You can use any of them except the VERIZON Rom upgrade. The VZW ROM upgrade locks down the GPS while the others (Telus, Alltell, Sprint) open the GPS all the way up.

-= WARNING: DO not let the Customizations run for a differnet carrier. If you do you will tie your phone down to that carrier. =-

If you want to go Stock then I would recommend the Alltell ROM. has the latest radio.

If you want to go Cooked then I recommend NueROM3 Pre3. You have to Donate to get a copy of it but its nice. It allows you to disable camera to gain extra memory.

Eitherway, good luck.

hi i also have cellcom and i was wondering if you ended up upgrading to the 6.1 rom and which provider you used on the htc website.

[fxdfireman]

no, i have not updated my rom yet, i am looking at cooked rom but haven`t took the plung yet. if you do let me know how it works for you.

well i recently tried to install the altell from and when its started to install it said it wasnt compatiable with my device and then it just went back to all my old settings and no data was lost. i also went to my cellcom business sales rep and she said they most likey wouldnt be putting out the new 6.1 rom.

sorry for the spelling errors. this makes more sense now

I too am with Cellcom and have been very frustrated with this phone. Have you guys tried DCD's ROM? You realize you have to upgrade the bootloader and radio before you update the ROM don't you?

If you are interested, PM me and I would be happy to tell you what I have learned. I have spent over 10 hours reading this stuff and am fairly technically savvy. I have not done the upgrade yet only because I am waiting for a response from Cellcom on them putting out a 6.1 upgrade with GPS enabled.

I may upgrade anyway depending on if I can't stand it any longer (and that is pretty close). Incidentally, their coverage has been GREAT in our area.

well if you could explain this too me i would appriciate it cuz i dont understand what i have to do to upgrade to 6.1. also cellcom will not be coming out with the 6.1 rom.

Based on what I learned so far, I will give you the steps below, but first, I highly recommend you read the WIKI at the following 2 links...

SUGGESTED READING
1) http://wiki.xda-developers.com/index.php?pagename=HTC_Titan
2) http://wiki.xda-developers.com/index.php?pagename=TitanRecentHome

STEPS TO UPGRADE
1) Read the 2 WIKI's above
2) Dial ##778 on your phone and hit SEND. This will start a utility called EPST. Write down ALL of the EPST information including all parameters on ALL the VIEW INFO softkey submenus. Later when you need to edit the EPST info, our MSL unlock code is 000000 (six zeros). Make sure after entering the MSL that you hit the OK softkey and NOT the enter key on the keyboard as that does not work (it just beeps at you).
3) Replace the stock bootloader (probably version 1.07 LOCKED if you phone is like mine) with a new UNLOCKED bootloader. I recommend nue2.47-SPL Installation Package found HERE (http://www.nuerom.com/BlogEngine/page/nueSPLnueSPL-ReLocker-for-the-HTC-Titan.aspx) (there is a PDF with instructions inside). To find out what bootloader you have, hold down the POWER button and the CAMERA button and hit RESET (while holding the other 2 buttons down. The phone will boot to the "rainbow" screen and show you the SPL version. Just hit reset to reboot the phone.
4) Install a new radio ROM. I recommend version 3.42.50 found HERE (http://dcd1182.n715dp.com/titan/radios/) (this is one of the newest radios and supports the built in GPS).
5) Install a new ROM. I recommend dcd3.2.6 found HERE (http://dcd1182.n715dp.com/titan/roms/)

The reason I made the suggestions above are based on everything I read, dcd's ROM is VERY efficient. You will have much more memory left over, the phone will be much faster and more stable, etc. It will be Windows Mobile 6.1 with a working GPS.

Read thru the WIKI's for detailed instructions on how to complete the steps. There will be ways to do this via USB cable or SD card (make sure you use less than a 2GB card). I recommend doing ALL the flashing via the SD card as supposedly that does not effect your A-Key (Authentication Key). Once done, you re-enter all of your EPST data and supposedly you should be up and working.

The only step I feel a little gray on (will make more sense after reading the WIKI's and learning about the work dcd has done) is dcd recommends installing a "carrier cab" when you are done. Since Cellcom is a tier 2 provider, I don't believe there is a "carrier cab" for us, but I believe manually re-entering all the EPST data takes the place of this. If it still won't connect, you can supposedly dial *228 once the phone is working to have the carrier automatically setup your network connection.

Since you are with Cellcom, you are probably located near me geographically. I would be willing to help if you are interested as I obviously want to do this too. I believe you said you have 100 phones? I have 1. Therefore I would love a little more assurance that I am doing everything correctly before I jump into this.

If you are interested in working together, send me a private message and we'll work something out.

Good Luck and please let me know if this works for you (I believe it should).

If you more experienced phone flashers out there see any errors in my post (or want to add assurnace that I understand steps correctly) please feel free to voice an opionion.

P.S. I had this post 99% typed out and acidentally shutdown Firefox! Argh! I typed it again cuz I really want to help you and verify this works with Cellcom before I jump in too.

Also, if you decide to use dcd's ROM and we get this working, I suggest we send him a paypal donation. I will be for sure. From what it sound like, he puts a ton of time into fixing this phone and helping people out.

Thanks for all that information. I am hoping to try this soon once I read a little more in depth

[onioneater36]

That would be fine. If any Cellcom'mers out there successfully update their phones, please let me know. If I can get confirmation that it can work, it may persuade me to make the plunge.

hello, i was just wondering if u went ahead and upgraded. because 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.

[onioneater36]

Why doesn't he just put no2chem's nueSPL247 on his HTC6800 and unlock it himself?

[cmaricque]

idk i didnt talk to him myself thats just what the tech person said to me cuz he was suggesting i should upgrade till htc comes out with the update. i think if we get enough people to complain to htc they would work on releasing it.

[cmaricque]

offically have WM 6.5 on my moguls. Runs Great. if you still need help let me know. i have done alot of reading before i went ahead with all of these updates.
