Default [Q] Permanent root with locked bootloader

I saw two different threads and thought that they could be used jointly to get permanent root with a locked bootloader, can't try on my own, need suggestions first

The above post lets 4.4.x devices get temporary root without system write access, after getting temporary root, can safestrap be used to get permanent root?

I ain't trying because I am not good at handling these things and may as I well brick my device
Can someone try it?
