This doesn't work for downgrading from CND2 - fails with SW REV. CHECK FAIL DEVICE: 3, BINARY:2. I was hoping to fix my ChromeCast issues with CND2 by downgrading.

Thanks so much for the clarifications. I guess using Odin isn't quite like flashing the BIOS on a PC, where you can flash any version, forward or back.

Nope. not that easy sometimes.

Galaxy nexus are super easy to go back n forth, but Samsung does something to thwart that. Thats the way I understand it anyways.

Thank you ... you've saved me a lot of grief. I was thinking of trying CND2 and returning to BMK1 if I didn't like it.

Frankly, I'm really confused as to why it is ok to downgrade from a custom ROM, but not from a different factory ROM. Maybe once knox is tripped, the system no longer cares what you do?

Custom Roms didnt flash bootloader. If you flash newer bootloaders, you can only go back to fws with the excact same bootloader, otherwise it failes in Odin.

Thats not totally correct. Some failed flash updates via Kies trips knox too. Ive read about some devices.
Samsung Galaxy S4 - [Android 4.4.2] - Imperium Rom
Nexus 10 - [Android 4.4.4] - My "Factory Image"
Samsung Galaxy Note 10.1 2014 - [Android 4.4.2] - my own xKat ROM
"My small Projects"

I haven't seen this. But I could see how that would happen. So just make sure you do it right? That would be the solution then? I'm not sure, I've never had a failed Odin unless I screwed something up

So theres no way to downgrade to 4.3 after going to the official 4.4.2? I'm getting nasty lines on screen sometimes while playing video.

Thanks for the explanation. I'm new to Android, so I apologize if my next question just shows my ignorance but since there are people who need to back up from KitKat...

Would it be feasible for a dev to create a version of BMK1 that used the bootloader for CND2?

Here's how I fixed the "SW Rev. Check Fail. Device:3, Binary:2" issue. I was trying to take my device back to stock root.

I had to find the post KitKat tar file (which I did on the forum here) and flash that, it would not let me go back and use the file in this thread because I had already did an OTA update so you can't go backwards, at least I couldn't. I'll try to dig up the file I used and post it here.
