When I try to dial ##000000 I get message that the call could not be completed as dialed.

Re: Uscc 6800 Gps, Custom Roms, Downgrading Guide
 

im just guessing here, but im betting that you put the sprint update on your phone and had the customizations run?

if thats the case you will have to downgrade your phone im going to start on that guide right now.

does, ##778 work?

Re: Uscc 6800 Gps, Custom Roms, Downgrading Guide
 

What exactly are you planning to downgrade? It has been stated multiple times in several threads that it is not safe and a downgrade of the radio should not be attempted at this point. Really not sure why you need to downgrade anything.

Re: Uscc 6800 Gps, Custom Roms, Downgrading Guide
 

No, it's http://ppckitchen.org/Downloads/BuildOS.msi

Also, reverting to pre 3.35 (No GPS) is a risky and therefore bad idea.

BTW, your Bold key is stuck.

Re: Uscc 6800 Gps, Custom Roms, Downgrading Guide
 

Im planning on downgrading the phone back to near stock, i say near stock because there is no offical USCC rom

Yes i read that in several threads about it not being safe after i got stuck in the locked bootloader, but i did find a way out of it and now have a system set that i can go back to the stock radio just fine and back up!

i have done it to 5 of these just fine and never once had to have the phone replaced

downgrading is a good idea for the following reasons,
#1 in case of warrenty work
#2 in case USCC releases an offical rom with GPS enabled
#3 in case you want to go back to the stock settings taking out GPS and getting all the OE files and programs back
#4 to start over incase you let the sprint customizations run that change everything on your phone even how you access certain features like the ##000000 and so on. its easier to go back than it is to fix a ton of differences

and im sure there are other reasons that im not thinking of.

Im making this guide to hopefully help some USCC people with this phone since it took me a few solid days to track down the information and try out different things as well as some of my own and get them to work right the first time! and over the course of this i had to downgrade my phone several times to start over!

any other questions? because i feel like your making a statment that it cant be done when it can be done for i have done it. and im sure others have as well, its just not all assembled into and easy to use blueprint (guide)

Re: Uscc 6800 Gps, Custom Roms, Downgrading Guide
 

lol yeah i see that its stuck i will edit that,

BTW try clicking the link to buldOS i posted, it does work :)

as for risky, i wouldnt say that it is any more risky than upgrading custom firmware :)

as with everything, its use at your own risk right?

but maybe, just maybe, if you have a working guide that if you follow it reverting back works, then maybe it will cut down on the people who think they "Bricked" there phone :) and, or help people who get stuck in a bootloader screen :)

Re: Uscc 6800 Gps, Custom Roms, Downgrading Guide
 

Well, the bricked mode is not just stuck in bootloader. However, I just wanted to make sure you were giving ample warning to people before they jumped into your guide once you put it up. If it works great, but I think people should also know that there are some serious consequences that may occur.
