(adsbygoogle = window.adsbygoogle || []).push({}); Simple, efficient, and works — that’s how jjolano puts it and well, it is what it is … mount dev_flash with read/write access on dev_blind using only two syscalls (one for mounting, one for un-mounting). Why? Maybe you want to get on PSN following one of the many guides here, or maybe you just care to experiment… Whatever the case though, you understand the risks involved when writing to flash.
You should always exercise caution when using dev_blind; dev_blind itself is safe, how you use it though, that’s on you. And it doesn’t hurt to create backups either.

Running the dev_blind pkg a second time (or rebooting) will unmount /dev_blind, restoring your read-only access to dev_flash.
