I currently have a sprint HTC Vogue and I am trying to flash the Verizon PRL onto it so I can use it on the PagePlus network. Everything I have seen says to dial #775#, but when I do that, my phone just tries to dial the number. I was using NSFAN's rom, and I even tried other roms and it does the same thing. Any help with this will be greatly appreciated.

Which rom are you using now? If you are flashing a custom rom, more than likely you have a folder called "Phone Codes" somewhere in the Start menu. In there, you will have one that is called PRL. You have to have the MSL code to change this value though.
Get the PRL that you need and dump it somewhere in your phone. When you open the PRL program in phone codes (and you enter the MSL code), simply tap and hold where it says the PRL version and click on "Edit" (or whatever option you get), look for yours, and presto! Save, exit (you will be asked to soft reset).
Hope this helps.
Thanks. I have the MSL. I am flashing the official Sprint WM6.1 rom right now out of desperation, but I can put whatever on there. Do I need a custom rom in order to use the "phone codes" folder?

To get it in folder format, yes. But if you are going for a stock rom, then simply use the codes and you'll be in good shape.
I want to change PRL in my HTC.
I can access to ##775#.
But I can't find anywhere to PRL file in my phone.
I want to change PRL by myself.
Sometimes, I can use my phone.
But most of times, it shown searching and if i got signal, it shown antenna only. So how should I do? Please help me.

Have you tried to use the *228 (or whatever Sprint's equivalent is)? It should automatically provision your device.

When I flashed my Sprint Vogue for Verizon usage... I first had to flash the newest stock Verizon ROM (You can find it on NuAngel's goodies page at the bottom! Yes the radio change one!), then flash a Verizon PRL to the phone. Nu told me I would have to reunlock the phone afterward, but I didn't need to.
I was then able to dial *228 and program the phone! After the phone was programed, I could finally flash ROMs onto it and still have working service. This phone didn't like NuVogue 5 (even though most of NuVogue's development was done on this phone.. wtf). Nu cooked a Verizon specific NuVogue 5 and it worked a bit better, but I remained on stock until I was able to cook my own build (still working on, I have plans on posting it after conferring with Nu and stealingz some of his ideas).
I can update the phone roaming via *228 only with the stock Verizon ROM (does not work on ANY cooked ROMS I have tried!!), but because the phone still has a Sprint PRI (feel free to message me instructions on switching to a Verizon PRI, cause I haven't found them yet), I get the roaming triangle. I used the latest moded PRL found in this thread here (51831) and I've been great ever since.
I try to avoid Carrier generic ROMs (or cooking my in development "XevRev" [tentative name] as generic) since they reflash the PRL, which is just a pain in the butt imo. I plan on trying NuVogue 6 when Nu and I go to hang at his place sometime this coming week, I want to see if its improved over the previous release on this phone. Can't explain why the release ran so waked out in v5 on this phone..... anyway...).

Well, I was trying a few roms a few days ago and later i decided to go back to stock, I accidentally let the customizations run, and it went back to verizon, but i flashed the 0068 (or something like that) PRL file to the phone using EPST, after that I dialed *228 and updated the PRL to 02004 (latest MetroPCS PRL file), but i still cant use it, (i realized just 5 mins ago, 2 days after prl flashing -_-) I called the customer support just now and they said they just reset the device and I should shut it down and restart it, so anyways my question is:
I can't use my phone, I cant call, text or use web, and no one can call me, it says service not activated when i try to connect to the internet, and I cant use my voice mail either(LA 01 message something error) What should I Do?
Thanks guys.

The only thing that comes to mind would be for the VZW customizations to actually modify more than just PRL (but mess with other EPST settings as well). Just to confirm, did you have your phone working on Metro before this?
yes, it was working perfectly, even the mms and web were working :|
EDIT: I can call *611 and *228, oh wait i think i said that in the first post...

If you had 2.31 installed, the device should still be unlocked. Try running a hard reset/flashing another rom and see if that helps. I have a feeling that you will need to go into EPST and play with your MSID and MIN values and a few other things as well.

I hard reset on stock rom and didn't let the customizations run, then flashed 3.42.30 (alltell rom i think) and with out resetting the device I just put the nfsfan's rom in the sd card and flashed that, it still didn't help, can someone give me the settings for the PST.

3.42.30 is a radio and not an actual rom. My guess would be that, unless you have them stored somewhere else, you will need to call Metro and ask them to help you re-program the phone. Couple of pointers:
a. Don't tell them that you have a Vogue (let alone a Vogue running 6.5) since they have little/no experience with WM devices.
b. Using BAFMSL, get your MSL from your device (you will need this to unlock and edit the EPST parameters. My guess is that you read the ESN to the Metro rep, who calculated an MSL, which of course did not work (here I am assuming that the ESN on your device has been cloned from another phone)).
c. What you want to get out of the rep are the numeric parameters for:
MIN (normally your phone number)
MSID
HomeSID
Don't assume that he/she will be able to guide you through the editing process because they simply won't know how. A simple "yes, go on" every time they tell you to change something will suffice. Just make sure you write the numbers down in a piece of paper.
Do this and get your numbers. If they are any different from the ones that are currently loaded, then your issue will be solved.
Just thought of one other thing. You said you went back to stock Verizon. Which radio did you have before that? And what radio did the Verizon rom take it to?
well, I had it metroflashed, and i can't do it again as i don't have any money now (only 15 years old xD), it has original ESN, does this change anything?
and btw, i can edit the epst, (the code is six 0s) or i may be wrong )

Nah, Metroflash via Houdinisoft does two things:
1. It will add the ESN into Metro's database and will link it to your account.
2. It may provision your phone. I say may because I have seen, more often than not, that Houdini fails to provision any device that runs WM.
Asking you again about the radios. What radio did you have prior to flashing to Verizon stock and what did the stock flash the radio to?

Yes, I was asking because I was afraid that you went below 3.xx.xx on the radio as this has been known to cause issues, including leaving phones completely useless.
Did you get the parameters from Metro as I suggested earlier?
well I got rid of the phone, as the representatives were not helping me at all (I talked to 5) so I am just going to buy a LG rumor touch (virgin mobile) and my other choice is Tmobile G1 but can I get it without a data plan?

Only if you buy it without contract (the G1, that is). Sorry that you couldn't get it to work. I am sure that it was only a matter of re-programming the device.
Are there any fellow Sprint users on the MXPE? If you are, are you running an AOSP ROM? Have you ever gotten data and voice roaming working on AOSP? If so, how'd you do it?
Yes, I've had data working on the orion rom (which I believe is cm13 based). Check your apn's, the one containing n5......something.or.other is the appropriate one IIRC.
Mobile networks should be cdma/lte.
Network data and voice is just fine for me. It's all roaming that's messed up. Will check apn's next time I flash.

I must be blind, but where do we find the APN settings on the phone?
^^It's a byproduct of "stock" software. APN's access is readily available in aosp/non stock roms.
The function is still there in the stock rom, but requires an extra step or two to get at it.
If you use a third party launcher such as nova, you can add it under activities. Long press a blank area on the home screen, select widgets, then swipe to the left on the top most row, select activities. Scroll down and open the settings entry then look for APN.
Or, use this - https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher&hl=en
I'm on Sprint with STOCK/LOCKED/UNROOTED and this phone flat out refuses to roam all over the US. Specifically what APNs should be in the STOCK list (I used Nova to access APNs) and they look to be there.
^^I don't think the apn has anything to do with roaming. Have you checked your roaming options under the main android settings?
Are you on a plan that provides roaming? Roaming properly enabled on your account? Updated the prl?

I drive semi truck, my usual run is Wisconsin to Washington state and back. My phone, for the most part, will switch into roaming using TruPure. Two runs ago my phone wouldn't roam at all. I tried toggling data, updating PRL and the device config, eventually doing a clean flash, and still had no roaming. Eventually I ran the stock restore tool, flashed the modem separately, and did *#*#72786#*#* in the dialer. I'm back to roaming on a stock based ROM again. I haven't tried an AOSP rom since posting my question a few days ago.

^^Did you post about this in the rom thread? I'd guess one of the removed services is somehow affecting roaming.
I wanted to do a bit more trouble shooting first. Before my next to Washington, my plan was to flash AOSP and see if roaming was working again. I forgot to note, after confirming roaming was working on the stock ROM again, TruPure was flashed and was roaming properly too. My thoughts were that somehow Sprint provisioning got screwed up or a flash somehow messed up the modem.
When you flashed truepure again, what type of reset did you do (if any)?
Sprint's provisioning system is poop. Their system is a 2 part authentication. Your voice/text is tied to the device meid (not imei), data is tied to the sim card. This seems quite @ssbackward to me, considering verizon, tmo, att all associated your number with the sim card. While the device still transmits its imei during registration, no user intervention is needed when switching device. With sprint you need to log into the account and update the device too.
It seems each time you do a clean flash (wipe userdata), the software attempt to perform the 'handsfree' activation (or its equivalent on the moto x). If you perform a factory reset from within android, a number of carrier parameters get erased. If you a factory reset from twrp, they get retained.
I'm also on sprint but through ringplus, so no roaming included.
After running the http://forum.xda-developers.com/showthread.php?t=3199905
[WINDOWS TOOL][5.1.1]Moto X Style/Pure Edition "Restore-To-Stock-Tool" , flashing the modem separately, and doing the dialer codes, all was good with roaming. Roaming again worked with TruPure. Nothing special was needed. After restoring stock and reflashing TWRP, I just flashed TruPure like any other rom. No special steps were needed.

Sorry for the long delay, been all over the place.
Yes plan provides roaming, and is enabled. PRL updated. I verified with Sprint customer care that the account is provisioned with no errors so I should be good to go on the Sprint side.
Im going to try what Misfit0313 did, restore to stock and flash modem. I'm assuming the return to stock takes it back to Lollipop so I'll get the MM OTA. Are you able to flash a modem on MM? Maybe the Modem side got corrupted somehow on my stock phone when it upgraded to MM right out of the box.
Buried in the Restore to Stock tool thread, there are directions to flash the modem separately via ADB. For some reason, the tool broke WiFi, necessitating the need for the modem reflash.
I just took the OTA to come from LP to MM

I flashed this fix on a clean install and AOSP roaming is working.
So roaming is controlled by the apn?? Interesting. Didn't realize that was the case.
Are you the same misfit on the freenode network/evo4g lte days?

Dude, yep its me. I don't stop in there too much anymore. Always bs going on in my life. Hobbit problems.
I tried to change APN settings as you suggested in AICP rom, but I kept getting a message like 'user doesn't have sufficient privileges to change settings'. That's why i gave that old ass fix a try. Reported in AICP thread. Went to south TX this week and I have no issues to report with voice or data roaming on AICP.
Still have the Infinity or did you move onto something badder?

i can't set APNs or even make calls/texts on AOSP ROMs like Dirty Unicorn and PureNexis with Sprint...Flashing this zip fixed that for you?
Edit: Meh...just tried clean flashing PureNexis with the sprint.zip fix and still cant make calls or set APN's
My question: Is roaming working on stock based roms for you?
Stock roaming wasn't working for me, and Sprint insisted it wasn't at their end. After doing all the steps I mentioned previously, stock roaming finally was a go. I still had to flash the sprint.zip on a clean install to get AOSP roaming working. Without roaming on stock, there's no way roaming will work on any other ROM.
Phone Information
Phone Number: Last owner shows up, want this cleared
Android Version: 7.0
Build Number: NRD90M
Software Version: LS997ZV6
Security software: MDF V2.0 release 4
OEM Unlock (On)
USB Debugging (On)
PROBLEM: A sprint V20 was brought to me to have the carrier swapped from [Sprint] to [Cricket]. So far sounds easy right? Read below...
Please Review the following of my step by step :
ESN IS LISTED AS CLEAR ON SWAPPA, please note that means this device "should" not have issues (first thing I checked)
Under APN settings there is no way to +add APN as there is with every other phone I have touched. Is this because it was a lease?
I considered perhaps rooting the phone, throwing on a custom ROM, and therefore hopefully having that added. Looks like bootloader is locked.
Of course, I am 1 security patch too late, DIRTYSANTA will NOT work on my firmware.
Searched everywhere, seems as though you CAN NOT roll this back.
Next I looked at using Chimera Tool to roll back the firmware. I cannot seem to find a ZV5 firmware file.
Next I looked at using chimera for IMEI repair. I figured if I change the IMEI just long enough to modify the APN settings then revert it back, I would be golden. Chimera gave me an error of not having access to the ports. I tried to dial in the following codes to enable port check but none have access to the "hidden menu". 277634#*#, 3845#*997#, *#546368#*997#. I tried to factory reset the phone, no luck.
I was able to use ##DIAG# (##3424#) and enable DIAGNOSTIC mode, yet this seemed to do nothing about ports.
I was able to enter ##DEBUG (##33284#) but there is no ability to ediit in here. Although at one point in time I was at a screen asking for an SVC code, no idea how to get back there though.
Tried to do a "fix" on Chimera, which is the same as refurbish on LG Up (I need the phone in factory condition), but apparently this device does not support refurbish mode. So flashing software is not wiping anything.
I cant seem to boot it into recovery, for god knows why.
QUESTIONS I HAVE
How do I completely wipe the phone of all user data?
How do I open these ports since the codes provided bring up no menu?
Since sprint is the only one recognizing the bad ESN, is this device able to even swap carriers?
What reason would APN not have an ability to edit or modify?
What additional tactics can I use to get my goal accomplished?
Hopefully we can brainstorm together
Please refer to this thread, it should work and do what you need to withthat apk. I belive its under IOT menu then under lte and put it in lab mode and turn on all the bands plus adding APN .. Im not to sure but ask the OP im sure he is way more helpful... asfar as adding the apn without this you need root to be able to do this and for nonroot i believe you must use ADb commands to tgecdevice and add them from there. there is threads oithere....
https://forum.xda-developers.com/v20/help/lg-v20-cdma-to-lte-gsm-switch-via-t3602409
if the esn is now listed as unpaid, or lost /stolen cricket will not be able to add the esn to their system either. its a nation wide list that blacklist's the device.
Unfortunately changing the apns etc wont fix this.
ZV6 currently does not have a way to be rolled back, so there is 0 root/custom options.
APNS have been blocked by sprint for some time now and using some root methods they can be unlocked, in your case you wont be able to access them due to being unable to root.
Tools like CDMA WORKSHOP, QPST, QXDMA, etc may be able to write the apns and such you would need, if you could get the msl for the device, but if it is no longer active, and the device has a "bad esn" then you wont be getting that from the carrier. I dont believe youll be able to access the nv items etc without it and probably not going to be easy to locate the msl.
##diag# is how youll talk to the device on cdma workshop etc, youll need to go to your installed devices and change its com port to a port thats free and remember the port as the tools need you to select that port, but again they wont work for you without the msl anyways.
so in a nutshell, it looks like your best option is to sell the phone as parts only, or if recently purchased on swappa and it was listed good esn and its not then file a report at-least to make swappa aware.

Sent from my HTC 0PJA2 using XDA Labs
So I have been using MetroPCS on my Moto G5 Plus since I got it. Well today I went and activated my device with the Sprint network... It wasn't working when I left the store, and I told the rep how it was modified (using RessurectionRemix 5.8.4 Final), that I would work on setting it up.
Well, so far no success in activating it... Have tried changing network mode to CDMA/LTE and messing around with dialer codes, still can't get anything besides "emergency calls only."
Anyone have experienced getting this phone activated with Sprint?
Note: they did tell me they didn't have the exact, or "recommended," SIM card for my device, and that it was a secondary option they used in the system(?).

I am using that SIM, got it working when I reflashed stock. Did not work again when I restored RR, at least fully, as I was able to get data to work minus SMS/calls.
I'm on Sprint. No issues with any Roms.
You need to be on a stock build for the initial setup, because the custom roms remove all of the PRL stuff. Once it is setup once, flash whatever you want.

It doesn't stick after I flash a custom ROM
That's really odd. I don't have that problem...
Make sure you have APNs on the custom rom. I saw a problem a while back that the custom rom didn't keep the APN for some reason, and I had to put it in manually. Different device, but same problem.

Can you tell me what your APN info is? I have data and calling working now, but no LTE option (see screenshot)
I have mine set to global.
I had this same issue with my s6, and I ended up having to factory reset the phone, and redoing the PRL update, and the option finally came back.
Just to follow up, I was able to get full LTE and calls to work by flashing stock ROM, updating PRL, and by then it was provisioned on the Sprint network.
As it stands now, if I reinsert my MetroPCS sim card, it is provisioned for MetroPCS no problem, but I do have to reflash stock again each time I want to provision for Sprint.
So thats how I am going to run things for now, by making backups and getting it provisioned using stock before restoring.
this worked for me

theres an ap on the play store called apn backup and restore. install it on stock rom . b4 using it u need to go in system/apps and move the apk to system/priv/apps once moved changed permissions to r-w-r-r. after that a quick reboot and open app change setting to disable ics check and do a backup . once finished do the same thing on new rom and mine works flawlessly. im on boost which is also on sprint network. good luck hope this helps
