[Upgrading, Modifying and Unlocking] lostsoul3471:
Limited success

Outstanding work so far.

My original problem was that GPS didn't work for me after the ID1 update period. My fiance has an Epix too, but GPS worked--and device.exe was locked at 60-70% usage after that. This rom fixed my issue, and GPS works again but it still has the high cpu usage after closing google maps or GPS Test.

Other observations after some testing this morning... GrandPrix 1.5.2 works, but oddly 3G data takes a bit of fiddling to work again after reboot. Tried the 1.9.2 version and that fixed it. (Could be that the setting needed to be reinitialized from the towers, and 1.9.2 took a couple extra steps.) There ARE a couple confusing parts. 1.9.2 will NOT complete until you reboot the Epix and finish the initial setup while tethered--so don't pull the plug until you're done.

I tried clearing the device.exe cpu use by turning the phone off in the wireless manager and that worked. However another test again with google maps came up with failure to get any sats after a few minutes. I rebooted the phone but still was coming up empty on the sats. I noticed that I wasn't connected on data and the location was cached in the google maps so no data connection was needed and/or made at the time it started. I started up IE, got to the home page, went back to google maps and reselected Use GPS and bingo it worked.

I'm leaning more to an issue with the radio/phone portion of the rom not necessarily on the pda part seeing that turning off the radio in connection manager had some effect with device.exe. Chalk this one up to AT&T's meddling perhaps?

This is really a great start and finally we have something that we can mess with. Now onto the other desperate need... anyone able to get the non-ID1 rom dumps to work yet?

Update:

Tried renaming Player's original part02.raw to a bin file. GrandPrix seemed to accept it but the download went to 100% and hung after that. The phone was then locked at the Samsung screen. I managed to reflash with alkoholic's pda.bin and it worked fine, so bricking was averted. :) Now I gotta ask, what tools did you use to get a working pda.bin file, Alkoholic? I managed to pick up some kitchen files from modaco for the omni which seem to work in getting the files dumped into directories, but it seems that it needs the OS.nb file which is not created during the dump and I'm even more sketchy in trying to use that to create a flashable image.

Update #2:

Found out that the OS.nb does get made using a kitchen for the Onnia(i900) as long as there isn't one already there. I'm torn between two avenues of doing this and neither seem entire all that easy or complete. There's the i780 kitchen and the Omnia kitchen(s) that are out there. The i780 is dense, not even sure exactly how to deal with it and it's pretty reliant on actual rom size for success it seams. The omnia kitchens split the files into something much more manageable but require you to alter a .rgu file which doesn't get dumped at all from the id1 update exe--or at least I haven't a clue where to find it. Hopefully someone is still paying attention to this thread and we can get some more info. And I have confirmed, that the stock ID1 update kills my GPS--tried again for S&Gs. With some level of initial delay it does work with Alkoholic's PDA file.
