I've downloaded the ota zip and ready to flash it in twrp. But when I flash it, it shows an error saying my device have wrong build number. I'm very sure that i have kitkat ktu84p but when flashing the ota it says i have the previous jelly bean build which makes my flash unsuccessful. I've also checked build.prop and its also listed there its ktu84p. Whats the problem here and if possible show a solution please

Thanks for the link. Now i can conclude that the ota doesnt work with custom recoveries. Tried twrp and cwm. Twrp shows jelly bean fingerprints but cwm shows another kitkat fingerprint rather than ktu84p thats suppose to be

Wonder if you are using an outdated TWRP version. Maybe the newer versions have fixed this

Hello!
Really want to flash the OTA without a total wipe.
First flashed it from TWRP 2.8.1.0 and got the wrong build finger print says I have Flo:4.3/JSS15Q/779366 and it expects KTU84P/1227136
Then using WugFresh 1.9.4 flashed stock recovery so I could sideload then encountered the whole adb disappearing in recovery - eventually solved that and finally managed to adb sideload saw my screen saying it was installing the update using the stock recovery - YAY! It was short lived as the stock recovery screen told me the exact same thing that TWRP had told me.
I looked at my build.prop and it says my ro.build.fingerprint=google/razor/flo:4.4.4/KTU84P/1227136. user/release-keys
Can someone enlighten me? I've wasted so much time on this I would love some keen insight - PLEASE!!
Thanks for any and all help!

Google changed the way OTAs work in 5.0. You will usually not be able to flash a OTA if your OS is modified. Means no custom recovery or root. You will have to flash your tab back to stock kitkat.
Before it would patch individual file blocks, now it patches the whole system partition as a blob. Read more http://www.androidpolice.com/2014/1...e-means-update-will-fail-system-modified-way/
Workaround that helped me upgrade
Following the steps below seems to have done the trick for me. My issue was that Android 5.0 updates the system partition all in one go now, rather than each file separately. Following those steps will unroot your device but will allow you to install the OTA updates.
So follow these steps to refresh your current Android version (e.g 4.4.4) then use OTA or adb sideload to update to, for example, 5.0.
This will not wipe user data or the cache.
Download the Factory Image for your current version of android from google (4.4.4 most likely)
Extract each level of compressed files until you get to a .zip file (inside will be boot.img, recovery.img, and system.img)
Move these files to your ADB directory (optional step, makes the commands shorter)
make sure your device is connected with working drivers and is in bootloader mode ( adb reboot bootloader )
perform the following commands:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system
fastboot flash system system.img
Finally, (Re)start the system
After this if you want to root and reinstall a custom recovery , follow the normal steps.
I would post my source, but as I only just joined to say what helped me, I'm not allowed to post links I'll just say Google "flashing-a-stock-android-image-without-wiping-user-data" and (as of 19/11/2014) it's the top result.
Please continue here: http://forum.xda-developers.com/nexus-4/help/android-5-0-0-to-5-0-1-update-t2972371#post57515317
Finally finally!!! A fix!

Thank you Raingram! This worked perfectly!
I have made a lot of changes to the November build such as TWRP, root with magisk, custom kernel and Tulsa mods to the systemUI and framework.
I am thinking that I will need to reset to factory default in order to get the December update. I have not done a factory reset yet.
Sounds like I use Flashall.bat with the - w option removed and the phone in Fastboot mode.
Do Magisk or TWRP need to be removed before Flashall?
Will there be a full December build or do I flash an old build and then take the updates?
Any other suggestions on the best way to update to the Dec build?

There Dec flash-all batch file, without the -w, will over write all your modifications and that's all you should need to do. It's always best to backup everything you can just in case.

So can you not download the ota from Google's website and flash it in TWRP? Then just flash TWRP and root again before rebooting?

Not in TWRP, but you can ADB sideload it then reroot. The flash all after removing the-w also saves data and apps.

If you don't install the permanent TWRP, and just use the bootable image, you can place the OTA on your phone and use the stock recovery to install it. The OTA will install without wiping data.

Right, but then you need to reroot with a PC. I have TWRP permanent so I was hoping you could just boot into TWRP and flash it, then flash TWRP again and then root and be back to the way it is now.
So in my case I need to just download the images, remove -w and then flash. Temp boot TWRP and flash root. Don't think I'll put TWRP on permanently this time since that was the only reason I did the last time.
Thank you everyone for your help
Hi all, I have TWRP + Magisk on my device and I am attempting to update from PQ1A.181205.006 to PQ2A.190205.001.
Steps taken
1. Downloaded the OTA from here: https://developers.google.com/android/ota#crosshatch
2. Moved the OTA to phone storage.
3. Checked SHA256 checksum matches.
4.
Code:
adb reboot recovery
5.
Code:
fastboot boot twrp-3.2.3-3-crosshatch.img
6. From TWRP > Install > OTA zip file
Fails with the attached error. I have also tried sideloading through TWRP with the same result. Has anyone hit this error or successfully flashed the OTA update through TWRP?
I have not heard of anyone successfully loading an OTA through TWRP. Either restore stock recovery (install boot.img to both slots) and sideload with the Google instructions or run the flash-all (remove the -w) to use the factory image. Either way, you ere going to be reverting to stock recovery.
P.S. Your message doesn't make sense since you say you have TWRP on your device but then are showing that you used fastboot boot to run the TWRP .img file. If TWRP was on your device, you wouldn't have to use that command. You would just have entered TWRP with the adb reboot recovery command. I am guessing you are rebooting into the bootloader screen where either you run the TWRP .img or run the flash-all.
I also thought I saw a previous post somewhere that said you cannot skip an update, so going from December to February may not work.....not sure...
But definitely you need to load the OTA via regular Recovery using adb not TWRP....
Can you install a OTA?
I thought you had to perform an ADB sideload of an OTA.
Even then I am not aware that ADB sideload works for Pixel 3xl yet.
I have been flashing the factory image with -w removed.

ADB sideload works fine for the OTAs in stock recovery. That's how I've been doing mine.
On a side note, the Essential phone is the only phone I've come across so far that TWRP will flash the factory OTAs.

Flash them or sideload them? I never had a P2XL, but I had a Nexus 6p and I don't remember being able to flash that with the factory zips. That doesn't mean my memory isn't shot either.

Tap install on the twrp home screen. Then go to where you have the boot.img on your internal storage and tap image on the bottom right. Then select the "boot" partition, and swipe to install. This will return you back to stock recovery and kernel :good:

Well I managed to do that, but now when my phone rebooted the touch screen no longer responds. Very strange. It all loads fine and I can see my screen but nothing works. I tried to go back into recovery and I get the little dead Android guy laying on his back with a red exclamation point and "No Command" below it.
Any ideas?
I really don't have a clue how to get auto updates via System Updates on my rooted Pixel 2 XL (Pie, Magisk 18.1).
If I check updates it replies that I already have the latest version (still from February 2019).
Is it possible to get updates via system menu on a rooted phone?
P. S. Sorry if I've missed a right thread for this topic)

No, you will have to manually update on a rooted phone. It requires a computer but only takes a couple minutes.

It will not wipe your phone as long as you remove the -w. Magisk and Twrp will have to be reinstalled but that's an easy process. Fastboot boot the twrp.img file. That will get you back in to twrp temporary so you can flash the twrp and magisk zip files.

Mostly personal preference.. if you use the side load method you need to download the ota file instead of the full image. I personally prefer flashing the whole image in fastboot. In my experience there is less room for user error but that's my opinion.

This!!
Phone is rooted with magisk, running Feb '20 build.
Last month (early Feb) for a split second, I saw the message 'preparing system update' when going to settings - system - system update. Then it went to 'system up to date' (back then it was obviously running Jan '20 update). So I had to download the factory image, patch the boot image and flash it in fastboot to be updated and rooted.
Saw the March update was available, went to system update again, no and behold. Same story. Split second 'preparing system update' and then nothing.
Oddly enough device updated to the januari update through magisk ota procedure just fine.
Has anyone else encountered this? How did you fix it?
Sent from my Pixel 3 XL using Tapatalk
I encountered this last month. Did the Magisk OTA update like you for January and wanted to do the Feb OTA update but it never became available on my phone. Just checked System Update and it says system is up to date. Haven't seen the "preparing system update" for March - yet.
Same here. Magisk OTA method in January then the preparing message then up to date last month and this month.
Seems Google is on to us.
When I get home I am going to unroot via Magisk, not reboot and check again.

Use This guide: Do #4 'keep data' then #9 to root.
It only takes 5 minutes.
Note: Before you start disable all your Magisk modules.
So long story short: download factory image and remove -w (wipe flag), flash everything, patch boot image with magisk, and flash image via fastboot. Now what I don't see (or I overlook it), do you flash the patched image via
Flash boot patched_boot.img or to both boot_a and boot_b?

Yeah it's not showing any OTA updates since ~January. I think there's some corrupt folder/file permissions after one of the OTAs or something - I can't use a log viewer app to check the logs. Tried to just flash stock Feb thru fastboot like you suggested and afterwards, even with the stock boot, I couldn't find any updates. I'll try to do a factory reset when I have time to see if that solves the issue
EDIT: Got it working after I used https://pixelrepair.withgoogle.com/ to reflash. When I tried factory resetting by follow @Homeboy76 's guide (w/o using the laptop), it still wouldn't find an OTA. The site got me back onto Feb stock and I rerooted and applied the OTA afterwards

Maybe a factory image with -w would work? I'm not sure what exactly the pixelrepair site does but it seemed like it was doing a sideload after wiping data since it asks you to go into recovery mode
Don't care what the pixelrepair does, as I said. I can't use it. Probably Geo restriction.
