[Galaxy S 5 Q&A, Help & Troubleshooting] vndnguyen:
Hi,

APN settings are used for MMS messages and Internet access. It does not affect the SMS function.

SMS setting is just the SMS Center Address, that is stored on your SIM card (not on your phone), so typically it will not be affected by changing a ROM.

Try the following:

1- Put the SIM card into another phone and test SMS, to make sure your SMS function works fine.

2- On your Android phone, download another 3rd party SMS app (e.g. GO SMS...) to see if it works?
[Galaxy S 5 Q&A, Help & Troubleshooting] SgtStringCheese:
Sms works fine when I restore back to stock TouchWiz though. If I use a 3rd party messenger can I keep my number
[Galaxy S 5 Q&A, Help & Troubleshooting] vndnguyen:
That means the custom rom has the problem with the SMS app.

Of course yes.

[Moto 360] jt3:
For $40, you'd think they'd include a wall charger, but no... Dock and cable only. Sigh.
[Moto 360] 640k:
wait wait wait wait... how does it NOT include the wall charger???

i used my N7 2012 charger in combination with the Moto360 charger and it didn't go to the circle charging screen. The battery was charging, but it didn't dock until I switched to the included power supply. Is it an amperage thing?
[Moto 360] jt3:
Sounds more like a cable thing. The N7 2012 charger is much higher amperage than the OEM 360 wall charger. The dock will only draw what it needs, so higher amp charger isn't an issue.

hi

I upgraded to helmi 3.5 last week, all run good untill yesterday when the phone lost signal, it just has a '!' next to it i've tried soft and hard reset but still same problem. i've checked the wireless manager which says phone is on. does anyone have any idea how to solve this.would flashing the radio or rom again solve this

thanks
[MDA III, XDA III, PDA2k, 9090 Software Upgrading] fraser:
Try booting up without a sim card, switch the phone on and off again once or twice in Comm Manager, then put your card back in.
[MDA III, XDA III, PDA2k, 9090 Software Upgrading] jonni1980:
tried that but no luck. in the phone settings it says 'no service' do you think the radio has failed or possibly it needs sim unlocking again
[MDA III, XDA III, PDA2k, 9090 Software Upgrading] fraser:
"No service" suggests that the phone itself is on and not seeing anything. Otherwise you'd be seeing "Phone off". Have you tried any other sim cards, or even giving your own a wipe?

Just did sim unlock for international use with ng2 modem

it worked.

followed the method mentioned by OP and upgraded modem back to ng2.

i upgraded modem incrementally

NG2 -> MDC and then sim unlock

then

MDC -> MDL -> MF9 -> MJA -> MK2 -> NAE -> NG2

i lost my wifi after upgrading from MDC to MDL and did not get it back until went all the way back to NG2. the moment i installed NG2, my wifi was back

thank you to OP. saved tons of money

Thanks for the guide it really worked for me. I've got the international and domestic unlock. The only problem is I'm using an AOSP ROM, so whenever I restart the phone it doesn't connect to data because it goes back to lte, is there anything I can do so I don't have to go to hidden settings to select WCDMA only every time I restart the phone? Like a build prop setting or a script? Thanks in advance.

My S4 came with NAE rom and I followed this post to downgrade the modem to MDC. Now I want to root the phone and unlock WiFi tethering. After searching so many in the Internet talking about rooting and unlocking WiFi tethering using different rom like NAE, MK2 etc. I somehow question myself which rom my phone is using now. In the 'About device', it shows Software version is L720VPUAMDC but the Android version is 4.4.2. (I know Android version for MDC rom is 4.3). Would someone able to tell me which rom my phone is on now? either NAE or MDC. What about bootloader? I am totally confused.

The version number you provided SPH-L720T the T at the end tells you your phone is tri band, so can't be unlocked with this method, and most likely never, since it's Sprint spark technology, but who knows? there are smart people out there.

Hi guys, I have a Spring SPH-L720 rooted running google play edition 4.4.4. I'm trying to unlock it domestically so I can use it with my verizon sim card. I was running modem version NAE and I was able to sucessfully downgrade it to MDC (downgraded modem only). I then followed the link by posted adol.ivxx: http://xdaforums.com/showthread.php?t=2703955

on how to domestically unlock NAE version S4 which it states to downgrade the modem to MDC and the do am global unlock by following this link: http://xdaforums.com/showthread.php?t=2415587 prior to domestically unlock. When I enter the code ##3424# in the phone dialer to select the Quailcom usb settings, nothing happens. Smae thing with ##3282#. The code I found that it works is *#*#4636#*#* which it takes me to "testing" screen (phone info, battery info, usage stats, Wi-Fi info). I assume that the reason why the other codes are not working, is because the are to be used with previous versions of Android. Can someone please point me in the right direction on where to find the codes that work with my version of android so I can globally unlock and the domestic unlock?

While alanwatt doesn't have Wi-Fi and sound problems, I do, after implementing the GSM-unlock method semi-successfully. I found that installing a Cyanogenmod helped with the Wi-Fi, but I still don't have any access to sound or microphone usage on my phone.

Could you briefly explain to me what the problem is? I've been looking for a solution for some time. Most recently used odin to completely return to all stock, but was still unsuccessful in restoring sound functionality.

After doing some reading, there are posts out there and online articles that confirm Sprint using CDMA just like Verizon therefore I should be able to use my Sprint S4 with my Verizon sim card as long as I unlock it, right?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] duckgrits14:
FIXED:

Used odin to flash the latest (NAE) Firmware found at http://xdaforums.com/showthread.php?t=2338919

This resulted in my sound/audio systems functioning again i.e. I can make calls/use video/etc.

If anyone uses this method to GSM unlock and finds issues with Wi-Fi and/or sound, flashing to NAE seems to be the best fix.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
I don't know what articles you read to lead you to that thought . you cannot use a Verizon Sim on a Sprint GS4. Both are CDMA but the sims you pop in from these two carriers are for LTE. And when you perform the unlock its ONLY for GSM Sim cards. To use a sprint GS4 on Verizon you would have to flash the phone which would only give you 3G because sprint and Verizon use different frequencies for LTE which the Sprint GS4 doesn't support.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] ROMANTiC KiD:
You will never be able to get LTE because of different baseband which are unsupported. 3G/H+ is the closest you will get to high speed data if using a different carrier.

post- test of the sim unlock and results

Device. Sph-l720

Followed the procedure as posted, downgraded successfully to MDC modem, used the unlock program , worked fine with an international sim, up until the step where you flash back up to the MF9 modem. After flashing I get absolutely no sound from the device. Dialer crashes. Skype crashes. The phone occasionally freezes.

I tried using Odin to flash back to MDC, nothing. Tried reflashing the whole set aka modem rpm nonhlos.bin, the sbl2/3 , nothing. I can get to my recovery , Phil's, and download mode. All attempts to flash a ROM with a working kernel so far have yeilded the same result.

Do not install lollipop yet. If you have the sphl720t and unlocked the sim card by downgrading the modem, I'm not sure if it will relock it.

I need to get another 720t and try the update and see what happens. But if this is your daily phone I don't recommend it. Also, lollipop makes your battery drain faster, and there is still some bugs in it.

Sprint galaxy s4 unlock issue

Hello guys,

First post here so bear with me if I'm doing anything wrong. I used this method to unlock my Galaxy S4 and it worked perfect. The only issue I had non related to this procedure was my old Sprint phone number was showing in the settings. I did a reset using ##72786# and it removed my unlock. I did the procedure over again making sure to go through all the steps including downgrading the modem to MDC. All seemed to have gone well with even the unlock tool showing completed but when I pop in my GSM sim card, I have the little red ˛ by the signal. Also the invalid sim notification disappeared as it should when its unlocked but again, no signal.

Any help would be appreciated. Thanks in advance!
