Hi, I rooted my a9 back in May right around when 6.0.1 came out. Long story short, my device just gave up the ghost after a nasty interaction between the screen and concrete, so now I have a new device being shipped tomorrow. I figured the first thing I'll do is let it run any updates / OTAs it might have to get it up to date then attempt to root again.
I've been looking around for the past several hours trying to determine what the correct rooting method might be now given Nougat's rollout, but I haven't come across anything truly definitive yet. If anyone could enlighten me on what I'll need to do now to root this new version I'd be very appreciative.
Thanks in advance guys!
Just got the phone today and updated to 7.0 (software version 2.18.651.2) Still searching around and not seeing a definitive answer on whether or not the old method for rooting works for this or not. I'm hesitant to attempt it without knowing, so any advice would be greatly appreciated.
Last time I rooted, I used Windroid toolkid to unlock the bootloader, flash TWRP and apply SU. I'm wondering, would the same program work if I replaced the recovery.img file in the Data folder with the TWRP 3.0.3 unofficial recovery I saw floating around in here for nougat?

You can unlock it on the HTCDEV website, although if you've already got it unlocked I doubt you need to do it again. To root I just ADB fastboot flashed TWRP 3.0.3-4, then used that to flash Magisk, mounting system read only. I'm fairly sure some people are using Su on Nougat, so it'll probably work.
Never used the Windroid toolkit so I can't comment on that, but I've also never minded typing commands to the prompt. I'd imagine if you gave it the right TWRP it'd flash it OK..

That actually doesn't sound too bad; From that it seems like the process is still more or less the same. Why is the system mounted as read only though? After looking through most of the older step by step guides it doesn't mention anything about doing that. From what I see, after i run the command "fastboot flash recovery recovery.img" i boot into TWRP and then proceed to do a factory reset and wipe the cache, presumably to remove the encryption iirc, then install the supersu.zip is that still the correct procedure, or does this require mounting the system as read only now?
If you don't mind me asking, what steps exactly did you take to root yours? from what I've found all I need to do is get the bootloader unlocked with the steps from HTCDev, drop into download more, fastboot flash recovery recovery.img to get TWRP, boot into TWRP, run a format to get rid of the encryption, then install supersu.zip and that should be it. IS this correct or am I missing something?
I'm about to start the process trying to root using the above methods.. I'll post again when I have results.

It wasn't bad at all. The reason I mounted R/O is because I'm using Magisk and not disabling dm-verity. I'm not sure if it works the same on 7, but SuperSu should disable dm-verity, so if you're using it you might not need to mount R/O, I haven't been keeping up on that at all. Benefits of Magisk include Android Pay and being able to take an OTA.
That all sounds like exactly what you need to do, except I believe it's fastboot mode (the one with the black screen?) to flash TWRP. I also didn't have to format anything, but I believe you do if you're using Su and disabling forced encryption. You may want to take a system image backup before you change anything, so you can go back to stock and get an OTA, or in case something goes wrong, but other than that it sounds correct to me.

huh... Magisk can utilize android pay and OTA's? I'm a little bit intrigued.. I just might have to give that a quick look now. Was it difficult to get up and running, and is there a fairly decent guide for doing it?

Magisk is a framework for systemlessly modifying /system, so safety net works and you can take an OTA (with stock recovery), and also includes root. It's brilliant, but not quite as powerful as Xposed. Not difficult at all to get running, all it needs is to flash the magisk installer zip in TWRP (system mounted R/O of course) and then install the Magisk Manager app from the play store.

Did just that. Got TWRP installed successfully. I PM'ed you a second ago but I might as well ask this here for everyone else to see in case someone else is wondering this too.... So if I'm understanding Magisk correctly, all I do now is hit install and choose Magisk v11.1?
Edit: I did just that, but it doesnt seem to have done anything.. I dont see and magisk apps, and root checker says i'm not rooted.. Did I miss something?
edit 2: scratch that... I just installed the magisk manager app from the playstore.. according to it, the latest version of magisk is in fact, installed, and it's rooted with magisksu (despite not showing so in rootchecker).. Little confused now. Is that everything that needs to be done?
edit 3: I went back in after seeing something mentioning installing phh's superuser via TWRP and installing the app after installing magisk. Did both, but noticed safety net wasn't passing. found an option in settings to hide magisk, which seems to fix that. I also ran root checker again and it shows I have root.
unless I missed anything you can think of I think that about finishes things. If thats it thank you for all the help @JohnRogers23

I'm glad you got it working. Strange you had to flash phh's Su separately though. Anyway, glad I could help.
Well Working !
1.Backup your all imp data from internal memory
2.Flash TWRP 3.0.3-4.. Do not reboot into system and enter into Recovery TWRP..
3.Do a factory Reset via TWRP.. Do not reboot into system
4.Now flash SuperSU 2.79 SR3 via TWRP.. Finally Reboot into system..
*2 bootloops are common, do not give up for at least 3 bootloops..
*It will take a long time to boot as you have done a factory reset.. So be patient and wait for at least half hour..

Thanks! I got it more or less and went with magisk. Couldn't pass up a chance to have root and still get OTAs and use android pay. I'm still monkeying around trying to figure out how to use it to get liveboot back up and running.
I've wrote it in many thread and I report here for users that want:
stay stock and updated
root (with Magisk)
unencrypted
never lose data and configuration
Here's my procedure, I'm using it since since I bought my S8 exynos (jun 2017), never had a problem, never lost a single bit of my data. And I don't know any alternative until now.
G950FXXU4DSDA (pie) tested​
I assume you have:
unencrypted device
oem unlock option checked (never uncheck it)
stock rom: any system mod is ok, but you'll lose it
What you need:
last odin (download here)
last stock rom for your country (download here)
last twrp on your exynos device (download here)
last Magisk zip on your device (download here)
Here's the steps:
if you haven't did before, create a magisk config file executing this two command on a shell (this file remain until you clean /data partition):
Code:
echo KEEPVERITY=false>>/data/.magisk;
echo KEEPFORCEENCRYPT=false>>/data/.magisk;
extract the rom and delete CSC_OXM_G950Fxxx (you don't need it, this file do the factory reset we don't want)
reboot you phone in download mode (boot with voldown+power+bixby)
connect your phone (you already have the driver, right?)
select all files in odin
uncheck auto-reboot option
press start
at the end manually restart the phone with voldown+power
the phone will boot in stock recovery and complete the installation ("Installing system update..." and "Erasing...")
keep attention because when rebooting you have to put your finger on voldown+power+bixby to return in download mode (if system boot your data partition will be encrypted)
in odin select TWRP file in AP slot
check auto-reboot option
put your finger on volup+power+bixby and keep there
press start
after a while you'll be in TWRP and you can relase the finger
flash Magisk
reboot in system
Then you can do any other mod you wan't, my favourites here.
I wrote this thread because all the guides I found skip the important (and tricky) 9-10 step and my tests results in:
interrupted csc install (twrp tried to execute a script producing "Error installing zip file 'CACHE:recovery/sec_omc.zip'")
empty CSC (Phone Info app) and no /system/omc folder
phone works well, but i'm not sure I was using VoLTE because I didn't see the icon
dial codes aren't working
korean operator "KT" voice in settings
Anyone else tried this method? Hoping to give it a try later this week when I have some time should something go wrong
so on s8 works too. nice. I've been doing this on my S7 edge every FW update. dirty flash, then root then xposed. So I hope this trick works in my S8 too.
are you on Nougat or Oreo?
Yea it works just fine, dirty flash can cause issues though. Might wanna let people know that.

if you've never modify the phone, you're encrypted
if you,re encrypted, you need to format your data partition to get root permission (for what I know is not possible / not safe to stay encrypted)
you can follow my guide adding a format data step before flashing supersu, but the phone will be factory reset
so after doing this i'll still get ota updates and i can install them fine plus having the root privileges ?
No, I've never tried ti install otas (I expect it will fail).
To stay updated you have to repeat the procedure whit the new stock image, usually released before the ota.

Does is still work? I want to upgrade to Pie but dont want to wipe and lose all data.

@c3k ,
Thanhs for this great solution !!
m.
I still have the stock rom and rooted with magisk. But in twrp I can not mount the data partition. Is it because it's still encrypted ?
... that's what I assume but it`s strange because you should be decrypted already after formatting data installing twrp, magisc etc. ...
m.
Yeah..I know...any suggestions ?
... it sounds like a data format is needed then ... Or does this method from c3k work for you ... ?
You `ve the latest TWRP installed?
m.
How do I install the latest one if I have an older version ? Can I use flashify for it ?
Or with twrp itself ?
I install new twrp via the installed one as an img file.
m.
This thread is not about "How do I install twrp" etc. But maybe this can help some of us.
I got a question. If I install twrp and root, am I still able to install system updates? For example, oxygen 5.1.6 comes out. How do I install it?
Have a nice day!

Probably not if it's rooted,in terms of it updating its self. Most likely someone will upload a zip file to flash over the old version though

Download the full room zip file, install with TWRP just as you would with a custom rom. You will lose root so you would have to repeat that process. It may differ because of the a/b partitioning, but that is how it worked on op3t. As always, backup data. And also SDcard in case you can't decrypt. Also delete lock screen before flashing.

What if I have Xposed installed? Will the update go fine with that as long as I disable Substratum overlays and am flashing the full zip and then root afterwards? Or do I have to disable Xposed in Magisk or what? (I use systemless xposed)

What he means is delete the lock screen security so a pin/pattern/face unlock/figerprints... anything other then swipe to unlock your phone because if you have them set and you install a new ROM or flash the Stock ROM then it can't decrypt your phone data or recognize your security on the new ROM.
This also goes for doing a nandroid backup of any current ROM you have installed. Delete all security before booting into TWRP and backing up your ROM.

Regardless, it will still wipe system. Think of it as a complete factory reset. It will reinstall the full system and data of a brand new room.
Hello, I'm still a noob trying to learn, so far with help of this forum I've learned to unlock and root my first android phone, now I'm trying to learn how to properly keep my device updated!
Can someone please give a little rundown to what are the correct steps to update OTA on a rooted twrp device?
I've been browsing the forums a lot but I seem to find a lot of different approaches, or too vague instructions.
It would be greatly appreciated if someone could help me out, step by step, and explain the steps with the commands I need to put in, if there are any.
Thank you
download the ota from here
place it on your phone
go to update on you phone then hit the cog and hit local update
let it up date
reboot to boot loader
fastboot twrp img again
then flash the installer
reboot recovery
then it will boot back in to recovery again
flash root
job done
Hello,
To save you having to fastboot boot TWRP, do the following:
Save the following files to your SDCard:
OTA.zip
Magisk.zip
TWRP.zip
Boot into TWRP
Flash OTA.zip first, then TWRP.zip straight after, then Magisk.zip straight after that, reboot.

You can flash the installer zip for TWRP through TWRP itself.
Doesn't installing OTA through system settings wipe TWRP? That's why I perform all my updates from TWRP directly.

It prob doesn't overwrite until u reboot so twrp may not have been overwritten on that partition yet, so would make sense, I need to try it out sometime
When you install OTA via system settings and reboot, the slot switches to the inactive one (where the OTA installed to) and boots. This means the previous slot (prior to reboot) still has TWRP installed.
You are probably going direct to recovery after the OTA install without doing a full reboot first.
Swatto is correct. The risk when using twrp is that you must reboot to recovery immediately after flashing the twrp installer zip, or you will boot to the old slot and things will be broken. Rebooting to recovery gets you onto the active, updated slot.
When you reboot to recovery and flash an OTA, you are flashing it to the other slot. The current slot is untouched, while the new active one is completely stock. The twrp installer zip flashes twrp to both slots.
This is the procedure to follow if you want to update via twrp. Personally, I prefer taking the OTA and reinstalling via fastboot just to make sure everything is clean.

Alright everyone, thanks for all the replies. I have to say even with all your help things were still really confusing for me. I went ahead and ditched TWRP (since I don't really need it anyway), updated OTA through the system, reinstalled magisk before reboot on 2nd slot (the OTA option), and rebooted. And so far all seems fine, I'm on the latest OOS version and I'm still rooted, everything seems to work. Can I do this again in the future and completely overwrite my TWRP installation on my A slot?
I kinda went with TWRP as it's supposed to be more safe for noobs but it ended up making things a lot more difficult to manage.
Thank you

I have not tried that method as I want twrp, but that is the recommended approach.
I know things have changed with twrp, but it's not that hard once you get used to it. You just have to remember that your phone will switch active slots every time it gets an update or you flash an ota (for example, to go back to stock), so twrp, etc, have to be installed on the other slot before you boot to it. Once you get comfortable with that idea, the rest of it is pretty easy.
Well, I am glad to read this post. Its always interesting how things can be slightly different in every phone manufacturer's setup.
After my lady Huawei device (Honor 6x), I did not want to have to deal with their style of... Control over their devices.
And things seem much easier here, while also being a little confusing right now. I don't fully get the slot a/b stuff yet but it sounds like it's a system to ensure stability on the phone in cases where the newest update could install incorrectly the alternative slot has a backup to ensure the device will function.
Sorta sounds like the dual bios setup on some motherboards. It's good!
Right, so to summarise to ensure I got it right:
1) Downloaded large (1gb+) ota zip from one of these threads, official twrp recovery installing zip, new version of magisk recovery installing zip
2) in recovery install all 3 of those zips in that listed order
3) reboot to recovery again to ensure twrp is still installed
4) profit
Which twrp thread should I take the zip from? There are a few different threads. I shouldn't care about the fastboot version when I already have twrp installed, right?
Either way, it can be much easier than what I had to do on Huawei phones. (currently the easiest phone I used for customisation like this was Nexus 4, but gladly OP6 is getting pretty close to that same level).

You're best off downloading from the official twrp site. If you already have it installed, no need to use the fastboot boot method. You should to reboot to recovery in between flashing twrp and magisk to be sure magisk gets installed on the active slot.

Question, more of a scenario really. So if I'm on slot A and have TWRP and Magisk installed, would it be alright to just do a local update and reboot, giving me a perfectly clean install in slot B? Does it work that way? Thanks!
I'm actually using a 6t, but worst case scenario I just use the MSM Download tool, still I wanna get the hang of these confusing A/B devices.
I'm at my wit's end here. I know I'm probably missing some critical step, but I haven't been able to install any OTAs since installing TWRP and Magisk. Fortunately, I was able to update to the latest TWRP before trying (the one that has working decryption) and backup Boot, the two Systems, and Data. I cannot stress enough how important this is!.
The OTA installer detects the device is rooted (or unlocked, if magisk isn't installed) and downloads the OTA. It then asks to install (which is does while booted to system, presumably to the side (A or B) that isn't updated), and asks to reboot. After reboot, the system fails to boot, then goes to the original OnePlus recovery (with the Chinese characters).
I seem to remember reading somewhere that I needed to shut the phone down instead of rebooting, but that doesn't seem to help. I want to know the correct procedure for updating, but I also want to better understand what is actually going on. I'm guessing the boot image on the other side gets overwritten by the OTA, which then flips you to that side, but I don't understand why it doesn't boot. Non-patched boot.img, I suppose?
These steps worked for me:
1 install ota
2 flash TWRP_A_B_Retention_Script-Magisk.zip via magisk
3 install magisk on inactive slot
4 reboot

Awesome. I had not even heard of the retention script, but it sounds like exactly what I'm missing.
As for step 3, how do you install Magisk on the inactive slot?

Open magisk, click the first install option and download that zip. Then a box with four options should appear. Click the last option to install on another slot.

Thanks! Trying now!

No problem. Let me know if you have any issues.
Well, it's different (booting to TWRP instead of stock recovery), but it still didn't work. It booted through the "warning...unlocked bootloader" screen twice, then went to TWRP, though without encryption. I was able to switch the boot slot and get into system again (just as it was before the flash), but I don't know what I did wrong.
The only thing different I did was use the tools under EX Kernel Manager to flash the TWRP retention script, as I couldn't find where Magisk could do that.
**EDIT**
Now when I try to do the OTA, I get a "System update installation failed".
I cleared the cache and tried it again, this time doing the retention zip from inside Magisk > Modules > Add (+ sign) option, which is what I'm assuming you did.
It did the exact same thing. After step four, I rebooted, and it went straight into recovery (without the option to decrypt).
I think you have to root your phone again If you have the chinese twrp you can do it via twrp. Otherwise put tj magisk installer on a USB stick

I can install/uninstall Magisk all day long, now that I've put TWRP 3.3.1-30 on. Even after a failed update, where it fails to ask to decrypt, I can still sideload via USB and install it (even though I can't see the internal storage).

Can you lflash the ota image again? And after that twrp and after that magisk again. After that reboot to system again. This worked on my pixel. Not shure if this works on the 7 pro...
Maybe do some research first. There is also a unbrick thread

I've tried that... several times. I wish it worked.

I've been doing a lot of research. There are some pretty in-depth threads on reddit how the A/B treble system works. Nothing I didn't already know. It's certainly different than pre-treble, but not rocket science... something is wrong with the phone. I would just like to know what I did wrong in the first place so I don't do it again.
Fortunately, I still have a bootable system with root on my B partition, so I was able to run TB and backup everything, along with all my pictures and such. I'll be restoring it to stock and just going from there. Looks like I don't have any other choice.

Okay I updated just like we do with our pixels when we flash a custom ROM. TW RP flash your ota.zip,TWRP zip, reboot to recovery that will switch slots , because your update just flashed to the other slot, then flash magisk then reboot. That's how I did this last update. Oh and it's got to be the full ota from what I read anyways.
