Maybe there's a bug in 1.4. It's not as if the developer updates it for no reason.

All I know is I have the latest version of RC + 11115 PRL and my roaming speeds are fast.
[Epic 4G Android Development] jfg69:
Thanks for the detailed how-to, worked like a charm. However.. I have a sort of noobish question.. (which I havent seen an answer to) under roam settings, under roaming guard, do the boxes get checked or unchecked to allow roaming?
[Epic 4G Android Development] digiblur:
Your phone either roams or doesn't roam. 1.4 worked fine for 3g roaming before. The updates on RC were not because of the Epic.
[Epic 4G Android Development] dchawk81:
I'm not saying it definitely is Roam Control. I'm just saying it might be. I've heard technicians say "It can't be that.There's no way it's that" many times before about different things...and it turns out to be what they said it couldn't have been.
[Epic 4G Android Development] digiblur:
Awfully quiet from the folks claiming a cap :) waiting on the confirmation of the PRL version and indicator on the mobile signal widget.
[Epic 4G Android Development] A_Flying_Fox:
I cant flash the prl cuz my computer is down. Revert to 1.4 and try it. I updated profile and it reverted me to 60681 so im back to square 1 till irene passes
[Epic 4G Android Development] digiblur:
I used 1.4 for quite a while since I had to due to sprints data being down in one area for a year. 3g speeds were not capped. Don't have that version anymore since I upgraded to one of the GB leaks.

Glad you guys only got a piece of Irene's fury. She was mean looking several days ago.
[Epic 4G Android Development] lbe:
Just verify with signal widget said i am on 1xRTT as confirm with speedtest despite the icon on epic said 3g. ##33284# also said i am connected to 1x. Same result tested in new jersey, nyc 5 borough and Long island. When i used to have touch pro i was able to 3g roam on verizon full speed. Also salme result with 11114, 11115, 01120, 60680

SID4162 when in sprint, SID22 when roam

I called up sprint and they vaguly told me it was correct that i am suppose to roam at 1xrtt in my area.

dchawk are you from nyc?
[Epic 4G Android Development] dchawk81:
I'm in Pennsylvania. Is there a particular reason you're not on the latest RC?
[Epic 4G Android Development] lbe:
Only version that didn't need liscense check, I doubt it has to do with rc tho
[Epic 4G Android Development] digiblur:
Bingo! 1x.

Check the PRL analysis for those SIDs and make sure it has. EVDO scans enabled on VZW.

Now if EVDO is only on the PCS band in your area then you are screwed. The Epic has had a bug since day 1 that prevents it from roaming on PCS networks.
[Epic 4G Android Development] lbe:
SID: 22 - Verizon Wireless - NEW YORK NY - Priority: Same - Roaming Ind:Domestic

1X Scan: CLR/Both CLR/Both

So it means its pcs only?
[Epic 4G Android Development] dchawk81:
I figured it was 1x. That doesn't prove anything. The question is why is it only connecting at 1x. I don't know what the data in the previous post means though.
[Epic 4G Android Development] A_Flying_Fox:
The data in the post means that the prl allows roaming on verizons pcs bands I guess

Idk what clr is

Man what a ripoff :/ I don't remember the prl I had before sprint started going on a prl update spree and took out 3g service all together in the middle of the country lol that was the prl where they killed the contract for 3g roaming right?
[Epic 4G Android Development] digiblur:
CLR is cellular band. Just because the phone scans the clr band doesn't mean it is there though. I would be curious to know if someone with a PCS roaming capable phone can roam there.

Try loading that hacked 00001 VZW PRL and see if you can roam. It should work on the pcs band on the epic since it won't see it as roaming. Then check the debug screen and see what channel the evdo is on.
[Epic 4G Android Development] lbe:
First I would like to say thanks to digiblur and dchawk to help us diagnotic the issue.

Loaded 00001. phone used sid22, channel is 850 90% of the time and sometimes jump to 507. speed test is showing 1.5-2.0 mbps. faster than sprint network.

With 11115 while roam phone used sid22, channel just keeps jumping to different numbers and cant stay lock ( is this also why every time i roam the battery goes down the drain?)

With 11115 without roam phone used sid 4162 evdo channel jump around 675,650 and 425. (speedt test is btw 400-900)

So it looks like when roam we are suppose to go pcs850 for evdo but due to the bug we are not able to. Is there a work around for this issue? eg. any tool to force a channel and sid on the fly or custom rom?

It's not a viable option to write 00001.prl everytime i travel into a no sprint signal area. Does the nexus s 4g and the upcomming galaxy s2 also affected from this? If so i guess i can only get HTC phone from now on for sprint network.
[Epic 4G Android Development] A_Flying_Fox:
just flashed 00001 and im still capped :/

well

now its 125kbps with a ping of 1092 :(

what am i doing wrong :(
[Epic 4G Android Development] digiblur:
850 is a pcs channel. The epic won't use it while roaming.

I have seen this issue with my own eyes. Touch Pro2 in one hand and Epic in another. I was in an area with no sprint signal and verizon pcs signal. Epic had no signal, TP2 had full signal. Gotta love Samsungs bug in the modem they still haven't fixed. It would work out real well if you only had the epic and needed to call 911..no dice...even if the vzw signal was right there.
[Epic 4G Android Development] Grommish:
Without RC my phone roams to Verizon if its a better signal. I spent 3 days surfin the vzw because the local tower was down.

60681.. I've not done anything to the prl.
[Epic 4G Android Development] dchawk81:
You didn't roam because it was a better signal, you roamed because it was the only signal. And it was probably at 1x speeds.
[Epic 4G Android Development] lbe:
00001 is a verizon prl, so without roaming and stuff your phone will auto jump into verizon sid22 when boot up. The evdo takes a bit of time to lock tho. So it means your phone threat it like a sprint prl but in reality you are roaming. I wouldn't suggest for a full time roam tho.
[Epic 4G Android Development] digiblur:
Fixed your post.

Mine roams to VZW Cellular Band too. VZW PCS band..not so much.
[Epic 4G Android Development] lbe:
Can still roam at 1xRTT to place call and slow data, just no evdo roam where I am at.
[Epic 4G Android Development] mentaldelusions:
Is the samsung radio but just on the epic? I'm considering getting the sprint version of the galaxy s2 when it comes out but if it also has this problem that might be a deal breaker.
[Epic 4G Android Development] NeoGauge:
So I read the first part of this thread. Is there a better way to update my prl to force roam at my house? I barely get a signal and it roams with almost full bar but it always jumps right back to Sprint service. Leaving me with no service or 1 bar.
[Epic 4G Android Development] mentaldelusions:
to force roam just get roam control from the market
[Epic 4G Android Development] MДЯCЦSДИT:
Where do I find 00001? And what modem and prl combo is best?
[Epic 4G Android Development] notmyepic:
[/URL]

Actually surprised that I found it.

00001.prl

I just installed and am using the Eh06 modem. Will post results tomorrow after I test on the way home and at work.
[Epic 4G Android Development] notmyepic:
My tests with the 00001.prl was alot better reception at work, but hardly no signal at home. Also since *2 now calls Verizon (and I am always calling Sprint) I am back to the 01115.prl
[Epic 4G Android Development] ericwgarza1:
Does anyone have the 22081.prl file? It appears to be pushing out to some phones at the moment.
[Epic 4G Android Development] digiblur:
00001 puts you on Verizon data and voice 100% of the time, so of course *2 would call them.

01115 and roam control seem to be the best combination so you can control when you are on VZW.
[Epic 4G Android Development] dito33:
There is no prl like 01115 or any other that can come close to 00001 when using 3G. Top my 2500 down and 900 upload.
[Epic 4G Android Development] digiblur:
11115 force roamed and 00001 not forced roamed will have the same exact results since it uses the same setup. Unless of course you are in an area where verizon only has evdo in the pcs band.
[Epic 4G Android Development] rmorrisonva:
Question

Last time i used QPST to update my PRL my WIMAX settings (accessible through ##DATA#) stayed the same. Is this normal (mine had been customized and i just figured a PRL update might overwrite them). Or is the PRL separate from whatever sets or could overwrite the WIMAX settings?
[Epic 4G Android Development] dito33:
I never was able to use roam control with success even payed the latest 1.63v am I missing something. Went back conventional way with QPST.
[Epic 4G Android Development] Suprize3131:

[Epic 4G Android Development] Dulanic:
If I use verizon PRL's or the 00001 prl i seem to get lots of FC's. I followed the directions step by step. I went back to the Sprint PRL and now the FC's still exists. I reflashed my ROM and they still exist. I am going to try an odin reset next.
[Epic 4G Android Development] dito33:

[Epic 4G Android Development] mentaldelusions:

Im currently on 60681 is this the standard right now?????
[Epic 4G Android Development] ericwgarza1:
I don't think so. I was on 21081 before I manually updated to 22081. Pull that PRL off and post. Instructions for pulling off you phone are HERE.
[Epic 4G Android Development] digiblur:
Bet you are have journaling turned off and your data got corrupted when qpst rebooted the phone. PRLs will not cause FCs.

[Epic 4G Android Development] Whosdaman:
The most up to date PRL's are the best to use by far for any network. Using an older PRL can cause decreased signal and lost of roaming ability.
[Epic 4G Android Development] m5james:
Even running my current ROM & kernal, I have no issues updating my PRL. What I still can't stand (something that even happened on my Moment) is my issue w/ receiving picture mail and even plain ol' text messages. I know I'm not getting all my MMS' when I check pictures.sprintpcs.com, but I've been told after the fact that I'm not receiving texts as well. I've refreshed checking my PRL everytime I go into a new town, yet this still happens.
[Epic 4G Android Development] swanysto:
It worked great, hopefully I will get less downtime now.

Off topic question. I can use the MSL code I obtained to do a factory reset correct? #7780#
[Epic 4G Android Development] Leviuqse:
yes, you can also use that code to reprogram most of the stuff in your phone with a few exceptions

[Epic 4G Android Development] ruben8448:
I was on the latest sprint prl update, the 60674 and my signal was the worst I have ever seen. I don't believe I could go over 200kb. So, I down graded to 60671 and service has been amazing again. I now get an coverage of 800kb to 1.6mb. I live in the phx area so it really works here. I don't know if anyone has done this and received the same results as I have.

hi, I experienced the same rollercoaster signal last weekend when i was on a poor sprint coverage but very good verizon one. when the epic went to roaming, it started doing that..

I know this probably doesnt really help you a lot, but may be someone who knows more than us can tell us what is going on..

[Epic 4G Android Development] scottyd035ntknow:
Question, if one happened to have a Sprint phone on boost's network (no roaming) is there a way to modify anything with the PRL to force it to allow roaming like loading a Verizon one or would it not work. I live in the Northeast where basically every carrier has good coverage but it would still be nice to have the option.
[Epic 4G Android Development] Leviuqse:
for some reason...roaming now works here in south florida on boost mobile..us boost mobile users didnt used to be able to roam....

:confused:

you should try and upload a verizon prl to your phone and see what happens..worst case scenario will be that changing the prl will make Betelgeuse go supernova...lol..jk
[Epic 4G Android Development] gullzway:
My 3g has been messes up since I updated my prl manually to 60674. Ive reverted back to 60669 and also tried 60671 but it's still hosed. With speedtest in an area I normally used to get 1.5 Mbps or more, now getting < 100 kbps

I've checked settings in ##3282#, gone back to stock, factory reset and I can't fix it.

Any suggestions?
[Epic 4G Android Development] gullzway:
Have you tried the app "Roam Control", it can force Roaming.

I fixed my Slow 3G issue After Several Factory Resets, Some QPST Programming, and extracting the PRL off another phone.

Kind of off topic here, but

I'm not sure this is 100% accurate, well assuming your statement would apply to 01337 as well. I was in long branch jersey the other weekend and with 01337 I got no service at all, with 11115 set to roam I had service. Don't think I checked whose tower I was connected to though.

Use the Sprint 11115 PRL, same thing as boost and is very current. Case in point, I still have not updated my wife's PRL to the latest and she is operating on one that is probably 4-6 months old. We ran through a very rural area and I never lost service while hers was doing the signal gone beep every 5 minutes.
[Epic 4G Android Development] digiblur:
11115 should no be used on boost as boost does not have roaming.
[Epic 4G Android Development] scottyd035ntknow:
Your point being? It has been the best PRL for me through empirical evidence, IE, I get way better receptions than I ever got before. It isn't like the 11115 PRL won't work on boost, you obviously will not get roaming but if you live in a state like I do with literally blanket Sprint coverage then who cares?

I have tried the 11115.prl, the 00001.prl, and a Verizon 52515.prl. I get no data other then 1x. I live in the Chicago land area is anyone else having this issue? One thing to note I am using the Epic Touch 4G but I don't see why that would be an issue.
[Epic 4G Android Development] scottyd035ntknow:
One, its odd that your phone is even displaying 1x as Sprint has them all set to display 3g at all times. Unless you are checking for EVDO Rev A in the dialer menu... Um... you should be on 3G in Chicago, hell they have Wimax there right? 11115 is a legit Sprint PRL, I would put the phone back to stock and take it in for warranty/insurance exchange if it still won't work.
