Noob trying to upgrade to GPS working ROM

[nelsongruebr]

hey all!!

i'm from Venezuela and i recently purchased a HTC PPC6800 (cdma) and my carrier here didn't activate the GPS...

I'm not new to windows mobile but i'm totally new to ROM upgrading...

the only thing im affraid of is not being able to make calls after the upgrade... since i'm from Venezuela i can't use Sprint configuration...

so here's my question:

WHAT DO I HAVE TO BAKCUP FROM THE FILE "EPST" SO I CAN SET IT UP AFTER THE UPGRADE???

i'll be very much appreciated if any of the Senior members could help me here...

thanxs!!!

Nelson, there is a few month old utility that can extract an HTC ROM from the device directly to the SDcard. If you have the ROM (*.nbh) of your phone from your carrier then you could use a utility such as DogGuys Kitchen maker (ftp://ppcgeeks:ezupload@ftp.ppcgeeks.com/Titan/Users/DogGuy/DogGuy%20Kitchen%20Beta4.2%20Carriers.rar) to decompile the ROM. What you usually only need is contained in the ..OEM\OPERATORS directory.

If you look at how existing kitchens (http://wiki.xda-developers.com/index.php?pagename=TitanRecentHome) (and a FAQ on kitchens (http://wiki.xda-developers.com/index.php?pagename=Titan_RomKitchen)) are set-up, you'll see that each carrier tends to have its own operators OEM that the end-users selects when building their ROM. Following those templates you can create your own with the files specific to your carrier, and add that to an existing kitchen. Once done, then you can then build your own ROM. Though, with that done, of course the language files for your new OS ROM will be english rather than spanish.

The other possible option is to provide your carrier's OS ROM to the forum here and one of us may have the chance to decompile the necessary files and provide a set-up for you.

...sorry, I'm travelling right now and don't have the chance to go into greater detail or updated links.

whoa! I think u went way over his (and my) head with that one...

I don't think he's looking to cook his own rom, he just wants to install one....and wants to know what info he needs to document before so he can reinstall it properly afterwards..

wow thanks Keystone...

although Dillsnik is right... i read the FAQ on kitchens an it doesn´t sound complicated... but i´m not sure if i´m capable of doing this...

however i will be reading more about this kitchens and cooking my own rom because it sounds very interesting that i can put only the programs i want (wich by the way it´s exactly what i´m looking for), so i´ll be witing here soon asking more questions...

by the way, the main propuse of this thread is still open... and the quistion is in the first post:

WHAT DO I HAVE TO BAKCUP FROM THE FILE "EPST" SO I CAN SET IT UP AFTER THE UPGRADE???

thanks for the quick response!!!!

guys, installing the official Sprint rom before your rom of choice allows your carrier settings to be maintained, so there is no need to back up any of that information. at WORST, you'll have to get your a-key reset, which is a quick call to verizon(or your carrier?). i've only had to do this once, and i've flashed my phone probably 25 times.

install olipro 2.4
run Official Sprint RUU
at 'Tap Here to Set Up Your Device' install your rom of choice
run carrier cab (if its not in the kitchen)

if you try to make a call and receive a 'your phone cannot be authenticated' message, call tech support and dont let them tell you anything, just say 'i had to do a hard reset and now my phone cant authenticate i need a new a-key please.' theyll tell you that its not necessary and will try to do it automatically, then if they cant theyll give you a new a-key and tell you how to apply it.


EDIT: there is no way to view your a-key, which is why you are unable to back it up and why backing up EPST settings is pointless for you.

Well, I think Keystone is trying to give you a safeguard. You likely have a ROM that nobody else has a copy of here, and I'd suggest you dump a backup copy of it before you do anything to your device, just in case.

We cant give a definite answer to that because we do not know how your carrier operates.
In theory, the actual Sprint update should backup your programming and restore it for you. I do understand you wanting to have a backup plan, but in that case, I would suggest you record everything.
