Accidentally flashed to invalid file! Bricked phone! Help! - Redmi Note 8 Pro Questions & Answers

I accidentally did "fastboot flash preloader preloader.img" and now my phone won't boot, I can connect the cable and the phone led turns on and I get "sound of new device", however I can't do "fastboot devices or adb devices" nothing is found and after a bit the device disconnects from my PC.
What can I do to recover my phone? Please help I'm broke :crying::crying::crying::crying::crying:
Edit: the device is recognized as MediaTek USB Port, but SPFlashtool asks for permission, it has to be the authorized Xiaomi account that I need, I need this service please someone help me
Edit 2: Opened device, removed battery, tried to connect the test points, and no success SPFlashTool still requests authorization, and MiFlash does not recognize the phone at all (I think because it only works with fastboot?)

search in this RN8P thread some people got succeed after draining the battery

I've read everywhere about every RN8Pro brick. I removed my phone case, disconnected battery, waited 10 seconds, connected again, pressed volume powers + and -, did everything I could and SPFlash everytime asks for authorization and I can't get fastboot screen.

I'm begging for someone to give me service for authorization so I can unbrick my device, I'm begging with my life on it, I suffer of depression and you've no idea how hard this is for me, I use my phone to work and I'm dying here of the anxiety since yesterday because I'm broke and can't get a new phone, all I can afford is the service, please, contact me

Yes, someone with an authorized account can flash remotely your device, obviously this method require some money

I am contact a person he said you need ufi toll

The only way to solve your bootloop is a deep flashing, and for this you need an authorized account, search in YouTube or Google, XDA don't let people post numbers or contacts for business , is a rule..

I had same issue but i go to service centre and said that my phone was dead after updating (lie) after 1 hour they flashed my phone and no warrenty void.but keep in mind do not said about root if asking customer exicutive.

Hi - I'm sorry to 'hijack' this thread, but I have a quick question regarding bricking of devices. I've rooted my Note 8 Pro and it works nicely (I haven't restarted in a while). If I bricked it, would I know by now (as in, it would have been obvious when I was using fastboot and such)? Or upon restart, might there be an issue, if I use a new Magisk module or such? Thank you.

MiFlash Can not read from port com - whyred

Hi, can someone help? I was about to flash the official whyred Linedage OS for my Redmi Note 5. I did that with note 3 and note 4 before, so kind of knew what I was doing.. But was not aware of the antirollback thing.. So after i decided to flash the new miui 10 firs for the firmware..(wasn't the best idea I know) and you know the rest.. something went wrong and now I am stuck with dead phone.. no recovery, no fastboot, nothing.. I had unlocked bootloader officially a few weeks ago, got the device connected with the mi account (not sure about if the account is authorized or not).
I tried the test point method - dissembling the device from miui dot com
I have the right driver listed in device manager (Qualcom HS-USB QDLoader 9008)
I tried several roms listed here or miui dot com
I tired several versions of MiFlash
Every time I only get the message about not reading the com port (tried all USB ports on two PCs, reinstalled drivers .. everything) .. It starts flashing "read hello packet", then after 5 seconds stops with the mesage "can not read from port comXY"
In edb its just waiting for the device on any command (or not devices found)
Anyone can help please? I spent the whole day searching for solution and found nothing, or nothing helps
thx in advance

Yeah, posted my ID on the forum, got authorized, then used the "portable" miflash and it worked.. But on the other PC still got errors in miflash.. didn't even check for the authorization, so I suppose its PC related.. perhaps something with the drivers..

I faced the similar situation. I pasted the ID in the russian and english forum. I got no message for weeks, I thought of flashing again, Voila. Device flashed and turned ON. Your device is hard bricked as mine, it needs authentication from Mi to flash via EDL mode. All you need to do is download the MI flash tool portable, and paste your Mi ID in forums.
Unfortunately both the forum's date to paste the ID has been expired. But still you try to get help from someone else from the forum or the moderators.
I'll explain different errors I faced and the solution for it.
"not reading the com port" --- You get this error when you flash Global version of the ROM. Use the Developer version of it.
"It starts flashing "read hello packet"" --- You get this error because edl is turned off in your phone. To turn it back ON, just remove the USB cable from your phone and then press the power button for 10-15 seconds. Then connect your phone back again and try to flash.
"edb its just waiting for the device on any command" --- Actually this is not an error. Your phone is hard bricked. While in hard bricked mode adb won't work. ADB works only in fastboot mode.
Simple.. Disconnect and Reconnect with your PC Via Testpoint.. Thanks.
thank you very much

same problem with me . Have you solved it ?? let me know please
Hi Guys,
I have the same problem trying to flash MIUI 11 in mi A3 with MIUI 12. Anyone knows a solution for this?

my xiaomi redmi note 5 does not turn on, I think it's in fullbrick

you see, I made a bad installation of a rom and my phone no longer turns on (I can not enter bootloader or recovery mode) try to restore it by my flash. I recognize my flash device as COM but at the time of starting the flash it asks for an MI account (I log in with the account which is synchronized to the phone) but it always sends me error. I have been told that there is a solution through something called test point, but as far as I understand this is for the computer to recognize the phone. which I already do. Any advice or tutorial?
(sorry my english, I speak spanish.)

Error doesnt say much.. atleast write what does the error say... And yes, there is also qfil flashing method, which can revive basically dead device. But you have to open up device, take off back panel, and touch 2 metal thingies with a tweezers or something similar to enter qfil. I made a huge mistake few months ago, accidentally flashed firmware of another device onto RN5 and it just went through it, then it turned off, and was completely dead. No signs of life whatsoever, so i revived it using qfil method and flash stock firmware again. There are guides in this forum.

Hard-Bricked Redmi Note 8 Pro after MIUI 11 Update

Hello,
My phone got hard bricked yesterday after the MIUI 11 update. It was running fine before on lastest MIUI10 global ROM with persistent TWRP, root and magisk. Bootloader is unlocked.
The phone dont turn on anymore and just show a white notification led when plugged to a PC. No recovery or fastboot access
If i press volume up when i plug it to my pc, it show up as "Mediatek USB Port" and disappear after 5 seconds.
I tried to open the phone/ removing battery, shorting EDL test points, but nothing happens.
My only solution appears to be using Sp_flash_tool but seems like i need an authorized Mi account flash the stock ROM.
Do someone know where i can get acces to one of those account ?
Thanks for your replies guys !
Redmi Note 8 Pro Hard Bricked
I'm in the same situation.
please help me
Hello,
The same thing happened to me when I installed the Orange FOX recovery, it didn't go into Fastboot mode, so I had to press the 3 buttons and wait for it to turn off completely, open the ADB control console and then connect it to the PC via USB by pressing the volume + button.
The latter I did on several occasions (Turn it off completely and connect by USB). Until I recognized it, when I recognized them, I had to flash the SYSTEM, CUST, RECOVERY. One by one, in total it took almost 5 minutes.
After that the phone started normal, obviously without root, nor custom recovery.
I'm also in the same situation as all of you, the PC doesn't recognize me and I can't go into fastboot
Hey,
I tried everything I could (battery connected/unplugged), my phone seems to have a corrupted preloader and only start the boot rom. That's why it shows up as "Mediatek USB PORT", if the preloader was'nt corrupted, it should be named "MediaTek PreLoader USB VCOM port" or something similar.
The only way to recover it imo is to flash a healthy preloader using SPFlashTool low level flash mode and next flash a full rom when "MediaTek PreLoader USB VCOM port" appears in the device manager.
Unfortunately, xiaomi ask for a certified account for low level flashing. I found one but the guy ask for 40$ for just logging it into my pc with teamviewer.
I buyed a Samsung Note10+ in replacement and i'll just wait someone find a solution to sell my 10-day-used redmi if I can revive it one day.
I got hundreds $ of Xiaomi home automation products in my home, but that was my first phone from this brand. I think it will also be the last.
I'm sad to see that their security policy on the phones is so frustrating to the people who just want to have a full acces on their devices.
Authorise can be done with professional tools
Tools like umt, hydra tool, miracle xiaomi tool, does the authorization. And i think mtk cpu Auth will only be available in miracle xiaomi tool, be aware every Auth cost credit of 4 to 10 u will have but credit separate from the tool.. Hope this will help
MOD EDIT: quote removed help our devlopers lmao to get atleast one rom ??
They only need to unbrick sometimes.

I Faced The Same Problem Of Bricked Phone Of Redmi Note 8 Pro, I Was Unable To Enter Fastboot Mode, Recovery Mode & Even Can't Enter Into The System Because I Flash Wrong Boot.img File, Thereafter I Tried To Use SP Flash Tool But Failed Due To Xiaomi Authorised Account Issue. Then I Emailed Xiaomi For Getting My Account Authorised And They Emailed Back And Told Me That They Can't Authorise My Account..
Then I Decided To Visit Mi Service Centre As My Phone Was In Warranty, The Funniest Fact Is The Technicians Existed There Were Failed To Detect The Problem. I Told Them That My Phone Was Automatically Got Dead After Installing An Update Just For Making Them Unaware From The Real Fact.
I Told Them That There Is No Hardware Issue Only Need To Flash Original Firmware But They Are Freak And Didn't Listen To Me And Opened Up Every Part Of The Phone, Now They Told Me That The Phone Will Need 7 Days Of Repairing Take The Phone After 7 Days.
I Tried To Teach Them The Way By Which The Phone Could Be Repaired But They Only Listen To Me And Did Nothing, They Were Behaving Like A Beginner In Repairing Phone,
They Didn't Know That The Phone Can Also Be Reapired During Switched Off.
Now I Have To Wait For 7 Days, So Guys Flash Anything Carefully Otherwise You Will Face The Same Situation.
Thanks
Well I guess I won't unlock my device... To be honest I have no reason to do so. The phone is running great and I have adguard and removed all the apps I don't like using adb.

hi
does anyone find a solution for this?
please help
Well there is now a way to bypass the need for an authorized account, if you device is unbricked. Basically if you flash this before you brick your phone, it allows you to use sp flash to unbrick it without authorized account.

This is only for unbricked devices.... As I stated. If your device was already bricked it won't help you.
I also faced this problem... I used paid service to unbrick it... I must pay 35USD for the service.. but just wait.. If it works I will post here again. I bricked my phone when flashed anti brick on Android 10.. I forgot downgrade it to Android 9

Question hardk brick. no fastboot. no recovery.

I was trying xiaomi.eu on my global alioth. the current version for global is 12.5.4 but the one on xiaomi.eu is 12.5.8
using fastboot to update my phone, after a few minute phone went to the black screen forever. I can't even go to fastboot or recovery anymore.
although it's only showing a black screen, have you tried plugging phone in and running cmd 'fastboot devices' to see if phone shows at all?
also, have you tried holding power down for a good 20-30secs to reset/reboot device?
EDIT: read too quick... xiaomi.eu, no miflash used...

I bet you anything you and him had something go wrong with your PC. I restart my PC right before I flash anything and I close all application's and stop everything. While it flashes I don't touch my computer at all. I would assume that you guys might play on your PC while it's trying to flash thinking it's fine. Also you should use data cable or cable that came with it. Cheap cables are junk that's why they are cheap.
There is option to try EDL testpoint method when your phone is totally dead. It means you open your phone, connect testpoints and your phone would be visible for pc in device manager as qc9008 port.
Next step- you cant flash the rom by yourself, it requires authentication. There are "helpers" for that. I found one in Telegram and it took about 20usd and 20 minutes to boot the phone from dead brick (MI9T davinci).

If that's true that's awesome. How do you find these helpers? Do you have a link? I don't even know what EDL is I am wondering if it ever happens to me
Cant remember anymore where I found it, so many keywords were Google'd. Maybe it was some russian content. Im pretty sure I cant post telegram link here so if someone wants it, I would PM.
Hi thank you guys for the concern. Phone has been fixed. There is a remote service guy who helped me by using TeamViewer. If you guy out there who has the similar problem, you can go on YouTube and search "Xiaomi qc9008"

Working in IT for years, and all I can say if it would be true, we would have serious issues. It's not like windows 98 anymore, you can actually use your computer as a multitasking device. Like there aren't like 10000 processes without playing games. It's always easier to blame them, for doing "wrong" things while flashing. The only "wrong" thing you can do while flashing is pressing cancel or the reset button.

Question Hard brick my device installing windows

Well I did it, I killed my tablet installing windows. The brick started when I partitioned the device twice by mistake.
It is on a loop till the battery dies, can't access fastboot and can only get into recovery.
I've got an edl cable but still the pc does not recognises the device.
Anyone here has had this same issue?
Thanks

If your tab is going into recovery you should try Xiaomi Flash Tool i think they have a sideload or something.
Prior bricking the pad, your EDL cable worked? If so then your only option will be to open the device and search for EDL pads, or ask a Xiaomi authorized service to fix your PAD, this way you will not lose the waranty, if any.
