has anyone been able to resolve the "Sahara Communicatin Failed" issue. I too have a LE2125 that does not seem to get pass this issue. I have updated the drivers, tried different ports, different cables, different computers and still the same problem.
 
I am currently on the 11.2.9.9 LE15BA ROm on my TMO 9 Pro. I want to revert back to stock TMO, with bootloader locked, like it came from the factory.

Reading through this, I would download the TMO version in the OP, and use MSM normally from there, right?

Am I missing anything, or this should work similar to how it did when i went from TMO to the current software?

I agree with only buying samsung and oneplus, but how I wish HTC would still make phones. By far the HTC M7, M8 and M9, are the best phones ever made, they were built to last, and where way ahead of it's time.
But I am intrigued on google working with Samsung to develop their own SOC, I think is name code white chapel, I want to see what google can accomplish with that, better battery life, better integration with custom camera... I don't know i have good feeling about it.
If you like HTC, then get a pixel 6 pro. Because that's who actually made them.

Guys, for those who can't restore using the method described here (sahar communication, device not match, etc.), the only method, which helped me is described here:
https://forum.xda-developers.com/t/...fix-msm-errors-sahara-param-info-etc.4306903/ - use it to upload the uncompressed/decrypted images from the packages you'd download according to this thread's description (you'll need a couple of tools like oppo_decrypt and payload_dumper to get the images you can actually flash). Also, for OnePlus 9 it may not work out of the box, you need to make sure you set the devicemodel (prjid).
I did not follow it exactly, because I knew what I was doing, it just helped me to find the tool. In any case, idea is to use this method to restore some or all of the partitions and THEN use MSM download tool, which WILL then work.
I hope it helps.

Thank you, craznazn

I was on Open Beta 2 with absolut No problems. Yesterday after clicking a link send by a friend by Whatsapp, my phone goes offline. No network, then come back. Then it started to restart by it self or shut down by it self.

I use the MSM tool to reset OnePlus 9 Pro. My phone was Locked & UnRooted.
I use the tool with Windows 11 x64 , Usb 3.0. My laptop does not have usb 2.0.
I was nervous about it, but it worked fine. When i got "QDLOADER 9008" in Device Manager > Portable Devices i was good to go.
Follow the steps in OP by the letter here & on OnePlus 8 Pro page linked in OP. The tool work fine on OnePlus 9 Pro.
Enjoy your phone.

I forgot to tell you..
First i try downgrade rom. 1 time the rom was flashed fine but the phone was still on A12. , 2 time, same. 3 time it worked. I was on A11, but the phone still restart or shut down by it self.
Then i use MSM.

Just a quick question as I had a request from a friend to convert LE2120 to UK/Global OS. Is it just straight forward process to flash EU/Global firmware with MSM? I have read through all the thread, so just want to confirm.

From what I understand, you actually have to run the India MSM, then install the global ROM

    Hello Brothers,
    Finally I did unbrick my LE2120 using LE2121 India variant MSM Tool from above link, here to give the clues:

    View attachment 5341829
    - Hold Vol-Up button + Power button more than 3 sec
    - Hold Vol-Down button, plug USB
    - Open MSM tool, make sure you get your COM PORT opened
    - Tick "Use Lite Firehose" checkbox
    - Click Start button, wait until finish, phone getting rebooted automatically...

    Regards,

    By using these tools, you accept full responsibility for your actions. Your warranty is void should you run any of these utilities without OnePlus support present. I am not responsible for bricks, fires, nuclear war, etc.

    If you modified any partition not touched by MSM, namely param and persist but there are others, you face a possibility of a hard brick. MSM will reset your "Enable OEM Unlocking" in dev settings and you might get a corrupt boot. Restore your backups before attempting. That said, If all you just tried to convert a ROM using OTA payload.bin, you should be fine.

    I've noticed that there is a bunch of loose threads with MSM tools posted, and some revisions still don't have it available. I decided to put them all in 1 place.

    If you don't know how to use these utilities, see https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/, as the instructions are the same.
