Any reason for why downgrade?
If you made a nandroid backup before flashing dll7 will the bootloader be downgraded also or not?

All this, we, as the Odia owe him because he believes he is the first found the command that updates bootloader "reboot fota_bl" ... Like it or not until I truly do not know because found it in another place.

So just tell me in which place you found the command "reboot fota_bl".

I take it's one of the Russian portal users 4pda, I did not try to find out where he took it, and just made a tool. By the way, I did not say that you're not the first found it, I was only offered a tool on the basis of it, and put it in your same topic with no claims to authorship ...

I do not understand a single thing that you're so worried for the championship? You've put it out to the public without protection. Apk could do with this command and would have earned by selling for a nominal fee, but now everyone knows it already ...

APK would protect nothing, even a child can decompile it.

Believe me, most people simply buy on the market, there are many examples Triangle Awa and over..

I agree with you, but if I wanted to make money from it I would not have released the solution public and open, but I do feel credits should be given.

So, would you like to know the answer to the question I asked you, what 0x12345676 in location 0x1002080C does?

As far as I could understand from the temporary transfers bootloader partition mmcblk0p1 into section mmcstl80?

location 0x1002080C is s5p_restart_handler INFORM3 aka reboot_mode
reboot fota_bl sets MAGIC 0x12345676
when mach_board_main is executed in sboot and location 0x1002080C has 0x12345676 then it will execute pit_update_bootloader_ota, all pretty simple really.

There is also another special mode of reboot sud which sets s5p_restart_handler to 0xABCF0000 but to discuss its function would be off topic here.

OK, what happens if, at the command reboot fota_bl, the partition BOOTA1 will be filled with zeros or different words empty?

All is checked that the images are valid before any move process is done.
