Both my S3 (SGH-i747M) are still on original 4.1.1 and since they have been working wonderful for me (if it ain't broke, don't fxt it, right?)...plus I don't do much with my phones.
After reading about the Heartbleed Vulnerability in 4.1.1, I'm thinking of updating to 4.1.2 instead of of the latest 4.4.2, but before I do that, can I get confirmation that:
1) from 4.1.2, I can go back to stock 4.1.1 100% for sure using Odin
2) Once updated to 4.3 or 4.4.2, there is NO way to go back to 4.1.1 due to both 4.3 and 4.4.2 have different bootloaders ?
3) if updated to 4.4.2 and since there is no way to downgrade to 4.1.1, the other option would be to use "CyanogenMod" as the last option, correct?
Thanks.
1) Yes, you can go back to stock 4.1.1 from stock 4.1.2 using Odin. I recommend doing this so you can take advantage of the free unlock method.
2) Yes, once updated to stock 4.3 or 4.4 bootloader, you cannot go backwards. Also, you can brick your phone if you attempt to load a 4.4 modem on a 4.3 bootloader.
3) CM ROMs must support your installed bootloader and modem.

Thanks audit13, you are great!:good:
For the 3) CM ROMs must support your installed bootloader and modem, I have all four Koodo 4.1.1/4.1.2/4.3/4.4.2 (pix attached), are these all OK for CM ROM?
Thanks.
Last time I checked, 4.1.2 bootloader worked fine with CM 10 and I think with CM11. Keep in mind that Cm10 had some issues with some apps and the front facing camera (never had an issue with Skype) as well as Bluetooth being flakey. Read up on it and try it out. You can always revert back to stock if it doesn't work out.
If you are concerned about Heartbleed you should check if 4.1.2 is vulnerable too. Its a pretty old build and i think we were already on 4.3 by the time it became a known vulnerability. I could be mistaken though, but you should check into it if that's a concern.

Some of the newer d2lte builds may need the latest bootloader to work. You can determine which bootloaders are supported by downloading the ROM, unzipping the ROM, and open the updater script in Notepad. The first few lines of the script will list the bootloaders that are supported.

1. Put this in the Q&A thread.
2. This update came out months ago.
It's is just show up on my phone
Got the notification too but phone is unsuccessful on trying to upgrade from 4.1.1.
FWIW, I have the TWRP 2.5.0.0 bootloader and an unlocked/rooted stock ROM and the phone downloads 200+ MB of data and then reboots into TWRP. I then ask it to reboot into the system when it says the upgrade failed and boots me into 4.1.1 again.
I also just got the notification today.
I had previously had the 4.1.1 rooted stock ROM (the one that didn't trip the Flash counter) and was wondering if there was one for this update too.

if you need to update either go with customs roms with the same version but debloated, fixed and works really great or download the samsung stock firmware with Odin and you will go back to real stock with everything bloated and No ROOT
Hello. I have a rooted GS3 which I want to update. I was on CM11 but was getting bad battery life so I went back to stock via a Nandroid restore. I then installed the stock recovery again. Now when I try to do the OTA update, I get the following message

Is there any way to make this work? I am on 4.1.2 (MB1?) and would love to get to the latest stock version. Thanks

you could have left custom recovery on it, and flashed THIS from CNexus. Its stock 4.3, no KNOX, and you get to keep root access.

Thanks for the reply. Is that stock touchwiz or stock jellybean? Also what's the latest version which sprint has pushed out for the gs3?
Stock jellybean with touchwiz launcher. Touchwiz is the stock launcher. This one is the latest update, in zip format, but with KNOX removed.

One thing which stock Touchwiz has that I can update my prl etc from the rom, whereas I wasn't able to do that in Cyanogenmod. Do you know if this stock rom allows it? Thanks

Previously had the intergalactic rom and 0 problems.
But now I can not flash any cr / modem.
Any idea why?
If you have an i747m, don't flash the mjb bootloader as you do not have the att s3. You could brick your phone.

But when I flash a CR my wi-fi and data is not working. (tested in 3 roms)
And afther the first boot my phone dies an never boots again.
I need to iuse ODIN to fix it.
Flashing the wrong bootloader can brick your phone and Odin will not fix a hard bricked phone. If the ROM won't boot, it may not be due to the bootloader. I have a 4.1.2 bootloader and every custom ROM I have tried will work.

Looks like you have an hybrid firmware with the (stock) MUMUEMK3 Android 4.2 ROM and a MUMLI1 baseband/modem. The MUMUEMK3 is an official build of the 4.3. I'm not sure about the Mexican variant but I know that, with the US variant like AT&T, the stock 4.3 will not work with older modems and attempting to install an older modem always causes a baseband failure and consequent loss of all cellular functioning. I wouldn't be surprised if this is what you are experiencing and I would suggest you try to flash a 4.3 modem (MUMUEMK) instead. Or you may just look for a complete 4.3 stock image for your variant of the SGS3 and install this via custom recovery. I'd be surprised if this doesn't work.
Mmm actually I'm in the stock firmware.
But I can't find that modem (MUMUEMK)
http://forum.xda-developers.com/showthread.php?t=1831898
The problem here is If i flash a custom rom my phone only boot one time and then dies.
Even If I try to restore my backup (stock firmware) my phone never boot
Yeah I know is hard to belive (Tomorrow I record a video) but this is so confusing

Looks like most of the emphasis is on the Canadian and US builds. Perhaps we sometimes overlook the Mexican and PR variants of the I747M. I believe, however, you may be able to find the stock image at Sammobile.com. I just checked there now and found this ...
http://www.sammobile.com/firmwares/3/?download=22509
I'll suggest you try to flash the complete stock image. With the 4.3 builds, Samsung appeared to have locked the modem tightly to the bootloader.
Hi, I would like to ask you about something so confused about it ?
I have done my homework searching ? about a simple answer.

That depends. Are you on any bootloader that supports downgrade. If yes, then you can.
How should i know?
Apparently, if you ever updated your note II with stock rom 4.3 and up, then you'd end up with a locked bootloader. on the other side, from the looks of it, you are currently running a custom carbon kitkat rom, i dont see what prevents you from flashing miui 4.1.2. have you had any failed attempts or does miui requires you to be on android 4.1.2 before you install it. Unless I'm missing something, please elaborate why you think that you need to downgrade to 4.1.2 ?

when i download the miui V5 official rom and goes for flashing guide it tells me to download zip file called N7100_tools.zip and after downloading it and extract the file it contains this file N7100ZSALJ7_N7100OZSALJ7_N7100XXALJ2_TGY.TAR and seems to be 4.1.1 official firmware
that's why i want to downgrade to 4.1.2

Hi all, I just dug up my old S3 and need to go back to stock. It has a CM11 nightly on there with the MK3 baseband and CWM recovery (and no Knox loaded!). Needless to say, I've been out of the loop for the past year or so and all of these threads about Odin and the newer updates have my head spinning! I want to go back to stock but also want the ability to re-root and load a different ROM later on. If I use the Odin one click here (http://forum.xda-developers.com/showthread.php?t=2755793), would this cause any problem with re-rooting, recovery, or whatever else? I was burned on my newer Droid MAXX when I updated to a firmware that couldn't be rooted so I don't want that to happen in this case if possible.
TL;DR
If I'm on Cyanogenmod with MK3 (no Knox bootloader), what's the safest way to go back to stock with the ability to re-root later?
Thanks!

But if I was to use the one-click, wouldn't that load Knox and that would be permanently disabling any downgrading in the future? If I just flashed the stock 4.3 ROM and installed as normal through CWM, that should keep everything the same (bootloader,modem,etc) correct?
Yes... 4.3 has Knox by the way.
I flashed the 4.3 ROM and haven't had any issues so far. Still managed to avoid installing Knox somehow. Download mode doesn't mention anything about a warranty bit.
