Got the radio upgrade 3.3x and all works well with 2.x dcd rom, but upgrading to 3.0.1 has problems with phone calls. Both receiving or outgoing, the device resets 10 sec into the call. Also Voice Command 1.6 not working. sucks.
verizon xv6800
I'd be willing to bet millions you didn't follow directions when flashing.
Nope. Cooked a kitchen, tried the Verizon Rom....neither work with 3.0.1. works great with 2.x though.
Voice Command 1.6 now working OK as well under 2.3.2. I is happy. Still looking for good GPS software. I really liked Earthcomber, but doesn't work with this rom.
If you tried to flash the radio standalone, then the verizon cooked rom...you didn't follow directions.
The ONLY way to successfully upgrade to 3.0.x is by flashing the sprint update to upgrade the radio.
OK so I cry for help. Why the heck would I apply a Sprint update to a Verizon handset, granted both CDMA. I upgraded the radio at the same time as 2.2. The 2.2 DCD rom I'm using that WORKS WELL should be no different than the upgrade to 3.0.1. Unless I'm forgetting to stop customization with a soft reset.
You're not getting the point!!!
The only reason to flash sprint's official rom is so you can update the radio to its latest version. After this is done, it DOESN'T MATTER whatever rom you flash next, such as a Verizon rom. Use DCD's 3.0.1 rom it should be working. You would have known this if you read instructions. If you flashed the radio alone first, then your settings (ESN, MSID, etc) will be wiped. You will have to re-enter these either manually or call up Verizon to do it for you. This is probably why you can't make calls.
Exactly my point. I flashed the radio with the Oli 2.4 and updated the radio from stock verizon. Then flashed 2.3.2 and all is good with the new radio. So why doesn't it work with 3.0.1? I just found my way to the In and Out Burger via Odyssey Mobile locator.
Everyone keeps telling me that i didn't follow the destructions but they don't point to where they are.
Maybe wrong radio ver?
Crap. Mine says 3.24.00. I guess that's my problem. I'm an idiot.
Please point me to the proper radio D/L.
Thanks,
Sorry for asking what is probably a simple question, but I am having the same problems. I have SPL-2.40.Olipro atm, installed the verizon ROM upgrading to 3.0.1 from NexVision's Hybrid rom. My radio is upgraded to 3.25 or whatever it was supposed to do fine. On vibrate mode, when a phone call is incoming, I get stuck in an ever ending vibrating. I can text, and attempt to cal lsomeone but nothing can be heard and no one can hear me. I know i screwed up somehow- but what exact steps do I do to remedy this?
Thank you in advance
We have to do the Sprint radio update to 3.35 first, which is an upgrade from 3.27. Then go to ROM 3.0.1.
It's always interesting to me how people jump up to say "you're doing it wrong" but don't tell you how to do it right.
Here's how to do it right.
http://forum.ppcgeeks.com/showthread.php?t=17667
Gecko122, There is more to the Sprint file than just the radio... It includes the ROM as well.... My understanding is this:
1st - Run Olipro unlocker 2.4
2nd - Run Sprint Official upgrade , NO CUSTOMIZATIONS.
3rd - Load Custom ROM.....
That has worked for me.....
PS - the DCD 2.x.x series do NOT play well with the new radio, hence the 3.0.1 kitchen.... Driver differences....
do i have to flash back to a former version of dcd or anything? or can i start from a messed up 3.0.1?
hi Penn,
Well, exactly what have you done to your phone?
Bootloader version?
ROM version?
Radio Ver?
Then we can start from there and develope a plan to help ya.
Ignore that above - I re-read you original post....
Here's what you can do and correct me if I'm wrong Penn...
You have Oli-pro 2.4 bootloader loaded
You have DCD 3.0.1 ROM loaded
You have the 3.27 Radio loaded?
If the above is true, then we have options..... Let me know

No, I flashed new radio stand alone package by dcd first day from an olipro 1.20 then 3.0.0 rom then 2.40 bootloader, and then one day later 3.0.1 rom... I never use sprint upgrade at all, and I have no problem about my phone at all. There is not just one way

Correct me if I'm wrong, but weren't you the one with the extremely long, complicated post about how you were able to get everything working that way?
http://forum.xda-developers.com/showpost.php?p=2014972&postcount=326
Secondly, you may have been able to get everything working, but you're lucky. The chance of problems occurring by flashing this way is way too high in my opinion to even bother, not to mention others have had problems that absolutely cannot be fixed without reflashing back to stock and updating with the sprint update. That is why dcd removed the standalone radio from the Radio Rom thread.
Gecko, the reason why I did not "tell" you how to do it the right way is because dcd's thread has 94 pages of information on how to do it the right way. I've even posted several times on different pages in that thread with explicit instructions on how to. While I am always very eager to welcome newcomers to this community, I also strongly encourage them to read, research and educate themselves before touching their device. It doesn't mean I'm not a nice guy and don't like to help, because if you search my posts you will see that I help a lot around here. If you had simply taken 20 minutes and even skimmed dcd's thread, you would have found the answer yourself in no time.

Wow... I'm sorry, I had not been keeping up with the issues of others, so until you said that just now, I had no idea. You are right, I am really lucky, so thanks for bringing it to my attention.
No problem
Hi all,
So I installed the Official Sprint ROM issued this month and I have the following problems:
- Battery won't last more than one day
- Phone won't wake up from standby at certain times
- Phone slow after running some applications, including built-in apps like Word, Excel, or IE. Sometimes this result in the phone just simply hanging
In either situation above, except battery issues, a soft-reset is required.
I have tried the following:
- Do a hard reset, try without ANY applications
- Remove HTC_CM_Guardian.exe and SDDAEMON.exe
Anyone have the above three problems? with the new Sprint Official ROM?
I feel like going back to the old Sprint ROM. I have a separate BT GPS, so I don't care about A-GPS functionality as long as my phone is stable.
Why don't you cook a clean rom with the 3.0.1 kitchen and get rid of the sprint rom?
One question - did you let the customizations run after you installed the ROM?
If not, you need to hard reset let the customizations run, hard reset again and then you can bypass the sprint customization.
Otherwise......
......now that you have the new radio installed, I'd recommend trying one of the clean ROM's from either No2Chem (over at PPCGeeks) or DCD's 3.0.1 ROM.
DCD's has a "Touch" look to the skins and has over 24MB of RAM free on first boot.
All you'd need to do is run the 2.40 Olipro SPL unlocker and then flash DCD's 3.0.1 ROM.
Much more stable than the OEM.

I did on the 1st try, but something gone wrong, most troublesome is that the "Text Message" account now shown in Pocket Outlook. So I hard reset again and let the customizations run.

So you're saying that it's better to use Sprint's official Radio but use DCD's ROM?
What I gather from this forum and PPCGeeks is that people either use Sprint's Official Radio and ROM or just forego that and use kitchen's ROM completely, but not a combination of both as mentioned above.
[EDITED]
OK, so I got Olipro and DCD 3.01 Kitchen. Just so I am doing the right thing since I have ALREADY installed Sprint Official Rom with Radio v. 3.35.05, please let me know if this step is correct:
1) Connect to ActiveSync. Sync as usual
2) Run Olipro v. 2.40. This will open a Command Prompt. Let it do it's thing.
3) Once done, load DC 3.01 Kitchen ROM. No other Radio ROM needed.
4). Done.
Am I correct?
There is no radio with the kitchen. The sprint official radio release (3.35.04) is the official radio whether you use the sprint official update rom or a custom rom of your choosing. No other radio works with the newer roms except this radio. That is why if you choose to use a custom rom, you STILL have to flash the sprint update to get the radio, then you flash your custom rom on top of it (with no radio) to get your own rom on there.

I've cleaned that ROM (gutted to the base OS and functions) and have experienced none of those issues and none of those complaints are voiced in the thread using that kitchen.
I do not think that your problems are due to that specific base of Sprint ROM. Possibly some of the apps or simply a bad flash? Did you attempt to remove HTC Guardian or other components from within the active OS or did you extract and build your own ROM from the Sprint?
For severe battery problems there a couple of threads where a few people have experience excessive drains, but that's with the more recent DCD builds.

I already have Radio 3.35.04 when I installed Sprint Official ROM upgrade. That's why I want to confirm that I need to run Opilo 2.40 unlocker and then upgrade to DCD ROM on top of the current Sprint Official ROM.

You are correct, you can flash any custom ROM on top of Sprint's. DCD's is a good choice.

That is correct.
DCD's ROM doesn't include the Radio, and the new radio version is what unlocks the GPS and EVDO REV A features. The SPL unlocker is what allows you to load ROM's that aren't OEM on your device, and If you aren't familiar with how to build your own ROM using DCD's kitchen (it's pretty easy once you get started), then he has carrier specific ROM's already linked on his most recent release page. The links are just above the images.
http://forum.xda-developers.com/showthread.php?t=376150
Yeah just unlock with olipro 2.4, then you have a choice between dcd (which I personally use) or another clean rom like no2chem's.
same issue as stated in first post
Hey just want to say great site guys! There is no other website that can comes close to the knowledge available here. But in response to the who started this thread the official sprint rom is crap! Once phone goes into standby or "LOCK" 99% of the time "Soft Reset" is required. Ive "Soft Reset" my mogul no B.S. 100 times since I've flashed there ROM. Radio is a great improvement but honestly, they need to hire or pay NOCHEM or DCD for their talents because w/out their ROMS the MOGUL would've ended up on the side of the highway. I agree with the last post. Use the official radio, but don't run yourself through the wringer with the SPRINT ROM. You will rip your hair out!
meek420, again, I've had zero issues of lock-ups using a cleaned out version of the Sprint ROM.
I do not think such problems are endemic to that ROM.
Not to long ago i update to DCD's latest rom and radio. I never got the GPS to work for some reason though. I was wondering with the new verizon ROM out is there an easier way to get GPS. Could i flash to verizons new rom so that i have the radio and the rom and then flash back to dcds and still keep verizons radio. Becasue for some reason i just cant get the GPS to work with DCDs rom. Also i have noticed my phone lagging a TON latly and im not sure why. My contacts wont open somtimes and when i answere a call or dial out it rings but it doesnt show the phone on the screen untill about 45 seconds into the call. its been a pain coming out of sleep too and i dont think im running that much stuff on it. Any Suggestions?
(i also am getting a white spot on my screen, i have heard of this happening before. Is it a problem that gets worse and is there anything verizon can do to fix it?)
First off, if you load Verizon's latest update, you will not be able to use GPS as of yet unless you pay for VZNavigator.
If you have radio 3.42.50 and Rom 3.2.6, you should have no problem getting GPS to work.
1) Go to Settings... Phone... Services... and check the box next to 911 only. Then click ok. Exit... Soft-reset if you feel like it. Then go back and change it to Location On. Click ok... soft-reset.
2) Do the GPS - Fix found HERE
3) Download GPS Viewer... I have it attached. When you run it... hit scan.. this will find what port the GPS is on. Then select that port and hit Open Port. This will start streaming data. Go to GPS Status at the bottom... and you should see some locations popping up if you are in open air.
Let me know if you get this far.
that program you gave me doesnt work on windows mobile. thats a Computer version.

But at least the GPS works now after the rom update. Thank you!

tried reflashing rom
soft reset a million times
what else can i try?
Soon to flash...
I am probably going to finally flash a DCD rom for the first time today. It would be nice though if the images or software downloads on the GPS fix wiki were available. That's the only thing holding me back right now. GPS is the only reason to flash for me, so I want to make sure I can get it working.
GPS on VX8600 rules!
Well I finally gave in and flashed the newest DCD rom & radio. Wish I had done that a long time ago. I was having no luck with the GPS till I read this thread. The the GPS locks super fast and is VERY accurate in Google Maps. This site rules.
While I am technical, I new new to everything phone related.
I have Radio 3.37.75 and ROM 3.57.605.1
Do I need to go back and install a different Radio and Rom version to run the GPS fix and enable GPS?
Thanks!

You need to install a custom rom ( to replace the 3.57.605.1 VZ Rom) to enable the GPS chip on the phone. That rom has the GPS disabled. DCD 3.2.6 rom is what i'm using and it runs pretty sweet.
As far as the Radio rom goes, i dont think you have to update it. There some debates going on in the forums about wheither the new VZ radio rom is better or worse then the current radio rom that was ripped from attel. Some say its better, some say its really the same (same file size) and some say its way worse.
So in summary, to run the GPS Fix, atleast install DCD's custrom rom first. (Note: Do not let Custimization run, the rom is based off a latest sprint rom, so letting it run as a verizon users messes things up. soft reset after initial bootup after a flash and pull the battery if it starts to do it. also remember to hard reset after flashing any rom)
PS. If you flash the radio rom, you will have to do *228 again to reprogram your number back into the phone.

If you flash DCD 3.2.6 do let customization run, he rips out the carrier specific stuff out of the rom, so it can actually hurt not to run customization on his rom. Only stop customization run if you are flashing an original carrier specific rom that is not your current carrier, i.e. if you flash a sprint original rom on a VZ phone, etc.
While based on a Sprint rom, he has taken the time to make it safe to run on any carriers phone.
DCD's customization runs UC and I think a few other house cleaning items, so it's important for it to run.

I have spent hours trying to fix this GPS thing. I followed this tutorial (http://wiki.xda-developers.com/index.php?pagename=VerizonAGPSFix) to the letter. Everything on the phone works fine except this gps. What am I doing wrong???
-I upgraded to the VZW MR1
-Then switched to DCD3.2.5 (Radio 3.42.4)
-Then followed that above link
Nothing seems to work.
If you aren't going to use MR1, then don't upgrade to it. Downgrade back to official Verizon WinMo 6.0 stock rom, then unlock, flash to a newer radio and then flash DCD 3.2.6 and your GPS will work.
The Valhala cab thing only works if you are running MR1, if not, then you don't want to install MR1 or it will disable your GPS.
BTC
I have read so many of these xda and ppcgeek threads now my brain is spagetti. I have also come across MANY conflicting threads discussing the whole GPS issue - on a wide range of ROMS, radios etc. Is there a tutorial on how to do this?
The only reason I switched to DCD's ROM was I was hoping to get ICS working. Alls I want is a WM 6.1 ROM that will give me unrestricted use of my GPS, and ICS to work properly.
Go to Settings > System > Device Information...
What PRI (Not PRL) version are you running?

Dude you are a genius!!!! Your quick instructions have finally ended a long hunt in searching for this solution. After I did what you told me, I have both blazing fast GPS connectivity, and fully working ICS. I want to mention a few things in case anyone else runs into the issue I did.
First, after I successfully downgraded, and then reinstalled DCD’s 3.2.6 (radio 3.42.50 & PRI 1.35_002), I did NOT follow the instructions to enable AGPS. I dont know if this is being overlooked somehow on all these forums, but after I installed my carrier cab, with DCD’s 3.2.6 ROM, everything worked as is. There was no need to install anything else. Also keep in mind, that I did exactly as BillThyCat instructed, and that was flashing directly from the stock WinMo 6.0 (no MR1 update) to DCD’s 3.2.6.
If I read your last response correctly, it sounds like you did not do the aGPS fix afterwards. It's not a requirement, but it will get you 15-20 second GPS locks almost every time you try. It's well worth it.
Glad you got everything else working tho. Your issue is a pretty common problem. With most carriers you want to load their latest stock rom then upgrade from, however Verizon being the bastages that they are, lock the GPS down. There have been a few work arounds found, named the Valhala cab, however if you are going to run a custom rom anyways, why even mess with all that. Just use a custom rom and work.
BTC
Yes, I did not do the AGPS fix posted on that wiki site. Im not sure I understand why doing that AGPS fix would give me 15-20 second GPS locks, when I have like 8-10 second GPS locks now. Perhaps the magic is just in the latest radio. Either way, I'm happy with the way it all worked out.
When I first programmed my phone I would get syncs instantly one day and 10 minutes or more the next. If you are consistantly getting them in 8-10 seconds don't mes with anything, just keep in mind if that nice feature goes away that aGPS is available in the future.

So I bought a phone that was branded qwest. It is the Mogul Titan 6800 I'm not sure of the point for all the different names but it looks like the Sprint or Telus Phone (circle instead of square navigation button) Anyways I paid someone to flash it to cricket. It ended up having a Verizon splash screen and a radio version of 3.37. The person who flashed it said GPS would not work with this particular flash, and if I wanted it to work he would have to do it on his own time because the guy he worked for had a certain ROM they liked and he could not flash a GPS ROM on his boss's time.
So I flashed to Gamedics ROM and then flashed To) V3 ROM. CI could not get GPS to work with either. I then upgraded the radio to 3.42.50. Still GPS does not work. I added GPS toggle and quick GPS but they did not help either.
I read somewhere about the Verizon MR1 update and how GPS would not work with it. Is there anyway that the original flash that I got was this MR1 and for some reason it has stuch through my other flashes preventing GPS from working? Is there anything I can do to make GPS work on this phone? I also have something QPST if that helps.
Thanks in advance.
My thoughts, and it's only my thoughts, this was probably flashed to MR1, which disables GPS, when your cricket dealer flashed it, he didn't flash it back to an older Verizon stock rom first to undo the GPS lock, you might try flashing an older Verizon stock rom, let it run customizations, then take it back to the dealer and ask him to flash it again, let them do whatever rom they want, but when you get it back home and go back to GAMedics, or whoevers rom, GPS should work.
You might call the cricket guy first, make sure they won't charge you to flash it again, and if not, then do what I suggested.
Or at least ask the tech guy who did the flash for you and see if maybe their rom uses the same verizon locks.

I now have the capability to flash it myself. Could you direct me to an approbriate ROM to undo the lock?Then I can flash it back to my current ROM.
Thanks for the reply.
The only rom that I know of is the original stock Verizon rom, it's windows mobile 6.0, it will do carrier customization, which I believe it has to do in order to unlock the GPS.
Hopefully your Cricket rom restores the Cricket customizations.

Same problem here
Almost the exact same problem, but I have a Verizon branded refurbished (insurance) phone.
It had the latest Verizon ROM (6.1 - 3.37 radio) on it when I got it.
Am I able to put the Verizon 6.0 ROM on it?
I thought that would downgrade to a non-GPS radio , and that could brick the phone?
Here is my two cents... I Have xv6800 on VZW and Verizon users always had a hard time with GPS until GC figured out a GPS setting you had to apply with QPST. Its in the "HTC Titan Links/Information - PLEASE READ BEFORE POSTING ANYTHING" section sticky in this forum. Since then I use Baf GPS toggle today screen plugin to toggle GPS on or off. It always locks in 2 or 3 seconds. It looks like you said you are on cricket and I don't know if there are similar settings to apply with QPST. This all assumes you haven't flashed the MR1 Verizon upgrade, you are on a 3.something radio and are using a GPS enabled ROM (most if not all in this forum are). I never messed around with the MR1 upgrade so i don't know about it. Flashing back to the original verizon wm6.0 ROM in my case has involved re-locking the phone, and flashing the original ROM (which includes the original Verizon radio), then un-locking again, flashing the latest radio, then a wm6.1 ROM.
If you do some searching on this forum you can find answers to most of your questions.
Thanks. I have searched, but it was unclear whether I should downgrade to a non-GPS rom/radio (I've read that it's dangerous).
The guide I read here was actually pre-GPS rom release.
I went ahead and did downgrade, and then upgraded radio and installed a custom rom.
Now I get super fast locks.
Thanks again.
