Any way to block OTA updates in the hope for future jailbreak?

[maakies]

So, I have a Scribe and I'm on 5.16.9, well past jailbreak as an option. Would like to be able to jailbreak in the future as I despise the home page. Used KOReader on my Voyage which would be much better.

I use sendtokindle, so indefinite airplane mode isn't an option.

Thank you for your time.

Fill out device storage with junk data and leave only ~100 MB of free space? So it doesn't have enough space to completely download firmware update bin file.

I'm in the same situation as maakies, and while looking for an easy way to achieve this in Windows I stumbled upon this method; I'm posting it here in the odd chance it might be helpful to someone else.

In a nutshell, I used the command below to create 64GB's worth of 10MB files, copied them over to my Scribe (in a new folder) until there was less than 10MB left, and then deleted the last 10 files copied to the Scribe to free up around 100MB.

For /L %i in (1,1,6554) do fsutil file createnew D%i.tmp 10485760

This way I can control the available space by deleting files in 10MB increments as I download more books onto the Scribe in the future.

It's obviously overkill to create the full 64GB as the OS and existing books already take space, but the creation of the files is very fast and I wasn't in the mood to compute
