Phone stuck at a bootloop

Hello, firstly allow me to apologize for my English and long post.
I had a problem with TWRP not being able to perform any action due to not being able to mount data, after searching on the internet it was suggested to flash the recovery with OrangeFox, which I did but wish I hadn't.
Now my phone constantly reboots without showing anything on the screen, was it not for the vibration I would think that it was completely dead. It should be noted that it currently has no working ROM inside (hence why I was trying to flash another one with TWRP which was not working), before flashing OrangeFox when I opened it it went straight to the recovery, although it did show the Xiaomi brand while booting. Now I'm unable to perform any action, including the most important one, accessing the bootloader in order to flash another recovery. Is there anything that can be done by me? Is it dead for good? Do I have to send it to a technician?(I would rather try everything before that)

You may have to re-flash TWRP via ADB fastboot. Once you are done go straight to TWRP

I cannot access the bootloader to flash TWRP. I cannot also use ADB to reboot to bootloader because it doesn't recognize the device, it says "no devices connected" or something similar. When I was able to access the phone I had to change the usb mode to DIMI or something similar, I don't quite remember how it was called.

Same problem here
My redmi 6 is broken with a black screen and vibrates about every 10 seconds or so
sp flash tool might solve your problem; you can download the stockroom of your phone from the official website and try to flash it through SP Flash tool;
it's supposed to work but it didn't work for me; I get an error message ( BROM_CMD_FAIL) and MI flash tool asks for authorized account
I hope that you can fix your phone

Thanks for the information but that that was one of the first things I did; didn't work for me either. I gave it to Xiaomi to fix it, I expected to have to pay even though my phone is still in warranty but strangely they fixed it for free. I didn't tell them how it happened though, I just told them that it had stop working. I suppose that they didn't care to check whether I had done something on the device.

You still can just boot into your fastboot. You can't see it but if you manage to blindly boot into it, you'll see it in "fastboot devices"

Unfortunately, it didnt. I had to contact someone online to flash my phone with team viewer as he had an authorized mi account. It worked like charm
If it asks for an authorized account, then you have no other solution. That's what I learnt as I tried every possible solution I came across in the internet.

I contacted an Egyptian guy in facebook to fix the phone.
Not sure if it is allowed to post his profile link here as it will be counted as advertisement?
It cost me only $4.* (Around 5 dollars in PayPal). That was a year ago, I don't know if he still charges the same amount.

He is an Arab, I dunno if he speaks English. So I can try to contact him for you, but I will take no responsibility. I will link you together if you want. But, beyond this, I won't be involved.
I dealt with him, I paid him before I got my phone fixed, He gave me files to download and then he controller my laptop and used his account to flashy phone. So I only dealt with him once, and he was trustworthy at that time. But I can assure you nothing. It is up to you.

I'm in touch with a guy with and authorized EDL account for Xiaomi, who speaks Spanish and English, but he's not sure I'm plugging the phone in EDL mode, he insists that I must use the test points, I tried everything but I can't find them. So, was your phone before flashing just rebooting in a loop with a totally black screen and just small vibration after some seconds? That Arab guy was able to come alive your phone just with sp flashtools and an authorized account?
I guess my phone is in the same kind of brick that yours were, the only way to detect it in my laptop is keeping press the volume up button after plug and it appears in the devices manager just for a second unless I tried some operation with sp flashtools (error status_brom_cmd_fail (0xc0060005) by the way). Is this the same state your phone was?
Thank you so much for your help.

Which files he asked you to download ? Can tell us plz it will be helpful

Hi @Pradeep1998, as far as I know, the only way to unbrick a phone in that state is using sp flashtools, you won't be able to flash an image using miflash because the phone is unable to boot in recovery or fastboot modes.
I assumed the only thing I need to unbrick the phone is an authorized account to login when trying to flash.
I can tell you what steps I did to get to this point:
Install all necessary drivers on the computer to detect the phone. I presume you already have them.
Open device manager on Windows and plug the phone, in the USB computer port, with button volume + pressed. Wait a while and you should see a new interface show in just for 1-2 seconds. It appears every time the phone boot.
If you can see the device, it's time to try to flash:
Download and install MiFlash Pro. It includes a flashtool version integrated in some way with Xiaomi account, which is necessary to login and unlock the bootloader during flashing.
Download an image to flash for redmi 6 (cereus)
Download auth & DA files for spflash. I'm not sure if it's important use one or another, I use these that I got from some forum.
Open MiFlash Pro app and, in the top bar, you can see spflash, click there and spflashtool app will launch.
Load scatter file from cereus image and DA & auth files. If it throws a validation error loading the files, go to the options and uncheck one item to avoid validation (it has exactly the same name that the error)
Click Download, plug the phone with volume + pressed and when the app starts to flash a login Xiaomi miaccount windows will be shown; if you fill with your username data it will say, unauthorized account or something similar.
I hope this information is useful to you. Greets.

My phone had the same issue with yours ( black screen, vibrates every 4 or 5 seconds, and the laptop detects it only for a second when I plug it pressing power button as I remember, and sp flashtools gives me an error ( BROM_START FAIL SOMETHING) so it was exactly the same error. By the way, according to my knowledge there is no EDL mode for MTK devices ( redmi 6 comes with an MTK cpu).
The guy repaired it with mi flash tool ( mi flash comes with an sp flashtool that kept asking me for an authorized account).
So I think that your device can be fixed with an authorized mi account.

[HELP NEEDED] Bricked Tulip: EDL Mode only. Xiaomi won't help.

Hi,
I have somehow bricked my Xiaomi Redmi Note 6 Pro (Tulip) in a peculiar fashion.
It happened when a firmware flashing went downhill due to a faulty cable.
My device is now totally unresponsive. Pushing the power button does utterly nothing. There is no System, no Recovery, no Fastboot.
I managed to connect it in EDL mode (my PC sees it as "Qualcomm HS-USB QDLoader 9008" device).
With the correct drivers and after deactivating Windows Driver signature enforcing, I've been able to connect it with MiFlash Utility and receive the hello package.
UNFORTUNATELY, I cannot proceed to flash the new system image, since my Xiaomi Account does not have FLASHING PERMISSION.
I can't find any way to avoid this check. I mailed Xiaomi and they answered they can but won't help, since "it's my fault the phone is bricked".
Does anyone know how to flash in EDL mode without a flashing-enabled Xiaomi account?
Please, help. It's a fine phone, I'd hate to lose it when i'm just a mere security measure away from restoring it to perfect functionality!
Thanks for any help.

Funny I was just reading an article about this yesterday. There is only one way to fix this and that is with an authorized account. Sadly Xiaomi gave out a few account authorizations but won't do it anymore. Yet you may still be in luck if you open your wallet. The prices I saw were not very high $18-35USD. One of the guys here on XDA will do it remotely but I don't remember who. I found the article on mi-globe.com and will try and find it and link it.

Need help! No fastboot!

I was on Crdroid and wanted to get back into Miui since there was weekly miui 12 version now. Downloaded it and flashed it but it would not boot. I remembered on poco i had that i needed to flash latest miui andro 9 before flashing latest miui andro 10 for some reason so i got back into twrp and did it. After reboot it went into some sort of boot loot and i lost any recovery and fastboot. Cant get into edl for that matter also. Anyone has any suggestion?

Can you elaborate a bit more, when you try to boot into fastboot with the button combination, does it work?
Do you get any indications when trying to turn on your phone?

Button combination gives me blank screen and revovery gives MI logo and just that until it rebots and stays like that in some loop. I can get into test mode after opening it to try QFill flashing but i forgot about account authorisation thing. I do not have any type of service center in my country that wants to deal with this. Issue is probably due to anti rollback policy in 2s. So i need solution to flash somehow thru qualcomm port but aparently only wth that account that has authorisation.
Thats where i got till now. Spent a whole day also at 4pda trying to find solution but nothing there worked for me

Oh that's unfortunate! I think that in this case you will need to find someone with an authorized account that will flash it for you remotely. There have been some people around here offering that service for a small fee but it might be worth paying as that might be the only way to fix it.

Same thing happend to me, first time i tried using custom rom. i dont know what exactly happened. i think its have something common with anti-rollback feature. I sent the divice to OFFICIAL service center.... I told them "use mi flash tool and authorised account to flash fastboot rom in edl" These OFFICIAL trained technicians... ehm idiots... change whole mother board.... atleast they count it as warrasnty repair.... there is one guy on reddit who succesfull unbricked his device via "shady bussines" (there is also contact on reddit page)... some guys offer xiaomi unbrick services via teamviewer. you can give it a try: https://www.reddit.com/r/Xiaomi/comments/ftix9v/shady_services_unbrick_with_mi_authorised_account/ EDIT: its last reply reddit (hope its allowed to post links)
note: you can put yr device in edl mode by pressing powerbutton. im not sure if its pressing or holding. (yr phone need to by connected to pc, then mi flash detect the phone if all drivers are instaled, it should be shown in "windows device manager" as PORT named "qualcomm hs-usb qdloader 9008")
if you dont have authorised acc. this will happen https://imgur.com/a/oJVpKEl so you need someone with authorised account who will unbrick yr phone via teamviewer [Sorry for my bad english]
Ijust dont understand why xiaomi dont allow user flashing in edl mode... or just make harder to brick phone... i had oneplus and i never bricked it. bricking xiaomi is just super easy thank to their stupid anti-rollback and other b****its. i will never use custom rom on xiaomi again. i will dont buy xiaomi again

Did you try the MI Flash app? ...try to fastboot and check if mi flash works
Also try fastboot(combo-buttons only) and see if you can see the phone (cmd -> fastboot devices) ...if you see a device then you are good to go
If you have a fastboot miui rom you can use my guide: https://forum.xda-developers.com/xiaomi-mi-mix-2s/help/weird-behavior-boot-loop-random-t4086703
It's like using MI flash program but doing it manually - if mi flash gives you issues or else
P.S. CMD MUST be with administrator rights of course!

Hi Guys,
got a big problem here today. after installing on orangefox a miui11 stable rom suddenly flashlight went on and it stopped to install it... i was like WTF? so i have go to reboot to the recovery and my mix 2s DIED.
now
1) battery is drained
2) no fastboot (black screen on vol down + power key)
3) no recovery (black screen on vol up + power key)
4) bootloop on miui logo
any idea?

Question POCO X3 PRO device (brick)

Hello!
Sorry, I don't know vell ENG, so I use a translator.
Problem with Xiaomi Poco X3 Pro phone (Global Update 12.0.6.0.RJURUXM) + device unlocked
Unsuccessfully decided to flash the phone... I got the POCO X3 PRO and POCO X3 NFC phones mixed up a bit. I downloaded the firmware from the POCO X3 NFC and put it on the POCO X3 PRO via TWRP recovery. Then I tried to return everything as it was, but I couldn't. Accidentally via the TWRP menu formatted the System + partition Cache + Data and a few more sections, I don't really remember. At this stage, the phone was still functioning, turned on and rebooted in the recovery - TWRP menu. Then I tried to return the old recovery menu and connect Fastboot, but I couldn't. The phone turned into a brick. The phone does not turn on, does not work, the "POCO" logo does not appear, there is no way to go to recovery and Fastboot. The battery charge at that time was 46%...
HOWEVER, my computer sees the device as an emergency communication channel through the COM4 port - Qualcomm HS-USB QDLoader 9008 port
I'm already desperate and don't know what to do or what the instructions are... I don't want to open the phone and put it in EDL mode (if it helps at all)
I contacted a person with a service account, tried to restore the phone through the application "MiFlash_1212" by bypassing authorization and obtaining KEYS and access (I did not quite understand this point and how it works).
As a result, the firmware was able to run and the device began to be requested. But the following problem appeared, which I do not know how to solve, and that person stopped helping me (he has no time and simply does not want to, even though I paid him with money)
I read a lot of information on the form. Many tips and instructions did not help me.
What do I need to do? Who can I contact for help?
I wanted to get ROOT access (Magisc + YouTube Vanced + remove ads)
PS : But first I need to bring my phone back to life...

"I downloaded the firmware from the POCO X3 NFC and put it on the POCO X3 PRO via TWRP recovery."
-Why you put x3 nfc firm on x3 pro?

I guessed that you would ask about this moment.
It was my mistake and I thought they were the same.
And when the phone did not turn on properly, only THEN DID I REALIZE that I had downloaded the wrong files.
But what should I do?

As they say : "Hope dies last" =((

Chances are you will still be able to unbrick it by playing with fastboot and using normal miflash
For the firmware go and search on mifirm device code vayu or poco x3 pro download the fastboot rom it should be in .tgz format
Unzip it and then put it into miflash l, switch the phone to fastboot mode by pressing volume up + power button at the same time
Hopefully that would do the trick or you can just go and ask xiaomi repair center since this case should still be within warranty

Contact your nearest Customer Support Center. They will fix the problem

Hassle free, just go straight to customer service.
If you still want to work on this, fine.
Its a stretch but is fastboot function restored?
If yes, download the fastboot image (not recovery) of your phone region, skip the miflash application and run the flash_all+lock script. The .bat file.
Make sure you get the right version for your phone and your region.
From the logs, wouldn't really be surprised if you still have no fastboot access.
Looks like the guy scammed you.
Sure he indeed have the right edl authentication but he only did his job halfway and bailed as your phone are still loading in edl mode.

The phone did not turn on and fastboot and recovery do not enter any mode. The service can accept it, but it is clearly no longer under warranty and the price can be set very high.

This is likely because you might have format some important part as IMEI number. Like this guy said: https://forum.xda-developers.com/t/no-imei-and-no-wifi-plss-help.4276823/post-85014473
In this state, no matter what you do, you have to pay.

The most safe way is Xiaomi repair support center. High charge, but for sure a working phone.

Straight to service center you go then )
It should still be within warranty becuz they only refuse hardware error not software brick
Beside it shouldn't cost much tbh

i did this mistake with my brand new galaxy s6 when it came out but the only solution i had was going to repair shop and the dude used a hardware tool called octoplus and he flashed it and worked but i lost my original imei adress but it worked i did search for you i found the tool you need is ufi box google it contact them and see if you get one or find a repair shop by the way i repaired that s6 with 10bucks

unfortunately, your only option is service centre as they are the only one who can get access to phone via edl mode and flash what was formatted

Just to be sure, I asked customer support and they said the following... "By installing custom ROM, Recovery, and/or Rooting your phone, the warranty is not void. However if your phone bricks while installing a custom ROM, then the warranty is considered void". They adding insult to injury for you

Unable to flash in EDL mode. Error: object reference is not set to an instance of the object

Hello there!
My phone was bricked because I was flashing xiaomi.eu ROM in fastboot mode using cmd, and the flashing process was stopped midway.
I am able to enter into EDL mode only and only by using the test points, my phone is recognised as "Qualcomm HS-USB QDLoader 9008" as it should and also appears in MiFlash.
But when I try to flash a ROM (I tried global and Chinese) it gives me this error: "object reference is not set to an instance of the object".
I believe I have all the necessary drivers and my battery is probably long dead since the phone has been bricked for about a month now.
I read a bunch of articles describing similar problems but none of them gave a clear answer.

BlackTrade30 said:
Thank you for the quick reply!
I was guessing I needed an authorized account but MiFlash usually clearly indicated when you did. Something like "Authentication error". At least I have a solution!
Also, the thread you linked; the guy had symptoms that are exactly the same as I have. Unfortunately, he hasn't replied to me yet. According to him, he managed to get the phone unbricked using QFIL but didn't describe how. But thank you for bringing it to my attention!

Some old phones can be flashed without authorization but the k30 pro / poco f2 pro cannot.

Hello!
I have exactly the same problem as you (phone bricked after xiaomi.eu fastboot update) but i don't manage to enter in EDL mode even with testpoint... What did you used to do it?
Also, how much did you pay for the auth account perm?
Thanks.

Try flash it by UMT

Entering EDL mode should be possible using the test points.
Make sure your battery is disconnected.
Connect the USB to your phone but not to the PC.
Then short out the two pins.
I used tweezers to short them out.
While shorted plug in the USB the the PC. The PC then should detect the phone as a COM-PORT, you need the drivers if it says bulk device. It has to be USB 9008.
Now you need someone who can flash.
Mod edit: Paid services TG link removed.

EDL are Qcom's special access protocol. You should be able to flash via Qfil or Qpst suite, not Mi tool.

Respected sir,
Soft bricked locked bootloader Redmi 4 has same error in edl mode. Initially it was successfully flashed in edl with miflash few days ago to global fastboot rom Santoni_10.3NAMMIXM. It was working properly. Then It was showing latest update available 11.0.2NAMMIXM in setting, I downloaded and rebooted then after sometime It redirected 'mi recovery 3.0' instead of restarting the mobile automatically. Then i choosen to 'reboot to system' by volume buttons. Then it stucked on mi logo. Now i can't enter in "mi recovery 3.0". But by volume buttons i can fastboot, and In edl by shorting test points. Both are detecting device in miflash tool.
Fastboot mode flashing gives me "critical partition error"
EDL mode gives "object reference not set as an object" error in miflash tool this time.
Dear sir any suggestion or resolve for that.please help.
Thank you sir

Hello,
Voila, a perfectly detailed and unequivocal post as we would like to see more often.
Have you tried re-flashing 10.3NAMMIXM?
Send me the Miflash log (starting with Miflash "version") in private messages.
