This hasn't worked for me. It bricked my phone even further. The MTK Bypass bricked my phone and my pc and other pc can't detect my phone now :l

Anyone facing usb not responding/ recognised wait for battery to drain or just unplug battery by opening the phone from behind ( watch some YouTube videos ) and start again.
Next Time don't unplug during flashing

Thanks for replying, I did it before with other MTK devices, but this time, I can´t bypass this, I also had other message from SPFT, somthing like EXT_RAM_EXCEPTION, even I opened the back cover, so affordably can connect and disconnect the battery. Strange, but when it was detected like, MediaTek USB port, not like Preloader, it did start to flash.


Update: I got to flash it, I excluded cust, but still no screen is showing, device not turning on.

This is a last ditch effort to restore your phone to working order. This should only be used if your phone DOES NOT BOOT AT ALL or if you are unable to boot into FASTBOOT.
If you can boot into Fastboot mode then I would encourage you to flash using Mi Flash tool.

Tested! Howto Unbrick Redmi 9C (angelica) without using auth account

This blog has move and will not be update again.For new update please open ▶▶

First you need to extract the MTK bypass tool which is crucial as it will allow us to flash without requiring Auth file. NOTE: you need to disable antivirus or it will delete file.

Your PHONE NEEDS TO BE OFF! There is no need to unplug battery from the phone, I tested it myself and as long as the phone is OFF it'll still work. If your phone cannot power down due to bootloop, then you must remove backcover and unplug battery or just wait till battery runs out.


Once you have started the MTK bypass tool, choose MTK6765 from option that says auto and this is only for Redmi 9C. Now press on the bypass button a ad it will wait for you to connect your phone via USB. DO NOT CONNECT YOUR PHONE PRIOR TO THIS. Hold only the VOLUME UP button when connecting the USB cable to your phone and ensure the phone is OFF. ONCE you connect the phone, it will immediately respond and show a log saying its completed (SEE SCREENSHOT BELOW).


Once this step is completed leave your phone connected as you will soon start the flashing process. Open up SP FLASH TOOLS and run as admin. You will need to load the scatter file which is included in the Fastboot ROM under images folder. Once you have the scatter file loaded, SP tools will proceed to load all image files which will be used to flash phone so be patient.


Ensure that DOWNLOAD ONLY option is chosen as format and download option will format your IMEI also. Once all files have been loaded then just press the DOOWNLOAD button and wait to complete. Once done you can power ON the phone and it should boot.

It successfully flashes but when i reconnect the battery it does not boot.
And after the process when i connect it the computer it is recognised as a
"unknown USB device(Device descriptor request failed)

Now, more confused, then it didn´t work, but how did you flash through it?

The thing is that SPFT can´t get all the partitions flashed, for example, cust, and probably is needed more reserved partitions, and my device doesn´t boot, because of that, I guess the same for you.

TFT can flash all the partitions, even in this demo version, it could, but simply, is not working, and I doubt, it worked for someone.
