LG L55C Want to try new PRL File.. How?? - Android Q&A, Help & Troubleshooting

Ive rooted my LG Optimus Q L55C which is through straight talk.. They say its powered by sprint towers.. But the problem is that i have horrible reception in my apartment and area.. Ive recified this in the past (On other phones) by changing the PRL file.. and want to try it out on this phone
But i cannot find anything on the internet describing how to do it.. I've found several posts related to a program called QPST which i've tried but for some reason my computer or the QPST program is not recognizing the phone correctly.. I've installed the LG usb drivers and everything but i cant get it to connect..
I've also found numerous posts saying to punch ##775# into the dialpad, which doesnt work either.. Ive tried other codes i've found and some work and some dont but nothing leading to changing the PRL file..
Does anyone know how to accomplish this with the L55C from straight talk?
Any help would greatly be appreciated..
Thanks

Nothing yet huh? lol (bump)

[Q] Activating Optimus V on Sprint's network

Hi,
I'm a long-time lurker, this is my first post. I've searched and searched for this topic, but I dont think that it's something many people are trying to do. I hope I'm posting into the right forum. I'm pretty new to any sort of Android development, so I apologize in advance for any
I have a Virgin Optimus V that I have moved over to Sprint.
The phone has been activated on Sprint and I'm capable of making phone calls and SMS, but I can't get the device to connect to Sprint's 3G data.
I figured that by installing a Sprint ROM, I would get the Sprint modem.bin and be able to "Update Profile" to provision the phone to Sprint and get data working.
no such luck. I have flashed over to the Thunder rom for Optimus S and I'm in the same place. I can call and text, but still no Data. When I try and "Update Profile" it fails and immediately restarts the device.
Any ideas as to what is left on the device that would prevent it from connecting to Sprint data?
Bump... I would also like to know the answer to this since I've been thinking of doing this as well. How were you able to get the phone on Sprint's network in the first place?
I'm operating on an MVNO Wholesale network. If I were trying to activate this device on the normal Sprint network, I could understand the problem, as you can't switch ESNs back and forth. Given my scenario, I really can't understand what could possibly be limiting me from doing this. . .
Since my OP, I've flashed the Sprint PRL to the phone with qpst. I'm running ThundeROM V1.8. I turn on Airplane Mode, then turn it off and I see the 3G data icon for just a minute and then it disappears. When I try to update the Profile now, it trys and trys and eventually times out. . . but it no longer restarts the device after failing.
I'm also prompted to install system updates. . . which seems to indicate some kind of data connection is active?
I've been trying to change the APN settings through ##DATA#, but after I make a change to the Data Profile Username (from the @mdata.vombl.com to @sprintpcs.com) the phone restarts and the OLD values are still in the phone?
I'm thinking that the ##DATA# settings are incorrect? But how can I get the changes I make to "Stick" ? Since all of these settings were reset the last time I wiped the phone, I'd imagine that the AAA Password will also need to be set?
I was under the impression that the AAA Password (and most of the ##DATA# settings would configure themselves once I program in the MSID and MDN?)
Any help or shoves in the right direction would be appreciated.
I wish I was more knowledgeable in this area to be able to help...
Sorry! I didn't mean to dismiss your issue if this is what you're trying to do, I'm interested in this also. . . but I think Sprint keeps Virgin ESN's distinctly seperate from Sprint ESN's, the classic problem with a lot of other devices people would love to use on Sprint. I just lost my personal Sprint phone and I need a new one, it would be great if I could flash this V over to it.
I'm pretty new to this stuff too . . . I think that someone with more knowledge could likely help both of us =)
Any update? I was think about doing the same thing.
Bump
I really doubt you can get Sprint to provision the phone because I'm sure they would want to keep the meids/esns separate.
I have the same issue but have repaired my ESN. I have tried copying the actual NV items directly to the memory locations but on reboot the Virgin info repopulates. I posted in the the general section before I found this thread. I got no response in my thread yet. If mods want to move my thread into this one, I am fine with that.
If I find out anymore info, I will post in here.
I'm sure you're having an issue with the AAA and HA passwords for 3G. Unlike other phones, the Optimus V is not well-mapped (yet) for this info. A lot of people are having 3G issues when the phone updates, say from 2.1 to 2.2. VM customer support is terrible, they usually say to just pull the battery. Apparently the AAA and HA do not come back under these circumstances. If there was a way to find the HA and AAA PW like you can for others, people could fix this problem themselves.
Sorry this is no help, but I think that is the specific problem you're having based on your OP.

[Q] make phone force-roam

So I know there are a million threads about this...on non-thunderbolt forums, but still, can anyone tell me if there is a way that I can force the phone to roam on the 'Extended Network'. Hopping between networks is killin my battery.
A friend of mine with the same phone tried that app to no avail, and he's looking for a solution too.
I am interested in this as well. I need to figure out a way to force roam on my HTC Thunderbolt since I am unable to manually update the PRL. If anyone has figured out a way to do this, I would appreciate the help!

vs985 on ting?

So I have found some people saying yes and some saying no about being able to get data... I've connected to tings service a couple times but never been able to get data. I've tried custom and stick rooms. I've tried channeling the apn.
I wouldn't say I'm a complete noob but definitely a novice so it's likely i've done something wrong. Anyhelp would be great.
Thanks in advanced.
BTW I'm trying to connect to gsm

Galaxy s3 no network internet please help!!!!!

Ok so a little background on whats going on.My phone is a SCH-R530X.. (Note the X. Its the generic version) CDMA on MobileNation... I was in the Service Mode on my galaxy and layed it down on the table. My son picks it up and starts pushing things on it. When I got back I had no service what so ever. It wouldn't connect to a tower at all. After going through the service menu tring to figure out what he changed with no luck, I flashed using Kies. No luck with that. I did some research on it and tried a few things. Finely after failed attempts, I ran across the ##786# that is a return feature that basically dumped some things and restored it to factory. After doing that I finely got service back but no internet or 3g icon that is usually there.. I have tried restoring it, doing *228 activation with no luck. Something got messed up and will not let my internet... I'm good when it comes to doing things like codes settings and flashing so i know how to do that. I just dont know at this point what to do and im asking for help here in hopes to get it back to normal. I also forgot to mention that i took it to the phone company and the 2 people i talk to there didn't know nothing when it come to it. The first time i took it up there it was not working at all and he said he tried everything and that hes sure it was service bricked. Then after i did the ##786# thing i took it back to him to see if they could get the internet going. He was like, I wish i knew what you did to fix that part of the service cause i tried everything and bla bla...... The only thing they know how to do is activate them and dont know crap when it comes to troubleshooting.... Anyway please help.....
There use to be firmware here for it but i see its gone from this site. If i could try maybe reflashing as much as i could i would but i cant find the right firmware for the phone.
Check apns
