[Q] Question regarding rooting Nexus 5 and subsequent upgrades

Hi all,
Looking for some advice please as a newbie to Android.
I have a Nexus 5 32gb on order that is being delivered any day now.
My assumption is that when I turn it on, it will have Android 4.4 installed as default.
I intend to immediately root my device prior to setting it up with all my personal data etc.
My questions are:
Do I install the 4.4.2 update OTA prior to rooting the device? I imagine this would make the most sense as there may not be further updates for a while - is this right?
If I do install the 4.4.2 update OTA and then root the device - for future updates, do I then have to install a 'Custom Rom'? - for example if/when Android upgrades to 4.5
Are there some good guides showing how to install a stock/vanilla Android upgrade?
If/when I install a 'Custom Rom' of 4.5 , what would happen to my root priviledges? I assume they would disappear? what then?
Is there a good repo/site for stock/vanilla Android OS?
Many thanks in advance,
litfoo

You'll want to first update to 4.4.2, as it will save a bit of time.
What happened with my Nexus is I rooted it while on the 4.4.1 update, and then when 4.4.2 came around, I was able to use OTA which installed it through TWRP. I had to re-root my device and reinstall TWRP after this.
There are guides on how to sideload OTA updates, which is a way to update android.
Most custom roms will come with root, so you may not have to re-root.

Many thanks for this .
So - once rooted, I can flash device with an updated Factory Nexus 5 image? If yes, I assume this will lose root?
If I wanted a custom rom of a factory Nexus5 image, but with root - where's the best place to find these and what are the most popular ones?

Can't update to Lollipop!

Hey guys, so I really need your help with this.
When I bought my phone it was on Kitkat 4.4.4, after a month, I got the Lollipop 5.0 update via OTA, updated and all ok, then after a while I got the 5.0.1 update, which had this major bug of memory leaking that kept draining battery like crazy.. So I kept searching on how to downgrade to Kitkat 4.4.4 and I followed all those steps to install Kitkat using fastboot/adb tools.. And it worked, I've been running Kitkat now for a week and it's amazing, no memory leak bug, no battery draining.
And just by curiosity, I tried to check the updates, but it says that my system is up to date.. I mean, it doesn't give me the Lollipop 5.0 update nor the 5.0.1.. What's up with that?
Does that mean that I can't update to Lollipop via OTA again? I just need some clarification about this if it is possible Screenshot has other information such as build number, kernel, etc..
PS: I have the CMW custom recovery installed, maybe that's what's stopping the OTA update?
Thanks guys ^^

The update isn't available to everyone all the time...it goes in batches..
Anyway you will eventually get the notification, but you wont be able to install it as you're modified. Anyway, no worries - you know how to do it manually now.

Lollipop update- where are you ?

About 3 weeks i installed the Kitkat rom stock on my N5.
Today i tried to see something about the OTA update to Lollipop, and surprisingly i saw isn't it arrived to me.
I just tried to Clear Data from the Google Services Framework- still the same.
Somebody know how can i get it ?
Thanks for answering,
Tal.

Are you rooted? If so, you'll need to unroot to take the OTA.
Sideload this via ADB: clickity-click.
Wait. I think you'll need to sideload the 5.0 update first, and then do the one I linked for 5.0.1. Can somebody confirm this?

First of all don't clear Google services framework data that messes up stuff pretty bad. Second d, this should be in q and a section. Third just flash the 5.0.1 factory images or there is a flash able zip out if you're rooted with custom recovery.

I agree wid op...
I have used kk for past 2-3 weeks... And notification never popped out...
I flashed manually 5.0 and i got ota for 5.0.1 ... I dont knw whats up wid google ota system...

5.0 ota seems pulled, Got 3 N5 which all have the ota prompt before, but none of them get the ota message now.

So isn't it only on my device. OK.
Thanks !!

It never was your device. The OTA is rolling out in phases (not sure it's true that it got pulled but I could be wrong)... Just flash the factory images or lollipop stock ROM flashable zip. There are plenty of threads about this in the stickies...

5.0.2 -> MD5 check fail

Hey guys,
I'm a bit fed up of android L for now with the endless bugs and connectivity issues I'm experiencing so I decided to downgrade to 4.4 again and patiently wait until 5 has been developed a little further.
How ever when I try to flash any given 4.4 ROM, all I get is MD5 check fail.
I'll quote the exact message later when I'm home but that's the general idea.
I'd really like to get back to the stock CM11S so I tried a ROM directly from Cynagogens website and also a few from here. The only one which did work was Carbon but I'm not a big fan of that ROM.
I read up on this and found that old versions of recovery don't work but I'm using the latest TWRP which according to some people should work.
For now when I try to flash 4.4, I do a complete wipe but still no luck.
Does anyone have any idea how to get back to stock OPO ROM?
Thanks!

The best way to get back to the stock ROM is by flashing the stock images with fastboot. This ensures that your ROM plus all firmware is lined up currently. Check section 8 in my guide thread for directions:

[Q] Last Resort... Need Help.

Phone: Motorola Moto G XT1032
OS: Android 4.4.4
Let me start by saying that I am new here, and I am not sure if this is the correct place to ask for help, but here I go anyway...
I am in desperate need of assistance. Against all better judgment, I rooted my phone a few months ago and now I am in a "pickle" so to speak. I recently recieved the Android 5.0.2 OTA Update notification. I have attempted multiple times to install this update but each and every time I do so, it returns me (after rebooting) a message along the lines of "software update was unsuccessful". I have sifted through some posts online with no avail. I am not the best person when it comes to my phone, however I do know how to get around on a computer.
I guess I should also add that I read somewhere that the phone must be un-rooted before attempting to upgrade, however, I have alrady attempted to do so with the "Full Unroot" option in SuperSu, but the only thing that seemed to have happened is the app is now deleted.
Another thing, I only rooted my phone and did not install any of the recovery programs like CWM or TWRP. This is stock android and no Custom ROM.
Any help would be greatly appreciated, as I have been waiting for Andoid L for a very long time and am very upset that I am having all these issues trying to use it.
Thank you for listening and look forward to seeing if anyone can help me.

What you may try to want to do is to find the factory stock image online for which ever version you have and run it then upgrade to each new version till you get to lollipop update. Yes you will lose all of your data but if lollipop is what you want that is probably what your gonna have to do. Every time a factory update is available on Motorola before it does the update it will check for every app and checks file system and recovery. Anything out of the ordinary and it will usually not upgrade it. So if I was you look for the stock factory image of 4.4.4 and update to lollipop 5.0.2.

Alternatively flash a custom recovery, TWRP or Philz Touch, and then do a factory reset and flash one of the zips in this collection:

Less risk and you keep your photos etc.
