[Q] Error while installing 5.0.1 update

Hi I just got the 5.0.1 update, I downloaded it and the phone rebooted itself, I got the installation screen and after 5 seconds I just got the word "error" and I had to restart it manually; the device is rooted, have anyone else had this problem? I would appreciate your help

With lollipop you can't take an OTA if you are rooted or running just about anything else modified (custom kernels, like ones that have force decrypt disabled also will cause it to error out).
You can still flash it manually by flashing the images. If you don't want to wipe, don't flash the userdata.img . Also, if you aren't currently encrypted, booting up with the stock kernel will force encrypt your device, so don't flash that if you want to stay that way. You can then re-root. There are more in depth instructions for doing this out there if you search around for them.

My Nexus 6 took 5.0.1 just fine, but my Nexus 7 does this same thing, running stock ROM/Bootloader/Recovery/etc. The ONLY thing done to it is the Fastboot OEM unlock, but I doubt that alone would stop it. I'm curious to know what resolves this ( other than downloading the factory image and flashing it without wiping the userdata )

Just got same error. I didnt even root phone, bought it today, it installed apps from backup of my previous Nexus 4 and OTA is failing.

So basically the only way is to flash the image manually? If I choose not to flash userdata.img my phone data (photos, contacts, apps, etc) won't be erased right? But I will lose root correct? Thanks!

Correct, with Lollipop if you modify things you basically are then forced to manually take the updates. Not that big of a deal as you would likely be needing a PC to reinstall your custom recovery or re-root anyhow after the update.
Flashing userdata.img isn't necessary to update. Neither is recovery.img if you want to keep a custom recovery.
Also as I mentioned before, if you have disabled encryption on your device, if you flash the stock kernel (boot.img) and boot up with it you will re-enable forced encryption. You will need to flash a kernel with force encryption disabled if you want to keep running without encryption. If you haven't disabled encryption, or don't care if your device re-encrypts (this doesn't erase anything, just may take a few minutes on first boot) then this doesn't matter.

Can I manually update without removing root first? Am I going to receive an error if I don't remove it? based on what you said, I will remove userdata.img and recovery.img and that will not wipe my data right? Do I have to decompress those files or the flash-all.bat will take care of that? Thanks!

I'm interested as well. Mine is rooted and I have encryption disabled, and I have TWRP on my phone. I tried to sideload the OTA update, but I can't get my phone to start sideload. I even flashed the stock recovery to get it to go, and no dice. What do I do next?

Anyone? I would appreciate the feedback, thanks!

sideload refers to adb as I understand it. thats NOT how you flash....you use fastboot to flash so you can do it all by hand or use one of the toolkits that script it for you.

Thanks, I get that, however I wanted to know if I need to remove the root before installing the update and if I need to decompress the .zip with the .img files or the batch will do that? thanks!

If your doing from the PC you need to extract the zip file from within the image and then fastboot them. As for root, when you do it from fastboot I dont believe it matters as you will lose root anyway and need to re-root via flashing SuperSU.zip

Worked great! Thanks! Android 5.0.1 and root, no data deleted

Is it normal to not have received an update beyond 5.0? I have had a Nexus 6 since day one, no rooting of any kind and I have not received 5.0.1.
I have done the sideload method, but I really don't want to bother with it. I do however want some of these terrible bugs I am experiencing squashed. This phone is giving me lots of issues lately.
Thanks!

Can you receive and install OTA updates with an unlocked bootloader? Everything else is stock, no disabled encryption or anything just unlocked bootloader.

If you're planning to stay rooted (meaning no OTA in future) system.img, boot.img and radio.img in any order.

If you use fastboot, just run these commands in terminal (I used windows, so in order to flash using fastboot, put the image that you downloaded for the update in the same folder where you have fastboot and open a terminal there) you can rename the .img files to whatever you like and replace those name in the commands below:
fastboot flash bootloader <bootloader file name here>.img
fastboot flash radio <radio file name here>.img
Then reboot it:
fastboot reboot-bootloader
Then flash these:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
And that's it. These commands are run while the phone is connected to the PC, you have to turn it on by pressing volume up + volume down + power.
Good luck.

Updating to 5.1 without losing root nor system settings

Is there a way to sideload the 5.1 update (downloaded from the google images page) without losing the CF root AND not losing any of my system settings and configurations?
Thanks in advance.

Maybe what your lookin for. If rooting is lost simply redo the cf root process and flash your custom recovery via fastboot. Most importantly this route will prevent data loss. I am going this route but will still backup because its safer and more responsible.

Without a modified img, and using the google provided stuff, you can't keep root. Just re-root, it's not hard.

Thanks guys. Few questions:
1. Do I need to unroot before sideloading the update?
2. Would I loose my currently installed and configured apps?
3. If I'm not losing my installed apps, what would happen to my root-required apps? For example I HAVE LMT pie control installed and configured. Would reinstalling root make it work as before without the need to reinstall and reconfigure LMT?
4. I'm still using stock recovery, would that affect what I'm trying to do in any way?
5. What is the minimal set of the update's images can I use to get this update? Like I think I should probably skip the user.img if I don't want my user settings to be wiped out, correct? What other images should I skip in order to not wipe out apps, apps settings, and system settings.
Thank you very much

If doing the fastboot way like I linked (I have not read through the procedure for sideload, so I don't know)
1) no
2) no if you only flash some of the IMG files. For your purpose it seems (I'm also assuming you don't have custom kernel) these are the ones to not lose data. Make sure you follow the links in how to flash this correctly with the appropriate order and spots where to fastboot reboot.
Bootloader image
Radio image
Boot image (kernel)
Cache image
System image
Recovery image
Then reroot with the cf zip like before then reinstall the su app.
4) no we flash the new stock recovery too
5) minimal, to not overwrite the user data, above. Yup we skip the user data image

You'll have to install su since it was deleted by system.img but that's all. Note that last time I looked CF-Auto still said it was 5.0.1 but ...

Everything except user.img. You can read or run flash-base to get the Google suggested initial ordering.

Yes, I rebooted the boot loader (and it indeed showed the new boot loader version after the reboot)
After the fail message of the radio flash command, I rebooted to the system, it works, and from the baseband number in settings/about, it seems that the new radio has been flashed (besides the fail message)

hmm yeah i really dont know why that happend. I guess as long as the new radio shows up as you say then it worked. I will actually be doing this shortly, since i am now at a computer

Just updated to 5.1
for those who will read later and more importantly in my same position.
I was on 5.0.1 BL unlocked, custom recovery+root, custom kernel- -wanting to go to->>5.1, root+custom recovery (cause flashing kernels is trivial) without any data loss (basically don't flash the userdata image) (also you could have left out the radio, I guess if you don't want newest radio, and the boot if you want to just keep your kernel--**not 100% about these two though)
I flashed via fastboot the: bootloader (then fastboot reboot-bootloader), the radio (then fastboot reboot-bootloader), then the boot (updated stock kernel), cache, system. Done, exit command prompt, then while in fastboot menu go into TWRP, whereby I choose system reboot and TWRP RE-ROOTS for me! Now I just kernel shop again

Thanks a lot gents. I followed the directions and upgraded/rerouted and none of my apps/settings got wiped. Yay!!
Can someone verify I'm on the latest versions for all components from my screenshot?
Thanks!

I also updated my Nexus 6 with 5.0.1, unlock and root, to 5.1 without losing data. I just had to re-root it afterwards.
I used Wugfresh Nexus root toolkit.
In short I used "Flash stock + unroot", in which I selected "Enable no-wipe" and "force-flash".
After this I rerooted the device from within NRT.
Worked like a charm!

Need help upgrading to 5.1, Tired of flashing all the things.

My nexus 6 is unlocked and is running stock 5.0.1, rooted. . It has twrp and is decrypted.
I tried to sideload the 5.1 ota but it doesnt work.
I tried flashing the new 5.1 factory image but that doesnt work.
I'm tired of all this now, I just want my phone running stock 5.1 , locked , encrypted ,unrooted so I can just get ota next time from Google whenever they send it out.
Any guidance on what I need to do would be appreciated.

Use Wug's Nexus Root Toolkit :good:
Edit : Now I'm currently "Optimising app..." loop.

I tried using tge NRT to flash it back to stock but it didn't work.

I would first make a TWRP backup, then I would flash the boot image (decrypted if you want and make sure its the new one), system, radio and then reboot. I flashed everything fine while keeping twrp on my phone but I didn't like not having a custom ROM plus it was a little laggy so I restored a TWRP backup. My phone did bootloop for a while but eventually it booted 5.1. I would be careful since 5.1 seems to be having some issues in general.

This got me out of the bootloop, successfully installed 5.1, and kept all my apps and settings. Good luck.

I agree that always works without fail and is much easier than a tool kit. I don't like tool kits because people need to learn the correct way to flash things before using one because its better to understand what you are flashing should there be an error.

I don't have anything against toolkits on some devices, so long as it is not used as a shortcut to learning the basics. That said, on a nexus, I don't really see any need to be honest.

Im a complete fastboot novice since this is my first nexus device (always had samsung phones up until now) and although I managed to root and unlock the boot loader I want to make sure I learn all the basics including flashing (side loading?) subsequent updates.
So Im currently rooted, unlocked bootloader on a 5.01. custom rom. How would I go about flashing the 5.1 update manually?
Im assuming that once I extract the update zip file I will find all the images that need to be flashed....what order do i do them in? How do I take into account the boot loader locking issue people have been facing that results in a bricked device?
Thanks in advance.
EDIT: I found this thread which outlines what I need to do http://forum.xda-developers.com/nexus-6/general/using-image-to-update-nexus-6-data-loss-t3053158
I only have two question now:
1. Im assuming the system image will wipe out the custom rom im on but not the data will leaving the data cause a problem? whats the command line to wipe data?
2. This doesnt address the boot loader locking issue causing a brick that people have been facing. This process involves updating the boot loader what do i have to do to make sure I dont brick my device?

You could simply not update the bootloader. Bare minimum requirements is update system and boot (kernel). if you want to learn more about fastboot, go to general > All in one guide > Question 28.
If you do not update the bootloader, you'll never get an OTA but it doesn't seem like you're wanting that anyway.
In regards to data, yes it could cause a problem if you're using a custom rom. You can use fastboot erase data command. This also wipes your /sdcard though.

Systemless root (Android 6.0) - Method for easy future OTA updates

I am looking for an easy way to be able to receive OTA updates after rooting with the 'systemless' root method, the steps I mention below assume that the system partition remains untouched after rooting. I have searched and not found a clear answer on this.
Would I be correct in assuming that this procedure should work to receive an OTA update and keep stock recovery after rooting?
Start with completely stock Android 6.0
fastboot boot twrp-recovery.img (boot TWRP, NOT flash, to maintain stock recovery after rooting)
Flash systemless root with TWRP
OTA arrives (Android 6.0.1 for example)
fastboot flash boot boot.img (with stock 6.0 kernel, root lost)
Accept & install OTA update
Success?
So unless I am missing something, this method would leave the system in a stock, unrooted state after the OTA is installed, and could be repeated for future updates. Anybody have any experience with this yet?

Sounds like it will work, but why mess with the ota? More work and risk honestly.
Since you're already using fastboot just flash the newest boot and system.img. Then flash/boot twrp and flash su like you'd need to do anyway. Done. You don't lose anything flashing system.

That is true, kind of just wondering/gathering information. It just seemed like with the new root method, OTA would be possible and less risky than before.

@quakeaz there is one step missing on your guide. After boot.img you also have to flash stock recovery.img. From Lollipop, Google is also checking installed recovery, and for successful OTA, it has to be stock as well.
Otherwise, your guide should work, I've done same thing with my Nexus 5 and 7 for like last 3 months.

Thanks for your reply, but I intentionally left that step out, due to step 2 in my list. By only booting TWRP, instead of flashing, I assume stock recovery will remain after rooting.

Ah, sorry, I overlooked that.
Since I have flashed TWRP instead of stock recovery, I'm going by same process as you write, just reflash stock recovery. And can confirm, that the process is indeed working (no need to install system.img, as with previous system-based SuperSU).

Sounds good!

Instead of fastboot flashing boot.img, you can use "Settings --> Full Unroot" in SuperSU. During SuperSU systemless flash, your old boot image is backed up. Among other things, the full unroot option will restore the backup, assuming it hasn't been lost due to a factory reset and whatnot.
On many firmwares, this procedure also restores stock recovery. This requires that both the firmware supports recreating the recovery from the boot image plus a patch file (most do), and that TWRP did not remove said patch file (which some versions do).
That being said, if you're using fastboot anyway, flashing boot, recovery, system and vendor manually is always the safest thing before an OTA.

Thanks for the info. So I take it while using systemless root, installing ota without unrooting is a big nono? The January ota just downloaded and is asking me to install, should I do it manually?

On many firmwares, this procedure also restores stock recovery. This requires that both the firmware supports recreating the recovery from the boot image plus a patch file (most do), and that TWRP did not remove said patch file (which some versions do).
That being said, if you're using fastboot anyway, flashing boot, recovery, system and vendor manually is always the safest thing before an OTA.

Thank you for this thread and the procedure. I tried myself to avoid as much as possible to use a computer for super easy OTA update. But there is always one obligatory step: to root the phone.
Phone systemless rooted (2.66) - TWRP installed - OTA arrives.
In SuperSu app : Fully unroot
Install OTA - success
Fastboot boot (or install) TWRP
Flash superSu 2.66.zip
And that's it!
My question is the following: Does it exist a possibility to load on step 3. something that could flash superSu.zip from within the phone, no computer required?
Maybe FlashFire? I guess not, for it needs root and the point is to flash a rooting zip... You see the loop there...
Would it be theoreticaly possible at all?

Yes, this is one of the use-cases of FlashFire. I just haven't finished updating it to 6.0 yet.

Oh nice!
I didn't know it cause I never had the chance to try out FlashFire.
Thanks so much for everything you do for the Android community!
Cheers!

Ah, sorry, I overlooked that.
Since I have flashed TWRP instead of stock recovery, I'm going by same process as you write, just reflash stock recovery. And can confirm, that the process is indeed working (no need to install system.img, as with previous system-based SuperSU).

Did you modify system?
Try flashing system, boot, and recovery.
Then try again.

Hi, I have a Oneplus One and today has been released an OTA, so I tried the method. I have COS13 JK (latest full rom) firmware, with systemless 2.84beta supersu and twrp.
The only apps that have root access are AdAway and Greenify (without mods to system apps). No Busybox installed.
I reverted via fastboot to original JK boot.img and recovery.img, and restored, via Adaway, the original hosts file, then I applied the OTA via stock Cyano Recovery, but update failed ("system partition has unexpected contents" error).
Why?
Thanks.

you have to unroot first from the app.Revert to original boot. and then flash

I tried: no way to install OTA, I had to wait for the full rom, and dirty flashed it via TWRP without a problem.
Then I rerooted.
Bye!

ok i seem to be getting the run around on where i need to be to ask my question(s)
i am very interested in systemless root....
that being said i am clueless and all info i am findingis just super confusing me.
if someone could humor a noob to systemless rooting that would be greatly appreciated!!
i recently bought 2 new phone for my household, both are the lg tribute hd (also called lg x style)
one click root and pc method of kingoroot etc dont work... i cant locate a twrp or a cwm for this model easily by searching so i am assuming there isnt one (maybe someone could located or help to build one?)- or maybe im not tech smart enough and i can use any?(i dont think so)
model is lg ls675,android 6.0.1, kernel version 3.10.49, build # MXB48T, software is ls676zv3
main reason at the moment for trying to get root is to remove bloatware and to be able to wifi tether without limitations buy the provider, on ther phone that i have obtained root on i used an app called WIFI Tether Router which works beautifully but requires root...
please help as this is how we use our computer with internet and its beneficial all the way around especially to get rid of bloatware and keep device running smoothly...
thanks again for any help. greatly appreciated.
if im not in the right thread please kindly direct me to the correct one. thanks

You are already on 6.0.1 Marshmallow. You said it yourself. You said you even still have stock recovery. So, seems like you don't need to do anything?
Maybe you wrote something wrong or left something out? Please clarify, and we'll be glad to help if we can.

OK, then you need to flash this via RSDLite or ADB.
[FXZ] Official Stock Firmware 6.0.1 MCG24.251-5-5
https://forum.xda-developers.com/dr...-official-stock-firmware-6-0-1-mcg24-t3569334
You can google how to download/use RSDLite or ADB. But that's the most recent stock firmware you need to flash with either of those tools.

i've tried RSDLite but it was unable to detect the phone(drivers was right and phone was in recovery).
i will try ADB than. with ADB should i flash every partition manually?

As far as I know you need to be on the bootloader screen, not recovery screen. Maybe that was your problem? RSDLite just automates a bunch of stuff ADB does.
Also, sometimes you need to use msfastboot instead of fastboot commands. I sort of remember why, but I don't want to state anything incorrectly. But try msfastboot if fastboot doesn't work.
For ROMs I use TWRP, so I'm not an ADB expert -- but I have used it. However, it's been over two years since I've had to flash a full firmware image via ADB (but I have flashed individual elements since then like modems, boot logos, etc.), so I'm just going to say yes flash every partition manually.
