/extended rom/

[adam79]

how do i get to the extended rom directory? i have a t-mobile mda and have total commander (reg editor) installed. I can't find the /extended rom/ directory and also don't really understand what is or what it is there for. i know this might sound like a remedial question to HTC Wizard experts, but if someone could help me I'd greatly appreciate it. Also, if it matters, I'm running xelecin's custom 2.26 ROM.
Thanks.

You won't see it by browsing.. just type in "/extended_rom" and TC will open it. Don't forget the underscore (_) character..

Gee - my first post!

thanks. i entered "/extended_rom" and it brought me to the directory. now that i know how to find it, what is it exactly there for? What is it's purpose. Also, can you access it from activesync? Thanks again for answering these questions.. i'm a beginner with PPCs, but I'm curious about how they work.
Thanks again.

Use the advanced search feature (under the search option tab) to look within the wizard updating forum for the term "extended rom", and you can start to understand how some of the rom developers utilize it (There are 12 pages of entries). These guys are the real 'wizards' - I could not begin to explain the way they do (I'm too new myself).

Your extended ROM contains all of your customizations. If it is a stock ROM it will have all of your carrier customizations. If you have a cooked Ext ROM it could have lots of things. One of the benefits is that if you have to completely clear out the storage it would re-install all the customizations that were in the ext rom.

so, in simple terms, if you were doing a hard reset (or clear storage in settings), the extended rom directory retains the files, and installs them if they are .cab files.. am I getting warm? Thanks for the info.

[barrydavisjr]

you got it. The carriers put it there so that one wouldn't have to call into tech support if you had to do a hard reset.

[adam79]

ok. i get this now. just a couple more questions..
-Do the .CAB files have to be in the main directory (/extended_rom/) or can they be in any subfolder?
-I was reading somewhere that it's a read-only directory.. is there a way to delete files, if so, can you delete the files one at a time or all once?
-finally, can you access the directory from active sync?

Thanks for all the help. I appreciate it.

As far as I know it is unable to be accessed through Active sync. And yes you can delete them off one by one. I would reccomend reading up on it. Faria has produced a wondrful guide on how to cook your extended ROM. When you delete a cab you also have to change the config settings in the notepad file. I have dabbled a little but Faria's guide will help you more.

!!!WARNING!!! if you delete the files from your ext rom and do a hard reset none of the carrier customizations will be installed.. furthermore.. you will not gain any extra space by deleting the cabs, it is a read only partition.. also with that being said, if you try to delete a file from there or add one you take a great risk of corrupting the ext rom and you will be forced to reflash the rom in order to get them back.

just one more question.. I have xelecin's 2.26 custom rom on my MDA. I'm thinking of switching over to either molski's or faria's latest rom. when i flash those roms, the extended rom from the current rom i'm using gets replaced with the custom rom's extended rom, right? does that make sense? Thanks for putting up with my dumb questions and actually answering them! Oh yeah, when i installed the rom i'm using now it did a CID unlock before flashing, so i assume my phone is still unlocked, right?
Thanks again for all the help. i really appreciate it.

thats right. - you'll get the new extended rom.

I only install a portion of the T-Mobile customization, which I accomplish by preventing the install of the extended rom. I have copied onto my miniSD the files I want to install, and then I just manually run the cabs from there. (Actually, that would erase them, so I copy them first.)

Then you can experiment with other ROMs, still getting the customizations that you need. Here is my thread on this topic:

I no longer install MP-Shorcut-MMS1-Voice-CV-TMUS-060404.CAB because that just adds MMS to the Messaging app and a shortcut for making voice tags and I don't use MMS.

By the way, it is really useful to install things like Total Commander, Memmaid, weather programs, RSS readers, Zagat, and so on to the miniSD, because then they don't need to be reinstalled after a hard reset. The only thing I have to do is add the shortcuts back, because shortcuts are erased after a hard reset. These programs will no longer auto-update, since nothing can run automatically from the miniSD, but with memmaid you can create automatic updates if you like.

Your backup program should always run from main memory! Also, programs that affect the today screen should also be run from main memory for increased speed. Pretty much everything else can go on the miniSD.
