    ocnbrze DON'T PANIC!!!!!!!!!

    Can you boot into recovery? If so you might be able to just reflash the CORRECT firmware.

    Well obviously i have tried, but as its known, if u flash the wrong firmware, the phone wont even boot in recovery, neither bootloader, because of the wrong BL file
    I filled the BL, AP, CP and CSC with the wrong files by accident. I have been searching all day for a fix but the only way i find is to buy a new hardware piece, i just need to know if its emmc or any type of memory or the motherboard because that part i dont really know which hardware piece does recieve which files, all i know of hardware is to replace when its broken

    If anyone can send me a link to buy a new motherboard or wtv piece does receive the firmware or bootloader, I'd thank a lot

    If you're not able to boot up into Recovery nor Download mode, there's a good chance you hard-bricked this phone. A likely option is to drop the phone off at a trusted service shop to see if they can restore it to working condition again. Otherwise, you should start looking into getting a new phone.
    Weigh the cost of a new phone in a direct comparison to buying a replacement logic board plus all the labor, time, and effort that's going to be required. It's not gong to be just a simple process where you unscrew a few fasteners, pull out the old board, and reverse the process. You're going to have to force the casing open, and then deal with various physical fasteners along with a lot of glues and adhesives. And that's both the disassembly and reassembly. Then you still need to go through the process of flashing a correct ROM to install a working operating system, and hopefully you have previously backed up your data so you'll be able to restore your user account.

    Odin won't even let you flash a different model's firmware - it would simply fail. So however you did it, it wasn't via Odin

    Given what you've posted, I think it's truly bricked and you're SOL. Unless you have the correct JTAG rig and software. JTAG is what the manufacturer uses for the initial firmware load on blank chips during production. .

    Ebay? ...as long as the board still works and hasn't been IMEI, MEID ESN carrier blacklisted.

    Swappa's Boneyard has sometimes been recommended on AF. But apart from Ebay, the only other place I know that might have good clean boards and other spares, would be a visit to the Huaqiangbei Electronics Market, Shenzhen City, China. and that's it. Many components that are recovered from the world's recycled phones, tablets, laptops, etc. are bought and sold here.
