Can anyone help me? Mi Max 3 can't be booted nor flashed anymore..

Hi I have a big problem with my Max 3.
I ulocked it and then I flashed it with the official Xiaomi Flash App and clicked the 'clean all and lock' button. Unfortunally I flashed a bad ROM.
Now I can only boot to recovery (This MIUI version can't be installed on this device) and Fastboot.
If I try to flash a ROM I see 'Erase not allowed in lock state'. I tried to unlock it with fastboot, I receive 'Token verify failed' I tried with Mi Unlock: My account is accepted and when I click Unlock
I have 'Current account is not bound to this device' But I can't bound it because i can't boot it!!
I would be very, very happy about a solution for this mess!!!
Thanks everyone who has i idea!

Use MiFlash tool, flash the fastboot version of latest global stable or beta rom on: https://forum.xda-developers.com/mi-max-3/how-to/rom-official-recovery-fastboot-roms-mi-t3827503

He already tried that. You can't use MiFlash with locked bootloader.
I am afraid you have bricked your phone. Unless you have an official Xiaomi servicecentre nearby.

Are you sure?

I had exactly the same. Locked my device when flashing (!!!?) then error while flashing, format the phone and everything was gone, locked bootloader.
After a search of 2 months I found out it was possible to repair the phone.
You have to open your phone, not very hard..follow this video https://youtu.be/dYlKG3EcpHg
Then contact the guys from S-Unlock https://s-unlock.com. I did it too, and they are thrustworthy.
You have to test point your device, https://youtu.be/IYWItgq2f9E until the Quallcom driver appears in your devicelist.
Then contact S-Unlock via chat. It can take up to 2 hours before the respond. The service cost 25 dollar for installing new Rom.
They log in to your computer via Teamviewer, they install MiFlash and Rom.
They have a special restore account. Without this account your Max will never work again, no need to try.
For 25 dollar my Max3 is working again.

Locked bootloader, stuck in recovery mode.

Hello guys.
I recently bought this phone and wanted to use netflix, but didn't allow me because it outdated and said it was not compatible with my phone. So I did a bit of research and found a post in "mi community" that said it was because phone had bootloader unlocked. The phone was new and I didn't change anything of it, but I found the bootloader was unlocked.
Installed fastboot and adb drivers, locked bootloader and got myself into a... Brick?
-I can still load into fastboot.
-If I turn on the phone, It tries to load android but loads Mi-Recovery 3.0 instead. Recovery also says "This MIUI version can't be installed on this device"
I'm so lost from this point, I need to know if there is a way to flash any rom, and which one do I need.
Thanks in advice

stuck on recovery
Most likely a chinese phone that came with global rom. If it came with global rom try flashing chinese rom and then unlocking bootloader and reflash global. Do not lock bootloader after flashing global.

Thanks for your answer, that is exactly what I've.
The problem is I tried to flash a Chinese from but it always denie it. Tried to flash the last global rom and allows me to do it with the same program.
Not sure where I can get the official chinese rom or how to bypass the xiaomi protection.
Thanks for helping! Hope I can somehow do it

Locked bootloader
Try searching for tools below which might help.
Saki / XiaomiADBFastbootTools
XiaomiADBFastbootTools-6.5.1-Win
I had hard bricked mine and had to take back off and use EDL to revive.

I don't find the way to reboot (via software) to EDL from fastboot, is still possible to access it by opening the phone?

If you can flash global ROM. I think you just need to unlock bootloader and then flash China ROM once you have unlocked bootloader.

It lets me flash de global one, but when I try to do the same with chinese rom, it says the version is lower, so I can't "downgrade".
It's weird because according to version number, the global one was a few versions lower

Solved the issue
The same issue , i was also encountered , After Flashing with "Xiaomi_Mi_Max_3_V10.2.1.0.PEDMIXM_20190226.0000.00_Global_9.0" Mi Max 3 with the MiFlash20191206 tool , by default the tool used "Clear data and Lock".
The tool saying "Flashing" and my phone got rebooted and went to MI Recovery 3.0 and also i got the message as
"This MIUI version can't be installed on this device".
I am not clueless how to proceed. So downloaded the Chinese version and again i tried to flash with above tool. Now tool said that "Can't Erase Locked" phone.
So Now i connected to Miflash_unlock with fastboot and connected to mi account and again i unlocked the phone.
Now my phone automatically booted to the Global version.
So i hope the issue is selecting the option as "Clear data and lock" . We need to select only "Clear data" in the flash tool.

Hi there,
I encountered the same issue. I tried to flash some CN Rom without enough research, without knowing that you can't just flash an Android 10 rom from 9 directly by recovery (even TWRP). So I ended up Fastboot or TWRP but never able to boot into system. Fortunately I didn't flash my Max3 by fastboot rushly, so my phone was still unlocked.
This is how I solved it:
1. Download an official CN ROM (the below I used is MIUI 11 with Android 9.9.x);
I can't post link here but search "miui通过线刷升级" - you shall see a miui.com link ending with shuaji-393.html. That's the page I download the Mi Max3 ROM from.
2. Use MiFlash to flash the official ROM with the flash option "clean all", NOT "clean All and lock";
3. The phone shall reboot into system, give it 5-10 minutes;
4. Flash the miui.eu ROM you like (DO make sure it is Android 9 tho) by recovery (tutorial given under every official xiaomi.eu ROM download).
Again it's easy to search
It took me less than an hour to do it (I don't have much experience with new XiaoMi phone). So don't worry about bricking your phone forever.
Hope it helps to destress

Hi guys. I need some help too because I'm not totally sure what I have to do here so if anyone can give me some tips I would appreciate it.
I just ordered the 128gb 6gb ram version of Mi Max 3 and it might come with the global rom and already unlocked. Should I use the Mi flash tool to install the file MIUI 11 V11.0.3.0.PEDCNXM android 9 fastboot file? then after that installs I should lock the bootloader and then unlock it again myself with my mi own account? I just want to make sure that this is the correct way to do it.
Also after it I unlock it should I flash the newest xiaomi.eu rom with android 10 or do i have to do something else first? Thank you

Help! Can't relock the bootloader

Guys, I have a problem. I need to relock the bootloader, I didn't had any problems before trying LineageOS and it's recovery... after testing the rom, I decided to go back to STOCK MIUI and relock the bootloader, but when mi flash finish installing and locking again the booloader, the system gets corrupted and I have to unlock the bootloader again (fortunately MI FLASH UNLOCK still lets me unlock the bootloader) ... This has never happened before, only after trying LOS recovery and Lineage OS official. My redmi 7 works with the bootloader unlocked but i can't get it locked again because "the phone system got destroyed".... i havent found nothing on the internet :/, have you any idea what this happens? cant get netflix working... Thanks in advice. Hope y'all are well

I just went through the same hell

Hi, glad to hear that i'm not the only one who had this problem, i had PixelExperience installed and wanted to go back to MIUI so i installed 11.0.5, this isn't the first time that i relocked the bootloader, so i knew what to do, but then the "Your system has been destroyed" message hit me, hopefully i tried and succesfully reunlocked the bootloader, and it just booted me in MIUI.
Soooo.... right now, my theory ( cause i've been able to relock the bootloader in the past ) is that somehow, MIUI 11.0.5 broke the relocking of the bootloader, so tomorrow ( cause right now im exhastued of what i just went through ) im going to try to install MIUI 10.3.4.0 and relock the bootloader.
If you want to give it a try and it works, reply to this comment, if tomorrow i try and it works i will let you know.
Hopefully it works tomorrow.
Sincerely, themselg

Hey Hi,
After using the Android 10 based rom you can't relock the bootloader of the phone using android 9 Fastboot ROM. wait for android 10 based official MIUI.

I just downgraded to MIUI 10.3.4.0 and can confirm that, that wasn't the problem, so yeah, we need to wait until the Android 10 based MIUI 11 rom comes to the device ( it just launched 3 days ago in China so i hope we don't have to wait that long ).
Cheers, themselg

i have the same issue of not able to get into recovery but able to go into fastboot while trying to boot normally just gets stuck at logo phone is able to charge. Showed to a local repair shop who says its a power ic issue searched web where someone mentioned about issue w flash memory (this was for some samsung phone not sure if it applies to mi). I have no clue does anyone know how i can eliminate some of my doubs step by step?
1. I think it may be my power/volume button strip but i dont know how can i test thee device without the strip (i have some schematics) .
2. Maybe Rom issue and since bootloader is locked and no usb debugging enabled nor i can unlock it using official tool since it requires me to go to developer settings and link my mi account i cant flash anything (though i came across some posts claiming you can bypass edl authorization using 2017-18 flash tools and anti5 test i dont have a clue as to what to do).
3. due to recent conflicts i cannot access mi india forums and nor can download proper official stock rom( since its my relatives phone i dont know what version it was on )
4. the phone was dropped previously which cracked the glass but was in working condition for more than 3-4 months atleast .Cant find any trace of water damage inside.
5. got some schematics from web by searching here and there but i dont know how to troubleshoot lol.
Any help would be appreciated , i cannot trust local technicians as there have been past incidences of missing parts from device after they keep for a day and return next day(skeptical if there are some parts missing or replaced w defective ones ).
Will update if i get it working.

Question Bootloop to fastboot logo and back in lock state

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot

I dont recall giving an error, so i dont think so

I'm not sure, but you may still be able to flash official ROMs.
But in "Configuration" make sure Erase is disabled

BAD NEWS... your Poco is bricked. You cannot flash ANYTHING using a PC when your bootloader is locked.
(I did same thing on a Mi11 5g last week and ended up selling it on eBay for spare & repairs
I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!

If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

That's what I'm thinking too ...
Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

tried unlocking it via the mi unlock tool (latest) but it says (in chinese) its locked by nr 123***456 by searching the phone - can't unlock

Is it not even possible to flash Official ROMs?
Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

I'm now in the procedure to sent it back under warranty. any idea if this is possible and what the cost would be if not under warranty?
If all fails i'll try the shorting by pins, should be interesting

I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
Let us know if you manage to get your phone booting up again

I once hardbricked (complete blackscreen, not even Fastboot reachable) a Poco F3.
I requested a replacement from Amazon and that worked.
I said a software update bricked it.
Of course having to do that is really bad, but I was scared of opening the back.
