Restoring via filesystem?

[teotuf]

So when I jailbroke my 4S on 5.0.1 I used ifunbox and saved the entire filesystem (just a single copy of each of the recursive folder links) of the iphone on my computer right away before installing any tweaks/apps.

So if I run into some problem in the future with a cydia app or something - and in need of a restore before I can use SHSH blobs for the 4S or 5.1 untethered is released, what's preventing me from just copy and replacing the entire iphone system to "restore" it to the original state?

Am I missing something obvious here? I can't seem to find any info about exactly why this would/wouldn't work.

You are going to see A LOT of issues, iOS is a Database driven OS, while some stuff will work, some stuff won't have the right data structure or linkage on the database, since you are NOT suppose to do that on the first place, iOS does not know how to handel such an issues causing the OS to well pretty much freak out.

Like Maturola said, we all wish it was that easy.
Instead of restoring just copy/overwrite files with ssh.
Problem is it wont work and chances are you will be stuck at the Apple logo having to restore.
