No you can't take an OTA if you have any modifications to /system (root). Have a look at my guide:

I got an 8MB update for the november patch. Being on TWRP and root i need to convert back to stock before i can have it leave me alone? Is there a way to flash the patch without doing that?
Thanks for answering my question

No way around it, any modifications will cause the update to fail.

@amoeller had me flash the modified boot.img for MDB08M then flash the MDB08M system.img and vendor.img from the factory image. I rebooted bootloader, the booted to TWRP and re-flashed supersu. I am now on the November patch without having to remove TWRP and all works well. My user data was also untouched.

User data should never be affected during an OTA anyway.
This is actually the first time I've unlocked a phones bootloader and stuck with the stock rom. I usually use some kind of popular rom with it's own built in OTA (CM/Viper One)
How often do you guys actually update your phones for OTA? It seems like a real hassle

I am rooted now so I'll wait a while before updating an ota until there's a big deal of info. However, in the past if I was sticking with stock there's usually at least one developer who posts the updates with root and stuff built in so you can easily flash with twrp. So I'm kind of waiting for that. That or cataclysm or another awesome rom that's close to stock.

I wait for factory image for that build and flash over the new images when they become available (provided that root can still be achieved). Some will do a clean wipe and start fresh with the new build and reload in their apps and user data, others will just dirty flash the updated system (and boot/bootloader or whatever else was changed too).
If you think about it, it really isn't all that different from taking an OTA, the difference is that we're applying the commands to flash instead of having it automated. It's not that big of a trade off in my book.
I have 2 questions...
What is the easiest way to make flashing updates a breeze if I have mods in /system partition? I have heard of "freezing" them. Or is the only option... to delete every mod and flash updates? If so, should I keep a note of every change I make to/system?
And last... Should I make a backup of any file i am replacing or overwriting in /system? And if so, do I have to put them back how they were before flashing an update?

If you're rooted then you need to download the full factory image, extract system and vendor and flash those. Reflash SuperSU.

It’s probably easier and quicker just to flash stock factory images separately instead of having to jump through hoops with OTAs. Like I told @roughriduz just flash the updated partition(s) that were updated like system.img, vendor.img, or whatever and just flash SuperSU in TWRP after.
The steps @roughriduz took was
1. Download and extract latest factory image.
2. Download matching modified boot.img for that build (For example MDB08M).
3. Flash system, vendor, and any other partitions (like radios, etc) with fastboot if they were updated in the OTA. Don’t bother to flash stock recovery because we’re not using an OTA. Flashing userdata.img is just like a factory reset.
4. Boot directly into TWRP and flash SuperSU.
5. Reboot and profit.
This method gives you the latest stock build rooted with TWRP while keeping your data because I hate having to redo my phone.

A couple questions:
1. Step 1 refers to the latest factory image that contains the update, correct?
2. Step two refers to the boot.img that contains root?
3. At what point in this process do you flash the modified boot.img, before or after applying the other images?
Thanks for your help!

1. Latest factory image is the latest factory image from the nexus factory images page. It's not an update like ota, but rather the entire image they would return you to stock if all is flashed.
2. Flashing a modified boot does not give you root. You still have to flash SU, so saying the modified boot contains root isn't right.
3. I flash boot first unless there is an updated bootloader.

1. This can be whatever the latest factory image is at the moment. It’s currently MDB08M. All the OTA does is update your phone to whatever build it was made for. Factory images already have previously released updates built into them. You can upgrade but avoid downgrading unless you want to factory reset your phone.
2. I’m referring to the boot.img without root by @mrRobinson found https://www.androidfilehost.com/?fid=24269982086992320 although this process can be used for systemless root also. For systemless root you wouldn’t flash SuperSU in TWRP but instead sideload the SuperSU APK as per Chainfire’s instructions and use the matching systemless root boot.img
3. I don’t think it matters but as long as you have the matching modified boot.img with the system.img installed before you restart, you should be fine.

What the heck did I do wrong here? I just tried to apply the November OTA update to my MBD08K build, it didn't work, and now I am in the process of doing a full reset and rebuild of my phone (flash-all of factory images from Google)
Here are the notes I made as I attempted to follow the procedure in this thread:
Code:
- Download latest build for MBD08K from https://developers.google.com/android/nexus/images?hl=en
- Extract boot.img, system.img, vendor.img to C:\adb (or wherever where adb and fastboot are
installed). You have to
- Right-click, open command window here
- Ensure USB debugging is enabled on phone (grant permissions on phone if you get the popup)
- In command prompt, "adb devices"
- Should see serial number and "device"
- type "adb reboot bootloader"
- Should get to bootloader screen with little android man lying down with hatch open
- type "fastboot devices" - should see your serial # again and "fastboot" beside it.
- type "fastboot flash boot boot.img"
- type "fastboot flash system system.img"
- type "fastboot flash vendor vendor.img"
- Use volume keys to boot into recovery (in my case TWRP)
- Swipe to allow modifications
- Install -> SuperSU.zip that you should have on your phone from last time.
- Reboot system
I saw a red "your phone is corrupt" scary message on startup... took a while to boot. Couldn't get past the dancing circles.
Interrupted boot, rebooted to fastboot, tried to flash old modified boot.img
Booted again, got encryption unsuccessful warning
Flashed most recent boot.img again, stuck booting forever
try again:
- flash system.img
- flash vendor.img
- flash boot.img (modified)
reboot to recovery - your device can't be checked for corruption (yellow warning instead of red)
- swipe to allow modifications
- reboot with TWRP, swipe to install SuperSU
- Encryption unsuccessful. Prompt to factory reset. Click OK. Boots through TWRP.
Give up, start flashing factory images.
EDIT: I might be the stupidest person alive. I think I should have been using the files for MDB08M. Arggghhhh. Someone please confirm I am an idiot.
Edit 2: Factory reset worked, I am at MDB08M. Now rooting again... grr. At least I backed up all my apps & settings to Google Drive with TB.
Edit 3: Rooted and restoring all apps with TB. If anyone has any insight into where I F'ed up I'd appreciate it.
Hello,
I am just new with Samsung smartphones, previously I was on some other devices such Nexus which are easier to mod.
I would like to tweak the kernel( I already got the sources) to add few things but I need for that eventually the ramdisk and the kernel image to make a boot image.
I wanted to download the latest firmware, hoping a default boot image was integrated in it and that I could unpack but I got issue and connection loss so I can't even take a look at it.
I think I will be able to get the boot image with the dd command but to do so I need to be in a mod recovery(such twrp) and currently I can't.
Thx u
Firstly you've created a voting thread. If this is a standard question I suggest in future you leave the options at default.
Why can't you use TWRP?
My build also supports raw image backup of the boot partition.
Sorry about creating wrong thread type
I have extended this feature to include BOOT
Click to expand...
Click to collapse
Woot Yeah I didn't know about that!
So I can just get the current boot image, unpack it, replace with my kernel image, repack and done.
And then flash the boot image throw a zip install or your extended function.
Btw, I am was looking over the net but couldn't find an exact answer to this extra Q, is there any fastboot mode ? So I can just boot in a custom kernel image before flashing it.
Yep, just backup the boot partition using twrp.
Locate the boot image backup in the twrp backup folder.
Unpack it, make your mods, rename it boot.img, copy it to internal or external storage and flash it with TWRP using the INSTALL button.
Samsung devices dont have a fastboot mode.
@ashyx answered my questions, thx to him!
>Samsung devices dont have a fastboot mode.
My latest Samsung Tablet has a fastboot mode but it was manufactured around the end of 2012 ... So it is not quite recent
I've never known a Samsung device to use FASTBOOT, so that's news to me.
Samsung uses its own proprietary ODIN mode.
Which device is this?
Ahhah you gonna say I am half of a lier.
It was my nexus 10. Built by Samsung and running the 5250 exynos chip
Hi all, I posted this in the 6P bootloop thread, but didn't get a response. As that is a pretty LONG thread, i'm thinking my question may have gotten lost in the jumble.
Quick run down.
A few months back my 6P started the BLOD. I found the fix listed on these pages, applied it, and have been happily using my phone ever since. Phone is bone stock 7.1.2 other than the TWRP recovery and the modified EX kernel for 4 cores.
Since the fix, my phone FINALLY got the OTA update to go to Android 8.0 and i obviously want to get it done. My concern is HOW to do this without causing more headache.
Can anyone point me in the right direction? Should i use the OTA update or download the factory image from Google?
I've got some knowledge as i used to be into the "rooting" scene back in the day, but haven't for a while, so i feel a little lost.
Thanks for any help.

Well, for starters do NOT take the OTA. It will either fail or boot loop your phone. Due to the fact you have a modified boot.img you will need to update manually using fastboot with the full image. Re-apply the modified kernel after you finish updating the partitions, but BEFORE booting the first time. You can follow most guides on how to manually update a full image using fastboot, just add the step of flashing the modified kernel before booting.
Thanks for the reply and the help. If i could ask for a little more help, as this is my only phone.
Can you explain the difference between the modified boot.img and the modified kernel?
If i download the factory image from here (https://developers.google.com/android/images) is it ok to the get the latested one (Nov 2017) or do i need to get the original one (Sep 2017 as i'm on Fi)
Once i flash the factory image, is it going to replace the modified boot image as well as the modified kernel?
Follow the OP on this thread (https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279) in the downloads section there appear to be 2 files i would need, the "Boot.img from stock 6.17, 8.0 firmware" and "EX kernel version 5.03". Am i understanding that correctly?
Like i said, this is my only phone, and i'm probably just being overly paranoid about bricking it, but any clarification would be greatly appreciated.

Use the latest November image. The boot.img contains the kernel and ramdisk, critical files necessary to load the device before the filesystem can be mounted. When you flash the new boot.img contained in the Google image, it will overwrite the patched kernel. You then need to re-patch it by installing EX kernel before booting. EX writes to (modifies) the stock boot.img. There are also pre-modifed boot.img files floating around. You will probably get more detailed help in the dedicated thread. Learning to flash manually (or remember how) is not really a big deal and a necessary skill for modding (and for getting yourself out of trouble). Good luck. :good:

Ok, so 1 last time (sorry)
1 - Downloaded the latest 8.0.0 factory image from google (this contains the bootloader, radio, and partitions (.zip).
2 - Get phone to fastboot and apply the above 3 new images
3- before rebooting, flash oreo4core (new, modified boot.img), TWRP recovery.img
4- reboot to recovery (TWRP) and apply the modified EX kernel
5 - reboot and (hopefully) profit
Am i missing anything, or doing anything that isn't needed?

<<Disclaimer: I don't use the 4 core kernel, so I don't know if it comes with installer script or someone has just modified the latest boot.img>> Unzip the "partitions" zip you refer to and extract those image files to the same folder as bootloader and modem. For example, you can keep TWRP recovery if you don't flash the recovery.img. That is how you preserve your custom recovery. So in other words you'll now have a folder (your ADB folder?) with 5 image files.... bootloader, radio, boot, system, and vendor all in one folder. <<Note: it is my understanding you just substitute the latest oreo4core file (should be boot.img?) If this is true, copy that file into your ADB folder and let it overwrite the stock boot.img. Stop. Copy over flash-all.bat, change the *.bat extension to *.txt and open in notepad. You will see (and can copy/paste) the fastboot commands to get you started with bootloader and radio. Then flash the last 3 (boot, system, vendor). At this point you can reboot into the OS. Since you substituted the oreo4core boot.img file for the stock boot.img there is no need to use TWRP to flash anything. That and since you skipped flashing the recovery.img, TWRP is still there.

Thank for the help! Everything seems to be up and running. I know you said you don't use the "4 cores" (can only assume your either on a different phone or yours isn't affected by the BLOD), but do you know if i still need to apply the EX kernel update, or know of a way to tell if it's already been applied?
Thanks again for all the help. I was pretty much in the right direction, but being as how i'd been away from it for a while, i wanted some backup

I don't think you can flash EX kernel from now on. I think you have to use a modded boot.img that will contain his kernel/ramdisk. This is my guess. You really should be getting your information in the dedicated thread where everyone is actually installing and using it. Google "oreo 4 core" and you will find the XDA thread is the first hit. Good luck. :good:

If u are sure that u haven't touched the system partition then u can try to update via OTA. Make sure u flashed and not only booted the downloaded boot.img from V9.6.4.0 ROM. I guess it's better to download the latest version from here:
https://drive.google.com/drive/mobile/folders/1dw87qgRNGxfj7UZduHK91LE6X1Xs7CWL
Then do a clean flash and install the entire ROM with fastboot.

I've done flashing while on the way and I'm waiting. My cellphone suddenly turns on and it looks like it's doing a factory format. and I just updated it to August. all my data is lost even though the user data has been secured and the flashing process has not finished
Hey all, just wanted to try and combine the bits and pieces of the "how to update OTA for rooted/BL unlocked" phones into one place as a quick run down for myself (and others who might have the same question) for the OTA:
Grab OTA update manually
Uninstall Edge Sense Mod from Magisk
Plug in phone into PC
adb reboot recovery
adb fastboot flash "stock boot.img"
adb sideload "OTA file name"
Reboot to bootloader using the volume and power button
adb fastboot flash "patched image to inactive slot (no idea how yet, sorry! Will add command)"
Reboot phone
Go back into Magisk and install manager for root
Re-install Edge Sense Mod within Magisk
*Optional*Re-apply Magisk Hide
Please let me know if there's any steps I'm missing or how it could be made easier for others to understand and if there's credit(s) missing (10+ hr shift and running on strong tea only 11 hr shift arguing with doctors to actually provide care instead of leeching insurance, and insurance to pay the damn medical claims instead of baton passing them to patients).
Disclaimer:
I'm no developer, just a common user that wants to make it a bit more convenient for other Pixel 3a owners to OTA update while rooted/BL unlocked. If it didn't work, or you encountered error(s), let me know and I can link them in so others can learn.
Disclaimer 2:
The above step(s) is assuming you've used pbanj's method for getting Magisk. Apparently I should add this as there's the "conventional" and "unconventional" method for Magisk. Had no idea since there was no guide available informing people otherwise at the time of making this step-by-step guide.

Before step 5, you need to fastboot flash stock boot.img before doing "adb sideload ota file".
I think step 7 should specify flashing patched image to inactive slot, (a or b), so as to be on the new active slot after a reboot, (step 8).

I followed the op procedure and it worked without flashing the stock boot image. To what slot would you flash the stock image, active slot or inactive slot? Can it be flashed to old slot after step 8 reboot? Would there be any benefit?
I'm not sure why people insist that using the "modified" boot images make the update process faster or easier..... I assure you it does not.
Here is the update process if you install Magisk the normal way......
- Magisk: Click “Uninstall” → “restore images” → NO REBOOT
- Download and install OTA → NO REBOOT
- Clear all apps from recents (probably not even needed, but better to be safe than sorry).
- Magisk: Click “Install” → “Install to second/inactive slot (After OTA)”
- Reboot
That's all......... and it's all done from the phone. No computer or ADB is required for updates.
Tell me how that is harder than your method or how your method saves "a MASSIVE amount of time"?????
Look, I'll be the first to admit that using the modified boot images does make the initial root process easier and faster - by a few steps and about 2 minutes of time. But you will pay for it when it comes time to update your phone.

Forgive me sic0048. You helped me in another post but I feared doing the initial step, magisk-uninstall-restore images. My reading of these forums indicates there is no stock image to restore since it was overwritten by the patched image during the initial root process. It is the transition from using patched images to doing a normal Magisk install that I lack knowledge of.

Great point, difference between downloading a patched boot image vs patching yourself is not clear as to how it affects the OTA update...

I totally understand the confusion......
If you use normal Magisk installation method where you let Magisk modify the stock boot.img file, then the OTA update method that I described above should work. Because you let Magisk modify the stock boot image, it will be able to use the stock image in the first step - Magisk: Click “Uninstall” → “restore images” → NO REBOOT
If you used the "modified boot image" method, you were able to skip the step where you let Magisk modify the stock boot image. This saves time initially, but it comes back to bit you during an OTA update because Magisk is unable to use the stock image to uninstall itself. You are correct that the normal Magisk "How to Take an OTA Update" instructions will fail if you used the modified boot image to gain root initially.
I guess I didn't realize that you had used the "modified boot image" method. Here is my recommendation to all those that have used the modified boot image method - start over.........
- use the Magisk manager app to Uninstall Magisk using the "Complete Uninstall" method.
- Pull the stock boot.img from the applicable factory image (whatever OS version/update you are currently on). Downloads are available here https://developers.google.com/android/images
- Using your computer, flash the stock boot.img file by using the command "fastboot flash boot boot.img"
- Reinstall Magisk using the "normal" method....
- Put the stock boot.img file on your phone's root SD card location
- Use the Magisk manager app to modify the stock boot.img
- move the magisk_modified boot image to your computer
- flash the magisk_modified boot image to the boot partition using the command "fastboot flash boot <patched_boot.img file name>"
- reboot
Then follow the instructions I gave for the normal OTA update process listed a couple posts above.

Unless I'm misunderstanding the process, seems like Magisk is missing a checkbox to backup the unpatched boot image prior to creating a patched image, for future OTA updates...

Magisk isn't missing this option, it's just that the method suggested by pbanj in this thread bypasses the normal method. It's not an issue with Magisk, it's an issue with the root method being suggested.
What I really need to do is create another "How to Root" thread and list the normal and recommended method. The confusion comes from people coming to this site and reading pbanj's thread and thinking that is the correct way to root. It is not the correct way to root.

Normally you would flash the stock boot image to the active slot to unroot the phone prior to installing the OTA.
Confused as to why flashing stock boot is no longer necessary. If this works as stated, it would appear the OTA is no longer patching the phone's boot and system partitions as had been done in the past. So perhaps the OTA now installs full boot and system images?

If that is indeed the case we should be able to just install the OTA normally through the system update button without having to uninstall Magisk and get rid of root first. Then as the Magisk tutorial states cancel the reboot go into the Magisk manager and reroot. Has anyone tried this on a rooted phone?

I had read, but have not confirmed myself, that the OTA images did include the boot and system img. However I just checked and the factory image for the June update on Bonito is 1.6gb while the "full OTA" image is only 1.1gb. So the two images are not identical. It's not like you saving a bunch of time by not uninstalling Magisk first and I don't think I would skip this simple step with the hope it would work. I'll continue to follow the recommended procedure that the Magisk developer has come up with and I would recommend to others that they do the same.

It's smaller as the OTA only contains the partitions that have changed such as system and boot. The other partitions are probably cloned over from the active slot to the inactive slot.
As I mentioned previously, the Magisk tutorial does not account for not having a backup of the stock boot image when you download the patched boot, so to remove boot prior to installing the OTA, you must manually flash the stock boot.

Before step 5, flash stock boot.img to slot a (or just use getvar to get the current active slot. It should be slot a before first ota). If you don't flash stock boot img, you will get error message "E: Failed to verify package compatibility".
I think you didn't get this message because you actually restored stock boot.img when you uninstalled magisk. For those who rooted their phone by flashing patched boot.img, magisk doesn't know the location of stock boot.img.
Then in step 7, flash patched boot.img to slot b (after ota, the active changes to slot b. If there is new ota in the future, just use getvar to find out the active slot)

Thanks to all, was not expecting this much reply in this short amount of time, at all.
I made this step by step guide because no dedicated thread really was readily accessible in one place. Hopefully this inspires others to make guides.

How else could the phone have been rooted besides flashing a patched boot image on a device without a custom recovery, such that Magisk on his device knows where to find the stock boot image?

Learn how to read a few posts in this thread.
Root method 1: install magisk, patch the stock boot image, then flash the patched boot image to gain root. Magisk knows where the stock boot image is. In this case, just follow the instructions to take ota: uninstall magisk to restore stock boot image and take ota, then reroot.
Root method 2: flash patched boot image provided by someone in the forum, then install magisk to get root. In this case Magisk doesn't have a backuped stock boot image. So the regular instructions of uninstalling Magisk to restore stock boot image doesn't work and you need to manually flash stock boot image to take ota.

Difference is downloading the patched image vs patching it yourself. Wasn't clear how that created the issue. Well written, thx for pointing it out.
So if anyone patches the new version boot image before uninstalling Magisk, they'll get an error. Likewise, patching the current boot image in the manager will allow the uninstall to work correctly...

you dont need to restore stock to update. the restore is only needed if you want the phone to handle the update. if you sideload the ota in adb it updates fine then you can just flash the new patched boot image. also fun little fact, even if you use the pre-patched images you can still use magisk's internal update method. you just have to do one simple thing....... grab the stock boot.img for your current update, and tell magisk to patch it, it will create the stock backup and then you can just use the magisk update method. i've been meaning to add that to my thread but i've been busy and having some health problems so i haven't been on here in a few days.

Sorry for the health issues. Take care and get well soon.
Thank you for this post. I was getting confused about the ADB sideload of OTA (which, iirc, didn't work on unlocked BL on my last phone), which you said does work on the 3a. My last phone was the N5X and despite Magisk being available, I stayed with SuperSu (which worked for me as well as suhide and FlashFire). The dual slot is new to me; I think my MOTO Z3 Play has that (I'm not unlocking that one atm) so it really doesn't matter.
If I fastboot flashed the patched boot.img to slot_b, then the next time I flash any boot.img, I will have to direct it to slot_a [fastboot flash boot_a boot.img]? I guess I'll learn as I go along. Next, I'll take current stock boot.img and tell magisk to patch it.

ya pretty much. every time the phone updates the active slot changes. I'm currently updating my root thread so everything is clearer and in one place.

Just to be sure, sideloading bypasses the OTA package compatibility verification that would give an error during normal update if it detects wrong boot version?
