[QUERY] EVO 4G LTE stuck on 1x - Sprint HTC EVO 4G LTE

Well to start with, I am from India and used many handsets with Reliance CDMA. In past, I have used Palm Pre and Pixi, HTC EVO, EVO 3D, Samsung Fascinate, Epic 4G touch, Nexus S, Galaxy Nexus, etc. All handsets were fully configured to work for Voice, SMS and 3G/Evdo data.
Background:
To get any device running on my network, the MEID has to be registered with the network, PRL to be uploaded, PPP and HDR user/pass has to be injected and it starts working. Procedure remain different from one device to another but majorly the above has to be done.
My network has Rev:a EVDO service besides 1x.
The problem:
The problem is with EVO 4G LTE is that I am not able to getting Evdo/3G signals.
Observations:
As soon as I turn on the phone, the network starts to show 1x-RTT instead of EvDo-rev.A:8 which appears on my other phone. The place where I am is well covered by EVDO/3G network so I dont think problem from that side. .
What I tried:
1. Correctly configuring the user/pass using DFS and QPST.
3. Uploading RCDMA PRL using CDMA WS, QPST and DFS.
4. Downgrading radio version for all available radios.
Earlier I felt that due to radio version, the problem is arising but I have tried with all the radio versions but the problem is still there. So now I feel that due to something is preventing the phone to connect with EvDo network.
Looking forward to you guys to diagnose and solve the issue!
Few screenshots:

These are screenshots from 2 phone, left one is mine which is stuck on 1x and the other one is fascinate which has Evdo working. Let me know if something can me made out of it. (My Country code is 404 00)

Any help guys....

I have confirmed once again from my service providers and my line is working fine, so something is wrong with the phone only. Guys, please help me.

Have you tried ##SCRTN# ? Type that into your dial pad. You will need to know your MSL, which you can get by downloading an MSL reader from google play.
If that doesn't work then try unrooting and relocking your phone. If it's still a no go, then take your phone to a Sprint S&R store. Make sure it's at least relocked before you take it because they will most likely want to try flashing the phone with their RUU which it needs to be locked to do.
If that doesn't work for them then they will need to replace it because it's most likely a hardware issue. If you don't pay for TEP then you'll have to pay $35+tax to have them do that.

Have you gone into the dialer settings and changed the frequency to either of the two options? If so, you need to be on the PCS band where Sprint gives their 3G. It's normally on automatic but after changed, it is NOT easy to get back to automatic.

Unfortunately, I am not on Sprint. I want to understand how can there be a hardware fault when the radio works well on 1x but not on 3G? Also, all other things are working fine for me.
Seems very illogical to me!

No More Roaming on Verizon With Sprint Mogul After 3.16 rom / 3.27 radio Upgrade

Is it just me or is anyone else unable to roam on verizon towers after the new rom/radio upgrade (3.16/3.27)? I get a recording while roaming "Welcome to Verizon Wireless, We're sorry, we're currently unable to authenticate your phone, Please try your call again. If you continue to experience problems please hang up and dial #8899 from your wireless phone"
Any help is appreciated.
Thanks
What PRL do you have?
I never tried making calls but I don't roam on their towers anymore when it comes to data. I just get the triangle and 1x and no web browsers will let me connect to any sites. I kinda just gave up on it since I only needed it in the DC Metro.
I can roam with the new rom. im using prl 60610 and data roaming works as well.
kind of ironic because it didn't work before for me
1X roaming works on Alltel and VZW with 60610 and 3.x ROM here, but EvDO roaming is a no go on Alltel, even though it works fine with 60610 and 2.x ROM.
I guess you are not the only one having the problem. it's a no for me for both prl 60610/60611.
However I am only having the problme at home. I can roam onto vzw at different locations (voice and 1x data) $%^%^&#!$#@!$
People say it may have something to do w/ a-key which is blank on my phone ...

Using PRL 60610. I downgraded my phone back to radio 1.40 and it worked fine but it will not work with the new one. I guess roaming had to be given up for GPS.
Problem Solved. Seems like Sprint's System wanted to do the PRL update themselves for record purposes because after I got the rep to shoot a new prl (60611) roaming worked. I then downgraded to 60610 (best one for me) and viola it stuck. everything is working now.

Ok, so how did you fix this again? Can you give me the current setup of your phone or the steps you took to get to where you are?
Here is what I have done so far:
- Flashed from 2.17/1.47.1 to 3.16/3.27 and got the no Verizon roaming issue you described.
- Figured it was an issue with the new ROM, so I then downgraded back to the stock 2.17/1.47.1 ROM from the HTCAmerica website. (The downgrade wiped all my settings for MDN and MSID) However, the issue persisted.
- I updated the PRL to 60611. Still no luck.
- Called Sprint, who initiated an over the air PRL update of their own to 60611. Still no Verizon roaming. Sprint says they are "investigating" and will get back to me, whatever that means...
The only other thing I can think to do is to downgrade again back to 2.09/1.40.
Also another question, when you view ##778#, does your phone show anything on the "A-Key" page under the "Authentication Key" setting now that you have roaming working? Mine is currently blank, and I have read a couple threads talking about needing to figure it out, but those users all seemed to be Verizon customers. I would be interested to find out if Sprint customers have that setting or not.
This issue is driving me nuts, and any help is greatly appreciated.
Call sprint technical support and tell them you need an "HLR Reload". If they don't know what this is, ask to speak to someone who does.

Wow. Genius! Got Sprint technical support on the phone and asked for the "HLR Reload." The guy knew exactly what I was talking about and was able to do it right away. I am now able make calls and get data while roaming (currently using 2.17/1.47.1).

Still wont work for me *sigh*

I called and had them do this, but i had no luck. Still no EVDO roaming in places where there should be. I can make and recieve roaming call and data roam in 1X but evdo is gone. This is on both the 60610 and 60611 PRL. EVDO roaming worked on both PRL's with the 1.47 radio and 2.17 rom.
Any more ideas?
well I thought I didn't have these problems, but now I'm not certain. I don't think I've ever been able to EVDO roam on verizon, at least not sice I started paying attention which was already after moving to a 2.17 with 1.40 radio and orginal PRL. I know verzion has evdo in this area, but sprint doesn't. Maybe there is no agreement here for evdo becuase of that? I guess it couldn't hurt to try this trick and see if I get it.
I found more problems using 3.16. I did encounter the roaming authentication error. So I called, got the HLR reload. That made things MUCH worse. Now nothing works. My MSID and whatnot are all correct and I see signals, but can't make calls or data connections. Sprint tried some things but nothing worked. I'm going to do a hard reset and see what happens.
Sprint was surpisingly willing to work with me knowing that I am using the test rom though... but in the end still suggested I revert to an official rom when nothing worked out.
Anyway, not sure I'd reccomend the HLR reload on the 3.16... try at your own risk.
holy crap
sorry to hear that
if you get it figured out, lemme know what fixed it.
I suspect sprint just hit the wrong button. I hard rest... still no dice, but I noticed that dialing *2 does work.. normal numbers and network don't. Seems like an authentication issue. I doubt seriously it has anything to do with the rom, but I just flash 2.17, casue otherwise I don't hink I'll get far with sprint.
Now when I try to make it call it tells me the phone has not been activated. (with 3.16 I just got the call end dings imeediately)
SO when I fix this and flash back to 3.16, will I dare to try this again after roaming gets broken again?... tough call.
Edit... still need to fix MDN and MSID in the 2.17 .. more soon.
Edit: fixed MDN and MSID in 2.17... now having the same problem as in 3.16... ding ding ding... no call. Looks like I have to call sprint again.
ON the phone with sprint now. Have rebooted for them a couple of times. This guy is still stumped and he doesn't seem generically ignorant.
I started a new thread for my issue.
http://forum.xda-developers.com/showthread.php?p=1881522#post1881522
You might want to read it before doing any HLR updates in 3.16 though. I'm on my third rom today and a few hours with sprint tech and I still can't make calls.
(EDIT
SOLVED... see above thread. It seems they messed me up badly when they did the HRL reload... however.. it doesn't have to be done badly... at least now we know the fix if it happens to someone else.. so don't let my experience stress you too much. Now to upgrade roms again.
and voice roaming works now..
Roaming not working
ahhh!!! after the upgrade, i cannot roam on vzw...
Called and spoke to several reps... no one knows what HLR Reload is... according to them turning the phone off and taking out the battery for a few minutes will force the HLR reload....
I don't know what to do.... These reps are impossible to deal with.. Anyone have any suggestions?

[Q] Thunderbolt 4G LTE not connecting

My co-workers phone service got cut off recently, and after it was re-connected, she lost 4G. I had her on Synergy 255 and had the latest radios I found which was CDMA: 1.48.00.0906 LTE: 0.01.78.0906. Even when I updated her to Synergy 262, the problem persisted.
Anyone know what might have happened, I know the recent OTA update for gingerbread has been giving people problems, is it possible the OTA update problem also affected her phone since she was already in gingerbread?
I just put BAMF Forever 1.0.7 on her phone, and it's still only able to connect to 3G, is the problem on verizon's side?
Check your settings in say an app like LTE on/off make sure she is in LTE mode or cdma/LTE

Unroot it, return to stock with the full RUU and see if its busted. If it is you probably have a bad radio in the phone...I had to send my first TB back a week after I got it for this reason.....
Customer service was very helpful believe it or not, just make sure you tell them you have already done a hard reset on the phone, done the OTA's and 4G still doesn't work. The will ask you your build number, etc. to make sure it matches what's "in the system".
So just return to unrooted Froyo, do any and all upgrades to get it current, if it still doesn't work you should be able to get a new phone.

Sim card
Another idea is that the sim card is dead.
Verizon 4G sim cards can't be reactivated once their deactivated, this happens when you try activate a 3G phone on verizon from a 4G phone, the sim will be dead in 24 hours, I'm guessing the problem may be the same here, once the SIM was disconnected in the system, it can't be reactivated.
Unfortunately to get a new sim, you'll still have to return to unrooted stock to get support from Verizon, but I expect the phone itself is just fine.
Verizon employees are still somewhat inexperienced dealing with these 4G sim cards from what I've seen in stores, so they may have failed to account for that when they reactivated the service.
That seems more likely to me than the phone just happened to break when the service was disconnected.
Did you ever try just flashing another radio? It's worth a try. I would try flashing the radios from the 1.70.605.0 build.

You we're exact on the mark about the sim registration. I told her to replace the sim. And sure enough it worked after it was activated. Glad I didn't I have to resort to going stock and unrooting... She probably would've beat me up...

[Q] Thunderbolt VZ to Straightalk

I'm a noob here, but other places i'm not. I have read VERY many posts and the gist of owning a thunderbolt is that it only work(ed) on CDMA VZ so it is not compatible with GSM although it has a SIM card because its is/was locked to VZ only frequencies.
Just to make sure, I called VZ to attempt to get an unlock code saying I was going on a trip overseas and needed my phone to work. I was told that if I upgraded via the OTA to ICS, my device would then be compatible with GSM and I could simply use any SIM card in my phone and get it to work.
What I am trying to do is move over to straightalk away from VZ.
Instead of unrooting, I flashed the radios and ROM available on this site and ICS is up and running.
So has anyone tried straight talk yet on ICS?
That doesn't sound right to me but I would be interested in finding out whether or not it works. From what I understood about the antenna in this phone is that it is locked in on the 700mhz band at a hardware level. Also there are no settings to change to GSM in the network settings.
Sent from my ADR6400L using Tapatalk 2
Hmmm. Don't know why tech support would lie though -- especially when I waited online for about 30 minutes throughout the conversation. I've been a customer since 1997. He even said, after I switched to ICS, simply insert new SIM and I'm ready to go.

They may not be lying but rather don't know what they are talking about lol. They are wrong all the time. Just because we have a sim doesn't mean that putting a gsm sim in makes it possible to use on other networks. Give it a try maybe they finally did make it possible. Like I said I thought at a hardware level this phone was permitted from using gsm bands.

RE: Thunderbolt to straight talk
Granted, they may be wrong. But, all the many hours of reading I have done, says that CDMA only phones don't have SIM cards and my TB does. And per another posts GSM in the USA operates on more frequencies than abroad. Why would HTC create a phone with a SIM card if there was no reason because it was only CDMA?
Regardless, I purchased a ST SIM and an unlimited plan to try out. I'll post back after I see if I wasted my $$$ or not.
The LTE frequency Verizon uses is actually a GSM which is one reason. Verizon owns the upper c block of the 700mhz spectrum. Also, because Verizon is originally a CDMA carrier they had to use another antenna in all LTE phones in order for them to function. The LTE antenna uses data only. It is not equipped to make phone calls unless a phone call is already in progress in which case the phone is routed through the LTE antenna and is then made over the data connection much like VoIP.
Sent from my ADR6400L using Tapatalk 2
disconnecktie is right, the Thunderbolt can not connect to GSM services. The sim card is not a GSM sim card, its is a 4g LTE sim card. Just because its called a sim and looks similar, does not mean they are the same. The guy you spoke with on the phone probably knew nothing about the Thunderbolt and just assumed that because it has a sim card it would connect to GSM networks.
understandably.

"The LTE antenna uses data only. It is not equipped to make phone calls unless a phone call is already in progress in which case the phone is routed through the LTE antenna and is then made over the data connection much like VoIP."
So theoretically, if there is an LTE only antenna....how does a call get routed regularly when LTE networks (such as 1G and 3G) occur when LTE network isn't available to pass the information over the data connection? More than one antenna?
I'm not expecting this card to work in and of itself. I'm going to swap out another GSM to see if after ICS upgrade, it is actually opened as promised. Now if it doesn't have the requisite antenna, that's understandable, but in that case, why theoretically couldn't I just get a GSM antenna and swap it out for the CDMA one? Can't be any worse than replacing a wireless card in a laptop?
Based upon the "answer" given to me by VZ tech support, I have to wonder if there really is a different antenna or simply the "sim" card installed locks it into the frequency -- and the OS lock(ed) into the sim card previously. A SIm card is essentially what allows you to communicate with a carrier afterall.
Definitely interested if this works, thanks for attempting this

All the LTE sim does is authenticate your phone on the network. That is the reason *228 is no longer needed.

The thunderbolt does not support GSM. It has 3 radios, two 3g cdma which enables svdo or simultaneously voice and data over 3g. FYI some new 4g phones won't do this. The LTE is data only and no phone calls are placed over LTE on any phone for vzw. VZW is not setup for voip yet and that won't start until at least 2014. The thunderbolt is not global ready even with ics. There is no apn info to edit. This all has been discussed many times over the last two years.

I'm no cell tech and I get what you were trying to say. I apologize the last part of my post was a little rude. I don’t think voip and svdo are even close, I admit I could be wrong. Voip uses a data connection to place calls while svdo uses the cellular connection for calls and data. If you place the phone into airplane mode, connect to wifi you would not be able to place a call. If you had voip you'd be able to place a call. I know many carriers offer some sort of 3g to network extender that creates a similar type of connection.
Sent from my SCH-I605 using Tapatalk 2
Svdo also makes it so that calls can be placed over 4g when it is present which is like VoIP. Either way I know it isn't exactly the same but was merely using VoIP for a comparison.

In my original post above I incorrectly used VoIP when I should have used VoLTE, I knew what i wanted to say, but used the wrong terms which can lead to confusion and this is all to the best of my understanding
The Thunderbolt as with all 3G cell phones make phones calls over 1x voice network while data is handled by 3G network. The thunderbolt does not make any phone calls over 3G or LTE, it has multiple radios which allow SVDO, a 1x for voice calls, a 3G radio, and a LTE radio. Calls are placed over 1x and data is handled by 3G or LTE whichever is available.
The link below has a good discussion and more clarification on the Thunderbolt when it was first released.

I realize that it has been "talked" about. But based upon conversations with VZ support perhaps it was time to rehash it based upon what I was told.
As far as the APN to edit -- after ICS update (non over the air -- the one provided here). See screenshot. There is even a folder created on the SD called APN Backup restore.
My phone is rooted using revolutionary and running the ICS deodexed, etc. found on xda-developers.
Based upon what I was told by VZ tech support, I purchased a ST test SIM with unlimited service. I installed it today and get SIM card is from an unknown source. I googled that and it appears to be locked. I thought I was unlocked and rooted using revolutionary. But now I question that. So am I truly unlocked like I thought I was? I then tried getting the unlock code using fastboot as per instructions on HTC's development site using oem get_identifier_token waiting for device, and I get stuck at "waiting for device" with no information ever coming up. The only way I appear to be able to communicate w device using ADB is by letting the phone boot then connecting it via usb using debugging mode, and always awake, then it appears as a device, but that's where I get that waiting for device message.
Meanwhile, with the ST card in it's downloading email. I just cannot send.

Your phone is S-off, and rooted, unlocked is totally different. Unlocked means that verizon has allowed that phone to be used on other networks and carriers. You should really do some research, you will find that the thunderbolt will somewhat work on straight talk for a little while, then they will kick you off the network. Just google it instead of questioning everything people say here as they are just trying to help you and you seem to want to do nothing but argue anything that is said.

First off, I'm not trying to "argue" with anyone. If these forums are not to ask questions, then what are they for? With that said, as I previously stated, I have spent HOURS which have amounted to DAYS reading not only the forums here and elsewhere and the information conflicts -- and I may have updated information who the heck knows. You never know when there is false information out there floating around and when it becomes outdated -- and the only way to update that information is by sharing upon these types of forums, I would think. You take your car to an automechanic and he tells you the entire transmission needs to be changed, do you just say ok or do you ask questions until you can fully understand the scope, do you do research, and if that research conflicts, do you ask for a second opinion or simply tell him, ok, go ahead and change it?

Your phone is S-off, and rooted, unlocked is totally different. Unlocked means that verizon has allowed that phone to be used on other networks and carriers.
And as far as unlocked by Verizon, I followed a post until I reached an HTC forum indicating it can be unlocked for all carriers....by replacing the carrier OEM identifier token with an unlock code in binary format from HTC. See what I have pritned and attached.

I think your issue is you read too much into this. Yes, your phone cane be unlocked, it can run on other carriers and networks.
Your phone can however only use CDMA carriers and networks. Just because it can be unlocked does not mean it can be used on networks that do not support the hardware your phone was made with. nothing can be done with software to change that.
Your second problem is, you are misunderstanding terms, and HTC them self are not helping this. The PDF files you linked say unlocking, they refer to unlocking the bootloader, meaning you gain S-off (you can flash files) The unlocking you are questioning here is to get your phone working on another network.
Those 2 things are entirely different.
A phone is designed to work on specific frequencies when it is designed. Some phones are CDMA phones, some are GSM phones, and some are global (they use both). This is a hardware thing. Nothing changes this once the phone has been made. Our Thunderbolts are CDMA phones, unfortunately we can not just up and go to AT&T or anywhere we want with this phone.
I am sorry for being argumentative with my last post, you are right this is a place to discuss issues like this.
If you search for StraightTalk you'll find that it may be both CDMA and GSM supported depending on where you live. If you search for Thunderbolt other carrier you'll find that some people have had limited success with missing functions getting it to work on other carriers.
If Your switching to another carrier, buy a phone for that carrier or a global phone. It's a lot of work getting a phone to work on another carrier and you can get a smartphone better than your thunderbolt for a low price on a MNVO. If your dead serous on taking your thunderbolt to another carrier it loks like Page plus is going to be your best bet. USE EXTREME CAUTION when flashing your phone as you could brick it and it would do you no good at all.

[Q] Lost 4g but still have 3g. Need some help!!

I lost 4g a few days ago but now have 3g. I flashed many different roms and still can't get 4g back. I downloaded an app to try to fix it (4g toggle). It made 4g reappear but can't do anything on it. I believe it's a rom that did that. I played around with the sense rom 5 roms that were available. It could be one of those that did it. Not sure. I flashed and unflashed many kernels but still nothing. Can anyone point me in the right direction to fix? Also, it's not the sim card because 4g appears in the Galaxy Nexus as my backup. Thank you.

You may need to flash RUU. I have had this issue before while testing different roms. Once on the ruu, you should get 4G back.

I tried that but no luck. I'm going to see if I can get a new sim card just to see if by some mystery this works. I can't see how it works on a Nexus with 4g but not the device. That sounds like something weird.
This happened to me on my old phone and I called verizon and asked them to do a dmu reset and then it came back.
Try that and hopefully it may work otherwise get a new sim card.

Remember that HSDPA is not 4G but a very accelerated 3G data network. That may be why your Nexus show's HSDPA but your DNA will not register 4G. LTE is 700 while HSDPA is a more broader spectrum. Are you using a TMO Sim or a Verizon Sim?

I'm using a Verizon Sim. I will call them first and have them do a DMU reset for me. If that doesn't work then I'll get a new sim card. Thank for all your help folks. I'll let you all know which one worked.

Make sure you aren't setting you preferred network with the 4G toggle to LTE only. It would need to be LTE/CDMA or LTE+cdma+evdo

Key Notes for Verizon Galaxy S4 (AWS LTE) on T-Mobile's Network

After happily using my 'old' S4 on T-Mobile with HSPA+ since having the Note 3 as my primary line, I was naturally excited to update the baseband and unlock Band 4 LTE. However I noticed some caveats which I've now solved which will undoubtedly confuse everyone at some point.
Assuming you've got the correct APN for T-Mo (fast.t-mobile.com) and naturally install the SIM, if your phone is on global you will happily see working LTE but not so fast (no pun intended). If you call or text, it fails. If you quick check your About -Status in settings and look under network it will say say Unknown and not T-Mobile. Why? Essentially you're in LTE data only mode because by default the baseband is looking to connect to CDMA for everything else in the CDMA/LTE marriage that is Verizon unique, which obviously won't work here. The assumption otherwise is that you will only need GSM if traveling internationally so it never looks for LTE with GSM.
The quick easy fix is to drop out of Global back to the GSM/UMTS setting, which will bring everything back, network restored to T-Mobile, but now it won't use LTE again, lame.
Luckily there is a fix. Use the PhoneInfo app or however you prefer to get to the Testing App. Under device information change the dropdown to LTE/GSM (auto PRL). Toggle airplane mode or restart. When it comes up you should be on LTE and quick check settings again you'll see T-Mobile, and everything will work. So far this seems to hold pretty well.
EDIT: Note: This works for TW Roms. I have not had success in CM10.2. In CM I've only gotten LTE data (wrongly labeled Verizon) and nothing else. Doesn't even pick up my phone number regardless of settings used.
Can you send me the link to the TW rom you are using for this? Thanks!
A walk through would be nice

Use this app, hit Device Information, and change the dropdown to LTE/GSM (auto PRL). Given the simplicity not sure you need much more of a walk through than that. A video would require a bunch of editing to blot out IMEI and phone #s.

I am using this app and it is great. When it works, it would show T-Mobile as Net. Op instead of Unknown. Only issue I am seeing is that 4G LTE signal is not so great over where I am at and once in a while it would drop to H+ and then get back to LTE. During that cycle, the Net. Op would become Unknown again. Wish there was a way to fix this permanently like tricky the SMS app to send GSM or whatever it is causing Net Ops to be unknown.

Couple of things. Remember as I started with the baseband in i545 when on LTE really wants to use CDMA as the default so when it's searching it's not going to obtain GSM as instantaneous As it otherwise would. Don't see any specific way of that getting patched ever as we're going against the grain of how it's typically supposed to be used. If you are on a fringy area for it, you may be better off just leaving LTE off, H+ speeds are practically the same anyway. Tmo is only using 3-5mhz channels for band 4 as they use other channels too so for us it's not going to be superfast like Verizon on average anyway.
My phone is in Global mode, I have fast LTE internet and calls/texting works just fine. I am using a Verizon S4 with MJ7 and a T-Mobile simcard. No need to change anything except the APN and switch to Global.

yep, cant really install anything on MJ7 since there is no official root even, so yeah, bone stock. Fastest I have gotten the internet to be was 25-26mbps download which isnt great, but for a cellphone is more than enough lol
So maybe the MK7 bootloader fixes this SMS issue...
How is this holding on for u ? I got it to work one time with hyperom and I restarted and it doesn't want to work. I did however get it working completely on a mj7 ROM and gummy kikat ROM. Weird.

If you happen to have an MDK and want to run CM10.2 with GSM service run the ATT "I337" ROMS, fixes all the Verizon CDMA quirks

I did that and it kept failing.... TWRP recovery just would not get it to take.
So I flashed the MJ7 rom again and I got it working on it. I'm not sure why it didn't work on hyperom. Very weird. Tried the method and nothing. But I tried the method on mj7 ROM and it works perfectly. Weird weird weird.

so using the 4.4 gummy rom you were able to connect to LTE / HSPA+ networks easily? And SMS / MMS worked just fine? Upon trying with the MJ7 update, non-rooted, I could only connect to Edge services under the GSM profile. Using global would barely warrant the HSPA band.

Are you actually getting "LTE" or reframed 4G?
please school me how to change apn.
well let me give you a trick, flash an i9505 rom which you can find them here http://forum.xda-developers.com/galaxy-s4/i9505-develop
then flash any verizon kernel (because if you just flash an at&t or t-mob rom it wont reboot it will say triangle and not authorized verizon software)
dont forget to update your baseband to lastest then you can enjoy LTE (and fast) without any problems.
if you get and prop. issues while flashing international roms just change the "updater-script" first line to :
assert(getprop("ro.product.device") == "jfltevzw" || getprop("ro.build.product") == "jfltevzw"
then you can flash anything you want.
Here is how I did it
Here is how I did it, but needs some minor updates since then. Please let me know if anyone tries it and is happy with the result.
