Bootloop issues

Hello there. So, this is my actual situation: I have a galaxy s4 on stock Lollipop. Due a few issues, I decided to try to downgrade to kitkat I flashed via Odin a stock kk fw, but unluckyly I Haven't considered Knox bootloader, and now the phone stucks in bootloop. I tried to enter recovery, but it doesn't even work.
Is there any way to save it? Actually, I'm downloading stock lollipop firmware to flash it from Odin. Could it work ?
Thanks everyone will give help
Yes, flash the latest stock ROM in Odin to get the phone back to stock.

Flashed wrong fw

Today after i updated to android nougat I tried to flash with odin firmware (SM-G930T_1_20160704090453_jo3tv4r6ht_fac) to go from 930p to 930u but it failed, and after that my phone doesnt want to restart, when i want to trun on recovery menu it crashes after 5 sec and reboot again, i can turn on download mode and try flashing some other firmware to repair my nougat one. Anyone have nougat fw for 930p so I can flash it and make my phone work correctly, or maybe i can downgrade to lower fw. Please help me and give advice how i can fix this. Nougat was working correctly but flashing the SM-G930T_1_20160704090453_jo3tv4r6ht_fac was a mistake and I ****ed up my phone.
@edit I just flashed it with APJ2 and it is working fine again. We can close this
Was there any other people besides you that had flashed that firmware? lol i would never do that to an 800 dollar phone unless it's a community that flashed that firmware then maybe i would. Try browsing sammobile for the firmware. The software version for nougat is BQAA. Hope i helped.

A310F flash fail, Odin, brick, no 4parted firmware nougat avaailable, how to go on?

Had A310F with custom ROM, then went back to stock marshmallow.
Now wanted to go for latest Nougat with the marshmallow rooted and twrp on.
Samfirm only gives my one oart firmware which does not fir in ap slot on odin 3.12.
using 4 part nougat carrier specific not free one it fials on flashing.
What is the way now to get a stock android 7.0 device here with which firmware please?
does flash fail due to downgrade?
think i deleted something in marshmallow rom to make bootloader security somewhat fit to downgrade
Try to download the firmware from sammobile.com i think you can't downgrade just download another stock firmwaee for the a310f (your device) and try to reflash via odin

An error has occurred while updating the device software fix!

So i installed LineageOS 16.0 android 9.0 and i wanted to go back to android 8.0 and somehow i got that error. F*cked up somewhere in odin 100%. I was using lastest version of odin, so odin v3.13.1. So i tried to flash stock firmware many times, tried to flash TWRP but nothing worked. Then i started trying out older odin versions and i finally flashed the TWRP with odin v3.12.3! Now the phone works Hope this helped someone
BTW has someone a link to a not buggy version of The Galaxy Project rom? 2.2.1 maybe or something like that?

Attempting to revert back to stock firmware after bad root with Odin

I tried to root my S7 Edge about 3 days ago when something went wrong and something got corrupted. Most of stock firmware was missing after installation from looking at files inside of TWRP. Long story short, I cannot flash stock ROM back onto my S7 Edge. I keep getting complete(write) operation failed inside of Odin when I flash stock ROM onto it. The only thing that I managed to successfully flash back was stock recovery and CP but I ended up flashing back to TWRP. Flashing stock BL gives me errors regarding sboot.img.
My phone is not bricked as TWRP works fine and I managed to flash DotOS onto it as a test and it worked fine and I had no issues flashing DotOS onto it either.
My S7 Edge (SM-G935F) is a UK phone locked to O2 updated to Android 8.0.0. I tried two or three stock firmwares from SamMobile under firmwares/galaxy-s7-edge/SM-G935F/O2U/ but I keep getting Odin compeltion failed error.
