Android USB driver showing as adb in device manager?
I have the very same device, it is a little tricky since it has an a and b partition and you have to be precise when installing a custom ROM. Here's a how to that may be of help to you, it definitely helped me a lot.
Good luck!

What did you wipe? If anything except Dalvik Cache and/or Cache, then most probably you'll have to reflash stock ROM in fastboot.

If "Android Portable Device" drivers are installed correctly (and PC has USB2.0 slot and/or USB 3.x slot compatible with MiA2, which happens not so often), still ADB (if I am not mistaken) sees connected phone if it is
1) booted normally, USB Debugging is On, MTP is On, and ADB with this PC have been validated in phone (and still ADB has limited functionality depending on kernel), or
2) booted into TWRP
You can check ADB connection using "adb devices -l",
- if command shows nothing, then either drivers not installed or USB port is failing or nothing compatible booted in phone,
- if command shows unauthorized transport id, then you have not approved ADB in phone
If phone is in fastboot mode, then, with drivers installed and USB port being compatible, "fastboot devices" shhould show attached phone, and if it is fully unlocked, stock fastboot ROM can be reflashed

Redmi 4 (Santoni) bricked. Please help.

I unlocked my redmi 4 (Santoni) boot loader and flashed pixel experience ROM (https://mega.nz/#F!INZgnAZI!9fuWhfCuazOO5YPBjxGlmA). It was working fine for a few days (Small heating issue was there). Then one day while i was charging the phone the phone turned off and never turn back on. When i try to switch on the mi logo flashes for a split second and then turns off. I tried to get into recovery but couldn't.
I can get into fastboot mode. I tried flashing the phone using Mi flash tool and fastboot rom. But it shows an error "flash tz error". When i tried an old version of mi flash tool i get the "Unspecified error (0x80004005: FAILED (remote: Critical partition flashing is not allowed))
Please Help.....

Have you tried installing TWRP via fastboot?

I had the same exact problem, i put my phone on charge & when i came back to check it was switched off. It wouldn't turn on except the mi logo. I tried to flash through fastboot turns out my bootloader was re-locked for some reason. I had to re-unlock it then proceed on to fash fastboot miui rom. Check if your bootloader is locked or not.

This is a good idea! Probably u first try to install trwp in fastboot mode. If this doesn't work try to unlock bootloader again and then install trwp.
When all these Option doesn't work u still can open the phone and use edl fastboot mode to flash miui again.

One time fail in flashing = locked boot loader
Or for unlocking bootloader from official (easy) need live mobile not dead

Tried unlocking boot loader and was not successful because the phone was bricked. My only option was to use edl test point. Now i installed miui 11. (Aprart from some minor bugs which can be eliminated by reflashing some other roms) Thank you guys. Now my phone is successfully unbricked.

For somebody who is having the same issues,
My phone (Redmi 4_Santoni) was completely bricked. The only thing i can access was fastboot by pressing the volume down + Power button combination. But i could not install twrp or any other recovery because my boot loader was locked. I got it fixed completely with the help of you guys (Thanks again) and i want to share the procedure i went through.
Condition: Completely bricked with only fastboot access, Locked bootloader.
I tried this video (https://www.youtube.com/watch?v=j27x5iJSS40) but failed because i could not access recovery. So my only solution was to use edl test point flashing. I followed this guide https://forum.xda-developers.com/showpost.php?p=74818435&postcount=3. It was very easy to do. But in the device manager (Press Windows key + R and then type devmgmt.msc and press enter) instead of showing "Qualcomm HS-USB QDloader 9008", the device is shown as "Qualcomm HS-USB Diagnostics 900E". The problem was you have to plug in in USB cable while the test points is being connected with a pair of tweezers or a paperclip as shown in the link above.
Make sure you already downloaded the latest mi flash tool from here https://xiaomiflashtool.com/ and download fast boot rom from the official website. (Go to https://en.miui.com/ Click rom downloads. Click flashing guide. Download the fastboot rom from there for your device.) Now flash your device using mi flash tool and voila. your phone is unbricked.
Thank you guys..

May be your fastboot process failed...try again or go to recovery and clean all usure data

i tried,but now my phone is a pricey brick.
never again an mtk devices.

I have suffered this situation few days ago, I was using platform-tool to install MIUI 12.01 recovery rom using flash_all.bat but got bootloop everytime. Then I tried to flash the fastboot rom via Miflash tool and finally it booted up, it also re-locked bootloader after flashing, but the phone is live again!
I also tried to Wipe User Data in Recovery ([Volume up] + [Power]) before flashed the ROM with Miflash. Didn't know if it'd fixed the problem.

Have you try spflash tool yet?

fortunately i was able to recover the device using miflashtool then i sold it and i bought a redmi 9s
dont buy mtk devices guys,worst experience ever

You must know what you do on MTK than its ok!!!
