This is not something I can do anything for, contact OnePlus' CS at https://oneplus.com/support
thank you for the answer. I see no link for msm here but i managed to find another link from a telegram group. Yesterday my phone had recovery and fastboot mode broken, this morning i dont know how it booted to fastboot but it's not recognized in msm.
Can you send a link to the instruction?
I suggested you have a look at that post because of the failed DDR detection, not because of bootloop.
Install the driver
Thank you very much, you took a giant load off my chest, it worked perfectly with those drivers after some tinkering...Install the driver
Also click enum before selecting start on MSM tool
Seeing "Automatic detection of DDR failed" and "Waiting for device" in a red font. Anything I should do? I believe I have the correct drivers installed as it's listed as Qualcomm HS-USB QLOADER 9008 (COM3) in device manager.

Did you end up finding a solution for the "Automatic Detection of DDR failed" issue?

Sorry to spam, did you find a solution?
Nevermind! I think I fixed it but I'm not sure just yet.
For those who had problem with oneplus 8t released after March 2021,this new version of MSM Tools will fix it can goes back to HydogenOS stock.After that if you prefer oxygen OS just download a update zip and update from there.Finally, I just got the MSM Tool mentioned in that post and was able to get my phone back to H2OS!
Here is the link for those who don't have a OnePlus account or Baidu account:
Hope this helps someone out there.
I have also noticed few tips when using MSM Tools:
- If you get a "packed image not exist" error, make sure that your downloaded path does not contain multi-byte characters
- If downloading image to the phone fails in progress, you can try again by checking the "Use Firehose Lite" option (to use little slower and safer protocol)
