My phone was completely dead and now only the notification light blinks when charging it. Any ideas ?:(
I did all your steps and the download succeeded, no errors ........

My bad I let it charge for some minutes the led was stable so I turned it on only pressing the power button and it worked.
Thank you so much

Hi, I want to make a contribution, I had the same errors as you but I was able to solve it without doing a test point, it only turned on repeatedly because it was not loaded, once I loaded it I could turn it on in fastboot mode easily.
(I have to clarify that I have the bootloader unlocked)

"ginkgo_global_images_V11.0.12.0.PCOMIXM_20201119.0000.00_9.0_global_37804edbcb.tgz from https://bigota.d.miui.com/V11.0.11....XM_20201001.0000.00_9.0_global_389eff34c9.tgz"

These two files are not the same? Is that a mistake on your part; do I download the one from the link or go search for the one you mentioned we should downloads?
You must use the fastbootimage which is the same as it was on your phone when it was stock.
An older image won't work a newer could work.

I have no idea which one it was tbh. Since I had EXACT same problems as mentioned here and I totally lost all hope, I was just "f**k it", and did it. (do NOT follow my example).
The download finished first try, no issues whatsoever and my phone finally works!

Why I bricked it in the first place is because I tried to flash a custom ROM to try to see if that will fix my microphone issue. My mic doesn't work for around 10 seconds when any app accesses it (recording, video capture, call, etc) and then it starts working normally.

Unfortunately, it still doesn't work. At least now I can actually sell it for some value...

Lost boot and fastboot.
System Has Been Destroyed! Can not download the Qualcomm app from the link you provided but my son had a newer version.

When I follow those steps, I don't know where you get a patch file. It isn't mentioned in your description.

Wow, boy did this event set in motion a series of disasters.

Phone works. Stuck with STOCK ROM, can't root, everything is un decryptable with TWRP.
Lame.

Try the latest OrangeFox Recovery, I had decryption problems using twrp and A11. Otherwise if you can reach fastboot maybe try to reinstall the original stock rom again using official xiaomi flash tool, just make sure to use "clean all" NOT "clean and unlock"

Thank you very much for creating this post, I have managed to revive my redmi note 8 that I had left as a paperweight after trying a downgrade.
By the way, could someone give me a tip to place the back cover after the test point?

check the comments after the post, I linked the 2mm double sided tape I used and It's still working great. Either that or b7000 glue.

So I know that my phone was from batch 2020.11 and came with V11.0.11.0.PCOMIXM, which came out in 2020-10 according to https://xiaomifirmwareupdater.com/archive/miui/ginkgo/ . Following that logic I'd guess that your phone came with V11.0.8.0.PCOMIXM.

Thanks.
I have a rooted redmi note 8, I got it bricked when it tried to install the latest update (android 11). It rebooted for the update and instead of the original recovery, twrp launched and asked me about the lock pattern. It then stopped working. Doesn't even vibrate or anything, only black screen. I tried force reboot after waiting half an hour by pressing power/vol+/vol-, power alone, power/vol+ and power/vol-. Nothing worked. I tried while the phone is connected to the pc. I noticed that everytime I get notifications about usb disconnected/usb connected. The power led didn't even blink or the backlight.
I followed your tutorial. But I launched Miflash and installed the drivers first. Then I launched Qfil and clicked download. The phone rebooted as normal.
Now I'm going to retry updating to miui v12.0.2.0.RCOMIXM and root it afterwards.

    Hi all, after lots of trial & error, I would like to share how I managed to unbrick my Redmi Note 8
    original thread: https://forum.xda-developers.com/t/need-redmi-note-8-firehose-without-authentication.4031513/
    many thanks to dxD7 who provided valuable info on how this worked for him


    WARNING: this process requires you to enter EDL mode which means you have to separate backplate and short 2 pins on motherboard so USE AT YOUR OWN RISK! since its not quick&easy solution yet.. thanks Xiaomi! (n)

    Symptoms:

    • while pressing power button , the display backlight will turn on for approx a second and phone will vibrate and then turn off
    • while pressing power+volume- button, the phone will do the same as above but will show fastboot image for a second too
    • while phone is connected via cable its backlight will turn on for a second and thend turn off repeatedly..
    tested on ginko, batch 2020.11 - but should work on other (older phones as well) not tested on 8T-willow but might work - some mention about it is in original thread
    note that there is different kind of brick where after turning on the phone only the LED light blinks - it wasn't tested on that situtation but you can try it and pls let me know.



    What you will need

    clean windows without any previous ROM-flashing or android development drivers is recommended as it looks like windows is unable to fully uninstall previous drivers - they will reappear once device is connected


    STEPS:
    1. unpack ROM (for example to Desktop)
    2. unpack prog_emmc_firehose_Sm6125_ddr.zip and place prog_emmc_firehose_Sm6125_ddr.elf from .zip into your unpacked ROM folder: /ginkgo_global_images_V11.0.11.0.PCOMIXM_20201001.0000.00_9.0_global/images/prog_emmc_firehose_Sm6125_ddr.elf (overwrite the old one)
    3. run QFIL.exe and set it up similiarly like in this video (i know it's for 8T and but same principle is applicable here)
    4. leave QFIL.exe running, you will need it later
    5. now the tricky part. remove backlplate, connect phone using USB cable (prefferably stock cable that came with the phone and into USB2 slot) and short these 2 pins to get into EDL mode Screenshot_2.jpg
    6. you should hear windows sound of device plugged in. check in the device manager - it should report as unknown device QUSB_BULK_CID:XXXX_SN:XXXXXXXX
    7. now run xiaomi flash tool 20200314 and it will prompt to install drivers so click Install and check if your unknown device now reports as QUALCOMM HS-USB QDLoader 9008 (if install process happended too fast and you cannot see the driver (this happened to me) please remove anything from MiFlash20200314\log folder and try again)
    8. once the driver is installed, QFIL should show QUALCOMM HS-USB QDLoader 9008 instead of No Port Available
    9. click on Download Content to flash firmware
    10. now my 1st flash failed - I got Sahara Error, so I disconnected the cable, pressed all 3 buttons on phone for ~10seconds until screen blinked and phone vibrated
    11. I connected cable again, shorted these 2 pins to get into EDL mode, pressed Download content again and now it worked (took few minutes) and Download Succeed
    12. hold all 3 buttons for ~10seconds and phone should start up

    to my knowledge the error you will get the most in QFIL is Sahara Fail. according to the internet, this might be due to many reasons (bad cable, bad usb port, antivirus running, wrong firmware or firehose or wrong driver but in my case it was the wrong driver - internet is full of various qualcomm driver but I had succes only with the one included in xiaomi flash tool 20200314 ) for more troubleshooting please use for example https://www.nirsoft.net/utils/usbdeview.zip check if your driver's version is same as on the attached image (2.1.0.5)
    driver.jpg

    No reboot nor enabling unsigned drivers, running QFIL as administrator, disabling antivirus was needed in my case.

    Maybe some of these steps are unnecesarry, maybe this guide can be written more understandably - sorry for that - i wrote is asap so I won't forget anything I did during process. Please feel free to modify it or I will try to improve it in the future if I brick my phone again and have more knowledge about it..

    and I also need to figure out how to stick backplate to phone again so that it can be removed if needed while still preserving some kind of waterproof function..

    EDIT: bricked my phone 3 more times aftrer trying to install RR but was able to recover from all of them again

    thanks either that or I'm thinking about B7000 glue which looks like many people are using for sticking battery cover

    I live in canada and I found a 2mm double sided tape on amazon for like 10$ made for electronics. I think that's what I'll buy, and I can come back with an update if it's good or not. https://www.amazon.ca/dp/B00BXYWXY8/
