want to install stock firmware in cyanogen Samsung s5

[AC Question]

I bought second hand samsung s5 from my friend which showed its model as SM-G900F and android version as 4.4.2.
I didnot have latest firmware in my country so I thought of updating it myself via odin but soft bricked my phone (stuck on samsung logo). Then used recovery to intall cyanogen and gapps from sdcard. Now my phone says its SM-G900T not F version. It is working fine on CM13 but I now want to install latest stock release from sammobile of version 6.0.1 and model SM900F but odin is giving error----- after NAND write start, it says FAIL. Please help restore original firmware to my S5

A fail after a NAND write is usually a sign of a hardware failure.

so does this mean there is no way around without sending my phone to repair shop?
