Hey everyone,
I want to share my experience with VZW's PRL since there seems to be so many differing opinions as to what happens when you dial *22899 and whether you will get back to a 4G PRL. I have seen several threads across different forums discussing the dangers of doing *22899, being stuck on a 3G PRL, killing your SIM, and the different methods to get back to a 4G PRL. First off, none of the methods work, at least not for me. I have pulled battery and SIM for over 1 minute, booted w/o SIM then rebooted with SIM in, reflashed bootloader, radios, and ROM...all to no avail. The only way to get back onto a 4G PRL without changing your SIM is to wait for Verizon to push a new one. Verizon just pushed a new 4G PRL, 15192, and my phone is currently on it. I was on 52985 for about the past 3 months, so I'm assuming they push one out every quarter. Now this is only with the GNex as I don't know how any other phones behave, but I can't imagine they are that much different when it comes to PRLs and Verizon's network.
Secondly, you won't kill your SIM by *22899ing your GNex. I highly doubt I have a super SIM and I have *22899ed my GNex more times than I can count, sometimes multiple times a day, thinking that it would improve my signal and because I thought the 15*** PRL was an old PRL and 5**** was newer. I hope this helps someone that *22899ed their phone and wasn't sure how to get back on a 4G PRL.
I disagree about the only way to get back onto 4G is to just wait for Verizon to push a new PRL. CALL VERIZON. If you're in a fringe LTE area and your phone is having data issues, they'll probably give you a PRL that will keep your phone from looking for LTE, or will get you back on LTE if need be.
My original GNex went to pot with hardware issues in the radios. The 2nd or 3rd thing Verizon Tech Support did was toss out some PRL's for me to try.

You're right. I'll rephrase and say the only way, without having to contact Verizon in one form or another, is to wait. I just want to save people the headache of trying all the fixes and thinking that they did something wrong when it doesn't work. I tried everything multiple times thinking I didn't pull the SIM long enough or I missed a step. I didn't contact Verizon b/c I didn't want to put the phone back to stock and relock the bootloader if they needed to see the phone.

Our local tower was Alltel before the merger. We've since switched to a Verizon plan and phones. Seems they just can't get the local tower straightened out. Alltel phones hit it fine. Tower completely ignores Verizon phones - even though Verizon has told me the tower is updated. They are constantly trying to fix the problem.
So, their latest solution is to push me a custom PRL. They said I should get it within 24 hrs and then never, ever, ever, do a *228 again. Like many of you, I tinker with the phone and cold resets happen every couple of months. Telling me to never do *228 again just doesnt work for me.
So, any ideas as to how I can backup and restore my custom RPL after they push it me? Phone is a TP2.
Thanks
They're just pushing you the hybrid PRL. You can download it now if you want from this website:
http://corolada.com/prl/
It's under the Verizon>Hybrid section. To install it, just copy the file to your phone, do a ##PRL and use the application. It's pretty painless.
Had a look at my PRL number today.. Seems they sent me 65048, which is not on the list at http://corolada.com/prl/ .
Is this a file in \Windows I can find?
Thanks
I'm not aware of one, but that doesn't mean it's not on the phone somewhere. I'm also on an Alltel plan with a Verizon TP2. I was having quite a bit of troubles with signal bouncing between 1x and RevA. I finally put one of the older Alltel PRLs that allowed Sprint EVDO roaming on the phone and things picked up nicely.
You might want to try the 40042 Alltel one if you're still having problems.
txyaloo: Earlier you said to copy the PRL to the phone and do ##PRL. For this case, is there a specific directory/folder?
Btw, thanks for the help.

No specific directory. I either put it on my storage card in a stored PRL folder or in My Documents if I don't have the card installed.
I like keeping an Alltel with Spring roaming, the Verizon hybrid, and a regular Verizon PRL on hand in case I'm in an area with really poor coverage so I can switch on the fly.
A few weeks ago my evos data became ridiculously slow. I was the latest stable cm6 (6.1.2 iirc) and it was out of nowhere since I did not install any new apps or make any changes. I did a nandroid back to when I first rooted and I still had no 3g (wifi, bluetooth, wimax, 1x all work).
The tech I talked to at Sprint had me try updating everything and even a factory reset (which I already tried before calling). I have Best Buys phone insurance (never again. Sprints is much better after having to use both at one point or another) so I took it to best buy and when I get my phone home the data and phone are slow. After a few days I notice in ##debug# evdo engineering has <failed> on everything and I was running 3.26.xx.x I just ran the ruu to the latest 3.70 and it is snappy again but still no 3g.
Once I get time I am going to take it to the sprint repair center but I am curious if anyone else has had this problem. A search on here and Google doesn't come up with anything.

Have you tried updating your profile? Also, are your radio/baseband, PRI, NV & WiMax files updated to the latest versions? You can check it by going to Menu-Settings-About Phone-Software Information. The NV will not be listed, by the way.
Yes, everything is the latest. I even tried the port and proxy reset to 0 and 0.0.0.0 respectively method with no change.
It seems like my radio just doesn't work on 3g anymore. I hope to get to the sprint service center before the weekend.

I hear ya. Hopefully, they'll provide you with a new EVO instead of a refurbished one.
Call sprint's advanced tech support.
877-809-6696 ats advanced tech supp
Ask them to do a full profile reset or update. They ask you to power the phone off for a few min (they even asked me to pull the battery, but I didn't see a need for that). Then when it reboots, it will do the ota provisioning, which should correct things.

They did that as well. The tech said it was basically like a new line.
It is odd because every other thread I see online has had it fixed by one of the common methods or by calling sprint.
I have a tux fitting tomorrow for my brothers wedding and the sprint service center isn't too far from that so I should be able to get it checked out then.
It may be Sprint and their network. A lot of people have been stating that they are either getting really fast speeds or really slow speeds. If I understood everything correctly I think that Sprint is going through several updates for a while to be more competitive and provide better service. It may not be your phone. If you have any friends with the same phone then does a speed test to the same server side by side and see if that is different. If the results are the same it is the network, but if the other phone is faster then it is your phone that is having the problems.

My friends evo is perfect right next to mine in san jose to sacramento. I have no 3g anywhere I have been lately (Monterey all the way to South Lake Tahoe).
I was having the Same Issue with my wife phone but she was running CM7 RC2. I was able only fix it by installing sprint Lover.
Then as itohead said try to install Sprint Lovers and see if that works. If not then I think that there is something wrong with your phone and you may need a new one, or wait till the Evo 3D comes out and get one of those.
I forgot to update this. Sorry guys.
Took it to a sprint repair center and the tech said he's never seen that before and ordered me a new one on the grounds that my usb port was "broken".

So when I got my Nexus I had great 4G at work, i'd use wifi tether and tether my tablet all day with no issues, although I never did anything that required much data.
These last few days I can only get 3G at work, but I can get 4G in the parking lot. I don't understand why all of a sudden my signal has deteriorated. I don't know if VZW is able to see I used a large amount of data in one location and force 3G to that particular area? I've tried flashing new roms etc but nothing works, I had 4G today up until I entered the building, but just last week I could sit at my desk all day with full 4G
My first guess would be that it is an issue with the Verizon tower you were getting 4G from before. You could call them and ask if they are having any problems in your area. You might be getting a 4G signal from a tower further away when you go outside.
I know you can force 3G to save battery, but is it possible to force 4G and no CDMA? Im wondering if I can force it to connect to a tower.
Or is it possible to rescan for towers or something? I always download new roms and stuff and it sucks on 3G =\
Call Verizon and ask? Or maybe they have like a service-status homepage you can check.
Like maybe that is better than asking here, since this place is like about the Nexus and not a telecom provider.
Or should all people across the world SPAM this place with new threads every time their thousands of different cell-service providers have random local outages? Would that be tolerated?
Why should Verizon-customers be excempt?
Pull the battery, take the SIM card out, and then power up the phone. It should ask you for a SIM. Now power off and insert the SIM and power back up. See if it helps!!

If you did that, you'd get no voice, just data. Wouldn't want that.

You can update your PRL.
Seriously though, call in and ask if they're having network issues in your area. If you've done nothing to your phone and it had 4G in an area consistently before and it doesn't now, the problem probably isn't on your end. It'll take 5min to call in and ask. Hell of a lot quicker than troubleshooting problems on your phone that might not exist.
Try updating to the latest bootloader and radio for 4.03
Verizon is the largest carrier in the United States, not just one of millions of carriers across the globe. A lot of topics here correspond to the LTE version so you should expect topics about what is going on with them. Besides, this is GENERAL forum. Can post and ask about anything remotely related to the Galaxy Nexus, GSM or LTE version.
Seriously, if you aren't a moderator, you shouldn't be trying to police the forum. Keep your day job.

I've cleaned this thread also.
Once again, consider this a fair warning. If you have nothing to say relative to the question asked, move along and stop the childish bickering.
If you lost service only in your building it most likely has nothing to do with your phone and is cell-tower related.
Something I'm used to doing with previous smart phones that I haven't been able to do with the G Nexus LTE, is maunally update the PRL. So with that being said does anyone know how to do this or know of a program or app that can do this because I live in a rural area outside of 4g coverage, 3g works just fine, but I figure that me updating the prl would help me get back to full coverage as with my previous 3g smartphones without being in a 4g area, and yes I am aware that 3g and 4g refer to data, but as stated all my previous phones have been 3g phones so that may actually be a small factor. Any knowledge or assistance will be greatly appreciated.
Flash a radio in CWM if you are rooted. LTE phones do not use the *228 update as you have already noticed.. so this is the only way I believe

Thanks and I'll do that if I decide to go ahead and root my phone but I haven't done so yet because this is the first android in a long time that I haven't rooted lol and I know the benefits but the stock rom, to me so far, is better than what im used too, atleast for the moment.
Hmm, there seems to be some disagreement, saving *22899 as a contact and dialing does 'change' the PRL, it isn't clear from the comments I've read that it is updating correctly, although this number does seem to be autodialed by the phone in roaming situations. Some have said this will damage the SIM which I find a bit unlikely. Others have said that rebooting the phone without the SIM (turn off first) then rebooting again with the SIM will, and some say that the PRL is updated every time you reboot... Since I haven't had roaming issues yet, I've not tried any of them...
*228 does damage the SIM.. that's why it's blocked from an LTE phone.

What are you basing this comment on? Speculation? Rumors other people posted online?
The mere fact that many GN users (myself included) have had their phones auto-dial *22899 is pretty clear evidence that it isn't "bad" for your phone. At worst it may be unnecessary as the phones are capable of auto updating, but clearly its not "bad". My phone has been running 52642 for several weeks now and runs very well.
Pull battery, pull sim card, leave out for 90 seconds, re-insert both and reboot. This forces the phone to check/update the PRL.

We had a lot of people do it on Thunderbolt launch day and fry their sims. It was blocked shortly after by Verizon.

As above ^
Otherwise, feel free to dial *228 and tell me why it doesn't work.
Adding *22899 to contacts and dialing out updated my PRL as well. We'll see if it helps with signal out on the farm.

I just tried the *28899 seems to work? Although I'm still not sure how you get a keypad to show up to hit option 2 . But after I added it to contacts and told it to skip activation it programmed. Wish I would of checked my PRL version prior to updating so I'd know if it worked or not.
Works for me

Ok So I know there is alot of Speculation about this..
So I live in an Area where US Cellular and Verizon use each others towers. And my phone used to bounce back and forth between Extended Area (US Cellular) and Verizon.
After doing the *22899 while in a US Cellular area it updated my PRL my Radio reset and I Haven't Bounced back to US Cellular Yet.
I also for whatever reason am Now able to get 4G in our basement of where I work. Before I was lucky to get 3G But Now I get full 3G and when 4G pops up I get 1 Bar.
So I dont know how all this stuff works.. but I went ahead and did the *22899 knowing it could pop my SIM Card (I Used to have a Thunderbolt and Yep It broke the SIM on it when I first got it) But I was prepared to go get another SIM. You never know till you try it, is my Theory.
But Im happy to say, I have Full 4G at my Home. And I have 3G/4G in areas I used to never be able to get it.
BTW- the *22899 from talking to a Guy at the Verizon store said it forces the phone to Update/Activate Even if your in extended area. Thats the difference between *228 and *22899 I tried it out on my Dads old POS phone, its been in extended area since the day I got it for him.. Its just a Cheap Flip Phone. And now he gets 3G.
But yea Id only do this at your own Risk.. I maybe just one of the Lucky ones it works on.. Who knows.
I think as long as you do *22899, it will force the PRL change if there is one. Otherwise it will do it automatically.
*228 does not work though.
Me Epic Touch that is using Verizon Towers is constantly dropping signal, I have tried every modem from EK - FD but nothing has seem to help. I tried with Page Plus original Prl which shows roaming and didn't help and also loaded other Prl's that doesn't show roaming all the time that Straight Talk uses, but it does the same thing. I have had many Sprint Phones activated on Verizon side and never had any problems like I am having now and My Cousin has The same phone also which is on Page Plus and his phone behaves the same way. Was wondering if any of you that have this phone and flashed it to Verizon are experiencing the same thing? If anyone has any opinions or could weigh in on what I might be able to try or maybe tweak on this phone that might help I would greatly appreciate thanks. Forgot to mention that I have tried both stock and Ics roms and when signal drops it will have a circle with lone threw it but I don't have to reboot phone signal always come back seconds later but trying to hold a conversation on this phone is bout impossible without 2 dropped calls in a 30 minute period.
Is the phone activated on Verizon or are you just using their towers for some particular reason? Keep in mind there are issues outside of the phone that may affect connectivity - I just had this happen with our local Sprint tower last week. Took a week for Sprint to confirm the problem was the tower and fix it.
If you made a nandroid backup before you changed the prl (witch is what you should do before messing around with anything to do with your phone) flash back to it, see if that helps at all.
HTC Hero -> Epic 4G -> Epic 4G Touch
It is activated on Verizon unlimited plan. I also have a nanroid back up of the stock rom behaved the same way. At first I though it was Page Plus being I never used them and gave them a try instead of always worying about data issues with ST. I let my time run out on Page Plus and and switched to Verizon new 50 unlimited pre-pay but still acts the same way.
