Can a rooted phone be updated? If i root my razor, will i be able to update without re-rooting?

No, it fails to install. You need to reflash the stock boot image to take an OTA.
Confused still

I'm Sorry i'm so nooby in this regard.
So do you mean i have to basically get the stock ROM back again.
Then I can re-root like i did with the earlier version?

Yes. Razer's update engine doesn't seem to have the option to download full images like some other OEMs, so only fully stock ROM can be upgraded.
On that note, Razer seems to have set a week as the delay for releasing factory images, so if you want to keep root you might want to wait after an OTA, though we may be able to reproduce a slot earlier if someone captures the OTA package (but it's not as verifiable of course)

Not quite... The update will likely fail to apply due to checksum failures. If it did go through it would probably brick the kernel so that's a good thing. Sorry, there's not really a way to automatically root after official OTAs as they update block by block between two known states, and neither is rooted. It's just sort of not possible, by design. You have to unroot, update and root again.
The OTA package translucentfocus has provided allows us to reproduce a single slot before the week's wait for the factory image so we can root sooner.

Sorry, I didn't specify. It's the MR2 update for the Razer Phone 2. Original reply has been also updated with version information in bold.
How to update? Actually, I posted the OTA because it's really for someone to make a slot with root before Razer releases the Factory MR2 Images--as @CurtisMJ mentioned previously.

Sorry to bring back an old thread but just a few questions if you don't mind.
I just bought a used Razer 2 seems like the user rooted it (I was unaware) and it has been years since I rooted anything. I downloaded root checker and it said I was rooted. I assume I'm running the stock rom, though magisk manager was installed on the phone when I turned it on so I guess it's not stock. I guess this means I can not take any OTA or it could brick? I went into system update and it still checked to make sure I was up to date so maybe OTA isn't disabled? So much has changed with apps and rooting since I messed with it that I don't know enough and I don't want to brick or bootloop the device.
Thanks

Yes, that sounds about right. When rooted the OTA function doesn't disable right away. Only after its downloaded an update and actually tries to apply it it'll refuse. The new Android update engine is pretty good at not bricking. My guess is probably stock. If it's rooted, then the bootloader is unlocked, and it's not too bad. For magisk root at least all you need to do is flash the stock boot image and the OTA will apply. With factory images around and an unlocked bootloader you'll have a hard time bricking it. Just don't untick "OEM Unlocking" in developer options. Ever. (Or at least until you've fully restored stock firmware. It's supposed to be disabled so you can't make that mistake but Magisk hide tricks the firmware into believing the bootloader is locked so it's enabled. Whaddayagonnado)

Thanks for the detailed response I managed to get up with the previous owner on swappa last night. He told me he unlocked the phone but never actually got around to rooting it. He also said it is running stock and the reason magisk is still on the phone after a wipe is because magisk persists after a wipe.
Messages from him.
Sorry about that, I did unlock the bootloader but I never actually got around to rooting. I usually relock the bootloader before I sell it but I completely forgot. You can apply an ota because I never installed a custom recovery, something else I didn't get around to doing. You can easily relock the bootloader using adb. If you need help with this let me know and I can walk you through it. But the bootloader being unlocked has zero effect on ota's. You are all good to go as far as that goes.
Oh no you're absolutely fine with an ota. I just looked it up and you're absolutely right, magisk does survive a reboot now. Since I didn't load a custom recovery though an ota will install just fine. Although when an ota does install though it will most likely remove magisk because it will write over the boot.img with the factory one. Here is the link to the factory images. It includes instructions on how to install it. But honestly a new ota should be released any time now since the last one I think was November. Once that installs you will be completely back to stock.
Does this sound accurate to y'all. Thanks again
@Univsoldur His knowledge seems a little dated. Kind of how mine was a few months ago Anyways here goes:
If a root checker says it's rooted then it probably is. I'm not sure why he says it isn't.
Magisk does indeed persist through a data wipe. I wasn't aware magiskinit could unpack the manager APK though. Neat
He's right in that an unlocked bootloader won't affect OTAs, but having magisk installed will.
The RP2 uses the new A/B update scheme. In this case it doesn't matter whether a custom recovery was ever installed. Recovery mode is not used during the process of installation. Unfortunately the new update scheme is also heavily based on deltas, even on the kernel image, so OTAs will be broken as it won't be able to retrieve a full kernel image from the OTA servers. Some OEMs' ROMs can do that, but Razer's can't. You can flash the factory images if you truly want a clean start, but to fix OTAs and remove magisk, reflashing just the kernel image with one from the factory image should be sufficient. The magisk uninstaller won't work due to the data wipe so that's probably the only option.

Will that remove magisk and return it back to stock I would assume there is no threat of flashing the stock image. Besides that do I need to mess with the kernel?
I'm wondering if it would be possible to flash the unlocked Razer phone 2 firmware to the AT&T version. Would the bootloader need to be unlocked?

[Q] Having trouble figuring out rooting & recovery works on Moto X coming from Nexus
I'm no noob, I've been rooting for a while, but I can't figure out how to root this damn thing . On a Nexus, I just unlocked, flashed TWRP, then flashed superuser from TWRP, and I was done. How does it work on this phone? Can I just flash TWRP and then from TWRP flash a root zip? I'd rather not use any toolkits and such (which seem to be all the rage on this forum). Running Pure edition btw. On latest Lollipop OTA.

Yes its pretty much the same, the forums are abit immature at the moment there aernt any proper guides, i just did things the Nexus way
unlock your bootloader first through motorola, following the instructions (make sure there are no spaces in the unlock key): https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
flash twrp, then install the superSU zip from adb sideload or from your internal storage if it was already downloaded
youre done
also, you could flash the stock logo image to remove the warning boot image, http://forum.xda-developers.com/moto-x-2014/development/warning-message-unlocked-bootloader-t2871478 to make things look nicer

Awesome, thanks. Looks like that's what I'll end up doing. I really messed up my phone though when trying to get back to stock. Hopefully my stock image request will be approved soon and I'll be able to go through the process again.
One more question, if I kinda messed up restoring everything to 4.4.4, but I can boot the phone properly, will updating to 5.0 via an OTA update fix any mistakes I made along the way?

Not necessarily. The ota contains only changed files (not all files) and therefore if something is wrong with a file that wasn't changed (including anything in /data) then it will still be broken after the update.

Honestly, I haven't looked at what options are available for images to flash.
When I asked for firmware, I believe that I asked on a Friday evening and received access on the following Monday morning. So maybe you'll get access in another 15-16 hours? That is your safest bet if your phone is working well enough to last you until then.
Hello everyone,
I'm back to a nexus 6 after a very short stint with a 6+.
A little background for my questions: This is the very first time that I rooted a phone. I'm rooting to only install these 3 apps:
adaway
titanium backup
greenify
I do not plan on using any custom ROMs or kernels.
I see from all the guides and tutorials that people also create a custom recovery whenever they root. I haven't done that yet and wasn't sure if I had to. I would like to maintain the stock recovery that I have currently so that I can go back to stock if I unRoot. My questions are:
1. Am I wrong in thinking that I can still use the stock recovery if I unRoot?
2. When a new OTA comes out and I flash it (since I'm rooted an no longer can install them automatically), will that also upgrade my still stock recovery properly?
3. Following up on the previous question, when I upgrade manually because I'm rooted, would that be a fresh install where I have to go in and configure things the way I like them again (system settings, apps and their settings, root the phone again, etc)?
Thanks in advance!

1. No, you're not wrong. Recovery will stay stock and can be used normally
2. You can't simply flash the new OTA. This will not work manually nor automatically.
3. All you need to do is not flash the user data image and you will not loose your data, settings etc. You will loose root however. See bellow.
Google posts android stock images for each device typically before OTA hits your phone. That's what you want to grab and use for the update. Just make sure you don't run the automatic scripts that come with those images because you need to avoid flashing user data image.
OTA zip file does you no good unless you get your system back to unmodified stock.
Thank you sir!

Based on the OP, it sounds like he has only rooted. Thus, the OTA will work fine. No need to flash image files.
Edit: I see that at least one other member has stated that an unroot still did not allow OTAs to function. That's a bit strange and unique. Not sure what root is modifying to prevent the OTA.
I'm kinda curious myself. I had no idea root killed OTA's. Maybe I wouldn't have done that if I knew that. I'm very new to the Nexus device. It's my 1st. I unlocked the bootloader and rooted already.

This is pretty scary. So you can unroot and GI back to stock and still can't update in anyway?
I have always side-loaded OTAs, I have never flashed anything.
After installing an OTA, on the next reboot, Android takes some time to optimize all your apps. Does this also happen after flashing a new system image? Thanks!

not sure what you mean by GI, but according to some others, after uninstalling root via SuperSU an OTA will still not install. This should not be the case unless the boot or recovery images are modified. Easily fixed by following the procedures above to fastboot the stock images on your phone.

Root on Lollipop is not what it used to be. There are files that need to be modified in order to allow root. That's why this time OTA will fail if you are rooted.
Un-rooting however, will allow OTA as long as it is done properly and all traces are covered up and returned to stock. If it does fail after you have un-rooted, go back to the developer of that un-root method and let the know they missed something.
Here is the best way to un-root. Flash all of the old stock images besides user data image.

That makes sense. Is there a manual root procedure or list of required modifications for root out there? I did some precursors searches but Came up empty. Can't tell what's missing in SuperSU unroot without those details.

That's the problem with Chainfire's work... he does not release source.
Again, best un-root method is to flash original images less user data.

I'm afraid not but Chainfire's is probably the cleanest possible. Koush was the one with an open source solution but he hasn't updated his to 5.0 yet.

The base changes and reasoning for those changes are actually documented on my website. Specific policy adjustments are present in plain text in the supolicy executable, as any hex editor will show you. Those who really wanted to know rather than whine about OSS, know.
By far most policy adjustments just drop audit log output for contexts that are already permissive, though.
All that information is still completely useless unless you understand SELinux in detail and how it's implemented on Android, though.
I assume that the encryption doesn't get in the way of being able to flash the images?
When I went from 5.0 to 5.0.1 on my old Nexus 5 all I did was flash the two new 5.0.1 images I extracted from the full factory image, then re-rooted. This is far cleaner than reverting back to the previous image then doing an OTA. I've not had to update my N6 yet so I don't know if my method will work still, but I hope it does.

Thanks for the additional information.
I did spend a fair amount of time reading your documentation but failed to utilize a hex editor. I am not 'whining' about the lack of open source, rather, simply mildly surprised, but your website aptly describes the challenges with 5.0. Many are used to various root methods being available.
Your solution is fine with me.. I love your work.
Edit: I thought I'd add that the discussion has devolved from the OP, which was whether an OTA can be applied after uninstalling root. The answer was no, due to the unknowns about what still might be modified following the uninstall via SuperSU.
Usually when a new Android OS version is released, I'll just start over from scratch by manually flashing the seven image files using fastboot. I then install the unencrypt kernel/boot image and also root.
Now that these security updates are coming out every month, is there an easier way in my specific situation to install the update only without having to start from scratch every time like above?
Flash the system image only (if radio is different, flash that too). That won't overwrite your user data/apps
Edit: When flashing the system.img, flash the cache.img as well (to be safe)
Thanks. That is pretty simple. I wish I asked this a long time ago so I could avoided a lot of resetting EVERYTHING up all the time. 2 more clarifications if you don't mind...
1) Would this also work for point releases, like say if a 5.1.2 comes out, or would it be better to reflash everything in that case?
2) No other steps like clear cache or anything? Just flash those 2, reboot, and then I should be good to go?

Thanks. That is pretty simple. I wish I asked this a long time ago so I could avoided a lot of resetting EVERYTHING up all the time. 2 more clarifications if you don't mind...

It should work just fine for point releases. For major releases (like when Android M is released), I will probably flash everything, and wipe everything (including userdata), and start from scratch ! lol!
In theory, it should work find even for major releases, but I'd rather start with a clean slate - especially with the new permissions manager that is being added in this release. I'd rather not take any old incompatible apps thru' - but that's just me
Clearing cache is usually not needed. I've heard of instances where some users get stuck on the Google boot logo for some reason when booting for the first time. If that happens, clearing cache seems to help.
To be safe, it may be a good idea to flash the cache.img too. It takes a few seconds. Better safe than sorry. I'll update my earlier post.

Huge thanks. This should make things a lot easier for me.
Is this the system update that just got pushed to my phone? It looks like a small update, like 26MB?
Mine tried to install and failed. My phone is stock, latest official version, never rooted, but the bootloader is unlocked and it is running the no force encrypt kernel, which I believe is probably what is causing the issue?
Only way is to restore completely to stock, take the OTA and then install the no decrypt?
I got the OTA today to upgrade to M from L- (on verizon) where can I Find that system image to flash- I tried sideloading the OTA and it didn't take.

I believe it's actually both of these things causing the OTA not to take. If anything, anything is changed from stock...no OTA. Bootloader unlocked, kernel, root, even just changing the build.prop (but you need root for that) would cause it to fail. I believe it checks every file and if anything in /system has changed, no OTA.
I've never messed around with the encryption pieces, but I'm wondering if you only flash the system.img (you'd need to re-root) if that would suffice or not as far as the update. You'd be flashing the entire system file instead of only the delta the OTA provides, but it's probably worth looking into.
Hmmm... Well, it takes 15 minutes to just wipe the phone and flash the new ROM with the toolkit, install my apps, copy my files over and set the phone up, so it isn't a big deal, I just want to make sure that I have the right version before I do that...
(LMY48M) That's the one that I want for the VZW N6, right?
I just use helium to backup my apps and everything. Even if I need to wipe it is a pretty easy restore process. I highly recommend helium backup.

Unlocked bootloader doesn't affect it, the customised kernel does though . But yes, you could just flash the system.img
I have a Droid Turbo that is currently on version 5.1 (23.21.44) and I just recently unfroze the system update notifications for my phone because of the news of MM. I am currently rooted and have an unlocked bootloader but I don't have TWRP installed and would rather not install it for now if I don't have to.
The system update that it is trying to push to my phone isn't MM, instead it is version 23.21.49.en.US. Is it safe to just take this update while being rooted and with an unlocked bootloader? I'm also not sure how many updates I'll have to make my way through before reaching the MM update, but if there are other updates, should it also be safe to go ahead with those as well? I know I could install TWRP and flash the MM ROM that way but I would prefer to do the updates officially if it is not risking a bricked phone.
Thanks for any advice.

It's safe, but it will be unsuccessful until you unroot your phone and undo any other system modifications that you've done (xposed, for example). There's a huge part of the update script that checks every single file in your system partition to make sure nothing has been modified.
Ok great, thanks.
The only other modification I can think that I've made is enabling mobile Hotspot through editing a setting somewhere. Do you know if that would be affected or would need changed back?

You did that by modifying /system/build.prop. That change might be okay, but I would change it back if I were you just to be safe. The change is going to be overwritten anyway once the OTA is done.

It's possible it may miss overlooking that. The worst that could happen was the update just doesn't take. It fails and nothing is changed. There is a pure MM official version that you can Flash in TWRP. It will update everything, radios and all, but will not relock the bootloader. I recommend you download Titanium Backup and backup all of your apps and their data to be restored after the update. A factory reset is recommended after the update. Also, don't forget to back up all of your photos, documents, music, etc. 24.81.5 is MM. Your update was a prep for MM.
Thanks for the advice guys.
I didn't realize it but I had TWRP installed so I decided to flash a stock ROM and proceed with the OTA updates from there. The problem currently is that I'm being locked out of my phone because of the Google "verify your account" page. I reset my account password on that page and now I'm not able to log in.
So far I've been running my OP3T with stock rom with TWRP recovery and SuperSU to have root. This was mostly because I wanted the Adaway and titanium backup to work. I undid everything so I could update to the latest OxygenOS version, and now I'm on the stock recovery too, but with bootloader still unlocked I believe. I no longer have root after doing the upgrade as far as I can tell, still a bit new to all this flashing, haha. The last time I did this was when the nexus 4 came out
What is the best option for maintaining root while still being able to upgrade smoothly? I'm not against using one of the custom ROMs if that will help, but I do kinda like the stock rom so far!
thanks!

Thank you, I have seen that post. I'm guessing any route I go I'll have to flash updates then? I was hoping to find a way to be able to use OTA updates.
I've also never been able to get rid of the dm-verity error, even after going back to stock and locking the bootloader. Is there anything I need to worry about with that or is it just an annoyance?

Dm-verity u can bypass but bootloader one, you can not. Look at the apps, mods section.

You shouldn't try to flash the partial OTAs while you are rooted and have a custom recovery installed. The partial zip will try to make specific changes in the restricted partitions (/system, /boot, /recovery, etc.) related to the update and prior modifications to these files may cause the update to fail and the phone to brick. You can still use the "Update" tab in the Settings menu to download the update though as OOS will detect root and download the full zip of the update for you. Simply flash the full zip in TWRP, wipe cache/dalvik, then flash SuperSU and you're good to go the next time an update rolls out. Updating by this method (rooting immedately after flashing update) will also prevent OOS from replacing TWRP with the stock recovery again. When you download the update, you'll know if it's the full zip if the file is >1 GB (they're usually ~1.4 GB,, whereas the partial zips are a few hundred MB).
Unlocked bootloader warning screen is cannot be removed without relocked and fully resetting (wiping) the phone. DM-verity warning screen can be removed by following this guide. Make sure that you are flashing the correct firmware for you current version of OOS though, flashing the wrong version can brick you phone.
