You can flash stock rom 4.2.2 through odin to downgrade. You can find the rom in the forum of I9500 or on sammobile.com. But you may face problems with IMEI. Happened to me.

I see that your baseband is MI5, is KNOX still 0x0?

Yes you can odin it, i suggest doing it through ODIN and not the mobile version. You'll have to re-root after

If KNOX is still 0x0, and you want to keep that, you MUST use Mobile Odin. With Odin and CF root KNOX will become 0x1.

In that case do what @polish_pat said. Use Odin 3.09 to flash the downloaded firmware, and root it after that.

It is 0x1, so it would be just Mobile Odin, or Odin and I should have no major issues moving to N9005VJUBMI7 ?
Once Kit Kat becomes available, would be the same?
Thanks Again

The update process should be flawless. If you want, you can also flash polish firmware and have kit kat today, then you can flash a rom like X-Note 10. But if you just want to stay stock rooted, use ODIN to flash stock firmware and re-root afterwards

Thanks, I was still doing some research as I have seen some comments regarding current KK, having lots of bugs..
But for my future reference, I would just download KK and flash it with odin as well?, what about the X-Note ROM, i will need to do some research on this one, but if you can point me on some references will be great to start, as well of know issues, or downsides of this ROM

KK has no bugs for me. As for xnote, go in dev section and look at development thread for the rom

You keep giving advice to people that have N9005 without even ****ing mentioning that you have the N900W8 phone where the bootloader (and a lot of other stuff) is different

It's the same phone! The bootloader has nothing to do with anything, its only relevant when we talk about upgrading and downgrading. The guy just wants to upgrade to KK, he can go in xnote thread and there are instructions for the upgrade, and in case you didnt know, xnote is designed for 9005 and W8 is not officially supported, so next time you try to open your little piehole, do your research first

If your having a problem with 4.4.2 , try to do a Factory reset and wipe cache via recovery.or reflash the rom once again . it might fix your problem. Have a nice day

I think you must have stock recovery in order to downgrade the modem. I am with stock recovery and knox 0 and I upgraded and then downgraded back perfectly at the first attempt each of the above (I was also using Mobile Odin Pro for that).

Be sure to download the whole firmware, and not only modems.
Download your firmware at "sammobile.com" and then flash using PDA on odin!!
