(20-02-2021, 04:48 PM)NyihuiGamer Hey, do you know how to backup your rom ? When i try to readback, spft says "please use official scatter" and then my phone can't be detected anymore. I had to go to service center to revive my phone again. Maybe it had something to do with python method ?

see https://www.hovatek.com/forum/thread-21970.html ; when using spft for readback, ensure to set UART connection

PLEASE DISREGARD. .. This Confirms that the method works with MEIZU M5 NOTE, MT6755. SEE the update below.
_____________________________
Testing the method for MT6755, but it wont proceed.
NOTE: **Successfully disabled the Protection using Python.

I suspect that the problem is within the Windows 7 COM Ports.
In SPFlash tool (Tried both v5.1824 and v5.2036) don't have the option to choose COM ports just like shown in the video guide.

Please see the screenshots:
https://ibb.co/k0MWjfB
https://ibb.co/Pgwyx6f

Do you have any way for us to assign in SP Flashtool to manually assign the Ports where the MTK USB port is assigned?

I saw the Video got COM10, but I do not have the option.
The Python is reading COM3, no matter which Flashtool version I use.
_______________________________

IT WORKED!
However, there's a little trick that has to be done. You should not use, UART. Use the USB option, and Download as normal. Although, this will still require the Auth File to be there.

***** Python is very necessary to disable to disable the protection.
- Go to SP flash tool, and set all your scatter files and the Authfile.
- Hit Download.
- Go back to command prompt Run "python main.py" in the designated folder. This is CRUCIAL. Has to run in the back ground as you plug the device to the PC.
- Flash will start with no issues if this steps are followed.

this works good if you have Auth file, though if you have auth file then you must have DA file as well and shouldn't really need to bypass protection, thanks for the info though (more alternatives)
maybe you needed to disable communication port for spft to pick up mtk port, at least on my pc i do not have any other ports under ports & lpt

Just held the button untill I've got this:

Now powershell just says:
[2021-03-06 17:56:44.325677] Found port = COM4
Nothing else pops up until I disconnect my phone.
whenever I plug in my redmi note 8 pro it doesn't disconnect (I don't have to hold vol+ button).
when I click downloand in SP tool it says "ERROR : STATUS_ERR (0xC0010001)

you might be holding the wrong key for getting a detection to mtk usb port, try vol down instead of vol up
also ensure to install device filter before proceeding to launch the py script

only use sp flash tool after brom bypass is successful
in spft, either use uart connection with 921600 speed OR use usb connection with high speed

for some reason nothing is happening when I hold vol down key. I've already installed device filter, when trying to do this again it just doesn't see my phone.
