I have the SG S4 Active (i537) for AT&T, baseband I537UCUAMF3 and tried every method I could find for unlocking and acces to ServiceMode, but nothing really worked.
After reading several post on xda and other forums about this phone, I found this thread: http://forum.xda-developers.com/showthread.php?t=2514607 and done the steps described in these posts. I guess (tried with a T-Mobile not active Sim) I was able to unlock the phone; before doing this method I was getting the message "enter network lock key" when inserting the T-mobile SimCard, after that the phone just boot-up normally without asking for the network key again. I said that I "guess" the phone is unlock because I can't be 100% sure because the SIM card is not active (old one). I will try with an active SIM card and update the info.
In any case I am not responsible for any damages that this method could do to your phone, and I'm not affiliated in any way with the developer of the app.
Please read the posts provided about this thread before trying this method.
Samsung Galaxy S4 Active (I537) AT&T
Baseband: I537UCUAMF3
Android 4.2.2
Note: Before trying the unlock method I inserted a Straight Talk (AT&T compatible Sim card active) and worked like a charm, so if you're using Straight Talk (AT&T compatible Sim) you don't need to unlock the phone.
Update: I tested the unlock with an active T-Mobile SIM and worked perfect
If you can't access Service Mode try using SamIOTA app in playstore, worked for me! (tip: tap on the two options for several times and it will access the app!)

Recently got a G1 off a friend as tempory fix until my replacement X10 arrives.
Phone is currently locked to T-Mobile and I don't have an active T-Mobile sim card.
I've been following the guides on rooting it but I've ground to a halt.
I've flashed the ROM back to the earlier T-Mobile ROM (i.e. before the exploit was patched) as per the guide, but now, because the sim card in the phone isn't active, I can't log in to my google account to get onto the actual handset.
Any possible work around for thid?
Before I flashed it, the ROM that was originally on it allowed me to skip this login step and connect via my Wi-Fi.
I hope you do know, unlocking and rooting are two different things.
Yes.. hence I listed flashing, rooting and sim unlocking as 3 seperate proceedures.
http://forum.xda-developers.com/showthread.php?t=452316 should help you
Although if you sim-unlock it (since you're not a T-mobile customer you would have to buy a code from numerous ebay/craigslist sellers) you could just use your simcard to go through activation (look in the big APN thread for your settings)
That thread is big help, thanks!
Still stuck though, I've got DroidExplorer and all the other software needed installed, however I need to get USB debugging enabled on the phone.
I cannot do this without gaining access to the phone itself.
Going round in circles here!
No one?
i heard at many places that if you download an app from market named "galaxy s unlock" it will unlock any galaxy s model.so here's what i wana ask. My brother recently bought an AT&T captivate from US..he is bringing it here to india..i was thinking will this "galaxy s unlock" work in my device to unlock it..it is on android 2.1, if the app works then can i download it without a simcard and in offline mode with WIFI?? coz i dont have an AT&T sim card!

I honestly do not know if you need the SIM card or not to access the market which will allow you to get the "Galaxy S Unlock" app. I have tried the "Galaxy S Unlock" app before but I could never get it working (with stock FW and Stock FW + Root). Im pretty sure that you cannot use that app once you update from Stock FW to Stock FW + JH7 (the original "GPS fix" back in Sept). However, the way I got my unlock code was the following steps:
1) Go back to complete stock FW using the following link:
http://forum.xda-developers.com/showthread.php?t=731989
2) Root the device using the following link:
http://forum.xda-developers.com/showthread.php?t=739304&highlight=click+root
3) Get your unlock code using the following link:
http://forum.xda-developers.com/showthread.php?t=761751
This may be the long method but this is the only way I have ever gotten my unlock code. But then again, once I got my unlock code, I never tried to get it again. The above steps that I took did not require a AT&T sim card at all.
I hope that helps.
Hey! Even i got this phone from United States to India and now even i m in a fix that how do i unlock. please tell me did u manage to unlock the phone?
Hi All,
I've trawled through this forum for quite a while and haven't yet found any answers or similar cases to the issue I'm currently having. Here's a summary of where I am at the moment with my i9305 LTE:
- Got a i9305 locked to EE.
- When EE quoted £20+ and 10-20 days for unlock I started looking at altenatives.
- For one of the alternatives, I flashed to get root and I believe I lost my IMEI. I didn't have an efs backup and was unable to restore via stock flashing.
- Luckily, I had a screenshot of my settings so I re-wrote my IMEI using QPST.
- Decided to go for the legit unlock this time so called EE and paid for the unlock code.
- Pre-root, when I put in my unsupported SIM I would get a prompt for an unlock code, but that doesn't have anymore. While waiting for the EE code, I found that when I inserted the unsupported SIM, I would sometimes be able to connect in very specific locations (e.g. certain places outside the house). Wi-Fi works perfectly.
- When the unlock code came, I attempted to enter it by getting to the prompt using "#7465625*638*#". Although, when I enter the code here, it does not accept it (I have an unlock and an unfreeze code, neither work).
- I have trialed the SIM in various other phones and have had no problems with signal at all, the problems arise when I place the SIM in the i9305.
- I have tried changing the modem, so far no luck...
No idea how to go about fixing this... At the moment I can't use it as a phone.
Here is some more info:
Samsung GT-I9305
Nameless Rom 5.0.2
Baseband: I9305XXBLL3
Android Version: 5.0.2
- Should I keep trying different Modems?
- I've tried to verify whether phone is locked or unlocked, but *#7465625# doesn't work, do you know any other ways that I can diagnose sim lock status?
- Will different ROMs or kernels help?
Thanks for any help!
-- UPDATE --
Have flashed back to stock 4.1.1.
I attempted to sim unlock via the *#197328640# approach, but wasn't able to get it to work...
My current next hope is to try and restore my i9305 to the point where it asks for a code to unlock upon entering a new SIM again... Would really appreciate any help, Thanks!
I've still not been able to fix, but will update when I do in case it helps anyone else :good:
Ugh, I am having so many issues with this at the moment. One of those things being that I am using T-mobile as my carrier. I'm stuck on 4.4 at the moment, and need to update it. But, will that relock the phone? How do I re-unlock it if that happens? I've already read that I can't flash the phone to T-mobile ROM, but are there any custom ROMs that you would recommend [I do actually use the S-pen, not sure if any have been updated to where that can still be used.] Lastly, is there any way to get mobile hotspot and tethering to work now that I am using tmobile?

I never tried this Rom.
T-Mobile Alliance Lollipop Rom on ATT Note 3
http://forum.xda-developers.com/note-3-att/general/t-mobile-alliance-rom-att-note-3-t3065127 I don't think you would have to worry about any of this as you are using T-Mobile " After the phone came up, I went to settings..general..applications...running .... and found every Tmobile app and cleared cache and disabled them. The real important one here is the Visual Voicemail. Otherwise it will keep on trying to contact Tmobile and then you will get text messages saying there is an error. Thanks @sapps
Wifi Calling is throwing a sim card error (as you would expect). Only problem is it is shown in status bar and lockscreen. I'm sure there is a way to hide it or disable it. I just haven't had a chance to figure it out."

But it's the N900A, so it's the AT&T version. Won't that brick the phone if I put the tmobile ROM on it? That's what I've read in other threads on here anyway. [Honestly I shouldn't write when I'm tired, or I would have explained this better.]. Basically, I bought an unlocked AT&T phone. A Note 3 to be exact. It's stuck on 4.4 but can upgrade to lolipop. Nothing I try will let me upgrade the normal way. I'm not sure how to upgrade it without relocking the SIM card somehow. Or is the simcard already semi-locked and that's why it's giving me the error? I also can't even find a AT&T specific rooting guide for this phone. I saw every other carrier except AT&T, does that even make a difference? And are there any ROMs that can return S-pen programs after I install them, or should I just stop at rooting if I want that? If so, I just really want to upgrade to lollipop and root the phone. I would like my mobile hotspot and wifi calling to work, but I suppose I can make do with hangouts.

It won't brick you phone. It's a T-Mobile Rom that's been ported for AT&T Note 3. After you flash the Rom, you have to Odin the N900A_OC1_ALL_Other_Stock_Partitions.tar.md5 using Odin's PDA slot. As far as rooting what you have now, just use Towel root https://towelroot.com/ (install on phone like any other app) and click "make it rain". Install Supersu, busybox and Safestrap. OR use Kingo Root http://www.kingoapp.com/ (Kingo Root will install supersu for you). The reason it won't upgrade to Lollipop is you have a T-Mobile sim card in it. It needs a AT&T sim card (I have AT&T and can't upgrade mine unless the sim card is in the phone). If you just want a rooted Lollipop Rom, but it's AT&T http://forum.xda-developers.com/showpost.php?p=59666958&postcount=2 You know since you're on T-Mobile you have to go into settings>more networks>mobile networks>access point names and change it to T-Mobile's APN. I would just root it and put the T-Mobile Alliance Lollipop Rom on ATT Note 3 on it. I gave it a try yesterday and it does have T-Mobile apps on it, just not for me. Just remember to change the APN to T-Mobile's ( just write down the one you using now).
Hello,
I have an SM-N950U from TMB which was purchased direct from Samsung when it was just launched after the whole debacle of the Note 7.
Phone has been working fine on TMB this whole time. Today I switched to VZW and attempting to have the phone unlocked.
I tried to use the Device Unlock app on the phone, with no luck. It fails when I try to Permanently Unlock the phone.
I called TMB for assistance, they said that the manager has tried to process it manually and has been unable to do so after multiple attempts. Escalated to higher support who got on the phone and said she's unable to help and does not know why it is not working. Said she will be escalating to a higher support group, but as of yet, nothing from anyone.
Is there any way of unlocking this phone without TMB?
I've attempted to flash VZW via ODIN, both U and U1, with no luck. I also tried the U1 XAA and still the same thing, I get a message "Network locked SIM card inserted".
Any help would be greatly appreciated as I am at a total loss and want to continue using this phone as I've been, just with VZW now.
Side note, maybe it's failing because the phone is already unlocked, just doesnt work with VZW? Not sure if thats a possibility, but is there any way to check to see if the phone is in fact unlocked or not?
