Hello guys,
Just have a quick question I am on stock sony android 4.2.2 rooted with a locked bootloader,
I was wondering now that 4.3 is out and I use flash tool to flash the new 4.3 would that cause any issues? I know I would lose my root (is there any way to save it) or can i just flash the new update with no issues.

If you flash the FTF using flashtool it will wipe the phone completely and obviously root will be gone. AFAIK the only way to root 4.3 right now is with an unlocked bootloader. You may want to try to update without wiping, it might preserve root. The update still hasn't rolled for the C6506 so I'm unable to try anything.

I've got a Galaxy S3 I747 it is currently running 4.1.1, I747UCDLK3 Baseband. I'm not exactly a noob when it comes to flashing and rooting, I know my way around CWM and Odin pretty well. But I have a few questions on this 4.3 OTA. (I am a forum noob)
-Will I still be able to root? (I heard CF works for it)
-Can I install CWM? (Is the Bootloader locked??)
-Will I be be able to I flash other roms than the 4.3 TW like CM11Snapshot? (Is the bootloader locked?)
-What the h*ll is knox and why should I be worried?
-What is with the boot loader downgrading thing? (Have to do with locked bootloader??)
I AM NOT AT ALL WORRIED ABOUT A FLASH COUNTER OR VOIDING A WARRANTY I AM NOT ON A CONTRACT . I JUST DO NO WANT TO HARD BRICK MY PHONE.
If you take the OTA 4.3 update, it will install Knox and the 4.3 bootloader.
The 4.3 bootloader cannot be downgraded and attempts to do so will probably brick the phone.
You can root the stock 4.3 ROM with auto root but Knox may interfere with the process of cause issues after the fact.
You can still install CWM. I rrefer Philz Touch which is CWM-based.over TWRP.
So can I still flash roms?

Yes, you can flash ROMs. Is your phone unlocked? Since you're on 4.1.1 stock, you can unlock it for free.
Personally, I avoided the 4.3 update because it installs knox and the 4.3 bootloader which can cause problems when using Odin to get back to stock.
I have a Canadian version of the s3 and I'm able to run KK ROMs with a stock 4.1.2 bootloader.

Unlocked as in Bootloader? Yeah I've been able to flash roms via CWM and Odin on 4.1.1 and as in Carrier unlocked? Yes I use Straight Talk on this ATT S3
If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?
See I can't use KK roms because I have the 4.1.1 BL so is there a way I can upgrade my boot loader to the 4.1.2 version??
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade my bootloader??
I suggest downloading a ROM you want to try, then unzip the ROM and look at the updater script to see which bootloaders are supported. The updater-script file is located in \META-INF\com\google\android\updater-script. You can use a text editor to open the updater-script file.
The first few lines will list the bootloaders that are supported. I run Validus which is a KK ROM using a stock 4.1.2 i747m bootloader.
Do you know about this > "If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?"
Also couldn't I just upgrade my Bootloader and Modem from here?

I feel like if I upgrade my boot loader then I won't have to worry about restrictions.
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade just my bootloader??
I ended up flashing the MG2 Modem and Bootloader, I'm good now, also if I want 4.3 I saw loserskater has a leak version that will be good and wont not let me downgrade my bootloader.
Hello all, I'm new to this forum and I could really use some help with my phone. I have a rooted AT&T Samsung galaxy S3 running on 4.1.1 stock with cwm. I would like to update to the latest stock OS which is 4.3 but I'm not sure how to do it right. I would prefer to keep all my data but I don't mind losing root. how should I go about updating my device safely?

If you are rooted then you can flash any 4.3 ROM in the android development and they all have KNOX free bases. You will most likely need to update your baseband to MJB. Enjoy your KNOX free 4.3!!!

You should first check to see if you can get an OTA update. Some users have reported being able to update OTA to 4.3 even with root. Go to Settings => About Device and check for updates. If you can't get an OTA update, you may try manually updating via cwm via the method posted in the following thread: http://forum.xda-developers.com/showthread.php?t=2658486
Before updating to 4.3, however, I would suggest you ensure you are done with taking advantage of all the opportunities you have at 4.1.1 including free unlock as you would not be able to downgrade the 4.3 bootloader once you've upgraded. If you don't have Samsung Kies installed on your PC, you may install it to back up and restore your data. In other words, you cannot go back to an older version (easily) once you have upgraded.
Hey guys,
my GN2 has 4.3 Alliance ROM atm.
I noticed that there are more 4.3+ ROMs available than 4.3 ROMs...
What do I need to do to install 4.3+ ROMs?
I think I had to unroot, install 4.3 Stock, then Jailbreak to go from 4.1.2 to 4.3.
Thanks in advance.

Jailbreak an "android" phone? Well anyways if you want to try 4.4.2 ROM all you need to do is clean wipe your phone via custom recovery and flash any of the 4.4.2 custom ROM.SuperSu is built into the ROM so you'll have root access if for some reason SuperSu crashes when you open it in app drawer just un install it via it's settings and go to playstore to update it and you are done.I am sure you aware of being on mj5 bootloader at least to get wifi working since you are on 4.3 you should have it already.Only thing is any 4.3 bootloaders wouldn't charge the phone with a 4.4.2 TW ROM on it ,it will turn on by itself when charger is plugged in.So if you are out of warranty and don't care about triggering knox when updating your bootloader. upgrade to ND3 bootloader which is 4.4.2 bootloader,but you cannot downgrade bootloader.So it's the choice you got to make which bootloader you'd like to stick to and its pros and cons.
ND3 bootloader
How to flash bootloader
Hey thanks so much for helping me out.
a few questions though.
Only thing is any 4.3 bootloaders wouldn't charge the phone with a 4.4.2 TW ROM on it ,it will turn on by itself when charger is plugged in.

I charge my phone using external charger so I never directly connect my phone to a charger. I guess this isn't a problem for me?
Can I install 4.3 ROM after installing 4.4.2?
Also what happens if I trigger know while updating my bootloader? does it brick my phone? what's remedy to triggering know?
Thanks again.

That shouldn't be a problem if you charge your battery via those external chargers.When Knox is triggered you cannot go back to 4.1.2 ROM only 4.3 and higher ROM are possible.You won't brick your phone while upgrading your bootloader you might brick it while going back to an older bootloader although chances are rare since ODIN would not flash an older bootloader it would just FAIL on you.As of now one cannot reset Knox.
I had to update to ND3 Kitkat bootloader in order to install Dr ketan's 4.4.2 V12 Rom. I still find my old 4.1.2 is much more faster and stable so I wanted to flash stock firmware but I couldn't because of the bootloader. So my question is, is it possible to downgrade the bootloader so I can use 4.1.2 again, flash mj5? If not are there things that I could try? Will there be a modified kitkat bootloader than I can install so I can downgrade?
Thanks

Bootloader can't be downgraded. Flashing older bootloader might brick your phone.
With Mobile Odin Pro some people have successfully downgraded to 4.1.2, but bootloader remains intact.

Doing it with software you may need hundreds of dollars worth of JTAG equipment with no guaranteed result. The cheapest and the most direct way is to have a repair shop to swap out the phone's EMMC, which should be under $100. Specifically state you want 4.1.2 and tell them NOT to upgrade the bootloader or ROM to 4.3 or later.
So I'm planning to switch carriers and I'm wondering how I can unlock my i747M locked to Fido that's running OctOS L 5.1.1. If I have to downgrade, how do I transfer all my current app data and pic's. Also, is it possible to keep the unlock if you were to update you phone to a higher version or install a custom ROM or install the nandroid backup you made before unlocking? Please leave me with some important things to know about while unlocking your phone if possible!
If the phone is running a 4.3 or newer bootloader, you'll have to buy an unlock code.
In order to enter the unlock code, the phone should be running a stock samsung ROM from sammobile.
I suggest creating a nandroid backup with TWRP, copy the backup to your computer, flash the stock ROM, perform a factory reset after flashing stock, unlock, flash TWRP, restore nandroid.

so, in a nutshell, i just need to downgrade my phone to a stock rom of 4.3 or below and just search up a video of how to unlock it using the keypad method?
than if i wanted to, i could use the nandroid backup i did before and flash it and still have an unlocked phone?
You cannot use the free method once the phone is running a 4.3 or newer bootloader because you cannot properly run the 4.1.1 modem on a 4.3 or 4.4.2 bootloader and the 4.3 or 4.4.2 bootloader cannot be downgraded to a 4.1.1 bootloader.
Before flashing anything, which bootloader is on the phone?

Sorry for the noob question, but how do i found out my bootloader?
If this helps, my baseband is I747MVLUFOB3
I actually just logged on to get similar clarification. I have an unlock code, but it does not work when I enter it using OctOS-M. Do I need to be on a stock rom to unlock? Can I easily jump back to a stock rom, then back again to a marshmallow rom?

From what ive heard, you have to be on a stock rom. As of google, even then, some users have problems or cant, which from what ive heard, can be fixed by downgrading to 4.3 (make sure ur bootloader is the same or your phone WILL be bricked).
Please note that this is from what ive heard and may not be accurate.
Install the Samsung phone info app from the play store as it will tell you a lot.

My boot loader seems to be the same as my baseband.
What is the bootloader version?

That sounds problematic...I am on NJ2. I am not having any luck finding anything about getting back to stock on the newest bootloader.

Do you think this one would work?

Whats a CWM anyways?
CWM is Clockworkmod with is a custom recovery. CWM is outdated as it has not been updated for quite some time. Many recent custom ROMs now require TWRP.
You may be able to software unlock the phone but you'll probaby need a UART cable and Samsung Pro tools. I don't believe Pro Tools is free.
The linked thread is from 2014 and, in 2014, many phones were running 4.1.2 which meant the phone could be downgraded to 4.1.1 using and sim unlocked using the dialler's menu options.
