How delete a system update

[druizm]

Hi,

Today I have downloaded new 15.3.A.0.26 update. After download it, I have not installed it because I prefer read some forums about this new update... But, now, I don't know how I can delete 300 MB downloaded... Is there any way for deleting that MB and, when I want, download again this update?

Thanks.

Don't quite follow but close PCC or SUS and start all over

I have downloaded update from phone, not from PC using PCCompanion, so now phone is ready for apply update... but I want to wait some days until I could read in forums if this new update can "destroy" Android 4.1.2 (that is working fine!!!)
