Reflashing bootloader on Mi4C? - Xiaomi Mi 4C

Hi everyone,
I'm having this "locked bootloader" issue as probably hundreds other people do, since January update appeared. In my case the phone became unusable, stuck on MI logo, and also there is no recovery available.
I can only use fastboot.
I understand that some people managed to completely erase the eMMC and reflash the bootloader while the phone is connected to the computer in "Qualcomm HS-USB QDLoader 9008" or "QHS_USB Bulk" mode.
I can't figure out how to boot the phone in either of these modes! When connected through fastboot the MI4C is being recognized as "Marshall London Bootloader Interface". When I just turn it on and it's stuck on MI logo, it isn't recognized by device manager at all.
I'm on Windows 10 64 bit. Anyone has any idea what needs to be done to access these modes on Mi4C?
Many Thanks!

You need a working phone with USB debug enabled, then " adb reboot edl" from cmd... Sorry but if you are in a boot loop there is no knows way to access the Qualcomm mode...

There is no way for you to go into EDL mode. You need to apply for unlock permission from Xiaomi if you want to fix your mi4c yourself.
I applied for permission on Feb 1, and I got it today (Feb 18) despite the Chinese New Year holidays. I haven't even received my mi4c from China yet, and am not even a diamond member at miui.com, either. Good luck!!

Did you try flashing it with Miflash? I got bricked yesterday, so I reflashed system this way, but via Qualcomm HS-USB QDLoader. Also, my phone did not react to anything except bootloader mode (holding buttons for a long long time), no charging, no lights - nothing.

Me too
Me too. :crying:

Hi,
I have the same problem of the bootloader locked. Not let me do anything. It is blocked. I've tried to give instructions by ADB, but will not let me load any file since it claims to be the phone locked.
I have applied the code unlock via SMS to Xiaomi, but they are very slow. Yesterday I wrote and asked you to unlock it. They asked me 2 days more waiting, at least.
This is still horrible, a shame.
I read the post of a colleague who manages to unlock it but has to be the phone working. For those who stayed with my at startup, there is no solution.
Regards.

OPO doesn't switch to qualcomm hs-usb diagnostic 9006

my oneplus one is hard bricked. i tried several tools to recover my OPO, sadly nothing worked. The problem i've figured out is, that after flasing the 8974_msimage.mbn image my phone disconnects (sound from windows), reconnects again and the msm8974 download tool starts again. so i'm stuck like in this video:
The Qualcomm Flash image loader doesn't give me an error message (i can flash everything - i did so with Color.zip and with OPO Recovery Tools files), but still i get no vibration, no led light or anything else from the phone.
so what can i do for now? that's actually not my first android phone which is hard bricked (i helped a lot of friends of mine and i'm computer scientist as well....), so can anyone, please, help me!!!!
regards

Stuck at bootloop after update, can't access ADB.

Hi, I need your help here. I'm trying to fix my friends phone for her. What she told me is that it got stuck at the second boot screen after an update. She also said that it happened before and her father got it working. So my first thought was to clean flash stock firmware but I can't get ADB working. I've installed usb drivers and minimal ADB and fastboot but it doesn't recognize the phone in "adb devices" (I have no idea if USB debugging was on in dev options but I'm assuming it wasn't). I have no idea what to do now as I'm not that familiar with Xiaomi firmware.
Thanks in advance.
Edit: Xiaomiflash sees the device but not as COM.. but 72e728fb (?) and trying to flash it in this state ends with error:Flash xbl error

AFAIK , there's no such things as "automatically reboot after successfully flashed the device"
I was also in this condition but with different phone (it was Redmi 4 Prime (markw)), and all I did is just disconnect the battery form the circuit and then replug it, then I can boot to the system successfully
Hope it helps, but if it isn't then maybe something wrong

Pixel Bootloader Phone doesnt start

Hello all,
I have a Pixel1.
I was going to flash it and open the bootloader before. Everything prepared and plugged into the PC.
Via "fastboot reboot bootloader" I wanted to put the device into the bootloader to unlock it afterwards.
However, the device now does nothing.
Neither Power+Volume down does anything.
If I connect the device to the PC, the device is shown in the device manager as QUSB bulk.
Can anyone help me?

It's in emergency download mode (edl mode)
It may boot normally after battery dies.
If not you would need a blankflash for sailfish
I don't think there is one available for your device.
Edit: or mmcblk0.img for sailfish

Hard bricked Xiaomi 10 Lite in EDL mode

Hello,
First, some context:
After a factory reset of my Xiaomi Mi 10 Lite 5G (the phone is more than 2 years old, the warranty expired), the phone worked fine for a few days, but while playing a video game it suddenly crashed, then it showed up the following error: "Your device is corrupted. It cannot be trusted and will not boot."
Then the phone started displaying random white and black horizontal lines everywhere on the screen before shutting itself down again.
As of now, the screen stays completely dark, no sound, no vibration, no LED flashing, nothing shows on the screen whatever key combinaison I press.
Nothing happens when charging the phone either.
However, the device is recognized as "Qualcomm HS-USB QDLoader 9008" when plugged into my PC, so it is in EDL mode.
The phone has never been unlocked, nor flashed, and was (before this incident) running on the official MIUI 13 (Developer options had never been activated, nor ADB and it never entered into fastboot mode).
tl;dr; The device crashed without notice and put itself in EDL mode after displaying a worrying error message.
I tried draining the battery, no luck, nothing changed.
The phone is recognized by MiFlashPro (latest version: 7.3.706.21) but it shows a forseen error saying i need a authorized Mi account to flash it (but I don't want to pay 25$ a random guy on the Internet to flash it for me, knowing the device might be dead).
It is also recognized by QFIL, and I got my hands on a "patched Firehose" to bypass the authorized Mi account, but it always ends up showing the QSahara error (the error remains the same whatever firehose I select, patched or not, and whatever rawprogram*.xml too).
So, does anyone know how to flash a hard bricked Xiaomi in EDL mode using QFIL?
Anyway, I tried to be precise and concise, I hope someone has a working solution.
Thanks in advance for your answers!
PS: I tried to flash Monet EEA Global V13.0.4.0 (MIUI 13).
I have had the exact same problem happen to me with a Xiaomi Mi Note 10 Pro (tujana).it's just that I bought the device already bricked by the previous owner who flashed it with the ROM for the wrong device, namely the Redmi Note 10 Pro(sunny/mojito)I've since then succumbed to giving money to strangers online to flash it, but the flashing kept throwing an error(couple of guys tried it) and I couldn't flash it myself with QFIL as well, getting the same error messages as you. So I decided to dig a bit deeper and found out that the primary bootloader that is bar unflashable in those devices(please someone correct me if i'm wrong here) is different on the Xiaomi Mi Note 10 Pro that has version 2 primary BL and the Redmi Note 10 Pro has version 3. I do not know why and how the previous owner flashed the device to hardbrick it like that. I can't seem to figure it out. If anyone comes up with a solution I'm buying.
