[Q] S3 1747M Options - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I have an S3 1747M unlocked and rooted running 4.3. I am having problems since I did an OTA upgrade to 4.3 and I cannot receive text or calls. I would like to downgrade to 4.1 or upgrade to 4.4. Can I do this? Can anyone suggest what process I need to go through or what would be the best ROMs ffor 4.4?

You probably won't be able to go back to 4.1 since you upgraded to 4.3 OTA and this would update your bootloader.
I think it would be best would to install a custom recovery and custom rom.

[Q] I747M still on Rogers 4.1

Hi,
I just noticed that my wife's Galaxy S III still has original 4.1 stock ROM. I tried to do a OTA update (Rogers) but the system is saying that there is no update available. The phone is rooted.
Do I need to unroot the phone to get the update?
Thx,

Just download 4.3 Rogers and you now have the latest firmware with root. Good Luck

If you load 4.3 with an updated bootloader, you won't be able to downgrade the OS.

Yeah that is true but if you don't want 4.3 then you can always download the 4.1.2 or 4.1 instead.
Thanks ALL
Thanks All!

Coming back from 4.4

Is it possible to come back from a 4.4 rom to say 4.2 or 4.3 stock ROM? Can I ODIN back?
Currently not able to get MMS/Group messaging to work on the current 4.4 rom. Tried updating modem, adjusting settings...still no luck and I need it for work. Appreciate any help
Which phone do you have?

AT&T S3
You can go 4.4 -> 4.3. However, you cant get the unrooted stock rom of 4.3, since Samsung/AT&T didn't ever release to the public (It was all OTA).
If you went 4.2->4.3 OTA, then your bootloader was upgraded. As you've seen on these forums, downgrading from 4.3 to 4.2/4.1 is a big no-no unless you want a brick.
Example:
4.2 ---(OTA UPGRADE)--> 4.3.
Rooted+cyanogen 4.3
cyanogen 4.3-> cyanogen 4.4
cyanogen 4.4-> cyanogen 4.3
cyanogen 4.3
( ^ what I have done)
NOTE: After I got the OTA, I have never tried going back to stock. You can use rooted roms that are CLOSE to stock. But I wouldn't suggest going stock because of knox and blah blah blah.
Were you ever on stock AT&T 4.3? If you were, your bootlaoder was probably updated so you can't install an older bootloader. You can load a older AT&T ROM using mobile Odin which does not flash a bootloader or modem.
I never went to 4.3...straight from 4.2 to 4.4

So I could go back to a 4.2 TW rom if I was never on 4.3 OTA? (or any 4.3 for that matter)

Yes, you just need to find a stock AT&T ROM that is flashable in Odin.

galaxy s3 at&t variant 747 rooted 4.1.1. I747UCDLK3 update to kitkat.

Hey guys I am trying to update my galaxy s3 to kitkat. I am running galaxy s3 at&t variant 747 rooted 4.1.1. I747UCDLK3 update to kitkat. I realized I need to update to 4.1.2 first before doing the 4.3 update. I can't seems to find files I need for 4.1.2. Can someone point me in the right direction. Thank you for your help.
Are your running stock 4.1.1? If you are and your phone is not sim unlocked, unlock it using the free method. Once unlocked, use Odin to flash back to stock unrooted 4.1.1 and then run OTA until you get to KK. It's a longer process than trying to flash straight to 4.4 but is a safer method for people that are new to flashing ROMs.
I am on the stock rom 4.1.1. Does CWM recovery need to go back to stock as well? That is a good idea to unlock before I update.
If you flash back to stock 4.1.1 with Odin, it will wipe everything and put the phone back to completely unroot stock and stock recovery. Stock recovery and being unrooted is required for OTA updates.
Ok is this the link to unlock phone?
http://forum.xda-developers.com/showthread.php?t=2529200
Yes, that's it.
I can't seem to find 4.1.1 rom file links seem to be bad on unlock page.
There are stock rooted 4.1.1 images here: http://forum.xda-developers.com/showthread.php?t=1739426
You can use the free unlock method even if the ROM is rooted.
For some reason the at&t mirrors don't seem to be working either.
Mirror2 for the stock rooted 4.1.1 works for me.
I would like to root again after kit kat Is it easy to root with knox? Does unlock stick through kit kat? I really appreciate all of the help. Great website. Great people.
Many people have had success with rooting by using Towelroot.
The sim unlock is permanent.
Let me know how it goes for you @thepar. I expect to be updating to kitkat in the coming week.
For the benefit of those searching the forums to unlock their phones my experience may be of help to those on 4.1.2 or possibly even MJ2. I have had my SGS3 since June 2013 and only allowed one update, that was to 4.1.2. My phone was rooted long ago, but I just unlocked it earlier today and that was with a custom recovery in place and without unrooting. In my case I did not revert to the 4.1.1 rom. I did downgrade the modem to dlk3, that of 4.1.1 while leaving the rom and bootloader at MG2. After completing the unlock I upgraded the modem back to MG2. I have confirmed that SMS, MMS, phone, and wifi functionality is intact.
In truth, I will probably not go back to stock to get to kitkat. I am considering upgrading to the leaked MJ2/4.3 bootloader and MJB modem and then flash a kitkat rom which will work on them, there are several.
I just did the unlock yesterday. I need to find someone with a t-mobile sim to test if the unlock worked. Will I still be able to update the OS even though it is on rooted stock? What will it update me too?
I am kind of debating if I should install a custom rom minus KNOX.

If you want to run an OTA update, you need stock recovery and an unrooted system.
I have a stock recovery but the os is rooted. I don't mind using oden to update the os. I might be better to install a rom with knox removed. I can't seem to find 4.1.1 stock unrooted. I did find 4.0.1 ICS.
You can find a stock ATT 4.1.1 ROM on sammobile.com.
You cannot use Odin to flash a stock KK ROM because it was never released in an Odin format by ATT. ATT provided the KK update via OTA updates. Complete KK updates were provided for i747m only.
Thanks so much!! downloading now.
Let us know what happens. Cheers
I have decided to go custom rom route. It is better to update stock ota first then install custom rom or custom rom straight from 4.1.1?

What is the quickest way to upgrade everything to the latest note 2 software version?

Hi im a newbie and I wast just wondering if anyone knew where I can find the latest firmware update? I have an att note 2 that I flashed back to stock 4.1.1 and then rooted it but im having a hard time flashing all the latest custom roms like they keep failing! So my only guess is that my modem or kernel or baseband or bootloader needs to be updated or something! So my question is is there a way I can keep root and update these and if so how would I go bout doing so? Any answers would be much appreciated!
The simplest, but not fastest, would be to flash back to a completely stock 4.1.1 from and run ota updates until the phone is running 4.4.2.
