can you help me to downgrade? - OnePlus 7T Questions & Answers

Hi, I'd like to rollback to oos 10 from oos 11. Can you help me to downgrade?
I don't know if I should follow some yt videos or using the unbrick app here.
And most of all what is the latest oos10 version for EU OP7T
Thank you so much

Hi
I downgraded few days ago from OOS11 to OOS10 but I have Bootloader Open but I think that doesn't matter. (If I am wrong correct me) Always possible to open it and then downgrade
Which system exactly you have? Version.

Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T and OP7TPRO here is the EDL package (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 7T bought from T-Mobile.
It can also be used to rollback your phone to a previous release of OOS.
You can download the following versions:
ANDROID 10:
10.0.3 HD63CB
10.0.5 HD63CB
10.0.7 HD63CB (credits @viperbjk )
10.0.8 HD63CB (credits @viperbjk )
10.0.9 HD63CB
10.0.10 HD63CB
10.0.13 HD63CB
ANDROID 11:
11.0.1.5 HD63CB
Mirror for first and last MSMs: https://onepluscommunityserver.com/
It will only work with T-Mobile variant HD1907
Instructions:
Power your device off
Maintain volume up and volume down keys to get into Qualcomm EDL mode.
Launch MsmDownloadTool V4.0.exe.
Specific to 10.0.7 and 10.0.8
On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.
Click on Enum to be sure your device is detected and press Start.
Wait ~300 seconds
Enjoy your brand new device
FAQ:
My device isn't detected when I click on "Enum" button
Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008 ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.
MSM tool is stuck on "Param pre-processing"
Ensure you're using the Qualcomm drivers linked in first part of this FAQ.
What is SMT Download mode?
Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.

Does this mean that soon we can install international ROM to our phone even without sim unlocking it?

No, it just allows you to go back to stock T-Mobile firmware in case you bricked your device.

Did they successfuly flash your phone with the attached file? Their level 2 techs are complete idiots and keep trying the wrong software. So is it correct this time?

That's the best thing I could have read all week.
I've heard this is what we've been waiting for to convert to International firmware. I see above that it can't be used for that. What needs to happen before we can convert?

Lots of testing. This year's convert process has be a tad bit harder due to OnePlus trying to make things a tad more difficult for us. Just stay patient and it will come soon in some form of manner.
So another little update. I managed to convert(a dirty way) and it involves at least being bootloader unlocked. I waited a week and got my code and immediately did this. This method isn't released yet but if you guys are interested in testing and have some skills in edl and know your way around python or adb please PM ME. We can get you into our testing group temporarily and try some methods to get you converted. This will be per discretion by me. If I don't think you can help I'm NOT going to add you.
Nice. I unfortunately need to wait until a bootloader unlock is possible since T-Mobile refuses to unlock mine.
This is really, REALLY good news. Well done, Joe!!

Relock Bootloader + Unroot and Factory Reset OxygenOS 11.0.5.1

Hello Everyone,
Before you guys get mad at me, I know there are a lot of threads on how to relock the bootloader, unroot the phone, and factory reset. But I got confused with most of it since there is a lot of different information out there, and most of them are for OOS 10.
So here's my case:
- I have stock OOS 11.0.5.1 rooted with Magisk and bootloader unlocked; HD1907 device.
- I basically want to remove the root, lock the bootloader, and wipe/format my phone clean (just like a brand new phone would be).
- How do I do it without getting my phone bricked??
Someone, please point me in the correct direction on what to do. Any help will be appreciated.
Thanks a lot!

Hey there, I have the same issue. This was not working for me as MSM just would not send anything to the phone. Also, after trying other methods I am stuck in fastboot so cannot open EDL. What do I do?
Qualcomm USB 9008 drivers. Phone must be off. Hold buttons as video showed:
If don't want to use msmtool:
"fastboot reboot fastboot" to get into fastbootD and then reflash all partitions

Question flash A11 on "bricked" phone

im sorry for the inexpertise, this is literally the first phone i ever had and im not familiar with this at all.
i tried to install LineageOS, i accidentally updated to a12 and the build only supportis a11. my phone is bootlooped and locked. it will exclusively start on bootloader and all boots will go there no matter what. the official OS is wiped.
so all methods require manually putting the files inside the phone and this is not possible on bootloader because pc wont recognize the phone as a device, so you cant transfer files.
in this cases, how do you install A11 on the phone? what can i do to recover access to the phone? THERE IS NO OS RIGHT NOW

thank you both. one thing that worries me is the red warning, no partition was ever touched by MSM because i never used it. so under the circumstances i posted, is a hard brick possible? i want to be totally sure before proceeding

Maybe, but MSM will flash all the partitions, you'll loose your data obviusly, but you'll get your phone alive again it will be like you just bought it

Question How to flash stock rom from custom rom

Hi there,
Bought this beast of phone like 8 months ago easily but after installing several roms and suffering so many bugs (with cr-droid the camera never worked at 4k 60fps i.e.) and app crashes, now I need something stable 100% so want to go back to stock rom.
However couldn't be able to find any tutorial about that, so I'm a bit confused with this problem. Which are the steps to do that?
Thanks in advance

Iam a little hesitant to use , when I go into read the bat file it states
ECHO # Oxygen OS Flasher For OnePlus 9RT by abhinavgupta371 and HELLBOY017 #
ECHO # updated by Va1d3m and penguinus
I just want to be sure it has been configured for the op9p
I would just use the MSM tool to go back to stock rom. With phone in USB debug in CMD type adb reboot edl when you have your phone plugged in and the MSM tool open. Once MSM tool recognizes the device just press start. After going back to stock rom update to latest firmware

I realize, but it would be nice to quick toggle between diff versions and returning to stock without using MSM, so that's why I am questioning what the android file host says it is versus what the fastboot rom says it is in the .bat file,,,, edit,, answered my own question went from 13.1 back to c_65 and everything looks good, and its asking me to upgrade to f.17 if I want,,,, edit,,,, and just doulble checking that msm still works after using fastboot rom and it does

In any case, at the end, you should go via MSN

It went well with the fastboot roms going from 13.1 to c_65 ,then I msm to 11.10 and tried to go back to 13.1 via fastboot rom and it didn't like that,, it soft bricked to bootloader loop so I had to msm again via magisk,,
