CE and Radio ROM update only, no extended ROM, how please?

---

I want to keep all the O2 stuffs intact, is it possible to update only the CE and Radio ROM but not the extended ROM? I know the procedures I think, and I just need to delete ms_.nbf before running BaUpgradeUt? Will my O2 extended ROM stays intact this way?

How much better is 1.06.2 Radio ROM better than 1.02? Is it worth the update?

And after the update, I should just restore DATA but not full restore right?? Also, do I have to disable ActiveSyn before the update? If so, how?

Sorry about so many questions :P

Think ur ext rom will be blank this way

My answer to your question would be

Unhide the extened rom as is
unlock extenedrom as is now
make a copy of it as in on your desktop
do the normal upgrade
unlock/unhide the new extended rom
delete the content
copy from the destop your old extenedrom
lock/hide the exteneded rom again
do a cold reset.

this will boot the device, reinstall the os and radio and install the old extenedrom.

Do I think that that is a good idea, NO!! but that is what you want to do.

You need to undersatnd that some of the stuff on extened rom is for the new upgrade such as the patches.

So ... not that you asked ... I think what you want to do is swap only some of the files. but do you know which ones?

Read the bit on unllocking the Imate extenede rom
Read the bit about changing boot imaages.

Think about what you realy wont to do and have fun.

pleun, says:

Think ur ext rom will be blank this way

but it's not true. I've done that and your Extended ROM is not deleted

so:

1. You chose the ROM you want to use it (and you use xda3nbftool.exe if the ROM comes from another operator than yours)

2. Before launching the ROM installer "BaUpgradeUt.exe", you remove the Extended ROM package which is call "ms_.nbf"

and you update your ROM normally

Only the CE ROM and Radio will be upgraded. Your Blue Angel will keep your old Extended ROM.

And remember: If the ROM you have chosen comes in a package like BA_WWE_BelDT_12200_557_10602_SHIP.exe, you can open the ifile with WinRAR to extract its contents.

Simple solutions for a simple world!

True, only Qestion I have is why did I not Know that before?

Yup its simple and it works.

Now a real qestion for you based on you own knowleage.

Is there any way to add a Romkitchen Exteneded rom to the upgrade?

We seem to have know tools for this er2003edit does not work for me on the blueangle.
I have not been able to find any way of extracting splash screens but am able to replacing then (which is great but I dont have the original splashes)

Things are not only you know, your ways are not always the best.
