[HELP] Need help flashing back to STOCK

[miki880]

My phone is a carrier-free one and it frustrated me that all the carrier-locked ones have kitkat update so I have tried to install this version of 4.4.2 (I9195XXUCNI1) on my s4 mini BE but it failed at the end at hidden.img.ext4. I then googled the error and followed the first guide that appears (can't post the link) and i ended up triggering the KNOX flag to 0x1 (phone is only 3 weeks old...) After the recovery flash, the ROM appears to be working ,though it crashes some times, now i just want to go back to the original because whenever i try to send SMS with emojis, it converts them to MMS.

Bun when i try to flash back the original ROM i get this error in ODIN :

And on the screen it says : SW REV CHECK FAIL : Fused 2 > Binary 1

Please help me... i already voided the warranty, i do not want to completely brick my phone.

First: the converting from sms to mms is normal because sms doesn't support emojis.
Secondly: the error is because kitkat has a newer bootloader than jelly bean. So you can't simply flash back an older firmware.

I used emoji keyboard on sms before with no problems...

I tried again flashing the 4.4.2 and failed again, but this time, after flashing the standard recovery i can see the carrier apps installed and it doesn't crash anymore. Also Kies now recognizes the phone.

But, if i can't revert to original with ease, can at least someone tell me what is causing the problem with the hidden file so i can flash 4.4.2 with no errors?
