Hydrogen OS 2.5.1 to Oxygen OS 3.5

Hi everyone,
I literally just got the Chinese version of the oneplus 3T (A3010) and I want to move from Hydrogen OS 2.5.1 to Oxygen OS 3.5 official with OTA. Does anyone have the file or instructions how to do this? I found instructions for the oneplus 3 but not sure with this model. I'm sure any help would help out a lot of people who are gonna ask this question.
Also will this unlock the bootloader? Just curious about it affecting android pay.
Thank you!:laugh:

Wanna do me a favor and grab a nandroid backup of your rom before you kill it? I actually want h2os
Aside from that, you should theoretically be able to: ("Official" guide https://forums.oneplus.net/threads/...oid-efs-backup-and-more.475142/#post-15431571)
Unlock the bootloader
Flash TWRP
Flash dm-verity
Flash OOS 3.5.3 from the ROM page, I have a mirror too (http://forum.xda-developers.com/oneplus-3t/how-to/zip-flashable-firmware-modem-t3509015) mirror on pg 2.
and you'll be set, you can flash the original recovery if it's available on the OnePlus page as well and relock to go back to full stock just English version
PS: Since there is no stock recovery image available yet, maybe will have to run TWRP temporarily, rip the recovery off and then proceed? I dunno

Thanks for your quick reply! I was hoping more along the lines of the adb Sideload method and keep the bootloader locked for now though. If I go the root method sure I can share the nandroid backup.
PS the rom looks really similar to the oxygen rom, so far it looks like only the launcher is different. I guess this is part of the plan to merge the two.

Well you can try flashing the image straight. It's a stock image anyways so it could work.

Basically what I meant was to do the opposite of what is suggested here http://forum.xda-developers.com/oneplus-3t/how-to/rom-h2os-2-5-oneplus-3t-released-t3511443 but with the 3.5.3 ROM

Help needed with android pay and OOS clean install
I'm in a similar situation with a chinese bought OnePlus 3G from Lazada.sg that came with Hydrogen OS. I've managed to install TWRP but because I'm completely new, got stuck and instead managed to install OOS 3.5 (now 4.## from the official website) using adb sideload.
I do have 2 questions:
1) My internet connection drops occasionally even though my WiFi is still connected, is that an issue because I might not have installed it correctly? Would a clean flash solve it?
2) I understand android pay is disabled when you unlock bootloader but even after that, will it be possible to wipe the phone clean and do a fresh install of the lastest OOS and the phone will pretty much be like the international version, with android pay re-enabled?
I believe you can use Sultanxda's patch as another way around, but it sounds complicated as hell for a new person, so I'll continue digging around while waiting for a reply.
Thank you, and any advice will be greatly appreciated.

New and failing!

Hello.
I bought my OP3T and I just got it today. As soon as I connected it to WiFi, the Nougat OTA update appeared and I proceeded to download it, reboot and install it, but the installation just failed in the middle of the process!
Now the phone won't go beyond the boot screen.
Of course, OnePlus support is useless. They can only offer a remote session (lol) or a replacement request. This is what they told me:
"And please do not update your phone to Android N since it's having a lot of issues however, the ROM team is already working in progress to have everything fixed."
I know what to do (I think), I just need little help here with the steps to fix it.
Thank you in advance!
Edit: managed to fix it following the official guide to upgrade:
http://downloads.oneplus.net/oneplus-3t/oneplus_3t_oxygenos_3.5.3/
Now the question is: is the Nougat rom failing for everyone? it seems that yes, according to what I've found in my research...
And, do you recommend to wait until we have a stable reliable Nougat version?

I have not had any issues other than my volume not sounding right. It sounds on low when On medium. I compared it to next to my s7 edge and it is lower when on low but HIGH on max, sounds confusing I know. Other than that I am good battery life has been phenomenal. Haven't done a recommended factory reset just yet though

[SOLVED] Phone changed the model in TWRP

Hey,
I have question about a problem I have.
So I tried to install the latest open beta version (beta 17) on my OnePlus 3T through TWRP.
This didn't worked because of ERROR: 7.
I found some solutions to fix ERROR 7 but it doesn't worked with this OS.
I tried some things like updating TWRP and installing the Oxygen recovery. I messed some things up. I deleted my OS from my device accidentally.
I solved the problem and was able to install the latest stable OS without problems.
Then I tried to install ResurrectionRemix-N for OP3T and I got the ERROR 7 again. but it said:
E3004: This package is for device: OnePlus3T, oneplus3t; this device is Oneplus3.
The thing is, it is an OnePlus 3T.
I don't know why and how it changed. The TWRP is for OP3T.
In the settings it says that the Build-Number is: ONEPLUS A3003_28_171012.
So I don't know. The default device name was OnePlus 3T.
Later I got an automatic email from Google because I logged in on an "new" device. But here they say that it is an OP3.
I would like to change it, but I don't know how.
I thought I can just change someting in the build.prop, but I didn't tried it yet.
Hopefully someone can help me.
-Fun4Jan

Okay so, I went in the build.prop and this is what I found:
ro.build.product=OnePlus3
ro.build.user=OnePlus
ro.build.flavor=OnePlus3-user
ro.build.description=OnePlus3-user 7.1.1 NMF26F 136 dev-keys
ro.common.soft=OnePlus3
ro.display.series=OnePlus 3T
ro.build.oemfingerprint=7.1.1/NMF26F/10122113:user/release-keys
[...]
ro.build.ota.versionname=OnePlus3TOxygen_28_1710122300
ro.build.version.ota=OnePlus3TOxygen_28.A.57_GLO_057_1710122300
So do you think I can just change it in the build.prop?

Yes, you can change it in the build.prop.
please try changing it and report us back.

So I changed it and tried to install it but failed. It tells me that it is an OP3

Try the Qualcomm MSM Tool and try resetting your device completely as instructed on the Unbrick guide. Looks like you installed a corrupted Open Beta package, and something from Bootloader configuration went completely haywire. You can backup your Internal Storage since you have TWRP access.
Good Luck!

Have you tried using TWRP version 3.1.1-0?

So I tried it with this instruction: http://www.androidbrick.com/oneplus-one-two-3-3t-5-mega-unbrick-guide-twrp-flashing/
I did it like it says but some things were different and I think it was because my phone worked and wasn't bricked.
Now I have my phone and got the oldest OOS 3.5.1. My changeable Phonename is OnePlus 3T but I got a mail again where it says that I logged in with a OnePlus 3.
I will try to install TWRP and the latest OOS version.

So I finally solved it.
I was a bit confused with the TWRP version, so I thought that I can install the latest OOS with the Oxygen Recovery and I saw, that I used the wrong Recovery for my phone.
I used the right TWRP version for my phone but not the right Oxygen Recovery when I tried it with it.
I thank all you guys for the help.

No problem, would you mind adding [SOLVED] to the title, so other users with the same or similar problem will read this post to fix their devices too?
Thanks, and happy flashing!

Then try with the older version, the newest one is known to cause problems with proper device detection.
Edit: nevermind, just saw it's fixed.

On my 3T Custom ROM works fine but OOS does not...!

My OnePlus 3T had dive in sea water few days ago. While EVERYTHING seems to work fine on a custom ROM (Can not flash OOS for some reason as it gets stuck at bootscreen) now only WiFi+BT does not work I guess the water must have done something to it not working as a result.
1. OOS flashes correctly but gets stuck in bootloop and vibrates again to get back in a loop of same process can anybody explain why custom ROM is working fine but OxygenOS is not at all????
I have tried Lineage and Paranoid (which is currently in use)... But all OOS versions fail to boot...!
2. Also can anybody please tell me what will be the cost of replacing wifi part for OnePlus 3T in India ?

Have you tried using the Qualcomm factory restore tool to restore phone to OxygenOS? Just make sure to pick the correct one for your phone as the 3 version softbricks the 3t and vice versa.

Need help, stuck in fastboot?

Hey all, so yesterday i got my phone stuck in a "boot loop". I was trying to install TWRP and magisk to root my phone, after 2 hours of constantly reinstalling TWRP i finally got it to work. Every time my phone would end up just being on a black screen not being able to get to the TWRP menu but i could still access fastboot, i fixed it by "installing" orangefox TWRP, it never actually installed it but i got back into my phone at least, however now thats not working, and im stuck here only being able to get into fast boot. I followed this tutorial - https://forum.xda-developers.com/k20-pro/how-to/guide-redmi-k20-pro-unlock-root-t3974127. When i eventually did get it to install TWRP its because i used the All in one tool. Im currently stuck in the loop again, all i did was follow a youtube video on overclocking my display to 81hz, so i was in TWRP, made a backup of a file, flashed the 81hz.img and now i cant get into twrp or my phone.....How do i fix this?
Im currently flashing a stock rom with MiFlash, taking a few minutes but this is the last thing i can think of to fix this, no im not using the flash and lock method.
Edit: So i decided to use the All in one tool to flash the rom instead, i can now get into TWRP but the phone still by default boots to Fastboot, it wont actually go into the phone? What do i do?
Edit 2: Okay so that fixed it, now to reinstall TWRP with the all in one tool and reroot my phone.........
Edit 3: Okay so new issue, everything is all good TWRP is installed phone is rooted, but im trying to update to the latest MIUI 10 version (on MIUI 9 atm) and i can't install it? It downloads fine but it wont install? Do i have to flash the update file since it wont update through the updater?

A bit of advice.
If you don't know what your doing, don't follow random YouTube videos.
There are some very good videos and some very bad videos. If you don't know what you're doing, you won't know the difference between a good video and a bad one
Until you're comfortable with flashing mods, etc. stick to advice given here. It might not be instant, but you'll get good advice (if it's not good advice then someone else will point that out).
When asking for help give us more info.
What phone do you have?
What ROM was on the phone before first trying to install TWRP?
What version of TWRP have you been trying to install?
Why did you change from using Mi Flash Tool to the all in one tool?
Did you wait for the Mi Flash Tool to finish but it didn't work, or did you get bored of waiting for it to complete and cancelled it?
I appreciate this is a bit late now and not necessary as you've eventually sorted it yourself, but giving the info I've pointed out, at the time, may have actually got you some useful replies before you actually got there yourself.

I have a rough idea on what im doing i've done all this stuff before loads, but xiaomi just seems to be different idk. Considering this is the k20/k20pro section i assumed its obvious thats what i was using.......Everything is sorted like i said but i cant get MIUI to update, it downloads, i hit reboot and it boots me to TWRP instead of installing the update.......i've come to really like the MIUI without the app drawer but now i have an app drawer as im on Android 9, I flashed the lastest rom but before flashing i didnt have an app drawer and was on the latest build so no idea whats going on there......guess i just have to live with this now?

What's not obvious is whether you have a Chinese or Indian K20 Pro, or a global or European 9T Pro. Also whether you're trying to install the version of MIUI that is correct for the phone, or if you're flashing from a different region. As you say Xiaomi does things a bit different, so we're seeing things in these forums that what works on one version of the phone doesn't quite work on another.

well heres the weird thing, i bought the EU version of the phone, which i know is supposed to be the 9t pro, but not only did the site call it the K20 pro, but in the settings its model number is also the K20 pro. I got everything working fine.
