I'm NEW AND I REALLY DON'T KNOW WHAT IS AN ExtRom!!

[stombacco]

HI, I've bought a JASJAR few weeks ago and thanks to you I've done many things. Unfortunately, due to my poor experience I guess I'm wasting lot of time in trying understanding things. The most important, is to understand exactly what is ExtRom and why everybody is doing theri own personalized.
THANKS TO ALL!!!

My laymans explanation, others may give a more techy one:

When you hard-reset the operating system and applications that come as standard are stored on a rom and are set back to factory settings. Some network phone provideers (O2, Vodafone, Orange etc) like to customise the phone with extra applications, tweaks and branded screen themes. These are usually loaded straight after the reset.

The main reason you are seeing so many posts about the ext-rom is that some people don't like these added extras (mainly as they seem to make the XDA slower).

The second reason is that the ext-rom can be used to store your own customisations so in the event that you have to hard-reset you can get your XDA back to it's current setup quicker.

It is a bit techy to do as the ext-rom is write protected and hidden.

So basically some are making it visible, write enabling it and adding cab files which are to auto run on a hard-reset.

Lastly, it may be usable as extra storage so watch this space for the best tweaks...
