[Q] MJ9 bootloader and knox

I got a new note 2 in india with latest android 4.3. It apparently has MJ9 bootloader. Is it that I cannot install a custom rom on this at the moment? I tried installing through ODIN but it failed and the phone showed the message "unsupported version". Then I had to recover using Kies.
Please let me know the current solution available.
Thanks!!

You can do any customization on your phone like a normal phone, but customizing it means that you have triggered the KNOX counter to 1. Thus on a stock rom you can never use KNOX if KNOX reads 1.
FYI the MK4 (bootloader) or MJ9 (babseband version) has blocked installation of any custom roms on our n7100s via odin. You cannot even downgrade to 4.1.2 official via odin, So flashing via recoveries is the only way left.
And also it is recommended that you install custom roms via Philz/TWRP/CWM recoveries to flash custom roms and everything.
Hope the lil knowledge helped.

Thanks, but I would need ODIN to install recovery also right (remember its a new phone so dont have a recovery installed)....would that be possible?...considering knox just blocks out odin

Yes ....damn

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.

Yes im on stock 4.3 but my warranty is over so it doesn't really matter I have TWRP recovery so if I want to flash a rom there is no problem ?
I made a nandroid backup in case

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 The link for the latest (may be outdated, idk...)TWRP is HERE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] bootloader question

re 7100 bootloaders
(please forgive my lack of knowledge)
i am on phoenix 17 rom currently, bootloader MJ5 (no knox as far as i understand. later bootloaders ie MK4 are knoxed IIRC)
am I understanding correctly that custom roms do not install bootloaders (ie 4.3 roms or 4.4 based on stock or leaked stock)?
and that is why it is possible to still revert backwards if one has a non knoxed BL?
do stock roms install bootloaders (via kies or odin)?
so if for some reason i installed a stock 4.3 i would then be stuck with a knoxed bootloader?
thanks for the info

-Custom Roms does NOT include bootloaders(as far as I know). I'm still in MJ5 BL even after installing DN3 4 Kitkat.
-Yup, i believe you can still revert back if you want to, as long as the bootloader does NOT have knox.
-It depends with what version you will install. Be informed by the "bootloader version" of the 4.3 stock rom that you will install(visible in sammobile). As long as the included bootloader is lower than MJ5(and NOT MK4 onwards) everything will be fine, I hope.
Hope I help. ^.^

also are any stock sammy roms available without bootloader (new ones)
if not is there a way to install a stock rom without the newer bootloader (can the necessary files EXCEPT the bootloader be extracted out of the .tar files and somehow be installed
thanks

[Q] advice on KitKat rom

Can anyone recommend a rom that is not custom which allows me to have have the official OTA kitkat update on my at&t s3. Please tell me where I would find it and if it is stable.

At this time, there is no official KitKat update for the s3. The custom kk ROMS here are ports from other devices

Do you have an i747m or i747? What bootloader is currently on your phone?

Boot into download mode and let us know what it says on the screen. The version of your bootloader will greatly influence the manner in which you restore a stock ROM on your phone.

Not at all. It just means that you do not have the 4.3 bootloader on your phone and you do not have Knox installed. Do you have any warranty left on your phone?
Installing the 4.3 OTA update will automatically install Knox and the 4.3 bootloader. The 4.3 bootloader can make it difficult to recover from a soft-bricked status.
If you want to have the OTA KK update, I recommend you flash a stock 4.1.1 ATT ROM, unlock your phone using the free method, and upgrade your phone using ATT's OTA upgrader.
If I were you, I would not load any stock ATT ROM beyond 4.1.1. Once my phone was unlocked, I would install a custom recovery and install a custom AOSP ROM such as GZ's Validus.

Thank you sooo much for your recommendation

To check your bootloader download "Terminal Emulator".
Open app, type "su" and give root rights
Close app with the " X"
Open app again
Then type "su" without the quotation marks
Then type "getprop ro.bootloader" again without the quotation marks
Look at the first line and see what it reads???
As you can see in my screenshot where it read I337UCUAMDB shows I have the MDB bootloader on my ATT S4. Yours should read something like I747xxxxxxx which will be what bootloader you have on your phone

Which is the best kitkat based rom, Gz's vladius or Cyanogenmod version C11 or is there an even better one?

I prefer Validus because it is based on aosp and I love the dark theme.

All ROMs are in the development section
As mentioned Official has not been released yet so there will be no stock KK
Please research all other choices there to find what is BEST for you
There are no shortcuts by asking the opinions of all the members here

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
Sent from my GT-N7100 using XDA Premium 4 mobile app

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.
