[Q] Error with OTA updata to 5.1.1 : Kindly advise - Nexus 5 Q&A, Help & Troubleshooting

I am on Android 5.1.
Stock with stock recovery
Root with CF-Auto (unlocked bootloader)
No other modifications of any kind.
I am unable to update with the OTA 5.1.1 (from 5.1). When the phone is rebooted while trying to do the install. I just get an ERROR (with an android lying down picture). Then the phone takes a while before it restarts back to the previous setup. I've tried formatting cache, but to no avail.
I was able to update to Android 5.1 from 4.4 (4.4 to 5.0 and then 5.0 to 5.1) by just doing an OTA update and then using CF-Auto Root to root.
Can someone please help? I know the easiest way would be to wipe the device and flash everything. But I don't want to lose all data.
Is there any way to apply the 5.1.1 update without wiping the device?
Thanks so much in advance.

[Q] Trouble updating to 4.4 (Rooted / CWM)

Hi xda,
Can anybody help me in updating my shield to the latest update 72? I have a rooted NVIDIA Shield on (I believe) update 68, Android 4.3 Jelly Bean. I have clockworkmod recovery installed as the bootloader. Upon downloading the update and hitting restart, it brings up CWM and asks if I want to flash the update zip it downloaded, click yes, says root may have been lost - fix? click yes/no, doesn't matter I've tried both and then it boots right back up and says the system update is still available. SO it's obviously not installing correctly.
Can anybody help me out? Is it possible to install the OTA update with CWM, or do I have to restore the default android bootloader? And if so, do I also have to unroot? Factory reset? What would be the easiest way of updating?
Thanks in advance, I'm loving my Shield!
You will need to revert to the stock recovery before you perform the update, as CWM cannot do it for some reason.
If you are not using CWM features outside of rooting, you might prefer this rooting method which does not require installing it so you can just do OTA upgrades without worrying:

Failed OTA with a twist...
I also tried the OTA with a rooted/CWM Shield and failed. However, I found this thread and reverted to stock recovery as instructed. But now, it says there are no updates available, and still reports I'm running 4.3. So how do I get it to update?

I actually had the same problem as you after reverting back to stock recovery. The only solution I could find was to 1) Backup everything on my Shield and 2) Factory reset. After factory resetting, the OTA update was detected, and installed flawlessly. I'm now on 4.4 Kit Kat, stock recovery, and am in the process of restoring all my apps and then re-rooting.

Just an update:
After going back to stock recovery, factory resetting for the OTA update to detect, installing it, restoring all my apps, and re-rooting using the method above, everything is running great. Future OTA updates with ease as well as being able to have root access!

[Q] How to downgrade from Lollipop 5.0 back to Kitkat 4.4?

Recently upgraded to Lollipop 5.0 and it was a huge fail. Many of my apps are still unusable by this system. Is there anyway to downgrade it back to KitKat 4.4? My phone is clean, no roots or anything of the sort. Thanks in advance!
Unlock bootloader (wipes all data) and flash factory image. Only way

[Q] Help Req: Updating Rooted/CWM MotoG to Lollipop

Hi,
I have a UK Moto G (2013) running 4.4.4 KitKat and I installed CWM recovery and rooted it some time ago. Now they are pushing out Lollipop OTA I am getting nagged by the phone to update - but, it always fails when I try. Presumably this will be because of the CWM and/or root. I tried a full unroot but that didn't help as CWM kept complaining on the upgrade reboot about something (can't remember what now!). I've read that in order to get the OTA update to work, I have to get the phone completely back to stock, but I can't find a working stock recovery for it. Do I have to take it back to stock or not ? Either way, would anyone know how I can get the OTA update to work please ?
I've tried flashing a couple of stock recoveries, but one fails to flash at all and the other doesn't work - you choose recovery and it just reboots the phone.
At the moment it's back to rooted, unlocked bootloader and CWM recovery.
Any help you could offer would be very gratefully received.
Thanks!
Are you able to locate the phone's from here: http://www.filefactory.com/folder/c6cdedc45a775d27/?sort=filename&order=ASC&show=100&page=1

S5 5.0.1 Update OTA or Odin?

I have a Galaxy S5 and it's on 5.0.1 Stock not rooted or Custom recovery. I want to install Blisspop 6.0.1. How would I go about doing this? Is it ok to install the 6.0.1 OTA and still be able to root and install custom recovery?
Edit: Ended up just OTA. Mod delete thread please??
It's probably easiest to update OTA, since it will preserve your apps, data, & settings. I wrote a step-by-step tutorial on how to update OTA to 6.0.1, install a custom recovery, and root. Here you go...

I believe blisspop is still based on 5 firmware. If you update you'll just have to go back to OK4 firmware to run it.

Can I update from 5.1.1 to a custom 6.0.1? How to keep data?

Hi,
I want to update to 6.0.1 Xtresolite but I wonder how can I keep my data? (I want to restore every apps & images on the updated version)...
When I update, should I make a factory reset? When Can I find a step by step from 5.1.1 to 6.0.1 ?
What do you think about Smart Switch?
When you are coming from 5.1.1 stock you can't install a 6.0.1 rom. You first have to upgrade to stock 6.0.1. Keeping data when flashing a custom rom is unlikely since a full wipe is required before flashing when you don't want to run into any issues/FCs.
@XxM4tzexX So I can update to 6.0.1 stock without loosing any data? How?
Flashing a stock Firmware via Odin.
