How are you getting into edl? are you using button combos? because when I was testing this it took a lot of time and effort and I got into it by chance in the way that is explained in the description. Even on my replacement OP8 I tried to get into edl with numerous button combos with ZERO luck.
Did you unlock your bootloader after running MSM?
No I did not

You might have a hardware failure. What was the reason you used the MSM tool in the first place?
i use msm tools because i try to downgrade form android 11 to 10., after it boots in crush dump mode so i use msm tools, everything is success , but the phone is just stock on android logo then off ( im not sure if its off but the screen is black) but i can go to fastboot mode and recovery mode ,

if its hardware failure , is it possible that i can still go to fastboot mode and recovery mode?

pls help.. ive done anything flash any version cause i think i brick my in2010 , using msm tool al success but when reboot still crush dump
Have you tried to boot into bootloader and do a full factory reset? I would try that and then reflash with MSM Tool.

But yours is Chinese version so I am not so sure that you want to be using this firmware. You would want the Chinese firmware.

Try using the other global msm software

If that doesn't work, try a fastboot rom, non stock

You can't make EDL packages by yourself, they're made and signed by OnePlus. Anyone being able to do so would mean this device is compromized from a security point of view.

so i have to wait then? :( i literally flash all firmware here nothing works ..

It may be time for you to process a repair or exchange. If you have the tmobile model, contact them.

If you have any other model (minus verizon), you'll have to go through oneplus. I hate to say this cause OnePlus is known for having the WORST customer service, and I can vouch personally that they do.
