[Q] How do custom ROM's roam without PRL's? - General Questions and Answers

I currently have a EVO 3D unlocked/S-OFF. I was curious if someone can explain this question to me? My guess is that it connects to the 'next' network and it might or might not get data/voice and try another.

Is it the sprint version of the EVO 3d or a gsm? If sprint, what is your PRL number?

I have the Sprint version of the EVO 3D. I am currently running a custom ROM (DisarmedToaster CM10) with no support for PRL that I know of. I have other ROM's with PRL support but I do not really run them. I just would like to know how a custom ROM makes the decision to roam and what network to try to roam on.

The PRL itself determines who you roam on and where it happens. While your rom may not display a PRL, the PRL is still on your phone actively working. AOSP roms like AOKP and CM are not be able to update a PRL so its good to have a compact or "senseless" rom to flash to do such updates since an AOSP rom makes you lose vital tools such as EPST.
I guess to answer your question originally, the rom doesn't use the prl, your phone does. Your phone's network status and PRL determine whether you roam or not. Download a senseless rom or small sense 3.0 rom, do a back up of your current rom and flash this because maybe you need to update your PRL to maybe a corporate one. There is a prl thread on the 3d forums somewhere with a PRL claimed to be a corporate that allows roaming without it being counted as roaming. Then you can restore your old rom.
Hope that helps.

[Q] How to enable EDGE connectivity...

All right I've went through all the posts regarding this and none of the options seem to work. I have terrible 3G/4G signal where I live. How can I set the network!!??!! Tried the apps tried the *#*# stuff (all I get with that is "RAT selection restricted!" WTF is RAT?) I can't even make a phone call or send a simple text with the one bar of 3G/4G I get. I know most are probably against the merger but I will hopefully benefit from it cuz there is a T-Mo tower down the street from me. Anyhow please help. I'm rooted, stock AT&T, 2.2.1

It's only possible with Rogers-based ROMs (e.g. Infused v2.x)
It's not possible with the stock AT&T ROM or any derivatives, and causes all sorts of problems with CM7.
Hopefully AT&T's Gingerbread update will fix this.

Would I be able to flash the rogers rom on mine? My guess is no... but its worth asking.

Infused v2 is Rogers-based.
Entropy, I was able to force 2G with Infused 1.5.3 when I had it paired with the Rogers modem. I used the star code *#2263# and that allowed me to select a GSM only band.
Also, on current infused.v2 builds, I cannot force 2G as they're not using Rogers modem and I don't feel like flashing another modem and bricking it on these test builds.

Oh, thanks for the info - it's the modem and not the userland! Very useful to know.

[q] some nv issues.

What's up guys? i'm from the evo community!
First off, i'd like to say once I get my issue resolved we'll be seeing some new exciting things from me.
Now I don't have much in this field.
Apperently I bought an evo shift flashed to metro, but it had a good esn on sprint, so i flashed it back.
now it drops signal and when it is in service the banner says "mymetropcs.com"
does anyone have any details on how to at least fix the banner?
it doesn't fix itself under qpst or cdma ws.
If its the banner in the notifications menu, I'm almost certain that's controlled by the prl
Sent from your Mom's Jitterbug
Just wondering if this is a solution for the Shift, I heard it on the EVO 4G forum but haven't tested it. Has anyone attempted RUU to a previous version then taking an OTA update?
I heard whenever the 2.3 update rolled our and it came with a new NV, the OTA wrote the proper things to NV. I would think it would do the same thing for the PRI.
Just advocating something I heard but haven't tested it.

Sprint Nexus S 4g on Boost Mobile - Questions

I flashed my NS4G to Boost... it was a long and agonizing road, but I think i finally got it working correctly.
my phone is currently 100% stock with gingerbread 2.3.7
since this was such a stressful flash, i'm kind of worried about "not fixing what's not broken"...
however, i'd love to re-root it and flash a custom ROM. Will doing this mess up any of the modifications i had to do to get calls, text, and data to work?
(they were all done in QPST)
I'm not going to do it until i have confirmation... so let me know and ease my mind!
thanks
-Randy
i also have a nexus 4g on boost. i've just about had every kernal and rom on this board for it (both gingerbread and ICS)
i hope that helps.

so a standard rom flash will retain all boost settings?
yes.
keep in mind mms fix only works on gingerbread as far as i know.
the APN can't be changed on ICS roms.

If you use voice dialer and say "open APNs", it will let you edit the apn. Does this not work to get mms working?

what you are talking about can not be talked about as it is illegal to change the esn and meid all all other device identifiers that are registered to the fcc. Each phone has a unique id to it that is represented to the fcc. I have also been talking with Boost employess and area managers and boost is getting ready to kick off the users who have "flashed" phones on Boost that do not belong on boost. This is going to be done as Boost can still tell what type of phone you have other then the esn / meid as the device still sends out certain other device ids to the network when you use certain programs. Also by trying to send updates to your phone sprint can request the system information from your phone that can tell them the actual make and model and firmware and all that you are running. And you thought carrier iq was bad...
if you wait a few months or so the evo 3d will be on sprints virgin mobile with ics included and sense 3.6...
Boost mobile will be getting the HTC Evo design 4g soon as well...
i myself dont understand why boost is going 4g when sprint is going lte... but another stupid move by sprint.
does anyone have a link to a how to flash my nexus s 4g to boost? I'd really like to do this. cant afford sprint anymore...

ATT vs ROGERS and how to swtich?

Okay so I'm currently running an ATT rom and radio combo. I want to first fully understand the difference between the two. I'm really unsure as to what the difference is and which one is better for what?
My next question is that if I am to switch from ATT to Rogers, do I just simply flash the new Radio and thats it? I've heard elsewhere that u must dial #*2.....something something and mess with the APN settings once u flash a rogers radio. What are the exact steps?
Also is it true that in order to get the capabilities to turn OFF LTE, I MUST switch to Rogers because it is "RAT Unlocked"?
Im having terrible service because I am in an LTE test site and I really want to turn it off and save myself the headaches from constant loss of data and reception.
I apologize for any repeated questions; I'm just trying to learn. I've attached my current build.
Thanks in advanced for any help.
I think yes roms are interchange but not all radios...and yes Rogers radio is RAT unlocked so you can disable LTE...which you can't do with att radios

Att to Tmobile lg g2

Just posted in main lg g2 forum QA. just thought Id cover my bases here to. Can I install a stock Tmobile rom with kernel/radio/modem/ on to an unlocked At&t LG G2 and it work as if it were a Tmobile LG G2? I'll of course be using a tmobile simcard. Thanks for any info

I don't know the answer but my question would be why would you want to do that? I'm on T-Mobile and except for this T-Mobile G2 I have always used an unlocked AT&T phone on T-Mobile. I get 4G LTE and certainly in the case of the G2, it is rootable whereas the KitKat T-Mobile G2 cannot be rooted (easily) and there is no recovery. I think you would be losing more than you gain by going to the T-Mobile rom if it is possible. Having said all that I'd certainly be interested to see how you get on if you can do it.
In the beginning of my tmo service I brought my gs4 over and just had to change/add APN settings. Still had to use Verizon ROMs, but had tmobile service. I would assume it would be about the same.

i actually wanna know the opposite of this. I got a Tmobile G-2 and am using it on AT&t (AIO Wireless techinically), but im getting super slow speeds. My DL is 1.1 and UL is 1.4 somehow. I havent rooted it yet because i have to RMA it back to LG due to the dead spot on the lcd issue. So after i get it back do i just need to switch the radio modem out to get on the at&t bands? Also would att roms work on my phone (d801)?
Thanks in advance for the help guys.

Double check the APN settings just to be sure. Also check different location / different time of the day. The speeds you list are HSPA so it seems you are connecting fine. I am on H2O (an AT&T MVNO) with a T-Mobile G2 and just measured 6.2 DL / 1.3 UL.
Double checked my apn and I'm all good there. Are you using a different radio? I'm still using the stock tmobil radio. I haven't been able to figure out what the issue is.

Well, this is what happened when I tried to do that. Whether it was just a bad ROM, or the ROMs are different because of e.g. slight differences in radio frequencies, I don't know. I do know, I'll never do it again -- that was the first time I've bricked a phone since having flashed my first ROM on the original Android, the Dream/G1. But YMMV.
On the other hand, there are ways to install features specific to TMO like boot animation/sound, wifi hotspot authorization, the TMO account app, and enabling wifi calling, to help "brand" it more T-Mobile. That's what I'm working on right now, in fact.
