Hi
Recently I flashed my OP 7 Pro from Chinese version of Hydrogen to Global Oxygen 9.5.7.
I have Chinese version of the phone GM1910 and I did that mostly because of the Google Services lock [as Google is banned in CN]
Now I would like to go back to the original version, but I don't think that I can do it by the local upgrade [as the H is a higher version than Oxygen?]
Would factory reset bring it back to the Hydrogen version? Or the Oxygen is now the official version of the software for my phone?
Apologies if my question is stupid, but I am really new to all those flashes and changing ROMs, so I rather ask before fragging my lovely phone
thank you for any info
Flash Chinese Full version (latest) from local update then wipe date from recovery.
changing from Hydrogen version to Oxygen or from Oxygen to Hydrogen is easy
just flash it back from local update, no data wipe is needed if it is no error (official instruction), i flash from h2os to oos without wipe, no problem.

Unfortunately it's impossible.
Hydro is a lower version than Oxy, system won't aloud to do it.
I'll have to wait for the next update,or root it..?
So annoying ?

Unlock bootloader and flash it via fastboot ? (provided if there's a fastboot version of the rom)
Local upgrade doesn't allow downgrading firmware. You mentioned that the HOS's version is higher then it shouldn't be a problem right?

Sorry it's the other way around.
I can't do it over local upgrade.
What's the difference between official ROM and fastboot version? (Sorry I'm still learning here) :crying:

Official one is flashable via local upgrade, fastboot rom is executed via fastboot mode adb.

Waite few days to get OTA_010 of Hos
Use MSMdownloadtool. There is one for the Chinese phone. it's in the thread collecting all the various MSMdownloadtool archives. Use that to get down to an old version of Hydrogen, then you can flash Oxygen via local update.

fyi, going through same thing now. delete the chinese text from the first folder or copy the guac folder elsewhere. it errors otherwise. took me ages to figure it out.
If that doesn't work for some reason, I'm surprised nobody mentioned using TWRP to flash Hydrogen. If that doesn't work for you, try installing TWRP and then flashing Hydrogen that way. ?

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.

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?
Hello there,
I tried the open beta on the OnePlus 7pro for a while, but I have some massive issues with speaker distortion, so I decided to go back to stock. I know this involves a wipe of the entire system, and I have fully prepared that.
However: I seem to be to stupid to perform this. I used to flash all kinds of roms to my OP3 back in the day, but I can't find an option for simply flashing the zip in the recovery.
My big big question is: How do I perform the full reflash of this phone?
Do I get an factory rom like with the pixel, or do I need to sideload something and flash it in recovery?
I am really clueless rightnow, expecially since the factory image told me, that the bootloader is locked, but to my unterstandig, flashing an original manufacturer image should not require the bootloader to be unlocked...
So I am really hoping on your help, as rightnow, I have a beta phone that is waiting to be setup...
:crying:
Follow this tutorial.

Or easier way would be to download rollback package from oneplus which will wipe everything on your phone. You will have os9.5.3
You can then do Ota upgrade to latest os version. Rollback package is listed in in the middle of the post

So my OnePlus 7 Pro is rooted, has twrp, xxx ROM and renovate ice. If I want to go back stock and relock bootloader, can I simply flash the latest ROM (in this way I should loose twrp and root) and then relock bootloader with ADB command?

Thanks bro!!
Local upgrade is a cake walk! All my worry was, if I go for a random version msm tool, which is not specific to 10.3.4(more like the case of fast boot Roms), i may stuck at bootloop/something undesirable.
From your reply, i understand, i can use any msm tool zip that supports one plus 7 pro, and get back to stock with an older oos version in it. From there i can choose OTA upgrade or local upgrade.. Whichever way? Right ?

Yes I used 9.3.4 and then did local update but if you are on 9.3.4 you have to flash first 10.0.3 and then after that 10.3.4 to upgrade.
I am having a big issue. I have a Poco F2 Pro, and I'm changing the firmware to the euro version. For some odd reason I'm on V12.1.3.0.RJKCNXM, Android version of 11. That's the Chinese official firmware I believe.
Don't ask me why. I must have botched the intial set up. Anyway, want to upgrade the to the latest euro firmware/android version and upgrade to a better rom and finally get rid of this mi-bloat. Sadly, it says I need the flash tool and I do have access to it, but it's on a roommates computer and I don't like depending on other people. Is it possible that I can somehow use the TWRP I have to upload the firmware vs using the flash tool? Please let me know thank you!!!

You will need a pc to flash the TWRP.
Flashing a TWRP takes 10 seconds.
With Miflash 10 minutes.
But with the twrp you have to format the data and then put the pc rom on the phone (usb OTG solution).

Thank you. I actually have a TWRP installed called "LR. TEAM" I think it's a Chinese port of TWRP translated back to English. It's called TWRP 3.4.1b-0328.
I can't flash anything from there though, as I can't decrypt the storage and I don't know how to remove encryption.
With that TWRP do you think I might be able to flash the Euro Firmware without Miflash? I have ADB and fastboot via my chromebook. Thanks for all your help.

EEA was specifically designed for EU countries .(RGPD,GDPR).
The EEA ROM doesn't have a Beta program.
Global updates arrive before.
AOSP roms are based on global version.

Background:
I unlocked the bootloader and then proceeded to flash the device from 12 to 11 using THIS tutorial. When I got to the first "fastboot reboot fastboot" the phone never rebooted. The screen is all black. I can't get into recovery or back into fastboot using the button method.
I downloaded the MSM Global tool and got all the drivers installed. I was able to start the flashing process but get "Device not match image" early in the process. I have called OnePlus customer service. They didn't ask any questions just told me to send in the phone. I would rather fix this myself if possible. Any insight and or help is much appreciated.
UPDATE: I found this information, and it had me flash the India 9 Pro version. It worked. I have a booting phone and can now work on getting it back to the US version.
I wish people would stop following the guide for fastboot flashing. Just use the MSM while it still recognizes your device because if fastboot flashing fails, you end up having to flash it multiple times as it's not recognizing it as the correct unit anymore with that level of corruption.
To get back to global firmware, flash this in the local upgrade tool.
https://oxygenos.oneplus.net/OnePlus9Oxygen_22.O.11_OTA_0110_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.
If you download it directly to the phone or copy it over with a PC, the file may disappear. Enable USB debugging and use adb.

Thanks for that! The phone is back to fulling functioning with the proper version of OOS. It has been a long time since I rooted and ROMed. Fastboot used to be a straightforward method of flashing a stock ROM. Doesn't seem like it is anymore.

Glad that it worked. Did you have the bootloader locked? I am just trying to confirm I'm not crazy and that I was actually able to use it with a locked bootloader lol.
Yeah fastboot flashing was the gold standard way to avoid a brick back in the days before A/B partitions and Android Verified Boot came along but not so much now. This device in particular seems to be really fussy about fastboot flashing. I never managed to brick my Pixel 3 XL doing it but I have had to MSM multiple times trying to do fastboot commands and custom recoveries to flash custom ROMs on my OP9. I have got the process down tova science at this point lol. I just went back to stock and rooted it and I'm much happier with that than I was with custom ROMs that were plagued with issues.

Yes, you can use this to go back to OOS11. You shouldn't need to unlock the bootloader as this is an officially sanctioned downgrade package.
Since you're on Android 12 you need to install the local upgrade APK:.
https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk
Install that, push the downgrade zip to /sdcard/, open the newly installed system update app, hit the gear, and it should show you the zip file waiting.

There is a pinned post with them. This is C.48 for global and yes, you use the local upgrade but since you're on OOS11, you don't use the APK, use the update function in system settings and tap the gear and you'll see it.
Hi i tried to use the updater on android12 and try to downgrade it to .48 but it return error. So i need to downgrade to android 11 first and then update it again to .48?

Correct. Only the specific downgrade packages can downgrade. It will also wipe the device. There's no way around this. Once you are back on 11, you can do the local upgrade to flash the full C.48 ROM instead of having to do the whole OTA process (normal process is downgrade, OTA to 11.2.10.10 (it will say it's C.48 but have a file size of like 150MB but it's not), OTA to C.48 so you get to skip a step if you just use the full update package).

Ok if i understand correctly, i just use the updater to flash the android 11 zip file that you provided and it will do a full wipe and will restore to android 11. Then i just use the updater again to flasj it to .48
am i correct?

I don't know because I didn't get my phone until February so I went right to 11.2.10.10. It is important to update though because it gets you a working OS on both slots instead of just one.

Lol yeah. I'm not too happy with C.60 either. I really don't want to wipe my device and lose my Signal chats again.

I don't know what you aren't understanding but I'm tired of repeating myself. Read what I wrote and it answers your question.

Ok done it ... on OOS11 now .... no need to unlock bootloader can just flash the file directly.
Will try OOS11 for a while and see if it is worth updating to OOS12
Hello I converted to KB2003, currently running F63.EU
I've always seem conflicting answers on this subject, but is it possible to change regions from EU to Global doing a local install or flashing in custom recovery without having to wipe data?

I've done it in the past without problems by using local install but don't take my words as certainty. Anyway, always use full builds and always update to a build that has been released after your current one.
I did some TWRP testing (last year using KB2003 C.33 and KB2005 C.33) and found that without doing a data format or factory reset I could flash KB2005 firmware over KB2003 firmware (and vice versa) and the system comes up cleanly.
So, purely from a firmware perspective, the answer to your question is Yes.

So to confirm, this was not an OTA zip that you flashed in TWRP?
Also, did you pull the firmware from payload or use the flashable firmware?

You installed via local install using a full build you got from a Oxygen Updater? Do you happen to rememeber what build and regions you changed? Just wanted to get some more specific info

I actually can't remember the details. I had KB2003 installed on one slot and KB2005 installed on the other. The easiest way for me to do that would have been to use local update to install the full OTA zips (because the full OTA doesn't check what's already installed). But I might also have used TWRP to install the full OTA zips. I just can't remember and I didn't keep notes on the installation method.
And then I could swap between the two slots by simply flashing in fastbootd the non-A/B partitions and the logical partitions (all extracted using payload dumper).
At one point I think I also installed KB2001 (IN). And, I'm presuming, that would also have been using local update.
Note: I've edited my original post - it should have only mentioned KB2003 and KB2005.

Well if you did this while using OOS11 then the results are irrevlevent since we're talking about OOS13
