OxygenOs 4.0.2 on Chinese One Plus 3t with HydrogenOs - OnePlus 3T Questions & Answers

Greetings from the Netherlands,
I have just got a new One Plus 3t from China as a Chinese New year's gift. However, it has HydrogenOs on it, which I can not really benefit from in the Netherlands (Since there are no Google apps on it)
I have read somewhere, that I am able to flash OxygenOs version 4.0.2 on the device, without unlocking the bootloader, a custom recovery and having to root the phone. I read that I should be able to just directly download the OxygenOs zip file from the OnePlus website and I could just copy the zipped file into the phone storage, and boot the phone from the internal storage.
Can someone tell me if this is true? Or should I do something else? Let me know!
Thanks a lot,

Im with that ver of 3t (a3010) shiping with h2os..
Dont need to unlock bootloader ..
Download OxygenOS 402 official
Update trough internal or sideload it.. Don forger to wipe user data before and after...

Greetings from China.
I am Chinese and I bought OP3T with HOS. Unlocked and flashed TWRP and Oxygen 4.0.2 just for Google service.

Question OTA Updates with bootloader unlocked

Hello,
as the titel mentiones, does the phone get OTA updates, stock Rom on it, if the bootloader is unlocked?
It does yes
Thank you
I will receive my Mi 11 (Cloud White) 8/256 next week, come from a OnePlus 8T (DL Unlocked & Magisk)
On OnePlus when an OTA was installed, for keep Magisk, after OTA installed and BEFORE restart phone, we reinstall Magisk with the Install > install in inactive slot/space (special after OTA) because Oneplus 8T use A/B partitions.
My question is simple, it's the same thing on the Mi 11 ? Useful for update officialy without lose Root or without need to reflash the patch boot/magisk

Question Decrypted stock firmware - Global

Hello, dear fellow 8i-Users!
I got this device just a few days ago. It is running on A32 global firmware and wasn't offered an OTA update.
So far, I have unlocked, rooted and installed TWRP, following the guide provided here.
As I like my phones to be encrypted, I guess I will stay with stock firmware so far. I'm finding it a bit sad though that I wasn't offered an OTA update and therefore am stuck with security patches dated back to November 2021.
Therefore my question: Does anyone happen to have decrypted versions of a newer version of global firmware? And if so: Is it possible to dirty flash these in TWRP?
Thank you!
Cheers,
VV

I doubt it will be possible to flash full ROM through TWRP unless you prepare extra files (like scripts which do the actual work).
Anyway you can decrypt the official firmware (the ones in OFP-format) by youself and flash it with SPFlashTool.
Here are few hints for you:
Download the version you like from here.
Decrypt it with oppo_decrypt
Merge super.img for the region you need (refer to super_map.csv to find out which parts need to be merged; refer to this comment for instructions)
Flash with SPFlashTool in Download Only mode (refer to this guide)

Question [NE2211] Indian variant OTA & ROOT ?

Can someone suggest me how to update and keep ROOT? There's no Full OTA for NE2211 A17/A18 still. I'm currently on A.15(rooted) which is quite old.
Glad if someone share Full OTA links for NE2211 variant.

I can't take risk of ending up in bootloop. I have already visited service center once for flashing.
I do not think there are full OTAs anymore for many regions besides NE2213. It's fine though, you can update with the OTA incremental as long as you unroot via Magisk image restore first, reboot, then take the update.
You can then download the NE2213 variant of your firmware version, rip the boot.img out of it with FBE, patch it with your own Magisk installation, reboot to bootloader, BOOT that patched boot image you just made, and from there do a Direct install ON the device.
NEVER Flash from ADB with this device. 9 times out of 10 you'll regret it.

The latest OTA A18 for NE2211 has Jio 5G support. Switching region, I might lose me those updates.
You do not switch region, lmao. At no point did I say to flash a different region.
You update your local NE2211, then take the same version of that like A.17 or whatever, the full ROM from NE2213 and you only need to extract the boot image from it.
You never flash these files. Lol.
There's no A17/A18 for NE2213 i guess so no chance.
Looking into it a bit, yeah, it seems the A.18 is India exclusive so you're a bit SoL there, unfortunately. There is a way to extract the boot image from an incremental but I'm not versed in the method.
If you don't mind Android 13 there is the current C.21 for India variant, it also says the Jio 5G support. You could use Oxygen Updater to grab the Full Upgrade Zip for that version, then root again like from stock.

Question NE2213 to NE2215

I have the US version of the 10 pro, but I recently installed the NE2213 rom with the latest security update - c.26. My bootloader is unlocked and I am rooted. What is the best way for me to get back to the NE2215 rom? I can't find a full zip of the NE2215 c.26, and I wasn't able to install the NE2215 c.22 using oxygen updater. I do have twrp and I have the NE2215 c.22 rom saved, so is it an option to flash that rom in twrp? Any help or advice is greatly appreciated. Thank you.
You sort of screwed yourself by jumping regions for now, you'll have to wait for a full ROM of NE2215 to be released if you don't want to lose Data. If you're fine wiping, you can use the rollback package to NE2215 A12, then update all the way back to C26 2215, and then root there.
Using the OTA method worked for me, for the record, for updating from C22 to C26 with NE2215. Unroot, take OTA downloaded from Oxygen Updater in LocalUpdate.apk, root to other boot slot, reboot. The only time this gave me issues is a major Android version switch. (The A12 to A13.) Texts were buggy at first but placing a few calls fixed all that.

Thank you! I wasn't worried about wiping, so I did the rollback and it worked perfectly.
