[Q] How to change PRL - Sprint Galaxy Note 4 Q&A, Help & Troubleshooting

Has anyone found a way to flash / change the PRL on the Note 4?

I found a way to flash a PRL. I was able to successfully load older prl that are withing the same series. I used DFS CDMA TOOL v. 14.10.21.0.
1. Turn off wifi and data on the phone.
2. press ##3424# on phone.
3. Qualcomm usb setting
4. Select RMNET+DM+MODEM.
5. ON DFS Click on port on and select the port your phone is displayed.
6. Enter your MSL right below.
7. Once you enter the MSL click the SPC icon.
8. Next click on NAM.
9. On the bottom right hand corner click Load and select the PRL you want and click WRITE.
10. Return to ##3424#, Qualcomm usb setting, select MTP and Restart.
11. Enable your wifi and data.

I was unable to load any 56*** series PRL.
I was able to flash 56022 with the steps on post #2. Below is the link to all PRL.

Thanks for the info. I was able to flash the 503 PRL from S4GRU, but, the one I would prefer, 513, won't take. I may have to try again when the kids are in bed tonight. I think it's based on a 56xxx series PRL, so it might just flat out not work.

I'm glad to see that at least you were able to flash an older one. I tried various ones from the 56*** series and no luck. Hopefully you or someone else gets the ball from here. Im glad i was able to go back to an older prl. Now my phone is not switching towers every 2 secs.

Thanks! Unfortunately I had the same issue with 56xxx prls too...none of them would flash ..and that's the best one too!!

I goofed around with this a little this morning and had no luck with any Corporate PRLs. Just says process destroyed every time I hit write.

Will PRL change allow simo voice/data calls?
on my old phones i was able to do both phone call and data...
primarily when driving using google maps and getting an incoming call./text. now with spark i cant do this .
will updating a pRL... lets say to a tmobile tower allow me to do that again?

I have a much simpler option and can confirm this works just fine.
If you are rooted but do not have a custom recovery you can download the zip file in this link and extract HiddenMenu.apk located in the file under /system/app and manually push it into the /system/app folder on your phone. Then change the permissions to 0755
http://forum.xda-developers.com/showthread.php?p=54201284
(The file says deodexed but I'm running stock odexed rom and it worked just fine, also remember to back up original HiddenMenu.apk)
After that follow these steps
1. Extract TEST.prl from the PRL Zip that you want to flash
2. Place TEST.prl in the root of the /sdcard folder
(DO NOT put it in /mnt/extSdCard)
3. Turn off WIFI and Mobile Data on the phone
4. Dial ##DATA# (##3282#) and select "View"
5. Select PRL WRITE then hit the button labeled "PRL WRITE" (your device will reboot at this point)
6. Once your device turns back on, turn WIFI and Mobile Data back on.
7. Goto Settings -> About device -> Status and confirm "PRL version" matches the version you wished to flash
Hope this helps! please thank me if so:thumbup:

Was able to get 56022 as well. Can anybody recommend a paticular prl for best lte connectivity?

LTE is not affected by the PRL.

Ok, I just glanced over some of the links and thought the PRL determined what towers were available. So it only affects roaming?

PRL = preferred roaming list. Your phone will always scan for any of Spirit's LTE bands first. If it finds nothing on those three bands, it will then look for a Sprint CDMA (3G) signal. Failing to find one, it will then look to the PRL file to see what networks and at what speeds you (Sprint) are authorized to connect to and in what order. In a nutshell anyway.

Ahh, makes sense. Was just looking for any way to get better LTE connectivity and have the phone hold that connection.

This process works on OG5. Flashed 56025 PRL

MetroPCS PRL ICS issue

Is there a way to install a prl in zip format through recovery?
I installed ICS ROM http://forum.xda-developers.com/showthread.php?t=1544181 Its a great rom but I now have an outdated PRL file. Which means I'm now stuck in 1x land. I miss my 3G!
The ## codes do not work on this rom so QPST & CDMA are not an option. I am trying to find any way to update my PRL without needing to connect my EVO to my pc.
1. My 1st thought was an app that would update the prl. (But I can't find the one I had on my old GB ROM)
2. Flashable zip file containing the prl so I can install in recovery.
If anyone has an idea please let me know. BTW I have the latest PRL on my SD.
I found what I thought was a solution here.
http://www.goodandevo.net/2011/09/ho...tc-evo-4g.html
Its tedious but it worked for me. 3G goodness. (Or so I thought)
Basically downgrade to Sense rom, install PRL with QPST, then NANdroid back.
Now I am trying every prl I can find and my BIG issue is now if I use a prl that has 3G it wont use 1x at all. (If outside 3G range.) I end up w/ no data at all when it doesn't say 3G. leaving it on a prl that uses 1x I always have data, albeit slow.
FYI, I do not have 3G only checked on settings on QPST. Please someone offer me a route to take so I can have my 3G & 1x!
Had this same question and resorted to the above referenced method of going back to a version that can goto diag mode, like 4.67 and flash prl there and then flash back.

Sprint /Verizon/USCC S3/S4/S5 Note 2/Note 3 to Page Plus / Selectel Flashing Real 3G

I want this to be a thread dedicated to help others to flash the mentioned devices to Page Plus / Selectel / Next-G / Service in REAL 3G....
I have been flashing phones for a several years now as a hobby and want to pass on some of my knowledge and advice to others making this transition.
A few things I want to do when time allows as I work a full time job and have a family.. (Not to mention my Flashing Phone Hobby)
1. Keep a list of PRL's that work with Page Plus with no roaming symbol...
2. Maintain a summary of how to get into Diag Mode on all phones and methods to get your SPC/MSL on Sprint Phones......
3. Post useful Apks,, 16 Digit Passwords, and other instructions on flashing the phones.......
4. Maintain a Current List of Page plus Sids for Flashing..........
5. Make this a thread that people can come to and discuss issues etc....
Now I am not good at writing Guides and truthfully at this time have no desire to do so, but I will however try my best to help you along the way when my time is available. So please I ask do not flood my Inbox with request for a guide etc. (Post here so others can contribute and everyone can learn together)
One thing I have learned over the years of flashing devices is its better to think it through and work by trial and error so you can truly learn the skill of performing successful flashes.
(Please everyone keep it civil and make this a community effort to help each and everyone)
Current Status is that I can pull Keys/Passwords on Verizon S3 / S4 / S5 / Note 2 and 3, Sprint S2 / S3 /S4/S5 / Note 2 and 3, US Cellular S2 / S3 / S4/ S5 and Note 2 and 3 phones, Plus several other Phones and get REAL 3G with no donor on Page Plus / Selectel / Next-G....
(Again let me stress, please do not flood me with request to show you how to do this, as currently I will not post this information, I have my reasons and I hope you can respect that and use this thread for the other benefits you can get from it)
** Note: I did not include Verizon Prepaid or Straight Talk in this due to my beliefs that the cloning of esns/meids to obtain service is not LEGAL **

What is a PRL and what it does:
PRL=(Preferred Roaming List)
The PRL is a list of information that resides in the memory of some kinds of digital phones. It lists the radio frequencies the phone can use in various geographic areas.
The part of the list for each area is ordered by the bands the phone should try to use first. Therefore it's a kind of priority list for which towers the phone should use.
The PRL helps determine which home-network towers to use, and also which towers belonging to other networks to use in roaming situations (areas where the home network
has no coverage.) When roaming, the PRL may instruct the phone to use the network with the best roaming rate for the carrier, rather than the one with the strongest signal at the moment.
Since a PRL tells the phone "where" to search for a signal, as carrier networks change over time, an updated PRL may be required for a phone to "see" all of the coverage that it should,
both with the home network and for roaming.

Things Not To Do With A Flashed Phone
1. NO OTA Android Updates Period (You will break your flash)
2. No OTA Programming *228, *22890, *22800, *22801 or any other Variants
3. Some Rom's do not play well with Flashed Phones do your research before flashing.
4. Never do a RTN (Return to Network) Reset ##786# on a Flashed Device (Most definitely will break your flash)
5. Some Radios/Modems cause issues if you flash (If the phone is working leave it be)
6. Factory Reset ( I recommend not to do this also, some versions of Android phones it will break things period)
7. PRLS ..... aww my favorite, everyone thinks these are the answer to all their prayers
a. If the phone is working leave it be (my personal stance)
b. Some PRL's are not EVDO or have not been Modded and will break your 3G or throw the Roaming Symbol
c. I have posted many PRL's above that will work with 3G (Latest one I modded is 60007 for all carrier phones)
8. No Phone Number Change (You change your carrier assigned number, you must reflash)

Why Is My 3G Data Slow?
It's a complaint I hear everyday from people using flashed smartphones performed by them or another flashing provider...
Why are my speeds so slow and is it possible to improve the situation?
There are a variety of reasons why 3G data speeds may be less than stellar, and each one requires a different solution.
Before assuming there's a problem, though, make sure you understand the realistic capabilities of your service.
VERIZON/Page Plus/Selectel:
2G 1xRTT: 50-100kbps download and upload with bursts to 144 kbps
3G EVDO Rev-A: (shows up as "3G" on your phone): 600-1400kbps download with bursts to 3Mbps, 200-800kbps upload with bursts to 1.8Mbps
(Don't get to caught up in running speedtest as these can be very confusing and fool you at times into thinking you have a problem when actually
the way they test and the servers they use get congested also)
POTENTIAL PROBLEM #1: Weak signal
If you're too far away from the tower (or if there are a lot of obstructions/interference between you and the tower), your device won't be able
to pick up a strong signal and your performance will suffer.
Solution: Try other locations in your home or area you are in, some areas do not get great signal strength and this could be your issue.
POTENTIAL PROBLEM #2: Tower overcrowding (Network Congestion)
The bandwidth available from a cell tower is shared amongst all the users connecting to the tower. A cell tower can only provide so much bandwidth,
and the more users there are connecting to the tower, the slower everyone's speeds will be.
Is this YOUR problem? If you notice that your speeds tend to follow a pattern most days (for example, nice and fast late at night or early in the day but slower in the evening when everyone is home from work and school) and you've confirmed that the problem isn't signal-related (by testing your speeds at home and then again somewhere closer to the tower), you'll know your tower is simply being used by lots of other subscribers at the same time.
Solution: Unfortunately, there's nothing you can do about this (other than consider switching to a different provider who might have more capacity at their towers or isn't as oversold in your area).
POTENTIAL PROBLEM #3: Incorrectly Performed Flash
It's very common for flashed phones to have been done incorrectly.
Is this YOUR problem? This is very possibly the source of the problem if your flash was done incorrectly or you made changes to your setup recently.
Solution: You'll need to either troubleshoot the phone and or reflash the problem phone.
POTENTIAL PROBLEM #4: Tower issues
Providers periodically do maintenance or upgrade work on cell towers, which can disrupt service; other factors like severe weather occasionally damage cell towers and cause problems.
Is this YOUR problem? If your service suddenly degrades significantly and doesn't improve much during non-peak hours (which it would if the problem was overcrowding), and you've confirmed it's not a problem with your flash, the problem likely lies with the tower. The best way to confirm is to take your device several miles away where you'll be connecting to a different tower and test there — if everything works fine when connected to a different tower, you'll know something is amiss with your home tower.
Solution: Out of your control, bear with it until the provider finishes work and repairs.....
Potential Problem #5: Sprint and USSC Devices
I hate to say it but I have seen some Sprint/USSC phones have this issue, likely due to weaker radios and or hardware implemented in the device.
Is this YOUR problem? This is very possibly the source of the problem if your flash was done correctly and you verify that other devices on the network in the same location as yours get consistently better data speeds.
Solution: Verify flash is correct and that your connected at EVDO in settings and passwords have passed authentication. If so this most likely a Sprint/USSC device issue out of control by the user. Replace device with another Cellphone Carrier brand and most of the time problem will be solved. (I see this allot with some of the Samsung S3 Devices from Sprint/USSC, almost like certain lots had a weak radio for whatever reason)
In the end your speeds can be related to any or all of these issues, and a proper flash is key to performing at optimal speeds.
Sometimes as much as we hate to admit a professional flasher is needed to correct speed issues, you would not believe some of the poor flashes I see when I read preflashed phones everyday that so called professionals performed
Definitely keeping an eye on this thread! Thanks Viper for putting this together. As a current PP customer with a Sprint GS3, I'm interested in learning more.
I personally used DFS / QPST and a Fascinate to get mine working w/ 3G. A couple things I'd be interested in documenting / learning:
1) Updating the PRL on my GS3 (or other flashed Sprint phone). I currently have to activate my Fascinate, *22891, downloading PRL w/ DFS, loading it onto the GS3, then reactivating the GS3
2) The proper procedure to get AOSP roms to work 100% (MMS in particular) on flashed Sprint phones. I haven't tried yet, but I believe AOSP roms (vs TW) require some extra work to get full functionality.

#1 - Right now I'm just using the Verizon PRL that was on my Fascinate when I got the 3G keys from it - 53022. To get rid of the roaming icon, I loaded eri.xml onto my phone and changed the carrier name to Page Plus (actually I'm not sure if this actually removed the roaming triangle, but I rarely see it anymore.)
I know there has been a VZW PRL update since then - It's something like 53078 or 53096 now. I'm in the Chicago area so the exact PRL number probably depends on that.
I'd like to update the PRL on my (sprint) GS3, however the only way I know how to do it is by reactivating the Fascinate on my account to get the newest PRL, then saving it w/ DFS, then loading it onto my GS3 using DFS (then of course reactivating the GS3).
I was under the impression that *22891 to update PRL doesn't work on flashed Sprint phones, unless I"m mistaken?
***
As for #2, I did ask xda member alphahere about getting MMS working on AOSP roms, as he had mentioned in one of the PagePlus threads that he had AOSP fully working on his Sprint GS3. He gave me the following advice (which I haven't tested yet):
/system/etc/apns-conf.xml changed to the following to fix MMS
<?xml version="1.0" encoding="utf-8"?>
<apns version="7">
<apn carrier="Verizon"
mcc="310"
mnc="004"
apn="internet"
type="default,supl,mms"
mmsc="http://mms.vtext.com/servlets/mms"

I believe you can do the *22890 option 2 new PRL
the problem is that when it reboots it will have a roaming unless you go into dfs/cdma and change the Preffered Settings

Thats is what I do

Some US Cellular
Does anyone know what @Viper32 is referring to when he says that only "Some US Cellular" phones are able to have pulled keys/pass?
I only have one chance at buying a phone, if it ends up being a no-go I'm out the $$$ - is there a way to know if this process will work with a particular US Cellular phone?

Can you share your method of how to pull the aaa keys from the device?

Change from lte to h+ on aosp

How can I use only H+ on am soap ROM wit high flashing to a different tom then restoring to a backup...my phone hasn't been making backups correctly and I Dont want to try to restore a backup again till I want to flash another rom
The 3g APN that came with the ROM doesn't work..only the late one
Anyone? I'm desperate for a fix
I think is in Settings/more settings/mobile networks/network mode/ and choose your network. Those listed are LTE/GSM/WCDMA (Auto Mode), GSM only and WCDMA only. Hope this helps.

I am making the assumption you are on AT&T version of the SGS3 based off the fact that your profile shows you with AT&T. If this is the case before you select from network modes, you need to select "network operator". This will take several minutes to find them all and give you a selection. Once it finally populates, you can choose your carrier. I get 3 AT&T options on my phone so I just choose the first one. Selecting anything other than the AT&T network may not work. Once you have done this you should be able to make the network selection stick. This will only last until you reboot and you will need to redo the process over again. I do not know if switching Airplane mode on and off will cause the need to redo it but you can test it out to check.
Thanks! It works! Thanks for your help! i will only have to use this till I can make good backups again

No Signal / No Network

Hello, I am new here but have intermediate experience with devices.
Alright time to throw everyone for a loop lol, hopefully someone can help me out.
Here is my problem:
My phone is not connected to a network.
Here is what I have:
Samsung Galaxy S III with Metro PCS (NOT rooted, and with latest PRL and software updates)
What happened:
I woke up yesterday to find my phone not on Metros network, and not on a partner network. My 4G still works though, I can access internet but just can not call/txt or receive either.
In Settings > About Device > Status, here are some of the satus'...
Network: Searching for Service
Signal Strength: -93dBm 47asu
Mobile Network Type: LTE:14
Service State: Out of Service
Roaming: Not Roaming
My Phone Number: Unknown
Min: Unknown
PRL Version: 0
Things I've Done So Far:
Contacted Metro through phone support and Facebook support, neither could help fix the problem.
Took my phone into a Metro store and they wont honor a repair since my screen has a hairline crack in the screen. (which I will also say, they noted that already on my account...)
I've already went to *#22745927 and enabled the hidden menu multiple times (cause it disables with each restart) and I've went to **772 to view my MDN and MSID (MIN) and the MDN shows nothing and MSID has a 10 digit number (that's not the right number for my account), so I tried to edit them to the numbers that I know are correct and after I hit done, the phone restarts but then when it comes back on, nothings changed, and when viewing **772 again, the numbers don't save in the fields.
I know *#197328640# lets you access the service menu, but I don't really feel like touching any of that and making things worse (unless someone knows how to fix this issue through the service menu then ill do it)
Now that my long winded speech is done, its your turn to try and solve this dilemma and help me out please
I hope this is the right section to post in, sorry if it is not.
Thanks in advance to any help ^^ if anyone's got any other questions, ill try to answer them best as I can.
With your Device not being Rooted, the options are limited. Also a bit more clarification. You say you have no Signal / Network. But yet you also state you have 4G, and can access the Internet. That is a bit contradictory. It sounds like you may need to have the Device Flashed to Metro again, as something may have gone wonky.
Try to dial *228 then call and see if it will go through an activation process of some kind. If it does, let it go through until successful then reboot your phone.
Sent from my SPH-L710 using Tapatalk 4
Dial code ##72786# is supposed to reactivate you phone. That might fix your problem. Alternatively, you can try writing a PRL that you know works with Metro.
You can dial ##DATA# and go to View. Some ROMs (even stock ROMs) have a "Write PRL" option. If your ROM does not have that, you can try the HiddenMenu.apk trick and see if that fixes it for you.
If PRL is 0, then it is not scanning for sites. LTE is handled by a different function, not PRL. Voice/Text rely on PRL to function. Hopefully the PRL fix helps you.
I have attached hiddenmenu.apk that has PRL Write enabler. Just download and install as normal app. If it does not work and breaks your dialer, simply reboot. The HiddenMenu is only temporary until you reboot, it reverts back to hiddenmenu under /system.

Yea I'm not totally sure why I can access 4G data but not the network.
I brought my phone into a Corporate Metro store and they told me it might be a faulty CDMA antenna but I don't think an antenna issue would put my PRL to 0 and not show my phone number or MIN.

I tried to use the dialer with Wifi on, with 4G Data on. Even tried to use Metros "Joyn" service which lets you make calls and texts over data connection but the issue is, I did a factory reset already and by doing that it wiped the Joyn data from my phone. Now when I go to start "Joyn" up, it says it needs to be able to connect to Metros Network for the first time set-up so I cant do that since I cant connect to the mobile network (CDMA).
I still need to try what Ascertion said.

Yea I went there, I asked how to install it since I don't see a .apk file anywhere and they said the APK is the download.
Usually you can download a file with the extension .apk then install it from your phone easily but since there is no file in that download with the file extension ".apk" then I don't see how I can install...
Quick update:
Got that download to change to .APK by simply renaming the file extension.
But after I loaded it to my phone and tried running it, it greeted me with an "Application Not Installed" message.

APN won't stick

I have unlocked s6 and APN won't stick. When put into network mode automatic I get to input APN and it works until I let phone turn off screen or I manually hit power button. When I get back into phone the APN setting I input, for t-mobile, are gone. There are Sprint APN listed but I can't choose nor add or delete any. If I choose LTE GSM auto prl through one of the service menu's I am able to again choose APN and input what I want but at sleep and rewake the phone goes back to not listing the APN and having greyed out sprint APN. Phone works but have data issues here and there and sometimes have to reboot to get lte to stick. Lock screen sometimes shows T-mobile as carrier but usually shows Sprint. I can still make calls and use LTE data on my t-mobile sim when it says Sprint as carrier but I think my data and mms issues would be fixed if I could get the dang APN to stick. Any ideas? Different rom? I'm on 5.1.1 OJ7

This is a really old thread, but since I've been struggling with this issue for several months, I think this is the place for a reply.
There are several problems with a "sprint" unlocked S6, but the most annoying (other than hands free activation) is the APN settings going back to default and being "locked" until you reboot the phone. When in this "locked" state - you will not be able to receive MMS messages.
I have found that deleting (or simply renaming) the customer.xml (/system/csc/customer.xml) stops the resetting of the APN - and interestingly opens up the additional configurations under Mobile Networks -> Network Mode to choose GSM/WCDMA/LTE.
After fixing this and fixing hands free activation (https://forum.xda-developers.com/sprint-galaxy-s6/help/hands-free-activation-t3199214) the phone now performs VERY well on T-Mobile, just like it belongs there
I just checked my device on 7.0 Nougat and I can't find that file (there is no folder in root>system called "csc"). Any idea how I can fix this?

You may not be allowed to view certain system files for some reason. I believe you have to be rooted to delete them. You could also try the system update first if you are stock. But probably best bet either way would be to start with clean install of whatever ROM you use or the stock ROM from TWRP. I've been able to delete the files from skyhigh and Rick Wardenberg's ROM.

Edit: I recommend es root explorer to do the dirty work.
if it's not too late
First you need your msl code I can help if not.then use data daily code or an app idonee don't get a fake I found on code after you do that you just need to change mms and apn setting see screenshot.i have 920p on 7.0 stock rooted running on t-mobile lte get mms everything
