[GUIDE] Convert TMO to EU via MSM Tool, no SIM Unlock or Bootloader Unlock needed!

[kevinco1]

Should have mentioned that while I'm not rooted both bootloader and SIM are unlocked so don't have to worry about that.

But I'm thinking now... My main motivation to do this is root. If that's the case would it just be better to root OOS12 via Magisk instead of downgrading?

Friends dual sim is working in OOS 13 beta 1. I have installed it directly on OOS 11 with local update. And OOS13 beta 1 us very stable and smooth. I have not found any bugs yet.

 

[kevinco1]

So is it possible to go through this process successfully if you're on OS12?

 

[craznazn]

Yes, provided there is no DDR issues. It'll downgrade you back to 11

Has anyone who converted T-mobile to Global Rom, upgraded to OOS 13 Stable (F.13) had any issues? I'm running the EU rom, and was recently given the option to upgrade. With OOS12, I lost the ability do dual-sim...and seems like OOS13 also disables dual-sim, but just wondering if there are any other bugs to be aware of or anything else that might make it not good to upgrade?

On reddit there have been some folks saying that their contactless NFC payment stopped working (with google pay), but then another post said this was only an issue for people who use multiple user profiles on their 8T?

Upgraded to OOS12 this morning.. everything seems to be working fine, but colors seem to be washed out, especially with the new Monet color palette. Has anyone found a solution to getting the colors back to the vibrancy OOS11?

Also, big thanks to all that wrote the guides to convert the T-Mobile KB2007 to EU firmware. It solved many bugs for me.

Hey, I had a heck of a time trying to get all the proper drivers installed to get the MSMDownloadTool to work on a fresh install of Windows 10. Hopefully this helps someone else with a similar issue.

QUSB or QHUSB:
1. Connect phone to computer
2. In CMD, type “adb reboot edl” > Enter

3. IF YOU SEE QUSB or QHUSB instead of “Qualcomm 9008” WHEN CONNECTED:
XDA user gamingdoggo’s compressed .cab file (9/7/21 - #1246)
https://forum.xda-developers.com/t/...r-unlock-needed.4188491/page-63#post-85594511

3a. Download .zip file + extract to somewhere findable, windows + x > device manager
3b. Right click QUSB/QHUSB > properties > update driver > browse my computer for drivers > browse > go to where you extracted > select fe24…259d folder > should say “installed Qualcomm 9008 drivers”
3c. Restart computer

4. Connect phone to computer (if not already)
5. adb devices > make sure phone shows up like “XYZ362 Device”

2. Enable developer options, enable USB Debugging
3. Make sure phone is connected to computer with ADB enabled (“adb devices” to check)
4. adb reboot bootloader

5. Windows + x > device manager
devices? (Someone please take a screenshot of this part, I forget what Windows exactly says) > Android
6. Update driver > browse my computer for drivers > browse > OnePlus Android Bootloader interface (i believe from OnePlus USB Drivers (c:\Program Files x86\OnePlus USB Drivers\OnePlus_android_winusb.inf) > 7. Install

8. adb > fastboot oem device-info (to verify BL lock status)
9. fastboot oem unlock > Enter
10. Volume key > volume down to highlight “YES” > power button to confirm

I had an original KB2007 TMobile version. I used this to flash it to LB2005. I had no issues. I flashed back when I was on Android 12. I took the over the air update for the KB2005 Android 13 and had no issues. I will say that I did have an issue taking the updates when I had TWRP installed. But once I flashed the stock recovery back to it the updates went through just fine. Now my phone shows that it is a KB2005. On the latest Android 13 OS.

Can someone who went from T-moble KB2007 to global or EU test USB-C video? The T-Mo version lost the ability for many people after the update to Android 12. I have a monitor with USB-C input and it works fine with my Samsung phone but not my KB2007 (and reading online, this is a common occurrence).

I'm thinking of going to the EU version but would like to have both the US 5G bands as well as USB-C video out.

Flashing does not change the available bands for the device. Your Kb2007 will have the same bands it came with regardless of the firmware you flash.

I thought in the past there were issues with no longer getting T-Mo 5G after a flash to global or EU. Maybe I was mistaken! If that's the case, I don't see any downside to going to EU.

I have tried them all and my KB2007 is still running the KB2001 beta 1 for India so I have dual-SIM. 5G has worked fine on every firmware I have used for T-Mobile.

Flashing via the MSM Tool doesn't touch the modem firmware.

I have just unlocked my bootloader using this method. I need Magisk, so i need the boot image however i dont know the exact version to download from the repo. Kindly advise

It depends on what firmware version is installed on your device.
Check it in android settings.

KB2007 on LOS 20, conversion went fine
but reboot after first OTA (OOS 11.0.13.13.KB05BA) I got "system update failed"

I went ahead with the next OTA (KB2003_11_C.33) and did not have any problem

Did someone tested the video output to an external display? Going through the same issue after updating to A12 T-mobile version.

Update:
I have tested it. Doesn't work. Only works on Oxygen OS 11. Once you go up, you'll loose it. I ended up rolling back to OOS11 after testing OOS 13.

I've not ever gotten this to work. I wish I could!

Sadly no way to get it working so far. Ended up rolling back to OOS11. I'll rather have the desktop mode working than the latest Android version for now.
