The file I downloaded doesn't seem to do anything. Is there a MSM download tool link or anything to download it? All the MSM versions I found so far either had the flash file missing or a patch wasn't correct. I'll even pay for the tool if needed

Will this work if phone says system destroyed?
The general consensus is to press and hold Power Off and Volume Up button and release when the screen goes off. Now your phone is switched off.

Now to enter the EDL mode you need to press and hold volume up and volume down buttons at the same time...and then connect the mobile to pc while still holding the buttons. Done.

MSM tool will detect your phone.

If you cannot enter EDL Mode for whatever reason - you might want to consider a replacement device.

It goes into EDL but then got a error 15s into it saying shara communication problem or something along those lines. It says system destroyed whenever it's turned on but I'm hoping it's fixable but have a board coming just in case.

Hi Everyone,

I keep on getting the Param preload failed error, tried updating all the drivers and using official OP cable. I am using Windows 11 Pro edition. Any ideas would be highly appreciated!

Hi,
one stupid Question. How can i install unsigned Drives on Win11? When i try to disable the sign check with bcdedit.exe /set nointegritychecks off i get an Error Message...
Firstly, turn off safeboot from BIOS if on. Then type the following command to enable test signing:
bcdedit.exe -set testsigning on
When done with the task, type the following command to disable test signing:
bcdedit.exe -set testsigning off
Just make sure you run CMD as an administrator. Turn on safeboot from BIOS if needed.

I had the same issue over and over again. What I did to fix it, was to let MSM running, don´t stop, just let them do, right click on the "Qualöcomm HS-USB QDLoader 9008 (COM4)" (in my case, it was COM3, but that shouldn´t matter) in the device manager and opened the settings, then open the "Port Settings" tab, click on advanced and change it to COM1. After this, I had to restart the phone and plug it into another USB port (I only got the one of my keyboard working), reentered the EDL-mode and MSM instant started the process...

Try to play around with the USB ports and when to restart the device and so on, if my solution doesn´t work. I´ve an OP 9 Pro EU, for clearification, if something should be different.

I'm not sure if this is the place to ask this but I do not have the "Ports" section in my Device Manager. I noticed this when my device failed to show up in the msmdownload tool. I am having this issue on Windows 11 and on Windows 10 running in a virtual machine. I have tried showing hidden devices and adding the port section using the "install legacy hardware" option but this issue persists. Has anyone encountered this issue?

The drivers posted have not worked for me, can someone please explain which drivers they installed and how? The drivers I have tried to install are not making the device show up in msm. As shown below, the digital signature cannot be verified even though I have disabled Windows from checking for this. Has anyone else encountered this error or does anyone know what might be causing it? Thank you.
