quick question before I do this hack, do I need to call sprint and ask them to reset my phone's profile with the server? I ask because whenever I force roam my phone the verizon voice always comes up and says I cannot complete this call.

I just don't want to do this hack and be stuck since I can't ever roam normally anyways.
[EVO 4G Android Development] frozndevl:
No, you are fine to not call sprint. However, if you are unable to make calls, call sprint to have them reset your profile server side. I had to do that this mourning. Also, you can always just choose to update your prl from the updates screen to get back to a sprint prl.
[EVO 4G Android Development] KB112:
Just want to check...but often times when roaming you need to be sure your dialing the area code and number. If I quickly call my wife (7 digits) it won't go through, if I use my contact list etc with area code it works fine.

QFT! At my office I get a weak azz Sprint signal. I'm lucky if I'm hitting 250-400 kb sometimes. I switch to VZW and I'm clocking 1200-1500kb.

[EVO 4G Android Development] nickespi:
Not completely, depends on the PRL and which cell tower you are linked to, for example. I purchased RC, but when i am roaming in Los Angeles area, I am connecting to an other carrier "NOT" VZW, how i verify this is the *228. This has allowed me to roll back the PRL so that RC works correctly!!..I just need this for Voice calls in my area..So i personally don't try to abuse this exploit, i would be damned if im paying an arm and a leg for vzw..just my .2 c

Area plays a roll in how this will work out for some - i had to experiment and find out which worked best 4 me..
[EVO 4G Android Development] twebb32:
I just used the 0001 PRL because on Sprint i've been getting 40 kbps down 200 kbps up. When I switched to 0001 i get 1 Mbps down and up. But when I make a call, I don't get the 2 beep roaming sound and mobile signal widget says i'm on sprint.

Is this what other people are getting? No 2 beeps? What does your mobile signal widget say?
[EVO 4G Android Development] Product F(RED):
The PRL itself dictates what is roaming and what isn't. Being that you're using a Verizon PRL, your phone thinks Verizon is the Home network and Sprint is roaming.
[EVO 4G Android Development] RegnierD:
I must say, even though this has nothing to do with my phone, as I'm on Verizon, this is seriously impressive and super cool.

I wish we had this many smarty-pants over in DInc Land. :P

App to make me go on Sprint when not at Work.

I only use the hack because at work I have the worst service with phone calls and data. Is it possible to use some app like Roam Control ( want to make sure it works before I buy it) to force me to use Sprint when I'm not at work. I'm on Myn's Warm Z so ill hate to go back to Warm 5 and then back to Warm Z everday before and after work.
[EVO 4G Android Development] KB112:
I have been running Warm Z as my daily. Why do you need to switch roms for the prl? I just use epst 2.1 and switch between prls.

Epst 2.1 ...How do you access it? I can't even get to epst on Warm Z by dialing any of the ##numb#

[EVO 4G Android Development] 00mred00:
previously the epst menu did not work on gsm ports....what did you do to get it working or are you running a nighlty of warm z (not the posted version..in which epst 2.1 did not work)
[EVO 4G Android Development] bsmoove386:
I'm running the nightly from 3/23 all i did was put in ##775# and it worked the prl update prompted and asked for my password and i was able to update my prl. I was surprised it worked i thought i had tried before. I'm not sure if myn ever added into the rom. I had did the hack before I flashed Warm Z.
[EVO 4G Android Development] KB112:
I did this on Warm Z RLS1. I just loaded the older version of epst using Root Explorer. Works like a charm.

Anyone else get an error this morning something about your PCS account is invalid while on the VZW PRL? I've been running 31337 for over a month, at first I thought Sprint pulled the plug but after switching back to 60677 I have service again. Haven't tried any of the other VZW PRLs yet, just curious if it's just me...

EDIT:

Just tried the other PRL's, still a no go. Official error message below.

I tried to do it this morning too,and it's real laggy and keeps closing on me
[EVO 4G Android Development] ThaDSman:
I get the same error every 5 seconds...I might have to switch prl
[EVO 4G Android Development] Pjack107:
That error indicates ur nai and or nai password has become corrupt you need to update your profile while actually on the Sprint Network, also even though the phone thinks your home network is verizon, your Sprint acct on average only allows for 300MB roaming in a given bill cycle, hope this info helps someone. Peace
[EVO 4G Android Development] GatoEnFuego:
I tried the profile update on the sprint PRL then back to VZW and still no luck. Thanks for the tip though.
[EVO 4G Android Development] frozndevl:
What it sounds like is that your profile on the server side has become corrupted. Just put a call into sprint tech support, tell them that you are getting a message saying your phone can't be authenticated (or something long that nature, it doesn't need to be specific). Tell them you have updated both your profile and the PRL and it doesn't help. They should ask you to turn off your phone, they will re-provision your profile on the server side, and you should be back in business.

This has happened to me several times, most recently last week sometime. Quick and easy fix.
[EVO 4G Android Development] GatoEnFuego:
How do I explain that my phone works fine on the official Sprint PRL but not when I'm using the VZW PRL? :D Or does that not matter?
[EVO 4G Android Development] gpz1100:
You are on the official sprint prl.... Who said anything about changing prls..... Go with it :)
[EVO 4G Android Development] GatoEnFuego:
You're missing the point. The Sprint PRL sucks ass (80kbps), on the VZW PRL I get 1mb and has been the savior of this phone for the last month. Now I'm not able to use the VZW PRL, only the Sprint PRL works.

Uhg, I was hoping it was a widespread issue and not just me... oh well.
[EVO 4G Android Development] jblazea50:
I can't use the 00001.prl either. When I do, I can't send texts or receive them. Always get an error. It doesn't allow me to update the profile either. So I'm stuck on Sprint's prl, which is **** throughout the day.
[EVO 4G Android Development] johncjenc:
Theres a variety of prls that work in diffrent areas. In my area the old alltel prls start w 4; ie 40065, 40051 etc. the verizon prls start w 5 and generally don't work, and the sprint start w 6. Trial and error on my end and I have it nailed down to four alltel prls that work beautifully. 1.5 mbps down. There have been times where tower maintenance disables it.
[EVO 4G Android Development] gpz1100:
No, i heard you loud and clear. Let me spell it out for you...Even if you're on the verizon prl, you don't tell sprint that. As far as they're concerned, you are on the sprint prl, and you've always been on it.
[EVO 4G Android Development] GatoEnFuego:
Haha, you still don't get it. My phone works on the Sprint PRL, it does NOT work on the Verizon PRL. If I call them and complain that my phone doesn't work, they'll have me update my PRL which will bring me to Sprint and all will be fine. The fact that the VZW PRL doesn't work isn't their concern nor would it do me any good to call them.
[EVO 4G Android Development] Hrshycro:
Can you link me to those alltel prls? I've never tried any in the 4 range, just 1s, 00001, 3s, 5s, and 6s of course.
[EVO 4G Android Development] frozndevl:
Missed this question, but here is my answer. You just call them up, say you updated your profile and your prl, but you are still getting the message that you phone cant be authorized. Mention that this has happened before and you called in and they reset something on their end. Should be fine, with no mention of VZW prls. Hell, they never even ask me to update my prl once I tell them I've already done that. By saying that, you are already well ahead of your average user so they can safely skip that step. Little do they know, you are way beyond the average user and doing something nefarious.

[EVO 4G Android Development] KB112:
Search in the thread, it's been posted a few times throughout it. I found mine buried quite a few pages in.

Are you running the EPST from 2.1 on a Sense Rom? If no to either or both, then this won;t work. You need to be on a Sense ROM with 2.1 EPST. Then you can chnage PRL and load up the AOSP rom you want. The PRL will remain whatever you changed it to.

Downgrading PRL version Sprint HTC EVO

You can also downgrade PRL version by downgrading the PRI Version which can be done with a quick flash (rooted phones of course) I updated to the latest PRI's 1.90 and 1.77 and was only getting 428 Kbps down and 543 up on average. I downgraded my PRI to 1.34 which in in turn gave me a 6062 PRL now after doing this with the instructions from this link http://androidforums.com/evo-4g-tips-tricks/280082-major-solution-fix-your-slow-3g-speeds-evo4g.html I'm getting average 2Mbps down and 500 Kbps up. awesome!!!!!! oh and its on 3G not 4G. IF THIS DOES NOT GIVE YOU DESIRED SPEEDS try the PRI 1.77 with PRL 60677. sometimes you have to play around to get your desired results. for those unsure no need to wipe when changing PRI's. OK DID FURTHER TESTING and found the combo PRI 1.34 and and the latest PRL to work good as well

So using the 00001 prl, my ip is still showing that it is under Sprint. Is that supposed to happen? I thought it would be a VZN ip since it is using their towers.
[EVO 4G Android Development] liquidtenmillion:
... Anybody else hear a loud woosh? He's saying call sprint... They will tell you to update your prl. This is where you say "I've already tried that, it doesn't work" You don't mention anything about a verizon prl. They well then reset your account on the server. Your phone will provision, and it will work, even on the verizon prl...
[EVO 4G Android Development] anthonylokrn:
So I ended up reading most of the 175-pages in this thread and found the answer to my previous question.

Currently have the 00001.prl loaded on my HTC EVO.

So even on a VZN prl, the IP address will still show the isp as Sprint. When I dial *2, it will connect me to VZN CS, so that confirms that I am connected to a VZN tower.

Since I'm using a VZN prl, my home network should be VZN, and my roaming network should be Sprint (correct?)

And since I'm connect to a VZN tower, any data usage will be logged as roaming data (?) I've read that if Sprint 3G is available in the area, even though I'm connected to a VZN tower, the roaming data will log as Sprint data instead (?)

What I'm trying to accomplish is to rack up enough roaming data to get out of my Sprint contract so I can move to VZN before they start the tiered data. Currently using a HTC EVO in Houston, TX; never drop calls, but spotty 3G coverage and WiMax is just pathetic.
[EVO 4G Android Development] frozndevl:
It will show up as VZW data if you are using the 00001 PRL.
[EVO 4G Android Development] anthonylokrn:
Thanks for clarifying that.

I've been checking my Sprint account online and still don't see any roaming data used even though I've been streaming HQ Youtube videos yesterday and most of earlier today.

Does anybody know how often Sprint update the usage?
[EVO 4G Android Development] Product F(RED):
Sprint's site is inaccurate as hell. If you look at your usage, it shows one number. If you go the plan analyzer and look at that, you're shown a totally different number. Try using 3G Watchdog to check your usage.
[EVO 4G Android Development] anthonylokrn:
Thanks for the suggestion.

I went back into my Sprint account to check the usage again and the Sprint Data went up, but the Sprint Data Roaming is still at 0.

How come the roaming data still aren't being counted?

Instant Messages not working

i have used maybe 5 different prl's and neither of them the messages dont work. what is my fix if any?
[EVO 4G Android Development] dmora01:
Yesterday I called sprint bc my 3G speeds were very slow and was taking too long to connect to the service and they told me that they have three towers i my area, tampa area, working at 50% and they did not know when they were supposed to be fixed so they cancel may contract in three lines and look for another company, I have been with them for 7 years, :(, I don't want to look for another company so my decision was to root my phone and use 00001 PRL and what a difference, night and day, I have full service every where and fast internet, text messages working and voice works fine, sometimes drops my 3G but comebacks in couple seconds.

I dont use a lot of internet close to 500 mb to 1Gb at month, 500 texts and close to 300 minutes in voice so I am going to see if they complain, but for know I am going to keep rooming with verizon.:rolleyes:

This works and it does force the phone to connect to VZW towers however i found that the latency jumps from 100ms on Sprint to 340ms on VZW so it seems like the traffic is taking a much longer route and thus the speed are slower. at least in the SF Bay Area.
