[GUIDE] Nexus 7 (2012) factory image w/root

I know a couple people asked for a guide and I didn't see anything concise had been posted (Mods feel free to remove if it's a duplicate.). Things are still a bit fresh, but this should be a short list of steps to perform the upgrade of your Nexus 7 (2012) WiFi to Lollipop.
As with other guides, I make no expressed or implied warranties - you break it, it's on you.
This is how I was able to get Lollipop working on my own Nexus 7 (2012). I was coming from a rooted factory image of 4.4.4.4 which was the previous most-recent factory image released by Google for this device. I like my device as bone stock as possible and wanted to upgrade and keep it that way.
I assume the following:
You know how to use both adb and fastboot and have already configured your system to use these utilities.
You have already performed an oem unlock on your device.
That out of the way, on to the guide...
It goes without saying, but I'll call it out anyway... Take a backup of your current device setup. Most likely this is within your custom recovery or TiBu. If your not familiar with how to do so, consult the help pages for those apps.
Download & unpack the requisite files
LRX21P factory image from Google.
CF-Auto-Root from Chainfire.
OPTIONAL Only if you're upgrading from a version of Android prior to the JWR66Y Android 4.3 factory image, download the KRT16S factory image from Google.
Start by rebooting your device to the bootloader.
Code:
$ adb reboot bootloader
OPTIONAL If you have ignored my assumption and haven't already done so, now would be the time to oem unlock the bootloader
Code:
$ fastboot oem unlock
Run the following commands to prep your device to install Android L. NOTE:This will erase your device
Code:
$ fastboot erase cache
$ fastboot erase recovery
$ fastboot erase system
$ fastboot erase userdata
OPTIONAL If you are upgrading from a version of Android prior to the 4.23 bootloader release which was originally released along with the Android 4.3 JWR66Y factory image, then you will need to upgrade the bootloader also. The bootloader included in the Android L factory image is not correct and will fail to install. Your best bet is to download the KRT16S factory image from Google and use the bootloader-grouper-4.23.img file from that factory image. Be sure whatever version of the bootloader-grouper-4.23.img file you use has the correct md5sum.
Code:
$ md5sum nakasi-krt16s/bootloader-grouper-4.23.img
df53028033c9eccf4fe5ba7bc198ce24 nakasi-krt16s/bootloader-grouper-4.23.img
$ fastboot erase boot
$ fastboot flash bootloader nakasi-krt16s/bootloader-grouper-4.23.img
Now, install the actual Android L system
Code:
$ fastboot -w update image-nakasi-lrx21p.zip
Your device will automatically reboot at this point and when it does, you will be running Android L (5.0) 100% stock and WITHOUT ROOT. This boot usually takes a very long time (~5-10 minutes) as it's performing the initial setup of the OS. When the device is back up fully, you will have to go through the setup steps as if it were a new device. Once that's done, proceed to the next step.
Now that Android L is freshly-installed, not only have you lost root, but you've also lost the Developer Options menu and the USB Debugging option contained therein. So, before we proceed, we need to enable Developer options & USB Debugging in the settings menu so that adb & fastboot will work recognize the device. Again, if you have any experience with running adb & fastboot, you will know how to do this. The process is exactly the same as with previous versions, so there should not be any surprises here.
Go to the Settings menu and scroll down to and tap on "About Tablet"
On the next screen tap on the "Build Number" field seven (7) times and you'll be presented with a message of "You're now a Developer!"
Hit the back "triangle" and go into the Developer Options menu and turn on USB Debugging.
Just be sure to accept the key on your device when you connect it to your computer.
Now, we can use adb to reboot the device so we can apply the CF-Auto-Root patches and SuperSU from the bootloader
Code:
$ adb reboot bootloader
Once in the bootloader you will need to apply the cf-auto-root. Use the following command.
Code:
$ fastboot boot image/CF-Auto-Root-grouper-nakasi-nexus7.img
NOTE: Windows users have reported that the file is in the same directory so just double-check the path to the file.
This will boot the device onto a custom kernel, install the kernel fix to allow root and also install the latest beta version of SuperSU (2.20) for Android L.
You will now end up with a device running Android L with root. I did not mention at any point about installing a custom recovery. These steps will remove a custom recovery, so if you want to install that, you will need to consult the instructions for your custom recovery of choice. I usually use the CM instructions for installing CWM as they're easy to find. This is not strictly necessary for root. Similarly, my main purpose for rooting was to use Titanium Backup. The current production version of TiBu doesn't support Android L, but the TiBu team has released a test version for L via their twitter feed. Here's a direct link or you can go to their twitter feed for more info...
Questions? Comments? Did I miss something? Let me know.
EDIT: Seems that the performance has really gone down over the past few days. Not really sure what the cause of the performance degradation is but it's quite severe. I noticed last night after having left it plugged in all night that the device wouldn't even turn on or took an inordinately long amount of time (many minutes) to wake from sleep. As it stands I attempted to play a game that's slightly intensive and after a short period of time the device got really hot and started really having performance issues to the point where it rebooted on it's own. Further, I noticed a number of things aren't working that probably should... Bluetooth & "Battery Saver" mode are the first two that come to mind.
Anyone else experiencing similar issues?

worked for me, with 2 changes:
- I had to enable developer mode on my first boot into L before I could execute the command "adb reboot bootloader"
- on my Windows machine, I had unzipped the root zip file, so I executed the command this way: "fastboot boot CF-Auto-Root-grouper-nakasi-nexus7.img", leaving out the "image/"
Thanks for your guide!

SuperSU is there. It does not complain about the binary. But TitaniumBackup can't find SU...
EDIT: Found the solution for TB in another thread.

Would you mind pointing me to it?

If you're like me and haven't updated your bootloader to 4.23 you will need to do so... sadly that which is included with the most recent files is corrupt (yes the files from google.) download the krt16s version and overwrite your bootloader-grouper-4.23.img file. Then from the command line like before type "fastboot flash bootloader bootloader-grouper-4.23.img" then "fastboot reboot-bootloader" and follow the directions above!
Enjoy!

Not sure about on Windows, but on Linux when I unzipped the root zip file, there was a directory layout as such...
Code:
cf-auto-root/
cf-auto-root/image/
cf-auto-root/image/CF-Auto-Root-grouper-nakasi-nexus7.img
cf-auto-root/root-linux.sh
cf-auto-root/root-mac.sh
cf-auto-root/root-windows.bat
cf-auto-root/tools/
cf-auto-root/tools/AdbWinApi.dll
cf-auto-root/tools/AdbWinUsbApi.dll
cf-auto-root/tools/fastboot-linux
cf-auto-root/tools/fastboot-mac
cf-auto-root/tools/fastboot-windows.exe
In any case, you were able to find it. Should be pretty obvious which file I'm referring to...

Yes!
I needed my root. (The stock kernel underclocks like crazy, making the tablet nearly unusable.)

Thanks for the guide brother. You are awesome
I am now on a Rooted Android L tablet, thanks to the CF-Root 'boot.img' by Chainfire.
I have a question though. I wanted to ask ... this specific boot.img by chainfire seems to have automatically upgraded my SuperSU app to v2.20, so i didn't flash the 2.19 BETA. How did this happen? Any idea? (Did that CF-Root get updated after you made this guide?) i am curious to know

A very very very very usefull guide!!!!
All working fine!!!!
Thanks!!!!!!!

OMG corrupted bootloader AGAIN.
GOOGLE what's wrong with you???

Thanks for the guide! Works fantastically on my aging N7.

Does it wipe internal storage?

I made a mistake on the version number that I listed in my instructions. When I did my N7, I had originally just tried flashing SuperSU via the standard zip file method. The most recent version of SuperSU available in the SuperSU XDA thread is/was 2.19, so I just assumed that it was the same version being used in the CF-Auto-Root. But as you correctly point out, the process installs 2.20 not 2.19. I updated the version number in the guide. Thanks.

Yes, unfortunately it does.
I wouldn't recommend trying to upgrade without wiping user data. There may be internal changes to the file system and layout that could make a Kit Kat install (4.4.X) incompatible with this. Best to save off your data and start from scratch.

Hi. Good job on the guide. Very detailed. That's good.
Thanks for the tip with booting CFautoroot img. I was wandering why superSU 2.16 was not working and was looking for modified karnel all morning.
BTW. I know it's not recommended, even my Tapatalk signature says it
but I didn't wipe user data while upgrading. See my post here with details.
The Answer to The Ultimate Question of Life, the Universe, and Everything is: CLEAN FLASH.

Can I just ask about the bootloader?
I'm seeing alot of users reporting there's an issue within the bootloader that is included on the LRX21P image for Grouper, I performed a clean flash yesterday and flashed the leaked image for grouper, I haven't had any single issue flashing all of the images, even bootloader that came from the lollipop image doesn't seem to cause an issue.
Btw, everyone's suggesting to flash the bootloader from JB & KK on this lollipop build, is there any impact on the performance of why's that recommended to flash the old bootloader?
And I didn't really expect this but lollipop made it worst to run on this device! Even if it's a 2012 device, why's that it can't handle lollipop smoothly? I can't even drop the status bar down at a rate of 60fps as promised by Google, can't even swipe the screen smoothly and it's freezing as hell! It feels like something's wrong with this build.
We can't always tell the reason that this is a very old device so that it performs really bad, how come that my 2011 device with a CM11 installed that is still functioning well and smoothly performing operations on just top of its single core 1Ghz and 512 megabytes of RAM? Rather than this quad core tegra device that is WAY MORE faster supposedly?

Because Asus used chip silicon chips as requested by Google to bring the cost down. They degrade with time and slow down. My wife's 32GB Grouper is unusable in my standards (using Nexus 5 for list year and OnePlus One now), it lags as hell no matter what, F2FS or ext4, stock or custom ROM, it lags. I so much regret I didn't convince her to change it to N7 2013 last year, as she didn't feel the need to spend money...
I was so looking forward to N9, but not for the price they ask. 16GB is useless, so 32GB is the only option, but 489 EUR (=610 USD) they ask in Europe is way over what I'd spend on YouTube player (that's what she most uses it for) with, wait, wrong screen aspect to watch videos!

Yup, I all agree of what have you said. I tried ext4, f2fs etc etc, none of them improves the N7's performance or at least the stock one has the best performance and stability for me.
Heard alot of users blaiming about the tegra chip for this, they said that tegra chips are getting worst every year and if all of these are true, I have doubts about Nexus 9's performance since even the one of the famous 'Android Police' senior editors have found that there are unusual freezes and glitches from the device itself, idk if that happened on the latest build for N9.
The 2011 device I'm currently comparing to is an Xperia Mini, snapdragon chip with 1Ghz single core, 512MB of RAM, I'll look away from tegra based devices...
Btw, do you have an N7 2013? I'm planning to buy one this December to replace my 2011 device. Can I trust this 2013 model with snapdragon processor? I always trust these snapdragon based devices.

N6 5.1 assistance

I just bought a sim unlocked Nexus 6 from Amazon about a week ago and I need some help with it.... I guess I jumped the gun without gathering enough info on the N6
As soon as it was delivered I checked it out and found it had 5.0 on it.... I was unaware that there were two updates for it that increase battery life among other improvements, 5.1 and 5.1.1
( I had it search for updates 5 minutes out of the box, it said it was up to date, so I assumed it was)
So I rooted it and unlocked the bootloader and installed TWRP... I used it for several days to find the battery didn't last much past 3pm so I started researching battery issues on the N6 to find out that there are two updates for my N6 that resolve the battery issue.
So tonight I set out to try and get the 5.1 or 5.1.1 on it for the better battery life in the new updates. That's when I discovered that rooted, it won't get any ota updates...
So after reading countless posts and watching videos on trying to get the updates on a rooted N6, I installed Scotts 5.1 Rooted DeOdex Rom
HTML:
http://www.scottsroms.com/downloads.php?do=file&id=604
which is supposed to put me into a rom with the better battery life update.........
So now that 5.1 is installed I keep getting a pop up a notification that an update it available (5.1.1), I downloaded it on my phone and followed the prompts to "reboot and install"
when it reboots is goes into TWRP but I get an error message that the update failed..... So I am not sure how to install this 5.1.1 update OR if it is entirely necessary.
The error message in TWRP is as follows: "Package expects build fingerprint of google/shamu/shamu:5.1/LMY47D:user/release/keys; This device has google/omni-shamu:5.0.2/LRX22G/4:eng/test-keys.
Error executing updater binary in zip '/cache/updater.zip' E:Error installing zip file '/cache/update.zip'
Could somebody please shed some light on this for me.... I have spent hours here trying to figure this out to no avail....
Thank you
(Please don't beat me up to bad....I like to completely unlock my devices when I get a new one but I don't do this stuff very often)

Can't OTA update with root or custom recovery. Have to be full stock. Will have to fastboot the factory image. Might as well do latest 5.1.1 for your carrier. If going to do root and recovery will have to forget about OTAs and flash factory images.

I appreciate the reply..... that is exactly what I have come to learn.... (the hard way)
I guess I need to figure out:
1) if the 5.1.1 is much of an improvement over the 5.1 I have now
2) Find the correct 5.1.1 image for my N6
3) Learn how to fastboot it.... I seem to have issues getting the commands right....
Do you know of a step by step I can follow with all the proper commands?
You guy will have to forgive me as I am very novice in this and although I thoroughly enjoy knowing I did it, the pure terror of possibly bricking my $600 phone scares the hell out of me.

BTW batterylife is mainly determined by the setup of the phone and usage of the user, not so much by roms and kernels

More than likely your battery is being ate by something you have loaded on phone. There is a T-Mobile based rooted rom here. If want to try it can just flash in recovery but wipe everything including data in TWRP. Full wipe will make a big difference. System, dalvic, cache.and data.

Ok guys, I appreciate all the info. It helped allot. Thank you
I did manage to get CyanogenMod 12.1 nightly on it which is 5.1.1 but now I have run into another issue that I cannot figure out....
Whenever a notification calls for one of my added notification sounds to play, it doesn't play the sound and a pop up comes up and says "Server died" when it tries to play the sound.... It plays all the preinstalled sounds and all my added music, it's just notifications in the wav format that it keeps giving me the "Server died" error on and it's not all the wav's I added, just a few... It makes no sense to me... I've taken them back off, rebooted the phone, added them back on and it will not play them at all.. These are the same notification sounds I have used for years on all my previous android devices and never had this issue with them working before... Everytime I get a new device I just transfer them over....

Rooted Nexus 6 and updating to android 6.0

Hello all,
i rooted my nexus 6 and now that android 6.0 has been release i can't install the upgrade. My phone shows there is a system upgrade available. I have clicked to download the upgrade. Now its showing that a system upgrade has been downloaded and verified. Once i click on install update, it reboots to the teamwin. And to be honest, i don't really know if its taking the updated or how i can upgrade if possible.
can someone help me please?!!!!

Same answer every time. You can't get the OTA if you're rooted.
Options are :
- flash factory image (see sticky roll-up in general)
- flash a pre-rooted zip from recovery.

if you dont want to lose your data. just flash system.img, boot.img and recovery.img of your current build.
you can extract the images from the factory image...

Not only that, but by attempting to apply the OTA on a rooted device you risk bootlooping it, as I did with my Nexus 10 a couple of years ago.
Your best bet is to use Wugfresh's Nexus Root Toolkit (NRT). Since this is a major upgrade you can't use the "no wipe" option, so you'll lose any data that you haven't backed up first - photos, etc. - so do that before you do anything. Also take a TWRP backup of your current ROM and copy it to your PC so that at least you can recover to where you are now. NRT also has a backup option.
If you tell NRT that your current ROM is MRA58K (Android 6.0) and then tell it to flash stock and unroot, it will pull down all the required files before applying them to your Nexus. You can then re-root if you want to. It's a beautifully-engineered program, pretty well foolproof if you follow the instructions and choose the right ROM for your device.

It cant get to that stage any more.

Thats good news. What changed? Ever since that experience I haven't even tried an OTA. I was abroad at the time and lost the use of my Nexus 10 for most of the holiday.

OTA zips used to check individual files in system to ensure they matched before updating. It checks either md5 or sha hash. It didn't take account of every file or even files added by the users. so upgrading could cause issues.
Now, it checks the md5/hash of the entire system, which means all files are taken into account.. It will not flash of anything is changed.

Thanks - happy to roll you over to 19,400...

A new Start !!

Hello fellas,
After a long time I've decided to be back on Nexus, can't enjoy without nexus phones, ZF2 developement is stagnant as ASUS is not releasing src, a great HW stuck by OEM limtations.
So I've got my N6 today, I've learnt a few things before like not downgrading bootloader, had a post saying which versions are safe and ones that are not iirc <71.08 shouldn't be flashed onto 71.08 existing BL right or was it 71.10 ?? (idk why will anyone want to downgrade unless they want OTAs based on Fi, root is superior to all. Heard a few CM roms had BL packed into ROMs and the updte to 5.1.x + lower BL caused hardbrick, a.k.a bootloop + noTWRP with Fastboot lockedout ).
So here's my to-do list sorry to post this long but seems like this is start for me....Please correct me If I understood anthing wrong....as It's been a long time since I used a nexus (Maguro was my first nexus and things rapidly changed these days..)
1 - mFastboot for flashing
2 - OEM unlock check prior to unlock the phone (shipped with 5.1 LMY47D so I may need to do this before proceeding)
A few questions -
3 - Does NRT has mFastboot ? I have it in my computer tho.
4 - Can any one give me crash course for SuperSU + MultiROM with 5.1.1 (Need Xposed:silly, 6.x & Nexus 6 information....
a- Like If I OEM unlock my n6 now and use 5.1.1 CM based it has pre-root right ? So I shouldn't bother with SuperSU BETA 2.6x right, next is the systemless root is because of M's warning messages ? why all this hassle of
**root** as of lately with L and M, Is it because of SELinux policies + M's changes with System related messages ?
b - MultiROM working guide on 5.1.1 plus M latest release anyone, will try the official thread tho, any info on whre to start would be awesome !!
5- I should be good if I unlock the nexus and use an EX / Lean / Despair / Blu-Spark / or any kernels - these do have modified system so how about the M's warning msgs? are the custom ROMs on M are modded to avoid any nagging messages like that?
6- Please link me any useful posts/threads that are updated to reflect latest changes like SU or any old information that is essential !! thanks !!

1.) I don't think you need mFastboot. I think you just want standard fastboot with Nexus phones
2.) I'm not sure what this means, but just follow the beginner guide in the General section to unlock the device
2a.) Follow the advice in answer 2 for fastboot information as well
3.) NRT installs standard fastboot and adb into C:\Program Files(x86)\WugFresh Development\NRT\Data\ folder
4.) Can't do it, I don't use multi-rom.
5.) There are special instructions for installing custom kernels. Follow the directions mentioned within the threads
6.) This information will be available in the custom ROM or kernel threads you choose to use

Thanks,
Last time I had a nexus 6 just for a couple of days which I returned for various reasons, I had the firmware error upon flashing the imgs from 5.0.x to 5.1.1, after googling a bit I used that mFastboot, but wanna confirm it..

I'm pretty sure mFastboot is made directly for a Verizon variant, but since the Nexus 6 is unlocked and your Verizon SIM card dictates the network you are on, I would say stick with normal Fastboot for your flashing endeavors. Good luck and read twice, flash once :good:
Edit: Quick side note, love the avatar. Good choice.

Thankyou :highfive:
Just did an OEM unlock and wierdly after that, the bugdroid loading doesn't end at all. Did an factory img flash of 5.1.1 Shamu-LMY48Y and booted in less than a min Lol.
And yes the fastboot is working, wow things are definitely wierd with Shamu (volume normalization, mFastboot previous xperience, bootloader bricks...seems like Qcom fixed that after CM brickbug and no one can help the manual bricking) but I'm ok with all these , just love this device, massive, powerful and sexy looking piece
EDIT :
Well everything's going fine but this bugdroid loading doesn't seem to be fixed at all, after bootup 23Gb was there so I did a format and again stuck, this time around I tried using TWRP to flash (CM12.1)after doing fastboot commands - fastboot format userdata, cache. Now it says unable to flash on so&so data partition, So formatted from the OS and now MTP says generical heirarchial. I don't remember any device with that format...
EDIT 2 : Device won't boot with that bugdroid formatting the Data partition. Needs to be fastboot flashed else stuck there forever again same 23Gb bootissue if I do that & Using fastboot format userdata command it formats into the 64GB - 54Gb available space but with TWRP It fails to flash - the same error, can't flash on data parition. So repeat fastboot and it's a damn cycle. Will try to flash MM if it won't then. I may have to return again...OMG
EDIT 3 : http://forums.androidcentral.com/go...ys-formatting-data-yellow-text-any-ideas.html
http://forum.xda-developers.com/google-nexus-5/help/help-stuck-formatting-data-t2737793

EDIT : Tried MM and after 10 mins formatted succesfully now gotta try a ROM or any, hope its fine !!

Again the GH FS is back with MTP and doesn't flash at all with TWRP. If I go for a re-lock and it it fails to boot with formatting properly...then bam nothing but a bricked Nexus !!
TWRP did the format but the device is messed up, sliptscreen issue..
I'm going to return this, enough of the hassle had me messed up totally :crying:
Seems like 6P seems better than having all these issues. Or wait for the 2016 device...
EDIT : Sorry for the GH format seems like it's normal, but the flashing issue is too wierd..

I dont know what the **** a bugdroid is.... But just use fastboot to flash things. Post up console messages and we can help.
If you flash userdata.img, its for the 32 gig model... But you can use TWRP to expand the partition to give your space back.

I know this issue, just a factory reset fixed this thing on my old N6 that I had for 2 days, but this takes too much of time to format....Just had TWRP do the job and flashed the Temasek but ALAS !! Splitscreen issue.

May 2020 QQ2A.200501.001.B2 "FLAME" Magisk-Patched Boot Img [+UPDATE/KEEP ROOT GUIDE]
Another month, another update. I'll keep churning out these patched / stock file uploads and easy noob-friendly update guides while guinea pigging the updates, so long as my area is still on lockdown and I'm not back to work yet, lol.
I've also installed and tested / verified that Kirisakura 4.2.0 is working great with this month's patch so far.
Also have EdXposed Canary 0.5.0.0 (4548) YAHFA installed. SafetyNet still passing as of now.
Magisk v20.4 Patched Boot Image: https://www.androidfilehost.com/?fid=4349826312261796525
Factory Untouched Boot Image: https://www.androidfilehost.com/?fid=4349826312261796524
THESE FILES ARE FOR 10.0.0 (QQ2A.200501.001.B2, May 2020, All carriers except TW) ONLY! PLEASE ONLY FLASH IF YOU KNOW WHAT YOU'RE DOING!
If these files and/or guides are helpful, please drop a thanks and let me know. =)

EASY UPDATE / SEAMLESS KEEP-ROOT UPDATE PROCESS (using a PC - a very intuitive, effective, and relatively safe method).
** You can only follow this guide exactly if coming from build QQ2A.200405.005, Apr 2020. But the general idea is the same for other builds, you just need the correct files for your device.

May 2020 sideload OTA zip: https://dl.google.com/dl/android/aosp/flame-ota-qq2a.200501.001.b2-46940f66.zip
I DID NOT BOOT BACK INTO O/S UNTIL ALL STEPS WERE COMPLETED - I DID THIS TO ENSURE EVERYTHING WOULD BOOT BACK UP WITH MAGISK / EDXPOSED ALL RUNNING PROPERLY RIGHT AWAY
1. boot into bootloader
----------------
** I was on custom kernel, so I needed to flash BOTH the stock boot and dtbo images
2. fastboot flash boot flame-qq2a.200405.005-factory-boot.img
3. fastboot flash dtbo flame-qq2a.200405.005-factory-dtbo.img
......* these steps to restore stock recovery; dtbo.img also necessary for some kernel installations
-----------------
4. use volume keys to change selection to boot to Recovery Mode
......- when you reach the android symbol with No Command, hold power button, tap volume up, in case you've forgotten
5. choose option "Apply update from ADB"
6. adb sideload flame-ota-qq2a.200501.001.b2-46940f66.zip
7. Once the OTA sideload is done, Reboot to bootloader (you'll also notice it's now on the other slot after OTA flashed)
8. fastboot flash boot flame-qq2a.200501.001.b2-magisk_patched-20.4.img
9. done, start the phone
(Optional - Flash custom kernel. If you had a custom kernel, you need to re-flash it. I've only personally tested with Kirisakura though.)
This was a 100% seamless update that required no additional / re-setup of any of my Magisk or EdXposed setups. All of the factory files can be found here https://developers.google.com/android/images. boot.img and dtbo.img are in their corresponding full Factory Image zips, and the ota zip is under Full OTA Images.

Thank you for making this so convenient!

You can thank my wife for going with the P4 instead of P4XL . Now gives me 2 phones to keep up with, although they're basically identical in process. Might as well share with yall over on this board, which seems to get a little less love and attention. But we're definitely lovin the switch to Pixels. Awesome camera too, which is great because we just had our first child 4 months ago and these phones take amazing photos. And this is coming from 2 phones that already had great cameras (HTC U11 and U12+)! I love taking photos when he's sleeping using Night Sight mode. He's so adorable, it comes out so clean, and there's just something about that sleepy ambience .

i just saw on my google news feed that the May patch just started dropping to our devices. i go check XDA and this post is already here. wow that was fast haha! went perfectly smoothly just like last month, thanks so much!!

Why not update the OTA via Magisk, or is this only for those which devices is not able to download OTA:s?
Currently, I have rooted with Magisk, still waiting for OTA update notification in my device...

Should i restore images in Magisk and/or disable any modules or just let 'er rip?!

@Vantskruv: FYI, you won't get the OTA update notification because you're modified right now. You can restore the boot image in Magisk first and wait for the OTA notification (what you're thinking of is something like this: https://forum.xda-developers.com/pixel-4-xl/how-to/guide-update-retain-root-t4003839). But from what I understand, it's pretty hit or miss. Apparently it's hit or miss even on complete bone stock anyway lol. The method I outlined just works nice and reliably even when rooted and modded.
@redeyss: Restoring the stock boot image in Magisk Manager is similar to the method linked above, and then taking the OTA the normal way. But if you flashed a custom kernel, keep it mind it won't restore the dtbo partition (not sure if it's necessary with that method tbh). You shouldn't need to restore images in Magisk, nor diable any modules. When you flash the factory April boot and dtbo images, it's doing the same thing as restoring the images through Magisk (plus dtbo). Just let er rip, and if you have any issues, you can always flash the new unmodified factory boot image, which will essentially disable Magisk, and then work from there. It's a very safe method. =)
edit: also in the event of bootloop, this is a great thread to read and understand: https://forum.xda-developers.com/pixel-4/how-to/magisk-modules-disabler-booting-magisk-t3991739

Thank you @i5lee8bit for your answer. Luckily I have restrained myself yesterday to update, thought I where in the Pixel 4XL thread, while this is for the Pixel 4. :laugh:
I am just curious, do any of you expert guys/girls know why this is happening, that OTA updates is not pushed on rooted phones?
Do Google have algorithms that temporarily bans systems which is rooted?
Or is it so simple that some type of fingerprint is changed when rooted, so Google update services does not recognise the device, and not pushing OTA:s?
Sorry for the questions, no need to answer them. It was a long time ago I rooted Android:s, and I have forgot many things.
I think I will try to manually update everything, even though there are more steps included, just to learn how to do it.

No worries, the process for the 4XL is the exact same, but good catch; you definitely need to use the correct files for the device. I actually posted a similar thread with the relevant 4XL files over on that forum.
Not sure exactly the mechanism used to prevent the normal OTA, but probably just checks for a modified boot partition. In any case, the normal factory OTA if I understand correctly relies in part on factory recovery commands at some point, and a modified boot partition won't be able to use them. In fact, try booting to recovery with the modified boot partition flashed and you'll notice it can't load recovery. I may be wrong about the exact reason though. But think about it: even if we had TWRP, the factory OTA mechanism can't make use of it. Even if the OTA popped up while rooted, it probably wouldn't be able to do it, or worse, cause a failure and corruption. I would dare say we're fortunate they prevent factory OTA when running modified.
Anyway, there are a lot of complicated guides out there, and that's why I wanted to share my method. I didn't need to do any further research and it's very intuitively sound. Steps 2+3 essentially restore stock boot and therefore recovery (and dtbo), the rest pretty much follows a standard OTA sideload, and then it's structured in such a way that you're flashing the new Magisk patched boot image before even starting the phone back up. Making it a seamless, keep-root easy upgrade.

Wow ..... what an easy, elegant way to get my Coral device updated while keeping root. Followed the OP process, but used these commands instead to get the June 2020 security update:
- fastboot flash boot coral-qq3a.200605.001-factory-boot.img
- fastboot flash dtbo coral-qq3a.200605.001-factory-dtbo.img
- adb sideload coral-ota-qq3a.200605.001-3b5bb1bd.zip
- fastboot flash boot coral-qq3a.200605.001-magisk_patched-20.4.img
Thanks, @i5lee8bit . Well done. :good:

does anyone have a thread to point me to that is a step by step guide for setting up ADB and how to flash? I did everything a year ago but now I just factory reset and am stuck in boot loop, can't remember all the commands and everything.
