Hi there! So I have an interesting problem. I have a Galaxy S3 I got from AT&T and I've had it for a while. Now I want to switch to T-Mobile. I already have a sim card for them. However, the phone is locked and has been updated to 4.3 (unfortunately). I've looked around and there doesn't seem to be anyway to unlock your phone for this version.

I also don't know if and when I can get a code from AT&T since the account is not in good standing (I am not the payer of the account and he is being useless). So I'm seeing what options I have and I was wondering if I used a custom ROM for AT&T (such as Intergalactic), if it would unlock my phone as well so I could use it with T-Mobile. I'm relatively technology savvy but not at all with phones.

If this method isn't possible then is there any other way at all to get my phone to work with a T-Mobile sim?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] pc103:
There is a well documented free unlock procedure (in the General thread here for example) using a hidden engineering menu. Things to remember:

1. Your 4.3 Bootloader must not be touched by any flashing of older bootloaders on pain of BRICK!!!

2. Routine modding like custom recovery & root can break your 4.3 mfr. warranty irreversibly.

3. The method I referred to is done on a combination of earlier stock modem & rom. Stock modem, kernel & rom flashing back & forth from your 4.3 FW poses no risk beyond the usual (as long as you follow rule 1.)

4. If you choose this method, do not "dirty flash" over existing data & caches. It is far safer to obtain thorough backups & be prepared to reset & wipe between all flashes.

All I can say about performing the method is look for a neat, readable list of the steps. Understand each step fully & pause to breathe deeply before reviewing & executing each one.

So I have deduced by trying every kitkat out there right now that USB mass storage is not part of the basic build yet. I don't know if CM just hasn't tackled this issue yet or if the GS3 isn't compatible with the USB mass storage function on kitkat. I'd really like to be able to plug in an adapter that reads SD cards because I have a dslr camera and I like looking at and sharing pictures on the go. TW roms work fine with this. So, is there an easy way (hack/zip/other) to enable this functionality? Thanks.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] joshua14:
Straight to the point. If someone is thinking about flashing ROM's and has any reason to hesitate then you should be happy with root or do research upon research before trying anything.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
Some newer ROMs require updated bootloaders. If possible, avoid going to a 4.3 bootloader as it can be a pain to unbrick the phone if you run into a problem.

Why not flash Philz Touch? It's based on the latest CWM and can be flashed in Odin.

Installing a custom ROM will not sim unlock the phone. The only method available right now is to buy an unlock code.

AT&T never publicly released stock 4.3 ROM that can be flashed via Odin.

sd card unexpectedly unmounted, now not detected

Hello, a couple of weeks ago I bought a 64gb Kingston micro sd card.

It worked good, until yesterday that i got a notification that the sd card unexpectedly unmounted.

I tried pulling it out and re-inserting but it did not work. I tried in two other android phones and they did not recognize it.

Furthermore, I tried on two different windows pc's but they also did not recognize the sd card.

What can I do??
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] theramsey3:
Buy a new card and contact the manufacturer of the broken one. They might send you a new one?

No launcher, no root.

I have an AT&T Samsung Galaxy S III, SGH-I747. I rooted my phone, installed Titanium Backup and Nova launcher, and deleted Touchwiz from my phone. I started having issues with my battery, so I unrooted the phone from SuperUser, and took it to an AT&T store where they did a factory reset on it.

Since Touchwiz was uninstalled, the phone has no launcher. When it starts up, it goes through the normal loading screens, but then just comes to a black screen with a status bar. I can expand the status bar, and even get into battery stats about the phone whenever it gets to low battery and "battery usage" pops up.

I can get into recovery and into download mode, and my computer even recognizes it when it's plugged in. However, I can't figure out a way to get a launcher installed on the phone again.

Any and all help is appreciated, thanks in advance.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] pc103:
If I understood correctly, the PC recognizes your phone. You can:

Google search "touchwiz apk" to download a compatible version.

Enable side loading (settings/security/unknown sources)

Use "My Files" to locate & launch the Touchwiz home apk you downloaded. Done.

Stupid action here... I deleted my stock copy of ucdlk3... I'm not asking for it lol... but I do need to know how, other than buying a stock I747 and extracting the firmware, how to fix a glitch on my son's s3 with screen auto rotation issues. I went to dl but it's gone :( I hate AT&T sooooo much. Any hoo... will a stock kernel do the trick? I'll find a rom with d2att stock kernel. Already tried everything short of that. Sensors are all responsive and no conflicts in settings. It just stopped working period overnight last night. Lol if I buy the new phone, I could just give him that one I guess huh? I'd still like to fix it though . Thanks!

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bdithug:
May seem like a stupid question, but it's due to the confusion around the 4.3 bootloader. I have a Canadian device on bootloader MVLDLK4 running tasks latest release (4.3.1 android). I plan on testing a 4.3 touchwiz rom this weekend (most likely dandroid). I've read that people have issues after upgrading to the newest bootloader running these custom Tw 4.3 roms. If I upgrade my bootloader to try say dandroid and I don't like it, can I just restore my nandroid and everything will work as it currently is? Or will the upgraded bootloader make any difference?

I have a question regarding modems...my phone doesn't seem to know what it is anymore. When I end a quote or reply on the thread it ends with ...sent from " unknown using xda developers app" Someone on another thread said I should flash a new or update my modem. I have a SCH - I747 UCDLK Gummy ROM with KT 747 kernel My carrier is no longer AT&T but now NET10. Can anyone confirm this or maybe send a link? Thank You

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Lt1streconbn:
Don't flash too quickly....

It sounds like you may have an issue with post_efs shells. In /system/etc scroll down past the folders and you'll see a a script with post_efs in the name. It runs zygote phase of boot process... very interesting phase for the record. .. init is done but vold is rewritable in the phase... check the script there and open with viewer. It list quite other shells that set up the modem. Just check them really fast for corruption. It's easy to spot in sh scripts. it can also be a sign of incompatible firmware vs hardware. A lot of people with tabs from Sammy... sgh-i497 in particular lost their wifi because of flashing a totally compatible firmware from Jamaica. .. UMAMA2 LOL... love the that one. Flashing the right modem image actually made it worse sometimes because the modem flash didn't get along with firmware is my guess. .. flashing is the big way to quickly hard brick... you can't take it back. I don't know the rom and kernel you're using... if it's a port that could be the issue also. Try flashing faux123 d2att 24u or 24m kernel first. That's totally safe with our phones. .. it may fix it by itself and it's right here on xda :) easy to loose a modem. I use NET10 also lol.

Go to settings and check baseband and make sure it's recognized.... you might have an issue if that's unknown and need a new rom and kernel...or go back to stock firmware and cf auto root and try again. Usually fixes things.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] simpson173:
Thanks...as noted above Gummy ROM with K T 747 kernel....maybe just flash Beanstalk

Once you upgrade to the 4.3 bootloader, you cannot downgrade it. Restoring a backup will not restore your old bootloader.

Personally, I avoid any ROMs that require a 4.3 bootloader because I still have warranty on my phone.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bdithug:
That's what I figured in terms of the nandroid not restoring the bootloader. But will the backup still work even though I would have a new bootloader? And for me, my phone is out of warranty, so I'm not concerned about Tripping any flash counters etc. I just want to make sure that I have a solid backup plan in case I'm not a fan of the Tw roms that require the 4.3 bootloader.

I've used tasks rom for a long time and love it, but I'm tempted to try a tw rom since I've been playing around with xposed, in addition to the better camera quality that comes with tw.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
You're using an s3 from Bell, Telus, or Rogers? I know there are pre-rooted stock 4.3 ROMs for these phones.

I'm not sure if installing an updated bootloader will load Knox. Knox can interfere with trying to get root on stock ROMs.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bdithug:
Yea I'm using an s3 from telus, unlocked on fido network. I definitely want to avoid Knox at all costs so that's why I wanted to try dandroid.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
Does installing a 4.3 bootloader install knox? I'm not sure if it does or doesn't.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bdithug:
I think Knox is part of the rom, not the bootloader.

Does anyone know if you can make a backup of your current rom and settings with a 4.2 bootloader, then upgrade to 4.3 bootloader and then restore your backup? Will that present any issues?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Lt1streconbn:
That's why I'm sticking with 4.1.2 on my devices. They're pulling some older firmwares though from ATT. Knox 8s equivalent of S-on in the HTC phones. That's why I don't 9wn any. Eventually though we'll have to upgrade. It'll get where nothing works. Hope Mobile Odin can kick Knox by then.

---------- Post added at 03:12 AM ---------- Previous post was at 03:10 AM ----------

Read a Page or 2 back. You can't downgrade the bootloader and will have a harder time getting root. .. or maybe loose it.

Question. .. why do carriers hate us rooting our devices so much? They cram them with garbage and bloatware and hide functionality to the point their barely usable. We still carry service and developers apps to help everyone make more money and have fun also. It's our choice... we bought the things. Samsung is great because they make their phones simple to root and besides the way they defined extSdCard, they're awesome, but it's simple to mount it to sdcard0 without any app. Just a script... can use ext4 or mount thru fuse on 4.4. It's nice.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bdithug:
But since the backup doesn't backup or restore the bootloader, I should in theory be able to restore my backup still without effecting the bootloader correct? My only question is if my phone will boot afterwards using the 4.3 bootloader on a rom that was flashed using a 4.2 bootloader.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Lt1streconbn:
I have no experience with that version aside from device emulator. I'm actually reading about it now because I'm curious about whether Knox is present in bootloader and the efs check in 4.4. Bit more extensive. I still use a JB rom and it's great. I like Touchwiz :) got used to it. Someone with real experience will answer though. I'm going to read that also lol.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] simpson173:
O.K.......so I don't t know alot about how these downloads work. But I do know this rom should be between 100 - 200 MB.The download from Carbons website for the 2/13 build keeps coming in at 30.59 kb. I have seen this before but I think it's time to understand why this happens. Would someone mind a brief explanation please..... for the new guy. And if anyone has a good link hanging around of a good build that would be nice to. If it's not too much to ask. Thank you

stock i747UCDLK3 stuck on 4.1.1

Hey all, I'm confused. Our family has 3 S3's, 2 with UCALG1 baseband and 1 i747UCDLK3). The i747UCDLK3 will not update to 4.3. I read somewhere somebody stating that after some update, the new version would be i747UCDLK3, but I've never done anything to this phone. It was purchased brand new straight from AT&T.

It will not update to 4.3, keeps stating, in phone, no update available. And KIES states, current version 4.1.1 is latest version.

How in the world do I get 4.3 on this phone without rooting/unlocking? I don't care about settings as I'm more than willing to start completely over from scratch, just frustrated that the other two phones have had the 4.3 update for weeks now yet this phone cannot get the update.

One of the other S3's is rooted and unlocked, the other completely stock, both running 4.3.

Thanks for any help in pointing me in the right direction.

is a modem thread. If the ATT sgh-i747 is rooted you can flash the mg2 bootloader in recovery. the modem you want is mjb. modems are different than bootloaders and do not contain knox.

I have bee told numerous times by many people not to flash the MJB bootloader.

I think you responded to the wrong post?

I'm looking for assistance in updating to Android 4.3 on my completely stock i747UCDLK3 (at least I think it is completely stock as I've not rooted or unlocked it, in fact I've never done anything to it).
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bdithug:
If you are on complete stock unrooted, wouldn't you be able to do an OTA update on your phone?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bubsnews:
Yes, you would think wouldn't you? But, no and that is the problem I'm having. Phone states, "No update available" and Kies states, "Current version is latest version".

Both the UCALG1 versions have updated to 4.3 but the UCDLK3 version will not update and I searched and searched and can't even find others complaining about not being able to update their UCDLK3 version of their i747 S3's.

Don't know what to do...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bdithug:
Is the phone brand new or covered under warranty? If so I would bring it to your carrier and have them update it. If you have messed around with root on it, you have to figure out what you did before doing anything else. I would check your root status again, check your recovery version, see if your flash counter is tripped, see if your device is reading a modified status, etc
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] aircooledbusses:
Think I responded correctly, if not I apologize.

Same exact phone, bootloader and that is how I updated to 4.3.

The folks at att would be happy to take control of your phone, wipe it, and give you the most current Knox bootloader.

I understood you question to be how can I.....

I don't think that you can do what you want without either root or the knox bootloader being an effect.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] bubsnews:
Certainly no apologies required. I appreciated the effort in responding, my phone is completely stock. I could figure out how to root it and install whatever I wanted, was just curious as to why the i747UCDLK3 Baseband version was not being updated to 4.3 automatically as the other S3 phones have. More curious as to why I can't find anybody talking/*****ing about it. Something is going on here, just not sure what. I remember that of the 3 S3's I bought, this one was not sealed like the others.

Anyways, I followed the previous posters advice, and called AT&T, they claim they can push the update to my phone (my daughter has the phone at school right now, they are supposed to call me back later). I guess wait and see what will happen.

I really thought I could so a simple search, i747UCALG1 vs. i747UCDLK3, and I would be able to read what all the smart phone geeks had discovered about this. I was very surprised to find nothing about it, just seems strange to me considering the wealth of knowledge about the S3.
