I have not been following up the thread with PDAVIET WM6.1. So I cannot comment your problem.

You may want to access the following thread hope it will give you hint on your certificate problem.

Good luck,

Hi all, I have this good lock module Theme park and was playing with it. I made a theme myself (which apparently said a lot about my creative skills!) and it looked all but messed-up. Is there a way to go back to the factory default theme? Please help...my eyes are burning with my theme!
[Samsung Galaxy S21 Ultra] leongzxc:
try either one of it:

1. toggle off if there is an option for it

2. uninstall theme park

3. go to settings -> themes -> apply default theme
[Samsung Galaxy S21 Ultra] amirage:
Point #3 did the trick..how stupid of me! Still got a learn a lot about one UI. 💁
[OnePlus 9 Pro] TheKnux:
I went straight to the 11.2.4.4 as well, instead of the 11.2.3.3. Probably why I had such an issue also. Dummy me, wanted the latest and greatest right away and paid the price for it. 🤦🏻‍♂️
[OnePlus 9 Pro] luckylui:
Woohoo! 🥳 Thank you!!
[OnePlus 9 Pro] sunxutian:
for some reason my Wildvine downgrades to L3, not sure how to fix it, also as other post indicates, voice mail on dialer doesn't work
[OnePlus 9 Pro] sunxutian:
Yes, I toggled all options under google play services, no luckView attachment 5301401View attachment 5301403
[OnePlus 9 Pro] Ultraman666:
ok going to give this a go later fingers crossed and just to clarify i only need to backup ModemST1 and ModemST2 img correct?
[OnePlus 9 Pro] sunxutian:
you mind pasting some errors here? maybe the 1st error you got from cmd
[OnePlus 9 Pro] craznazn:
Persist
[OnePlus 9 Pro] craznazn:
* Test that you can boot to fastbootd prior to starting, "fastboot reboot fastboot" and you should see the OnePlus logo with the text "fastbootd" on top. Do not continue if this doesn't work.

* When encountering issues, describe all steps you took, paste any outputs, and take screenshots. Make sure to include the output of fastboot --version in your post.

Sounds like you tested that fastboot can't get you to fastbootd, but you continued anyways.

If you want troubleshooting, post the information I said to post
[OnePlus 9 Pro] sunxutian:
Thanks for the hint, I backed up the persist.img but that's after root/unlock bl, so you are saying flash persist.img will get me back to L1?
[OnePlus 9 Pro] sunxutian:
sounds to me like you don't get the proper version of fastboot, one thing to notice, if you install the one plus driver you may get the fastboot from C:\Android, DONT use this one. either put the correct platform-tool path to your $PATH or manually modify every fastboot.exe to be full path in script
[OnePlus 9 Pro] craznazn:
No, persist just unique to your device. You just need a backup in case yours get wiped for any reason.

Honestly, you are the 2nd person I've heard from that had the L1 issue and we were never able to figure it out. I did these steps to 2 different devices and both kept L1. Does safetynet pass? Do you have magisk canary?
[OnePlus 9 Pro] sunxutian:
Yes, my safetynet passes and I do have magisk canary
[OnePlus 9 Pro] craznazn:
Download a fresh copy of platform tools and unzip it into the folder that has flash_all.bat and .img files
[OnePlus 9 Pro] sunxutian:
what I suspect might be wrong is when I did the BL unlock I use fastboot oem unlock while some people use fastboot flashing unlock (not sure this makes any difference or not)
[OnePlus 9 Pro] craznazn:
I did oem unlock, shouldn't make a difference
[OnePlus 9 Pro] craznazn:
From that folder, run fastboot --version and share the screenshot
[OnePlus 9 Pro] sunxutian:
Then anything I can try?
[OnePlus 9 Pro] craznazn:
Hmm, also try the fix about page magisk module, shouldn't affect anything but you never know.

If that doesn't fix it, take the 11.2.4.4 OTA again via local update, and then lock the bootloader and check. You won't have a working modem but I want to make sure your wildvine keys are still there.
[OnePlus 9 Pro] sunxutian:
Thanks did that already and no luck..
[OnePlus 9 Pro] Kenkool12:
I got it unlocked I just had to restart my phone a couple times
[OnePlus 9 Pro] Kenkool12:
If I want to root my phone do I download 11.2.7.7ba when I go to root my OnePlus 9 pro and is rooting worth it.
[OnePlus 9 Pro] Kenkool12:
Thank you for all the help it helped me convert my first oneplus device Im glad I did it.
[OnePlus 9 Pro] bdaviesweb:
Can someone help, I was oem unlocked and boot loader unlocked and now my oem unlock is greyed out after the process. Any help? Looks like the msm process went okay but now everything is locked :) Thank you.
[OnePlus 9 Pro] bdaviesweb:
Bwhahs forget it :) Got past that issue :)
[OnePlus 9 Pro] bdaviesweb:
Thanks you very much for this. Everything works great!! Excited to try the newest updates for a while to see how they go and then onto custom!!

Take care.
[OnePlus 9 Pro] GuyInDogSuit:
Just curious, has there been any updates to the T-Mobile HLOS/modem? If so, where can I find it? My bar is always at the lowest, for some reason. Data works, it's just barely a 5G signal.
[OnePlus 9 Pro] lendawg:
Once I run this conversion can I then use the EU msm tool to go back to stock after flashing custom rom?
[OnePlus 9 Pro] razercortex:
No, you must run this conversion again, do not run the EU tool, it will not work.
[OnePlus 9 Pro] BobAzzon:
Feel like such a noob, got my bootloader unlocked, unzipped the conversion and modem in platform tools (newest version) but I can't boot into fastbootd for the life of me...plus where is the flash all bat script? I've been doing this years and never had issues like this...I'm ready to toss this pos
[OnePlus 9 Pro] bdaviesweb:
Adb reboot fastboot from cmd line. Then follow prompts to finish booting into fastboot.
[OnePlus 9 Pro] BobAzzon:
That boots me into fastbootd, but once there I can't do anything else....I'm at a loss
[OnePlus 9 Pro] razercortex:
You can only use volume buttons and the power button to control the menu, touch controls do not work if you reboot via cmd.
[OnePlus 9 Pro] BobAzzon:
Fastboot reboot fastboot doesn't work...man I feel like such a noob...I'm literally stuck with stock t-mobile with an unlocked bootloader....lol
[OnePlus 9 Pro] BobAzzon:
7pro was simple compared to this
[OnePlus 9 Pro] craznazn:
What are you trying to do? flash_all is depreciated, use MSM.

If you are trying to flash the modem:

fastboot flash modem /path/to/modem.img

. You can do this in fastboot or fastbootd. Don't bother flashing the secondary slot, doesn't matter
[OnePlus 9 Pro] BobAzzon:
The eu msm correct? And I can back my modem up via msm?....no wonder why I couldn't get it working lol....thank you for the heads up
[OnePlus 9 Pro] BobAzzon:
Should have msm from the beginning. But I like to do things the hard way lol
[OnePlus 9 Pro] craznazn:
No, you need something else to back up your modem (and other partitions). I personally use dd or edl, but there are apps that can do it. All of them except edl needs root, edl is harder to use.
[OnePlus 9 Pro] kelvin216:
Hi All, quick question, i tried this conversion and something went wrong, my phone wouldnt respond, so i search and found a few people who had similar problems, tried msm but the only one that worked was the India one with firehose lite, so did that then local upgraded to AA, went to flash modem and now i get no service, and no other msm works cause it keeps saying Unsupported Target IN any help with this, thanks
[OnePlus 9 Pro] BobAzzon:
Ok I'll root stock and back my modem and persist...before I msm. Thanks again
[OnePlus 9 Pro] craznazn:
What is your phone's model number?
[OnePlus 9 Pro] kelvin216:
Tmobile le2127
[OnePlus 9 Pro] freddienuxx:
Hey guys does anybody have a backup T-Mobile bluetooth.img from msm?

I can backup it but I would have to convert back to

T-Mobile firmware and setup again . I would appreciate it if someone can upload the Bluetooth.img thx 🙏 on advance
[OnePlus 9 Pro] BobAzzon:
So finally got everything ready to go and started the msm process, and now im getting the device does not match image...I've never had problems like this doing something that should be automatic.
[OnePlus 9 Pro] bdaviesweb:
Do you have screenshots. I didn't run into any of those issues.
[OnePlus 9 Pro] GuyInDogSuit:
Did you grab the matching MSM tool for your device?
[OnePlus 9 Pro] Pain-N-Panic:
Just curious....I've never heard of "fastbootd". Can anyone explain the difference between fastboot and fastbootd?
[OnePlus 9 Pro] lendawg:
Every time I turn phone off and hold volume up and down and plug it in to start the tool my phone just reboots. What am I doing wrong?
[OnePlus 9 Pro] GuyInDogSuit:
The trick is to hold those buttons until you press the Start button in the MSM tool. It's as tricky as it sounds (and an extra pair of hands may help) but it's doable by yourself if you're persistent enough.
[OnePlus 9 Pro] lendawg:
Ok I'll try that thanks.
[OnePlus 9 Pro] GuyInDogSuit:
Good luck! It sounds like a bit of work but it's easy once you've done it as many times as I have (coming from 7T lol)
[OnePlus 9 Pro] sultan.of.swing:
You can start the tool and then just do the button combo on the phone, once the phone goes into edl mode the msm tool will start automatically since you pressed the start button earlier.
[OnePlus 9 Pro] GuyInDogSuit:
Good to know!
[OnePlus 9 Pro] lendawg:
I've tried that...doesn't work.
[OnePlus 9 Pro] BobAzzon:
The key is getting the combo just right, or even switching cords. I've finally converted after days of frustration. Kudos and thanks to Jhoopes517 and Libra420T for the assistance.
[OnePlus 9 Pro] AwkwardUberHero:
I am feeling pretty confident in this.

Have all the files I need etc. One last thing I want to check before I do it.

"

Execute MSMDownloadTool V4.0.exe and msm normally."

I was reading this >>

On the login promptselect "Other" in the dropdown menu and click on Next.

Wait a few seconds until main window shows up.

Click on Target button and select O2 while using global tool or India while using indian tool or EU when using european tool.

Press Start button (this is done so that device will be "captured" automatically by tool instead of going back to normal boot after 10 seconds)

Power your device off.

Let it cool down for one minute.

Hold both volumes in to get in Qualcomm EDL mode and the screen will stay black. While holding, plug in the USB cable from your phone to your computer. Let volumes go alter plugged in.

Wait some time (should not be longer than ~300 seconds).

Enjoy your brand new device.

I just want to make sure those are the steps I am following when I use the MSM tool to flash to global. I am stuck on 11.2.6.6, the TMO variant is hella slow on updates.
[OnePlus 9 Pro] GuyInDogSuit:
Yup, more or less, that's the process to "restore" it. Which is what is required prior to the EU conversion.
[OnePlus 9 Pro] AwkwardUberHero:
Sorry for the dumb question, but when we are MSM'ing, that is what we use to select the EU software version to flash to? Or, is that a step that we take before we even convert it over to that version?

I've been researching for a few hours last night, and today, but still not making any ground on this.
[OnePlus 9 Pro] craznazn:
The MSM package in the OP is the EU conversion, you don't select anything
[OnePlus 9 Pro] AwkwardUberHero:
OK. Staring to make more sense to me now.

Open MSM tool

Select other

plug in phone while powered off

Press Power + Vol Up + Volume Down and then click start?
[OnePlus 9 Pro] AwkwardUberHero:
OK. Just click other when MSM opens, and hit start? There are some boxes in the MSM tool that I don't know if should be checked or not, just wanting to verify before I try this. Sorry again, after researching last night and today, I am almost ready to give it a go.
[OnePlus 9 Pro] webs50:
So I am converted to the EU Version. Now can I update to the global version through local upgrade?
[OnePlus 9 Pro] craznazn:
Don't mess with any settings in the MSM tool

Yes.
[OnePlus 9 Pro] webs50:
Will I still need to flash the T-Mobile modems on every upgrade?
[OnePlus 9 Pro] AwkwardUberHero:
Right on. I will leave them as they are now. I am going to work on this later tonight and see if i can get it to work.
[OnePlus 9 Pro] craznazn:
Yes. You can always boot after an update and see if they messed with it, but generally you need to replace.

Note, if you are on AA and flashed over the TMO modem, incremental updates will NOT work
[OnePlus 9 Pro] AwkwardUberHero:
Will make note of this. Do you know any way to backup my modems and persist without root? I am worried about losing those.
[OnePlus 9 Pro] craznazn:
Just root and back up. See OP and my warning about backing up the partitions.
[OnePlus 9 Pro] AwkwardUberHero:
Still waiting on one plus to allow my bootloader unlock. Once they approve, I'll root to backup the needed items.
[OnePlus 9 Pro] GuyInDogSuit:
See my DM about OandX Backup and Swift Backup. Those might be viable for non-root backups.
[OnePlus 9 Pro] AwkwardUberHero:
Thanks. I checked into both of those, but they both require root to be able to backup the modems and persist.

I really want to flash to the eu version, but am worried about messing it up.
[OnePlus 9 Pro] GuyInDogSuit:
Oh, dang, I forgot about those!

Yeah, I got a solution to that, as well!

Partitions Backup & Restore - Apps on Google Play

Backup your important partitions to avoid any data or IMEI corruption

play.google.com
[OnePlus 9 Pro] AwkwardUberHero:
I tired that one this AM, root required as well. haha.
[OnePlus 9 Pro] GuyInDogSuit:
Alright, dang, guess I had a brainfart there. Completely forgot that needed root. Could have sworn it was able to back them up without root, though....

Oh, right, I remember now. I initially used it to back up the persistent images and kept it since it could back up and restore just about anything else. Slipped my mind since then because I always backed the vendor and boot image files up as soon as I installed an update (but before restoring Magisk and rebooting). So *technically* it has root at that point but the files are stock? If that makes sense?

But for first time backup... not a good option, I guess. Nuts. Unfortunately, I don't know how to do it otherwise as I had always had root, even prior to doing this conversion. Hopefully someone can explain how.
[OnePlus 9 Pro] AwkwardUberHero:
I appreciate the info. I have looked online, but cannot find a video showing how this is done on a 9Pro. I have found videos showing how it is done on a 7, 8, and 8 pro.

Guessing it is similar to how these are done, but with the info from the OP.
[OnePlus 9 Pro] GuyInDogSuit:
I would assume that's the case, yes. But good stuff to know for future. And for anyone else who needs it.
[OnePlus 9 Pro] craznazn:
You can dump partitions without root using edl.py https://github.com/bkerler/edl/

This is entirely on your own, I will not be supporting this tool :)
[OnePlus 9 Pro] AwkwardUberHero:
Thanks for this! I'll see what I can do with it later. Appreciate the help!
[OnePlus 9 Pro] AwkwardUberHero:
I gave it a try about five or six times, and did not make it very far.

I was getting the Sahara communication error, and the firehose handshake failed error as well.

I am going to quit while I am ahead and not risk bricking or doing anything irreversible.
[OnePlus 9 Pro] GuyInDogSuit:
Sometimes it's as simple as trying a different (non-3.x) USB port or even a different cable.
[OnePlus 9 Pro] mypd1991:
I don't understand how this is a how-to guide, but yet they don't show you how to root to actually do the process correctly. Since this is specific to the T-Mobile variant.
[OnePlus 9 Pro] GuyInDogSuit:
Because root isn't required.
[OnePlus 9 Pro] mypd1991:
So then how do you backup your modem's so your phone will work, not shown in the guide, it just says to do it.
[OnePlus 9 Pro] craznazn:
Uh, the OP has a link to a modem you can use. You can always dump your own modem as well. There are also other threads on this forum for modem updates.
[OnePlus 9 Pro] mypd1991:
The OP also says to backup your modem and that they're unique to your phone. Yes, which requires root to do which was my main point, and every post I've seen says you need to root to backup and the resting guides post nothing for the T-Mobile variety which is what this thread is specifically about.
[OnePlus 9 Pro] craznazn:
Dude, I am the op.

Nowhere does it say you must backup your modem. You should backup your persist and modemst1/2. These partitions are not modem.

The thread was created prior to the MSM conversion. Back then, you needed an unlocked bootloader to do anything, and flashing things around can lead to... instability and you should already have the ability to root anyways.

Now, you can MSM to EU, then just unlock the bootloader without the need for a token. You can then root and backup what you need, and it's highly recommended. The OP does still give you an option for backup:

So, if you are not comfortable, don't do it.
[OnePlus 9 Pro] AwkwardUberHero:
I finally got this to work and am having a total brain fart now. I am trying to flash the non hlo bin modems, but it keeps telling me waiting for any device.

I am using windows 10, and thought I had all the drivers installed

I am doing "adb reboot bootloader," and it boots to bootloader.

From there, if I try and run the flash command in the OP, I get the waiting for any devices error.

What did I miss?
[OnePlus 9 Pro] Jhoopes517:
Check device manager and make sure fastboot drivers are installed. Fastboot can't see the device.
[OnePlus 9 Pro] AwkwardUberHero:
Yep, that is what it was. Thanks. I got cell service working now, and data as well. Cannot enable RCS but not a huge deal currently.
[OnePlus 9 Pro] GuyInDogSuit:
Happened to me, too. I ended up just leaving it alone for some time and checked it later, to find it was enabled. Apparently that can happen if they're having trouble switching it to the "current/new" device as the "old" one needs to be deregistered. You might need to check the "Messages for Web" page linked in the settings (either on a PC or change to "desktop view") and remove the "old" device. At that point, give it about 10 days at most, iirc, and it should be on again.
[OnePlus 9 Pro] AwkwardUberHero:
I feel like when I switched from a pixel to my 9 pro this happened as well. It is fine, the only person around who really uses RCS with me is my wife.

I am enjoying the smooth experience of the EU rom so far. No issues, waiting for the battery to break in, but other than that, smooth so far.
[OnePlus 9 Pro] adewaleandrew:
Pls can u dm me the steps cos I just got mine s unlocked it's TMobile and am waiting for unlock code still
[OnePlus 9 Pro] adewaleandrew:
It's sim unlocked already
[OnePlus 9 Pro] AwkwardUberHero:
I just followed the steps to the t. It took a while to get it to work, but stick with it.
[OnePlus 9 Pro] adewaleandrew:
Where am confused is must I unlock bootloader before doing it or I can go ahead without it then unlock boot when on eu
[OnePlus 9 Pro] Kenkool12:
You can unlock the bootloader once you flash to the EU version then you have to have the bootloader unlocked and have an unlocked sim for it work at all. If you don't have a unlocked sim then it won't work. As long as your sim unlocked. You have to have boot loader unlocked after you flash EU variant so you can get service.
[OnePlus 9 Pro] adewaleandrew:
pls after converting to eu i was unable to unlock bootloader,had to use msm to revert back to tmobile
[OnePlus 9 Pro] adewaleandrew:
oem unlock enabled
[OnePlus 9 Pro] adewaleandrew:
just worked now am so happy restarted the whole process again
[OnePlus 9 Pro] jwidel:
Adb reboot bootloader then once your at boot loader menu that pops up when your phone boots. Then fastboot reboot bootloader and you should see oneplus logo and underneath that it will say fastboot. Confirm your in fastboot by typing fastboot devices.
[OnePlus 9 Pro] jwidel:
Nope sorry I didn't it was the last reply on the bottom and I was exiting so I figured I try to help if I could.
[OnePlus 9 Pro] jwidel:
i can not for the life of me figure out how to use msm. can the eu firmware just be flashed in fastboot?
[OnePlus 9 Pro] adewaleandrew:
Fastboot steps are on the first page,but embrace MSM it's a life saver, I go btw T-Mobile to EU randomly using MSM,it helps unbrick most oneplus devices
[OnePlus 9 Pro] nimeshc:
Just got my Tmo Oneplus 9 Pro (sim unlocked) & would very much like to go to EU firmware.

Couple of basic questions before I start. Also extremely sorry if I sound stupid. For this process to work, I need to backup persist, modemst1 & modemst2 right? For that I need to first unlock bootloader & root.

Once I backup the persist & modemst files, I just need to follow the "Steps" provided in the OP?

After Step 9, my 9 Pro will be flashed to EU version & I can update the OS to latest version using "OnePlus Updater"? Once that is done, do I need to reflash modemst1, modemst2 & NON-HLOS.bin?

Also with this approach, I hope I don't need to follow the steps mentioned in Fastboot Method?
[OnePlus 9 Pro] GuyInDogSuit:
Correct, you will need to back those up. You don't need to be rooted to do so, though. You can use ADB to do this. I don't recall the exact commands (I am searching for them as I think this response through, lol), as they can differ depending on the device. I do recall it was the dd command and you can run it from Windows' CMD prompt or in Terminal apps on your device.

EDIT: OP linked this Python script in an earlier post. I have not tried it, but it's worth a shot. I can't find the specific DD commands needed for this device's backup, though I know some gracious soul had posted them in this thread somewhere. If you do decide to root prior to the conversion process, there are much easier methods to do it, but that's up to you.

Once those are backed up, you can proceed with the steps, yes, including updating with Oxygen Updater. Reboot into Android, and run the commands mentioned in the OP to flash your NON-HLOS files. Don't reflash the others, just the one I mentioned.

The fastboot method is only there as an alternative method in case any of the process above that fails. Don't worry about it if you've succeeded in the other method.
[OnePlus 9 Pro] AwkwardUberHero:
Saw the latest update just dropped. Downloaded via oxygen updater, tried to install and got the "update install failed," this is the second update since I converted.

Should the update via oxygen updater work for me, or do I need to wait for the normal OTA method.
[OnePlus 9 Pro] AwkwardUberHero:
Here's what I'm seeing using the local upgrade method.
[OnePlus 9 Pro] GuyInDogSuit:
Are you rooted?
[OnePlus 9 Pro] AwkwardUberHero:
Nope. Stock kernel as well.
[OnePlus 9 Pro] GuyInDogSuit:
That's really strange. Did you happen to skip that "about phone" fix?
[OnePlus 9 Pro] AwkwardUberHero:
Yeah. I did. Could that be why?
[OnePlus 9 Pro] AwkwardUberHero:
Will that effect me getting software updates? Someone on Reddit said to download the full update not the incremental and install it also?
[OnePlus 9 Pro] GuyInDogSuit:
I'm not quite sure a full update is needed, as it's only necessary if you're rooted, but perhaps for some people it is? The "about phone" thing shouldn't mess with it, as the phone still identifies itself correctly to the servers and to the Play Store. I think it's a cosmetic thing, really.
[OnePlus 9 Pro] AwkwardUberHero:
I'm super confused why it doesn't see the update unless I go into the oxygen updater. It sees the update there, but nothing showing in the normal system updates area.
[OnePlus 9 Pro] AwkwardUberHero:
I went back and read the OP post. I don't think I took the full OTA update when I first flashed over, I think I only did the incremental.

Now, if I download the full OTA update now, is that going to brick my phone, wipe me phone etc?
[OnePlus 9 Pro] AwkwardUberHero:
Ignore my random posts. I downloaded the full update via OO, installed, rebooted, and flashed modems.
