you meant that you flashed stock 4.3 and you can not downgrade to 4.2.2?
what is written in download mode?

i guess you can not downgrade due to the 4.3 locked bootloader (like I9505 new firmwares)
did you try with odin 3.09?

Sadly it look l'ile you tôt the famous KNOX....you are not being autorhized to make modifications...
Bootloader us locked with récent firmwire on the 9505.It s the same for the 9500.
Me i have on problème on the rom Echoes.it had ben removed there us ni Knox despote the MJ5 modem

Are you flashing a ROM that matches your CSC? If not try that, I had the same problem, I flashed the stock firmware that came with my phone and it all worked out.

Hi,
It depends in what bootloader you have , Odin will not allow you to downgrade to a lower bootloader that the one you have ( stock rom)

That is because you have a newer bootloader......nothing you can do about it , sorry mate
just curious, when it's said that you can't downgrade the bootloader...presumably it means when downgrading to a lower version of android? because i tested the latest ngf1 firmware and updated bootloader and have since returned to fnb8 and phone info is now showing fnb8 bootloader again.
I wonder how each day has someone to open a new thread and ask this question
Discussed a thousand times, and most illiterate person knows that this is impossible, but there are still people who have not understood
xda has its own search

For : GT-I9500
Yes it is possible/
Just Download this firmware and flash it via odin: I9500XXUBMH1_I9500OJVBMH2_I9500XXUBMG9_HOME.tar.md5
http://d-h.st/4bG
I tested it myself and worked fine.
judging by http://forum.xda-developers.com/galaxy-s4/help/imei-null-t2806504
he has i9505
and so I wrote the previous post

to be fair, the search feature is pretty lousy :\
number of times i've wanted to find something on xda, use the forums' search function and it basically displays EVERY thread in the forum. It doesn't do a great job of actually narrowing down what you're looking for. But what I tend to do now is just use google and type XDA at the beginning of my search. e.g. these are the result for "philz recovery" in the search feature http://forum.xda-developers.com/search.php?searchid=288653448
now do the same in google https://www.google.co.uk/?gfe_rd=cr&ei=BsS6U8CcJ67Y8gfQjYDoBQ&gws_rd=ssl#q=xda+philz+recovery+9505
it's the first result and takes you right to the thread.
the forum search leaves a lot to be desired, so I kinda get why people struggle finding thing on here :s

Hi ,
Knox is trip so i guess you do not flash the "knox free bootloader" from 4.2.2 so in practice you only flash a modify stock rom......
You can remove KNOX with the removal script.

There's a downgrade bootloader available in the Note 3 Developer Discussion's KNOX thread. Go check that out. Look for the guy called RuchRa or something.

I cannot download the firmware.
Sammobile.com download works for me. Maybe try this: http://samsung-updates.com/device/?id=GT-I9505

I found the firmware, but there is no download link.
sammobile.com looks to be updating their system so download don't appear to be available. You may have to try later.
Any particular reason you need 4.3?

Not really urgent, I want to download that software, just in case I want to downgrade my device.
If the phone is running a 4.4.2 bootloader or newer, I don't think you can downgrade.

what should i do if want to downgradde to 4.3 ??
tq..
You can downgrade the ROM to 4.3 but you can't downgrade the bootloader to 4.3. The 4.3 ROM would have to be a custom ROM, not stock.
