[Q] can i flash older roms on my GS3 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Ok so i am on 4.3 with bootloaders and modem, with a 4.3 rom
is it safe for me to flash a 4.1.2 rom and still keep the same modem and bootloader.
so for example i am rooted running a stock rom with a custom recovery, and i want to flash the rom 4.1.2 Axis (SDS) rom will it be safe for me to do so or do i risk the possibility of bricking my device.
NOTE:
I have bricked my device and used a method posted i think in the general forums of the gs3 to unbrick it, so if possible don't want to go through that experience again if you know what i mean

Yes, it's safe - Just make sure you don't flash a older modem/baseband or bootloaders. Although, there's no reason to go back to 4.1.2, it was awful for our device. Then again, it's your decision!

Ok i just wasnt sure and i liked the rom because i had a fantastic experience with battery life and performance. Plus it has the v6 supercharger script which i dont know how to setup on any other rom my self

Update to 4.3 Stock ROM, NO KNOX

I was wondering how would I do this. I wanted to flash JediMaster X but im rooted on 4.1.2 Jedi X. How would i go about updating to stock 4.3 without installing knox so i can get the working bootloader then update to Jedi Master X ?
I would prefer if the stock ROM was rooted already and knox removed. Anyway have any links.
Has anyone done this process ?

Hi, even though you are on stock 4.1.2, remember: you have root privileges now. You can flash any ROM designed/built for your particular variant of the Note 2. That simply means stick with flashing ROM that match your device's model number.
Next, I flashed JediMasterX this morning. It is built from stock firmware Android 4.3 for the Note2 so you can flash this ROM, if there's a build for your variant. You don't need to flash the actual firmware to upgrade to 4.3 ROM. All builds in the forum come from source code, which means there is a base design for each kind of phone, but Android is Android and it follows certain predetermined rules.
One thing you need to do is read the OP to whichever ROM it is you are thinking about flashing. The ROM chef is going to place some very important information on the first page where they present their ROM. It is much advised that you follow those guidelines down to the letter. For instance, you want to flash JediMasterX, right? Did you know that the OP mentions that if you haven't already updated to 4.3, (BTW...there are links in the forums for each carrier to download the stock firmware and they're already root and you don't have Knox to worry about!) that you should flash a particular kernel after flashing the ROM. You'll even find a link to the stock 4.3 modem, which is necessary for providing a data connection. That is less necessary than flashing the kernel and the OP explains why.
I hope this has helped. Make sure you have your custom recovery set-up and that you already have a Nandroid backup of your root stock firmware or another ROM you have recently flashed. Always keep a backup, more than one is even better!
Happy Flashing!

Yes I want to flash JediMaster X but I heard that if i don't have the stock bootloader WiFi will be dropping in and out. Support for devil kernel in V2 is being dropped or something (so i wanted a solution in which i don't have to flash devil kernel) so I need to have the stock bootloader to have stable connection. Yeah I was just looking for the simplest process to get everything working on JediMasterX 4.3

I totally understand you. And that's where that kernel I mentioned comes in. It's called the dual-boot or Devil's kernel by @DerTeufel You need to either flash that kernel after flashing the ROM via the Aroma installer. Reboot back into recovery and flash the kernel OR flash the bootloader patch provided by another senior contributor in the forum. That link is somewhere in the OP and you have this option. Download and flash the stock root 4.3 firmware -- it already is Knox free -- for your device. Then flash your downloaded JediMasterX ROM and you won't need to worry about flashing the kernel.

Ok thanks I will go the stock method way. After flashing stock do i ed to wipe data and cache ? Also is the best way to flash stock to use PC odin or mobile odin ?

I forgot to mention one other thing. I know that JediMasterX was shared with us earlier in December. One thing of interest, and this is solely for your information...don't go trying it until you're more comfortable with flashing and more importantly recovery! The N7105 is compatible with the T889 and that allows us to flash ROM built for our respective variants. The Devil's kernel was built for the N7105 originally. And I just downloaded a pretty updated -- as of this month -- version of the kernel yesterday. I did read in @DerTeufel's OP for the Devil's kernel that he wouldn't be supporting any requests for changes to the kernel. But the kernel is solid. Has been for quite some time!
Sorry it's taken me long to reply. Wouldn't you know my phones are both drained and I hadn't turned on my computer yet. Anyway, important thing is to read, read, read. I know you might get bored clicking through pages, but it's really cool when you find updates to certain ROM you like buried in those pages instead of posted on the main page. Or you find tips to a having a better experience on the ROM you happen to be on by using a mod listed in a forum. And you can learn a whole lot from everyone in these forums, but reading through the forums will teach you things about root, what you can and cannot do, that no single person can.
Hope this helped! Have fun flashing!

Yea, you're going to download and flash through desktop Odin the stock root 4.3 firmware. You download the zip, unzip and place the .md5 file in PDA of Odin. You'll then need to flash a recovery image through Odin as well so your recovery partition will be ready to flash into recovery and then backup the stock root firmware. Keep it in case you want to go back. And always do a complete wipe in recovery for a clean install of any ROM you flash.
Computer is super slow today. ARgH! lol

I know what you mean and I'm using the official ROM now without Knox
Step 1: Root your phone
Step 2: Install Titanium Backup pro (u can download the APK from apkmania or any other site)
Step 3: Find the apps in the screenshot from Chrome to Mobile life
Step 4: back up each one of them (in case if u need Knox later)
Step 5: uninstall
Step 6: have fun, your phone is Knox free

I want to know what does it mean when im in odin mode and I see
qualcomm secureboot enable.... and bootloader rp swrev :1 what does it means actually ? I try to find information but it's not clear i dont want to install a custom rom and brick my phone ...
i have so many question ...
if I install a custom rom does my boot loader have to be unlock or i shouldn't care ?
I do i check if my bootloader is unlock ?
Is the carrier is important when you put a custom rom ?
where I can find the gapps file made for my phone ?
1 rom that interest me is wicked sensation rom http://forum.xda-developers.com/showthread.php?t=2286350 it look so sick but once again it says for at&t can I install it if im with rogers because they are the same model ?
it's some little tecnical question that I have can some one help me
Are you on stock Rogers 4.3? If you are, loading a custom recovery will void the warranty by tripping the Knox counter.
If you have no warranty and just want to install a custom ROM, you can install a custom recovery via Odin and flash the ROM you want.

I prefer Philz Touch which is based on CWM because I had problems flashing with TWRP.
There should be no problem as long as the ROM is supported by TWRP.

You shouldn't just go around flashing all the ROMs you think look or sound cool. I would suggest doing your research beforehand. For example, if you want to install the newer KitKat ROMs, you HAVE to be on a JellyBean bootloader. Click HERE for the bootloader guide if you need it.
Also, your TWRP should always be up to date. The link for the latest (may be outdated, idk...)TWRP is HERE
Lastly, if you ever run into any problems and want to go back to stock, or you just want to start fresh and start from scratch, then use this. This has never failed on me. Click HERE
Remember, YMMV.
Best of luck!
I don't think you need a 4.3 bootloader for all ROMs. I have loaded Cyanfox, CM11, and Vidalus which are all 4.4.2 ROMs without issue. I personally prefer to stay away from the 4.3 bootloader because I want the ability to return my phone to stock for warranty purposes.
The OP is running 4.3 stock and the link you provided could brick his phone.

I never said that the OP needed to update his bootloader, I was just mentioning as an example if he wanted to then he would probably need to if he wanted to flash a KitKat ROM.
But you are right, for him, I would stay away from 4.3 since you can't downgrade.

[Q] Just got stock Note 2 and I WANNA ROOT Without Changing to 4.3 Bootloader

Hey guys, I just joined the club. I have a stock, never been rooted Note 2 and I want all that 4.3 or 4.4 goodness with Air Command
I've read a little bit and it seems that I should never upgrade this OTA because if I did, It would install a new bootloader with KNOX.
Since I still have the 4.1.2 bootloader, any chance I can root without installing 4.3 bootloader so that I can go back to 4.1.2 stock when I want to sell the Note 2 when Note 4 comes in.
Can you guys recommend a 4.3 or 4.4 ROM that won't change my bootloader and will also give me the AirCommand function and apps (I really want Quickmemo). Oh and any ROMs that extend battery life and streamline BloatWiz is very welcome.
my battery is draining more than I like with Bloatwiz
Thanks in advance

Few options.
1) Flash Mrrobinsons stock 4,3 using mobile odin pro and then flash the wifi patch or devil kernel.
2) If you do not have mobile odin pro you can flash the stock Rooted odin image which is packed with 4.1.2 bootloader from here.
3) You can basically flash any 4,4 ROM just make sure it does not come with bootloader (Most custom roms dont include), make sure to read the compatibility notes.

Do any of those come with Air Command? Do they streamline Bloatwiz? and since I will flash with the 4.1.2 bootloader intact, does that mean I can go back to 4.1.2 stock when I'm about to sell my Note 2?

They are stock 4.3 images and they do not come with Air command, you may try DN3 ROM but again read the OP to ensure compatibility with 4.2.1 bootloader. Yes, you can go back to 4.1.2.

From my understanding only Kies, OTA, or Odin/Heimdall (PC version) will touch the bootloader. Flashing in recovery shouldn't mess with it.
4.3 roms on the 4.1.2 bootloader need either a custom kernel such as Devil Kernel or the bootloader patch flashed via PC Odin or Heimdall to allow wifi to work. The patch can be overwritten by odin flashing 4.1.2 roms etc. Once 4.3 had been kies, OTA, or Odined the 4.3 bootloader is set.

Yeah I'm pretty confused lol. Can someone make sense of this for me. Are all 4.3 ROMs gonna knock out my wifi and require me to reinstall a patch?
Any recommendations on 4.3 or 4.4 patches that can elongate battery life without killing my 4.1.2 bootloader. I NEED to be able to sell this phone like I never rooted it

No I mean after I've rooted it. I figure whoever I might sell it would know how to access the bootloader and see that its got KNOX and has already gotten the counter

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

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.

[Q] Noob needing to go back to stock, help please?

I figure instead of pulling my hair out for three days wading through various methods and likely brick, I'd swallow my pride and ask.
Here's where I'm at: I rooted and flashed Carbon rom way back when, everything was working alright, but with time, things are slowly starting to come apart. Yesterday, it's come to the point it can't be ignored. My nightly is ridiculously out of date, but I just haven't wanted to mess with it anymore. I'm about ready to get a new phone and I want everything back to fresh stock to give to a family member. I don't know where to start and what instructions are applicable or out of date. Model: I747, Android version: 4.4.2
I think I'm done experimenting with the rooting business, it's been a ride. If I could get some clear instructions on getting this phone back to stock, I'd be eternally grateful.
Help me xda community, you're my only hope.
What bootloader is on your phone? This is important to know before trying to get back to a stock ATT ROM.

Hey there, thanks for replying! Bootloader says I747UCUEMJB.
Since you are on an mjb bootloader, that means you had the ATT stock 4.3 ROM on the phone.
Unfortunately, ATT never realased a stock 4.3 ROM or 4.4.2 ROM. These were only available via OTA.
There was a thread where a stock mjb ROM was compiled for flashing in Odin, but for some members, the flash resulted in a bricked phone.
I had a feeling that might be the case. What are my options here?
I would install a custom recovery and flash a custom rom. There are custom ROMs based on stock Samsung ROMs.

This is the way to go. Since you most likely already have a custom recovery (assumed since you are running Carbon but verify first though), then it is just a matter of getting a new ROM. There are several custom TW ROMs based on 4.3 MJB. If you really want KK, you can flash the NE4 bootloader and modem along with a custom NE4 TW KK ROM. Please keep in mind that with both MJB and NE4 (KK) if you try to revert bootloaders, you will brick.
I am personally running S3RX 4.3 and have few to no issues other than what most people experience on stock anyway. Just have not had the time to move forward to KK as of yet.

Okay, so the bootloader is 4.3, but the Android version in settings says 4.4.2, how does that fit together? Just trying to understand what all this works.
Recovery is currently ClockworkMod. Since I'm planning on giving it to family, I'd like something that is as stable as possible, nothing fancy needed. What ROM would fulfill those needs?

Sounds like you are running a custom KK ROM in order to be using the 4.3 bootloader. A stock KK ATT ROM will not run on a 4.3 bootloader.
Before flashing to a custom KK ROM, make sure you are running the latest CWM. Carbon is a good ROM and should have reached a milestone build.

You are running the official 4.3 bootloader but an AOSP custom ROM. In the case of AOSP ROMs you can typically do this. As mention by audit13, if it was a custom ROM based off TW AT&T stock, you would only be able to run a modified TW 4.3 ROM.
