[Q] Upgrading an Unlocked AT&T Samsung Galaxy SIII - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I sincerely apologize if this has been asked before. However, after lots of searching, I have been unable to find an answer anywhere.
I am more experienced with iDevices as opposed to Android. With Apple products, as long as the device is not factory unlocked, every time the firmware is flashed, the unlock process will need to be redone.
So, I have an AT&T Samsung Galaxy S3 which is unlocked via an unlock code, and I use it in the Caribbean. I'd like to update to the latest firmware (4.0.4 > 4.1.1) using Samsung Kies, on my desktop. Before I do so, I'd like to know will the phone remain unlocked after flashing the new firmware? Or will I need to unlock once again?
I apologize if this is a stupid question, but I'd just like to be precautious. Thanks for any help in advance.
P.S. My device is rooted. Will this affect the update?

I don't think the update will effect the unblocking....
But why update thru kies when the stock/rooted rooms are found here too??
Kies will have issues updating if your device is rooted.... So just flash the stock rooted images, via Odin program, here on XDA.
Here are the stock/rooted 4.1.1 ROMs with Odin program as well:

Alright, thanks. I'll use Odin instead. But can someone give me a definitive answer on whether the update/flashing will affect my unlock?

Thanks a lot guys. Appreciate the answers.

Sorry for the double post. However, just updating that I just successfully updated to a fresh install of 4.1.1 from 4.0.4, and my unlock is indeed still intact. So, anyone else who is a n00b like myself, and is worried of the same thing when updating, don't be.

Hello. I am new to samsung. It came from At&t and i unlocked it here in the philippines. And as ive checked the software it is still 4.0 and since i want to update the software it only says communication failed. May i ask if is it possible to update my s3 to the latest version? Im really desperate Thank yooooou.

A phone can be relocked once an unlock code has been entered but this only happens if the phone undergoes a repair and the IMEI is changed.
Also, just to calrify as the original responder has mentioned "blocking". A blocked phone is very different to one that is locked. This might confuse people but just to confirm, if you have a blocked phone, unlocking it won't help. A block is done at network level and stops the phone connecting to any network to make or receive a phone call. A lock is at phone level and simply limits the phone to working on one network only. A lock can be switched from on to off to allow it to work on all networks but a block can only be removed by the networks.

Doesn't look like mskip has added i317 model yet.
I flashed CWM 6 for i317 and installed superSU 0.97 via CWM. It seemed to do the trick.
Be wary that the phone not only counts flash attempts, but also has a flag for whether the phone has been modified. If the phone is flagged you will lose the ability to do OTA updates.

You can grab the i317 cwm recovery from here:

you can grab supersu cwm flash zip from here:

again i warn you that you can't ota update after this, but getting rid of rogers bloatware through titanium backup was much more worth it for me for the time being :d.
Perhaps you can tell me this, are there any ota updates out of the box? Or is it updated already?

Would you recommend this root process, or do you think it best to wait for mskip to post an update to add 317 support to his tools? I have rooted many an android tablet, but have never had to deal with a phone before. Why no OTA updates after achieving root? I noticed people passing their #1234# on, does this mean that we are overwriting our EFI partitions which hold some of our unique identifier number, etc. As I said, I'm not used to the phone partition structure, or the use of odin, but have spent quite a bit of time in adb and cwm.
Cheers
EDIT: Sorry, I just reread your post and noticed the quote about the 'modify flag', and then being denied OTA updates. Stupid me, I then decided to go to the source, Triangle Away, and found out it is related to the counter in a hidden boot block. Ignore basically everything I had asked, I know better than to post without searching first. Sorry.
I just got mine from Rogers today. Am with Virgin, and since Virgin is owned by Bell (or Virgin uses Bell network), I took my sim from iphone and put it in GN2 and it worked instantly.
Let me know if you need any info...
Im an anroid noob, so need to do some research before I root. I dont have ANY bloatware, so thats not an issue.

OK just so im sure....
-Reboot device to download mode
-Open odin and select downloaded file for PDA tab (cwm6-recovery-i317.tar.md5)
-Connect device to PC, and wait till device successfully added to com port
-Flash
then again
-Reboot device to download mode
-Open odin and select downloaded file for PDA tab (cwm6-root-note2.tar.md5)
-Connect device to PC, and wait till device successfully added to com port
-Flash
Then that should root and install supersu?
LMAO, I looked at 3 different root methods and now am not sure what you guys did in this thread to root your i317...and im a droid noob.

The second part no! Do the first part you mentioned. But put superuser97.zip in root of phone first! Then reboot into cwm vol up/home and power together then let go at boot screen. Then flash the superuser97.zip via cwm done

Thanks that worked perfect.
I did actually do the second part (before you replied) but just reflashed with recovery and all is well. ...I think.
Is there a good FAQ somewhere? I have looked at a couple but they seem device specific. My questions are regarding the actual root then ROMs. I would imagine that since a ROM changes the entire OS, it must change the root? Or once the stock rom is rooted, they all are? Stupid noob questions, that im sure a FAQ would answer.
Cheers, and thanks again!

Yea thats mskip great work and tool kit! hes adding our devices into his toolkit as we speak
Hi turilo,
I apologize for the noob questions - I'm new to the Andriod ecosystem and I just got a Note 2 (Rogers) and have a couple of questions.
1. You rooted your device and what exactly did that accomplish? It appears you were able to get rid of the Rogers bloatware. So all the red colored Rogers app icons and software are gone? What else is the benefit of rooting your device in particular? Is it faster and the battery lasts longer? Please be as specific as you can.
2. Did your device retain all the TouchWiz and S-pen funtionality after being rooted? In other words rooting did not make your phone a pure Andriod system? I also have a Google Nexus 7 and can see differences in the OS compared to the Note 2, so I'm assuming the differences are "enhancements" (depending on your perspective ofcourse ) that Samsung put in.
3. As someone else mentioned, now that you will not be able to get updates OTA, does this mean that when Samsung releases the update to allow multi window or any other update for their software, you won't get that automatically? Is this not something to be concerned about? I would want to get any updates to the S-pen or TouchWiz for instance.
4. Does the above also mean that when Android 4.1.2 becomes available, you will have to update your device manually using some archane process? ie, you won't be able to do this simply from the Settings menu and click on update software?
5. Last noob question - for Andriod idiots like me (I'm a little bit techy - I jailbroke my iPhone back in the day, but would rather not root my Andriod phone unless the benefits outweigh the disadvantages - get rid of Rogers bloatware, keep the Touch Wiz and S-Pen functionality, improved battery life, faster processing etc), can you point to a link that explains how to do this for Andriod dummies?
Thanks!

Updating Bootloaders? Please read this first

Since the new Jelly Bean bootloaders have shown up, I see a lot of people talking about updating them. There are a few things I would recommend to do when flashing them. The first is the small, but present, danger that you can hard brick your phone. And I mean the "Need jtag to make it work" hard brick. Typically the cause of these bricks is an error or interruption of communications between the device and the computer. The other is mismatched or outright improper bootloaders.
Below is a list of things to decrease the possibility of permaborking. Keep in mind that following this list will not 100% remove the danger of flashing bootloaders, but will increase the chances of a successful flash.
Flashing bootloaders is dangerous. They are one of the few things that has the possibility of hard bricking your phone. For that reason, here are some good things to do to prepare for flashing them.
Have a good, reliable data cable. Interruption of communication between your phone and pc will most likely cause a hard brick with bootloaders.
Use a usb port on the back of your computer (or #1 on a laptop). Communication, again.
Have a jig. Not much help if you hard brick, but if you soft brick its very nice to have.
I personally flash bootloaders from a good laptop with a fully charged battery. If there is a power outage, the battery in the laptop will have saved my phone.
When flashing bootloaders,or anything with Odin, don't touch your phone after you connect it in dl mode until the phone reboots. Goes back to the communication issue.
For problems/tips on connection issues, look HERE
To determine which bootloader you have, check out this app:

Hi,
I know this is close to impossible, but still want to bring it up to see if anyone here knows.
My s3's USB port seems damaged physically or something. It charges fine, but it always shows unrecognized USB device when connecting to PC. No matter it is in download mode or booted mode and how hard I try(install updated USB driver, change PC etc. )
No the question comes - can I upgrade boot loader without USB? If not I will be stuck with older version of cm10.1 for ever
TIA

No, you need a usb port to do it. You might try using Heimdall, as it uses a different driver. If you use heimdall, you will need to do a lot of research as it operates a little differently than Odin.
Flashing Bell Galaxy S3 Bootloader on AT&T phone
Would it be possible to flash a SGH-I747M (Bell) bootloader on a SGH-I747 (AT&T). I would like to have the option to toggle LTE off when I am in a non LTE area without going through the Network Control option discussed on xda, as I have been doing.
If it's not the exact bootloader for your phone, don't flash it.

It is not recommended to write bootloader with Mobile Odin. Furthermore, it just won't do it:
From Chainfire:
All partitions are supported, as are loose files, .tar files and .tar.md5 files. Mobile ODIN will even check the MD5 signatures before flashing. While in theory Mobile ODIN can repartition and flash EFS and bootloaders, it will cowardly refuse to do so, for your own safety.

I have no idea why you would have to do that. If you have your setting correct it will do it automatically. My does on Telus. Or did you follow some of the instuctions here and loaded a bad image to your phone. Best to flash a stock image to your phone that has been rooted and then use rom manger or goomanager to flash a recovery to your phone if you want one. I have a rooted stock rom and I no recovery as they are a waste of time. I used triangle to reset the trip and I can update OTA with no issues and it states my devise status is normal. I had used some other rom on my phone and it drained the battery all the time. Now it works like a charm. I can even use back track or other linux distro's on it,
As for the other guy having an issue, you can update your phone over Kies. Your issues sound like its a bad rom you put on your phone. And you can never brick your phone. Its what people to say to scare you to get you to use their methods.
Is it possible that installing a custom rom would have installed the latest bootloader. I didn't install myself and it looks like I have the latest per the device info app I downloaded from the play store

The AT&T SGH-I747 does not offer the option to toggle LTE off under the Settings Menu, as do the Bell, Telus etc SGH - I747Ms. And although I can and have flashed all sorts of different ROMs, the AT&T modem is RAT locked and I so far have been unsuccessful flashing any modems other than AT&T modems. I am not sure whether this is a software issue or whether it is to do with the AT&T bootloader, hence the question about flashing a Bell bootloader. Any time that I try to flash a non-AT&t MODEM, I temporarily lose my IMEI number and the phone will not work at all. But there is a work around by entering into the Phone Control settings as discussed on xda, ( http://forum.xda-developers.com/showthread.php?t=2116346) which I have been using successfully.

If your phone came with 4.3 already installed from T-Mobile or you took the official ota then you are out of luck as far as downgrading is concerned. Are yu any of tthose? if so, you will have to buy an unlock code from an online unlocker like FastGSM

i have Note 2 ATT, i am having network connection problem. i can't connect to my ATT network connection . i get circle with line in middle.
i took my phone to ATT store and they tried changing the Sim card and even updating my phone to the latest update, but it did not work.
i tried downgrading my phone to stock Rom when i downgrade the phone. it seems to work fine for five minutes or so i even made a call after one call it started showing same circle with line in middle. i tried flashing all different Rom, i even tried re flashing MJ4 modem. nothing seems to work.
i research to find a solution but i didn't find any solution to this problem. right now i am on Sky Note Air 4.3.
please help me i appreciate for any help.
EDIT: i flash back to stock Rom 4.3 with rooted MK6 bootloader. just to see if it makes any different on my networking problem. And still have issue with not networking data.

Try flashing 4.3 rom from scratch (wiping dalvik cache, data/factory reset and cache partition) ? May be this will help fixing problem
If you want you can try Stock Rom - http://forum.xda-developers.com/showthread.php?t=2589891
Also make sure you have an APN set. @Bajanman has compiled a list of several AT&T APNs in his thread here: http://forum.xda-developers.com/showthread.php?t=2172110
I had a similar issue and this post helped me.

Also check your SELinux setting.
Once I set mine to permissive all was well.

They are not hacking my friend...
Have you verified that your IMEI and EFS folder are normal ?
And have you verified your APN settings for your carrier ??
You mention flashing several roms on the device...
The items I listed will help you determine if any damage has been done....and also help you get service again...
All are knowledge you must have to prevent bad things from happening...
If your carrier did an official update to 4.3 while the device was rooted and running custom firmware....then you absolutely need to start fresh to clean the device up again...
Are you getting Knox errors or force close issues ??
Basically....in order to help you we need a detailed status of the device...
Software version....kernel version ....and baseband.....
The information is in settings/about phone/....and will tell us how best to proceed....g

I'm confused. The first post you were on Skynote 4.3.
Now you are 4.3 stock rooted ???

I'm still confused.....
Reading your first post, ATT flashed your phone to the latest update??? And changed the SIM? And that didn't work?
Why did you leave the store when your phone didn't work?
They told me they can't do nothing about it and the warranty was voided too.

Interesting. I'm asking questions I guess really dont matter.
But why was warranty voided, or was it expired?
Again more confusion.... Just wondering why they changed sim, flashed update, then told you to hit the street with a broke **** phone.
I can understand not replacing it, warranty whatever.
I took an Atrix2 phone into the shop, no working data. I had called tech support, they had OTA refreshed it, didnt work. Set me up with tier 2 tech support, more resets. Nothing.
Went into store, got another sim. Turns out it was simple. I had turned off the data plan awhile back until I was ready to give it to my daughter.
Got online, picked a plan. Data lite off.
Point is they worked with me to find the problem on a phone that was 2-3 years old.
You probably should follow me how to in this section and flash the stock 4.1.1 and go from there.

Well you have nothing to lose at this point then.
I doubt you will find a canned click next solution.
You will probably have to go the "hacking" route.
Good Luck.

Unlocking A505U Bootloader with ADB

I have an A50(A505U through Sprint) with a locked bootloader. I've tried the 7 day trick to enable Oem Unlock in Developer Options but it doesn't work. I'm wondering what the chances of being able to to force oem unlock using adb is without bricking my device? I figure this is to easy of a solution but hoping someone is willing to try it!
I also have the same Sprint A505U and I'm having the same problem. Hope we get a resolution for this.
im picking up a verizon A505U tomorrow.. out of curiosity, are you able to flash combo firmware?
also to add, you cant force oem unlock using adb.. you can probably set the oem unlock to on in adb but it doesnt actually change the unlock bit wherever its stored in the firmware so as soon as you reboot its back to 0.
If you can flash combo however you can enable oem unlock then flashing back to stock the oem unlock bit should remain on.
Either way, I will be playing with it all weekend lol.. i just hope its not like the A102U i purchased from tmo which doesmt let me flash anything

Yes I have used Odin to flash a sprint firmware from samfrew and and found out it was sprint verzion firmware when poking around.
I suspect it is going to be the same. All U variants can't be unlocked from what I've been told.

To flash vzw/sprint combo firmware? I flashed it on a 505u from Sprint with Odion after an expirament resulted in a soft brick.

Nope. I got in to download mode and flashed the sprint firmware from samfrew and it works fine. I discovered the firmware has some vzw apps included but not all of typical vzw bloat.

im confused lol..
i can install stock firmware fine whether its sprint or not..
what im wanting to flash that i cant so far is the A505U Factory Combination firmware, not the stock based firmware.
Factory combo firmware usually cant flash and will say it needs approval to flash factory binary..

I take it it's currently impossible to unlock the bootloader on the SM-A505U?
I haven't done much with Android since I had a spat of amnesia so I don't remember much, but is it possible to root this phone without unlocking the bootloader? I don't have any plans of installing a custom ROM, just want root privileges.
Witam! I znalazł ktoś jakiś sposób na odblokowanie? Zależy mi bardzo na TWRP oraz Root.
Was anyone able to flash a combination AP file? I get a secure check fail for everything. I'm using Heimdall. Whichever packet is uploaded first, it will fail at that packet.
Edit: Just realized it's probably because of RMM state. Has anyone discovered a bypass? I guess I'll try waiting for 7 days with no sim card and see if that does it. Tried Chimera tool to RMM Unlock with no luck

Following along this thread. This is my first post ever. I have some experience with odin and Samsung. I would like to try out flashing and return with the results. Not afraid to soft brick. Could I possibly get a link to anything you have so far and I will share anything I find? Thank you.

So basically there's no frp bypass working? Besides hardware like z3x?
