UICC unlock remains as is... It won't disappear when unlocked
[Sprint Samsung Galaxy S 4 Android Development] HeXacTa:
finally I figured out a way around to get data working on GSM/WCDMA on my device.

1. edit your build.prop and add the following parameter:

ril.sales_code=LOL

ro.csc.sales_code=LOL

2. access your APN using [MENTION=2684188]autoprime[/MENTION] shortcut trick here: http://xdaforums.com/showthread.php?t=2377228 and edit/add your GSM carrier APN and select it

3. to activate GSM/WCDMA mode, download and install "android data tools" on https://www.dropbox.com/s/2ln209o53tiu6ol/PhoneUtilss.apk courtesy of [MENTION=1573711]Viper32[/MENTION] on http://xdaforums.com/showpost.php?p=41195590&postcount=3

- open the tool, go to Universal Tool and Open *#*#4636#*#* Menu.

- Scroll down, look for "Set prefered network type" and change "CDMA only/CDMA Auto(PRL)" to "GSM Auto (PRL)" or WCDMA preferred/only if you want to force 3G/HSDPA

now you can have data connection on GSM/WCDMA and can swap back and forth with CDMA without having to reboot and also if you turn on mobile hotspot when change network it works continuously..

===

edit: or simply use this hiAPN app for automatically add APN accordint to your SIM card carrier: https://play.google.com/store/apps/details?id=net.hidroid.hiapn.ml

Pls try and report if this works on you.. :o

Help Me Please ??!

I am having this phone unlocked and I am getting a OTA

The Question is :: Will the OTA lock the phone again the phone is not rooted and stock MDC

I had this phone in the past and had no problem to upgrade it through Odin with full .tar ROM

This is why I am wondering if the OTA will lock the phone ???

any quick answer would be appreciated :confused::confused:
[Sprint Samsung Galaxy S 4 Android Development] agapedisciple:
Get FOTA.apk - search the xda forums. You must have root access. Install it, then make it a system app using the system/app app on the play store. The OTA notification will be gone! ?
[Sprint Samsung Galaxy S 4 Android Development] agapedisciple:

[Sprint Samsung Galaxy S 4 Android Development] agapedisciple:
Hard to say without looking at the original DFS programming instructions. I asked the OP in PM but haven't heard back yet.

You do have two other options though. You could install the FOTA.apk and block the OTA since you've got your root. Or upgrade using ODIN with a ROM posted on xda. That way you'll protect your root too. But you still may lose the SIM unlock with the second option.

Hi i wanted to ask , if i ll be able to downgrade the modem on a s4 that is on 4.3

i have purchased one for international usage and its still in shipping , forgot to ask the android version :P

thanks
[Sprint Samsung Galaxy S 4 Android Development] vMAC:
So just to confirm. I currently have a international SIM (Orange Israel) and I followed this guide prior to bumping up to MK2. Right now when I go into settings I can see the ICCID of the my international SIM card, I get no "unkown" indicator. So are you saying that my phone is unlocked? I when I switch to GSM, I get no bars, only a red x on top of the bars even when roaming has been setup. Is this normal? No way to force the phone to make a call on GSM? I want to test this SIM BEFORE I get to Israel.
[Sprint Samsung Galaxy S 4 Android Development] shokuhawan:
So this method works even you upgraded to Mk2 baseband? I'm in another country outside US and use GSM carrier, i'm afraid to do an OTA upgrade to Mk2 because it may relock Sim again.
[Sprint Samsung Galaxy S 4 Android Development] agapedisciple:
I'm curious about this too. I've got an international SIM in my phone right now and I get the same thing. Not sure what setting to put it on. I can go on the DFS and change what pref mode it's in... maybe that's the key.

BTW, I'm sure the international SIM I have can make calls from the US in an unlocked GSM phone. Does yours?
[Sprint Samsung Galaxy S 4 Android Development] vMAC:
No I'm not sure, just got it, so I'm not entirely sure that is why I need to test it.

can anyone plz tell how i can downgrade the Mk2 modem to MDC to unlock this phone ?

would be grateful
[Sprint Samsung Galaxy S 4 Android Development] desiwizard:
I followed these steps

1. Downgraded to MJA Stock firmware through ODIN (Full Firmware) and rooted it

2. Flashed MDC Modem only through ODIN

3. After unlocking flashed back to MJA Modem Only

Regards
[Sprint Samsung Galaxy S 4 Android Development] lord dredd:
I think i ll try to flash MDC modem directly

and will unlock and then flash mk2 modem , all via odin

should work similarly as mja and mk2 are more or less similar

Glad to know that you succeeded. Which ROM and radio you are on now?
[Sprint Samsung Galaxy S 4 Android Development] pirvu_daniel:
I am now on the stock rooted ROM and baseband NAE.

I have a new question. How we can we activate the phone? My phone can't do this online and it says that I must call to a phone number. I am from Romania and I have bought the phone when I was at a congress of gastroenterogy in the USA. Sprint activates the phone also if have unlocked the phone? First time when I have unlocked the phone it don't demand activation. The phone is working perfect but it demands activation two or three times per day. It is annoying.:(
[Sprint Samsung Galaxy S 4 Android Development] desiwizard:
There may be some sprint native system apps which are checking the phone for activation on sprint network. You may try using titanium Backup to disable some sprint apps. Make sure you do not delete or uninstall them. Just freeze it, so in case if you get any errors you can DE-freeze that.

Root Browser also freezes apps.

Its hit and trial by looking for some wizard type apps.

[Sprint Samsung Galaxy S 4 Android Development] pirvu_daniel:
Sorry for my late response. I had some busy days at work.

I have made the update and I have lost the unlock. I didn't manage to downgrade the modem with SPH-L720_MDC_Modem program until I have flashed the phone with the NAE tar file which was posted some pages behind.

The method for unlock is the same from the first page. Another problem was to obtain the MSL code.

After I unlocked the phone I have flashed the phone again with the NAE tar file and I have rooted the phone.
[Sprint Samsung Galaxy S 4 Android Development] TheNinja370:
Just wanted to report that my Sprint Galaxy S4 is working great in Singapore.

Details:

1. Used process described in op

2. I am rooted, running CM 10.2

3. Voice and data work flawlessly

4. Sim Card was plug and play, no futzing around with any settings, etc. Inserted card, activated, done.

The only thing I noticed is that my network still displays as "Sprint", and my U.S. number is also displayed instead of the local number on the sim. With some quick tests, my phone is definitely using the sim and local phone number. So, all good. APN info is embedded on the sim I purchased, so just plug and play.

Initially, I had Sprint International roaming turned on for emergencies, but cancelled it because the sim was working. At first, I was freaked out thinking that I was actually using Sprint's roaming and their exorbitant prices (due to my US number and Sprint network name being displayed), so I was relieved when I cancelled it.

Thanks to the devs, I am able to use my phone the way it was intended with no hassles dealing with my carrier. Great job!

Downgrade and upgrade

Hi, I am on MK2 trying to unlock my sim for use with international GSM carrier. I am on 4.3 now and I know I have to first root then downgrade to MDC. After that is all done and I am all unlocked, does anybody know if I upgrade to the new software (I believe it is called kitkat) will the unlock be removed after that? I have been reading on this thread but have not really seen anybody do this just yet. I read some lost their Sim unlock after upgrading back to their original modem.

I want to give it a shot, but don't want to do it if it will not be possible to keep the unlock after updating to new software.
[Sprint Samsung Galaxy S 4 Android Development] MosesTheTool:
I was on MK2, unlocked simlock, went back to MK2 and the sim lock works. Then flashed the Sac's rom (android 4.3) and still have sim unlock. But I am not sure about Kitkat because we have to update to NAE. Waiting for an answer about that as well.
[Sprint Samsung Galaxy S 4 Android Development] MX51:
Hey moses did you have any trouble rooting on MK2? I have been reading quite a bit but some people say that the CF Auto Root may brick your device if you are on MK2. I was getting ready to do the root and unlock last night but when I read that post about someone rooting their device I completely got discouraged.
[Sprint Samsung Galaxy S 4 Android Development] MosesTheTool:
I had no issues what so ever,

I rooted, then downgraded to MDC, then unlocked sim-lock, then upgraded to MK2 then flash Sac's.

I can try to find the guides i used if you need them,

the sim-unlock video: VIDEO HOW TO SIM UNLOCK

and i used this file: CF-Auto-Root-jfltespr-jfltespr-sphl720
[Sprint Samsung Galaxy S 4 Android Development] MX51:
Awesome man, thanks for the info. I was really discouraged last night when I found out I could be very well on my way to bricking my device. Also, when you do any of these procedures, did your device completely reset? (meaning did you pretty much start off like if you had just gotten the device?)
[Sprint Samsung Galaxy S 4 Android Development] MosesTheTool:
Just be careful, and follow instructions patiently.

My device was Reset before i began, so I can't really tell you. You should always backup your stuff before doing things like these, also, right after you root and install recovery, make a backup of your device and put it on your computer, i had so much bad experience, it's worth the 5 minutes.

Good luck!

Well here is the list of knox files if you cannot find in folders specified look in /system/priv-app as structure is changed in 4.4 based roms. Use root explorer to delete these files.
