My S2 SM-819 is having bootloop problems. It goes into bootloop on starting up. However, if it is on the charger, it simply closes down instead of bootlooping.

I want to flash with Odin a firmware to solve the problem but I can only get one single file on Sammobile. and when I try to flash the file that I downloaded from Sammobile, it does not flash normally.

I would like to get the complete firmware (PDA, Bootloader, CSC, Phone) to completely restore the firmware with Odin.

Can someone help me with this, please?

Thanks in advance!
