I tried this on my OnePlus 6T Tmobile - unfortunately the MSM tool connects, but will fail each time at 16 seconds with "Sahara Connection Failure". I've tried using USB 2.0 port, I've tried a known working cable, I've also tried holding down volume up + power.
I've also tried different versions including:
I have tried diagnosing the issue from this thread
, however, I'm wondering if there may be some other reason or possible alternative version.
Does anyone have any ideas on how to get past this?
For anyone reading this in the future, here is what happened:
1) For the initial MSM flash, I was using USB 3.0 port, which caused the issue, subsequent attempts, EDL loader was in some kind of bad state - Im not really sure how this is possible since its not writable, but I kept getting the same SAHARA comunnication errror...
2) to fix, I unplugged the phone - luckily, because it never got to start the flash, it was not soft bricked, then basically kept holding vol up and power until it rebooted into OS. Next I restarted MSM tool, made sure to plug into USB 2.0 port and rebooted into edl - and bam it finally worked.
