Instead of having instructions all over the place inside various threads I felt a clear guide should be available as it's own thread. Now since Google implemented this great feature (all hail google) where normal OTA's no longer work on Nexus devices with Android 5.0 that isn't 100% stock i.e. rooted with or without custom recovery a lot of people don't know how to update their devices.
IMO opinion the easiest way without losing any data is to use Fastboot and this is an attempt of a how-to-guide. This is made on a windows PC, probably works with other OS's too.
What you need:
1. You need ADB.exe and fastboot.exe inside an easy accessed folder i.e. put in c:\ADB.
The easiest way to get these are with this tool: http://forum.xda-developers.com/showthread.php?t=2317790
You can also get this by installing the whole Android SDK but that is just a waste of bandwidth and time.
2. You also need to download the latest factory image for Nexus 5. Do this here: https://dl.google.com/dl/android/aosp/hammerhead-lrx22c-factory-0f9eda1b.tgz
3. You might need adb drivers but you'll have to find instructions for this by yourself.
The procedure:
1. Extract necessary files. The factory image you'll download is named hammerhead-lrx22c-factory-0f9eda1b.tgz
This is an archive which can be opened with an extractor of your choice e.g. 7-zip
Inside this archive is another file with no file type extension. Extract this file and rename it to whatyouwant.zip since it's a regular zip file. Then extract all files within this file (very meta with zips inside zips inside zips etc).
The files you need for updating with fastboot are:
system.img
boot.img
radio-hammerhead-m8974a-2.0.50.2.22.img (rename this to radio.img for more convenience)
put all these files in the ADB folder (it will make things easier).
2. plug your phone to your PC. You need to have USB debugging activated in developer mode.
3. open a command prompt and orient yourself to the adb folder (c:\ADB)
4. type adb reboot bootloader and wait until your phone is in bootloader mode.
5. type fastboot flash system system.img and wait until it's finished.
6. type fastboot flash radio radio.img
7. type fastboot flash boot boot.img
8. reboot your device (type fastboot reboot).
Hopefully this will work and you will update without loosing any data. Then you can proceed with rooting, flashing custom recovery etc. This is easiest done with WUG nexus root toolkit (http://forum.xda-developers.com/showthread.php?t=2389107)
I couldn't find any other guide's but if there's already one please remove this.
Just a note, you don't need adb.exe at all, and the drivers are actually USB drivers.
Its also worth noting that 95% of us prefer to recommend users not use toolkits.
Also, you could simply say:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash radio radio.img
...then point them to the existing adb and fastboot thread which would have saved you writing all the installation stuff out.
Thanks for the guide @mertzi. I've just used to upgrade my Nexus 5 to 5.0.1 without any loss of data. I appreciate the help!

Do I still use "fastboot flash radio radio.img" even though the radio image from the tgz file is "radio-hammerhead-m8974a-2.0.50.2.22.img"?

No. The 4th section is the file path and location.
So this keeps user data? Just updated the system to 5.0.1?
Maintains root and all?
Sent from my Nexus 5 using XDA Free mobile app
Keeps user data but you will have to re-root.
Thank you, thank you, thank you.
I've spent last couple days trying to make heads or tails out of other "tutorials". Some of them linked the OTA update and gave instructions for full image, others gave instructions but lacked the links to the image. I am surprised that none of my searches took me here until today.
Thanks a lot for this guide I was ale to update to 5.0.1 thanks to this guide.
Can I use this method to update from 4.4.4 to 5.0.0 ?
... Not aire if you can jump from 4.4.4 to 5.0 this way...
I actually jumped flashing radio and baseband and THEN flashing CM12.1

I've looked all over, but cannot find anything on the problem I am having.
I go through the steps to load the current factory image onto my nexus s 4g through terminal on my mac, but for some reason it doesn't load everything. Here's what it says in terminal about the items that can't load:
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
And here's what my folder looks like where I'm loading everything from:
I guess I can't post a picture from an outside source, so I'll just type in what my folder looks like:
boot.img
bootloader-crespo4g-d720spric1.img
flash-all.bat
flash-all.sh
flash-base.sh
image-sojus-jro03r
image-sojus-jro03r.zip
radio-crespo4g-d720sprilf2.img
there are files in the unzipped folder (image-sojus-jro03r) named:
android-info.txt
recovery.img
system.img
userdata.img
These seem to be some of the files that are missing, but even when i drag them over to the main folder, they still don't load. maybe something to do with the fact that they are .sig's?
I drag the flash-all.sh file into terminal and it loads and writes everything except for these .sig's, which I truthfully don't know what they are. Now I can't get into the correct recovery mode, it just shows some weird blue-lettered options that are different then the normal recovery options. That is why I think the fact that these .sig files are not loading is the problem.
I also booted up the new operating system and signed on, but for some reason none of my apps can download.
Sorry for my noobness, but I'm sure I'm missing one easy step that will fix my problems.
Does anyone know what I'm going through?
Any help is much appreciated.
Alright. I've searched the web and found a few different things. It seems that it's common for those .sig files to not load. Also, i loaded the factory image again and was able to download my apps.
I also now foolishly realize that to get a good version of recovery, I need to root my phone. I'm in terminal now, and for some reason adb is not showing my phone in adb devices. This wasn't a problem when I loaded the factory image, but now it's a problem when I'm trying to do this: http://forum.xda-developers.com/showthread.php?t=1129759
step 5 is a problem, but hey, I can turn off the phone and go into fastboot mode myself. I guess step 7 is the next problem I'm dealing with. Here's what I get in terminal when I do step 7 manually (I put a *#* where my name is just so everyone knows):
MacBook:~ *#*$ /Users/*#*/Desktop/adb-fastboot/recovery-clockwork-5.0.2.0-crespo.img
-bash: /Users/*#*/Desktop/adb-fastboot/recovery-clockwork-5.0.2.0-crespo.img: Permission denied
Does anyone know what I'm dealing with this time around?
You probably need to enable adb in Settings --> Developer Options. If it's an issue with adb while in recovery, i'm pretty sure the stock recovery (which will be overwritten on every boot from a stock ROM) doesn't allow it. What you need to do is flash a new recovery in fastboot (not in recovery).
Commands (while in fastboot mode):
/path/to/fastboot devices <-- this will tell you if your phone is connected properly
/path/to/fastboot flash recovery /path/to/recovery.img <-- this will flash the new recovery
You'll need to type in the path to fastboot unless you have it in somewhere like /bin or a more convenient environmentally recognised location. The command you typed there is the same as trying to open the .img file as a script, you want to tell fastboot to flash the file to the phone and not open it with the computer.
Edit: Also, once you root, you probably want to delete /system/etc/install-recovery.sh. That file replaces any custom recovery with stock each time you boot.
Thanks Harbb.
That's what I ended up doing, using fastboot. it worked perfectly. I did try to find the /system/etc/install-recovery.sh file in root explorer, but could not find it. don't know where it is.
Everything is rooted and restored on my custom rom to where I was previously using titanium backup.
Here's the tutorial I was using: http://forum.xda-developers.com/showthread.php?t=1129759
with this video being a walkthrough of the previous tutorial: http://www.youtube.com/watch?v=sP9ZDWmbLVM
I was actually using the recovery img in the android folder that I downloaded from the tutorial, and not the one he told me to download, which was my problem in the end. Here's the link to the download page where I should have downloaded it from: http://forum.xda-developers.com/showthread.php?t=988686&highlight=clockwork+4.0.0.2
Thanks again Harbb, much appreciated.
No worries buddy, glad you got it sorted.
Hi,
I read that once I will root my phone I will lose over the air updates. But how to manually update it? I use CWM. And will i need to reroot the phone after the update?
Thanks in advance!
Just flash the 4.4.4 zip in recovery. Don't wipe cache or anything. You won't lose data or root, you might have to flash super user in recovery after. I have survival mode on in super user and did not need to reflash su. The zip can be found here http://forum.xda-developers.com/google-nexus-5/development/rom-stock-4-4-3-ktu84m-odex-deodex-t2771010
You will not use otas if you rooting. You will get otas even if you are on a cm rom.
Here is how ota works:
Cheks those system files which have to be updated. If any of those system files is different, then the update fails and will show you an error about unexpected content in xxxx file. If every system files got checked and they are all good for the ota, then it starts patching the files. Then it flashes bootloader (if any), modem (if any), kernel (if any) and copies the recovery image to /system and a script to /system/etc/ then the phone restarts. At booting the phone flashes the new recovery and done.

Install SDK, and make sure that /platform-tools dir is in your PATH (environmental variable) so you can use fastboot and adb from cmd line. Then
1. Download the factory pack from Google
2. Extract it (you can use winrar/7zip, or whatever)
3. Edit the Flash-all script (remove the "-w" if you don't want it to wipe, and the line to flash recovery if you want to keep CWM).
4. Boot your device into bootloader mode, connect via usb
5. run the cmd "fastboot devices" to check your computer see's your device, if not.. you need to configure your drivers
6. run the Flash-all script
That's it.
What is the advantage in doing all those extra steps when you can just dirty flash 4.4.4? I know for a major android version upgrade you'd want to do a clean install, but this is such a minor one. And please don't say something like....to learn how to use fastboot commands.

Those instructions don't require you to know any fastboot commands (the script automates them).
Bear with me: Right now my nexus is stuck in a bootloop. My nexus had been partially rooted, everytime i went to download the OTA 5.0.1. update it would just take me to TWRP, and i didn't know what to do with that. So I finally tried to fully root the phone, and also use TWRP to install the OTA update. Now I'm stuck, I've tried wiping the cache/factory reset. How do I got about flashing it back to stock without losing all my data?
(apologies for the title, I thought originally that I had killed mtp and adb, but I figured out how to get them back just after posting)
Thanks!
As I saw your post before the edit.... Stop using toolkits and read about adb. If it's bootlooping then it's 95% not bricked so don't panic and read the guides
Just download system.img you want and fastboot it
Edit -
Don't see this as me being mean or a ****. This is stuff everyone needs to know, it's really not hard at all so don't worry. Once you've used it a few times you'll wonder why you ever used toolkits

I don't think you're being a ****. I'm very grateful for your input. I used to be very into jailbreaking when I had an iPhone, but i haven't been able to put the same time towards getting the hang of rooting (which I think has a steeper learning curve to begin with|). I sort of understand adb but I obviously need to learn more. I've been using the toolkit because it was simpler. I remember from trying to use adb before that I need to place the files I want to transfer in the same folder as adb (i think?) but I could never get that to work.
I also don't understand system.img.'s relevance here. I'm not getting the "Error: Update package missing system.img" error.
The reason I say read the guides is simply it saves me or anyone else typing out a massive guide that already exists in many places.
If you're looping then something is more than likely wrong with the system not the data. So flashing just the system will keep your data safe (as long as you flash the same android version as you previously had, lollipop or kitkat)
You need to be in the bootloader not recovery and use the command fastboot flash system system.img
Google img's are here - https://developers.google.com/android/nexus/images
(just keep unzipping until you find the individual img files)

He's saying to flash a system image to get you up and running again, and I agree that that is what you should do. As far as placing the files in the same folder as adb and fastboot is concerned (you'll use fastboot to flash the image), you need to do just that. I created a folder on my desktop called "ADB" and that's where both adb and fastboot are, as well as all the files that I flash with fastboot ie. system images, recoveries, etc... Here's a great guide to get you going with adb and fastboot- http://forum.xda-developers.com/showthread.php?t=2277112
Now when you go to flash it, if you decide to use the flash-all.bat to flash everything (the full factory image) and bring you back to stock, you'll have to open the .bat file with a text editor and remove the "-w" from the script and that way it won't wipe your phone. If you want to just reinstall the OS without everything else (worth a shot), just flash the system with the command
Code:
fastboot flash system system.img
and that should get you running again. If what I just said is confusing, read the guide I posted and it should become clear.
Here is where you'll download the factory image from- https://developers.google.com/android/nexus/images
Just unzip it, pull the system.img out and place it in the same folder that fastboot is in and flash away.
And one final thing- definitely avoid toolkits at all costs. You spent a good chunk of change on your phone, take the time to learn how to mod it the correct way.
Good luck!

So I have adb and fastboot running. And I changed the flash-all.bat file. However, I don't understand what I do now? I downloaded the Hammerhead zip and it has a bunch of things in it. Which files do I put into the adb/fastboot folder and how do I then flash them?
In the hammerhead file it lists the bootloader, flash-all, radio and then a zip file "image-hammerhead...". What files am I using and what is the code that I input? Is this the same sa flashing a rom?
I also tried placing the system.img in the adb folder, and then using the
Code:
fastboot flash system system.img
but it gives me an error "cannot load 'system.img'
So now my issue is I get a "error: could not load 'system.img'. after running
Code:
fastboot flash system system.img [code/] . I also tried with boot.img. Same error.
I ran the "flash all" script, by accident, a screenshot of the terminal is attached.. I'm still stuck in a the boot loop, however, and if try to enter recovery mode an android lying down with a red triangle is present. The above "error: could not load..." is still present.
Create a folder and put fastboot in it.
So you unzipped the stock image. You said you have some images in the folder and a zip image.
Unzip that second zip.
There you will find the rest of the images you need.
Now take the recovery, bootloader, system, userdata, cache, and radio images and move them into the folder which you created for fastboot.
Rename the bootloader image to bootloader. img
Now when looking at that open folder containing all the images and fastboot hold down shift and left click and select "open command promt from window"
Type
/fastboot erase bootloader
/fastboot flash bootloader bootloader.img
/fastboot reboot-bootloader
/fastboot erase recovery
/fastboot flash recovery recovery.img
/fastboot erase radio
/fastboot flash radio radio.img
Repeat for the rest of the image files
Finally type /fastboot reboot
Profit.

Oh and that android is stock recovery
U fixed it?
So for some reason I still kept getting that error. I ended up restoring to stock using the nexus root toolkit. So it all worked out in the end.
pretty much says it all, its been a long long time since ive flashed anything ( and the last time i did something it didnt exactly go to plan )
Ive got a Nexus 5 (32GB) its rooted with team win recovery and i would like to update it to the latest version, preferably without losing any data
ive tried searching but there doesn't appear to be a simple guide on how to do this
any help would be greatly appreciated thanks.
There's a whole thread on ota's in the general forum. Start there. You have a number of different options. It would also help to know what android version you're on now.
Sent from my Nexus 5 using XDA Free mobile app
Your Nexus 5 is rotted?
Its not rotted yet, however my typing skills probably have.
Android version 5.0.1
just tried downloading the OTTA update and renaming it as update.zip
then adb sideload with adb sideload update.zip
then error : closed
and thats that.
the guides says this:
Scenario #2
You are stock, with root. Custom Recovery without any modifications or deletions.
Continue to Section B
Click to expand...

OK, so on to section B as advised
Section B says
Section B: Flashing in a Custom Recovery (TWRP- CWM)
(For Flashing 4.4.4 OTAs and Below ONLY!)
1) Download the OTA.zip and copy to your phone.
2) Boot into recovery.
3) Flash the OTA just like you would a ROM.
4) Reboot.
Click to expand...
Click to collapse
Im on 5.0.1 so thats that out of the window
Download the latest Factory image.
Download the Android SDK.
Boot into bootloader (Vol- & Power). Connect the phone to your Computer. Check for exclamation marks in device manager.
If there are some install the drivers. If there are none extract the contents of the SDK. Copy the contents of the extracted factory image into the same folder (into platform-tools).
Open up the command prompt, by typing "cmd" into the search in the start menu. Once you are in cmd you can change the current folder with "cd" (cd .. gets you out of the current folder and into the above one, path wise / cd foldername enters a folder). "dir" lists the contents of the current folder.
Navigate to your SDK, into the platform tools folder.
Open the flash_all.bat (DO NOT DOUBLE CLICK, do a right click select edit). Type these commands one after the other (just the stuff starting with fastboot). So you flash the new bootloader, reboot, flash radio etc.
The latest fastboot has a "-w" in it. Leave that "-w" out, otherwise you will wipe your device.
Congrats, you flashed a factory image.
If you only want to flash parts of the "image-hammerhead.zip", extract it. It will have several .img files. You can flash these with "fastboot flash "image Type (system/recovery/data)" "filename.img" (without "" of course).

IMPORTANT NOTE ABOUT ROOTING AND UNLOCKING BOOTLOADER:
After flashing TWRP 3.0.2, use the SuperSU 2.46 flashable zip, do NOT use latest version or will result in a bootloop. Good Luck and have fun with rooting. Unlocking bootloader will delete all your data, so please make a backup first. Thank you.
----------- -----------
CREDITS
And also, before anything i would like to say thanks to @arjaylzo for telling me the name of a device with TWRP which helped making this update possible.
REQUIREMENTS
1- Fastboot/ADB Drivers and ADB folder
For drivers: http://adbdriver.com - Download ADB Driver Installer (universal) from the website, extract it, connect device it should detect device(if not, enable USB Debugging and reconnect), and press install, it should install drivers.
For ADB Folder: download this and extract to your main drive(C:/): https://goo.gl/ZTrfBb
2- Unlocked Bootloader (you need requirement 1 to do this)
Instructions for Unlocking bootloader: Go on settings, about device, press build version several times till it says your a developer, go back to settings, press Developer Options, and enable OEM Unlocking. Power off, then press at same time Power and Vol+ button, then connect to pc and open a cmd and write cd c:\\adb and write fastboot oem unlock, then accept the prompt it will give on tablet, and follow the rest of the steps.
----------- -----------
New TWRP bugfix update! Now you can flash stock rom on TWRP without bricking! Download Page updated!
----------- -----------
BUGS:
1- adb shell command needs to be sent before system partition is mounted or it will give an error, after doing adb shell you can mount system and do all the modifications you need.
2- You cant flash any img on twrp it gives an error, im trying to fix.
3- Backups do work, but everytime twrp restarts, the device name seems to change (which means that on /TWRP/BACKUPS/devicename/backupsinside/ changes every reboot so you have to go get the backup inside the old devicename folder and put on the new devicename folder).
----------- ADITIONAL NOTES -----------
Im leaving an unsecured boot image because system seems not want to boot android if anything seems changed. So please if system does not boot after flashing twrp/rooting, flash the unsecured boot img on fastboot
----------- -----------
Steps TO INSTALL TWRP AND ROOT
1. Download and extract the files: https://drive.google.com/file/d/0BxzG5iupOOSKNTdlRC1Wd0VmTlk/view?usp=drivesdk

make sure you didnt put a folder inside the adb folder instead of the actual file and make sure your writing the right name of the file..

If you flash stock rom, i think you have to reinstall stock recovery, the rom itself already brings stock boot.. after flashing stock recovery it should boot since no modifications have happend
Wow good job! Now i have a recovery where i can flash my custom rom for the Predator 8.

On step 4 You need the fastboot files, (adb & fastboot) just search how to install adb and fastboot drivers, choose the directory where to install them and place the needed files inside that folder and open a command prompt on that folder so you can flash the files.

ir I tried finding how to install fastboot driver on Google all showed me downloads links must do survey or download or purchase item to unlock the download files ... So I don't trust it so I kept searching "how to unlock fastboot Acer predator 8"
So for ADB I can search on Google and install it on my tablet ?

no, Search how to unlock bootloader, it should show the method that works for most devices and give necessary drivers..

Yes, and after you unlock the bootloader, you put the necessary files in adb folder and flash them according to the stepts
Ruben Craveiro said:
C:\adb is where my adb and fastboot commands are.. on the downloaded files from Step 1 only the SuperSU zip is needed on the tablet so that you can flash it later on with twrp, the rest you leave on pc and use fastboot to flash TWRP, unsecured boot image, etc...

That means adb drivers arent corrently installed, but i can see you have the folder with adb, all you have to now is download this(drivers): http://dl.adbdriver.com/upload/adbdriver.zip
Extract and open the software eith the tablet plugged in, it should tell of drivers is installer properly or not, and if not you can install, after installing it should work on the cmd the commands..
