{GIUDE} HYDROGEN OS 3.0 [Oneplus 3/3T] Installation/ Quick guide

An update to the H2OS out after a long time. The alternative ROM for the OnePlus devices is now updated to the version 3.0. The Hydrogen OS is mostly designed for the Chinese variants of the Oneplus devices. However, the H2OS 3.0 can also be installed on a regular or international variant of the OnePlus 3 and the OnePlus 3T. The ROM brings many new features.
As the Hydrogen OS is a firmware for the Chinese variant, it doesn’t come with the Google Apps pre-installed. You will need to install it separately. Fortunately, we already have a Google play store installed APK which can easily install the Google Play Services onto your Android device.

Will all the US bands be enabled with Hydrogen OS?
Hi, can anyone using a US OnePlus 3T confirm whether the US version of OnePlus 3T with Hydrogen OS will have the exact same bands enabled as the US version using Oxygen OS? I want to be as Google-free as possible and starting with a manufacturer-supported Google-free ROM like H2OS sounds like a good way to go.
I'm open to other ways to accomplish this but simpler is better for me. Finally moving away from Windows Phone, and yes I know, why would you want Android if you don't want Google? Answer, pathetically trying to cling to ownership of my personal data and can't afford the next best OEM privacy option, the iPhone (which isn't a great privacy option either). Thx!

I've been down this path too many times. It's doable but not easy. First, scrap H2OS since Playstore is preinstalled. I'd go with either a lineage based Rom or Freedom OS (OOS with the option to leave all google and OP Apps out on Installation). Just don't flash Gapps after the Rom.
But thats really the easy part. The hard part is the setup. First, you'd need to sideload at least a browser. Get the browser apk of your choice from a reputable source (xda labs is great. It even manages Updates for you). Depending on the apps you need, you'll need some playstore alternative. Some things can be had through xda-labs. If Open Source is your thing, f-droid is great too. Just don't download apk's from somewhere on the web. Your privacy might be more at risk than with google on it.
Also, get a vcard backup of your contacts (or run your own carddav server). Finally, some apps simply won't run without google framework (that's why it's back on my phone). For example "Bring", a shopping list, won't run without google framework. Don't ask me why. But i need that app. Just be prepared for some major inconveniences, and having to find workarounds... :good:

Thanks for the great input domsch1988. You've given me exactly the tips I need to get started. One question though. You mentioned Playstore is preinstalled on H2OS. I was under the impression the main difference between H2OS and OOS was H2OS's removal of all Google specific stuff to meet China's Google restrictions. I assumed that included Playstore. Are you sure it's in there? I only ask because I'd rather start with a OnePlus supported ROM if I can but if that's not the case I'll take the leap and go with one of the ROMs you suggest. Can you recommend a lineage-based ROM I can start with? And, do you have an opinion on microG as a Play framework replacement? It seems like a good idea in theory but the way it's implemented gives me some security concerns.

OP stated that PlayStore APK is preinstalled. I have not tried h2os, so can't say for sure. You could give it a try. And with root you can always uninstall system apps.
I never tried microg myself. For me it was always no g at all or the pico Gapps package.
As a lineage based ROM, on my note 4 resurrection remix was great. On the 3t I'm on stock oos, so not sure.

Play store or anything Google is not installed on H2OS
i am using it currently tried to go without play store and other apps for one day but couldn't deal with all the Chinese apps so, installed OOS although everything could have been installed on H2OS also.

Ok

Open Beta Not Flashing ( Vendor Partition Problem )

I have Oneplus 5, I was initially running Open Beta 14, I installed Mokee ROM for Android P and later again flashed OP5 to OxygenOS 5.1.3 Android 8.1 using Qualcom MSM Tool.
But I am not able to Flash Open Beta(s) now,, I tried Open beta 13 and 15, none worked.
I clean wiped using stock recovery, didnot work.
Wiped using TWRP by BluSparx 3.2.3 - vendor still not mounted( as it doesnot exists) and - still Open Beta not flashed after wipe.
I also switched to Android 7.1.1 and tried installing Open Beta 13 and 15 - still didnot work.
Please help me switch to Open Beta ROM for Oxygen OS Oneplus 5

First flash open beta 12 then you can flash ob 14 or 15.
Sent from my OnePlus 5 using XDA Labs

Any solution to this problem

Have you read the post above yours? It's mandatory to update to a special ob first so vendor partition will be created.

It's not made clear in the installation notes for OB14, 15, 16 etc but yes as @bkma says, you need to flash OB 12 first if you are coming from non-OB.

The problem is that oneplus did not implement clean flashing of every beta/stable. The updates are always seamless ota updates, hence its not possible for normal users to skip updates and continue with ob16 when coming from OB11 for example.
That's a thing people don't understand here. The process provided by oneplus is fool proof, but when you did not follow the official way, it can be hard, as always.
Therefore its not mentioned in later open beta changelogs or installation instructions. It was mentioned when vendor partition came up.

I see where you are coming from, and you're right, if you were on the Open Beta program all along, this is fool proof.
I bought a new OnePlus 5 about a month ago, I think OB14 was the latest beta release about then. I had not been messing around with rooting, 3rd party roms, kernels, twrp, anything like that. I was just looking for OnePlus official way to get on to the latest beta. It took me a bit of searching through old forum posts (posts which were made before the time I was even thinking of getting a OP5) to find out how to do it.
The information on the OnePlus website currently is insufficient for new beta users to install it from stable. (unless if you go digging through the old release notes) It's not a complaint, just pointing out that it is a subtlety of going to the latest OB that people would have to be aware of if they are new to the OP5 (or if they have recently decided to move from stable to beta).

Any 8.1 Oreo Roms with updates and vendor image question

I was basically wondering if yall could put me onto roms which are 8.1 oreo based but which are still updated regularly for example like the Lineage OS 15.1 roms. Also I had a question about vendor images, from what I understand these are where the security updates and that stuff is stored, would it be possible to somehow use different vendor images with more recent updates on older roms which come with older versions, would it be possible to restore a newer vendor image using TWRP recovery or something like that on an older rom?
Thanks yall.

Security updates are not stored on the vendor. If that was the case even los wouldn't be able to apply security updates then, AFAIK they are kernel based. The only 8.1 ROM still being up date is los which you already know.

Oh I see that makes sense. I guess back porting security fixes to older ROMs is a lot of hard work then I won't even bother.

I've never even heard of anyone trying this. You wouldn't "back port security updates" you would take the most current ROM source and make a new build. When los stops making upstream changes to a ROM you wouldn't even be able to do that. You would have to take their old source and merge the security updates in yourself, since they don't any more, then make a build and hope there's no build errors for you to fix.

Android 12.1 ROM comparisons.

I have the unofficial LOS 19.1 currently installed. Other than the lack of TWRP, I'm satisfied with it. But I see there are two other options available. official and crDroid. Is there any reason I should switch to one of those two? Are there differences in the recovery versions? If TWRP was available, I'd just make a backup of my current ROM and give the other two a try. But as it stands, getting back to my working current version isn't that simple.

Why do you have unofficial?

Because it came out first and I haven't been given a sound reason to switch. Why fix what ain't broken?

I like to use the official version. They provide weekly firmware updates.

To each his own. Personally, I don't care about weekly updates. Unless an update fixes something that I use, or it includes a major security update, I don't care about it. Manually updating every couple of months does it for me.

I am also in unofficial build for now but the official thing is making me wanna try it...but should we just flash it and format data or should be flash recovery provided too?

I would follow LineageOS guide. You will use something other than TWRP. You then use one of LineageOS. This one is quite limited but looks nice (not very important). But I don't need all the features of TWRP, I don't understand it anyway. LOL

How to I get to a specific Oneplus 6T OS? (10.3.11)

I have multiple oneplus 6ts on Android 9.0.13, I would like to upgrade them specifically to 10.3.11. How can I do this? The built in system updates skips over that so I'm not sure.
Also, does it matter if I have the Tmobile device or not?
