Firmware downgrade Samsung J500H from MarshMallow with the second loader to LolliPop 5.1.1.

Those who are faced with the inability to roll back to version 5.1.1 are uncomfortable with using their phone.
We need to either use the Philippine firmware or install a custom firmware Belousova.

I found an acceptable way to flash my phone with a stock firmware.

1. For rollback, we need a four-file stock firmware J500HXXU1APA5 or J500HXXS1APE1.
2. File BL with the second loader BL_J500HXXU1APA5_CL958143_QB8363487_REV00_user_low_ship_MULTI_CERT.tar   or  BL_J500HXXS1APE1_CL1011281_QB9453563_REV00_user_low_ship_MULTI_CERT.tar .
3. Odin.exe.

Please note: these files for the regions: CAC, CAU, SEK, SER, SKZ.
In other regions, wi-fi or a radio module may not work.
For other regions, you need another file for a specific firmware.
If you need another region, write me the name of your firmware.
To avoid FRP blocking, you need to disable your google account before flashing.


The process of the firmware I will not describe, it is well known.
You can see video here.
