I want to say that updating them will configure phone to use closest towers (at least I was told that for PRL) I was actually told that its a good idea to update them once a month in case towers added and network improved. Keep in mind, I was told this by a Sprint tech. Some are very knowledgeable and some not so much...

Help with update

Hey guys, I've been gone from here for awhile, but when I first go my et4g I rooted it and put AE mod 4.0. Now I can't install the update which I figured might happen, and I would like to be able to update to fix the LOS and still have root. What is the easiest way to do this? I'm not too concerned with keeping AE mod if that is a problem, but I do need to be able to tether, so I do need root.
Just flash the already rooted update in the dev section.

So after that flash is it updated or will I have to receive the update still?
EDIT: Feel real noobish right now but which Kernel is it? The way they have the things listed is kind of tough if you aren't sure exactly what you are looking for. I also just read a thread about different modems. Do I need to choose a new modem file as well?
The latest update is el13.. Look in the dev section, there week be a stock rooted el13 rom and some custom el13 roms. there is also the el13 modem and a modem. All flashable.
You won't get the prompt to update any more.

Thanks for the help, got it flashed hopefully this will be better. Have you noticed if the modem change improved service on your phone? I have XM on my phone and to be honest, I lose the signal so often on my work drive that it really drives me nuts. And at work when I tether my speeds are not nearly as good as they were on ATT. Kinda hoping this helps with some of those things. Any reason to think it would or wouldn't?
once again thank

Try updating profile/prl in system updates and reboot. If that doesn't fix it contact sprint and have them attempt to push it through reactivation.
But no, simply rooting the device will not solve the problem you're explaining. If the above steps don't work, just swap it out?? Clearly its not a widespread issue and likely has something to do with its activation.

Assuming you or he already updated the profile and PRL correctly and talked with Sprint (while on the phone to assure it is registered correctly!) I'd recommend using sfhub's stock root [http://forum.xda-developers.com/showthread.php?t=1433101] This provides a clean start with el29 modem, kernal and stock ROM, and provides root access. Since he's having problems I'd do a FULL restore (reset user data). I'd then use Auto Root with CWM - option C [http://forum.xda-developers.com/showthread.php?t=1342728]. That will give you a stock rooted phone with CWM for recovery and additions. Make sure all works. That may be enough. It could be just horrible reception at his place. Might want to check out an Airave device. There are also posts on how to tweak 3g/4g speeds [http://forum.xda-developers.com/showthread.php?t=1265990] Then if all is working maybe think about another ROM. I'm loving Blazer. Calkulin's and Strong Steve's are also super. Good luck.

am i a bad person?

A really nice woman came into my store yesterday, 1 day outside of her 14 day return policy. Her epic would not get a GPS lock and only ever has 1-2 bars. I didntt know what to do, as idd done all the basics...prl/profile, 72786, manually programmed...nothing worked. So I said **** it and flashed the fc18 modem to her phone. Suddenly, she had all bars and an immediate GPS lock. I know I shouldntt feel bad as thatss a good survey for me and a happy customer for sprint but I cantt help but feel like I broke some sacred rules and should be fired or stoned to death.
yes....yes you are a terrible person....
j/k idk bro it seems like you helped out a person that needed it. Are there any ramifications for do that down the road? Say she has another issue and comes back when you're not there?
man I think you are good, I would have done the same!!
If you have one more chance, try to flash the stock modem again once the GPS starts to work. I think it will work even you put the original stock modem back once it's started working. That will save your axx.
My gf works for sprint, she had to root and flash a custom rom to a customer's phone once(don't remember which) to get it to work correctly.
14 day return policy is @!#$()#$%@# bull****, if it wasn't for that crap I would have returned this because of the LOS issue.
I thank you for going above and beyond and actually HELPING a customer.
BUT, that doesn't make you a good person, you are most likely a scum bag like all of us.
Technically they cannot refuse service to someone who has rooted their phone. The MFG may not cover it but if you have TEP then they will work on it. We HAVE to, its policy. Anyone telling you they cant is wrong. So dont sweat it, if the customer is happy your gold!
She asked you to fix her phone and you did, what a jerk.

It doesn't if you ODIN'ed the modem. But it'll be an issue if you installed a custom recovery and flashed the modem from CWM. CWM would block the update.
I did the exact same thing yesterday

Potential blowback...
First off - no, you're not a bad person. In fact I'm pretty sure some companies give awards for service like that.
That said, if yours isn't one of those companies(...) you may catch some **** with the boss when she shows her phone to her friends and they come back asking for the "latest" software on their phones.
Just something to be prepared for....you totally did the right thing for the customer.

I agree. But, he should be safe either way because the average person don't even know what a "modem.bin" is, let alone know how to check which version they are on. She most likely thinks he did some magical thing that only Sprint employee's has the power to do. Assuming he's a Sprint employee.
EK02 update failed to install cuz many of us were stuck on the EG31 modem back then and only way to update was cwm.

Shell come back and he can run the latest .tar on her phone. Full stock, no triangle, no problem. I assume that's what anyone would do at the Sprint store, although I don't know how they do things there.
Yea she will be back when her phone wont accept the update and it starts to get annoying always asking to install lol.

How to force roam?

Hi guys, I hope someone can lend me a hand.. Does anyone know of any ROM that has a roam only choice? Is there any working widget? Any confirmed working app for our phone? I absolutely need this for a trip tonight and hope there is some option available to me!

Buy roam control.....

Used with 11115 , 11119 etc prl you may roam at 3g too...

Are there any potential ramifications to changing the prl like that? Im a rare roamer and would hardly use it. Maybe a dozen times a year, if that.

As long as you don't use a lot of data would be no problem....., if you were to constantly go over like 300 Mb they may caution you But if only a few times there should be no problem....the 00001 thread will always roam on VZW 3g ..read the prl thread it will explain more....

Update PRL and Profile w/out Signal

Is it possible to update the prl and profile w/out signal (not even roaming signal)? I'm wanting to flash an older modem to my phone to see if it helps w/ signal where I live. From what I understand, you need to update these for the new modem to take effect. Right? So! Is there an established way of accomplishing this task?
PRL can be manually pushed but flashing the same PRL thats already on your phone (you probably have the latest) will not make any difference. Not so familiar with profile on that note.

As long as its the latest it shouldn't need to be updated. 60690 was the last one i did but im not on touchwiz firmware so I can't update as regularly. PRL if out of date can make a difference.
I guess that answers my question. I'll just go ahead and start tryin out modems. Thanks for helping me out.

I believe you'll need to update the profile between modem updates.
PRL versions are location dependant. Your version will be totally different from someone across the country.

While I have seen some newer versions pushed to certain locations it also seems like 60690 and the one before it was common everywhere? Its kinda silly to not have a country wide PRL now that I am sure devices could store it easily. But yeah you hear people talking about receiving one in a specific state or area all the time. As many people who travel on sprint's network it must suck to have to update PRL everytime you land to get the best service.
I just remember when 60690 was pushed, seemed like we had every state check in that they were on it..
