Hello. I have searched but not found any clear answer. I wonder if I have version MJ7 under AP can i then flash a older rom without problems?
Is it only if having kitkat then I can't flash older rom? Or is it even when being on jelly bean?
I ask because I need to keep knox ok but I want root. So i thought I flash a older rom and root and keep knox ok?
You won't be able to flash anything below MJ7 if that's what you currently have. And with MJ7 there is no way to root without tripping KNOX either I'm afraid.

In addition to what @radicalisto wrote earlier...
even you are in KK, you can't flash older ROM. And yes, any newer ROM which come with a new bootloader, once u flash it, most possibilities, you can't go back to earlier one.
so, if you are now on MJ7, and plan to have KK on it, I suggest you update first before you root your device.

Thank you. I thought it was possible when I am still on jelly bean. So I was wrong. Sad it's not possible to flash older.
On my Note 1 I could flash anything from jelly bean.

Hehehe.
U r on the dead end at the moment if u need to root safely, since u r on MJ7 alrd. U stay or u upgrade, if u want root result is the same.
Difference only on how many times u need to reroot.

Hi to all,
My battery is worst since i've updated to last version of firmware (UDMJ7) with the OTA way.
If I flash it with Odin, does my Knox will be enabled (0x0 -> 0x1)?
Thanks for future answers.

Yes, definitely. You won't be able to downgrade back to previous bootloader. Even if it is booted you won't have any sound and data. But you can still downgrade to MJ6 firmware where there are reported case that it is successfully done.
And regarding on your battery issue, just stating your battery is worst doesn't help. I would suggest you to download BetterBatteryStat or WakeLock Detector. Then it will give you a better statistic on what is draining your battery. In fact I find the MJ7 battery life is better than MJ1

If you want to be able to go back to a lower version of firmware if you want, root your phone with URDLV and then install MJ7 with Mobile ODIN Pro....
MOP doesn't flash bootloaders leaving you the option to try any rom you want.
Just be aware rooting with cf-autoroot, flashing custom recoveries or kernels WILL trip Knox counter.
Hey guys so i have heard that if i install the old firmware for my s4 from sammobile using Odin one from early 2013 that it will give me access to service menu so that i can unlock my phone. So my question is that is it 100% safe to Odin flash the older 4.2.2 rom when i am on 4.3? Can i flash it unlock my phone then upgrade my phone to a custom rom again? Thank you

Do not do this. This will brick your phone. If I am not mistaken, there is a method to unlock mk2 in the general section.

You should ask this in the t mobile s4 forum. I believe your bootloader is unlocked and you can flash an older firmware version. But check there first. This is the att s4 forum. It can't be done on the at&t s4.
Is the service menu missing on the stock T-mo 4.3 ?
Nooo guys i have an unlocked bootloader i have the s4 that is very similar to the tmobile and it's the same as the Canadian versions. And yes the Canadian version which is 1337m and mine which is m919v don't have access to service menus but i have flashed a lot of custom roms simply by philz recovery so doesn't that mean i have an unlocked bootloader?

If you're on 4.3 I believe you also have Knox, in which case I don't think you'll be able to go back to 4.2.2. Read through this http://forum.xda-developers.com/showthread.php?p=40903040

Did you ever take the ota to 4.3? Do you know what firmware your device is on? A 4.3 custom Rom wouldn't have knox but if you took the official update to 4.3 you would have Knox.

Idk, I'm not that familiar with your device. From the little bit of reading I've done I would say no, you can't flash an older firmware. But again, I'd post this question in the t mobile forum. They'd be more familiar with your device.

Did you ever update you device with kies or ever take an over the air update ? It's fine if you were on a stock based 4.3 rom as long as you never took an official update. If so then you can't go back. Just flashing a stock 4.3 rom won't change that status but the 4.3 bootloader would.
You would have know by checking in settings under SE

I remember i soft bricked my phone one time and had to flash my firmware but the 4.3 latest one from sammobile and after i did that i got knox but i believe i already tripped the knox counter because in download mode it says 0x1 so i guess i cant?
I have a phone which has a lot of problems after the KitKat update.
Now I want to try to reinstall KitKat. Samsung doesn't provide this, so I want to use ODIN and the firmware from SamMobile.
Does anybody know if I will do this that it will trip the Knox counter?
What if you try to just reset the phone to factory settings? I wouldn't know anything about Knox though. Hope you sort it out. :fingers-crossed:

I reinstalled my firmware and I can confirm that it indeed won't trip Knox.
As it might be useful I also want to share that updating using my Mac (with VMWare for Windows) gave me a lot of troubles. After using a native Windows laptop the update went fine.
Too bad it didn't solve my problem. Going back to the store to claim my warranty.

So forgive me if I'm asking a stupid question here but I thought that if I root my Note 3 I will automatically trip the Knox counter, even before I get anywhere near flashing a new ROM - stock or custom. Is that not true then?

You won't trip Knox if you install a KK rom but will if you try to flash bak JB.
Any form of rooting will trip Knox. There used to be safe ways that didn't but with the introduction of the newer bootloaders this is no longer guaranteed...
Have you tried backing up any info you want to keep to a pc then factory resetting, I found KK was a b!tch until I reset it due to old JB data scraps causing issues...

I'm on stock 4.3 and not having any issues at the moment - other than my Note 3 not picking up the 4G signal on 3 for some infuriating reason.
So can I flash a stock KK rom without rooting then? I'm probably being thick but thought you had to be rooted to flash any kind of ROM?

You have to be rooted to flash the custom roms provided here and that will mostly be thru recovery. It will surely trip knox. To flash stock roms from sammobile you don't need root. That can be done thru odin.

I would suggest however, if you are network locked to unlock 1st... If you need to flash a separate modem afterwards this can trip Knox as you aren't really using a "Stock rom"...
Also make sure re-activation lock is OFF.... If you go to Kitkat and you don't have a KK rom yet you are stuck with a softbricked phone until you do get the KK rom... You can't go back to JB after flashing KK rom due to a new bootloader...
As we all know attempting to roll back NAE trips knox...but it's been stated that rolling back without rolling b ask the bootloader will not trip knox...but this is unconfirmed. ..has anyone tried it? Anyone willing to?
And let's say I want to try it myself...I've never used Odin before now so how would you set it up to flash just the ROM?
If you have the true Knox Bootloader - took the OTA or flashed via Odin...
As of now you CANNOT go back to a non-knoxed bootloader.
If you wish to try what has been done, probably hundreds if not thousands of times and try - go ahead. You'll find that out.
Your question is brought up a few times a week, sometimes a day here.
"Rolling back without rolling"? As leader stated you cannot roll back via Odin to a previous OTA build. And that is not what trips Knox. Rooting doesn't even trip Knox. Its installing a custom recovery that trips Knox.

there was with 4.3 using Kingo app or Saferoot. But it seems neither have been updated to work with 4.4.2.

Sry I've read you are on Version 4.4.2. My mistake.
So you currently run Android 4.2.2. Do you have the Knox bootloader already? It is inverted to all firmware builds MGG or higher.
When you don't have the Knox bootloader you can flash everything you want to and you are still able to reset the counter with triangle away.
When you are on the new Knox bootloader i would recommend you to upgrade to the latest Android version and then use the link I posted.
