Yes, this was the first jailbreak method discovered by Luxferre. It was initially called "Smith.zip".
. To work you need also that your Recovery have test-keys, then it must be able to load zips from recovery mode.
If your phone is updated its probably patched and secured with dev-keys, but
I strongly advise against using this method, losing official updates you risk losing security patches and new features, bug fixes and everything an official update can provide you ... even support for certain certain official applications, such as WhatsApp for example.
I stayed at firmware 12 until May, but users with firmware 13 could already use a modified Jio phone's WhatsApp on Nokia 8110. I had to make further changes to my v12 rom to make it work.
In the end I managed to restore my Nokia 8110 with clean v12 partitions and managed to get the v16 update.
So I repeat:
use a secure method to install OmniSD, and not the one I listed and named EXTREME JAILBREAK.
But of course everyone is free to do what he wants, then it is useless to cry again here, on this forum. ;)
