I like downloading stuff. So I did. It's unfortunately, the same situation. Requires login. The ne2210 color OS tool also requires login and is only in Chinese. I messed around with different Msm tools but I only get an error that said the tool didn't match with the package.
Then I looked around more and found an interesting looking program from that site. Rom2box is advertised as authentication free repair tool. I looked into it. Don't know if it will be useful or not
To me, it looks like a manual MSM tool. Here's some pics. I tested it on my OnePlus 6T and it communicated with it fine.
This firmware flasher tab is under the Qualcomm section. Theres also a OPPO tab but it the same thing and probably useless.

Edit:
I found myself on one of those android hardware modding boxes seller forums and I found someone who uploaded a dumped OnePlus 10 EDL firehose. for his NE2210 COLOR OS model. I Don't know if this is useful in anyway as he too was looking for a unbrick method.
