[How To]Change Your PRL!! Faster Data! (video tutorial)

EDIT: Read the second post for more info/alternate hybrid PRL/how to revert back to stock! I know it's a read but it should answer any questions you have!

This is a video tutorial I threw together on how to change your PRL. There has been some confusion as to how to change the PRL/some people having trouble doing it. I hope this helps!

WARNING!! Use this at your own risk! People have had their accounts terminated by using too much roaming data.

That being said, I've used this have for a few months now, and I haven't had any trouble, but others have.

This hack loads a new PRL onto your phone. It tells your phone to use roaming data instead of Sprint. Normally you only roam on 1x, but this makes you roam on Verizon's 3g all the time. In my area it is over 10x as fast as sprint. In my house (with 2 bars) I get 1.3 mb/s average download, and when I have any more bars I get well over 2 mb/s consistently. This is compared to dial-up like speeds on Sprint...


Let's get started, shall we?
---------------------------------------------


Links for the downloads are below!

Watch it through and follow the directions. This will work on most ROMs, One I know it will work on is Codename Android 1.4. Here are the directions in writing:

1. Get your MSL number. Do this by getting an app from the market called terminal emulator. type in:
su (hit enter)
getprop ril.MSL (caps sensitive, then hit enter)
your MSL will be there. It will be a 6 digit code. Write this down for later!
You can also call Sprint and if you ask nicely they may give it to you!
2. Install drivers for your device on your computer. Look up a Youtube tutorial on how to do this. It was the hardest part for me.
3. Download the file "00001.prl" and QPST. Links to both are below. On your computer, extract the QPST file, open it up, and double click on setup. Go through the installation process.
4. Go back to the phone and open up the dialer. Enter this: *#*#8778#*#*
5. On the menue that pops up there will be a secton labeled "USB". Change it from PDA to "Modem"
6. Back to the computer. Hit the start menu and open up device manager. Double click on "ports" and you should see your devide there. at the end it will look like this: (COM#). Write down the number at the end of the COM.
7. Hit the start and search for QPST and open it. At the bottom corner click on new device, and when it asks for the port enter COM# (using the number you found in the last step), and hit ok.
8. Now go to "start clients" and hit "SERVICE PROGRAMMING". It will ask what port you will be modifying, just click your device and hit ok.
9. there will be these tabs with CDMA, CDMA-2, ESN, etc. Click on the one that said "Roam". In the lower box hit browse, and find the 00001.prl file. hit ok.
10. Finally, hit "write to phone". The phone should reboot, and you're done!
11. I forgot to add this in the video. Once it boots up, go back to the dialer and enter the *#*#8778#*#* code again. Change it back from modem to PDA and you are done!

Post your results! How are your speeds before and after? Use the speedtest.net app to test. And don't forget to hit the thanks button!

So due to the rumors circling, I decided to clear them up here.

Read this before posting!

These are the drivers I use with my Nexus s 4g:

The PRL I included in the first post will make your phone work on VERIZON! It shows up on your plan as roaming data. If you use the 00001 prl then you DO NOT have to make your phone force roam or anything of the sort. It just works on Verizon, and your phone will NOT show that it is roaming, yet it is. Got it?

When you flash a new ROM, the PRL isn't touched. So you don't have to redo this if you flash a new ROM. Also, if your ROM doesn't do anything with the dialer code, then make a nandroid of it, flash a new ROM (I know for a fact that CM9 V3 and codename android 1.4 work), do the hack, then restore your nandroid. It's a little round-about, but it works!

How to use BOTH networks:
======================================

Now you can use a hybrid PRL. These have you on Sprint and they allow you to use the Verizon 3g if you force roam. I used this on my EVO 4g, but I haven't had great luck with it on my Nexus s 4g. Others have. Try it out if you want, here is a hybrid PRL (11114):
http://www.box.com/s/yrml7pzfgjc1od8hbp2j
You apply it the same way as the 00001 PRL.

Once it is installed, you will still be on Sprint's network. If you want to make your phone work on Verizon, then you have to make your phone force roam. You can do that with this app: roamctrl.com

Now you can switch between using Sprint and Verizon 3g!

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


Reverting back to stock

If you want to go back to the stock PRL, you have 2 choices. Both of which are pretty easy.

The first would be to go an official Sprint ROM, go to settings>software upgrade>update PRL or settings>about phone>update PRL.

If you are on a ROM where you can't do that, then you can just put the stock PRL on your phone using the same method that you used to put a custom one on.

As of this post, this is the latest sprint PRL:

Download it and use QPST to put it on your phone. Easy as pie

Finally some info on Roaming on Sprint:


Now your plan includes "unlimited roaming data". Sprint, however, says in the fine print that if you go over 300mb you can get into trouble. I have used this hack for 4 months using 1-1.5 gb of data. Never had a problem. I only know one guy first hand who has ever gotten kicked off their plan from this. So know it is a possibility, but unlikely. And they send you a warning letter before they kick you off. If you get the letter just revert back to the stock one!

If there is anything else I should add here let me know!

Interesting. Will this give me over charges for roaming then?

Roaming is unlimited on Sprint's unlimited data plan. So nope!

Be very careful with that 00001 prl. There are others like 11115 etc that won't get you in any trouble.

I used to use that PRL on my EVO, but it isn't working on this phone. It was just using Sprint even when I force roamed.

I'll use the 00001. I've used it for 4 months and had 1-2 gigs of roaming data. No Trouble yet!

I can! haha I've done it on 2 different phones and many many ROMs.

Coycaine said:

I hope you never do(have trouble that is)! Did you use it (00001) on the Evo as well? If you did, did you notice any speed differences between that and 11115? And great video by the way! Especially for your first on youtube!

Thanks! It is just my first video on this channel.

I did use the 00001.prl on the EVO. I ended up using the 11115 on my EVO as well. It worked ok on that phone, but I wasn't getting data as fast as the 00001. And I couldn't get the 11115 to work on my Nexus.

Warning!!! Do NOT do this hack constantly! I personally have a friends who did this on his Evo for about a month straight and Sprint sent him a letter and ended his contract with no fees. His service was terminated within 2 weeks of receiving the letter from Sprint.

Edit: yes, he had unlimited roaming on HIS plan as well. So there's little truth behind Sprint's claims.

There are whole threads on this over in the EVO 4g forum. OF the many who use this hack only 3 or so have had this happen. And they weren't the heaviest users. If you get the letter then just undo the hack and you're fine!

Sounds like a win win to me! Use Verizon speeds while I'm under contract and then IF Sprint terminates my contract I'm free and clear to take my NS4G to boost or go get the (Insert latest new device) as a new customer with no ETF's???!!! YES PLEASE

On a side note, would this have any effect of 4G? I ask because I live in a no 4G area on Sprints network but Verizon has 4G in my area. Just curious if it would give me 4G as well. I have no idea how 4G networks work as I haven't ever used it.

A lot of people use the hack to get out of the contract. They use crazy amounts of data to get noticed. Funny thing is, most of them haven't gotten "the letter" yet. It seems almost random.

And this wouldn't give you Verizon 4g. Totally different radios.
