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.
Hi,
My friend's S4 GPE lost its IMEI after installing the official OTA from Google. The phone was not rooted or modified in any way before the update.
I've searched high and low but none of the fixes appear to work for the Google Edition.
I've tried QPST, EFS Pro, NV_Items_reader. All of them suffer the same problem. the phone rejects the SPC code. I have no idea what the correct SPC would be or even why there would be one since the phone is not network locked.
The only thing I've not tried is a Z3x box, but it's expensive and I'm not sure it'll work for the GT-I9505G since their site only mentions the GT-I9505.
Returning the phone to Google is not really an option since he bought it while traveling to the USA.
Has anyone else experienced the same problem?
Thanks.
Baseband problem maybe? Take a look this thread too for + info: HERE

Yep, appears to be the unknown baseband issue. Unfortunately the thread you pointed me to does not refer to this issue.
I've searched high and low, there appears to be no known fix for the S4 GPE
Long time reader and tinkerer, but first time poster... This is a two-part thread:
I picked up a cheap used Samsung Galaxy S4 phone, hoping to unlock it and use it. When I received it, it was a SM-S975L, which I can barely find any information on:
Model number: SM-S975L
Baseband version: S975LUDUANB1
Kernel version: 3.4.0-2485535 [email protected] #1 Tue Feb 4 17:57:30 KST 2014
Build number: JSS15J.S975LUDUANB1
SE for Android status: SEPF_SM-S975L_4.3_0017
Product code: SM-S975LZKATFN
Current firmware on my phone: www DOT sammobile DOT com/firmwares/3/?download=28755
Part 1: Custom ROM.
I want to use a Google Edition ROM instead of the bloatware that comes on carrier devices. I'm unable to find a recovery for the SM-S975L, much less a custom ROM though. Is anyone out there that would entertain the idea?
PARt 2: SIM Unlock.
With my sim in the phone, a SIM Unlock code screen doesn't pop up on its own. I typed #7465625*638*# into the dialer and it did finally appear. I was able to successfully sim-unlock it once. But after a phone reboot, the phone was re-locked and the sim unlock code I previously used no longer works. Has anyone ever had this happen? I would like a permanent solution to sim-unlock.
Thanks!
Hi jeredh....I have the same questions as I just ordered this model. Have you solved or tried out anything on your 2 questions?
-JC
I wound up selling it and changing to an S5 Active. No luck at all finding anyone or anything for that phone.
Another purchaser of the S975L here. Thought $249 was a great deal for this phone, but got home and realized that it's actually a really locked down phone. No permanent way to unlock it (unless you own it for a year in which case Tracfone will unlock it), bootloader is locked, no one has developed a custom ROM for it, and the complete tethering framework has been removed (so not even rooted tethering apps will work). It's a good bet that Straight Talk will never update the firmware on it either. That last one is a huge bummer because Android 4.3 is *okay* for now, but KitKat has been out for a while, and Lollipop will be ported very soon. It's fantastic hardware gimped by awful software. A shame really. I'll probably hang on to this phone for a little while since it's a definite improvement over my old iPhone 4S, but I'd like to move to something I have a little more control over.
The only solace I have is that it's easily rootable using TowelRoot.

If you have the unlock code and root, then follow this.
1. install samsung phone info tools from the market. Run it and allow super user access on it.
2. Press menu and go to secret codes, and let it load.
3. Once generated scroll until you find 7465625*638* you should see two. One that says unlock and other says lock.
4. Select the one that says lock. Press it and select "launch 0" on MCC/MNC field enter your carriers MCC/MNC code.(google it if you dnt know it) on the Control Key enter unlock code. Press ok.
5. Select the 7465625*638* that has unlock on it, press launch 0, enter unlock code. Press ok.
6. Hit thanks, device should be unlock with no neet to reboot.
**You need to do this everytime you turn off, turn on, or restart the phone.
Question: Wondering how you got the unlock code?
WAITING
Hello,
I will follow the question, how did you manage to get a code?
I really want to at least unlock my phone to use it,
I know aromerblz is going to make a guide, I have to wait and try it, I am really not having idea what to do to make it work
NO UNLOCK CODE for Permanent Unlock!
.
An UNLOCK CODE for this phone only TEMPORARILY unlocks it.. everytime you power off and phone on OR restart it then it will ask for the code again.. This phone is very well programmed and cannot be permanently unlocked. This is a Straighttalk phone.. its not meant for other carriers.. if you bought this thinking you were getting a deal you were probably wrong.
network unlock
if I purchase a code from a third party and I enter it everytime I reboot does it work on the other network everytime ?
Sm-s975l unlock info
This model is permanatly unlockable through Straighttalk after a 1yr of active service ( If you are late adding time & if your phone deactivates, you must begin the 1yr requirement from the begining )
But good News there are 2 compatible Models of the S4 you can use to Customize your SM-S975L.
Most ROMS are compatible. You will need to have your Device "ROOTED" with Custom Recover Software.
Just my advice use TWRP as Cmod tends to Brick Devices " Just from Personal Experience "
The M919 - Forums General Location
http://forum.xda-developers.com/galaxy-s4-tmobile
The I9505 - Forums General Location
http://forum.xda-developers.com/galaxy-s4
The Most Compatible ROM for the SM-S975L was Created by a Very Talented Developer "The Sickness"
Download V11 4.4.2 & the Mod File. Now Boot into Recovery Flash the Rom 1st following the instructions provided on the download page allow the 1st boot up to complete. Name your phone & all that other fun setup info Stuff. Then reboot into Recovery, & do a advance wipe on Cache & Delvic lol & you can now flash the MOD pack, I recommend choosing the Ktweaker OC Kernel by Ktoonz you can pplay around with the other Mods but be warned the S5 Mods Tend to cause device errors with settings/menu/&keyboard. This rom http://forum.xda-developers.com/showthread.php?t=2683507
DONT LET ANYONE TELL YOU THE INSANE HYBRID 4.4.4 ROM UPGRADE IS BETTER ITS NOT THAT ROM IS BLOATED AND SLOW AS DIRT
There aren many ROMs to choose from icecream sanwich to marshmellow But none as good as "Sickness's" INSANE KITKAT Versions Vary but the Only Rom that comes even Close is SPIKE LABS 4.4.4 GAMING ROM with kernel juicer but its still a bit jittery at times when the GPU is pushed & games are Drawing Heavily On Your Device..
As far as the Baseband is concerned you can remove it and attempt to upgrade it Via ABD pull & push. " Aquire ABD & fastboot files & launch CMD W/ADMIN RIGHTS" & it is possible to use ABD CMDs to remove & apply another Basebamd but this could super brick your Device if it is not unlocked.
Hope this Helps Lot Peeps

I was in the same boat, had an unlock code, it worked one time then after a reboot it would not accept the unlock code. I happened upon this post (while I was searching for the stock ROM to reload on it), and decided "what the hell let me try these steps"....it works. I don't mind going through these steps on each reboot. Infact I made it a bit easier, I installed Shortcut Master (Lite) and made two short cuts, one for the lock and one for the unlock.
Thank you for posting these steps.

Though I do have a question. Are there any ROMs out there that are based on Android 5.x that will work with this? I tried flashing Cyangenmod but the "secret" codes needed don't seem to work at all, infact Phone Info only shows like 12 or 13 codes.

Yes there is.. Any TW based ROM for the SGH-M919 or GT-I9505 works for this phone. CM, AICP or ASOP ROM's do not work as they lack the perso codes for unlock.

Clarification, they do work if you live in the USA as you will still use with TracFone service. But to uses on another carrier you need the unlock code and a TW based custom ROM. Where you got your code?

I got my code from imei-unlocker.com
Like I mentioned in my original reply, the code worked once then after a reboot it was locked and the code was not working. But with the steps that was posted, I am able to use my T-Mobile SIM and just go through them steps after each reboot.
Oh and the best part, the site actually refunded my money cause I was working with them as to why the code stopped working.

Straight Talk SM-S975S unlock
This phone is unlockable by design. The only way Straight Talk gets around the" unlock law " is they offer you a credit towards another phone, my offer was $100. I have a friend that works for Samsung and he researched it at work, talked to the tech's and was
told Straight Talk ordered the phones this way to stop people from buying their cheap phones then switching companies.
Hi
My friend has got S4 (I9505). He wasn't flashing his phone with anything - it is original like it was bought. He has got now I9505XXUBMGA firmware (Android 4.2.2) with BTU CSC, which is outdated. System status says that phone is not modified, but despite this, he is unable to do OTA/Kies update. In both cases (when using OTA or when connecting to PC with Kies) he got message "This is the latest firmware". This is not true, latest for BTU CSC is I9505XXUGNG8 (Android 4.4.2).
Questions:
1) What can prevent OTA/Kies from update of unmodified phone?
2) Can software say, that phone is unmodified when it is not true? For example when flashing count is not "0"? Maybe someone flashed my friends phone before he had bought it? Changed kernel or recovery can lead to such problems?
3) Freezing of some Samsung bloatware can lead to locking both OTA and Kies on PC?
4) Are we able to diagnose this phone (how?) and fix OTA to avoid Odin flashing? (I know that there is hard to brick Samsung phone completely, but there are always some small chances that something will go wrong, my friend is not keen on flashing and I'm not so rich to buy him another one S4 when something will fail )
Thanks for answers
From what I recall, the S4 firmware will report a status of Official if all the pieces match, regardless of whether the firmware actually is for the S4 in question. So it is possible, and in fact likely, that your friend's phone was carrier branded at one point, but was then subsequently unlocked and the firmware flashed with an unbranded firmware.
You can find out if the device was flashed by entering the IMEI here. One item it will tell you is who the original carrier is. From there you can put two and two together.
Thank You very much for reply, that's important clue. I don't know how phone was bought, but CSC reports UK (BTU) and I'm not in UK - Poland. So it could be sold by some UK carrier and then unlocked to unbranded firmware.
IMEI gives no results, but I will try to get more informations about how phone was bought, that can explain a lot... Looks like in this case Odin will be only way to push Android further...
Thanks for answer, now I know for what I should look :good:
If anybody else will run into other idea - also feel free to answer, I will check anything as I want to help my friend Thanks everybody, XDA is great
Just a follow up. When you entered the IMEI at the link I gave, did it come up with the device's model number, e.g. GT-I9505ZKAXXX? If so, did yours read "GT-I9505ZKABTU" or some other model?
No, unfortunately not, I see no data after entering IMEI, only information about API, however if I enter IMEI on main page of this website I see some basic data. This lead me to information that Reporting Body Identifier is BABT (IMEI starts with 35) and BABT means United Kingdom.
Website didn't show model number, but my friend has installed Phone INFO ★Samsung★ and inside it there is model number (Product Code):
GT2I9505ZKABTU
This is very similar to Yours suggestion, but I see something weird - shouldn't be "-" after "GT" instead of "2"? Product Code with "GT2" instead of "GT-" is OK?
Thanks for answer
Then I sent you to the wrong page. You want the Samsung warranty page: https://imeidata.net/warranty/samsung
That page is the one that is supposed to tell you everything about your phone. Post that information here, minus the IMEI of course.
You had send correct link On Warranty page when I enter IMEI I got no data, only some data on mainpage of this website - looks like they don't have any information about this IMEI
I think they want you to register with the site, which is something new. Regardless, the reason we can't go by the Phone Info information your friend provided is that when a new firmware is installed the product code changes. For example, my I9505 was originally a GT-I9505ZKAO2U, which means my S4 was originally tied to the carrier O2 in the UK. Before I purchased the phone, the product code changed to GT-I9505ZKASIM, which is Slovenian firmware, specifically SI Mobil. About a month after I purchased the phone I installed a Black Edition firmware, which changed the product code to GT-I9505ZKAAUT, an unbranded Swiss firmware.
Currently on his phone is an unbranded UK firmware. If the site doesn't reveal the original carrier, the box may, depending on how long he has owned his S4. Some boxes have the product code on a label attached to the box.
Looks like website is down - after registering I got still no data, just message "The TAC info not found on database, we will update in 1-2 days."
Thanks for help - I will try to get details from my friend and I will go back to this when I will have some new infos
Hi first post here but not a complete newbie. But this time I'm stuck big time and would appreciate some help.
I've got a s8 plus that recently started playing up. All of a sudden it started not being able to make or receive calls. But I noticed it only happened when the "conditional call forwarding active" message didn't appear when dialing. I figured it had something to do with call forwarding so try to change the settings on supplementary services settings but when I tried to enter the settings an error message appeared "failed to read data" I tried sending the code manually to cancel voice mail *#022# to see if it would work but I got "connection problem or invalid mmi code" so assumed it could be that the phone is trying to check with the network the forwarding settings as the call starts but for some reason it cannot communicate with it as the mmi codes don't seem to working?? (I'm not that knowledgeable in that area) I tried all the fixes online for the "connection problem or invalid mmi" but none work so I flashed the firmware through Odin even tried a few different ones, I've been playing around with Odin for a while so I'm comfortable with it, I even flashed a pit once for a note 4 that was bricked (just saying so you can see I'm comfortable with using it, not an expert just comfortable) but nothing has fixed my problem my phone is a g955fd running pie and one UI with the latest security update. I've read the duos have some issues with this. I've tried other sim cards on my phone from different carriers and the problem is the same and I'm using my sim on a borrowed phone and no problems. I'm assuming the problem goes deeper than the firmware, could this problem be boot loader related? Would a nand erase and reinstalling the boot loader fix it? Everything else works 100%
Someone please help me, the phone I'm borrowing is an apple and every day I have it I feel weaker and dumber, it's like kryptonite.
Sorry for the long post but I've been browsing xda forums for years and I know that you guys always say to share as much info as possible. By the way I've searched and couldn't find a thread about this but it there is one I promptly apologize and just ask for the link to it if not thanks in advanced.
? G935F or G935U exynos vs snapdragon
Way for snapdragon
Flash https://forum.xda-developers.com/galaxy-s8+/development/rom-t3901074 with odin and test with hard factory reset recoery.
After, flash odin last firmware stock sammobile
Thanks
Thanks for your reply deadedge7
As I said my s8 + is a duos g955fd variant and has an Exynos processor, I'm not sure that rooting it would make much of a difference, as to my understanding rooting doesn't really change the boot loader it just allows you to install a custom recovery and roms. Which is not much different to reflashing a stock rom for all intents and purposes , but I might give it a try anyway. I guess that maybe a rom like the one in the thread you shared might give me some more hidden codes access as a root but I'm not sure. I will try to find a root like it for my variant unless you know of one and can point me to it.
Thanks
Hard reset or flash stock software or hardware problem

No solution so far. I've rooted the phone and install a couple of custom ROMs but still nothing. I'll try and roll back the firmware and see what happens. I'm no expert but I still think it is fixable. If I find a solution I'll post it on this thread. If you find one please share. My solution at the moment is getting a galaxy A50, very comparable performance with the S8 and really cheap.

I'll keep that in mind. Couple of things to note: I don't get the message conditional call forwarding active. I don't think I ever have.
I tried a different carrier SIM card(T-mobile) and it worked (I'm on At&t). I was able to make and receive calls. Even tried an out of country SIM card and received calls. But my At&t SIM works on other phones perfectly. Go figure lol.
The only other reason I can think of is maybe cos it fell a couple of times from the couch. About 1.5ft. New case kept making it slide off.
