S6 edge g925i stuck at samsung logo ( does any one has solutions )

My samsung s6 edge g925i has been stucking at samsung all the time and i don't know why it is happening.

I flashed with the latest stock rom 7.0 from sammobile official website and it keeps stucking at samsung all the time.

If i downgrade it then sboot . bin , param . bin will be error. Also i flashed without the sboot . bin , param . bin and downgraded but nothing happen still stucking at samsung all the time.

I also flashed it with twrp and lineage os and after that it successfully booted up . The lineage os is working but it has so many bugs in my phone that was really useless.

Bugs are sounds not working, videos are not recorded by camera only capturing the photos, phone call sound not working, battery drain so fast that was really stupid with in a 15 minutes without doing anythings. Also, the phone heated so much.

I flashed the official rom and the current binary was samsung official and system status was custom. Like the below

ODIN MODE
PRODUCT NAME: SM-G925I
CURRENT BINARY: Samsung Official
System Status: Custom
REACTIVATION LOCK: OFF
AP SWREV: B:4 K:2 S:2

So, i just wanted to flash the original rom in my galaxy s6 edge phone and when i flashed it stucks in samsung.

Questions are ?

1. Is it problem with ic.
2. Is it problem with boot
3. Did i need to repair the boot ?
4. Is it possible to repair the boot using easy jtag ?

Anyone has solutions to fix it then please answer.
