PRL Swap for the V on VM (latest PRL for Sprint Towers).

[thadass]

I wasn't able to get CDMA Workshop nor QPST to work with an IHO rom. I restored an old backup of aospCmod I had and then everything worked like a charm! I changed my prl to 60685. every day for a week I've done a speed test and gotten 512kbps which is the main reason I searched out how to do this prl swap. with 60685 I was immediately getting 1Mbps! Hooray! (still not that great I know but... twice what it was!)

When I had swapped my PRL, I was having issues getting CDMA Workshop to recognize my phone (driver related?). I tried using it with the IHO recovery to no avail. However, I was successful using Xionia recovery. I like the recovery method more because I think it's a lot faster switching recoveries versus switching ROMs.

Where can I find the most recent PRLs?

Thanks to all that have put in all the hard work on these phones. I'm really enjoying CM 7.

Follow this guy on the XDA forums if you really want to keep track of the latest. He also maintains this site BatonRougeBroadband.Info - Home where he puts up PRL analysis info so you can search for your city in each PRL to see if there were noticeable changes. I'm not going to pretend I can explain what the analysis files mean except as networks buy cell tower space on other carrier's towers I assume the PRL's tell your phone what new towers or frequency changes Sprint (Virgin Mobile) now have access to in your area. That's my gist of what I gather PRL's do for you.

As of this post the latest applicable to our phone that I've used is 60686

 

[gopickett]

Thank you for that link. I'm pretty much up to speed on prls but I'm not sure where to find the latest available. Where do you (and anyone else reading) get yours from?

 

[anon(235100)]

My apologies. Here's a link to prl 60686 I just uploaded to mediafire. I was doing a little googling earlier today & found it but usually I search on the xda forums, android central, howard forums or just google.
There's really no specific place because these PRL files are coming from Sprint users who get them via over-the-air updates after dialing things like *228 on their phones and whatnot. Since our Optimus V originally comes with one from Virgin Mobile numbered 61007 (I believe) and Virgin Mobile doesn't offer an update mechanism it's really just hunting for them.
I've found a few troves of PRL's but nothing shows when they were new or not. Searching on any forums for PRL's some user is kind enough to pull the PRL from their phone with Qualcomm Phone Support Tools every now and then.
Here's another link to a bunch of old PRL's. And another of even older PRL's.

Easiest thing is go to that baton rouge site & see digiblur's analysis info on latest ones and pick the ones following the 606xx numbering convention because some other numbering conventions are for corporate phones, some are for air cards... the most adventurous I get is keeping in the 606xx numbering convention and I've been fine.

Actually, on XDA I saw a PRL 60687 came out a couple of days ago but no one has uploaded it anywhere to be found. I really don't think it's important to update them often but it's one of those habits to find something new

If you can't tell my knowledge is sporadic at best just from skimming over people talking about things like numbering conventions. The smartest thing, really, is sticking with stock or calling Virgin Mobile and seeing if they'd ever consider an update mechanism. Considering it's a cheap network - and that Sprint probably doesn't care about providing Virgin Mobile users up to date- we have to make do with hacking away.

Thank you very, very much. I always wondered from where the PRLs came from. Thoughtful Sprint users, so nice of them.

I noticed 60686 (6.76KB) is slightly smaller than 60683 (6.78KB). I assume at some point they trimmed some towers off.

Just letting everyone know I flashed prl 12120 and this is the speeds I'm getting.

PRLs don't determine the speed. It just determines which towers you can connect to. In all likelihood, it's the same tower you connect to with the stock Virgin PRL. Do multiple speed tests and you can reach all sorts of conclusions about which PRL is better than another, with the only real conclusion being that speeds vary greatly. That is, unless you're actually connecting to a different tower as a result of the PRL change.

I know all about this man.. I'm not new to anything. I have done plenty of tests and the speed is the same if not better. I was posting this showing that the prl must have changed my tower preference. Which obviously it did.

Very cool, can you share with us a link to download that prl please?

The latest PRL was just posted today, see:

I notice it is a corporate prl. I'm guessing VM users have been able to use this Sprint corporate prl with no problems? Can they even find out?

 

[thewraith420]

I'm posting on it now... Just installed it.. Even if it didn't work it wouldn't be hard to change back

That's good to hear! Do you see a difference? Which program do you all use to check to see if there is a difference in towers? Signal Finder?

I haven't gone anywhere yet to be able to tell... At home its about the same as far as I can tell but I'm coming from 60686 and it's been better then stock for me.... Really its irrelevant anyway tho. Your results will depend on you area

I downloaded vmware and having a problem putting cdma workshop on it because its visual machine. How can I put it on there without giving me problems?Please let me know

 

[Conrail16]

Why are you using a virtual machine? You should be able to get CDMA workshop running on it easily enough (assuming the VM is running Windows), but I'm not sure if VMware even supports vritualized COM ports (which is what it needs to get your phone detected)...

 

[amanda41943420]

yes it supports ports because it detects my drivers for my sanyo congonito. But I cannot get vmware to open cdma . I cannot get my regular computers to even detect these drivers thats why.
