flash back to original

Hi all, good evening to all.
Need to fix my issue as soon as possible because need to unlock the phone and use it out of country. My AT&T Galaxy S4 (SGH i337) on Android Verion 4.2.2, Baseband Verison i337 ucuamf3, Build # JDQ39.i337 ucuamf3, Kernel Version i337 ucuamf3.
Spoke to AT&T customer service for few times regarding on the unlock code for the phone, confirmed i have the correct unlock code for the phone,and am had tried 6 times by using the same code was provided by AT&T, unfortunately every time i tried keep saying invalid number.
The phone was flashed one time by myself but can't remember which method i used but was found in this site somewhere.
Today went to AT&T store, a very nice sale person told me because the phone was unable to get unlock because it was flashed, he can tell when the phone reboot itself it has a "unlock lock simple" and "custom" word on the screen. He told me the only way to have the phone unlock is have the phone flash back to original by using ODIN 3.0.7 and ODIN Flash of MF3.
Can anyone please tell me above is right programs to have my Galaxy S4 flash back to original? If they are the right programs, where i can get them and step by step instructions to flash my phone.
Need help badly, thanks in advance

You need to know way more information than can be posted in a single reply. The best thing for you to do is read the "pinned" threads in the general and Q & A sections. Those threads will provide you with the information you need to know about your phone and answer the questions you have. If you try to rush things, you will end up with an unusable phone. Good luck.

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.
Sent from my GT-I9505G

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.

To be honest... I don't think it is possible on 4.3 not for free anyhow... limited service is probably because you started out with MK6 modem right? If you really want to unlock it.... try one of the web services talked about in the s4 forum or take it to one of those places in the mall.... they usually charge about $20.... you can pooch the phone if you do it wrong or so they say in lots of the unlock threads....

Besides, the MDL / MK2 type unlocks are for the AT&T versions of the phone (i337), not the Bell Canadian version (i337m).
To do the unlock, I recommend CellUnlocker.net - it cost me 25 USD (now worth about 30 CAD), but they got me the code in a couple of hours, and I plugged it in no problem using a non-Rogers sim.

Am wondering maybe i can use a radio i can flash it with it unlock it and then flash the stock radio rom.
i have did this before on the SGH 2 long time ago.
i remember i had tp downgrade to ICS then flash the custom radio than do the ##0011# trick .
not sure why we cant do this here ????? i can flash another rom on the device i dont see why not i have rooted and TWRP installed on it so its ready for some changes .
Thanks for the advise about the (mall/cellunlock) i might use it as the last resource but for now am playing with this phone i have to figure it out i guess its kinda challenge.

I have the exact same phone. I was able to SIM unlock on 4.2.2 using this video, and flash the modem to enable the AWS frequency for Wind and such. Though this was back with the MDJ modem. I do not think this is possible with the MK6 modem.

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

Need Help - Unlock SIM for domestic use SPH-720T

Hey everyone, I searched and searched, I've been trying to fix this phone for the past week.
I have a galaxy S4 sph-720T from sprint
I am running on the OS slimkat 4.4.4 with modem mk5.
The only fix I can find is using the SSU.apk and running the app.
the app only works with modems under 4.4.2 - so I flashed modem 4.3 (mk5)
I run the App and it says "simlock status: checking...." and it never stops checking!
I try to hit unlock and it says it unlocked it, but nothing really happens and I cant use my SIM card.
Anyone know of any methods that actually work for them? which modems and firmwares do I need? thanks
