1) the SGHI747 comes with unlocked bootloader. (bricked my first trying to "unlock" it. lol. now anyways).
2) do you know your current bootloader/modem version ?
3) you know this is the att thread , right?
"all i can really do , is stay out of my own way and let the will of heaven be done"
Its running the bootloader for 4.4.2 it was already upgraded to kk all ive done sofar is to root it and flash a custom 4.4.2 rom on it.
Yes its the att s3 its actually a friend of mines phone hes on tmobile but his mother is on att from which he got the phone from.
I had no problems doing this to my note 2 but this s3 seems to be a little bit more finicky
We talked to att customer service just a few minutes ago and they said his mom needs to be the one to fill out the form online which is an option.....but he really needs his phone up now and att csr said it will take another 3-5 days to get the code.....I jist figured I could do it easily and faster lol since i am a flashaholic and unlocked many of the other GS phones
I have found a thread about a modified downgrade firmware to odin back to 4.1.2 that will allow me to unlock from there....

well if bootloader is NE4 or NJ1 all i've ever read says that to downgrade will brick the phone. but..... if you can get to 4.1.1 there is a code to enter from the dial pad that will unlock. if someone has found a workaround to downgrade that would be awesome. save a lot of people a lot of trouble. if you dont mind please post results and the link to the thread.:good:
"all i can really do , is stay out of my own way and let the will of heaven be done"
I'm also on KK. My device is a I747M. I tried the 4.1.1 downgrade few minutes ago. The Service mode code works but one option is not available because modem cannot be downgraded.
Screenshot 1 > 4.1.1 with KK modem. modem downgrade gives :baseband unknown"
Screenshot 2 > Under Network Lock, "NW Lock NV Data INITIALLIZ" option not available

Hmm not good.....yea im on ne4 and was hoping that worked....guess my buddy is going to have to go the other route.
That was the way I was planning to go....downgrade and use the menu code
Downgrade from 4.4.2 to 4.1.1 i747
does any tried downgrading from this? 4.4.2 to 4.4.1
im using i747 kitkat 4..4.2
can i downgrade it using samsung kies3?
In order to unlock, you need to be running the 4.1.1 bootloader. Once the phone is running a 4.3 or higher bootloader, you can't downgrade the bootloader.
Thats where Sammy pisses off its main users
At&t sent him the unlock code but its not working and also has the warning that if you try 5 or more times that the device will be permanently locked to at&t.
Any ideas there?
Are you getting the prompt to enter the unlock code? Are you running a stock dialler?

I currently have OTA 4.3 installed (Rogers version from SamMobile -SGH-i747M). I would like to unlock the phone. The only methods I could find involve reverting to 4.1.1, which is impossible after OTA 4.3 update (according to many other XDA threads). So, 2 questions:
1) Are there any known 4.3 unlock methods presently?
2) Are there any known methods for reverting 4.3 to 4.1.1 presently? (to use old unlock methods)
Thanks!
Update: I've been able to downgrade from 4.3 to 4.1.1 by using Mobile Odin ( http://forum.xda-developers.com/showthread.php?t=1347899 ), which does not flash the bootloader (so the bootloader stays at 4.3, bypassing the failures when trying to downgrade with regular Odin). It required rooting 4.3, which I achieved with method 2 here: http://forum.xda-developers.com/showthread.php?t=2538991
However, now when I attempt to use the unlock method posted here: http://forum.xda-developers.com/showthread.php?t=2014982 - when I get into the Service Mode screen, there are NO options (instead of the 3 before or the 4 required to complete the unlock). I've attempted flashing modems from this thread: http://forum.xda-developers.com/showthread.php?t=1831898 to no avail.
Suggestions?

You downgraded? What 4.1.1 Rom or file did you flash with mobile Odin to downgrade?

I tried both the 4.1.1 AT&T and the 4.1.1 Rogers files from SamMobile (the phone is locked to Rogers). In both cases, in About Phone the "baseband" shows as "unknown", which I'm guessing is why the Service Mode menu shows nothing: something about being unable to detect the modem? Using regular Odin to flash the Rogers 4.3 ROM puts it back to its normal state with the baseband showing normally.
Another possibility is that the 4.3 bootloader (which cannot be downgraded) does something funny so that even if you're running 4.1.1 for everything else (bootloader still at 4.3), it screws things up? Not sure how that would work.
Tried another method - No luck
Update:
I've tried the 4.3 method suggested by Mr. X in this thread: http://forum.xda-developers.com/showthread.php?t=2529200
Unfortunately it didn't work for me (a couple other posters report that it didn't work for their 4.3 devices either).
I have seen some variants of the Service Mode unlock with different menu options (since 4.3 doesn't have the 4 required that are visible in 4.1.1). Any suggestions on other menu options that might work?
Any other ideas for unlocking 4.3 devices?
Bump - Lots of people have same issue
I've been watching the forums and this thread keeps coming up. Lots of people want to unlock from OTA 4.3. I'm bumping this thread because I've detailed what I've already tried with links so that things don't get repeated too much.
Anyone found a way to unlock from 4.3 yet?

I asked the same question a while ago and no answers came up. http://forum.xda-developers.com/showthread.php?t=2541909
I ended up paying one these services that give you the code. If you do that make sure you are on stock ROM or it won't work. Hope some solution comes up.
I think we can rule out unlocking phone ourselves.
Thanks for info. So cellunlocker works.
I looked at sammobile unlocker as well... but was uncertain if they service US customers, as they charge in uk currency.
Has someone in US tried sammobile unlock service on s3 on 4.3 successfully?

You guys try "galaxSim unlock" from the play store...says it has 4.3 support. Worth a try. I think there is actually a thread on xda that the developer lets you use the app for free.

I didn't know that these phones were region-locked. Does this mean that a Canadian s3 that has been sim unlocked may not work in Europe?

US phones aren't region locked because they're already SIM locked (I have no idea what the situation is with the Verizon Note 3). I'm not sure about Canadian phones - the region lock appears to exist on phones that are sold unlocked. (All you have to do is activate the phone in the region it was intended to be sold/used in and the region lock is removed - you only encounter issues when the first service you try to use the phone with is outside of its region.) But someone found that RegionLock Away SIM unlocked his T-Mo Note 3, and since then it's been found to remove the SIM lock on quite a few Samsung devices
Hello,
I've got a little problem. I need to downgrade my m919 from 4.3 to 4.2.2, because i need 4.2.2 to unlock this phone, z3x does not support 4.3. Arleady I have 4.3 official installed, and I've heard that there is some problems during downgrade, and I dont want to brick this phone. Is there any solutions to downgrade to 4.2.2 ? I was looking for answer but didint find it.
Thank for a help.

Unfortunately that cannot be done, once you have upgraded to 4.3 MK2 you cannot downgrade.
But there are plenty of excellent custom roms which are 4.3 MK2 that you can flash.
NOTE: if you have flashed the official Tmobile MK2 4.3 Odin flash firmware/rom OR if you
have allowed the OTA update and or if you upgrading using KIES and your phone is not yet
rooted and does not have any custom recovery or custom rom in it then you don't need to worry
about your warranty, it will stay GOOD as long as you do not ROOT the phone and as long as
you do not flash any custom recoveries, roms or kernels.
Good luck!
I don't need excelent roms, i need to downgrade, because the Z3X doesn't support 4.3, and i cannot unlock this phone. Or is there any other ways to unlock this phone @ 4.3?
btw. Even if I would flash again stock 4.2.2 via odin and i would restore via CWM image from 4.2.2 it woudnt work?

Get an unlock service. You'd have to pay for that since I believe the 4.3 kernel has the CSC codes removed. No way to downgrade from 4.3 BL. Good luck.

Definitely more info needed.
What ROM is on your device?
What bootloader did you install?
What modem/baseband/radio is on your device?
What method did you use to try to install the bootloader?
Is your phone still showing the correct IMEI in settings or 0 ? (Compare between that shown in settings and under the battery.)
It may be as simple as updating your modem, but I/we can't tell yet.

I'm new at this, in fact I have flashed by old Captivate several times but yet to flash my SGS3. Anyhow, I have spent many hours reading. Before doing anything I suggest, read, and read some more.
Don't flash back to 4.1.1 or 4.1.2 at this point. They will install an older bootloader than is currently on your phone. From what I have read, you narrowly escaped bricking your phone. You might want to read some of the threads regarding the 4.3 stock ROM and unbricking before making any changes in restoring your device.
You can probably fix this by flashing the modem that goes with the 4.3 series ROMs. It would also be the MJB flavor, although the MJ2 would probably work. Several of the 4.3 TouchWiz ROMs in the development forum have download links for the MJB modem. I would guess you were probably going to install one of them. I would recommend flashing the modem to see if that solves your issues before going ahead with the ROM flash.

The reason I didn't put a link in the previous posts was to get you to read about what you were doing as you searched for the modem. I am offering advice on things I have yet to experience on this device and only speaking second hand. My advice is only based on what I have read not on anything I have had to correct myself.
In truth I think you just stopped too soon in the process of what you were doing earlier. You said you installed the 4.3 bootloader in preparation to installing a 4.3 or later ROM that required the up to date bootloader. You didn't mention installing the current modem/baseband. You didn't mention trying to flash whatever ROM you had been considering.
You may be able to correct your device simply by installing the 4.3 modem. HERE is the modem thread, it is in the General Forum for our device. Make sure you pick the correct one. I don't know if your device will work well on the MJB bootloader and modem with a 4.1.1 ROM, from something I seem to recall reading I suspect it will.
Take this in steps. Install the correct modem, the one that matches your bootloader. See if that corrects you sim, data, and IMEI problems. If it does correct the issues, the next step is to decide if you want to stay on the 4.1.1 ROM or change to whatever ROM you had been considering. If you decide to change, make backups first. If it doesn't fix the problem while on 4.1.1 you may want to flash the version of the official 4.3 ROM enewman17 has provided on the development thread.
Take it one step at a time. Read about what you are about to do until you understand it well, all before doing anything. Make backups sequentially as you make each corrective step.

Did that modem fix some of the problems?
If your on 4.1.1 shouldn't you flash the DKL3 version or can't you just flash thru Odin the DLK3 stock ROM thru Odin Amd start all over again
I've been on 4.3 with that bootloader Amd have flashed back to 4.1 back to the baseband version DLK3 firmware. I would think being on 4.1 you should be able to reflash using Odin to fix the issue or flash the modem for 4.1 .
I need to unlock my phone.
A step by step guide will help me big time. I updated to the newest update which is 4.3 but then people were saying if i downgrade it'll brick my phone. Is there any way to downgrade?
You need to be on a completely stock 4.1.1 ROM, including the bootloader. Since you have updated to the latest 4.3 ROM, you would have the 4.3 bootloader on your phone and this bootloader cannot be downgraded.

You are stuck as there is no way for you to revert to prior roms. You heard and read correctly...if you try and revert your phone to a version prior to 4.3, it will be nothing more than an expensive paperweight (bricked). If the phone is an AT&T model, call AT&T and see if they will give you the unlock code.

Hi i'm attempting to unlock my Brother's S4 for him. I haven't unlocked anything manually in nearly 2 years back when I did my EVO. But his phone is currently 4.3 and it's M919. The couple guides that I found that seemed simple enough require I be at 4.4.2. But my problem is when I try to update his phone manually, it will update it to 4.4.4, which is clearly newer. So my problem is, How do I go about this? Is anything available for 4.3 that I didn't find yet or is there something i'm missing?
Any guidance would be appreciated.
Thanks
No unlocking with Tmobile.
Read the threads. ???

You trying to carrier unlock? I just did this last night mine also came 4.3 there are some great guides that explain how to do this. Basically you need to download the stock 4.2.2 firmware and flash it in Odin then you need to flash the UAV modem file then you can get into the service menu and unlock(this did not work for me) if this doesn't work you need to root then install regionaway apk and this will region and carrier unlock you this worked for me. Next you need to flash stock 4.3 or 4.4.4 its been over 10 days since you made this post so if you still trying to unlock your brothers phone reply here and I will find the guides and post them.
