Ok here is the deal SVDO is talk and surf when on 3g services it is not possible on the S4 some people say they can when on 4g since the S4 uses the sim card for 4g yes it can happen but not on 3g since that is CDMA only when phone call happens it shuts off the 3g(cdma)and leaves only 1x(CDMA) but if your on LTE maybe WiFi yes. The only devices that sprint had working SVDO is the EVO4g lte, HTC One, and the S3 that is because they had duel CDMA radios.

Unlock for use with other carriers

Has anyone tried Chainfires "Region Unlock" app on the 720T? Works on a lot of devices. Really want to find a way to use 720T on Verizon ALLSET 4G LTE. I'm already using ALLSET now only have 3g though.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
I don't think its possible to use verizons LTE as sprint and big red use two different LTE bands which the sprint gs4 doesn't support.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] GotChanged:
I wasn't sure I do remember when using att s3 on T-Mobile for a long time there was no way to get 4g then someone figured out how to open AWStats bands. It was in a thread where it was argued the phone didn't have the hardware even citing FCC specs then a thousand pages later it was proven otherwise. I could be wrong about which carriers but I'm hoping this 720T has the hardware for Verizon 4g lte. I also don't have any other carriers sim cards to see what Chainfires "Region Unlock" will do as in maybe unlocking for GSM carriers T-Mobile or AT&T?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
The region lock is ONLY for Note 3s at the moment.

Flashing CyanogenMod from ClockworkMod Recovery

*Go to end*

Hey all, I'm new here and I've run into a problem. I thought I'd post it here in case there is anyone who has knowledge on how to fix this. As the title suggests, I recently purchased a Galaxy S4 (Sprint) and tried my hand at flashing a custom ROM (CyanogenMod).

I completed all the steps from jflte section of their wiki and wiped all the data and cache.

I mounted the latest nightly version of CM (called "cm-11-20140802-NIGHTLY-jflte.zip" from the jflte downloads page to /storage/sdcard1/.

I pushed the CM .zip to said sdcard1 folder, but when I try to install it, I get these messages...

Finding update package...

Opening update package...

Installing update...

Checking if loki-fying is needed

/dev/block/platform/msm_sdcc.1/by-name/boot needs lokifying.

[+] loki_patch v2.1

E: [-] Failed to mmap aboot.

E: Error loki-fying the boot image.

If anyone has knowledge of whether I need to somehow find a different version of CM or edit/add "lokifying" to the file specified, I would be eternally grateful. I can't use my phone until I solve this.

EDIT: Should I try my luck with Odin?

EDIT(2): I rebooted the device because I intended on trying tomorrow. To my surprise it started just fine and everything looks ok. Now I'm wondering, are there any potential long-term effects of the boot not being lokified?

In regards to the whole surf & talk feature our phones are physically incapable of, AT&T has a Triband S4 that's capable of doing this. Presumably, could there be a software fix for this?

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] DroidJer:
Thanks TD. When you so, could you also check to see if you can turn LTE on and off without rebooting the phone? When I switch my network mode (say from CDMA, to LTE/CDMA, or Automatic; for example), the phone goes into a reboot for the change to take affect.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Dngrsone:
Has anyone had problems turning their phone on after turning it off? I don't know if it's because I am using nonstandard chargers (or solar charger) and pissing it off or maybe I should just not turn the stupid thing off; because I have to wait half a day before it will deign to turn back on.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bryguy9021:
yes if a charger is plugged in to it. sometimes it wont turn on. sometimes it will only boot the battery level. easy fix is hold vol up and boot recovery then reboot to system. also I don't turn my phone off that much anymore :P
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] td030981:
Ok.....report time. I reloaded candy rom and tried using the data while making a phone call. I made the call first and I could see that 3g was still up on the notification bar. But when I opened the browser, it would not load. So no browsing while making a call. Even though 3g is up there, it's dead. Couldn't figure out how to take a screen shot to show the 3g. DroidJer u shouldn't have to reboot when switching from 3g to lte. If u switch and it doesn't pick up, try going to airplane mode or find an app that cycles the radio.

TD, since I bought this phone I've had to recycle the phone whenever switching to 4G from CDMA. Please take a look at the ScreenShots. Am I the only one, and if so, anyone know how I can fix it?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] DroidJer:
To clarify, switching onto any of the network options prompts me for a reboot. This is really annoying.

Also, when I leave it on "LTE/CDMA," I miss calls, & get horrible reception and call quality. So I generally leave it on CDMA until I need a fast connection. Does anyone else have the same experience with "LTE/CDMA?"
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] td030981:
DroidJer my phone doesn't do that. Once I make the switch it changes automatically. And I don't have the issue with call quality that you are having. And I always have lte/cdma selected.

SPH-L720T on SuperS4 Rom

SPH-L720T dropping network connectivity

I have recently picked up the GS4 (Father's Day-ish). It has been too long to return it and not long enough to get something else. I am unsure if it has something to do with the Spark/Triband crap or not but I have issues constantly with what i can only assume is network switching. Almost daily I lose LTE / 3G and CDMA but, If connected to wifi all non text/call data is fine. Problem is it will not switch back on. After a reboot it goes back to normal and I pick up on everything again. Usually 2 or 3 text messages pop in that had been in limbo for what could have been hours without me knowing it. This started while the phone was stock. I have since, rooted, removed some bloatware, used the Samsung 'Refresh Customization' app from the playstore and nothing seems to correct the issue. I have set the network to automatic as well as LTE/CDMA. The only thing I have not tried is CDMA only. I do not want to go without the fast data connection.

Has anyone else ran across this? Can it be fixed? What did you do to fix it?

There's still a lot of work. And I have no way of connecting my device to a GSM network. But I have a good friend out side of the us and he's making good progress. currently we have no account to unlock and then compare .. so for the moment development has slowed..

To be very clear. Domestic seems to be working.

International is going to be a WIP because of the red tape from sprint.

but at this moment it looks like a simple call to sprint (MAY) provide over seas unlocking. ;)

Great post Thanks. Doing a little searching for a safer way to get msl number before trying, since this method required running an unrated apk (not that this apk contains any malicious code). I'm just in the security profession and always take the safest road when possible.

I found an app in the play store called "msl reader" that may work (haven't tried it yet, still looking around). "Msl reader" requires root, but at least the app made it through some Google scrutiny which lowers the risk some.

Please know that sometimes when the user upgrades to nc6 they lose the spark graphic during boot, but they don't actually lose spark. This is a known issue. The graphic can be restored using the customization refresh app listed in the MISC section of the op.
