[Q] Revert to a previous PRL - Sprint Samsung Galaxy S III

I'm stock rooted.
About a week or 2 ago I did a PRL update, putting me at 25015.
Ever since, ALL of my calls get dropped. Sometimes I can talk for 15 minutes, sometimes 30 seconds.
Call drops and I look at the screen and it says "lost signal", yet I'm showing like 4 bars for signal and not roaming.
I've done nothing else to the phone except update the PRL, so I can only assume that's the cause.
Is there a way to revert back to the previous PRL?

Really doubt it has anything to do with prl. PRL is preferred roaming list, it's for roaming only.
It sounds like your area is undergoing Network Vision upgrades. That's exactly how it was for around 2 months for me until they finished my area.
Have a great day!

The PRL shouldn't do that. However, all you have to do is go Settings > System Update > Update PRL. It will refresh the PRL with the latest from Sprint.

Thx guys. Yea, I didn't think a PRL update should cause this, but like I said it was the only thing I did when this started happening.
Ahh well. Coincidence.

Try resetting the phone on the network. Dial ##72786# in the dialer this will reset the device on the sprint network. It will cause it to reboot.
Have a great day!

Yea, tried that last night. It did it's thing. Still the same issue.
I've been stuck where I'm at for like the last week and a half, so I haven't had the chance to try a different location.
Hopefully, it is just a Vision upgrade at my location, cause dropping calls like this is just unacceptable.

Did you try this??

Why is my phone stuck roaming?

All my phone does is roam now and I have no idea why. It roams at my house and everywhere. I just updated the Profile and PRL and it still does the same thing. It should be noted that in the past month I was messing around using Verizon's PRL. I am on Myns RLS 5 and using netarchy 4.2.1. Not sure how to fix this.
Any ideas? Thanks.

Usually updating the PRL undoes the Verizon PRL hack. If you want to be able to switch back and forth between Verizon and Sprint without that hack, download Roam Control. I would get it anyways to see if it'll fix your problem.
I updated the profile and prl in that order and am on Sprint now but still roaming...in a place where I know that I have never roamed before. I don't know what to do.

How Can I Check My PRL?

How can I check my PRL? I see that a new PRL version, 60677, is to be comming out? I understand more then likely I have 60676 but I would like to check this is some way. I saw the way to "manually" check it but that led me to the thinking, is there a "automatic" way to check the PRL? Something where I can check it w/o plugging it into my computer?
Thanks,
Aaron
Settings/About phone/Status/PRL Version
Also the prl version 60677 got pulled from sprint so if u update it to that, sprint will revert it back automatically while u sleep or when u least expect it.
To update it prl: Goto Settings/About/System updates/update prl.
Thanks. Yes I am on 60676, what is the difference in 60677? It seems to be a big deal. Is this for that huge voice and data coverage drop?
Also, my network is "ACS" is this anything special or just a little "Advertising"

I believe there was a description of the changes in the prl thread...
But apparently helped roaming issues also enabled 3g while roaming from my experience, but it reverted back as i said sprint pulled it
What about the "ACS" network?

That is purely cosmetic...
Has nothing to do with sprints network, mine says emotionless beast cause its part of the theme...
Doesn't matter what ROM you are on. PRL is the roaming and which towers to use. Hit Update PRL once a month, if you have a new PRL available it will install it.

[Q] phone will not let me do anything while roaming. any ideas?

so i was running the VR_GengerSense_Revolution_B4 rom about 4 days ago with now problem doing ANYTHING on my phone while in digital roaming. then i left the roaming areas and went into sprint service area and came back into the roaming area and now my phone wont do anything while roaming. i cant make or receive calls or messages or use any apps or the net. i have 2-4 bars of signal but if i try to do anything it tells me i have no network connection. yesterday i switched to the BeKinged-STOCK-Beta-V1-Clark44 rom thinking that changing everything would fix it but it didn't i went back into that same roaming area today and its the same story. does anybody have any idea of what i could do to fix this? I'm at a loss i tried every setting and was on the phone with sprint for about an hr. and nothing. Ive tried different radios and still nothing. i was thinking of un-rooting and seeing if that changed it. it baffles my that it just randomly started with out me changing anything on my phone.
thanks for any input.
i updated the PRL tonight hopefully that will help \. gonna try that before i un-root.
PRL update didn't help. unrooted taking it to sprint tomorrow.

[Q] Sprint PRL's

Anyone know how to pull the PRL out of the Galaxy Nexus? I tried the *#*#8778#*#* that worked with the NS4G & QPST, but no dice. It would be nice to be able to use something like the 11115 PRL that allowed 3g roaming on older/other phones. I tend to get stuck in areas that have zero Sprint coverage for work a lot of times.
EDIT: *#*#3424#*#* Will put you in the right menu, I'm still working on figuring out how to get QPST to recognize the device though.
EDIT #2: From what I've been reading, the Galaxy Nexus will not work with QPST because it is not Qualcomm compliant...need to find VIA/Spirent PST to be able to do this? Anyone have any input regarding this?
I found a way to change the PRL. I'm not 100% sure that it actually changed the PRL and not just the number that shows in the menu though. The idea came from this thread: http://forum.xda-developers.com/showthread.php?t=1639839
So using Better Cut I followed the first step he outlined, JUST THE ONE ABOUT THE PRL THOUGH. Phone went through and did its reboot came back up.
At first it showed unknown as the PRL, MIN & My Phone Number. I went into *#*#yourmsl#*#* checked under edit and my info was correct, checked under *#*#3282#*#* and my username was correct in the data profile. Went back into about phone and everything had repopulated correctly.
Now where I am sitting its still showing me as connected to a 1xrtt network, but that very well could be because I'm in the middle of WY at the moment. I should be going into SLC tomorrow and I will try to force it to roam while I am there and see what happens.
Seems the post has been edited and no longer has instructions.
1.Download Better Cut (Google it)
2.Install on your phone however you see fit. I just downloaded the apk to my phone and installed from there.
3.Copy your chosen PRL to the root of your SD card and rename to Test (so instead of 11115.prl, it will show up as Test.prl)
4.Create a shortcut using Better Cut, go "Activity", "PRL Write"
5. Go back to where the shortcut is and click it. The phone will reboot and shortly after the PRL should show up in the "About Phone" section of your settings menu.
My friend just got a sprint nexus and he needs to force roam on it. His palm pre had this tweak working.
I've been using corporate PRL's on every phone I've had with Sprint and up until this phone, it has been very easy to do. From what I've read none of the traditional methods work because this phone does not use a Qualcomm chipset for the radio, it is using a VIA chipset. I will report back tomorrow if this actually changed the PRL or if it just changed the displayed numbers. It's hard to say in WY whether or not 3g service is actually available and from what I can tell I am rather far from the tower I am connected to.

The PRL should auto adjust as soon as you change regions. If its not changing and you're experiencing bad reception....etc...contact Sprint cause chances are you aren't alone.

Actually none of the phone's I have used with Sprint in the past few years have changed as I moved around the country. The point in all of this is not about bad reception really, just that when roaming certain PRL's you will get 3g roaming as opposed to the regular 1x.

PRL's CAN be region specific. However, some networks (Sprint included) Only have 2 or 3 different PRL's (Virgin mobile's...etc..) So whatever PRL you have now should be fine unless Sprint lights up new CDMA networks or adds more spectrum. If you have an old PRL (dunno what revision it is, I'm on VZW) update it with ##873283#. Any connection issues you're having likely aren't the PRL and are probably more related to carrier issues or the notorious Galaxy Nexus Data Drops that almost every version of the phone has had.
Edit: You could always try the Sprint Partners PRL's...dunno if it will work though.

Smokeey, I don't doubt that they can be region specific. But again, the only point in me doing this is for times when I am actually roaming due to the places I go for work. Ex: I have been in Wyoming for 5 weeks now, Sprint has Zero coverage here. So again it isn't about connection issues. It's about EVDO vs 1xRtt while roaming. The only time I use Roam Control or similar functions are to test the ability to get 3g while roaming.
Aside from that, I do not think this is the best way to go about changing the PRL manually on this phone, but for now it will do.
So .... with the 11115 PRL I was only getting 1x in WY, should have been 3g. Today I got into Salt Lake where there is Sprint coverage and I was still roaming, with the phone and Roam Control set to Automatic. I restored a backup of the stock ROM, refreshed profile, updated PRL and was back on Sprint 3g. Then went back and forced the manual update of the PRL back to 11115, tried switching to roam only mode and the phone stayed connected to Sprints network. By the time I got back into WY and was roaming again, it did properly switch to a roaming partners system and I still had 3g coverage. So it seems that everytime you write the PRL with Better Cut, you could get a different result. FOR ME this is fine, as long as it works when I am actually roaming.
I'm sure down the road a VIA compatible PST and associated drivers will turn up so that this can be done in a similar fashion to the way it was accomplished with QPST on other phones. But for now I am content.
I've linked to your post in my thread for how to update PRL manually. Your post was first.. so it's only right
and for completeness... here is my thread detailing how to use VIA tools the same way we used to use Qualcomm tools. I've linked back to you in the second post which details PRL writing. It looks like even with VIA chipsets.. we aren't so locked out after all.

Looks good, I'll give it a shot soon. Hopefully it will work in a VM, stuck with 64 bit on my laptop....

PRL write not listed in any cut or better cut
I can't find "PRL write" in either Any Cut under activities or Better Cut(v3.3) under all activities. I have Test.prl in /sdcard/. I'm running a vzw gnex on CM9.1. I've tried changing it's name to TEST.prl. I've tried several different prl files.
Anyone one have any advice.

Roam control works for you?
Do we know of another way to change the MSL?
I prefer mine to be 000000, but with QPST not reading it I'm stuck.
I could try and dig up a CDMA workshop, but most of those are virus ridden, and i'm not sure it would connect to it either...

I have used this method, but through apex launcher, Also tried it using Sprint Diagnostics options, guess trying bettercut wont hurt. I have the same issue as far as my info reflecting correctly using *#MSL & *#DATA but I have "Unknown" showing up in the My Phone Number, MIN & PRL fields, but they never repopulate for me. Any hints on what could cause this?
Thanks in advance

When to update PRL and Profile?

What do these exactly mean anyways? Im new to Sprint and i was told to update them every once in a while every week. I have an airave at home and i got a little confused. Do i have to update PRL and profile when im home to sync with the air rave and then Update PRL and profile when i leave to sync with the Towers?
Im also supposed to be doing this as we're getting LTE vision towers installed in the area..
PRL > prefered roaming list...update it every once in a while, it won't change weekly. The air rave just spits out 3G so it can be optimized. PRL helps you to connect to more towers, hopefully yielding better coverage. So you can update the PRL and profile where and whenever you like; just be on a tw rom to do so.
