[OnePlus 6] How to rebrand your device: from HydrogenOS to OxygenOS and vice versa - OnePlus 6 Guides, News, & Discussion

After some months i want to explain how to pass from hydrogenOS to OxygenOS and vice versa.
The first thing you need it's the stock rom, you can find here:
XDA Thread
Official OnePlus site (OxygenOS)
Official HydrogenOS site
You have to make sure that the version you are installing is more recent than the one you have on your mobile phone or the process will stop giving you an error, this is because oneplus has blocked the downgrade of the rom (You can also install the same version of the rom ).
At this moment you need to:
Push the stock rom on your internal storage ( in the main folder )
Go in settings/System/System updates/Setting icon on the top right/Local upgrade
Now you should select the stock rom you want to install and then need to click on "Install now"
You need only to wait the process finish to reboot your phone.
After rebooted you need to restore your phone, you can do it through stock recovery or better from Settings/System/Reset Options/Erase All Data (I suggest you include "Erase internal storage").
Now your phone is officially rebranded.
I made a video to explain how to make this local update:

I have a oneplus 6T
i'm trying to go from HydrogenOS to OxygenOS using the zip i downloaded from OnePlus site. I tried to flash the zip with updater option you have on the phone but it told me that the zip i'm trying to flash is older than phone version installed. i tried to flash it in recovery but i don't have options to do that. Some guys tried to flash it via the download tool but i don't know if the successed. (I didn't unlock bootloader yet)
(ho visto che sei italiano, se hai telegram potresti darmi una mano a cambiare rom da lì, in modo da avere una comunicazione più veloce? sempre se hai voglia)

Yes. The beta worked. Does it still update to the next one or do I have to download the next update manually?

What is the difference? Between the beta and the full version?

Does this work to rebrand from Hos to oos? Thanks.

Hello. I have a question: I downloaded Oxygen OS 10.0.9 from a XDA Developers link and installed it via local update on a brand new OnePlus 7T HD1900 to flash out the Hydrogen OS 10.0.7 (fresh out of the box) . The device took it successfully without the "downgrading is not allowed" error and I did a reboot after (as the phone prompted after each local update). The reboot time is taking forever (running at about 35 minutes now as of this typing), stuck on the OnePlus circling animation. Is this normal? I'm so nervous right now, I might have bricked my wife's surprise birthday gift. Can you please help? Thank you very much in advance!

Stuck on boot screen means boot loop. You've bricked your phone.

Hi , would you please tell me how can I "reboot and install again" ?
Since the touch screen is not working , I restart the phone by pressing the power key a few second . Restart the whole process for more then 10 times but the touch screen is still not working .
ASUS messed up the touch screen by updating the firmware nearly in every version, I suggest you upgrade to the newest ROM and flash twrp again. For reboot just issue ' adb reboot ' ..
May I know your firmware version ?

Hi , thank you for your suggestion .
I can't get the firmware version in the hardware information section , so I bet the software version will work as well ? Actually , I just updated my phone few days ago , so I think I'm already in the latest version .
( maybe this one ? )
After entered the TWRP , no matter ADB or Fastboot has no response , so the only way to reboot is to press the power key for about 10 seconds .

Root and OTA
Hi,
If I used your unofficial bootloader unlock method and install TWRP and root, if I want to get the next asus OTA update, can I unroot and download the full firmware from the ASUS wesbite and install it even though I have the bootloader unlocked? Thanks.
Hi. I want to have root but I want to know how you get OTA or how to get back to stock ?
Sorry , it's me again . Just a few hours ago I roll back to stock system , and perform the OTA update . After that I've root with the system again the system keep going into the recovery and cannot return to android system . Is there anyway I can return to the normal andoird system ? Thank you .

If still on TWRP recovery copy the full ROM (downloaded from ASUS, do not unzip, just copy the zip) to a SD card or to internal memory of the phone, reset to factory from within TWRP and perform an install. Worked for me. First boot takes ages

Well , I've tried this at the very beginning , but no luck . Seems the recovery is corrupted and keep stuck in it .
Finally , got a .img reocvery image , flash it via TWRP and the system resumes normal , at least it is working for me now .
Hello everyone,
I consider an update to the latest 15.0405.1712.83 version, so I'd like to know if there are any issues with TWRP compatibility or getting root back on the new ROM. Any modified boot needed?
Hello everyone,
I installed the twrp on my Asus Zenfone 4 (ZE554K -WW_14.1050.1708.36). I tried to root it, but no success... After several tries, I just gave up and now I'm trying to get the stock recovery. I couldn't find the stock recovery.img on "google" for this model. Is there any way to remove the twrp from this model of phone and some way to get stock recovery.img ? I tried to download the firmwares from official site, but I couldn't find the recovery.img inside zip files.
Thanks in advance.!

I just use the above TWRP, just can use it to install Magisk to get root.
This cannot backup data...
(Therefore suggest just boot off the custom recovery TWRP without installing it until a new version release)

Thanks again for your suggestions.
I was on 14.1060.1709.80 version of ROM with the TWRP 3.1.1 (2017.10.11).
Somehow I've managed to update to the latest 15.0405.1801.89 stock, and then flashed TWRP 3.2.1 from the @shakalaca Medium blog, so the credit goes to him anyway.
Seems like it works just fine, I successfully did a nandroid backup and flashed the latest Magisk version.
P.S.: Unfortunately I can't post external links, so either you find it yourself or the author would post the link in this thread.

Thanks! Good news for about TWRP 3.2.1 !!! :laugh:
Then I searched in Google and found a web site: Android Infotech
then download the TWRP 3.2.1 version and tested,
it can use the sd card and also can read the data!
Therefore it can use to backup!

Sorry for delaying on reply and thank you so much for helping !
Next day, after I posted here, I searched a bit more and found a link with some recovery files.
Unfortunally I can't post the link cause I'm new user, but it's a Stock Recovery from shakalaca, on androidfilehost.com (thanks to him).
Then I got the stock ROM and everything gone ok. Then I updated to Oreo and now I'm trying to troubleshoot an usb file transfer issue. Another long history...
Is it safe to do this? I am with ZE554KL and a week, and I want to do root, but I am afraid and doubt, if someone can tell me if it is safe, I am grateful.
--------------------------
é seguro fazer esse procedimento? estou com o ZE554KL e uma semana, e quero fazer root, mas tenho medo e duvidas, se alguem puder me afirmar se é seguro, fico agradecido.
Any way to un-unlock the phone? I unlocked the phone and never had any luck booting into twrp. Ended up in a boot loop (fixed) so just going to give up on it for now before i brick it. I see no point in leaving it unlocked

It is safe to root the device , however , please make sure ALL your data already backup .
I'm not sure if it is due to the new android file system or not , but my storage is totally wiped out after I root the device . it's not happened for my previous android phone .
Just my 2 cents .

How to go back from Oxygen to Hydrogen?

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.

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. ?

Hi,
No guide needed. I did this many times.
Flash the official global via TWRP if rooted, flash TWRP installer after reboot into TWRP, flash MAGISK, reboot all good.
NOT ROOTED, update via phone update software setting in settings menu(THREE DOT MENU, top right ) find your official downloaded zip and update.
I am not rooted. I tried the phone update software, it says the global version is older than my current EU version. I downloaded the 1.0.0.1 one and i am on EU 1.0.0.1

hi, my OnePlus 7T is not rooted, so when I "update via phone update software setting in settings menu(THREE DOT MENU, top right ) find your official downloaded zip and update"
Will this way wipe my phone`s data? There are more than 100 APPs installed in my phone, so a little worried.

Hi,
Doing an official, update via the software settings on your phone wont erase your data.
You dont have anything to worry about. :good:
Just did an update , this way for a friend. No data loss.

Ha!Thanks for your quick reply, big help to me.

oneplus 7 Pro , trying to update to Android 10

I had a oneplus 6 and that updated to android 10 a while ago.
Now I recieved a oneplus 7 pro. But the problem is it will not update to android 10.
Tried a system update check, Said up to date.
Contacted oneplus they mentioned the local file upgrade
Downloaded that ZIP and tried again, it tells me system update installation failed.
I am rooted and have TWRP installed as well as magisk.
Considered flashing from TWRP, but since it is an official system update not sure how that would work.
Is this my best option or anyone have an idea on why it fails.?
Tried different suggestions, nothing seemed to work. Did not try to delete cache yet.
Hi
Did u try Tool All-in-one? Marvellous tool!

Hi,
you cant update to the latest 10 from 9 ... you need to do it incrementally

You have not provided
any information about your phone:
1.) What version of OxygenOS do you currently have on your phone?
2.) What is your Phone Model?
[GUIDE] OnePlus 7 Pro [Region] (MODEL)
P.S.
From Android 9 to Android 10 (Official Stock ROM)
First with local upgrade go on OxygenOS 10.0.3
After this, upgrade to the latest version of OxygenOS
Local Upgrade
1.) Download the file OxygenOS 10.0.3 Global OnePlus 7 Pro 2.0 GB and copy it to the root of the internal memory
2.) Go to Settings> System> System Updates> Click the gear at the top right> Local Upgrade> Click on the appropriate installation package> Update
3.) After the update is completed, click Restart
4.) The update was successful.
Note If you do not see the firmware file, then check the file extension should be .zip (if you have .zip.jar just rename it by deleting .jar)

Updater didnt work, but ended up booting from local updater after the file was downloaded.
Then I ended up doing local update with the update from oneplus latest.
Now I am working on redoing TWRP. It is sticking on fastboot mode after doing a fastboot boot twrp-3.3.1-4-guacamole.img
Just hope I didnt mess something up when I did the TWRP Magisk A/B retention script.
May try a different TWRP boot img
Newest TWRP worked fine.
ReInstalled Magisk.
All Data and apps are good.
Few minor issues but nothing to serious.
Thanks for all your help !!
