PW Jailbreak (and USBnet) without wifi

[davips]

Hello ,

I provide here the entire story as it may help someone regarding touch not working.

Spoiler:

My PW bought 10 years ago received an unconsented update last month and its touch stopped working.

I downgraded from 5.6.1.1 to 5.3.1 it through USB.
Yes, on the contrary to some reports, this is possible despite the manufacturer trying to refuse the file because the check only happens after the drive is ejected.

After draining out the battery the touch was working again.

Now I am trying to JB it to put some kind of external control/keyboard (thrgough USBnet?) to avoid the dependence on touch (just in case this is a hardware issue and not planned or neglected obsolescence via software).

My current FW is 5.3.1. Not registered. Airplane mode ON.

In this blog someone did that through menu "Update".
However my menu is grayed out.

In this post it seems the OP JB it without wifi:

FM == 5.3.1
Never connected to wifi
jailbreak == success

What am I missing?

Thanks
