Oneplus TWO A2003: convert OxygenOS 3 Beta to HydrogenOS (ALL STOCK) - OnePlus 2 Q&A, Help & Troubleshooting

Hi guys,
my Oneplus TWO is totally stock (no ROOT, nor Recovery, locked bootloader).
I just want to ask how could I "convert" it to original HydrogenOS, with working OTA feature.
Is there any procedure to follow?Is it possible or I need to unlock IT and flash a custom HydrogenOS firmware?
Edit:
Fist unlock the booloader, easy step.
Download specific OxygenOS 3.0 TWPR and SuperSU available here:
- [ROM][OTA][Oxygen OS] Mirrors for official Oxygen OS ROMs and OTA updates
Install Recovery and SuperSU.
So now you are able to flash any firmware.

Thanks for your reply.
So, I just need to unlock my phone, install TWRP compatible with MM (link) and follow instruction for HydrogenOS.
But, as I understood, OTA is not available.

If you don't flash the Debloater+SuperSU zip you may get OTAs but you won't have root and you'll have a pile of Chinese apps.
I don't really get why OTA updates are so important anyway.

If you are in H2OS and that there is an update you will need to flash the full rom(if you are root) it's recommended to clean flash if you flash a full rom but you can use titanium backup otherwise i think dirty flash full rom will be fine

Hi, mission completed!
I've unlocked bootloader.
I used specific OxygenOS 3.0 TWPR and SuperSU available here:
- [ROM][OTA][Oxygen OS] Mirrors for official Oxygen OS ROMs and OTA updates
So I was able to flash HydrogenOS!
Thanks guys.

Is it possible to build a pre-rooed stock ROM?

I have a ZE550KL still stock and don't want to root it until I can find a way to build a pre-rooted stock ROM so I can keep root but also update or downgrade versions as I like.
I also have a Sony Z3 and a Samsung S3 and both are quite easy to build pre-rooted stock ROMs, especially the Sony with PRFCreator. Now we have the TWRP recovery, flashable SuperSU zip and stock ROMs, is there any way to create a flashable pre-rooted stock ROM?
you may use pre rooted patched firmware
http://forum.xda-developers.com/zen...oot-ze550kl-zenfone-laser-z00ld-1-15-t3249326
you do not need to unlock your phone.
just follow instructions, latest firmware is in same link.
you may download any version you wish.

Yes I know I can flash your patched firmware but I was hoping that after the initial root that I want to be able to create my own pre-rooted stock firmware. At present I always have to wait until you post an updated patched firmware.

Flashing Nougat with TWRP without losing TWRP

Hi, newbie question here. I just got my Axon 7. Unlocked the bootloader. Installed TWRP. Made full nandroids of stock and rooted firmwares.
I would like to flash the new Nougat update. What would be the best way to accomplish this without losing TWRP? and what is the correct firmware to use? ota? Also can nougat be rooted? Just dont want to brick my new phone. Thanks
No TWRP flashable file yet.....but I'm sure it'll be soon.
You will need to be on the Nougat bootstack, but you'll have to search for that info.

How to revert rooted XT1572 on Nougat to unrooted stock rom

Hi,
I am looking for a way to revert my rooted XT1572 to unrooted state.
I guess I just need to flash a stock rom. But I have the impression there are no stock roms released for the XT1572.
Flashing to stock marshmallow and next upgrading via OTA to nougat might have been a solution. But I read several messages that downgrading to MM and next updating via OTA will brick the phone?
Seems to me that I am stuck with my current rom? Or is possible to flash an XT1575 stock rom on a XT1572? (I don't care about future OTOA's). I am just trying to revert it to a little more 'default status' before selling the device.
Some added info:
Currently my build number says:
NPHS25.200-15-3
Googling this number directed me to following page:
http://guofeng.io/moto-x-style-7-0-xt1572_clark_retla_ds_7-0_nphs25-200-15-3-official-package-root/
There I find following file:
XT1572_CLARK_RETLA_DS_7.0_NPHS25.200-15-3_cid12_subsidy-DEFAULT_CFC.xml.zip
Would it be reliable to flash this to my device? Or should I also pay attention to other things?

Only for:
Latin America, Dual Sim.
Do you have twrp?
Magisk? SuperSu? Stock Twrp's backup?
You cannot take the Nougat update once you go back to MM. It will hard brick your phone. You kind of have to be on the same security path from what I read. Google has started to not let you downgrade do to security reasons. Sorry I have a MXPure but it almost identical as how to.....except for firmware. To unroot the phone completely you need the stock firmware associated with the phone or a stock unrooted TWRP.img.

Have TWRP, Magisk but stock backup (shame on me).
I wouldn't if the stock rom is from a different region but I guess a stock rom for dual sim will not work on a device with only one sim.
Would it be an option to use someone else TWRP backup?
If you didn't modify system partition - simply unroot with magisk manager app & format data/f.reset with twrp.
Stock recovery - you should ask here(or another thread) - maybe someone will upload it(can done with flashfire app).
I didn't see any backup for xt1572(Nougat). @blondie99
Thanks

Bootloader and modem question

How do I know which bootloader do I have? I'm currently running build B35.
Can someone direct me to a thread how to flash universal bootloader and modem?
If I use bkores flash toolkit, it said you have to flash universal bootloader, modem along with Rom and Gapps but in which order?
If using twrp for future flash do I need to flash universal bootloader and modem every time I switch ROM?
I'm not an expert but here's what I understand.
1. You don't have to worry which version you have unless you're flashing a custom ROM, usually for Nougat you want the B15 and for Oreo you want the B35.
2.Universal Bootloader>Modem>ROM>GApps>Magisk/SuperSU
3.You only need to flash it once if you're switching ROMs with the same android version.

If you haven't you need to unlock your bootloader before you can start flashing custom ROM. You can find a guide on how to do it here.

Install GLOBAL firmware after root and unlock bootloader

Hello everyone.
I will give my wife my grade 7.
My redmi note 7 is rooted with magisk and twrp installed.
I would like to leave him a clean phone, without custom ROMs etc ... and with a recovery stock.
I would like to flash him a Global ROM from MIUI.
For that :
1 / Do I use Miflash to install a global firmware?
2 / Is it better to check the box relock bootloader? I read that this could lead to some hard brick xiaomi ?
thank's for your answer
Miflash? Why not.
Looked? Why
Unlocked. Maybe u can fix it!
Stock? Why?
Batterylfe?
Adaption?
Hello
Quick question about using a Firwmare MIUI stock version and OTA updates.
Can OTA updates be done automatically if the bootloader is unblocked (no root / stock recovery) ?
Thank you in advance.
