Hydrogen OS 2.5.1 to Oxygen OS 3.5 - OnePlus 3T Questions & Answers

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.

You really dont need to re-lock bootloader. You could have just downloaded and flashed through twrp and then flash supersu. But i am not sure why it is failing on your end.
Same thing here, always installation failed
Try a different type c cable.. Apparently, I was having this issue
Op3t original cable : Android auto and adb side load works perfectly on my op3
But when used on op3t, android auto cannot detect and side load of ota fails.
Used the original cable from Google Nexus 6p, Android auto works perfectly but I didn't try side load adb because I already flash via TWRP instead.
Try changing cables
Found a FIX!
its sort of a long process if anyone is interested lmk sorry would post but doont know if anyone cares

I too had the same problem. Can you explain me how to get that?
sure @kabeeradam so what you need to do or atleast what worked for me was go all stock recovery and rom and had bootloader locked too.
flash the beta rom from oneplus through sideload then flash the stable rom from oneplus then do the normal ota update and it should work. lmk for any other info also sorry if it looks like a mess this is my first time explaining these types of things. hope it helps

Downgrade 4.1.3 to 4.1.1 (and beyond)

Hi all,
I am having issues with my Bluetooth and GSM. I am considering trying to downgrade from OOS 4.1.3 to 4.1.1. I am completely stock, not rooted and don't even have TWRP.
Would appreciate some clarification to the following questions:
1) Can I downgrade by just flashing the official full 4.1.1 zip found in OP website?
2) Should I only flash the modem zip? And if so, can I use 4.1.1 modem while having 4.1.3 installed?
3) Since 4.1.1 already has nougat 7.1.1, is 1) also safe for further downgrades, for example, directly to 4.0.4?
Thanks.
Best regards,
Oldiamond
If your bootloader is locked, you can't downgrade (unless you exploit the security vulnerability from a few weeks back).
If your bootloader is unlocked, use TWRP or fastboot to clean flash whatever version of OOS you want.
You should consider flashing the latest open beta release, I think it's already fixed over there plus there are some Extra goodies and its stable as ****

Thanks to both. I am this close to send it back to RMA, as I did not install anything other than 4.1.3, and didn't even unroot it. I don't know... perhaps by sending it back without ever installing TWRP or unlocking anything would provide more feedback to the manufacturer, other than saying "damn guy, started fiddling with the phone and ROMs, and here's the result".
Regarding the beta, I initially considered avoiding it because i read in the forums about issues such as sometimes alarms not ringing. I figure that my boss wouldn't like that
Going back from BETA to regular version also requires TWRP?
Best regards,
Old

Alarm issues were fixed, also it never happened to me I and I've been on beta a long time i think on the official page there are the steps to switch between stable and beta. I don't think it requires twrp but don't take my word for it.

Oreo stock recovery after switch to TWRP?

Hi guys. I got this device today and am very happy with it.
I'm used to rooting my devices, so I want to root this one too and was hoping you could help me a bit.
I have the Oreo update installed and I see there are some TWRP that work with oreo. What is the best one to use with stock rom? I only want to root so I can install adaway and lucky patcher. Also, if an update comes later this year, like android P or something, can I switch back to the stock recovery, install it and then switch to TWRP again?
So, basically, where can I download stock recovery for Oreo, what TWRP should I use?
Thank you very much

I'll add #geek to the post
I am pretty sure you need TWRP. Here is a good guide: https://forum.xda-developers.com/p10-plus/development/magisk-p10-p10plus-t3752482
I do not know how to update with root. I am afraid it involves reinstalling the original recovery and a factory reset.
Unlocking the bootloader is currently a bit of a hassle since the unlock webpage is down. You'll have to contact Huawei Customer Service to get the code.

Good low effort way of keeping a rooted stock Mi 9T Pro up to date?

Hello,
I bought a 9T Pro in Europe for my wife and until it arrives I'm trying to research and come up with a low effort process of keeping the stock ROM up to date and rooted for her. I'm confident in manually installing and updating custom ROMs, rooting and dealing with custom ROM issues, but she is not. Therefore I thought the best thing is to use the stock ROM - not custom - since it may be the most stable experience and for me to update and re-root it for her regularly. root is mandatory because we need AdAway and other things. As I understand it, as soon as we unlock and root the phone, OTA updates for stock are impossible and maybe even dangerous. I've tried researching here but am bit struggling to come up with the right infos and I'd be glad for any advice.
Of course I have seen the great thread about unlocking, rooting, etc, but It seems that that deals with non-standard Chinese firmware pre-installed, which is probably not the case on our device. Since it's bought in Europe, I think it will probably come with some Global or EU ROM. And it doesn't answer some of my other questions.
So far my idea is roughly like this:
Phone arrives
Immediately update it via built-in OTA to latest official stock ROM
Unlock, install TWRP, root with Magisk
Use the phone
Whenever a new stock ROM comes out, download it from XDA
Flash new ROM in TWRP and root again with Magisk
Repeat 4-6 as new stock ROM versions are released
Of course regularly backup with Titanium Backup and TWRP
First of all, would this work or did I misunderstand something fundamental?
How does low level firmware / modem update come into play? Would that be included in the stock ROM packages I find here? Or do I need to manually update that separately? How do I know when I have to, since there is no custom ROM maintainer telling me when it's needed?
Is there an easier way of doing this? This process requires me to regularly check for a new stock ROM, then borrow the phone from the wife for some time to backup, update, re-root and so on. Not that convenient but it would work if there is no better way.
Sorry for the long post, but I'd be very thankful for any advice or ideas. I did quite some research, but if all this info is already available and I missed it, my sincere apologies. It's a lot of info about a new device to take in. :silly:

I didn't keep stock MIUI long enough to know definite answers, but from what I remember, this is my understanding.
OTA will still work and shouldn't cause any issues, just that you will lose TWRP and root whenever you do this.
The steps you give are the normal way to update with TWRP and root.
However, OrangeFox recovery (a heavily modified version of TWRP) is often used instead of TWRP in this circumstance. It is built specifically for MIUI devices and with a little bit of work, I believe that it is able to survive OTA updates. Have another dig around for OrangeFox in this forum section and hopefully you'll find details on how to set it up so that you can still take OTA updates.
Edit:
Found this guide https://forum.xda-developers.com/k2...efox-recovery-mi-9t-pro-t3980579/post80480669
It seems OrangeFox it's a bit hit and miss.
Also Xiaomi.eu ROMs are another alternative to look into.

Wow, that's a lot of helpful info, thanks a lot for pointing me into these directions. I will definitely look into Xiaomi.eu, I that sounds promising!
Get phone. Apply for unlock. Unlock.
You can use my guide bit.do/raphaelguide
Use orangefox 10.8 use magisk.
You can flash eu ROM. Stable version. From xiaomi.eu
Eu rom installs official twrp after install. You are familiar with that
Once you have eu ROM ( same as stock, better performance, minimal bloat, no ads, no tracking)
Eu ROMs gets OTA, keeps root. This is exactly what you want. Just press update in settings as normal ota. It'll do normal ota update by itself, no titanium, migrate hassle.

Question Miui 14 root

Is there already a way to root on android 13 for redmi note 10 pro? Twrp? I can't find anything so far, maybe someone knows something?

Same as on Android 12. That was the one with the issue decrypting in custom recovery.

Yep.
so, i bought my new redmi note 10 pro yesterday.
its on android 12, miui 13. and it asks me to upgrade.
i havent upgraded yet, thinking maybe rooting it with twrp and all, would be difficult.
Should i keep the current version and root it. or am i ok to upgrade it and then rooting it?
seeing this thread, it seems like im ok with upgrading and rooting. but want to make sure.

Wait the days until you are unlocked, in case something borks during that procedure.
thank you for replying.
well, i couldn't wait, considering the new update is lighter and better. so i just updated it and everything went smooth. What is the best way of rooting it? i mean, should i go with or without the twrp. any bugs with the twrp. or is there any better recovery to flash.

I'd just fix boot.img with Magisk to root. TWRP is mostly just for flashing different roms, and our phones use 2 different touch screens, so your might not even work in TWRT.

I have been using TWRP on every device i have rooted. i just love the TWRP recovery. because, as you said, it allows me to flash different kind of roms and it allows me to backup my current rom.
i am probably not going to flash any custom roms on this device, but i would like to have the opportunity to backup my current rom for flashing it later on if needed.
Will i be able to do this with the fixed boot.img and Magisk?

Magisk is just for root and different modules (like viper4android). You need TWRP to backup rom, but as I said touch might not work for you, check the TWRP touch not working posts.

well, it seems "not worth it". until an official TWRP is released.
And if i decide flash boot.img/Magisk or TWRP, mtk will restore my device back to its locked/stocked state?
