Unroot Oneplus 6 on Android 9 - OnePlus 6 Questions & Answers

Hello,
So my Oneplus 6 was rooted on Android 8.1 for a while now. Recently i got the update for Android 9 and did the official OTA Update to 9. Now my root seems gone or at least it doesn't work anymore.
Now I actually want to remove the root completly because I want to use my banking app, which won't work on rooted phones.
How do I remove the leftovers of this root? I had Magisk + TWRP on it. TWRP shouldn't affect any apps right? Would it be enough to just relock the bootloader? Cause root seems gone already there is no need to uninstall it right?
Thank you for your help.

you need to flash boot.img and system.img from the start. You can dump them from the OTA you have installed.

Just flash full ROM zip file in TWRP. Data will stay in tact, stock boot img and stock recovery.

Recevied an update with rooted phone, is it safe to update ?

I'm currently on NXT-29C185B190 and I received update with NXT-29C185B1200, my phone is unlocked and rooted, I have flash fire installed and it recognized that update was downloaded.
My question is flash fire have big red huawei device warning, saying Huawei device is very easy to hard brick (also my mate 8 is my first locked bootloader phone) so is it safe to use flash fire ? or install update throught huawei system without losing root ?

Is this an EMUI update through the standard update menu in settings - updater?
The version seems a bit odd to me, the last update for C185 was B320, I wouldn't expect an official update to jump as high as that. Mind uploading a screenshot?
Anyway, as for actually updating, as long as you are running stock recovery (not TWRP) then it shouldn't be an issue. Just know that you WILL lose root after updating. And I'd strongly suggest making a data backup before the update.

Thanks for the help, I tried to user flash fire to keep my root but it failed to update, now I really think rooting huawei phone is more trouble than it worth as for what you said is version is typo
I'm currently on B190 and I got update to B200.
and yes the update is standard update from system updater
I have twrp installed so that means I can't update at all ?

Well if you unlocked bootlader and rooted, it safe to say that you have TWRP installed, fire up SRKToolHuawei choose (2)install recovery then install stock recovery after that it reboots and then update using system updater from huawei.
PS: You will lose your root access and new to install TWRP then root again.

Thinks very much

Updating from 4.4.4 to 6.0.1

Hey everyone,
I have a Nexus 5 that I haven't updated in a long time that I'd like to get the latest possible OS for. The only modifications I've made which I think might be important are:
Unlocked bootloader
Rooted using SuperSU (v2.8.2 currently)
Installed XPosed (installer v2.6.1, not sure what version of the framework but it should be the latest supported by 4.4.4) with a few modules
Installed App Ops and removed permissions from some apps
Installed StickMount
I don't believe I have any custom recovery installed (I'd used a script to root and install XPosed originally and I don't know if it made any other changes). I'm comfortable using adb if needed but I'm cool with tools like FlashFire too.
My end goal is to have an updated OS with root and XPosed. I assume I'll need Magisk for XPosed, but not sure about root.
How should I go about doing this? I'm cool with losing all of my data (I'll be making backups with Titanium Backup) though knowing ahead of time if that'll be the case would be nice. If it's possible to update without losing data and without affecting anything that'd be nice, but maybe a clean start would be good? The OTA guide on this forum is only for 5, not 6, and most online guides start with 5. I don't want to mess up obviously. xD
Any advice/steps would be appreciated! Thanks!

The link you gave doesn't have the latest 6.0.1 build and it also says that it requires a minimum bootloader (HHZ12h) that I don't have (I have HHZ11k). Would it be possible to use the latest build from Google? What do I do about the bootloader? And would using TWRP as the recovery prevent me from passing SafetyNet?
Thanks for replying!
Could I follow this guide with the latest factory image and then install Magisk, root, and XPosed? https://android.gadgethacks.com/how...actory-images-android-using-fastboot-0175277/
If you're on stock, update using the built in updates. That'll get you all the latest firmware. I'm pretty sure the N5 goes up to 5.0 normally.

Would I have to do anything to XPosed or supersu first? I'd like to update to 6.0.1, too. I've seen online that there are OTA updates for it too.
Nope. But you may have to reinstall root, which is very easy once you're updated. Just let the updates do their thing, and you'll be on your merry way! Hope I helped
I think what I'll do is flash stock 4.4.4 keeping user data and then use the OTAs to update to 6. That way I have a clean system install to use Magisk with without losing any user data. (If that doesn't work I'll just flash 6.0.1 for a clean install.)

What can unlocking the bootloader and not rooting the phone do?the possibilities?

Checked out realme's website and they state that unlocking and flashing roms does not void warranty but rooting the phone does.So what are the possibilities/things one can do with the phone while unlocking it but not rooting it.
Also is there a safe rooting method which doesnt leave traces after unrooting again? So that the device can be used in warranty.
Thanks in advance for any advice.
If you have Realme 5 Pro (not q) then you can still flash custom rom, recovery or basically anything with adb. It's just you won't be able to do root stuff on your phone but you'll need pc. Still you could flash custom kernel, rom, or ota update. Magisk is called systemless root for it does root your system without touching the system files so after uninstalling it and flashing stock rom realme service shouldn't ever be able to tell that your phone was ever rooted. I live in Hungary and my previous Xiaomi phone was installed with custom rom, kernel and Magisk root. Before taking it to Xiaomi service I did a clean flash, reverted everything to stock and warranty was still good to go. That'd be just an example. Don't know Realme how is with these stuff.

You're welcome. If indeed only root void warranty then you're free to flash to your linking almost everything via usb adb. Except for root ofc.
thank you again for the same.

After installing twrp via adb you can flash stuff from your sd card. Don't forget to always have a backup zip file of your stock rom in case something goes wrong. And don't forget to use backup in twrp for data partition sometimes when you feel you're about to do something risky that might flip your system's stability. I do that all the time ?*
Yep I will.Its a new phone so more of a reason to take precautions .

Magisk has an option to hide from those apps, I used it all the time with secure banking apps
If I unlock bootloader and flash TWRP, can this TWRP can be used as my stock recovery further for flashing zips(not custom ROMs)? Also will Bank apps work in this set up without any problems?
Yes, you can use TWRP to flash anything. Yes, bank apps will work as long as you have magisk installed.

removing twrp through system update is it possible?

I unlocked my bootloader installed twrp and magisk, and i did not like it so I uninstalled magisk wiped and now I would like to remove twrp. is it possible that if and when android 11 is released it will remove twrp and relock the bootloader? Im on the T-mobile version.
Yes, flashing your current OOS full OTA zip via system update on your phone will remove it.
Flashing 11 when it comes out will do the same.

Question Downgrade LE2115 from 12 to 11 - confused.

Hello all,
My phone came with ColorOS OOS 12 and I hate it. As soon as I rooted it it started crashing daily, I even reflashed a fresh oos12 image using the local update tool and only granted superuser to one app (solid explorer so I could access user files) and it still crashes. Not to mention all the apps i want to use don't work on android 12 (call recorder, busy box) and no custom recovery.
I've been reading through the forum and I found a downgrade package that looks like its hosted by oneplus: https://oxygenos.oneplus.net/OnePlu...all_2107082125_downgrade_059624cc7298428b.zip
I just wanted to make sure I am doing this correctly...
Do I use the OP Local Update app to flash?
Will I be able to flash TWRP for android 11 afterwards?
Will i need to relock the bootloader?
Should i re-root using the magisk slot b method or wait until its flashed and use TWRP?
Will it try to OTA back to android 12? If so, what's the best method to get on the latest version of android 11?
Thanks for the help.
I am running COS C.62 on my OP9 with root and having no issues. Did you make sure to do all the things in this guide?
Root OnePlus ColorOS 12 OxygenOS Android 12 via Magisk
In this tutorial, we will show you detailed steps to root your OnePlus device running ColorOS 12 Android 12 via Magisk Patched Boot.img file.
www.droidwin.com
Anyway, yes, use the local upgrade APK, put the downgrade file in the root of storage, run it. Reboot. Factory reset and wipe data to clear out any leftover crap (don't restore a backup - if you want to use Clone Phone you can do that but only restore app APKs and messages). When it reboots it should offer the latest OOS11 OTA first. If not, just download it and place it in the root and use the local upgrade function in the settings menu of the OOS11 system updater.
There is no need re-lock the bootloader and if you do, you risk a brick that has to be recovered with MSM Tool.
Root by following the guide I linked. I just went through this yesterday after flashing COS broke mobile data. I have Magisk 24.3 working with denylist, Widevine L1, and SafetyNet passes so I have Google Pay.

Thank you, ill give it a try.
First i used the payload.bin method and it was crashing, then i reflashed the latest OTA using the local update tool and used the magisk slot b method. still crashing.
It might have less to do with the root and more with me using root to disable certain apps (youtube, chrome, OP community, google news/podcast/tv) i dont want them on my phone but they might be too tightly integrated. If its still crashing on android 11 ill re-enable them and see if that helps.

Okay you're on OOS, not COS. COS doesn't have Google apps by default (but has plenty more bloatware, I just don't use it).
It's certainly possible that disabling Google apps is your problem. If you don't want Google apps, you're better off with a custom ROM that doesn't have them. CalyxOS has a beta for OnePlus 9 and it's totally de-Googled. There's also Lineage.

ahhhh. i didnt realize there was a difference. I thought OP was just calling their android 12 build ColorOS.
Either way, for custom roms i would have to go back to 11 to flash TWRP right? or can you flash custom roms using fastboot?

You would need to back to 11 because OnePlus hasn't released working sources for 12. Just use the downgrade package, factory reset, then upgrade to 11.2.10.10 and you'll be good to go for custom ROMs. TWRP isn't used for flashing them, they all generally post their own recovery. StagOS was the best one I used (plus the dev is really responsive when there are issues) and people seem to really be enjoying Nameless but that came out after I went back to stock so I haven't tried it yet.
Before you mess with custom ROMs, make sure that you download the global MSM Tool and make sure you can connect it. Honestly since you have to go back anyway, might as well download and use the MSM Tool to get the device back to 11 anyway.
GLOBAL OnePlus 9 MSM TOOL UPDATED
Frist off Im not responsible for anything that happens to your phone!!! VERY SIMPLE IF YOU ARE BICKED,BOOTLOOPED OR JUST WANT TO GO BACK TO 100% STOCK THIS WILL WIPE ALL DATA!!! AN RELOCK BOOTLOADER OOS 11.2.4.4.LE25AA MUST HAVE QAULCOMM...
forum.xda-developers.com
Easiest way to get it into EDL is adb reboot edl but if you want to practice the key combination in case you can't get into the OS, I found if you open the MSM, check use lite firehose, and click Start before you connect the phone, it has less connection errors because it's waiting for the phone so as soon as you connect the cable, it pops up.

Yeah TWRP has issues. I soft bricked last time I tried to do anything with it and had to use MSM Tool to get back to working order.
