UPGRADING A USCC 6800 TO USE GPS

I can't find the "Titan_No2Chem_5060_WM6.1" selections. What did I do wrong?????
Thanks

I have a PPC6800 that needs to go back to US Cellular for repair. Is it possible to get this back to a "stock" system now that I have upgraded the GPS radio?

Re-read the first page of this thread, or at least this this one post

basically u can install non-GPS SPL then flash non-GPS radio and ROM, easiest way i've found to do it was install SPL via RUU and then Radio/ROM from an SD Card. Before you start make sure u can flash ROMs normally from your SD card. And of course if you brick it dont blame me. All flashing is done at your own risk. Any radio downgrade from runs the risk of download mode.

The man who sold me my mogul was really into this stuff and he sent me a disk with lots of things on it. One of them was the stock rom folder that included:
usctitanextrom.bin
usctitanos.bin
usctitanxip1.bin
usctitanxip2.bin

I tride to unbind the bin files with magic iso and usctitanextrom.bin was viable but none of the others. I put Qwest upgrade on and let it customize my us cell phone SAYS CELLSOUTH AS CARRIER. I should have read a little more before I lept off the edge. I don't know if any of this helps, but let me know.

The very first thing you should do is download QPST and use it to read the programming off of your phone.

To get your MSL/SPC do a google search for BAFMSL, make sure you have .net 3.5 installed on your phone and it will give you your MSL/SPC. I believe this works on all carriers, where GetSPC only works on Sprint and a few other carriers. If you can't get this to work, there is a registry hack that will create a temp file that shows your SPC as well. It's just more complicated.

You will need this to read your phone's programming with QPST and save the information to a file. (You will need this later, do not skip this step).

Next, I recommend using the SPL2.47 bootloader as it can be done from the phone and doesn't require activesync (to me it's easier, faster, and safer). And also recommended as it supposedly makes the phone faster and more stable.

Once this is put on to the phone, then use any radio newer than 3.27.x, I personally use the latest from DCD. Once this is done, then download DCD 3.1.2 rom (this will be replaced later, just need it to run QPST again).

I do all of my flashing from the bootloader screen, as it's faster and easier to get to. You need a 2gb or smaller MicroSD card and SPL2.47 will format it for you to the correct format.

Once 3.1.2 is on the phone, rerun QPST and write your programming back to the phone (You did save it after reading it, right)

Reboot the phone.

It will come up and say Cell South (This is fine, dial *22 and let it do a PRL update, it will also fix your carrier banner.

Once you are this far, you can then flash any rom you want, DCD, No2Chem, Scrosslers, Etc.

If you guys want to use this as the original post, I will go in and put in more details, etc with links. Just don't want to do all this if it's just going to be overlooked.
