I read somewhere that flashing custom rom or custom kernel trips knox? Is this true?
Ive tried searching but couldnt find no real answer to my question.
Yes that will trip the KNOX counter...
KNOX flag will be tripped if you flash custom kernel or recovery. ROM installation may or may not trip it, depends on the ROM and how you flash it.
So what is the point of not trying to trip knox while rooting if custom roms and kernels trip knox anyways?

Hi all,
is there any possibility to downgrade s4 firmware from 4.4.2 to 4.3 or 4.2.2? Even activating knox counter.
i need to reflash on my s4 gt-i9505 the non contain knox-bootloader firmware. Is there any possibility?
Thanks to all you
From what I understand, the bootloader part (as downgrade from 4.3/4.4 to 4.2) is impossible, but firmware, I think it can be done, but maybe need custom CWM flashable one
Once you have the Knox bootloader, there is no going back.
Flashing other non official ROMS and downgrading is possible, but it will all trigger the KNOX security flag. Make sure the ROMs you are flashing has the KNOX bootloader, or is compatible with the KNOX bootloader, or you will lose a lot of functions.
could u pls link it to me?

Flashing stock firmware shouldn't trip knox I changed my o2 firmware for the generic BTU firmware and it didn't trip knox, flashing custom roms, custom recovery etc will trip it.

No. Flashing stock firmware will not increment Knox.
The exception might be trying to downgrade a Kitkat bootloader e.g. trying to revert 4.4.2+ to a version before 4.3. An attempted downgrade may soft brick yoir phone and change Knox in the process. Also those with locked bootloaders i.e. ATT, Verizon, Sprint, USC should not attempt flashing firmware from foreign carriers.
Normally only a custom kernel or recovery will increment Knox. It is possible that a bad flash e.g. power interruption or (rarely) a random glitch could corrupt Knox as well.

I have the i9505 running CM11 at the moment without any knox tripped since I flash everything via recovery and I'm planning to sell the phone so I want to revert back to stock ROM so the phone can receive OTA without tripping knox, is there a way?

Hi,
If you flash an stock rom with Odin will not trip knox. It will be like factory new...as long as knox has not been trip previously
Hi,
I'm new to the custom roms and would like to see advice on the recommended method to install a custom rom onto my untouched I9505. It's currently running Lollipop 5.0.1, I9505XXUHOE4 with KNOX 2.3
Thank you
This would belong into the Q&A section.
Anyway, the first thing you will need to do is to install a custom recovery. I recommed TWRP.
Just google twrp s4.
Optional: if you want to backup any apps or data, you will have to root first. Use odin and cf auto root.
After you installed a custom recovery, just look for a rom that interests you and flash it. Every rom has flash instructions.
Also check to make sure your phone doesn't have a locked bootloader. If it does, things are going to get complicated. If it doesn't, then you're good to go. AT&T and Verizon lock the bootloaders.
Thanks for info GDReaper.
My concern here is KNOX. Will the new bootloader affect anything on the custom roms as compared to a pre KNOX bootloader. Do I need to downgrade the firmware first?
Thanks
Hi @elus,
Installing any custom firmware will trip Knox. You can't downgrade it to pre-Knox bootloader.
Sent from my GT-I9500
Knox will not affect anything. Flashing custom firmware will only trip knox. This means that you lose your warranty. But the warranty is crap anyway, so it doesn't matter.
You won't see any trace of knox in custom roms. You might as well forget you ever had something called knox.
An easy way to root the ROM with TWRP is to flash supersu.zip from TWRP. Upon first boot, open supersu and let it disable knox and update binary files if necessary. You should be fine from that point forward.
Great! Thanks guys for the guide. Let the custom rom mods begin! Happy New Year Everybody!
