Cellcom Rom Update needed!!!

[jstutting]

I would like to update my Cellcom HTC 6800, so I can turn on the GPS. Can this be done?

hello, today i went into cellcom and i talked to a tech guy and he said a guy came in with a htc 6800 updated to 6.1 on us celluar and it wasnt able to work now its stuck with us cellular unless he goes into us cellular and pays to get it unlocked. he said cellcom has nothing to do with the updates and that htc puts them out. i am in the process of contacting htc and hoping to get them to release a 6.1 rom for our phones. i will let you know what i find out. im guessing maybe if we get enough people to complain that they will work on putting the now one up on their website

I too, am with cellcom. I brought in a copy of a newer ROM to one of their tech folks and he is testing it on the 6800 as we speak. He is going to let me know if it works on one of their test phones. If it does I will let you know. It will have WM6.1, radio 3.42.50 (w/gps), etc.

Of course it can work. Provide a stock cellcom rom, or a rom dump, and we can make 6.1 w/ GPS work with cellcom.

Do we have to get the ROM from the carrier, or is there some way to "suck" it out of a phone?

There's a tutorial on xda-developers on how to use d2s to extract the images from your phone. You'll also (and most importantly) want to copy the ext_rom contents. You can use file explorer and ActiveSync to do that part. There is a 99% chance that the ext_rom contains all things related to your carrier.

I am also a Cellcom user. I have contacted my business rep and asked him to put me in touch with Tech Support so I can ask about ROM upgrades. I will post what I find out as soon as I know.

What I found out is you're not going to get any help from Cellcom. I will have to do some more reading in the forums and see if I can load a ROM upgrade from another carrier without "bricking" the phone

I do think it is possible doing the following steps (I am assuming you want to use DCD's ROM 3.2.6).

1) Dial #778 SEND on the phone and write down ALL EPST data
2) Flash the phone with nueSPL 2.47 to unlock the phone
3) Flash the radio to version 3.42.50
4) Flash the rom to DCD 3.2.6
5) Run DCD's carrier cab for ALLTEL's network (I know cellcom is not alltel)
6) Dial #778 SEND on the phone and re-enter all EPST data

I am close to doing thiis myself.
