Helpp pleasee, firmware upgrade problem !

Hello guys,
I have updated my G900F to 5.0 lollipop and after i saw that Kit Kat is way better i wanted to switch back to Kit Kat. When i tried to get it back to Kit Kat via Odin, it got stuck! It said Firmware upgrade problem. I solved the problem with adding PIT file i found on XDA forums. But since then i can't update OTA and can't update via Kies Please help me solve this problem. I guess it's a problem with PIT file i installed but without it i couldn't solve the problem with Firmware upgrade. After updating i also got a problem with camera sometimes failing, it starts and shows black screen. It can be solved with restart but after sometime the bug comes up again. Please help me, this is really annyoing and bugging me a lot
Why do you want to OTA if you want to stay on KK?
OTA will take you back to Lollipop
If you are rooted / custom recovery, you can not OTA

[Hard Problem] Unable to boot up after flashing

Hey guys, I got an Samsung Galaxy Note3 That really stuck on logo before flashing the device. The model number is SM-N9005. I tried to flash the device with the never version of Android and it doesn't work. I tried to flash with the older version and custom rom but it still did the same. I can't figure it out what's the problem. I hope you guys help me out with this issues. I use odin v3.0.7 and if you guys had any suggestion using the other device please let me know about it. Thanks
Just download the stock firmware for your device
Just download the stock firmware for your device from sammobile.com it's free and flash it with Odin
This will put you on 5.0 lollipop but then you can just flash twrp and install any other custom ROM and btw I think that the problem you are facing is because you didn't flash the new bootloader and modem for the ROM you tried installing.

need help please rom flashing problems

hi hope i'm in the right place, my sm-g935f had an error with an ota update and got brick with the error binary locked with frp lock or something like that. i'm trying to downgrade from oreo to mashmellow and on odin it fails as soon as i start,same goes for when i tried nougat, can someone please help the only rom that flashes is oreo
official rom you can only install the latest version. Android 6 or 7 only to custom roms ported from other devices. Blocking the bootloader does not allow you to downgrade.

It's failing when you flash in Odin because you have a higher bootloader/binary. When you try flashing 6.0 or 7.0 software eventhough it's stock Samsung firmware, your Binary number is higher than the binary on the 6 or 7.0. This is from what I've seen been talked about here and elsewhere. Do you have to Downgrade?
