What happens to the Ext ROM when shelltool is used

[seacoug]

Hello all,

Thanks to that make this site available to people like me.

I have a Cingular branded phone (IPL 2.25.0001) that is considering using the shelltool. But before I do I want to make sure I don't lose functionality. It is my understanding that the Ext ROM is untouchable even if you pay to have the CID lock removed. How does this affect the new ROM put on the phone? It is my understanding that there are register tweaks etc that are placed there by vendors?

Thanks in advance

Hi there,

First of all, welcome :)

Now, the CID lock has nothing to do with the Ext Rom. The Ext Rom is sometimes part of a ROM. Shelltool only flashes OS part of the ROM, so your already existing ExtRom is not modified.

And yes, the vendors put there all the .cab and fixes needed (which might not be all the fixes there is :P)
