I saw something here about this from azclown and really want to know if it is true.
After flashing nueSPL is it possible to downgrade to other bootloaders?
I tried to run unlocker (Olipro 1.20) and it wouldn't connect right. Do I need to use relocker then load 1.20 then load stock rom. I am testing this out for another phone right now and am a little curious why this would be created so that no other bootloaders could be reloaded.
What I am realizing is that this bootloader is not such a good idea for Verizon users, being that they will not be able to revert to the stock rom (as Verizon has not released a GPS Rom yet).
Am I right here?

um, DO NOT attempt to DOWNGRADE your SPL unless you want a permanent brick.
reasoning:
ALL ATTEMPTS whatsoever to downgrade the radio to a pre-GPS radio have F-A-I-L-E-D. They have all resulted in BROKEN BRICKED IRREPARABLE devices.
1.xx SPLS are not (at least that i'm aware of, compatible with GPS radios)
therefore, you cannot downgrade your radio to 1.xx.
You can downgrade to olipro-2.40, but thats pretty much it. Unless your device is SuperCID, i would NOT ADVISE locking your device, because you will only be able to download updates signed by VZW, and as we all know - there are none.
If warranty is a concern,... it would be better to turn in a complete brick than a partial brick. flash a modified VZW OS Only with proper OEMDRIVERS, then run my relocker and lock the SPL down, then warranty it. /... I wouldn't suggest this for anything else, because in case of a bad OS flash, you'd be pretty screwed...
Thanks for chiming in on this no2chem, there's a lot of good information in that post!

now, by that do you mean they werere were bricked by downgrading the radio with nueSPL previously (or currently) loaded on the device, or downgrading the radio on a device that never had nueSPL loaded on it?
the only reason i ask this is because ive done several radio downgrades from olipro 2.4 to 1.2 to the stock radio/ROMs for refurbishment and ive never had a problem. i dont use the stock SPL because theres no tech around here smart enough to check it.

No2chem.. I think I am an exception or my XV6800 must be special because I actually messed up my phone because i wanted the new Radio 3.42.02 but couldn't get my Phone to Flash From SD.. So I had to flash a sprint 3.56 ROM to get the Radio and then flashed Verizon kitchen before Sprint customization started.. but for some weird reason.. Sprint customization still ran after i flash the Verizon ROM.. My EPST Settings were all Sprint.. lols..
These are the steps I took to bring it back..
1. Ran Titan_Relocker to relock SPL from version 2.40 Olipro
2. Flashed Stock Verizon ROM and let Verizon Customization run
3. Unlock using NueSPL2.47 letting it format my SD card to enable Flashing from SD [Thank GOD you added this feature]
4. Placed the new Radio 3.42.30 onto my SD card and enter Bootloader and Flashed it [Thanks to You]
5. then flashed my Verizon kitchen.. All with no problem..
I've discussed this method with some of the guys over at PPCKitchen.org and they were concerned about me bricking my phone.. but I said oh what the heck.. my phone is already messed up..
every one was supprised that it worked.. lol.. I must be one of the lucky few..

weird. what were you running before step 1?
the problem seems to manifest itself when you take a GPS radio, and flash a 2.xx RADIO onto it. When you flashed the verizon stock rom, are you sure you had the 2.xx radio on it?
the reason everyone was concerned about your phone though, was because there were several bricks produced by downgrading radios - ask ImCokeMan, he'll tell you..

I didn't quite understand your question..
"When you flashed the verizon stock rom, are you sure you had the 2.xx radio on it?"
When I ran Titan_Relocker.. it installed version 1.06..
Before the Sprint radio upgrade I had...
Hard SPL2.40 Olipro
Radio 3.39.10
No2chem wm6.1 5067 Kitchen
I have also went from a GPS radio to the stock verizon radio/rom a few times because of accidentally letting sprint customizations run.
i am not 100% sure if i had the stock radio on my phone. however it worked with stock verizon rom and phone/ data/ text all worked in stock verizon rom/radio.... so i assume it was the correct radio since it worked with the stock rom...?
EDIT: i do believe i had verizon 1.3 radio on my phone after flashing back from a GPS radio
also i remember reading somewhere that if you do flash back to a stock radio/ rom that it might say stock radio but it will still have components of the gps radio's... i think i read it at ppcgeeks

i also have downgraded radio from 3.xx to 1.xx without any problems.
I flashed back to non gps as well. I was having bad experiences with dcd's 2.x so I went to his 1.7. No issues flashing at all.
I have also downgraded to 2 different phones from GPS radios to NON-GPS radios.... Verizons stock radio is 1.30, not a 2.x radio, so that may be the issue for some other folks on different carriers.... It may be an incompatibility with 2.x radios and GPS radios.... I have a folder on my desktop that has all the files necessary AND the instructions clearly written out on how to downgrade..... It has saved my butt 2 times now....

Ya I used to switch from gps to nongps all the time back when the original leaked radio was the only one out... I also converted my last phone (sent in for broken button) back to complete stock vzw (locked and all) as well....
I haven't tried doing any downgrading after installing nueSPL though... are you indicating this is a probelm after flashing nueSPL? Your post has me a 'lil scared now but I'll wait for followups before I attempt anything.. no plans to go back to nongps anyways, though... the new radios seem to have the bugs worked out.

Only No2chem knows for sure, but after reading his post again I think he's saying you can downgrade to Ollipro 2.4, if thats the case then one should be able to downgrade back to stock as well....
I think no2 is onto something here. I am on VZW also and have gone back to stock from a 3.xx gps radio --> stock 1.30 radio.
I have a feeling that for once we may be glad that verizon never does any updates - they still use 1.30 radio - and that may be the common thread in all our (vzw) success at going back to non gps.
I'd say that I was onto this before him.... He just knows how to verify it...

Speaking of the man himself ^^^^ .. I would note that you had all the data, I just thought it was odd that anyone who tried to go back to a 2.X radio would brick it, while us verizon folks would go back to 1.X and have no issues....

hi, i just got the XV6800 from verizon today because my Moto Q9m died after only 7 months. so they gave me this for it. now after reading the forum and many other sites and tutorials. i am ready to flash my phone. is this the easiest "[Tutorial] Verizon xv6800 Custom ROM Flashing" to follow? i read it and it didn't seem that bad. just wanted to know and make sure if the names of the files he speaks of are the most recent one's. and i take it i should back up my factory setting file off the phone before i attempt to do this. a few of my friends at work has this phone and i liked the fact they have it doing somethings the iphone does. like you can scroll through contacts by just sliding your finger and all. i would like to do this stuff as well. is that all then included in the flash or must i install other apps.
Phone has
Software Version: 2.09.605.8 (ROM version)
Firmware Version: 1.30.60 (radio version)
please help, really appreciate it
thanks
His guide is pretty good. Everything is up to date except for the SPL. I would recommend using the latest bootloader put out by No2Chem - version 2.47, but that's my only change from his guide. It installs via an SD card only, whereas his guide uses the computer to get Olipro's 2.4. You should be able to find a guide to using SD cards to flash as well as links to 2.47 throughout this forum and ppcgeeks.
Or you can certainly follow his guide as written and you'll be just fine.

Keep in mind that using No2chems SPL you cannot go back to stock Verizon radio and ROM..... So if your phone breaks, you have to bring it in as is and chance they don't notice the difference.....
ok on the fact that once you go new flash you can't go back to factory. so before i do this i should back up my contacts. since the phone is new i don't have anything else on it. is there anything else i should back up either? so after its flashed then how do i get the programs on to scroll by just sliding? is that stuff that can be put on with out flashing this. but from what i read on here flash makes the phone run much better anyway

You can flash the old bootloader back on the phone after upgrading to 2.47 though then go back to the original ROM and radio, you just cant flash provider ROM from 2.47 just like you cannot from 2.40.
Am I missing something about what you are saying?
so i can flash to newer rom and be able to go back.. now i'm confused
if you i install themes must it be a new roM

I'm pretty sure he's simply saying: if you use No2Chem's 2.47, you can't directly flash back to Verizon's stock firmware, but if you flash back to the old bootloader (factory bootloader), you can.
and LilSnoop40, as far as I know, all of those files are the most up-to-date that I could find. I may update the guide because I am noticing (from other people's experience) that after the 3.42.02 firmware (which I flashed to, not 3.42.30), that you need to use a Low-density MicroSD (not MicroSDHC) card to flash on the new radios.
If you need help with any of this in more detail, feel free to contact me.

serfs - As I understand it, once you flash to No2chems SPL, you cannot go back to a non GPS rom. I asked this in his thread and it was confirmed. Now, they didn't say whether you could flash Olli Pro and then use his re-locker and then flash the stock ROM.... Look at this post....

I had to turn my Titan in for a replacement. Knowing about relocking breaking the usb port, I figured I'd do it anyway and just flash via the SD card. Well to my amazement I was able to relock and flash the OEM Radio and Software without and problems. Once it booted up Activesync connected and charge light came on.
Just figured I'd share since there is so much fear about relocking.
Went from 3.56 based ROM and 3.42.30 Radio back to OEM.

I have never heard that story, nor have I ever had any problems going back and forth between GPS and non GPS radio.
While testing the new Sprint PRI way back when 3.49 came out (I'm on Verizon), and now testing the new Verizon update, I've had to go back to stock more times than I can count and have never ran into any issues.
May I ask where you found these rumors?
EDIT: Ahhh ppcgeeks...yeah don't really frequent those forums much. Not sure why n2c would say something like that because like I said, I've probably gone back and forth between GPS/Stock at least 15-20 times with no problems at all.
Read the first post in the link I gave you. Then you can do a search on downgrading issues to find more reports.
I know it can be done because I've done it on 2 different Titans now. I made the thread to help prove that it can be done so other arent so scared by the rumors as you call it.

In my encounters with going back and forth, this is what I've come up with (for Verizon users):
If using SPL 2.47, steps to relock are as follows:
- Install Olipro 2.40 via USB
- Install SPL 1.06 using Titan Relocker via USB
- Flash stock rom/radio
(DO NOT EVER USE nueSPL Relocker!!!)
To get back to SPL 2.47 from stock, all you need to do is run nueSPL Unlocker and use the microsd card to go from SPL 1.06 right to SPL 2.47, then flash a 3.x.x rom/radio. Going FROM SPL 1.06 TO SPL 2.47, SPL 2.40 is not needed.
If using SPL 2.40, steps to relock are as follows:
- Install SPL 1.06 using Titan Relocker via USB
- Flash stock rom/radio
To get back to SPL 2.40 from stock, all you need to do is run Olipro 2.40 via USB, then flash a 3.x.x rom/radio.
If using SPL 1.20, steps to relock are as follows:
- Install SPL 1.06 using Titan Relocker via USB
- Flash stock rom/radio
To get back to SPL 1.20 from stock, all you need to do is run TitanUnlocker via USB, then flash a 1.x.x rom/radio.
Now all there is left to do is link this to ppcgeeks and be done with the rumor. Thank you for your input....

I vote to have this added to the return to stock wiki. GC will you post?
How about USCC?
Brings me back to my previous question, GC (Previous Thread); How can I back-up the current ("Stock" for USCC) OS ROM and RADIO on my new Titan? It was discussed that it [dumping current ROM and Radio and then using dump to re-flash] couldn't be done. I wanted to do a ROM dump before flashing to DCD's so that I could revert to it if needed; also, so that I could re-flash to "stock" on my old unit before sending it back to USCC... however, I don't how to accomplish this, if at all possible to do so!
If anyone can guide me through this, I could upload the USCC "Stock" (for lack of a better word, since USCC has no actual "Stock" Roms) ROM and RADIO and make it available to other unfortunate USCC customers. I agree w/Serfboreds, and also vote to have this thread added to the "Return to Stock" Wiki.
Thanks, Guys!!

I think the issue lies with Sprint customers..... I personally have reflashed to stock at least 15-20 times.... from a GPS ROM and back.....
That is a very nice summary of steps for re-locking from various spl's and definately needs to be entered into the !iki.... If GC doesn't have time I'll do it when I get done here at the dentist.... booooooo....
I think the real issue was going from bootloader nueSPL 2.47 to a stock GPS rom caused problems. But because verizon customers dont have a stock gps rom to flash back to we go to a non-gps (1.XX) radio which does not cause the problem.
No2chem originally made the advice not to go back to a stock assuming stock included 2.XX or 3.XX radios. Once he was alerted to the fact that going back to stock 1.XX (i.e with verizon) did not cause a problem he modified his warning advice.
Once again, the warning is only valid for bootloader nueSPL 2.47
GC, does going from nueSPL 2.47 to olipro SPL 2.40 prior to relocking negate problems for everyone? I ask that question because I have refrained from moveing to 2.47 for fear of problems in the future. As far as I can see the benefits of 2.47 are marginal at best. But if I have a sure fire escape mechanism I might upgrade my bootloader at some stage

Thanks dude. And I agree with Serfboreds that you should add this advice to your wiki. Very easy to understand and maps out all (most) of the possible relock escape routes.
Once again gc you are a font of wisdom.
ugh.... i can't keep up with all the misinformation anymore. If it works for you verizon users in your personal experience though good for you. I know for a fact it can cause problems. I'm starting to narrow it down to the original 3.35 leaked rom with GPS radio from sprint, but have no firm proof it's that narrow scope yet . Still have myself a brick from the GPS to pre-gps and I didn't use nueSPL Relocker thats for sure =P
For more info on the problem and others that experienced this "rumor" first hand go to ppcgeeks and search for "download mode"
So as the title states the offical ROM for verizon broke my gps for all the roms i have tried. Now this gets me wondering if the Official rom simply has some QPST tweaks to make it only work with VZ nav. But its quite annoying that i figured i would try the rom only to figure out that the GPS lockdown is NOT rom based. I was wondering if anyone knew how to fix this. Thanks!
I Second that..
I tried flashing the titan 20273 kithcen.. then 20270.. then no2chem 5067 as well.. tomtom will just say poor gps signal.. and just stays like that for hours..
can some one please figure out a way to fix this... VERIZON.. You Bastard!
Try dcd's baked rom. I flashed it and GPS started immediately, after vzw update.
From the info GC14 posted a while back it would seem that the new radio is to blame...at least that was my understanding. Flash one of the other radios and see if the GPS function is restored.

This is one of the reasons it wasnt leaked, there will undoubtedly be scores of people less familiar with flashing who "brick" or "break" their devices.
It is easy to get GPS back working after new VZW, but we need to get a fix the same method as Sprint; aGPS.
And, its not just QPST, there is a .dll in the way that requires vznav.
Already tried other radios.. im currently on 3.42.30.. still no gps.. FUUUGGGG.. Verizon.. You Bastard!

You need to go back to the stock bootloader (using Titan Relocker), then flash the original stock Verizon Rom letting the stock customizations run. This will roll you back to PRI 1.35. Once that's done, flash SPL 2.40/2.47 again followed by your custom rom/radio of choosing. You WILL have to reapply the Titan GPS Fix with QPST if you were using it prior to flashing the update.
Your GPS should be back to how it was after that.

PRI = Primary Rate Interface, correct? What does that have to do with GPS? Is the new ROM some how using the PRI for the aGPS or something? If this doesnt make senses its because I dont know what I am talking about and would love to learn the more technical side of this.
Thanks for any info GC.
No PRI = Preferred Radio Instructions. The radio has everything to do with gps.

Oh, Ok. Got it. Thanks!
As far as restoring GPS follow GC's instructions earlier. I did and I am good again.
O.K. flashing my XV6800 with the official rom recently released was the first time I flashed anything. I am now serously considering reflashing to the new DCD rom to get the GPS functional. I realize I need to flash the radio as well, but other than that I'm flying blind. I have read through the wiki and think I can do this following a decent guide.
My question is, can I follow any of the guides out there, or do I need to take special steps now that I've flashed the new VZW rom? I've found a each flashing guides that I think I can follow, but would appreciate links for noob-oriented flashing guides.
You will have to take the PRI back 1.37_002 using the RadioRefresh.cab. The "official" update changed it to not allow 3rd party GPS.
http://forum.xda-developers.com/showthread.php?t=421275
Is there any confirmation that this actually works for someone who has gone from the original Verizon xv6800 firmware to the MR1 firmware, without having done any other flashing that might have written values into the radio EEPROM/flash that we don't have visibility into? [I suspect this latter point is probably the source of the confusion of various tricks working for some people and not others.]
There seems to be quite a bit of confusion as to what restores the PRI and what doesn't, and whether the PRI is actually the thing that definitively controls the enablement or disablement of the standard GPS API, or whether simply something else that happens along with the PRI update might be responsible.

if you want to be a guinea pig, you can try spl 2.47 and a custom ROM. see if GPS works. im looking for the threads on this.
you can always revert to the MR1 firmware if you wish.
I've considered it, but I don't think that I want to be taking the first big step there as I don't have any extra phone aside from the xv6800, and hosing that would be a PITA.
Presently focusing on seeing if I can convince LBSDriver to return useful data with the MR1 firmware, though I'd be interested if anyone can corrobate a known working procedure for a phone that has had no custom firmwares/radios aside from the original Verizon release -> Verizon MR1 release.
To flash or not
Am I correct in assuming that if I do decide to flash, but don't like the results that I can just run the MR1 update again to get back to stock? I have read where others have said that they flash the MR1 without re-locking.

DCD I am running 2.47 SPL on my verizon 6800. What do you want me to be the guinea pig on? I am not great at this stuff, but willing to help if I can.

As DCD said, going back to PRI 1.35 was not necessary for me. I still have the NEW PRI 2.03_002 on my XV6800 and I can use GPS just as I did before.... Now here's what I did....
I went from DCD 3.12 --> NEW VZW upgrade. GPS didn't work so I flashed back to "stock-non-GPS rom) Then flashed the 2.47 No2chem SPL, then flashed radio 3.42.30 using SD card, and then finally DCD 3.15. No I didn't actually check then, but I did 3 days ago, and I have PRI 2.03_002 on my phone but GPS has been working just fine..... So take that for whats it's worth, but there have been a few others who have also had success using GPS even with the new GPS on the phone....

but your aGPS is still locked to VZNav i assume. any real benefit that you see of being on the new PRI?
WOW - GPS on the VZW 6800 that works!!!
This took about 2 hours to get done but right now it seems to be worth every minute.
I've tried all of the fixes, some kinda silly - felt like I was being told to sling a cat over my head in the front yard.
BUT THIS ONE GETS LOCKS AS FAST AS MY SPRINT TOUCH!!!!!
I am using 3.2.6 and the 3.42.4 radio after following the above (I have kept the new PRI).
I thought I was getting something wrong. Then I tried the GPS 5 miles apart, rebooted, tried again - same results 5 or 6 sat lock in less than 30 seconds.
I'll continue to monitor in the next couple of days and report any change. But darn - WOW!!
Finally flashed
Well I finally flashed to the DCD rom and radio today. I flashed radio 3.42.50 and DCD 3.2.6. I finally decided to flash for the GPS, but I guess that isn't gonna happen since I had previously flash the VZW MR1 update to a stock phone. I went through the titan gps fix and everything went as the wiki said it should. But I have no working gps. I assume this is because of the 2.03_002 PRI without ever having flashed before.
I've read quite a few gps threads and I think all my settings are ok, but I can't seem to get it working. Any ideas?
BENLANE, just to I understand... you upgraded to the new official VZW ROM, and then changed to DCD 3.2.6 and radio 3.40? What bootloader are you using?
Are you sure this was not a placebo?
As sure as I can be

I don't know how else to test but I've tried to make it fail - soft resets, moved around 5 miles etc. I tried it again a few minutes ago - almost instant using Live Search.
I follow all of the directions included in the post #8. Then I used DCDs 3.2.6 and the 3.42.4 radio.
Regedit
Before I follow the instruction in post #8 and re-flash, are there any registy entries that I should check that could be disabling my gps right now?
Don't think registry edits do it

Like I said above, I've done virtually everything short of slinging a cat above my head in the front yard. I've tried 'em all. The registry edits, the 3 additional files, use of the GPS toggle, etc etc. It always lead me to believe that whatever was needed was on Verizon's end. With the PRIs, I believe we have it.
Based on past experiences, this may not work tomorrow but for today - COOL RUNNINGS.
So simple answer, I don't think a registry edit will get it. I believe it is a combination of the PRIs, the unlocker, the radio and most of all the terrific ROM from DCD. He's the real deal.

I loaded the spl 2.47 and flashed the 3.42.40 radio, can I just reflash the dcd 3.2.6 (which I'm currenly using) or should I flash a differnet OS version?
Sorry for all the noob questions, I just really want the GPS working, and I'm lazy to boot.
I'm really starting to wonder if I'm gonna be able to get it working. I think my situation is different than most on this forum. I went from stock to the MR1 update, to the DCD rom and radio. I don't think I've read any posts where anyone took that path and got GPS working.

I havent read all the posts in this thread but it sounds like you locked out GPS functionality when going from the MR1 update to a custom rom. When you upgraded with the MR1 update, you installed a new version of the PRI. It appears that this version locks out GPS functionality, even with a custom rom.
You might want to check out gc's thread from hell for more info on this and how to go about getting back the old PRI. Its time consuming but works. There are supposedly other methods but not many have had success with them.
You've misunderstood

I did all of the above intentional to have the new pri on my phone.
Update on locks - still getting them fast, but they have slowed to an occasional lock in about 2.5 minutes.
GPS is working
Well my GPS works great now, all thanks to this thread.
Bad link animez...
Okay, I've looked around the forums and tried a number of things. I started out wondering if I should install the new update. Got to looking around and decided to just install a custom rom. Was a little weary because of my experience with the xv6700. Anyway. Ran SPL Unlocker to install 2.40 Oilpro. Installed the Radio 3.27.00 and dcd 2.1.0....did a *228 and then my phone would not pick up service. Tried a few things but since I was in a hurry just ran the vzw update and it fixed it. Later I come back and decided to try an do this right. So I run the RadioRefurbish. It worked and rolled me back to 1.35_002. Still no GPS. I've tried everything including this:
http://wiki.xda-developers.com/index.php?pagename=VerizonAGPSFix
Still no change. I do not get a fix. I mean GPS Viewer can see the GPS but I never get anything from it. I have a bluetooth GPS and can get a fix inside on a cold start in 5 min max. I left this thing for hours. Indoor, in the car, etc... nothing. I'm at a loss. I am currently running SPL 2.40 Oilpro. Radio 3.42.02 and dcd 3.2.3. With PRI 1.35_002. I had read of success with the new vzw PRI and NueSpl 2.47. Tried to install 2.47. Gives me checks on all of the prequisites and then when I continue it goes into the bootloader and displays spl 2.07 I have to then soft reset and if I go back to the bootloader it's still 2.40. I am at a loss and would really like to get this working. Any suggestion from any of you oober smart people out there would be great or just someone that might know what else to try.
P.S. Thought about trying to flash back to the original rom but had read where that can easily brick my phone. So that's about the only thing I haven't tried.
oober? lol...
First, what guide were you using that had you using such an outdated bootloader, radio, and rom?!
Secondly, am I to understand that you ran the new MR1, WinMo 6.1 from Verizon, with the new PRI? If so, I would try GC14's fix, he has a thread on it, to roll you back to the old PRI.
Thirdly, definetly use NueSPL 2.47 for flashing. Grab the newest radio, 3.42.50. Flash that. Grab the newest dcd, 3.2.6, flash that. Then install the Verizon Carrier Cab. Then do a *228 option 1. Call verizon *611 if need be, to re authenticate the phone if you can't make calls or use data.
Fourthly, go into the Phone control panel, and Get Settings on the Location option. Make sure location is enabled.
Fifth, do the new aGPS fix that was posted by gc14.
Lastly, get a program like Google Maps that is known to be highly compatible with GPS. Set it's GPS options to COM4, 4800 baud. And enable Use GPS. After initializing GPS for about 15 seconds, you should see a very fast lock of about 5-20 seconds or so with the new aGPS fix.

Why are you using such an old rom?
PRI rollback really required?
Is the PRI roll back really required? I went from the MR1 update to DCD 3.2.6 and radio 3.42.40 and got GPS working without rolling back the PRI. My process was;
1. Titan GPS Fix (almost the same as AGPS fix wiki)
2. PRI from hell (only did first step, flashing back to stock)
3. Fix from PPCGeeks (My GPS did not work at all till I did this)
4. Verizon xv6800 aGPS Fix
As far as the PPCGeeks fix goes, I'm now using the PDE IP & port# in the SUPL_AGPS keys in the registry, long with GPSMODE=4. Everything seems to be working great. Maybe I'm just a fluke.
The stock rom I flashed back to when I started the PRI from hell fix was VzW_titan_20273_a2.rar (I think this is the right one, only one I found on my laptop that seems big enough). Now that I think about it I did do the second step on the PRI from hell, I changed my bootloader to 2.40, and reloaded DCD 3.2.6.
i believe that guide would be from PhoneNews as its still one of the top results for "GPS on HTC Titan." Of course no one reads that there is an updated guide, but even that isn't that recent (around release time of 3.35). plus, they give ZERO credit to DCD or anyone on any forums, and took if upon themselves to host all the downloads, and not link to the forums where these originated.
3.42.50 has issues with gps on some phone for some reason. flash with the sprint radio and it will work with out issue.

Well, not saying it's a better fix, just the one that got mine working. But thanks to the xda-dev forums it went from a searchlight to a laser beam.
I've got a solution for GPS on the MR1 release for the xv6800. I should hopefully have a full release soon, but there is hope if you're stuck and unable to get anything except (possibly) VZ Navigator working due to the firmware being placed into locked down GPS mode.

I was able to roll back to PRI 1.35_002 using Radiorefurbish. I would love to install nuespl 2.47, but how. I downloaded it, ran it. It formated my card and ran. Reboots into the bootloader with a spl of 2.07 and just stays there. When I soft reset, reboots as normal. If I enter the Bootloader after that it's still 2.40. I've tried it from a few different Roms thinking that maybe there was an issue. BTW, How bad (dangerous) is it to flash back to original stock. It's about the only thing I haven't tried. I had read that going back to a non GPS rom is a bad idea.

The reason you are stuck in 2.07 could be because of your sd card. try a different card. SanDisk works really well with them.

I had the same problem trying to use nuespl 2.47. I just kept getting stuck at that screen. soft resetting and trying again. I gave up for a few hours... and came back to it and with absolutely no rhyme or reason, it just decided to work one time... I was also using the SD card method with a 2gig micro. I hope it just decides to work for you.

Just use the gc14 guide to roll back to the old PRI as stated and be done with it...
3.42.50 radio works fine with GPS, doubly fine with the aGPS hack.

I should have room to upload it on my comcast account. I'll PM you a link when it's done. Standard warning that flashing back to stock has bricked phones (from what I've read). Didn't happen to me, just saying.
Flashing back to MR1 should work. From what I have been told, the problem occurs if you flash to a pre-GPS version after having upgraded to a GPS-enabled version.

ah yes... MR1 would be no problem, but I believe pri from hell fix first step is referring to the pre-MR1 stock (if I'm not mistaken). so I see where animez is coming with the warning. At that step, all you can do is hope for the best I suppose...
Ive flashed back to the ut of the box" stock rom form the SD card several times with no issues at all.
now as far the radio i don go below 3.xx
I still cant get my GPS to work after i updated my PRI, even before i updated it was very hit or miss, I would get 10 sec locks or none at all for days
