security update

So i have the sprint 32 GB version and keep getting offered a security software update.
Since I have cwm installed when I try and install the update it takes me to cwm recovery.
Cwm recovery will not accept the signature and aborts installation
Anyone know what the update even does ?
Any way I can install the update without unrooting ?
Thanks

Will not update to Lollipop

I have been receiving a system update notification for about 2 weeks now and every time I try to install the update it reboots, goes to apply the update and then it reboots again like nothing happened. Anyone else have this problem or know a way to fix it? I have tried doing the update manually through adb sideload but it keeps running into an error there as well and aborts the install.
If the directions here http://forum.xda-developers.com/showthread.php?t=3030327 don't work for applying the update . I'd flash the TOT.
If you have twrp installed make sure to reinstall the stock recovery. The update zip cannot correctly flash its updater script. The stock recovery can due so, so I would install it.

Unable to update latest oxygen OS OTA

It downloads, reboots and tries to install the latest Oxygen update but fails and asks for a reboot.
At one point I installed Kingroot but removed it afterwards. My phone is also encrypted if that matters.
Thanks
having the same problem with my gf's phone...... was a 1003 model if i remember correct.... recovery just had an "Update Failed" and nothing else.... even flashing the full package failed........ i'm considering installing TWRP and going from there but i'd like to avoid that if possible

No recovery?

I think I f-ed up. I wanted to do a clean firmware install, so downloaded and installed the full OTA package from Firmware Finder for my current FW (C636 119).
The phone installed and boots/reboots/works fine. But when I try to get into recovery mode, I get an error message: installation failed.
Any idea what I can do? Will this affect future OTA updates?
