Default [Q] Converting kernel to ftf to flash via flashtool in flash mode

hello guys

just a quick question

i have noticed that when you flash stock firmware via flashtool running in flash mode it gives you an option to flash kernel or not.

so that got me thinking

i know that with my bootloader unlock status as no i cant flash another kernel but what if we was to convert the file to a flashable .ftf file.

if this can be done i think that it would help out a lot of people and would also mean people with locked bootloaders can try jb or even kitkat roms, atm i want to overclock the cpu but cant on the stock kernel.

if anyone knows of any possible way of doing it please let me know

cheers

All flashtool ftf files are signed by sony so if it is not signed by sony the device would abort the flash

As @AndroidNoob69 said. The files are signed by sony and passes a signature verification which cannot allow us to use custom ROMs as FTFs. This was possible in Xperia 2010 devices which didn't required the sign verification(or was easily bypassable) but this is not possible from Xperia 2011 series.

Cheers,
