About rooting and future update

Hello,
I was wondering, I'd like to root my OP3T , following the guide w/e here or on OnePlus forum. But will be my flashed update as stable as if I keep it on stock recovery ? ( Since people w/e they have OTA on stock or flashing new update on custom recovery )
Besides, I'm already on Nougat 7.1.1 if I root, I won't lose it right ?
And I looked for the right TWRP and the right SuperSu but on their guide are for MM 3.5.1 and not on N 7.1 so where can I find the right version ? on their Website ?
So thank you very much for your help !

If you root your phone, the System Update app will detect it and download the full ROM for each update rather than the partial update. This occurs regardless of the status of your recovery. Since root modifies partitions that the user generally does not have access to, the updater will always overwrite all non-/data partitions during the update. Plus, when you flash an update, it removes root anyways.
My advice is keep TWRP as a custom recovery. When an update is released, you can still go into the Update menu in Settings and download the full ROM (it will do so automatically if it detects root). Then just flash the full ROM in TWRP, flash whatever you used to root, wipe cache, and you're done. If something goes wrong, you can always use TWRP to restore a prior backup. The same can't be done for the stock recovery.

Ok thank you very much for those informations !
Still, do you know which version I should download ? Since I'm on 7.1.1 , thread only shows for 7.0
I searched and I found : SuperSU 2.79 and for TWRP it's the 3.0.4-1 ? Are they right ?

[Solved] Official Oxygen OS 5.0 boot loop problem for rooted users

Update: A working solution is listed below for reference.
A detailed tutorial for encrypted and rooted Nougat OOS users on how to flash Oreo OxygenOS without running into the infamous boot loop issue.
Step 1: Remove all fingerprint & pin from the device
Step 2: Backup everything on your PC/Laptop

Seeing as a couple of forum members have messaged me regarding the official update of Android Oreo, I would like to make a proper discussion thread for it.
I just want to make it clear that HatRiGt has made an outstanding effort by making a tutorial thread. -> ([OFFICIAL] [Stable Oreo 8 ] Oxygen OS 5.0 Update [Tutorial-Root] [Mirror] by HatRiGt)
With that said, I believe the title is somewhat misleading. Since a lot of members are under the impression that this Oreo update will be a simple and straightforward process like all previous Nougat updates, except for it's not.
Stock OxygenOS
Rooted with Magisk v14
TWRP Recovery
Device already encrypted
Almost everyone with the device configuration listed above has run into some sort of serious issues, such as boot loop, file system decrypted/corrupted, or a complete data loss.
So far, it seems like the few groups of members that have managed to update their device without any data loss are either users that have flashed the Oreo Beta rom, or users with a non-rooted & stock recovery device. Almost everyone else is facing some form of issues.
I understand that some people have suggested that rooted users should first format the internal storage, before proceeding with the Oreo update. I personally feel that it is an inconvenient method of OS update, since many of us have a huge collection of photos, media files and app settings etc... to worry about.
The purpose of this thread is to address the aforementioned problem for rooted OOS users and to come up with a solution, so that everyone can enjoy this latest stable release of Android Oreo.
Any comments or thoughts are welcomed.

Maybe a stupid idea, but I am a bit noobish in this. Running stock 4.5.15, rooted, K2 TWRP and Magisk.
Is it not an option to just flash stock recovery (via ADB or Root Toolcase), then remove/deinstall Magisk and use the OTA update? After that flash Blue Spark via ADB, reflash Magisk and be good to go?
Unfortunately this is my daily driver company phone so I haven't the time to experiment with it at the moment.

I had some issues trying to dirty flash mine. Didn't know about others' troubles until after the fact.
I ended up with the black screen and blue notification LED. Everything encrypted and unable to go anywhere in recovery mode. Had to do a full wipe and image load; I also am not sure if I had been running my backups for a while, so this could be a lesson learned.

Still experiencing the exact same problem.
The problem is, I can't transfer the zip to my phone to flash.
Under TWRP, any computer recognizes it as a mass storage, but even with adb push/sideload it doesn't work.
Does a full wipe help with that problem?

I saw the same thing. Unable to copy the zip file until I did the full wipe, which means no chance of recovering what was on it, but I'm cutting my losses.
I'm now stuck on the configuration stage, it's just sitting on "Just a sec..." for forever it would seem. Trying to update on Christmas day was a bad decision.

Root *shouldn't* cause issues. But that really depends on what has been changed by root
Twrp will though.
Flashing stock recovery should allow the ota to work without issues.
Having said that it's a major update so factory reset isn't a bad idea anyway.

I had the same idea, encrypted, rooted (no system modifications) and running twrp, I flashed stock OP5 recovery, and updated through the ota and ended up in a bootloop.
I did a nandroid to a usb before updating, but I still lost all internal storage files

so...the no verity is only for decrypted users right?

I appreciated the suggestion, but there are a lot of users with loads of files stored on the device, along with various other app settings, having to wipe the storage or perform a factory reset can be really troublesome. I believe that OnePlus pushed through this stable OTA update with the intention of a seamless update. Endless boot loops and data loss wouldn't be an ideal method of an OS update.

The way I installed the beta 2, was removing the pin and fingerprint before installing magisk through Twrp, at first I got stuck with bootloop, but made it come back to life after installing the ota through Twrp and booting back, removing my pin and then installing magisk.

Okay, so I've been thinking that maybe it's possible for us rooted Nougat OOS users to update to Oreo stable release without any form of data loss.
I've listed the steps to avoid any potential confusions.
You start with stock Nougat OxygenOS (Encrypted) with Magisk v14 (root) and non-Oreo compatible TWRP (e.g TWRP 3.1.1.1)
Flash an Oreo compatible TWRP (e.g Blu_Spark TWRP)
Boot up the new Oreo compatible TWRP
Flash OreoBeta 2
The phone should boot up OreoBeta 2 without any data loss
Dirty flash the official Oreo stable release via the new Oreo compatible TWRP
Flash Oreo compatible TWRP again
Flash Magisk beta for root access
Flash No-verity file
So the basic order of flashing should be Nougat OOS -> OreoBeta -> Oreo Stable
Any thoughts on this?

Are you sure flashing Open beta2 won't compromise the internal storage? I bet no one affords to loose previous photos, apps, settings, etc without full backup.

I've triyed this. All good till i flash 5.0 & Magisk & no verity....

Hello there and Merry Christmas.
I faced to this issue too, fortunately before to update to Oreo. I made a full backup of my data.
My OP5 was running under Oxygen OS 4.5.15 Nougat 7.1.1
Rooted with Magisk V14.5
TWRP Blue_Spark 3.1.1
First I have updated my TWRP to Blue_Spark 3.2
And then I've installed Oreo Oxygen OS 5.0 from TWRP with the full zip.
After the update, my op5 has been bricked and locked on blank black screen with a blue led.
To unbrick my phone I used a tiers softwate to install Hydrogen OS first.
After that I could installed TWRP Blue_Spark 3.2 and then flash to the full zip Oreo Oxygen OS 5.0
My OP5 works as well but...
Right now I'm blocked, Google who usually sends an SMS, does not offer me. Only the authentificatorator or the security code. : /
Be careful, print a Google code to access your account when you go to install Oreo.
I'm waiting for Google to do the right thing.

Hi,
I have a boot loop on my OP5.
I ddirty flashed Oreo and had twrp/magisk.
Any ideas to recover my data partition ? (I had fingerprint/pin)
Best regards,

1) What is that "no-verity" file?
2) Isn't the regular TWRP 3.2.0 good with Oreo?

Isn't a full wipe required even for Oreo Beta builds? Also thanks for starting this thread I'm really eager to jump into Oreo but would love it if no wipe happened.

I think it's possible to flash the Oreo Beta without a full wipe. And yeah, I've got way too much stuff on my device, so I can't afford to wipe my storage.

I never suggested either.
Oneplus don't test using twrp or using root.
Their prescribed ota route, as pretty much every other OEM, is unmodified system partition using stock bootloader.
Twrp or root will affect those and can cause bootloops.
Obviously there's a chance with so much diversity in installs that there can be an issue arises.

Actually I was able to restore my Nandroid backup.

Any chance to root without wipe/delete/format data?

Hi everyone,
I really looked many websites and I think the answer is no but I still wonder if there is a way to root MI 8 with magisk from twrp without format the phone? I am running latest global stable rom with unlocked bootloader. I just want to root and install magisk for certified play store, netflix and adaway but setting and installing all apps again will take some time... As far as I know it was possible before as I did it at a MI 6 running miui 9.
Thanks in advance.

No

magisk, Boot Image Patching

YES! I finally figured out how to get root and keep encryption with Stock Global but you have to flash an alternate kernel first. You can keep your encryption without issues. I've been using this for a few weeks without issues now. The STOCK kernel has been the issue the whole time.
For Stock MIUI Global (Beta or Stable) Already Setup & Encrypted:
1.) Boot to TWRP Recovery (i'm using twrp-3.2.3-4)
2.) Flash Sphinx kernel (i'm on v2.5) You CANNOT keep ROOT while retaining encryption on a STOCK Kernel at this time!
3.) Flash Magisk (i'm using 18.0)
4.) Flash Disable_Dm-Verity ONLY! (DO NOT FLASH DM-VERITY with Encryption REMOVER or FEC in the filename or you will screw up your encryption!)
-I use this DM-Verity remover here: https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389
-you need to re-name the zip file with only "DM-Verity" in the filename without the ForceEncryption in the name before flashing! The filename determines/triggers what the zip disables!
DO NOT ERASE OR FORMAT ANYTHING!
Reboot and enjoy root while retaining encryption.
-You need to follow these steps on every new ROM flash!
-You can't do OTA updates, you need to flash new full ROMs!

Oh sorry I missed that he's already unlocked the bootloader

I can confirm this works, or at least in global ROM. I tried flashing Xiaomi.eu rom from global, but I couldn't boot it. I remember someone said that rom doesn't have encryption implemented.

Hey guys, do you know how to install global properly? I have installed the last one, but i can't change region it keep up on china region, and the baterry drain is bad. I used twrp recovery, but when i installed the global rom it doesn't work anymore, it started the miui recovery instead of custom. Help please

I installed magisk without a reset easily. Also im on stock kernel and my phone's encrypted ?

what is encryption for?`sry for maybe stupid question :x

Well your files will be encrypted so noone can access your files without the encryption password if the phone gets lost.

Hello, I'm running stock MIUI 10(global) on my Mi 8. It is already rooted. I was flashed DM-verify with encryption remover. Then rooted it.
Now I want to encrypt my phone without wiping data. I tried flashing Sphinx kernel then encrypt the phone but it failed. Should I reset my phone and setup again to encrypt the phone or it is possible to encrypt it without resetting?

Running Root on G6 since July '18. What are my options to upgrade software?

Dear all,
I've rooted my phone in July 2018 with the latest stock build from that timeframe. I'm getting notifications of OTA updates for the past 6 months that I've been swiping away and putting off. Obviously I cannot update OTA.
What are my options to update my phone if I want to maintain root? Is there a full build somewhere that I can install via twrp and flash SU or magisk over? Are there fully functional ROMs that I can periodically flash via TWRP to stay up-to-date and rooted? Or am I forced to revert to stock, update via OTA, then re-root?
I'm familiar with rooting but the G6 pathways have confused me compared to my previous OnePlus and Nexus phones. Thanks for your help.

You should only have to re-flash
OEM
Vendor
Boot
Recovery
to be able to apply the OTA.
Afterwards you just need to boot the twrp and install Magisk again, and maybe use the dmverity patch to disable forced encryption. <-- This has to be done BEFORE the first boot of the upated system, otherwise the phone will be encrypted again.
At least this is how it works on the G6 Play.

So basically I have to go back to stock, upgrade via OTA, and redo the entire root method, while wiping my phone clean each time with the OEM installation. Wish there was a more efficient way. Thanks for your input.

You can do that without loosing your apps/userdata.
Best bet would be to find the latest full image for your make/model and flash everything via fastboot. Just skip the part "fastboot erase userdata" or something like that, and you are good to go. Just remember the dmverity thing, if that is important/applicable for you.
Re-root is necessary either way, but that takes like 5 minutes, that shouldn't hold you up.

Brazilian PIE full ROM is out. If unencrypted, backup Oreo data in TWRP first. Second, you can fastboot flash this stock PIE rom & Reboot to PIE which will encrypt data. Third, fastboot flash unofficial TWRP recovery by Dejello (official TWRP can't install gapps for GSI ROMs and doesn't backup vendor partition). Fourth, format data to rid new PIE encryption. Fifth, install Universal Force Encryption Disabler 2/4/19 and Magisk 18.1 to root and prevent encryption. Sixth, restore unencrypted Oreo data.
If you're already encrypted, then do as above

There's a lot of mentioning of encrypt and unencrypted. If I'm starting over and wiping clean, what's the simplest method to maintain root? Staying encrypted or unencrypted?
The Brazilian PIE mentioned something about playstore uncertified. What does that mean?
Thanks!

If u want to backup data partition on TWRP, u have to be unencrypted for Moto G6 as TWRP can't decrypt data.
Rooting is just Magisk 18.1 and has nothing to do with encryption.
Uncertified is due to 1) unlocked bootloader, 2) Brazil ROM in USA--means little functionally

Few questions regarding rooting and flashing.

Hello XDA fam, I just picked up a 3T and unlocked the bootloader.
I was just wondering what the general flashing process was for this
device (A3000). Also a tad confused about this dm-verity ...
disabler zip, is this and format data required every time you flash a
new ROM?

Dm-verity warnings are similar to the unlocked bootloader screen you get, but are red. You get them if you are running stock OOS and modify the system partition.
You don't need the dm-verity disabler unless you've got a dm-verity warnings screen.
Note that you cannot disable the unlocked bootloader warning you get every time the phone boots except by re-locking the phone.
Another thing to note: if you are running stock OOS and flash TWRP, then TWRP will be replaced by the stock recovery when your reboot the phone unless you:
- use a patched boot image like the one from @Xennet's thread https://forum.xda-developers.com/oneplus-3t/how-to/dm-verity-disable-oxygen-os-t3922324/post79357241
- use a custom kernel, or
- use Magisk.
Flashing using TWRP is just like any other phone. If you're changing ROMs then you need to do a clean install (wipe /data and/system).
Some ROMs don't handle an encrypted phone (most Android 10 ones except for Los and PE), so you you have to remove the encryption before using those ROMs (TWRP>wipe>format data).
Finally if your phone is unlocked and running OOS 5.x or lower, and you want to upgrade to OOS 9.x then you'll either have to:
- remove the encryption (but can re-encrypt after installing 9.x) or
- use the modded firmware (that keeps the 5.x bootloader and keys) so that you don't have to remove the encryption. See https://forum.xda-developers.com/on...-5-0-8-firmware-barrier-t3941164/post79758055

Wow thank you for the detailed info, I really appreciate the insight.
I am currently running the latest OOS update 9.0.6 I believe.
Once I have TWRP installed do I swipe and enable modifications?
Flashing Magisk afterwards avoids the bootloop and allows me to
keep TWRP in place of the stock recovery as you said, correct?
So installing most ROMs seems fairly straightforward, following
the flashing instructions. However if I were to install an Android
10 ROM wouldn't formatting data remove all zips and everything
from the internal storage? So at that point I'd have to copy back
all my ROMs and zips back to the phone in TWRP and flash from
this point correct?
Sorry for the loads of questions, my most recent device was a
Note 9, which has a locked bootloader, so it has been a while since
I have flashed anything or used TWRP.

You don't need you enable modifications of the system partition. Any zip you flash will make the system writable if required.
So, just flash Magisk.

Correct. So it's best to take a backup of your current system and backing up everything on internal storage (/sdcard) to an external drive or PC.
The fastest way to take the backup is to use ADB.
Code:
adb pull /sdcard

You'll find that nearly all the rom, kernel, and recovery development threads are under the OnePlus 3 forum in https://forum.xda-developers.com/oneplus-3/oneplus-3--3t-cross-device-development as they are unified: good to flash on both the 3 and 3T.
