I have the 7pro from t-mobile but unlocked the bootloader 2 years ago and always used the global official roms. By mistake I wiped metadata along with dalvik and cache when re-flashing the rom and now the phone reverted to GM1915. I am experiencing drops in data on ATT, so I believe that could be the reason. I see that there is a guide with a PC tool to convert the phone, but I honestly don't remember doing that, just flashing twrp and then the global rom was enough. I want to go back to GM1917, is the PC tool needed or is there a way to flash a rom to go back to GM1917. Any assistance will be appreciated.

Hey I was experiencing some display issues so I flashed a custom ROM to test / narrow the problem (hardware issue sadly).
—Now I'm not sure how to revert back to completely stock as I've never unlocked the bootloader and worked much with fastboot.
On Samsung's you just download the official stock file, get Odin and put the file into AP, flash, done.
On one plus this is a bit different, first of all there's barely any mentioning of GM-1910 in the MSMDownloaderTool thread(s), I also don't want to have Hydrogen OS.
—My OP7Pro came with Oxygen OS pre-installed, GM1910 "international version" ← def. Chinese with oxygen flashed over it.
*What have you altered so far?*
Unlocked Bootloader/OEM
Flashed TWRP with fastboot
Flashed Havoc 3.0 OS, Magisk, OpenGapps
My perspective on the nature of special relativity.
*What do I want to reset?*
EVERYTHING, ROM, recovery, bootloader, you name it, I don't care about apps and pictures. worth noting I have a One plus Switch Backup, does that help?
Look for the MSM tool... that can reset the phone completely back to stock.

You can use the fastboot ROM or Guac (MSM tool for oxygen OS). Links below:

excuse my stupidity but given that I want to get rid of my custom ROM and back to stock oxygen which tool do I have to use?
secondly all images (androidfilehost) for the second link are for GM1911,17,13,15 but mine is 1910 which is not listed, what do I do now?

I am sorry but I am not familiar with Chinese stock ROMs. For some reason, I got the impression that you wanted to restore it to an international version and not the Chinese/HK version. You may want to post a question in the OnePlus community forum or check out their download section for your specific model.

no no I want to restore it to international version, the phone itself is GM1910. should I flash GM21AA file or the global file?
I think I will go with the global file, makes most sense in this moment

GM21AA should be fine. If you decided to use the MSM tool (the one in the first link), hardest part is to get the L2/qualcomm drivers installed on your PC with the method described. Alternatively you can download and install the drivers yourself which will make the job easier. This will LOCK your bootloader and wipe off everything on your phone. You will get a brand new phone running 10.0.3 OS
Easiet way would be to go fastboot ROM route. It will also wipe your phone but won't lock the bootloader. Once installation is complete you could use the adb command to lock the bootloader. It's one extra step but may be much easier IMO. Download the zip file on PC>unzip it>Hit flash all bat file while the phone is connected in the fastboot mode. You may get some error messages regarding header parsing, ignore them and sit tight until your phone boots.
Good luck!!
WORKS NOW! Can confirm this reverts all back to stock (it will revert back to Oxygen OS (OOS) 9.5 so you'll have to update to Android 10 via OTA if you want)
For anyone wondering, I had Android 10 installed before / Havoc 3.0 and the MSMTool will revert you back to Oxygen OS 9.5. Widevine jumped back to L1 so everything should be stock.
If you have any questions, don't wait, I am sure someone out there had the same questions/issue as me and I hope this will help you.

Hey, I have a problem, I re-locked the bootloader, it is currently blocked, but my Widevine status is still L3, can you tell me if you used MsmTool first and then you did relock, or did you block the bootloader first?
New GM1915 T-Mobile OnePlus 7 Pro user here...
I seemed to be out of the loop since the release of AB partition, android 10 and so-on...
I did everything here says, unlocked the bootloader, unlocked the sim, converted to international, twrp, and root...
[GUIDE] How to convert TMobile OP7 to International.
First of all this is not my work I only tested theirs. Credit to themustached for finding that a patched .ops was the solution. This guy doesn't even have the damn phone yet and did this for us so show some love. You can donate to him through...
forum.xda-developers.com
and when I want to try other rom or revert back to OOS stock, I missed up and brick a the phone 3 times already....each time I have to use MSM tool and flash the rom to Android 9.x...which is missing something twrp needs, So I need to do a OTA update to Android 10.x before I can install twrp and root.....
Q1: say I have a working system at android 10, twrp and root, If I want do a clean flash of the rom, do I now only wipe the (user data partition in the twrp advance wipe) or the (data wipe that you will need to put type yes and wipes everything)?
Q2: is there an updated T-Mobile .ops file to use with MsmDownloadTool? So I can restore to android 10 in 1 step?
Thank you
Looking for an updated .ops file as well my phone is bricked with android 11 and can't seem to get msmdownloadtool to work with my bricked oneplus 7 pro
Hello! I've been rooting and installing custom ROMs for years but it's been a long while since I last did it, I got a oneplus 8 global (IN2015) late last year, unlocked the bootloader as soon as I got it out of the box since I knew eventually I would want to flash some stuff. but I have kept it stock this long. Running latest Oxygen 11 android 11
Since I want to start flashing some kernels or roms I wanted to ask about making a backup since I've never had a phone without sd card slot where I would usually store backups.
Can I still use titanium backup to keep all of my apps/data/photos/videos and the state they are in, store it in my pc , then go about flashing a custom Rom and then bring my titanium backup back into the phone and restore everything?
since I'll be installing custom roms based on android 11 I believe it will be fine with no conflicts? or does it matter that my apps were installed in Oxygen OS?
that's what I used to do with older phones anyway. is there a way to flash a rom while having the titanium backup still in storage since most roms require full whipe when clean installing them?
Recently twrp added official support for OP8 and when I open the official app it recognizes my phone as instant noodle but when I click search for phone it says it can't connect to the server? should I flash official twrp from the app or via fastboot? which I'm also quite rusty with.
any tips for a step by step would be appreciated
Hello, I was in the same boat as you since I came to the OP 8 from a Galaxy S4. Titanium backup should work for what you want to do, as long as the custom rom is also based on A11 (disclaimer: I haven't tried it; I'm running rooted stock OOS 11 with a custom kernel). If the rom you want to install requires a data partition format, you can't keep the backups there during the flashing process. If it only needs a data wipe / factory reset, everything in the sdcard directory (also known as /data/media) should be preserved.
I'd say just flash TWRP in fastboot. Flash it to both recovery slots, and read up on how flashing works with A/B slot devices if you aren't familiar, since you'll need to know about it when flashing roms also. It's a big difference from what I was used to with older devices.
Thanks for the reply, yeah I was thinking of just going with a custom kernel since I have so much stuff going on the phone I find it really a chore to backup, but still might want to try it.
What kernel are you using and how are you liking it ?
I have a T-Mobile OP9 that I just purchased used. The bootloader was unlocked and I received the file along with the phone. The phone was originally on A11 L2115 (but still showed L2117 in Settings / About). I rooted and grabbed the modemst1, modemst2, and persist.img files with Partition Backup before anything else. I then subsequently updated officially to A13 through an update via local storage then through the OTA updater and it was then fully seen as L2115. I then realized that the rom I wanted needed A12 firmware so I went back to A11 then unlocked bootloader again and attempted to update firmware only off the CrDroid A12L update page. I chose not to flash the modem during that flash and then afterwards my service stopped working. It read the IMEI and baseband and would recognize that it was T-Mobile but no calls/text/data. I then got the bright idea to go back to Tmobile A11 through MSM then unlock bootloader, root, and use Partition Backup to restore the modems and persist imgs. After that, even though I can successfully flash the full Tmo MSMDownload Tool ops file, it only bootloops. If the MSM tool can't fix it - is it done for?

Sounds like it's not factory resetting when running MSM tool. Boot into recovery and wipe device. Then it will boot.
Regrettably, I've already tried with and without wipes in recovery. I've successfully flashed the recommended T-mobile firmware and there seems to literally only be one option to try for this variant I've seen anywhere. I know the file, Downloader, drivers and USB cable work as I used it to successfully go back a couple of times before the reflashing of the modems and persist files. It also passes still without error but it'll reboot after it sets on the T-mobile boot up for a couple of minutes.

U can fix ur bricked device anytime with op 9 pro india msm but i would say if u want try global u shuld try msm conversion without unocking bootloader if problem exist flash 2115 a11 with fastboot enhance u will be out of bootloop i have been there solved it this way
Thanks so much for the reply. I downloaded an Indian 9 Pro firmware but I couldn't get it to flash. Is there a specific one? I used the one recommended in the main thread for unbricking, I thought but I've been trying so many things at this point its blurring together.
Is it possible to fastbootd flash when locked to a different model's firmware?

I did try this last night. I am able to flash this successfully, but it sends me into a bootloop.
Same as the original Tmo MSM did before I flashed the Indian 9 Pro MSM (I haven't had luck changing the Target back to something that will work with the original Tmo MSM file yet). With or without factory data reset, I get a bootloop on a Tmobile version of the MSM. Boots up fine with Indian 9 Pro.
I can also switch to global firmware with the official 1+ zip after it boots with the Indian MSM either via temp custom recovery or via local storage updates but it still leaves me with null IMEI and no baseband. I've tried to flash just the Tmo NON-HLOS.bin file in fastbootd while on the Indian firmware and just got a bootloop too. It definitely seems related to the me screwing up the baseband / radio situation but seems odd that the normal fixes aren't sticking. At least I got it to boot to something, but it's still unuseable.

Right, but I can go back to the Indian 9 Pro MSM then unlock. I just re-attempted the flash for the Tmobile MSM target IN and same - bootloop. It flashes everything successfully with no errors. I have tried with and without all of the boxes checked. It won't work with either Lite Firehose or SHA256 checked. Have flashed, reset, then flashed again. Doesn't seem to make much sense that one version will work but the actual one for my phone will not. I really, really dislike the T-Mobile variants of the past few 1+ phones. It really limits them and makes it a huge hassle to run anything custom.
I believe it is my EFS partition that is corrupted when I attempted to restore the modemst1 and modemst2 files through Partition Manager.
Update: I've fixed my baseband issues by fastboot wiping the modemst1 and 2 partitions. This has allowed me to now successfully flash and boot the Tmo firmware via the modded MSM for target IN. Now I am just left with repairing the IMEI which now reads 0.
Update 2: Was able to restore IMEI once I got the bootloader unlocked and reflashed my modemst1 and 2 with Fastboot Enhance.
Whew. Thanks for all the help!

That might be possible u shuld go for bootloader unlock first of all everything great to hear that u got it fixed
Hello,
Just got a Oneplus 9 today. Installed Jaguar to try it out. Wanted to go back to stock to compare a few things.
I grabbed the "stock" files and tried to flash using this guide: https://forum.xda-developers.com/t/fastboot-rom-pc-required-op9-stock-oos-11-2-2-2aa.4275727/
This bricked the phone.
I was able to restore the phone via MSM using the Indian one (lemonadep_22_I.07_210412), but in OxygenOS it states the Phone is a 9 Pro.
I tried flashing the STOCK file again just to see (since I now know I can recover in EDL), but it bricked the phone again.
This allowed me to confirm that for Global LE2115, the European MSM (lemonadep_22_E.05_210324) also works to restore the device!
Unfortunately again, it says the Phone is a 9 Pro.
How would I proceed if I wanted to return a LE2115 to stock and relock the bootloader?
Thanks

Copy pasta:
To get back to global firmware, flash this in the local upgrade tool.
https://oxygenos.oneplus.net/OnePlu...all_2107082125_downgrade_059624cc7298428b.zip
It is the global downgrade package. It will wipe your phone and when it comes back, you will be back on global software.
After you flash that, go to OTA upgrade and it will say it's going to download C.48 but it will actually install 11.2.10.10 and then you will have the latest OOS11.

I used the unnbrick tool from one community server and restored my one plus 9 5g 2115.to stock and locked the bootoader. But I could not get to install any rom because it always took me to crash dump. Hope it helps to get back to proper version for you
