i guess i somewhat kinda bricked my nitrogen, please help out

So, somebody please help me. I had the chinese rom. fully updated.
I have no idea wich version it was but i belive most likely it was the last one since i got the telephone last week and updated it.
so, coming from mi max 1 and then mi max 2 i installed TWRP and booted into recovery
and tried to flash eu global rom but it came out as an error and i downloaded a few roms and tried but no sucess in flashing them and then suddenly the screen went black and i can hear it connect and it will show up in miflash but as for now i dont have the recovery files
and am downloading them at the moment.
I remember running into a similar issue on my mimax 2 or 1 and then i needed to flash it using adb and running the flash system commandoes.
But i forgot them and im sure some of you have done this so can anyone help me finding a recovery fastboot files and give me a either miflash supported file to use or adb files and then the commandoes to flash it all back?
it was something like
system flash
recovery flash
boot flash
etc
But i dont have the files for recovery fastboot
and the commandoes are lost for me.
It was like flashing in EDL mode i belive, if i can remember,
I really screwed up and since the telephone is so new its hard to find the files needed.
Thank you and please excuse my bad English.
The one getting me back ill paypal you a beer.

Which other roms did you try to install?
Latest china official roms have Anti-rollback enabled, so you have to be careful about what rom you trying to install otherwise your device will be hard bricked (if not bricked already).
If your device has bricked by anti-rollback, you need to flash in EDL mode, but EDL mode is blocked on Mi Max 3, so you need a Xiaomi EDL authorized account to flash with it.
Anyway, here is the link of the latest fastboot china stable rom http://bigota.d.miui.com/V9.6.12.0....EDCNFD_20180820.0000.00_8.1_cn_5e8d0ddf88.tgz
You can give it a try with MiFlash Tool.

My max 3 was bricked as well on Sat, no boot, no recovery, no fastboot.
You just need to download the fastboot of 8.9.20 china dev, install Qualcomm driver, then use Miflash to flash ur phone again in EDL mode. That's all.

Can you help me findig the link to dev rom?
I am really really lost..
Been at this things for 24 hours now, and i was working on my fiancees phone at the same time so after twrp my own i did his, and then of course we both have black screens now in download mode, and there is nothing i have done that
will get me back to fastboot or to twrp.
If i hold in power it just kinda restarts download mode i can hear on my computer as it make the Plug in plug out sound from the Usb.
I have already gotten a lot of ugly stare downs from my fiancee now and i really cannot afford buying two new phones and of course i shouldnt need to either as since they are in black screen download mode they can be flashed, but i need the file you sir are talking about and also if you can say wich kind of miflash you used and etc i would be very happy and im seriuous about that paypal buying you a beer and what not thing.
I am going on vacation in few days also so i desperately need the phones to work or its not gonna be any happy vacation and definetly not any "happy times" either. so please help out!!
I am also equipped with teamwiewer if necessary,
Also, i opened up my own telephone and tried shorting out the two connectors inside, "testpoint" but it didnt give any difference at all, and i am out of ideas.
And of course now it seems i have searched so long for the correct files i cant find anything any longer as im stuck.
so .- yeah. Please get me out of this mess.

this is the link of 8.9.20 (latest) dev fastboot: http://bigota.d.miui.com/8.9.20/nitrogen_images_8.9.20_20180920.0000.00_8.1_cn_7c2f993484.tgz
For MiFlash, just google "MiFlash 2018" and download the Portable version, that's enough.
For Qualcomm driver, google "QDLoader HS-USB Driver" and download/install it.
Make sure that you can enter the EDL mode, if you do it right, you will see the device as "Qualcomm 9008" (cannot remember exactly the name) and Miflash will recognize the COM port then you are good to move forward.

Xiaomi has locked the account of the other phone, you need a Mi Authorized Account, which is not easy to find and is paid of course. Don't flash Global Stable over your China Dev, unless you unlocked bootloader officially. But you have the option to flash Xiaomi.eu rom, if your bootloader is unlocked. If not - don't.

I do not really understand your current issue. A picture will be better? In case if you forgot to logout, it's ok, you just need to input the password of that account.
Anyway, you cannot flash Global stable 9.6.6 (MIUI 9) over the 8.9.20 (MIUI 10 - antirollback activated), it will brick again.

Both telephones are unlocked by the belonging miaccounts.
I have run the unlock tool on them both of course before doing the TWRP and then someplace something got messed up, not sure yet and made me in this mess.
What i have done in difference on my phone and the other is that i have opened up mine and short circuited lol almost all check points inside it and after the last link mentioned here with the rom it worked.
but im not sure if it was the testpoint trick at all as that really didnt give any information about anything changed or not.
What im trying to do here now is to somehow flash this edl phone left back to china dev without me opening it up and do the testpoint wich i have no idea helped me or not.
I can try the unlock tool again see if it recognize any phones.
all help appreciated.

Try flashing China 8.8.30 of the other phone, maybe it will skip asking for Mi authorized acc. I have red somewhere it worked .

OK-
So i can hereby confirm that TESTPOINT is working.
So if you have bricked your phone into edl mode download mode and there is NO WAY you can flash it using miflash or twrp or anything, you can open it up and unplug the battery, short cut the testpoints wich in my case was my fumbling around everyone with a wire and then
retry connecting the battery and reflash.
I also tried testpoint with battery connected. I have NO IDEA if that was the case or not.
But i managed to get back my phones, but of course i nicked one screen so im guessing im gonna need to sell this and rebuy a new one with global as to keep the housepeace intact.
So- i will try and rewrite this into something that can be sticked to the front. Including pictures.

So, if I understand correctly, without the testpoint method, MiFlash was asking you for an authorized xiaomi account but with the testpoint there is no need for authorization?

Well. Good question.
Seems like it doesn't need something else than unlock.
But verified account, its really not a big deal.
Just create a miaccount beforehand and wait the 500 or so hours to unlock.
If you screw up something just testpoint it.
But i was logged into the account on the telephone on miflash. But wasnt verified the laptop i used so i couldn't flash.
But with testpoint Wich was kinda nervewrecking i fixed them both. Again.
I will wait for global official rom before doing this again.

My mi Max 3 is unlocked and bricked. Computer detects it as 9008 and mi flash. When i flash 8.9.2 cn dev rom, it is stuck on dummy.img. It is stuck on dummy.img in other firmware versions as well. How can i fix it ?
Edit : solved by Flashing with QFIL.

Flashed mine to stock global rom.
I was so nervous as hell.
Downloaded the official global and didnt even have the nerves to twrp it.
Do i Flashed it using xiaomi mi flasher and it worked.
Dont feel like messing more with it now...

You didn't take a pic of the test points you shorted by any chance did you? I'm sure that will hep out some people.
Thanks

Is it even possible to unbrick a locked bootloader Redmi note 5 pro in 2020?

i have literally searched everywhere and tried the methods but to no avail. There are some old methods but they dont work anymore.
i cant access recovery but i can access fastboot but since my bootloader is locked, i guess thats no use.
1. Official flash wont work because not a authorised mi account (if someone have this, please for love of god help a brother out).
2.Tried the famous anti test https://www.youtube.com/watch?v=Pf_pPCGkldI&app=desktop but stuck at "ACK count dont match" and i guess others have this issue too. Do anyone know what this error mean in first place?
service center guys is waiting to rip off money with new motherboard but there must be someone somewhere who have good knowledge about and tweak something to make it work.
tl;dr: please provide a working unbricking method for RN5pro (working in 2020)

Hey bro as u can access fastboot mode, can u unlock ur bootloader via unlock tool?

No, you cant do that. You need to set in developler settings first but since the phone is stuck, you can't do it which means you can't unlock bootloader now using miunlock. if this was possible, we wont be whacking brains in edl n stuffs.
source: i have tried it already n didnt work.

No no, if you get ack error you just need to power cycle the phone (hold power button for 20-30 sec).
Really easy just need to be patient and retry.
Trust me I done it last week on my friends phone.
Just don't give up.. take a break and try it again. I done it in 3rd try. And use patched firehouse file on original MIUI fastboot rom.
Good luck!

I don't know if this help, I unlocked many Xiaomi devices and it usually takes a lot of wait time but I bought a RN5 Pro from second hand and when I tried to unlock it through Mi-Unlock Tool it did it instantly so it looks like Xiaomi don't care anymore for bothering on old devices, just in case you didn't try it previously.
Also it may help some screenshot as possible of your issue from the Mi Flash tool, I always used the Mi Flash tool Pro for unbrick purposes https://xiaomifirmware.com/downloads/miflashpro/ Have present that a device in this state is highly unresponsive so you have to try it a lot of times to get it working again changing always some things around.

Unlocked a Note 3 bricked like that back in the day using the EDL mode with MiFlash. Just a tip, don't know whether that'll work here.
Another tip: Don't buy any more Xiaomi devices.

Yeahh Xiaomi's edl authentication is bull****.
Locked edl flashing (which they thought was a security measure) but they bundle miui with full of crap and data miners.

Yes I tried everything even miflash pro and miflash 2018, miflash 2017 and flashing old rom both global or china mode with or without the new ssd660.elf files or patchprogram etc. I tried with connected battery and no battery in EDL mode and nothing is working just error of ACK COUNT COULDN'T MATCH cannot flash anything even with QFIL di qualcomm such a shame for Xiaomi! I think EMMC is corrupted then. Can't think of any other reason!
How did you solve the issue now in 2021?
What did you do?
Was the phone only able to go to fastboot and edl mode or also recovery? Cause mine only MI LOGO, fastboot and EDL mode with locked bootloader and EDL mode only via test point with open back cover!
Thanks

ACK COUNT COULDN'T MATCH this warning is linked to a synchronization attempt between programming Computer and interface controller the data transfer rate needs to be HIGHER than normal USB serial link transfer rate it seems.

(HELP!!!) Accidentaly Locked Boot Loader on wiped and bricked phone

Hello,
The Xiaomi 9 SE Global Unlocked of my girlfriend was restarting a lot (restart loop) and I tried to flash a ROM but I accidentaly flashed and locked the mobile on a "MIUI version that can´t be installed on this device" (grus_global_images_V12.0.2.0.QFBMIXM_20200910.0000.00_10.0_global)
The problem is the phone was wiped and I cant unlock the phone now. What to do? I can´t flash another ROM or unlock it and I just have access to Recovery Mode and Fastboot mode.
Please any help would be greatly appreciated.

It´s 4 am where I live and I´ll go to bed... But Will read here as soon as I´m awake. Thanks a lot in advance.

Let me continue my story... I still need help.
I contacted an authorized and he helped me to EDL a flashed version and I reinstalled the MIUI 12.0.2 Global stable on the phone.
But the phone is still TURNING OFF BY ITSELF (this was the reason because I tried flashing it on the first place). I don´t know the cause but it does not seems to be a faulty battery. I heard the phone has Anti RollBack protection. Is it right?
So I need help on how to procced. I would like to RollBack it to MIUI 11 where I didn´t had this problems...

Unfortunately you can NEVER go back once you flash a ROM on Xiaomi devices. However that doesn't prevent you from flashing custom ROMs.
Though you still need to be careful, because once flashed there is no going back.
I recommend testing the ROM on an emulator before flashing it. Here is how.
Also don't forget to check for your rollback protection index and the ROM's index before flashing.
Follow this post and scroll down to "How to find rollback index of images".

If Fastboot works, this means your phone is not bricked.
Just make sure your bootloader isn't relocked.
Then flash stock rom 12.5.1 using MiFlash, better than CMD command. You get to see errors in Miflash.
If it fails, then change USB port in your PC. ( USB ports on the back are recommended)
Good luck.

Dude we don't speak German you would have to use Google translate to tell us what it says in English. What did you do to your Poco f3 that bricked it? Do you have an unlocked bootloader? Because it looks to me like 20 threads a day are created for this phone by people who aren't actually into development but just want help, which is fine but it's not what xda is for.

So just a Black Screen? No Recovery or Fastboot?
You might have to flash a ROM via EDL Mode... The unfortunate thing though is that it will cost you money, unless you still have Warranty...
You said your PC briefly says that your phone got connected. In Device Manager, does it say "Qualcomm 9008" ? That would indicate that your phones' SOC detected that the Bootloader isn't working, and so, instead booted into the EDL Mode (Emergency DownLoad Mode), which is a read-only Mode inside the SOC itself.

This is why it is important to give as much detail as possible when asking a question.
If you had specified that the phone was less than 6 months old, I would have directed you to the warranty as suggested by CyanGalaxie.
Currently the guarantees are under contracted by Xiaomi and the returns are very bad (loss of the phone, broken screen, long delays, etc.).
In your case you got your phone back in 15 minutes, maybe it's better that way.

So I'm satisfied that it really worked within half an hour to "unlock" my cell phone again instead of sending it in etc.
I just tried to downgrade via sideload. that led to the EDL
All in all I'm glad that my cell phone is working again ... I'm just annoyed because I've been playing around with all sorts of cell phones for over 10 years and I couldn't figure it out myself

The best way to downgrade is to use Miflash or the bat file (Fastboot rom)included in the rom folder to avoid ARB.
Phones have since changed, notably with dynamic and A/B partitions.

If you were trying to downgrade/upgrade the FW due to requirement/recommendation by your Custom ROM, you can simply flash the FW inside TWRP/OrangeFox.

This method to have the right firmware for for example an aosp rom does not always work sometimes it is necessary to flash the full rom.
For a version change on a stock rom use fastboot roms which contain all the imgs.

Yeah, stupid anti-rollback thing. Threads like these make me wish someone already unlocks the EDL flashing. I heard developers need some source code or something for it, I'm not sure. But that needs to happen ASAP.
It's totally evil to keep EDL restricted.

For ARB okay but for EDL mode it's just a matter of security, you lose or your phone is stolen and just flash in edl mode and the phone is yours, no.
Then the guy will only be able to flash AOSP roms as he will be blocked by the Xiaomi account.
Note that this only concerns Qualcomm Socs,Mediatek are more less secure.

@NOSS8 We are modders and tinkerers here man. We were doing just fine before these restrictions. These restrictions have been added less for "security" and more to take control away from the end users anyway.

There are patched Firehose files (for QPST) on the internet (apparently circumvents the required Account authorisation). I can't provide a link, but you can google it.
But I'm not sure if those work, because I couldn't find one for Poco F3, and so I too had to pay 25$
It's very annoying that people buy into these pseudo-security lies we're getting fed so often (especially Apple Users). People don't realise this is not about protecting consumers, but simply for lé money. It has always been about the money.
Xiaomi locked the EDL Mode, because people kept buying their phones from China and import them to EU/USA, flash software with GMS and sell them here.
And locking EDL Mode causes more people to pay for Xiaomi Service Centres. xddd
I wish people would just have a healthy amount of criticism and not fanboy for any company, except for Valve. Valve is cool. Valve is love
