[Q] Need help with Sim Unlock - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi folks,
I am familiar with the i9500 s4 which I own and mess with. However I also acquired the SGH-I337M model which is locked to the rogers network and I'd like to just unlock the sim.
I ended up just purchasing the unlock code for the i9500 from cell unlocker as it was still early days with the S4 and other methods found on xda weren't working..
Can anyone provide me with a known working guide to sim unlocking this model?
Also, will flashing a custom rom - TW or CM based unlock the sim?
Thanks for any input.

This might be what you are looking for:

However, others that will post that might not give you this warning...
Read through the entire thread before you touch anything! There are possible risks with the method and you need to read about them so you can make an informed decision about if you want to try it or not. If you choose to not read the entire thread or take precautions, it's up to you.
Searching through the "general" and Q&A forums for "unlock" should show you others threads that you might want to read as well. Good luck.
Oh, and flashing other ROMs will not sim unlock the phone.

Thanks,
All seems like different variations of what to select in service mode.. I tried similar service mode steps with the i9500 and never got anywhere so just bought the unlock code... Will keep digging..

Canadian (fido) S4 and new ROM install ?

Hi guys, sorry for asking this, I know it is probably mentioned but I have spent the last 2 hours in this forum for various interests, including my galaxy gear and my eyes are hurting right now...lol
So before I attempt something and make a mistake because I missed something, I figured I ask straight to the point...
I am on the latest 4.3 OTA update on my fido S4.
I am interested to possibly flash the Rom to another one that is clean (without all the stock apps) and gain access also to bluetooth tether which is right now not available through fido.
If, this is an option with another ROM (which I am hoping it is)
So is a ROM available ? That can be flashed over the latest update ?
I found some threads but they were referring to already rooted phones etc...I am just not sure where I stand with the latest update, so I would really appreciate some info.
Thanks.
I have a Fido S4 on MDJ(4.2.2). I rooted and unlocked(using RegionLock away). If I flash a newer rom will I see a significant speed difference or performance boost?
Thanks

I'm pretty sure you can not unlock phone using region lock away, but on MDJ you can with secret menu, provided you never updated to mg1. Besides 4.2.2 Fido and before, was not region locked at all.
Maybe now with 4.3 it is. Did not check and can't be bothered looking for European sim card.
To answer main question. No! If you factory reset phone you will, but that's only temporary, which is why newbies keep saying it's faster and better with every firmware.

I am not the first to claim I unlocked with RegionLock away. I inserted a T-Mobile sim and a Bell sim, and it did not ask for an unlock code. Before I ran RegionLock away, when I inserted a T-Mobile sim, it did ask for unlock code. Also, many people say the secret menu unlock doesn't work for Fido and/or screws up something.
Oh, what's that formula for POST COUNTS and NEWBIES again?
Hey guys, checking in again...
Sorry for the question, don't want to be flamed but there are A LOT of posts about different versions and I really do not want to screw up.
So :
Canadian fido S4 on 4.3 over the air update. Can I still root ? Possible link to the correct method ?
Any ROM available that is clean and would re activate BT tethering ? Link if any ?
Sorry guys, I am not lazy, just dizzy reading all the threads and trying to short them out between versions...
A mistake would put me in worse situation and 2 simple answers from anyone that knows would be greatly appreciated.
Thanks again.

[Q] Network unlocking my I9500 and knox

rodtakular said:
Hi guys, I wonder if I can get some help unlocking my I9500. I'm traveling to US next week and would be acquiring a t-mobile or at&t prepaid sim to use the the phone, so I need to unlock it.
First of all, I have verified that my phone is locked to accept sims only from my carrier.
Second, yes, I have tried the methods explained http://forum.xda-developers.com/showthread.php?t=2282683 , but I always get:
MENU NOT EXIST
PRESS BACK KEY
Current Command is 111
If relevant, my s4 is using android 4.3(official from my carrier), the baseband is I9500BUEMK1, build number JSS15J.I9500UBUEMK1.
I don't want you any method that may void my warranty or alters the knox flag.
Are there others "not invasive" methods to network unlock my 9500?
If I have to get a network unlock code from some site in the internet, which ones do you recommend that are reliable? would using a unlock code alter my knox flag?
Thank you so much in advance.

Galaxy S4 i337m Telcel unable to SIM unlock via Service Menu

Hello guys, I have been going madness today trying to unlock my gf's Telcel Mexico Galaxy S4 i337m.
I initially tried from the stock branded rom but I couldn't pass the first page in *#0011#. So I decided to debrand it using a Samsung stock fw I337MVLUEMK6.
Unfortunately even with the debranded rom I have gotten the same result, unable pass the first page in *#0011# no matter how many times I would hit back, and the option 1 or whatever makes no difference.
At that point I stumbled upon this thread and I decided to give it a shot, however no go with this method either, probably wasn't even the point of my situation.
So at this point my questions are, is there another method beside buying an unlock code to get this phone unlocked? If anyone of you who has had luck unlocking the phone with this method would pass me it's HiddenMenu.apk, would it work if I sideload it onto my gf's S4?
Thanks
Any help??

You have to flash an earlier modem to either let you get to the hidden menu or that will work with an app called RegionLock Away. AFAIK that's the only way to do it. Do a search, some people have asked and figured it out but i have the I337 so it's different for me.

Thank you for the answer.. I had somehow figured that out but I wasn't sure. On to this thread it is stated that they have achieved to successfully unlock their S4's through Hidden Service Menu with the MF3 OTA fw.
At this point my question is, can I go with the modem_CWM_I337UCUAMF3.zip(7/9/2013)(US) baseband found on this thread and flashing it over the stock fw I337MVLUEMK6 ?
As far as I know the modem_CWM_I337UCUAMF3.zip(7/9/2013)(US) baseband is a 4.2.2 while I337MVLUEMK6 is a 4.3 version, so I just want to make sure it won't brick the device.
Apart from that, the two phones should be identical right? Like I said this one is a i337m Telcel one from Mexico, while modem_CWM_I337UCUAMF3.zip(7/9/2013)(US) should be AT&T right?
Thanks

You can't flash that one, but you should be able to flash one of older ones. You are right in that that modem is for the AT&T one, and that means it actually won't work for you. You'll have to flash one that has I337M instead of I337U. Besides that, you should be good.

Thanks for your reply once again.. In fact as you have said I tried the I337U AT&T version and obviously I didn't have any GSM/UMTS signal, so I went with the modem_CWM_I337MUMUAMDL.zip{5/30/2013}(Mexico) and I can finally get into the Services Menu, I can do the whole unlock process listed here, however once the phone reboots the result is the same, S4 doesn't read any different simcard beside the one it is locked on, which is Telcel.
Any idea? Is there a specific baseband version that does this trick on i337m? Additionally, is there a website where I can find all kinds of baseband versions for the i337m?
Thanks

Hi, im from Tijuana i also have that smartPhone and was having the same problem, what i did and it worked for me was to install this firmware
http://www.sammobile.com/firmwares/3/?download=27549
From sammobile it is the Telcel oficial with JB 4.3 then i put my Movistar chip and it work..
Saludos...
Yeah, there's a new firmware from samsung that unlocks phones by default.
I've tested it with that exact same one.

I did a previous downgrade to 4.2 tho.
Using that 4.2 firmware, and the *#0011# code, didn't work for me.
So, I returned to the stock branded 4.3, placed a Movistar SIM, and boom! unlocked.
Didn't work too good because of the ugly 4.3 Telcel branded firmware, but at least it's unlocked.
After that I decided to install Goldeneye ROM, and the phone was carrier locked again.
The developer told me that a proper unlock method would be needed to achieve unlocking.
I managed to make a nandroid backup of Telcel's firmware, and Goldeneye ROM, and:
- inserted SIM different from telcel to the phone, booted into Telcel's firmware a couple of times and got it working
- flashed the Goldeneye ROM and retained the unlocking.
the only thing is:
if you ever place a Telcel SIM, the lock will return.
So far I've managed to keep it working once (2 full weeks) without problems.
Yesterday I tried to do it again, and every once in a while the SIM lock returns.
-------------
In other news, anyone knows how to flash other ROM than Telcel's and that buggy 4.2 I found?
Every single ROM I try to flash through ODIN gives me an error, and won't let me flash.
I've tried all these with no results:
I337MUMUENB1_I337MUUBENC1_TTT.zip
I9505XXUENAA_I9505YXXENA7_PHE.zip <--- thankfully that didn't let me flash, it was for a 9505 ::V
I337MVLUAMG1_I337MOYAAMG1_BMC.zip
I337MVLUEMK6_I337MOYAEMK6_PCM.zip
I337MVLUEMK6_I337MOYAEMK6_SPC.zip

[Q] Help regarding SM-G900P

Hey everyone, I been looking around the forums here and other sites and have learned a lot of info in pieces but I really need help with a particular issue. A friend of mine gave me a Sprint Galaxy SM-G900P (Galaxy S5) which is (of course) CDMA with GSM compatibility. Im unsure at the moment what service he was wanting to use but I know it is a GSM carrier (US) because he has a SIM he wanted to use. I owe him a favor so I told him I would try. Besides going the route of purchasing a unlock box and unlocking the phone with that, I discovered the SSU apk which SIM-Unlocks the phone. I downgraded the phone from Lollipop 5.0 stock to Android 4.4.2 KitKat (G900PVPU1ANE5) with ODIN. (FYI, i was stuck in download mode with no recovery mode for a week before finally getting one to work, and so happen to be that version that went through)..... I downloaded SSU and it unlocked the phone and I switched mobile network mode from CDMA to GSM Units. (NOTE: it says 4.4.2 and up will not work with USA carrier SIM cards without downgrading the Modem but I have not tried just yet) Im about to Root the phone but here is where my question comes in. I have read of people flashing roms to get their phones to work with certain carriers and other functions. Will rooting help me out at all? I guess IM asking if there is a ROM that I can flash onto the phone to enable the use of whatever carrier he is wanting to use with it. I know thats most likely useful in the situation, but Im awaiting that answer as we type. ANY help would be greatly appreciated ))) Thank you all.
Anyone? :/

S7 Edge SM-G935 Carrier Locked Issue

Hey there,
Long time admirer, not a big poster. More of a reader. I couldnt find anything relevant to my question hence the thread.
So from what Ive gleaned on xda the G935 version can be rooted, my question is can I bypass a carrier lock through a custom ROM or would this be possible just by rooting?
A friend has a G935 that has been blocked to Optus and I was wondering if I could help him resolve the issue and help him bring it over to Telstra by some "black magic" as he calls it.
Thanks in advance for any responses
any suggestions, i have the same issue
Ive tried unlocking rooted phones before myself with no luck. Not sure if its possible without some special hardware and programs. There is a guy on here that has unlocked my sprint s7e and lg g5 before. He hooks up to u remotely and runs a program. I think he charges 15$ and it works 100% till u factory reset. Search "sprint unlock" and u will prob run across a couple of his threads. U can ask him if your model is compatible with his method
He can unlock without rooting your phone
