First you need QPST, I couldn't get any other version to work except 2.7 build 374. Downoad it, extract it, install it.
Download link: QPST 2.7.374.far

Secondly you need to know your MSL
If you don't, download MEID converter from the Play Store or go to whiterabbit.org/android. Enter your IMEI; your IMEI is found in settings>about phone>status, convert it and now write down that 6 digit number

1) Connect your phone to your PC
2) 2) Open Settings>Developer Options>USB debugging enabled (must be unplugged while changing the setting if stock).
[Let the drivers install]
3) Open QPST Configuration
4) Go to the Ports tab
5) Add the port that says Diagnostics
6) Press start client and choose Service programming
7) Make sure your phone is highlighted and press OK (from my experience the phone number will be wrong)
8) Press "read from phone" located in the bottom left
9)Enter your MSL
10) In the bottom right click on "Save to File"
[This will be your back up in case you accidentally did something you weren't suppose to.]
11)Go to Roam tab
12) Now browse for the PRL file you wish to install and choose it
13) Press write to phone, located on the lower left
You will get an error message saying your phone has stopped responding to read/write.... blahh blahh.... Phone no longer active on port x
Your phone will show that it has no service
14) Reboot your Phone
15)Your all done
To check go to settings>about phone>status

And here's a Video Tutorial

You may notice i changed some steps in order for the phone to be detected, the reason being that my previous method wasn't working anymore but this did.

Credited for 9033 goes to n4zty
Other PRLs provided by Gman9831and 2GigayteSD

Special thanks to Sammy for correcting me on step 2

Thanks to SwoRNLeaDejZ for the video tutorial

[SIZE=3] IF YOU WANT TO REVERT YOUR PRL DIAL *228
Choose option 5 or say update preferred roaming list[SIZE=2]

I just dial *228 and choose # 5, and it updates the prl automatically to the latest one.

Gman9831

People may want different prls on their phone like the ones that's exclusive to the s3

I did the same thing once I notice 9033 was garbage in the Sacramento area and it just restored back to the latest prl

Matthew83

Thank you for this guide. I had unknowingly done it correctly on my own but I thought it failed since it gave me that error at the last step, I didn't know that is normal.

I'm using 9033 and so far at my home in Southern California I notice no difference. I will keep using it for a while and might revert back to the default one later.

2GigayteSD

Garbage is an understatement....

Turn you're data on.
Doesn't matter just when you're browsing for the prl go to the location you saved it in.

MotoTriumphant

I went to work using prl 2032 and when I was done I tried to use GPS to get back home but it would just hang and hang it would just be searching for GPS and I never got it to work so I had to reset my prl by dialing *228 then press 5 for the latest roaming list then GPS started to work again instantly. Im gonna give 9033 a go.

sammyz

Did you try rebooting before changing PRLs?? Sometimes the problem is that the phone really just needs a reboot.

__________________

MotoTriumphant

I don't think so but im on my second day on 9033 tested GPS wherever I go so far so good

sammyz

Try again on 2032, I think it just needed a reboot

Fox Mulder

I don't see how the PRL would have any effect on GPS. It's only a set of instructions for how to use the cell/data network and nothing more. The GPS is a separate radio contained in the phone that works on its own regardless of network status.
Put the phone in airplane mode, turn on GPS only, and you'll still receive satellite signals and be able to use GPS-based apps as long as they don't also need live data. Try this with GPS Test.

MotoTriumphant

But gps needs data connection and 2032 was acting iffy for me

2GigayteSD

GPS does not need data to work. Google Maps needs internet to display the map tiles, but it will lock on to your cords...

sammyz

I still think the phone only needed a reboot

MotoTriumphant

So the app " Navigation " doesn't need data connection?

Fox Mulder

It does, to download the maps and route info. Once that's on the phone you can navigate with GPS alone as long as you don't deviate from the route.
There is also an option in the Location settings to use "assisted GPS" which does use network data to help the GPS determine location.
But for purposes of the discussion in this thread, using different PRL's should not make any difference with the phone's ability to lock onto a GPS signal. Most likely as has been speculated, the PRL flashing process locked up something in the phone and kept it from working properly until the next restart.

sammyz

It does because Google Maps needs iternet, GPS though could work by itself if you had all maps downloaded.

MotoTriumphant

Yea I was talking about navigation lol

cjbandroid

When I go to step 7 in the instructions I'm getting an error.

It says "Online connection failure: Unspecified Error"

When the phone is in USB tether mode, I can tether my PC from it, although its pretty slow.

Any thoughts?

MotoTriumphant

Try the charging mode one instead of tether. My tether one was grayed out and I couldn't use it so I used the charging mode and it also worked

cjbandroid

Got it.

My QPST was out dated. I saw the v2.7, but my build was old at 323. The new one is 374

On the "greyed out" USB Tether... that can happen. The fix is to go to airplane mode, then out of airplane mode, and USB Tether is restored.

Many thanks!

ps.. so far so good on the new PRL 9033 -

sammyz

Change that step to:
2) Open Settings>Developer Options>USB debugging enabled (must be unplugged while changing the setting if stock).


Your phone may be detected on a different COM PORT after that. Mine changed from COM 5 with tether to COM 6 with this enabled.

johnnyolivares

Will do. I won't even test it cause I trust you that much

kdellea

I don't get a port that says 'Diagnostics"

sammyz

A port that says Android?

johnnyolivares

Does any port show up?
If yeah, try it .
If it has a number even though its not yours, thats it. (Unless you have more than 1 phone connected.)

dakid27

will 9033 mess up 4g connection?

johnnyolivares

No. Might even make it faster I believe or slower. It all depends on your area

dakid27

did it make your 4g faster?

Gman9831

I tested all of them & my 4G was fastest on 2032 so I stuck with that one. I go to 9033 so i get Sprint 3G when I know I'm traveling in the boonies on my way going up to central Florida.

killermike

Witch prl would be best for the Texas area

Gman9831

Like I suggested above 2032. It gives me overall better speed then i'll use 9033 if im going into extended home area.
But im not in Texas

alfick3

Where in Texas? If you are in the DFW area, just use the 2032 that automatically gets pushed to the phone. Outside of that area probably the 9033.

2032 is only automatically pushed to S3 owners everyone else gets 3032 pushed but 2032 has overall better 4G speeds than 3032 for me.

alfick3

Doh! You're right. Brain fart and dyslexia on my part.

SwoRNLeaDejZ

Flawless guide. One thing I noticed, when I went to Service Programming, it did not list my phone number correctly, not sure if that is normal or strange, because the PRL installation still worked, PRL reads 9033 now. Was kind of hoping to grab some sprint service at my house, where I currently get HORRIBLE service from Metro (unless I leave my phone on the right front corner of my bureau, for some reason, I grab 4G there (?????)), but I did not see a dramatic improvement in my service throughout my house. I am able to get 1X coverage everywhere in my house for the most part, where before I just had a red X, so I guess that is definitely an improvement, just not as much as I had hoped for.

A+ tutorial though, very easy to follow, I am going to make a video about this, tomorrow night, and I will send you the link and you can add it to the OP, if you'd like (I have a YouTube channel full of tech tutorials, Android, PC, PSP, etc.). Thanks for taking the time to write this up, been searching for something like this for a looooooooong time. +1

Yeah the number is never correct.
At least that's from my experience.

I will gladly add the link. Thanks for making the video

SwoRNLeaDejZ

No problem whatsoever, I try to make videos whenever I find a solution after searching for an extremely extended period of time. This is one of those occasions.

sammyz

Make one for the unbrick guide that actually shows how to do it??

Current video:

SwoRNLeaDejZ

I could but my phone is in perfect customized condition, unbrick would delete all my apps and hard work... someone sends me a phone, I'll make the video with a smile on my face. Like I said once before, if my phone ever requires an unbrick, I will gladly film it.

johnnyolivares

How about you just have a back up?
