Question Need to unroot Nord 2, relock bootloader / bring back stock - OnePlus Nord 2 5G

Hi there!
I would consider my skills of modding as an advanced user, but no more than that. Therefore I need some help. I have a Nord 2, Stock A11 (I believe still version 16), never updated since), TWRP 3.5 installed, rooted with Magisk. Now, the phone became obsolete so it needs to be sold. Therefore I'd need to unroot, re-flash stock recovery, factory reset and re-lock (after that update to A12).
Honestly, I have no idea where to start or what to do. Rooting was such a pain (stock) with several bricks al leading to drive to an OnePlus-servicepoint to re-flash stock firmware - THEN wipe all in recovery and THEN re-re-flash stock again. Only thing that worked. Thing is, it is a 2 hour-drive, 2 hours back. I would like to not make the trip. Is there anyone who could help me? Here or via PN?

Bump. Need this info also so I can safely try a custom rom and revert back to stock rom. I am on DN2103_11_C.11

Really? No one who can tell me how to do this?

[Q] I'm just completely lost with ROM's. Yes, I searched, forever.

I have a rooted Atrix on stock Gingerbread (I updated via OTA, the same for any previous updates.)
I rooted using the preinstall method, it worked fine.
Here are my questions:
I want to flash a custom ROM. Maybe Ninja. Is this possible when I updated OTA instead of flashing with an unlocked bootloader?
What are the steps required for flashing and still keeping all my data? I'm concerned about application data, camera roll, sms (I use Go-SMS), etc.
Is there a way I can make a "mirror" backup with all my data, so I can recover from it once flashing? (Is this nandroid?)
Once flashing a ROM, would flashing another rom or updating to a newer version require me to wipe my data and start over again?
I know ROM Manager recently supported the Atrix. Should this be my application of choice for CWM?
Pretty much, I want to flash a custom ROM and get all my **** back lol. I also want to be able to upgrade in the future while still keeping my data.
Sorry for being a n00b, this is my first android phone, and I'm loving it so far.
Thanks guys!

You must unlock bootloader if you want custom ROMs.
If you updated to 2.3.4 OTA flashing pudding sbf will semi hard brick your phone. But it's ok. You can recover by repeating the fastboot commands in the Pudding thread instructions. Or just follow instructions here:
http://briefmobile.com/how-to-unlock-the-atrix-4g-bootloader
From there on you will need to flash unlocked CWM recovery.
From there on flashing custom roms is the easiest thing ever.
Do we go from step 1, even though it says to go to 13 when you're on 2.3?

Nope. You need to start at step 1.
Make sure to install the drivers before doing RSD flash. x64 windows drivers here.
And to download the correct version of pudding for your phone from here:

So wait, the phone somewhat bricks and then needs to be recovered if we updated via OTA?
(Flashing pudding atleast)

It's really just an extra step, don't think of it as bricking. You'll likely get a 0x1000 failed to boot. Then you go abck into fastboot mode and re run the oem unlock commands.
As for data, you gotta buy titanium backup pro (free is fine, but then you have to manually ok each app you restore). Use this to back up your Apps.
Then I use my back up pro to back up my texts, mms, other stuff.
back up, install rom, restore.
Hmmmm ok, thanks!
Downloading those two to backup now.
I'm wondering if I should just wait for CM7 or not now haha.

You will still to have to do it after CM7 gets released. Better do it now and get it out of the way while you have the urge.
I am sure once you unlock, you won't be able to resist the temptation of trying custom roms
Just wanted to say, I followed all steps to the letter and unlocked my bootloader with no problems at all. So not everybody gets the 0x0001 type erorrs, either way though as they've stated, you can recover from it with fastboot so it's all good

backup using titanium.
unlock using http://forum.xda-developers.com/showthread.php?t=1182871 which is safer than sbf.
use rom manager to flash CWM. then do a nandroid backup (to create mirror image).
flash new rom (follow a guide)
restore apps using titanium.

To root, should I revert back to an older version of Android?

I just recently got the gingerbread update for my Fascinate and it didn't fix my ongoing GPS issue, in fact it made it worse. I'm going to root my phone and try a few custom ROMs to see if one of them will fix the issue. My question is, should I downgrade Android before rooting the phone or does it even matter? Is it even possible to downgrade using the Factory Reset option on the phone? Any and all help is much appreciated.
Take some time and read this guide...you dont need to root in order to flash a custom rom. Pick a section that interests you and follow directions!

[Q] Want to backup stock odin rom, root and unroot my i717R

Hey guys, I have found most of the info I need, but am still left with a few questions after going through the forums. Maybe I am getting old, but I don't want to take it apart if I can't put it back together, so to speak.
What I want to do, is root my Rogers Galaxy Note without tripping the flash counter, which I learned is to:
Use Odin to flash CWR, and then reboot and install superuser from sd card. No problems so far, that seems simple. The problem I have is with restoring it to full stock. If I perform the above mentioned steps, do I need to flash a custom image? How would I remove CWM and superuser? Would I need to flash back to my stock ROM, and then my stock bootloader? Also, how do make a backup of my Rogers stock ROM/kernel? I read that the existing one has a Telus splash screen.
I found this thread, but the member implies to use titanium backup....wouldn't that back up a rooted ROM?
And this one says you can't make image unless you are rooted. How would I be able to go back to full stock?

[Q] [HELP] Won't update anymore

Hi,
First of all I'm new here so please don't be too hard on my nooby actions from the past.
I have a rooted Galaxy S3 and 6 months ago I wanted to flash custom roms. I've read a lot about it and thought I couldn't do anything wrong anymore, so I made a nandroid backup (to switch roms when I wanted to).
Now here comes the noob part I didn't read about or I've looked over, my stock rom was android version 4.1.2, and the new rom was 4.2, when I wanted to go back to stock I softbricked my Galaxy s3, it was stuck in a bootloop.
I managed to get into Clockwerk Recovery and fix it, though I don't remember how I did it. I ended up with a factory resetted stock rom, but I was happy everything worked again!
So everything was okay and now that a new update will be available, I wanted to check if the update was available in my country yet, but my phone said that it wouldn't update because my phone is customized, so I checked in download mode and it says flash count 1, custom binary and custom system storage.
Is there a way I can get my updates again without factory resetting my phone again or without flashing the stock rom again?
I would like my phone how it is now with all its data, but just be able to get the official updates.
Oh and I freezed some system apps and bloatware with app quarantine, maybe that's important too.
thanks in advance for the help!
No, you can't get official ota updates unless your phone is unmodified, yours is very much modified.
If you want to go back to full stock, unroot and remove flash count then there are guides in general forum, stickies. You'll lose all your data in the process.
Instead just flash the 4.3 stock rom using odin, you might not even need to factory reset doing this. Follow the guides again, back up your efs first.

you must be rooted first and make the flash counter 0. use triangle away for that. would be better to follow some guides available here at xda..

just by flashing 4.3 stock firmware from odin wont work, he will need to factory reset, else he may be stuck in boot loop..
Okay so if I understand correctly: I can't get the official updates directly from samsung, unless I factory reset + flash stock rom again (because now I'm also on stock but download mode says custom) + triangle away + unroot?
Now all I want is the official stock rom 4.3 of the Galaxy S3 + root (doesn't matter if it's done via odin), without losing what I have now.
Is this possible to do in any way?
I would think of
1. making a full nandroid backup
2. titanium backup
3. flash 4.3 rom + root
4. restore via titanium backup
will this work for what I want as a result?
I will read some guides too if I know that this is the way to go, I just want to be sure of everything before I do anything, I don't want to screw things up like last time..
And can I choose what 4.3 I download? (European or even more specific like Belgium in my case?)
Thanks again everyone!

okay so I've read this thread http://forum.xda-developers.com/showthread.php?t=2362743 and there was a lot I already know (I'm not that new to rooting and stuff like that) but I didn't know the radio part yet, this gives me even more questions.
If I flash stock 4.3, will I have to flash a radio of my region too or won't the radio be effected by the rom flash?
I'm just confused now.. can somebody just help me with my questions? I'm not new to the forums I just never made an account, I've read many threads on here, watched videos, ect.
Thanks again
I would also do some reading up on the new 4.3 update whether you would want to upgrade to it or not when you fix the update problem because at the moment there are a few issues with it! All though that will change when bug fixes are released in the future but at the moment it has problems.
If I flash stock 4.3, will I have to flash a radio of my region too or won't the radio be effected by the rom flash?
Depends upon what region modem is in the firmware .
personally i am not updating to 4.3 until we get a better release .
Okay thanks for the advice everyone!
I will wait until a more stable version is released
And when it comes out, will titanium backup fix all my apps and paid apps as if the update was done officially?
What would be the steps I have to do, and please don't say google it or read every thread there is about rooting I came here for your help and clear answers, I need help from people who know more about this stuff because I'm no IT pro

Clean Unroot Help

I have an old rooted Note 3 that I gave to my child to play Pokemon Go on. With their latest update, they've banned rooted phones from playing the game. Very frustrating.
In any case, I unrooted my phone via SuperSU#, but the game's still not working. I tried to do a system update, but it says the device is "modified in an unauthorized way."
So I guess I'll have to re-root, flash a stock ROM, then unroot again? Will this work? Where can I find the latest unmodified ROM? I don't even remember how to root! This was over three years ago. Grrrrrrr.
Any advice much appreciated.
Downloading a stock ROM that I think I need to flash (six hour download).
But I need to re-root first, so I can flash the stock ROM I'm downloading, right? Does anyone know if I re-root then flash the stock ROM and then unroot, will I still get the "modified in an unauthorized way" notification under System Update?
BTW, I downloaded a Knox checker from Google Play, and I've tripped it. NAUGHTY! (Don't care, it's an old phone, but I hope that doesn't effect Pokemon Go playability.)
