Can/Should I install update? - Google Pixel Questions & Answers

I have my Pixel (obtained from Google) rooted. I have not installed any Kernels or Roms.
I received a notification that there is an Android system update. Is is OK to install this update?

Based on your comments, I assume you are not on Verizon - if that is the case, whether you do an update or not is completely up to you - I have the GOOGLE PIXEL - am using ATT service and I am also rooted - I updated - ultimately I had to re-root - install Twrp and flash the rom I wanted to use - but beyond that - no reason not to - completely up to you. Good luck.

So, if I install the update, I will lose TWRP and root?

You never want to take an OTA update if you have a custom recovery. Can and will brick your phone. As long as you have stock recovery your more than welcome to take an OTA update.

Restored factory boot.img to boot_a and boot_b
When I try to install the update, it says "Installation Problem"

how to update Android via OTA when Multirom and TWRP are installed

Hi,
today I received a security update in my Nexus 5. I accepted it and when rebooted it got stuck in the multirom menu and it didnt update anything. Last time I have to lock the device and flash the rooted image in order to proceed with the update. this time I would like to do it diferently if possible.
Is there any other way to flash the update without removing multirom and locking back the device?
where is the update.zip stored when the system automatically downloads the update? maybe I could manually flash it using the TWRP.
thanks!
Jose

Stagefright update (LMY48B->LMY48I)

I bought a Nexus 5 (refurbished) from Freedom Pop. I can't remember what version is came with, maybe 4.4.4. First thing I did with it was install CWM (6.0.4.7) and flash the Google Nexus 5 factory image (5.1.1 / LMY48B) and root the device. Now that LMY48I is out, I got a OTA notification about a system update. When I try to do the OTA update, it fails. So I downloaded the update zip to take LMY48B->LMY48I from http://www.droid-life.com/2015/08/10/download-nexus-4-5-6-7-9-10-ota-stagefright-patches/ . I boot into CWM and install zip, but it fails with:
Package expects build fingerprint of google/hammerhead/hammerhead:5.1.1/LMY48B/1863243:user/release-keys; this device has google/hammerhead/hammerhead:4.4.2/KOT49H/937116 Instllation aborted.
When I go to Settings, System, it shows I have LMY48B. Why does the install think I have KOT49H? When I flashed the factory image it did it not update some file somewhere and if so, how can I get that file to accurately report what I'm running?
Thanks,

You must return to stock before you attempt to install that zip. That means you cannot be rooted or have custom recovery in place
I've got a stock N5 I bought from Google on LMY48B and there's still no update for me.
Does anyone know what the roll-out timeline is for the LMY48I?
When should I conclude that I'm not going to get it OTA and resign myself to factory wipe and flashing the image?
I have a stock Nexus 5, rooted w/ cf-auto-root, re-locked , no custom recovery or bootloaders, and all i see is Error when trying to install this OTA. I'm stuck at the moment myself. Installing the OTA should just unroot my phone, but it won't install. Currently running on 5.1.1 (LMY48B) myself.

I have the same problem her as well with my nexus 5 it keeps saying error with little droid I've tried side loading manually but it didn't work also tried hard reset and wiping cache but nothing solved the problem so i just figured out the problem is the package it self
Same problem here
Same thing here, error with little droid picture on rooted android 5.1.1.
Has anyone found the reason for this ?
Try flashing system image directly

This possibility makes me spend a lot of time, becouse i have lcd_density changed and all apps when i restore a backup are not in the main screen.

This method is for anyone with lmy48b that's rooted or has a radio, kernel or recovery custom flashed.
Condensed version but here's the important pieces. You will lose root if you are unrooted. You will not lose any data or settings if done this way.
Step 1. Download lmy48b from google
Step 2. Unzip lmy48b package
Step 3. Copy bootloader, radio and system.img from lmy48b package (unzip zipped file for bootloader and system.img)
Step 4. Connect phone and boot into bootloader
Step 5. Type in fastboot flash recovery [recovery].img replace [recovery] with the actual file name
Step 6. Type in fastboot flash radio [radio].img
Step 7. Type in fastboot flash system [system].img
Step 8. Reboot
Step 9. Update via OTA
Working - confirmed

Thanks, confirmed that this method worked. Managed to update my rooted nexus 5 to LMY48I
Tried to install ota update after reverting to stock recovery using Simple Recovery Switcher app. However, also the error message, with little Android picture also appears. Please help
I assume this removed your root, though.
It seems we are getting a new factory image en september to properly solve the stagefright bug
"A second patch has been sent out. "We’ve already sent the fix to our partners to protect users, and Nexus 4/5/6/7/9/10 and Nexus Player will get the OTA update in the September monthly security update"
I have decided i will stay at 5.1.1 untill Android M maybe september also. In the meanwhile i have disabled MmsService and OTA.

I'm with you, not going to try to flash these things, there are a few zip files out there dated a couple days ago, apparently the zips aren't tested prior to release since everyone is getting failure when flashing the zip file.
Is there really no method to apply OTA updates on rooted/modified devices (e.g. modify the update.zip itself to bypass whatever checks it performs)?
Same problem here- only had a custom recovery and root. brought back the stock recovery and did full unroot from SuperSu.
OTA update installtion stops with "Error".
Just flash the system image from the update.

Thanks, I ended up doing this http://forum.xda-developers.com/showpost.php?p=62288667&postcount=196
(flashing stock system, boot and recovery from my current version, letting OTA update install and re-rooting according to http://forum.xda-developers.com/goo...ide-nexus-5-how-to-unlock-bootloader-t2507905)
I guess i could have flashed the new version just the same.

Using FlashFire to apply OTA upgrades?

I have a rooted One Plus 6 running on stock Oxygen OS 9.0 There is an OTA update available at the moment. I have used FlashFire on my previous phone (Nexus 6P) and it worked flawlessly in keeping the root and applying OTA updates without any steps required. All I had to do was launch the app, it detected the firmware, and I would let it install. I purchased the professional version of the app as the free version stopped working at some point.
When I launch the same app on my OP6 and select "Flash zip or OTA" option I get another screen that has three options to check:
1. Auto-mount: Mount common paths before running update. Rarely necessary. Enable for A/B device OTAs, disable for all other OTAs.
2. Mount / system read / write: Mount /system read / write by default, rather than read-only. Doing this only once may break the future OTAs, Enable when flashing custom firmwares.
3. Restore boot and recovery images: Attempt to restore boot and recovery images before flashing. May be required for some OTA. Disable for non-OTA updates.
What's confusing me is the third option as that is already checked. It sounds like this option would install a factory image back on the phone? Should I uncheck it and check #1 as the only option?
If your bl is unlocked then you can't use ota to update. You have to flash the full zip in twrp.

I just found the instructions for update in another thread. I will have to use the blu-spark twrp to update it. Since I have never done it before, my question is, is it going to leave all the data and the app data intact? Things like pictures, videos, messages from messaging apps? Because in my mind I always thought of flashing the full image the same way as reinstalling the OS on any desktop computer - it deletes everything.
I am guessing the answer is no?
Is your bl already unlocked?

okay so if you have it setup Google will backup your apps calls and network settings and you will be able to sign out to your Google account and choose to restore it. For photos.. If you have Google photos installed it will backup everything you have told it to. But you shouldn't have to worry about any of this if you are just dirty flashing the update. Everything will be the way it was is like an ota only difference is you manually flashing the full room zip in twrp. So if your just dirty flashing you shouldn't lose any data.
Thanks! I will give it a try sometime later this week.

Custom ROM

Hello, will it be possible to return from custom firmware to the original one and continue to receive OTA update ?

Yes, if you used TWRP to create a backup of your stock ROM before you flashed a custom ROM, you just use TWRP to restore the backup of stock ROM.
Or, if you didn't use TWRP to backup your stock ROM, you can flash your device's stock firmware using the flashtool designed to be used with devices made by your device's manufacturer.
But to install TWRP you need Root, and if you get it, then OTA updates stop coming or am I wrong?

No, installing TWRP does not require root. Yes, TWRP and root prevent the installation of OTA updates.
That is, to make a backup copy of the original firmware, you need TWRP, but if you install it, you lose the ability to receive OTA updates, and if you restore the original after the custom firmware, there will be no updates? Or can TWRP be removed and OTA updates will come again? I'm sorry I do not understand.

To be more specific, installing TWRP does not necessarily prevent a device from actually receiving/downloading OTA updates, it prevents the actual installation of OTA updates because part of the OTA update includes automatically booting into stock recovery to apply the update. If you have TWRP installed, the OTA update can possibly be downloaded to the device but when the device automatically tries to reboot into recovery, it is trying to boot into stock recovery but if you have TWRP installed, it can't boot into stock recovery to apply the update and when it tries to boot into TWRP, it will try to apply the update but it will fail, resulting in a bricked device and the device will have to be restored.
When it comes to OTA updates, all that is required is an unmodified stock system partition(meaning, no root or any other kind of modifications to the system partition), stock recovery(meaning, no TWRP) and the update has to be offered by your carrier if they offer the update for your specific device.
If a device is rooted, has other system modifications and/or has TWRP installed and you want to apply a stock OTA update, you have to remove root and any other system modifications and you must replace TWRP with the original stock recovery before you can apply the update. If you have TWRP and or root and you remove them to apply an OTA update, you can root the device again and install TWRP again after the update, provided that the OTA does not come with a locked bootloader that can not be unlocked, in this case, you will not be able to reinstall TWRP or root because the bootloader will be locked, which prevents you from installing TWRP again. Sometimes, users remove root and TWRP to apply OTA updates with the intention of rooting and/or installing TWRP again after the update but then get stuck in a position where they can no longer root the device or install TWRP because the bootloader gets locked during the update and there is no way to unlock the newly updated bootloader, from then on, they are stuck with stock with no way to get root, TWRP and custom ROMs reapplied to the device because they were not aware that the update came with a locked bootloader that can not be unlocked by any means.

Question Tmo users who converted to global at A11-OOS11, how did you get to 13 rooted?

I cant do normal OTA updates, nor can I install them with the built in installer in settings (that I gained with conversion). Im not exactly sure why and trying to figure this out. Were you able to update as normal to A13?
Its possible I broke something (cant think of what), so Im restoring my after-root twrp "base" backup to see if it can OTA.
Figured Id ask in the meantime...

You have to uninstall magisk/restore images. Then start ota. Then before you reboot go into magisk again and install to opposite slot and reboot . After ota has installed. Stock boot image is the only way it works. It's will fail upon checksum of partitions by google
I figured as I just went back to my base savior A11 rom fresh root, and still nothing. Thank you!
Uninstall magisk it automatically restores boot images right?
*Actually do I need stock boot? I have twrp. Where do I get stock boot image?
Im screwed. Its unable to restore my old image from usb, so Im bricked now. No idea what to do.

Do you know how I can get back to stock boot?
NM found it. So to be sure, when i want to move from A11 I need to uninstall Magisk, boot to fastboot, then fastboot flash stock boot.img?
Here
^But I have twrp, so wont restoring just bring me to unlocked bootloader unrooted with twrp? (*still not stock?)
*Sorry for the questions. It just seems TWRP has problems restoring backup completely (or I missed something, I backed up everything in TWRP maybe I dont need to do that?).
Im trying to avoid what happened a couple nights ago, because I lost confidence in TWRP on this phone. Usually, its just something ****s up? Well restore your backup, because you just made one. That didn't work completely (it didn't restore /data), and I had to set up a ton I dont want to do again, unless Im on custom A13 rom. Got savegames!
Thanks for all help.
I was on android 12 with april 2022 security update, so it was a very very early android 12 build. I couldn't update via OTA cause I kept getting "update failed" I was rooted, had data I didn't wanna lose so I just ignored it.
I'm now on A13 with root. what I did was: MSM tool back to A11, update via OTA until I reach final official build, extract the boot file through msmtool, patched it with magisk, flashed it via fastboot, job done.
Couldnt Magisk patch boot image from app? Instead of extracting it? Thats how I did it on 11.
I also dont know how to use msm tool to get to 11, or even where to get files. *I think this is it? General - OnePlus 9 11.2.22.2 (T-Mobile) MSM Download Tool | XDA Forums
*Thats exactly whats happening to me too. update failed. So I guess this would be a sure fix.

Wait. How did you unlock bootloader (after MSM put your phone back to lock BL I assume)? Is the option later available on Tmobile roms? Did you need a token?

you get update failed bec. of the magisk image. you have to restore to stock image before you download the OTA. in magisk dashboard, go to uninstall magisk. choose RESTORE IMAGES. download the ota. do not reboot. go to magisk and install magisk. choose install Magisk after OTA (or something) then press Let's go. and reboot.

Doesn't having twrp boot image installed mean that magisk restored twrp image to when before magisk patches it (so it's not actually stock)? Doesn't it just restore a non rooted image with twrp on it?
