Rooting after 4.3 Update?

Firstly, Merry Christmas!
I updated to 4.3 on my stock android rom last night and tried to re-root it again this morning and (of course) ran into problems. Trying to flash a rooted stock ROM in Odin caused me to get a "failure" error (Something about Fused 2 > Binary 0, whatever that means) and since I didn't root BEFORE updating, I can't flash a stock rooted ROM through CWM - is there anything I can do to root my phone or even revert back to 4.2? I'm about to try using CF-Autoroot but I don't know how it's going to work (I've read other threads where it's been unsuccessful but I'm crossing my fingers) so if anyone could direct me to a possible solution, I'd be very grateful!
Edit: CF-Autoroot didn't work, ran into a "unsupport dev_type" error when trying to flash it through Odin.
Edit 2: Turns out I had downloaded the wrong CF Autoroot (the Canadian one) so after double-checking, problem solved!

Merry Christmas to you ! Not if you upgraded to the 4.3 OTA locked bootloader & Knox. If so, bootloader downgrade attempts will brick your GS3.
You can safely flash some roms. kernels & modems, but flash counter & warranty flag will show it.

[Q] GT-N7100 rooted on Android 4.3 Knox 0x1 can't update OTA

Hi
I am using Samsung Galaxy Note II GT-N7100
I did a mistake by not doing more research before rooting my phone and now my Knox flag is 0x1.
I upgraded my phone to Android 4.3 then rooted it with Chainfire autoroot using Odin.
Now I am not able to remove KNOX bootloader also if I try to flash a KNOX free bootloader Odin show unsupported device error and device gets soft brick then I have to flash Chainfire autoroot again to start the device again.
Is there any way to get KNOX free bootloader? or to be with Knox bootloader but everything fine like it was before.
Disadvantages are
I can't use Knox feature now.
Cannot update my device OTA or through Samsung Kies so downloading form Sammobile and flashing takes a lot of time.
I don't have any other problem I am running on stock rom 4.3 but I want that I should able to update my mobile OTA and if possible able to use KNOX feature again.
Thank you
Have a nice day

So far, this issue of 0x1 back to 0x0 is still fly high in the air. I read a lot of thread regarding this issue, until I myself also a bit headache
But, from my understanding after reading so many thread... Once it tripped, there's no way to return back. And you can't (theoritically) to revert back to 4.1.2 bootloader, but perhaps, there's a way. And yes, once it tripped, you can't use any KNOX features.
I still have no better conclusion as well regarding this issue. I got read 1 time somebody is able to revert back to 4.1.2, but still with KNOX 0x1. Most are failed. You may want to read all the thread regarding this issue with a search.
I'm here not to answer exactly on how to revert back. But just to share what I know regarding this tripping issue. To be frank... I also want to know about this, as I need to root my MJ7 Note 3, which so far... no solution yet for the tripping KNOX, so I still hold on to it.

YOu can root if you have not trip 0x1 without tripping it.

I also want to know about this said:
I found a way today on the internet that If Note 2 is at 0x0 flag you can root it without increasing the count but it will show custom that you can revert back to original by triangle away may be there is a way for Note 3 too.
I have already rooted so problem starts here

but in Software update you device is modified. May it is showing you because you have already the latest update. Please can you tell me the Device status in Downloading mode also please report back if you are able or not to download update OTA when available.
Thank you.

Same boat
My phone is in the same boat as you. My desire was not so much KNOX as to have 4.3 with phone encryption and root. In order to succeed with my desire, I have to leave the stock 4.3 recovery intact. This greatly reduces my root options. I had root before the update, but it was unable to update after going to 4.3. I tried Kingo in an attempt to fix root, but to no avail. I decided to unroot and re-root. I used Kingo to unroot. From there I had to run saferoot a few times before it was finally able to install SuperSU and associated files. The version it installed is the latest so I'll have to wait until the next release to find out if it can update. Everything else seems to work fine except ES File Explorer appears to no longer be able to mount the /system RW.
saferoot can be found over here

Super Problem!!! Need help quick please!

Ok I think I'm really f*cked.
I had installed ProBAM 1.2.4 but because I had some serious problems with data loss and not making backups properly I decided to flash official 4.1.2 and then root+install recovery and install Phoenix ROM. After trying to install the 4.1.2 from SamMobile for my carrier(Cosmote GR) using dr.ketan's instructions for stock ROM ODIN said failed. Then my phone booted up and It said something like "Corrupt Android upgrade please use emergency install using Kies". So I installed Kies, followed the instructions and my phone finally booted up, all working! Now here's the problem. I opened settings and it said I had Android 4.3(it also prompted me to make a new update/OTA). So what I want is:
*How can I downgrade to official 4.1.2? I dont care about warranty.
"*How can I reset KNOX WARRANTY AVOID: 1" ? Or at least how can I root 4.3 without tripping KNOX so that I install custom recovery and install new ROM?
Thanks in advance, really need help quick.

You and me again
1. After official update to 4.3 via Kies, afaik no more downgrade to 4.1.2 cause you flashed knox-enabled bootloader too. (Check this!)
2. At this moment there is nothing known to reset knox-counter
3. Knox counter has tripped already, therefor I recommend http://forum.xda-developers.com/showthread.php?t=2531965 to root.
Stay cool and now you are in the same situation as most people here: You can test as many custom roms as you like.

@Androidwizzard YOU ARE THE MAN!!! OMG you are SOOOOO helpful!! I love when members here are soo nice and helpful to others Anyway tomorrow I will try rooting my phone using that method(I will first for to service to replace the screen like I told you ) but now after reading so many knox threads I'm confused. Here's my question. After rooting and installing Philz recovery, can I flash MJ5 Bootloader and then Phoenix ROM? I want a KNOX free ROM Thanks again

Please check your bootloader with the app z-device, cause I think after that kies-update you should have a newer BL than MJ5 and then downgrading the BL is impossible, don't even try that (in many threads you can read about that failure!)
With the newer BL you can flash all roms 4.3+ here without even thinking about wifi and so on.

@Androidwizzard Heres what I got from z-device test
https://imageshack.com/i/0wn8lep and https://imageshack.com/i/ngyrblp
So after rooting I can flash any 4.3+ ROM without problems? And how to remove KNOX?

As I have told you: It is a newer BL! (Trying to downgrade will end in bootloop and errors).
And as mentioned in Post #2 http://forum.xda-developers.com/showthread.php?t=2531965
for me the best and easy way to root and deknox :good: if you are sure, that knox-count is x1

@Androidwizzard So first I flash Philz recovery with ODIN and then boot into recovery and flash dr.ketan's aroma tool to root and deKNOX right? Do I have to DeKNOX everytime I flash a new ROM or just once?

You do it only one time, cause custom roms are deknoxed :good:
In the moment you have an official rom with knox.

@Androidwizzard Soo(sorry for being annoying :/) Flash Philz with odin->Flash dr.ketan's tool with recovery->Root->DeKNOX->Flash Phoenix ROM

Well not really 100% sure, you need to deknox with the tool, if you flash a custom rom immediatly, but it won't be wrong, so do it that way.

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.

Help needed for unrooting

Hi guys I've had my note II for quite awhile (2 years) and I've rooted it back then installed custom ROM and recovery, not quite sure if a custom kernel is installed. Currently still on 4.1.2 and TWRP installed.
To unroot, I researched that i'll just have
Use Triangle Away and reset my counter.
Flash official firmwares from sammobile
The question here now is that do will my device be kept as official/normal and flash counter 0?? Because some of the steps shown are quite ambiguous and I just want to make sure that I can sell the phone!
Thanks in advance!!

Well, you will need to flash official firmware 4.1.2 first. The status of the phone will be official.
Then, root the phone and install + update Super SU. Use triangleaway to reset the counter.
Then, fully unroot using Super SU. Your phone should certainly fetch you a good dowry.
Press thumps up if you found this suggestion helpful.

hmm is there anywhere that I can find the official 4.1.2 firmware? Sammobile only has the latest versions.. Also, is it possible to retain root when I flash the original firmware?

Go to samsung-updates.com and click firmware archive.
There is a list of 4.1.2 firmwares. Find one for your country.
Also, if your country is not listed, you can flash 4.1.2 from any country in your region provided that your phone is Galaxy Note 2 international (N7100)
If not, you may have to settle from may be 4.3 or 4.4.
Lastly, you cannot retain root. You will have to follow the procedure mentioned in the earlier reply.
