[Q] Going to Stock then OTA then root - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi All,
In ATT S3 i was in 4.1.2 stock. Later rooted and tried various rooms for the past several months. right now using Quantum 3.15.
Having a question on doing 4.3 update in stock.
1. Is there any benefits doing so ?
Steps i think i need to do. Please correct if im wrong.
1. Use odin and go to 4.1.2 then with Kies update to 4.3
2. Root
3. Use quantum or any other custom roms.
Is there any drawback in doing it.

Installing a 4.3 OTA update will install Knox. If you trip the Knox counter, your warranty will become void.
De-bricking with the 4.3 bootloader becomes more difficult in my opinion because you can't just use Odin to flash back to stock 4.1.1 or 4.1.2.
Some XDA members have also had difficulty rooting a stock 4.3 ROM.

If your phone is running a stock 4.3 bootloader, you cannot downgrade the bootloader, only the OS.

Do i need to downgrade my bootloader to downgrade to 4.2.1? All I want to do is revert back to 4.2.1 OS.
Do you have access to the stock AT&T 4.2.1 ROM? I looked on sammobile and couldn't find it.
You may be able to downgrade to 4.2.1 using mobile Odin but you would need root access on your current ROM.
Do you have knox on your phone? If you do, knox may interfere with obtaining root. Also, tripping the Knox counter will void any warranty left on your phone.

No i do not have access to 4.2.1 ROM that why i was asking here to see what i could do. I thought with Odin you could flash stock firmware with out being rooted. No i do not have Knox on my phone.

You don not need to be rooted to flash with Odin but you need a ROM that can be flashed via Odin. Unless AT&T released full a 4.2.1 ROM, it's unlikely you will find one on the Internet.
If you try to flash a stock ROM using desktop Odin that includes an older bootloader, you will probably brick your phone.

[q] 4.3 jellybean ota questions

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?
http://forum.xda-developers.com/showthread.php?t=2321310
http://forum.xda-developers.com/showthread.php?t=1831898
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.

Can I ask...
I've been reading thru some of these threads, and I'm coming to the conclusion that even with KitKat the bootloader is still unlocked, is this true? I have at&t version and they started locking that down with 4.3 JB.
Thanks.

This caught my eye. How is that possible with the bootloader unlock, is that just for AT&T? I am on T Mobile GS4 running 4.3 and I can see the knox counter on it 0x0 and I was informed that once updated from 4.2 to 4.3 and above the bootloader is now locked. Please clarify I would like to know. I am rooted though on stock through using this forum and have not tripped knox using this method. http://forum.xda-developers.com/showthread.php?t=2565758
I would love to find a way to install CWM without tripping the counter and trying other roms again but I here I can use bootstrap to run a custom rom, but no word on getting CWM installed without tripping the counter......unless I am wrong and I hope I am!

I think you have a definition difference. The bootloader is unlocked on the TMO S4. That is you can use the bootloader to update and install modems, roms, recoveries, etc. It is not locked and will let you do this.
However, if you use the 4.3 and above bootloader, it will set a flag if you flash a recovery. This is known as the Knox Warranty flag. And, this is what is shown on the ODIN or bootloader screen.
BTW, if you update to NB4 (Kit Kat) with a 4.3 bootloader or later, the SafeRoot method will not work. The only known rooting method at this time is the CF-Auto-Root which will trip the Knox flag. So, if you are fully stock 4.4.2 you will trip your Knox flag if you root the phone.
However, you can do it. It doesn't lock you out of doing it. It just records that you've done it.

So if Knox counter doesn't matter you can still root device..are you still able to install custom roms? or isn't that possible ATM? Trying to get rid of the severe lag 4.4.2 OTA update has bestowed upon my gf's phone.

You can flash anything you want with the TMO S4.
However, if you need to return it for warranty, they MAY check the Knox flag, and they MAY not do the warranty service for free. That hasn't been shown to be a fact, but it is the reason for the flag in the first place.
It has been stated by a few people that re-flashing back to full stock will remove the Knox flag. I cannot verify it, since I haven't tried it.

Can anyone shed some light on a couple of points? I currently have the MDL bootloader along with the NB4 modem. This all runs fine with my daily driver (LightSpeed) 4.2.2 ROM, as well as the (Insane Kit Kat) 4.4.2 I've been experimenting with. I do understand that I can't go back to the MDL bootloader if I update. Knox issues aside, is there any actual advantage to having the new bootloader? Since my warranty is running out soon anyways, I'm not too worried about tripping Knox. So, does the NB4 bootloader offer any real performance or feature advantages? Can I still run 4.2.2 or 4.3 ROMs with it, or will it limit me to 4.4.2+ ROMs? Does it impact the usage of different kernels? Thanks!

If you don't care about knox you better off going to the new bootloader ,the NB4 wifi driver is not present on the MDL bootloader so you still using the old wifi. I notice very strong wifi signal after upgrade to kitkat bootloader to flashed modem and wifi fix.The best way is to flash the NB4 firmware through Odin so you can get everything needed and go from there.
Thanks, makomek. I've been wondering about that, but haven't really found much info beyond the Knox implications. I have gotten an improvement in general phone call stability and download speed with the NB4 modem. Is what your're talking about related to the NON-HLOS.bin being installed? As I recall, that was to improve LTE, but I apparently it's actually related to WiFi. Or could be both? At least it's good to hear there are positive reasons to update the bootloader. Any idea if doing this would lock me into only using KitKat ROMs/kernels, or would 4.2/4.3 still work? Your input is much appreciated.

If your girlfriend's phone is stock, unrooted, and she took the OTA, the easiest way to get rid of lag is to factory reset. If she doesn't care about being rooted and just wants the stock rom, this is the easiest way to improve performance. Just start over. OTAs, in my opinion, are like a dirty flash.

How to have custom recovery

Hey guys its been a week since i bought the note 2 and i rooted it. But i cannot find how to flash a custom recovery tutorial anywhere. I am on jellybean 4.1 and the rest of the details (firmware etc) can be found on the screenshots attached..
I would highly appreciate if someone can send me a link to the guide for flashing.. thanks a lot in advance

Just simply flash via Odin
You can choose CWM, Philz touch or TWRP

You got two options either root your phone while being on 4.1.2 or upgrade to official Indian 4.4.2 and then root it.Ofcourse once you root your current 4.1.2 you can try custom 4.4 ROM and if you don't like it you can go back to 4.1.2 or flash a 4.3 custom ROM. To root your 4.1.2 rom read this guide.If you decide to upgrade to 4.4.2 Indian firmware download it from here.
To flash the 4.4.2 ROM on your phone download it from the above link(there are 3 links where the ROM is uploaded) ,use any of the links and download the zip file,extract it you'll get a tar file,put your phone into download mode ,open odin v3.09 on pc and flash the official stock rom by checking the AP tab on odin.You can find tutorials on youtube on how to use odin to flash official stock firmware so just look them up if you need it.Once you flash stock ROM you can root your phone via this guide.
Okay so now things to remember.If you root your 4.1.2 ROM and want to try 4.3 or 4.4 custom ROM you need to flash MJ5 bootloader in order to have working wifi.Bootloader is flashed directly on your mother board and it cannot be downgraded only be upgraded.MJ5 is the last 4.3 bootloader which is KNOX free(what is knox ,blah blah,you can read about it on google).Advantage of MJ5 is you can try 4.1.2/4.3/4.4.2 rom and your warranty and knox remain intact but if you upgrade to official 4.3 or 4.4.2 ROM you'll be on knoxed bootlooader which means you cannot downgrade to 4.1.2 anymore plus rooting a phone with knoxed bootloader will trigger knox 0x1 and your warranty if any will be void (no way yet to reset Knox).So if you have warranty on your phone then my advise is root your 4.1.2 Rom,download any 4.3 or 4.4.2 custom ROM,you wont have wifi working then flash the MJ5 bootloader from here and read this post on how to flash bootloader.
I know it's a lot of info to you but your best guide is self reading from the above links i hooked you up with.Also read comments from people cause that's how I learned I read and read a lot before i jumped the rooting bandwagon cause wanted to make sure i don't brick my phone. Ofcourse whenever in doubt STOP RIGHT THERE and ask us.Dont attempt things that you are not sure of.Good luck.
Thanks for the help

Wow that's a lot of info you provided there, thanks. I am not new to rooting as far it goes I have rooted and flashed many roms on my galaxy s advance and my micromax A87 before that. But note 2 was a flagship device so there are many complications that come along which got me confused. As for now, I have my rooted 4.1.2 stock rom along with cwm recovery flashed via rom manager. I am planning to flash either DN3 or the Xperia Z-ized rom. So my question is: do I have to flash mj5 bootloader to flash DN3 and xperia z-ized or can I directly flash it from cwm (with factory reset and necessary wipes of course)?
BTW, I have heard that knox is a security application that prohibits rooting on samsung phones. It also had a reward for $18k for those who can bypass the knox on the S5 and root it. If I am right, then I think I am fairly acquainted to knox.
Once again, thanks a lot for helping! Appreciate it

Since you are on stock 4.1.2 MJ5 is required for wifi to work.i learned 2 weeks ago that even mj5 is not required as previously thought by us at least not while flashing 4.4.2 TW rom.When you flash 4.4.2 custom ROM you wont have wifi working,then flash custom kernel like agni or nadia and wifi works flawlessly so one doesn't need to flash mj5 bootloader.I am not sure if this would work on 4.3 ROM you could try xperia z'd 4.3 custom ROM then flash a compatible 4.3 custom kernel and see if wifi works if it does you're set.This was new to most of us so I asked the person who told me about this how did he manage to do this and he told me apparently custom kernels have some sort of wifi drivers on them so when we flash custom kernels on 4.4.2 ROM wifi works but it wont work on stock kernel unless you upgrade to MJ5 and on stock kernel.MJ5 is safe to flash anyways since its knox free bootloader.
Actually 4.3 and 4.4.2 note 2 phones and others got knox on them but we found a way to disable knox after rooting our phone SuperSu disables it but knox is triggered to 0x1 and there's no way to reset KNOX since it's concerned with the motherboard of the phone which is the heart and soul of out note 2.So that bounty you might be talking about how to reset it perhaps.Even if they succeed in reversing it doesn't necessarily mean it would work on note 3 or note 2 cause of the phones being of different hardware .i don't know the technicalities of this.

Lurking around in xda and reading as much as I can and participating in discussions related to Knox.I was clueless to all this Knox and how it works.My previous phone was HTC HD2 so samsung note II was the first serious smartphone I owned so just wanted to be extra careful that I don't end up bricking my device so read and read and asked questions.

Question about downgrading from Kitkat to Jellybean on Galaxy SIII (SGH-I747M)

Before I start I will say iI did check out the search function for more than one hour and felt pretty lost amidst the technical discussion going on. I'm still reading about Android and learning so your help will be greatly appreciated.
I bought a Samsung Galaxy S3 (SGH-I747M) soon after its launch in Canada. It came with Jellybean and after a while I updated it to Kitkat using the "check for updates" area in the phones settings.
My question is basically is out possible to root the device after I updated it. Or is it possible to go back to Jellybean and then root it from Jellybean?
I have tried to flash the stock Jellybean ROM onto it and it just doesn't work at all. Odin loads stuff for 5 seconds and it fails.
Other than going back to Jellybean is there any way to Root my phone if it's on Kitkat now? I'm not concerned about warranty etc due to age of the device and it would be gone already anyways.
Thank You!

Once you are on KK, you cannot downgrade the bootloader so don't bother trying to downgrade to JB using firmware from sammobile.com. Do this may brick your phone.
Does your phone have a custom recovery? If not, you could try flashing Philz for the d2lte and install supersu from recovery.

No it does not. Thanks I'll try that. How do you install super so froom recovery and would i get root access?
Thanks so much!!!
In order to flash supersu, you will need to install a custom recovery onto your phone. Doing this will automatically void your warranty.
