Strange, none of the things you said work should've worked, and none of the things you said didn't work should have worked.

Let's clarify a few things:

You have LE2125 Global.

You tried to MSM with the tool lemonadep_22_O.05_210324.

You ran into errors (what errors?).

You then tried lemonadep_22_I.07_210412 and it worked.

You are running 11.2.4.4 DA

You tried to switch to Global via Oxygen Updater (did you select full or incremental?)

The switch/local upgrade succeeded, but it still says 11.2.4.4 DA

Also, have you tried to local upgrade with https://www.oneplus.com/global/support/softwareupgrade/details?code=PM1617074857015
[OnePlus 9 Pro] nightpanda2810:
LOL, of course I would tread new ground.

Yes. Says so on the box and in about phone under model.

Correct.

Initially, a "sahara" message. After checking "use lite firehose", different message, don't remember exactly (should have screenshotted, but it was late lol) but something along the lines of a device mismatch.

Correct.

After initial install yes.

I used Oxygen Updater to download the ZIP, used TWRP to install. Full. Was successful.

Build number currently says 11.2.7.7.LE15DA. I did not think to check what it was after flashing the Global ZIP, went straight to system update (not Oxygen Updater). I did both slots to keep things consistent.

Yes, but through TWRP.

Edit: Everything appears to be working as-is, with root. Still concerned there's a hidden issue.
[OnePlus 9 Pro] craznazn:
Sounds like Oxygen updater downloaded and you installed the Indian variant. Don't use TWRP to install OTAs. Use Settings -> System Update -> Top right gear icon -> Local Upgrade.

Use https://oxygenos.oneplus.net/OnePlu..._downgrade_for_Android12_27464c839e16428b.zip as a downgrade. You'll lose data but should be back on NA. Again, don't use TWRP.
[OnePlus 9 Pro] nightpanda2810:
Thanks, I'll give it a shot!

TWRP is what got both of my slots in a functional state, but no problem doing it this way. Will report back later.
[OnePlus 9 Pro] nightpanda2810:
Success! I'm now on the correct version. However, slot A does not boot. Loops back to slot B when I attempt.

Would like to get slot A functioning again, but unsure how to go about it.
[OnePlus 9 Pro] craznazn:
While in slot B, use local upgrade again.
[OnePlus 9 Pro] nightpanda2810:
Thought so, but didn't want to wipe again right now, lol. Thanks for all the assistance!
[OnePlus 9 Pro] dkcats3:
Firehose lite saved me this time. Thanks, I never would have figured that out lol

@Timmmmaaahh! can this thread be stickied? It's definitely going to be one of the most important for people who get into trouble.

Not sure if it's elaborate enough to meet sticky standards but will surely look into it.

Edit: Nevermind. This thread was reviewed on May 20th for sticking but had been denied. It's a if-we-stick-this-one-we-need-to-stick-a-bunch-of-other-ones-which-would-defeat-the-purpose-of-stickies situation. Sorry. 🤷‍♂️

[OnePlus 9 Pro] thirtythr33:
if I use msm tool (global/AA) do I need to do anything special before I start the process, or can I just follow the directions and give it a shot? (my bootloader is unlocked etc)
[OnePlus 9 Pro] ctonylee1965:
Anyone know how to fix the device not match image error in MSM?
[OnePlus 9 Pro] radialblur:
Just downloaded the EU version and BitDefender doesn't like it...

"The file C:\Android\MSM\lemonadep_22_E.05_210324.zip.part=>lemonadep_22_E.05_210324/MsmDownloadTool V4.0.exe is infected with Trojan.GenericKD.45674771 and was moved to quarantine. It is recommended that you run a System Scan to make sure your system is clean."

Hi guys,

I think, some people here have this problem.

I can't MSM flash EU LE2123 OnePlus 9 Pro. It's totally bricked (not even Fastboot working), though Windows sees it in MSM mode. MSM tool reports either "Sahara Communication..." or "Device not match image" in Lite mode. LE2123 is written on the back and I actually tried all images (Global, India, EU, T-Mobile) to no avail. Any suggestions?

You are a lifesaver!

Thank you so much!

Hello Friends, I want to return to Stock from Custom ROM.

My OPO9 pro was LE2120 in system details. When I flashed a custom ROM and now the system displays the device as LE2123. My bootloader is unlocked.

How can I go back to stock? If I use MSM, should everything be fine? Which MSM to use? LE2120 or 2123??
[OnePlus 9 Pro] RicardoDimm:
What was the solution?
[OnePlus 9 Pro] RicardoDimm:
Got my 9 Pro hard bricked, and when using MSM Tool Sahara Communication failed. Any tips?

MSM download tool gives Sahara Communication error

When I check ''Use Lite Firehose'' I get errom Param preload - Device not match image

If we are using MSM to convert T-Mo (LE2127) to EU version, do we need to first backup the persist, modemst1/st2 files first?

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?
[OnePlus 9 Pro] Libra420T:
yup just use tmo msm 😊 👍

[OnePlus 9 Pro] amingin:
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://xdaforums.com/t/advanced-untested-possible-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.

hello guys I'm trying to revert back to TMobile via msm tool lemonadept and get error message mismatch eu. but when I use msm eu it works. how can I revert back to TMobile? thx in advance
[OnePlus 9 Pro] null0seven:
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.

LE

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.
[OnePlus 9 Pro] Wyshniukas:
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.
[OnePlus 9 Pro] craznazn:
From what I understand, you actually have to run the India MSM, then install the global ROM
[OnePlus 9 Pro] Wyshniukas:
Thanks, will give it a go.
[OnePlus 9 Pro] Moe2003:
Hey how would i tweak it if i wanted to use it on the oneplus 9? Non pro

excuse me... im literally new to phones.

i tried to install official LineageOS after an accidental update to A12. it only works for android 11 and my device is bootlooping into bootloader. there is no Os installed rn.

on this case, will my phone get hard bricked if i use MSM? or am i safe? please i want to be sure.
[OnePlus 9 Pro] Kydaix:
You can use MSM to fix it. It should work.
[OnePlus 9 Pro] Borderliner:
Hi, i wonder that everyone says"just use MSM tool" or " easily Fix with MSM tool"

I have a LE2123 just using MsM tool easily and after 300 seconds it fails

FirehoseCheckRSP failed error 258

Status of Last Communication : Downloading NON-HLOS.bin failed

Nobody can tell me about that just they ask have you drivers, are you sure in EDL ...sure the tool is doing his job but failed after 300 seconds

But exist here anyone else who can please really tell me what my fault is and i have to do
[OnePlus 9 Pro] glowyemmanuel:
(obsolete: please remove)

i had a problem since i thought the phone was bricked but no, it was just booting slowly. i fixed it waiting and this reply doesnt need to exist anymore.

if anyone gets the "sahara" problem, do not unplug your phone: just hold volume up + power.

Any thoughts on how to flash from converted back to tmo? If I use the tmo MSM then it says mismatch due to conversion. Any thoughts? Thank you.
[OnePlus 9 Pro] Jed!Master:
hmmm looks like you guys cant revert back to tmobile firmware after flashing another variant ex India rom eur rom etc..... why do people have device mismatch when using the MSM tool. could the MSM tool be modified so that it bypasses device/model check so it can just flash the tmobile firmware back? or are tmobile customer that flashed to another variant re screwed and cant go back to tmobile firmware
[OnePlus 9 Pro] glowyemmanuel:
t-mobile is the worst variant it seems, so changing to another one seems a great advantage.
[OnePlus 9 Pro] Jed!Master:
But if I change I have to get my sim unlocked or else I won't get service correct. I know about flashing the TMobile modem but first I would have to get my sim unlocked the flash to another variant?

For example on T-mobile I am on 11.2.2.8 and this tool is 11.2.2.3

Hello everyone.

So if I am reading this correctly, (I have Chinese variant LE2120) I need to use the Indian MSM Tool and everything will be ok?
[OnePlus 9 Pro] ko2_wn:
i can confirm that, use indian tools it's ok, i'm using LE2120 too, now i use global rom a12 C.47

if LE2120 use gobal/europe tool, first time after reboot imei will change, but after you update again with the higher rom imei will came back to normal

;)
[OnePlus 9 Pro] oias.heeda:
Did you have any issues getting into edl mode? I can't get it to work no matter what I do. I am so frustrated.
[OnePlus 9 Pro] ko2_wn:
follow step like xori.eng do on page 3, should be good.

but i don't tick "Use Lite Firehose" on the checkbox

Just make sure your OnePlus is switched off,

open tools, make some setting on it, click on “Target” button to verify the device variant

then hold down both volume up and volume down buttons when plugging your phone back into your PC.

The phone should boot into the EDL mode at this point, which can be easily verified by searching for a new “QDLOADER 9008” entry (or “QHUSB_BULK”, if the driver isn’t properly installed) under Device Manager.

Once it connects press “Start”, and you’re good to go.

DON'T FORGET TO INSTALL DRIVER FIRST
[OnePlus 9 Pro] oias.heeda:
I managed to get it working in edl node with some ADB commands, add I want able to with the volume buttons.

Thank you for your help. 🤙
[OnePlus 9 Pro] Borderliner:
A few weeks ago I tried this version. But it didn't work
[OnePlus 9 Pro] TheGhost1951:
when this takes place, is the device serial number affected. TMO variant?
[OnePlus 9 Pro] BDProductions:
On my 9 Pro it is far easier to connect the cable, then hold all 3 hard buttons until MSM acknowledges the phone.

Also, I had to use the India MSM despite having a global 9 Pro.

Short and sweet help for anyone else where MSM appears not to work despite them following instructions in the first post...

Despite using the one marked as for the India variant, once it reboots it's all in English and works great.

I also checked the firehose box, but I am not sure that was actually necessary.

Hope this helps people

Hello guys, I bricked my device after rooting attempt through fastboot and Magisk direct install. I need to reset everything through MSM, because I no longer have access to fastboot. Unfortunately, once I connect the device in the device manager I see it only as LE2123. I tried to update the drivers with the provided on the first page, but it says that ADB drivers are already installed, also I don't see the device in MSM app. Please advise, thank you in advance :)
[OnePlus 9 Pro] TheGhost1951:
have you installed the OnePlus drivers?
[OnePlus 9 Pro] weriwd:
Yes, I have them installed.
[OnePlus 9 Pro] TheGhost1951:
if I'm not mistaken, you have to double cluck on the device and install the correct driver in device manager. I will try to find the link. the oneplus driver for the device has to be installed a special way because they are not "signed"! of course it might be the Qualcomm drivers I'm thinking of. I am new to the OnePlus phone myself.

you do have to install Qualcomm drivers...

Edit got it working had to run MSM as administrator
[OnePlus 9 Pro] boontje3:
try another version of the driver , instead of 9008 try 900x(number)

I also had this once with the 9008 driver yellow traingle, manually changed to 9001 driver and suddenly the pc recognized the oneplus

maybe this will work for you too
[OnePlus 9 Pro] JohnTheFarm3r:
I could bet that the driver you installed is not digitally signed and Windows is refusing to start it. Hence why it shows the triangle, even though that's the correct "version" of the Qualcomm driver for OP9 Series.
[OnePlus 9 Pro] Elrey567:
I'm sure that's probably the case, I got it working by running program as administrator Thanks
