SM-N750 dead boot repair

Hi ATF Team

I have Samsung SM-N750 Galaxy Note 3 Neo (sn RF1F307RMGN) in dead condition. I don't know it's history.

It's based on Exynos 5 Hexa 5260 cpu and below are links to pcb pictures

I did sdc file based on this firmware N750XXUANAD_SERANAD 4.3 but phone don't enter in download mode. Maybe it needs tp connection but don't know where to find it.

Also don't know if it's important what fw version was in phone before it died, eg. can I repair with sdc in 4.3 version if in phone was 4.4.2 befor it died?

Hope you can help me.

Thanks
