OK, so I have tried a couple of the codes at the link in the first post, but when I change it I go into a 1x connection. Anyone know why?

EDIT: OK, so I have horrible Verizon

service at my house, but awesome Alltel. I found a PRL that took me from -103 to -68!! BUT. I am on 1X still. Anyone know how I can get 3G with it?
[Droid Incredible Android Development] x1208x:
Ok so the file you posted, is this still based on region?

IE I am in California Near SF. Would this PRL file apply to me or just in your area? Does the PRL refer to specific towers in specific regions?
[Droid Incredible Android Development] tcberg2010:
Just restored back to froyo/sense and the prl stuck.
[Droid Incredible Android Development] michaelnhf:
This is a legit verizon prl, you should not see any roaming charges. if they said something just tell them that they pushed you the prl from the local store because your signal was bad, or better yet call and ask them to push you the prl. if you ask for the hybrid one they should send it.
[Droid Incredible Android Development] michaelnhf:
have u ever been charged roaming data charges doing this?
[Droid Incredible Android Development] mellojosh:
The PRL I attatched should work in any region of the U.S.

I personally have not received anything odd on my bill for doing this. I have a Nationwide 1400min Family Share plan. Verizon states that there should be no roaming charges for Nationwide plans except when international.
[Droid Incredible Android Development] HyBReDM:
Allright I have the same plan. I'll give it a shot I suppose. The siginal in my neighborhood is awful but everywhere outside of it it's great. (Gainesville, VA)
[Droid Incredible Android Development] thatdudebutch:
So this would be used instead of the posted Alltel/VZW prl file?
[Droid Incredible Android Development] mellojosh:
In most areas where Verizon is available, a hybrid PRL with Altell/VZW will still default to VZW. In Atlanta, an Alltel/VZW PRL is useless since the PRL will still pick Verizon and the merger pretty much combined those towers anyway. In more rural south Georgia, on the other hand, an Alltel hybrid PRL can improve reception as Alltels network is a bit more widespread for that area. I would just use the one that provides the better signal, which for me is Sprint not Alltel. Also reference my first post about SIDs and switching between Home Only and Automatic to make any of these hybrid PRLs work to your advantage.
[Droid Incredible Android Development] br125:
did anyone else that manually updated the 65144 prl find that they could not make outgoing calls? I tried that and the other hybrid prl from the first post and neither worked... back on the 51926 prl and all is well
[Droid Incredible Android Development] x1208x:
that prl file didn't work for me. lost 3G service.

went to check it with

*#*#4636#*#*

Showed: CDMA Auto PRL

BTW you can toggle for CDMA only/ CDMA Auto PRL / EvDo Only / etc.

man wish it worked. so just fyi guys i'm in california near san francisco on verizon. if anyone else tries this or any other prls that are successfully giving a stronger single, please post!
[Droid Incredible Android Development] bwthor20:
Nope, been with Verizon for years.
[Droid Incredible Android Development] HyBReDM:
Same gate you're in, but in Northern VA.
[Droid Incredible Android Development] TNS201:
I put this PRL on my phone yesterday. Received a few calls and made a few, sounded like it degraded my sound quality, but did increase my signal.
[Droid Incredible Android Development] rcicu:
Just installed will let you know how it goes. Thanks!
[Droid Incredible Android Development] obededom:
I lost 3g and now have the roaming indicator on my status bar, how do I roll back?

both *228 and *22899 take me to Alltel's automated system, which will not let me either activate or update the prl
[Droid Incredible Android Development] michaelnhf:
Go to the link in my OP and download the 51926m Prl then use the same method to update as you normally would the whole *228 thing.
[Droid Incredible Android Development] obededom:
edit: problem fixed
[Droid Incredible Android Development] obededom:
my prl before attempting the hybrid mods was 51920 if that matters

EDIT: problem fixed after reinstall of PRL
[Droid Incredible Android Development] mellojosh:
Hey yall, I had a recent issue with my device and did a reset and used the file from my post earlier in this topic. I realized by using this file I originally uploaded the wrong file. I went ahead and updated it for anyone wanting to switch between Sprint and Verizon. The original one I posted was an alltel/vzw one. Sorry for the mistake. Go to post #35

http://xdaforums.com/showpost.php?p=7163241&postcount=35

I am working on removing the roaming triangle when using VZW towers with a Sprint SID (read the post from the link above if you need clarification on SID/PRL relationships) So while using Sprints network you shouldnt see a roam indicator, even though it is roaming, and see a roaming icon with VZW enabled, which really isn't roaming. Also, *228 is a good way to test your hybrid network setup. With the right Sprint SID and the hybrid PRL in my post, when switching to Home Only and dialing *228 the caller should receive an error message from a male announcer, indicating the phone is on Sprints network. When selecting either Auto. A or Auto. B, the caller should get the VZW programing menu with the female announcer. You can choose to continue from here if you wish to restore VZW only prl.

Added some screen shots to show differences for my home area. These readings are taken from the same location. Operator name does show as unkown on both networks. Havent found a way to display the banner.
[Droid Incredible Android Development] johnnybags:
Couldn't this method also be used to get out of your contract without an early termination fee? I used to work for Verizon many years ago and there was a clause in the contract stating that if you spent more than 50% of your minutes roaming they could terminate your contract. I'm not sure if that clause is still there, but I would guess that it is. It wasn't a hard rule, you could exceed the limit a couple times without consequence, however those who consistently roamed for the majority of their minutes over 2-3 consecutive months would eventually get a termination notice. By using this PRL and changing the SID, you are basically forcing this condition to happen.

This could be a bad or good thing, depending on your objectives. :)
[Droid Incredible Android Development] mellojosh:
I'm not 100% sure. I know there are many cases where roaming becomes a problem with certain plans, especially if the cell user see's the charges on their bill and has to get credits every month, but I recently requested a trouble ticket for my area to try and improve reception and technical support was not able to determine if I was roaming in any recent months. I have been using this since May.
[Droid Incredible Android Development] drellisdee:
Here is a newer hybrid (uses alltel towers as precedance over native vzw ones). FYI if the hybrid works better for you call tech support and request they push you a hybrid prl and everytime you *228 ota you will get a hybrid. I currently use this one on my Imagio and I get about 20 dbm better on 1x and hdr/evdo/3g than the native vzw one. I marked this one as evdo so no one will try to use this on a 1x only phone fyi.

I wouldn't recommend using the sprint sid/prl trick stick with the legit alltel hybrid. You are basically creating your own roaming agreement with sprint. If caught your roaming fees will be quite abit and if terminated due to violation of TOS it will be with ETF charged.
[Droid Incredible Android Development] drellisdee:
try *22800 or *22801
[Droid Incredible Android Development] thejosher:
how do the EVDO speeds compare on your phone in areas that have solid verizon and sprint coverage?
[Droid Incredible Android Development] mellojosh:
I went ahead and did some real world tests in 3 different areas around town. One around the mall area, where reception is good on every carrier, one at home where my reception is only good with Sprint and one at work, where there is no Sprint, but a VZW tower on top of the building with indoor repeaters for VZW. I used the speedtest.net application from the market to measure my speeds and made sure no other application were running while testing each time and disabled syncing services to try and measure under the same conditions.

Scenario 1 Mall-Great VZW and Sprint service reception:

VZW Average- 1.6MBPS down 910kbps up

Sprint Average- 1.4MBPS down 860kbps up

Scenario 2 Home-Poor VZW reception and good Sprint reception

VZW average- 490kbps down 290kbps up

Sprint Average- 1.2MBPS down 840kbps up

Scenario 3 Work- Good VZW reception and poor Sprint reception

VZW Average- 1.5MBPS down 890kbps up

Sprint Average- 350kbps down 210kbps up
[Droid Incredible Android Development] trunksta:
It's much different. Hybrid prls are able to get signal from other carriers (alltel in particular) such as towers that aren't yet switched over to VZW.
[Droid Incredible Android Development] abe01:
I've been using this SPRINT/VZW PRL mentioned in this thread because I have a great signal with verizon while at work but I don't at home. Sprint is good at home though!! THANKS!!!!
[Droid Incredible Android Development] thatdudebutch:
I have yet to try the sprint prl.. is it also a alltell prl??
[Droid Incredible Android Development] trickykid27:
Here's something totally off topic but intriguing... If we can't do simultaneous voice and data on CDMA then how does the PRL file update itself over the air when we're on a phone call to *228. I never understood how that worked.
[Droid Incredible Android Development] mellojosh:
Hmmm...not 100% on this, but I believe that the PRL file is edited from the OTA system, not actually transfering data. If you have ever noticed, text messages can be sent and received while in calls, but picture/video messages can not. Picture/Videos require web/data access to send receive as CDMA uses seperate channels for Voice/Data. With this theory, the OTA system can send text edits to the PRL file while holding on a call, I.E *228
[Droid Incredible Android Development] spartan141:
wheres the file?
[Droid Incredible Android Development] thejosher:
You rock - thanks! I'm really surprised Sprint allows full-speed EVDO roaming on their network. I wonder if Sprint phones have EVDO roaming on Verizon? I have no native Sprint coverage where I live currently but Verizon and Sprint both have pretty solid coverage where I'll be moving next month. Can't wait to test who has the best data speeds :)
[Droid Incredible Android Development] johnsquared:
EPST? Can't select .zip

Anyone have an update on this? I'm getting the same result.

***EDIT*** Nevermind. I figured it out. Just had to select "all file types".
[Droid Incredible Android Development] hexto:
How do you check your db reading? I remember seeing it before but can't find it

Update: Nevermind...I found it
[Droid Incredible Android Development] theguitarguy58:
Can someone upload that prl file here? And confirm this working ?
[Droid Incredible Android Development] past_pluto:
I called vzw tech support b/c my phone started cutting out words from every sentence and they put me on a hybrid prl and made it where I get it with *228. I didn't even ask for it so maybe if you just call them up they will give it to you.
[Droid Incredible Android Development] ouikikazz:
i did the prl update and it works fine my prl shows the correct version in software abouts....but when i go to ##775 now the ONLY option i have listed is update prl.........ideas?
[Droid Incredible Android Development] ncwildcat:
##778 for full control...##775 fir prl only
[Droid Incredible Android Development] ouikikazz:
Doh!
[Droid Incredible Android Development] Bobb_o:
Hey mellojosh are you in Atlanta? Before I go ahead and mess around with this (I'm running a non-sense 2.2 rom right now) I want to determine if it's worth my time to get a lot better reception.
[Droid Incredible Android Development] ncwildcat:
I have been playing with this as well. We have sprint repeaters where I work, and I get horrible reception inside the building. Do I need to use the SID for my area (Raleigh) for sprint in order to use the verizon/sprint hybrid? I ask because I tried it and had the constant roaming triangle
[Droid Incredible Android Development] ncwildcat:
I played around with this again today for some time - signal was always much worse with sprint sid/sprint verizon prl. Maybe our repeaters use another prl or sid or something ,but I definately was not getting signal off of them. I have been using wifi at work, and getting -95 to -105db signal on my wireless connection with verizon prl and sid. Tried Alltel sid and the hybrid prl, but didn't help (I am a former Alltel customer). Oh well, back to watching for updated PRL's I guess
[Droid Incredible Android Development] Xylite:
Possible to use GSM tower / repeater?

I work in a basement all day and am just outside reach of Verizon reception. I tried the hybrid PRL today, but didn't have any luck picking up a better signal.

My company uses AT&T repeaters inside the building. Just to verify, there's no way to pick up this signal since it's not CDMA, correct? I understand Verizon, Sprint, and Alltel are the major CDMA users, which is probably why their towers can be used interchangeably.
[Droid Incredible Android Development] Raptor567:
I've been running the Altell/Vzw hybrid PRL for a few weeks now. I haven't noticed in huge difference in reception in my area, but it does make me feel better heh :D.
[Droid Incredible Android Development] Dmtalon:
With the Hybrid Sprint/Vzw prl what's the difference between

Automatic A and B?
[Droid Incredible Android Development] chillmeow:
Hi,

How do I back up the current PRL?

I did update *228 option 2 to update my PRL, but the PRL version did not change which stays at 51920; however I did notice the signal level raised.

Where can I get the 51926 or 51926m? and What is the difference between the two?

I would like to try the current PRL before I test the Sprint/VWZ Hybrid PRL.

Thanks!
[Droid Incredible Android Development] Whitepaint:
I actually got the VZW/Sprint Hybrid PRL posted somewhere back in the is thread to work. I get 1-2 bars maximum at my home on VZW But everywhere else around my house full bars. But I do get full bars on Sprint PCS service at my home. This PRL made the difference of about -20dbm-30dbm... Couple of issues,

1. The Roaming signal icon, (shows as roaming anytime your on Verizon towers)

2. My Phone wont do 3g while on Sprint Towers... (No big, I have Wifi at Home)

3.My battery Drains about twice the speed using this PRL. Don't know why. But it does.

Its easily reversed by putting the phone in Automatic Mode (to join Verizon towers) and dialing *228. This will Change the PRL back to Regular, But the HOME:SID/NID change sticks. So if you put your phone in Home Only mode you may lose signal. Don't know.
[Droid Incredible Android Development] Dmtalon:
I tried two different PRL's from this thread. Neither of them seemed to change my signal or give me a roaming indicator.

my PRL number was 30036 on the first one and 40047(I believe) using the second one. I used *228 to get back to 51920.
[Droid Incredible Android Development] Whitepaint:
30036 is the VZW/Sprint Hybrid PRL. You have to change your SID to the Sprint SID for your area + use that PRL and then set your phone to HOME ONLY under Mobile network settings. This will force your phone to roam on Sprint towers (although your phone will show NOT roaming while on sprint towers using this PRL)
[Droid Incredible Android Development] manatti:
Hey guys the difference ia as follows

Home only - VZW cell towers

Auto a- only used in certain areas

Auto- VZW and roaming cell towers. You should be set on this or just auto if you don't ha e the a or b option. I work for VZW. Hope this helps
[Droid Incredible Android Development] KGBxxx:
Sooo what your saying is nothing helps if you have crappy coverage at home.
[Droid Incredible Android Development] DeaconBoogie:
Going to the 65144 seemed to work for me... Ever since I did *228 and updated a few weeks ago (to 65156), my phone had consistently been dropping to 1x at my office.

Going to 65144 seems to give me a steady -68dbm signal and four full bars, 3G speeds are much better as well.

UPDATE: As soon as I posted this, BAM back to 1x... LOL
[Droid Incredible Android Development] jasek78:
none of these codes are working on the ruby rom :( ##778 or any of them i have tried
[Droid Incredible Android Development] smtom:
65144.prl - will/can someone please post here?

I REALLY would like to try this, and I've learned a ton from reading this thread - many thanks to those who educated me extensively on this topic!

Don't know why, but for unknown reasons, I am completely unable to d/l the 65144.prl file from ppgeeks' site - tried a couple different names & such and successfully registered/activated both, STILL cannot d/l file - can anyone please pin it in this thread?

Thanks in advance to those more wise than I.....

[Droid Incredible Android Development] ncwildcat:
That is because EPST is not built into AOSP roms - load a Sense rom, setup your PRL and options, and reload your rom of choice. EPST settings will stick when you do the changes.

Tried this. So far no difference ~ still -89 for me before and after.
[Droid Incredible Android Development] crump13:
I tried this twice. I went through the process step by step and didn't receive any errors. My phone reboots as the instructions states after selecting Menu and commit modification and when my phone comes turns back on my PRL hasn't changed. I'm an former Alltel customer still on my Alltel plan and my signal sucks at work. I was hoping this would help. My current PRL is 40067 and I live in Tampa FL. I have the SkyRaider 2.5.2 w/sense ROM, my radio is the 2.15.00.09.01, and I have S-off.

Any thoughts as to way this doesn't update my PRL when I go through the process?
[Droid Incredible Android Development] seanmcd72:
Are you unzipping the file that you downloaded? As long as you have a phone that has EPST installed, this should not give you any issues.
[Droid Incredible Android Development] crump13:
The file extension is .prl not a zip file so all I did was download it from the url a few posts above.

When I'm in ##778 and go to prl then select update prl, the file is found and I select it and hit ok, then menu and commit and then it robots. I check my prl and it is the same one I have had, it never updates to the new one.

Send from my Droid Incredible.
[Droid Incredible Android Development] adamant13247:
If you downloaded the file above and as long as you have a senseless rom that has EPST installed, it should update fine. If it didn't it's probably because your area doesn't have 65144 supported. For example, when I downloaded it I was at 59xxx and I updated and I have 65024 (based off of my roaming zone). It's all according to what roaming zone you are in! :)
[Droid Incredible Android Development] mellojosh:
quicker way to get working easily

Hey yall, sorry hadn't checked this thread out in a while. I found it was becoming very difficult to keep trying to update all the PRL files I was trying to create, so I found a way to use the stock PRL without modifications. For this method, I use an application called Roam Control. It's not a free app, but saves a ton of headaches and time, well worth the current price of $3.99. This method should work for any carrier with a roaming partner, in my case I am Verizon and want to roam on Sprint. In my case, Verizon chooses not to have Sprint as a roaming partner in areas where Verizon should be present. However, Sprint uses Verizon much more frequently, so their PRL's have both tower information. All you have to do is find a copy of the latest Sprint PRL (included for convenience :) ) and flash it by dialing ##778 and choosing PRL, then select the PRL from the list and save it. After a reboot, you will now have a Sprint PRL and be connected to a Sprint tower, I check it by trying *228. If you get an error message by a male announcer, then your phone is on Sprint. Using Roam Control, you can then choose Roam Only. The signal should cut out, then return with a triangle. The phone is now on Verizon. The triangle shows because the PRL is made by Sprint, which would be roaming on a Sprint phone. Hope this helps.
[Droid Incredible Android Development] androidsteve:
Every time I update to the hybrid prl it throws me into 1x and no 3g. Is this common, and its there a fix???? Thank you

For EPST woes.....

Hey guys...I've just been messing around with some of the PRL stuff on different ROMs and thought I would post some things about what I have found that might be useful to some people. Applying PRLs is different based on what kind of ROM your phone is running. I have found there are pretty much 3 ROM types. Those that run stock android (like the nexus one has) stock sense (whats on the phone out of the box) and modified sense ROMs (like the Desire HD rom). For the stock, the programming is going to be similar to programming a Motorola Droid. ##7764726 usually will spark the popup for the SPC password, which is 000000 by default. The stock sense programing allows for much better control of PRLs. It is accessed by ##778 and then the SPC password, noted above. Modified Sense seems to be the most cumbersome, usually do to the missing EPST files. While checking around some other posts, I found an EPST apk for the EVO. Apply the apk through Astro and finish. Important EVO programming codes are now available. Working known codes are

##775# - EPST/PRL - PRL Settings

##786# - EPST - Status Menu

##3282# - EPST - Data Programming Menu (User Name, Advanced, Restore, Enable HFA, DSA Server, MMSC URL)

##2539# - EPST/A-Key - Data A key menu

##7738# - EPST/P_Rev - Protocol Revision

##8626337# - EPST/Vocoder - Unsure

##4772579# - Reset the GPS

##72786# - changes DSA back to Factory

##889# - enables TTY

Currently I use the Desire ROM and use this method to flash the Sprint PRL to my phone when I am home.

Hope this helps anyone who might be looking for any of this.
[Droid Incredible Android Development] luniz7:
Interesting
[Droid Incredible Android Development] codybear:
FYI: Alltel has always been ran off of Verizon towers only since the day the company first started.

Also, some parts of Alltel's "coverage area" were sold off to other companies. Long story short, the reason for this being is if they did not sell those parts, Congress would not have allowed them to merge as it would have made Verizon a "monopoly."

======================

But anyways, back on topic...I tried this and it popped up a search box, I put in "65144.prl" in the search box, clicked okay and everything else was the same. My phone on the otherhand hung up and wouldn't update...just said to wait while updating. (Yes, I waited for about 30 minutes and backed out of it and restarted). I checked after rebooting just out of curiosity and it was still on PRL 40066 that I have had since a week after having my phone. I just did the *228 update and it updated to 40068. lol. So this sucks for me.
