Hello, I wrote one day about this problem I was just wondering if anyone can help me fix this problem, anyways, I got the phone it was on Android 9 Pie, I got the notification for software update, the phone was working fine, the owner said to me that there was a motherboard issue which I neglect and I'm fully sure that it's a software problem with the latest update, I tried flashing the device with the latest firmware, the Carier ID is: INS(INDIA), however when I try to flash the phone the Odin shows me this:
<ID:0/003> Odin engine v(ID:3.1301)..

<ID:0/003> File analysis..

<ID:0/003> Total Binary size: 5716 M

<ID:0/003> param.bin

<ID:0/003> FAIL!


<ID:0/003> Complete(Write) operation failed.

<OSM> All threads completed. (succeed 0 / failed 1)

Phone also says SW REV CHECK FAIL (Bootloader) Device 7, Binary: 6 after failed ODIN install

I just want to make it stable, it isn't important is it 8,9,10 Android I just want it to work, I also can't enter the Recovery Mode to be able to do Factory Reset or access any information about the firmware, recently I discovered that it dosen't even do the bootloop, it just turns on and goes to Download Mode, any help would be great,
Thanks in advance!
