Q- What if you're accidentally deleted your Android (Oreo or any Android) updating package file (rom).

What is a Rom?

A “ROM” is the operating system software that runs your Droid. It is stored in the “Read Only Memory” portion of the hardware on the Android smartphone and/or tablet. All Android devices come with a stock ROM installed by the manufacturer.

What are the requirements of updating and upgrading your Android?

While updating and upgrading your android device you should charge your phone atleast 60% because low battery may results shutdown during installation period which cause harmful results eg: hard bricking and Soft bricking.

Failures of updating and Upgrading:

Sometimes we are in a hurry to update our device and so we forgot the above rule, then we downloaded the update file and when we are going to install it,the installation aborted due to this you may face total loss of the update file.

In this condition you will have to charge your phone to the required percentage then try again the installation if your update file is still alive or if it is gone then you will have to download it again instead of this you do not have any other option.

Conclusion:

Downloading an update file is not a big problem,you can download it whenever an update will come or go to the official website of that brand whose smartphone you're using. In official websites you will get all the latest and oldest files(firmwares) for the installation.
