sofrbrick/bootloop - Xiaomi Mi Max 3 Questions & Answers

Hi all,
I am new to this forum, but have some experience with rooting and custom roms(oneplus one and samsung)
Now with the Mi Max 3, which was unlocked, i have flashed the recovery twrp-3.2.3-0-nitrogen.img, but I did not realize that
i had to reboot into this recovery from the fastboot mode.
so I endet up with a locked bootloader and bottloop and am not able to unlock the bootloader again.
I think my only solution is the test-point method and a EDL authorized account.
Some help would be greatly appreciated.
thanks
Henry

You don't have to boot into the bootloader from fastboot mode, you can press the power button and volume up button like on almost all other Android phones to boot into TWRP recovery. Sometimes it takes a few attempts to get right, but you should learn how to do it eventually.
Unfortunately it sounds like you had one of the dodgy re-sold Chinese models that had been re-flashed with Global firmware and it's locked your bootloader again on reboot.
Your only option is to use the official Miui Flash tool to boot into fastboot mode, flash the latest Global Developer ROM, and then sign in with your account and apply to unlock the bootloader again using the Miui unlock program. It may be instant but, they'll probably make you wait 720 hours, as the entire point of the program was to stop phones like yours being re-sold outside China.
At least you'll have a usable, non-bricked device though.

Thanks for your answer.
now I have opened the backcover (yes was much work ( I succeded without destroying something) and could apply the test point method to get into the lde mode.
Win10 shows it as qualcomxx at com 3
what is the best way now to awake it to life again? even without unlocking.

hi,
with the test point method I could flash the chinese rom, and the mi max 3 is awaken to life again!
The bootloader is still locked.
I have applied for unlocking, but have to wait some 15 days.
One tip: if the case is open, one can apply a little bit of silicon grease to the small pins on the side of the plastic frame
before closing it. Opening it again is much easier then.
One question: if I replace the recovery.img of the chinese rom with a TWRP image (renamed to recovery.img)
and flash that modified rom with the test point method, could this probaly work?
With a working TWRP one could install other roms without unlocking bootloader.
If yes, which TWRP would you apply?
Thanks

Flashing a recovery should not lock your bootloader, so I don't know how you did it. Note, that if you are using Xiaomi's firmware tool, you should not forget about unticking the box to lock the bootloader. But I would suggest to stay away from that tool and go command line instead with fastboot.
If you can access fastboot, I'd recommend to flash an official fastboot tgz ROM of your choice. Official ROM should boot even with an unlocked bootloader and you may start all over again more carefully.
So I think you might be able to avoid using EDL mode at this stage.

probally I forgot to untick that box. The bootloader is locked and I have to wait 319 hours.
I have got to love the test point EDL method which is simple and effective, and gave me control over the device again.
If I flash again the chinese fastboot rom (in which I have changed the original recovery.img into TWRP.img, named recovery.img) via the EDL
will that give me an installt TWRP (still with locked bootloader, but possible to install custom roms) or will i have a brick again?
thanks

Only you can answer that question by trying it out. Are you sure you have to wait for the unlocking again? Double check that! As I know you also need a priviliged xiaomi account to be able to resurrect a device in EDL mode.

Your device is corrupt. It can't be trusted and will not boot

Hi friends
Please give me suggestion or guide how to solve problem about handset booting after mistakenly handset OEM locked through fastboot
It enter to fastboot mode but not going to recovery mode or restart in system mode
Is there any solution
If yes then please help me
fastboot oem unlock ?
Actually ive unlocked OEM and install twrp recovery and installed freedom os
Then while checking OEM status ive enter command fastboot OEM lock
It ask me I've pressed yes after that the massage is came after restart as your device is corrupt it can't be trusted and will not boot
After that it enter to fastboot but not going to recovery mode or system
While type command in fastboot OEM unlock massege come failed
This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.
Can you unlock again?
@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.
When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

Not to be unrespectful, but you're wrong, it is absolutely possible to relock bootloader without problems.
IMHO, trouble happened because he had a custom rom onboard... and a locked bootloader does exactly its purpose... to not boot insecure firmware!

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.
I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days
DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

Did you by any chance re-lock the bootloader with a custom recovery and custom ROM flashed?
It's because of custom recovery.
Just flash stock recovery image before locking the bootloader.
This fixed for me.

You unlocked bootloader, flashed rom (custom) and relocked bootloader? Never lock your bootloader on a custom rom! Just enter fastboot again flash twrp (manual/force reboot recovery), copy internal storage to pc then wipe/format everything. Format data. Factory reset then flash latest official rom and reboot

are you tried this method before? the thread for Kenzo
It could work with devices with unlocked bootloader but in this case we couldn´t need it; devices with unlocked bootloader can be flashed using MiFlash Tool/fastboot and eventually TWRP.
It doesn´t work in devices with locked bootloader.
Technically script sends device to EDL but like the bootloader it´s locked it refuses to boot in EDL mode and restarts in the system finally.

Sorry, What do you mean?
If you ask if through EDL it's a cleanest method, no, there's no difference with fastboot method that you can use using MiFlash Tool or using fastboot commands to flash partitions

Do not worked
Hi.
This treatment does not work for redmi note 6 pro.
In my opinion Google should make EDL mandatory on any and every phone. If I remember correctly EDL makes Snapdragon phones unbrickable. Though Xiaomi has been locking it off and using proprietory code to put authorization locks on it.
I'm guessing because it's a major vulnerability (on Kenzo, I think EDL meant you could throw any file at the phone) but the easy fix there is simply enforcing a hardcoded checksum for any incoming recovery file.
But really Google needs to make sure phones can be easily recovered by consumers from even the dodgiest bootloader flashes, botched flash memory situations, modem edits, mismatched firmware somehow flashing to the wrong phone and whatever other ways a phone can be messed up.

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

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

OEM Locked, and Device is corrupt. Unfixable?

So, long story short I recently decided to try and root my oneplus7t I unfortunately made some mistakes and somehow corrupted some files. I read elsewhere in the forum that I could download the stock rom which I did and then use flash-all and that would allow me to go back to the factory settings so I could lock the oem and just go back to normal because I was tired of the headache. Unfortunately, after using flash-all I locked the oem thinking everything should be stock and it would work properly. But it says device is corrupt and trying to unlock the oem says oem unlocking is disabled.
So did I just completely brick my phone? I don't know of anyway to fix it at this point :/.

Can you still boot into bootloader via the hardware keys, whatever that combo is on the 7t?
Boot to bootloader or recovery and factory reset it or so.

I can get to the bootloader but it's Device State -locked and when I tell it to boot into recovery it says the device is corrupt. When I use fastboot to oem unlock it says I cannot, and I can't flash when oem is locked either.

Try

Let me know if that works or not we will move on. Probably won't work since it's bootloader locked
You may have to contact OP and while you're at it, get the MSM tool for us all :good:
It says erase is not allowed in locked state . I think this is probably all she wrote for this one. I think I'm just going to send it back tbh, the whole reason I was trying to root it was because it didn't work with Sprint like they said it would. and I was wondering if I could find a way too make it work with custom software.

I unfortunately no longer have Twrp installed as I did a flash-all with a stock rom already . If I try and flash recovery it says "flashing is not alllowed in lock state".

How did you flash twrp with it oem locked??That doesnt make sense
I had twrp on it when the oem was unlocked, I was trying to reset the device to stock, so I did a flash-all and then oem locked it. But for some reason the repair was unsuccessful, and now it says my device is corrupted and I forgot to turn on oem unlocking in the settings on my phone after the flash-all before I did the oem-lock.

Looks like you will need the MSM tool to fix this issue. You'll have to contact OP support and they will remote in your PC, load their software and flash it 100pct back to stock.
Also, disconnect them before they can delete the MSM tool so we can have it here in the community

Press volume up/down and power, reboot to fastboot. Unlock bootloader again. Install update from settings, reboot and install it again. (local install)
Factory reset in setting, reboot fastboot, lock bootloader. Reboot and untick unlock bootloader in developer settings.
Don't know if it's too late but I believe there's a working MSM tool now

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

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.

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

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 also tried to simulate a local OTA by copying update.zip to internal storage using ADB push command and booting into recovery mode to flash ... But it doesn't work 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

[Solved] Stuck in fastboot with locked bootloader
HI there! After multiple problems with the custom ROMs I tested, I finally decided to go back to the stock ROM by downloading it from the official thread. I extracted the .tgz archive, run the "flash_all.bat" program, which failed by saying it...

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.
