AT&T Galaxy S4 boot loader help - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Trying to switch my Galaxy s4 (at&t) to straight talk service. I love downgraded to mk2 and rooted /
Super User as well as Safe Strap. I'm on mk2 now and just got my wifi working. I don't know how to unlock the boot loader or what but it's in the stock slot. I messed up the default but I just want to be able to switch to straight talk.

Ended up switching to a t mobile sim card. I figured since it's a att phone to use the att sim card.. but I tried the t mobile and getting some service but very little. ST is telling me a tower near me is down to give it 24 hours but I feel that's a goose chase lol I've used a t mobile sim card in the exact spot I'm in and worked fine. It was in the note 2 from Verizon fully unlocked though.

I have a at&t locked s4 on straightalk now. No need to root unlock or anything just the at&t compatible sim from them and adjust apns. I can't advise on the tmobile base for st since there coverage is horrid in my area but if you do use the at&t the apn I use for my s4 and my gf s4 is as follows
apn:tfdata
port:80
mmsc:http://mms-tf.net
mm proxy:mms2.tracfone.com
mm port:80
anything not listed above was left as either not set or whatever the default was when creating a new apn. I have no issues with data or mms using this apn on either phone. Hope that helps

Well they told me a tower was down for t mobile yesterday and they said 24 hours and it's still not hardly working. I can only use my gs4 on my couch with my hand near the window. About to call them and get I in their butt. It's not my phone is the apn settings or something on the ST end. Will update after this long as call

Unless I am mistaken the apn has zero to do with reception. Apn's are for your mms/data access. I have never come across a phone where the apn had any effect on the actual cellular signal.

[Q] S4 MF3 Sim unlock??

I've for a AT&T S4 I337 with the MF3 update. I have already managed to root it. Is there any way to unlock the sim?? I have searched. Tried to get to the service menu and it does't let me do anything. Can I flash another rom or do something so I can unlock it.

Seeing how you are on the MF3 currently there is no way to flash another rom or custom recovery, your best bet would be go through att to get the unlock code.
But it won't even let me get into the service menu. I tried the codes and process they say online and it does nothing. Can someone explain why it won't budge and how and when it will be fixed?

The service menu unlock was disabled in MF3. You have to get an unlock code from your carrier or another service.

Theres not even a place to enter an unlock code. I cut my Straight talk sim with the proper tool and inserted it and it didn't even recognize it. Still says "no sim inserted." Going to try to buy a ATT straight talk sim from the Straight talk website next.

I ported my # over from AT&T today to Straight Talk. At first it didn't like the new sim card, but after my # was ported and a few reboots the message didn't come up anymore. I now have phone & data service running on it, even though I was still under contract for a previous device (S3). I called AT&T and after a lengthy call, they said I didn't need an unlock code if I was getting service OK from Straight Talk. My old APN info is still there for them along with the one I created for 'ST'. I have no way of deleting the old APN, and who knows where, or if I'll get updates from. My only other option was to get the Google Edition S4, but I payed full price for the one I got now. Hopefully the bootloader issue will get cracked before long and I can get this ATT crap off my phone for good.
Network lock
I want to share something, could get passed the first screens all the way down to the network lock menu, no sha off options.
Haven't seen any posts regarding this.

Hey,
I did watch that video, but I am not sure how to get to that "Samsung Service Mode" Screen . Can you tell the steps please.
Thanks.
Ok, isnt that region lock thread just for Galaxy Note 3s? and on MF3, doesnt seem like the service menu will come up at all, so kinda curious too how people are making that work.

Hey did you guys talking about region unlock or carrier unlock?
Can you please share steps you followed, it will be a great help.
Thanks.
It's been mentioned that region unlock has had a positive affect on the Sim unlock.
However Sim unlock and region unlock are totally different from one another.I used the free unlock method when I was MDL and only used the region unlock with MF3 .will I ever really know if the region unlock worked?probably never.
I am still Sim unlocked

galaxy s4 sgh I337 at&t unlock

Hey there, I have a samsung galaxy s4 sgh-i337 locked to at&t.
I bought an unlocking code from an ebay user.
it doesn't unlock my phone, it writes: "unlock request unsuccesful". I tried to use the defreeze code and then again the network code, still nothing.
I was referred to a guide that suppose to show me the "service mode menu", by entering *#0011# . so service mode goes on when i put that number in the dial pad, but then I suppose to do 'menu key'->'back'->'menu key'->'key input'->'1', but after I do that nothing happens, the service mode menu with all the options doesn't pop up, it stays in the same page of the service mode. somewhere down on the ServiceMode page it writes "Service:Limited". what should I do?
Talk with an at&t rep or chat online and indicate that you will be traveling and want to use this phone there and they'll give u a unlock code..

Someone... Help.. please
no Mega genius here that can solve my problem?
same boat here man, this is a new problem since not everyone has 4.3 yet. Att won't even give me the unlock code since they changed eligibility few months ago to "only off contract or fulfilled contract phones." I've read one person saying the eBay unlock code didnt work on 4.3 either. And the only success i've heard is another post here on XDA saying they unlocked 4.3 using the regionlockaway app, but they apparently Odin flashed 4.2.2, did the regionlockaway while the phone had no sound/wifi etc., then Odin flashed 4.3(locked again), then flashed 4.2.2 odin again, regionlockaway'ed, then odin'ed 4.3 again and the unlock stayed. That sounds ridiculous and is not an exact science.
So i'm done with At&t's phone slavery and switching to T-mobile on a nexus till the Xperia Z1 is out. I thought this was the future.

If you have another $20.50 go to Myhoian's website it's unlockcode247.com it'll take about a full day or over 12 hours usually but not longer than that he's never failed to unlock any of my phones.

My carrier said I was qualified to do the unlock. How are these services? Paying that much money on a limb sounds sketchy and most endorsers seem to be part of the sketchiness. Anyone else have experience using the only sites?

I337 stock, unlocked, rooted

S4 no signal...Help?

I finally got around to unboxing my S4 and foolishly took the update to 4.3 last month. I managed to root and install TWRP,
then sat it for a month till the battery arrived (Zerolemon 7500).
Okay, i loaded both Hyperdrive RLS15 and ShoStock..... phone operates fine, but when I insert my SIM,
it does know it's rogers, but NO SIGNAL.
Modem issue? I'm frustrated.........back on my S3 now.........
HELP??
Thanks Guys
If Odin the stock firmware. I believe you can get it at sammobile.com for the i337m which you appear to have. If you still have problems it's probably hardware related.
Also, make sure your apn is correct for Rogers

Google Roger apn settings. Check those against what you already have. You might have to create a new apn or edit what you have

(QA) Flashing T-Mobile rom on Verizon Note 3 Retail WIFI Calling

Does anybody know or has had success flashing a t mobile rom, whether it be stock or customized rom, on a retail Verizon note 3?
I've read reports that flashing using Odin will brick...
​But how about using safestrap.
The reason why I want to, is because I would like to completely switch over to tmobile from Verizon. But still keep my phone...
As well has anyone had experience with getting wifi texting/calling to work on a Vz Note 3 retail?
I wish for this thread to be a place where devs, users are able to share and maybe find a solution. Any help or advice would greatly be appreciated
I did flash a t mobile rom on my verizon note 3. I used safestrap. I was getting errors about wifi calling and it would give me a SIM card error every now and then. But over all it worked fine. Just add Verizon's data info in so your text messaging will work.
Cant get tmobile to work
Can someone please point me in the right direction........i am just trying to get my VZ note 3 to get tmo services to work, but no matter what i do, nothing works...
I have tried on the stock rom before rooting or anything following these steps listed in OP== NO DICE
I have rooted, installed safestrap 3.75 b4 and tried the steps again===NO DICE
I have installed a custom rom, specifically jasmine rom 2.0( which requires to flash the NC2 modem afterwards, which i did successfully) in hopes that that would help and====NOOOO DICEEEE
i can't access any service menu listed in this whole WEBSITE, none will work, not even an app from the play store that executes them....
I just keep getting that stupid INVALID SIM error and the bars indication stay blank and nothing happens.....WHAT THE #&@% AM I MISSING????
I HAVE NEVER RAN INTO SO MANY ISSUES BEFORE, im not a newbie in flashing stuff or anything like that, been using XDA since teh Windows Mobile days in HTC's prime, but this has be off the wall.
ANY HELP at all would be appreciated....since im the only asswhole that cant seem to have tmobile work on the VZ Note 3.......

I did flash a t mobile rom on my verizon note 3. I used safestrap. I was getting errors about wifi calling and it would give me a SIM card error every now and then. But over all it worked fine. Just add Verizon's data info in so your text messaging will work.

No I have not. T-Mobile is not in my area to try this. Sorry.

I went in to the Mobile networks Setting and added the APN info for Verizon.
Has anyone ever tried flashing the T-Mobile modem to activate the WCDMA 1700 band? Is that's what's needed to activate this band or is there more to it? I know wih LG devices, by flashing the complete software of a different carrier changes the band settings as well
I'm assuming no one has any interest in doing this? WCDMA 1700 is needed for HD voice for T-Mobile....

If it's the G930V then flash the G930U firmware onto it. Should work.
Was told that was possible
