Help/Support From cydia "not enough space" problem to all IOS apps disappearing problem

[Dav0O7 32 iPhone SE 11.4]

I was using iphone 5, IOS 10.3.3, 16 GB, No SIM card inside.

So firstly i tried to install a tweak from Cydia last night (it was a while since i used cydia to install something), it gave me errors mentioned in this topic -> 

I searched it in many places and found out that i need to free up some space. Stashing didnt work, cause my ios is 10.3.3 and it doesnt support, couldnt install any other tweak from cydia because of the same problem (even when i uninstalled some tweaks), so dont know why but i used Second Method (2:17) in this video to try "fixing" it. ->

it "refreshed" Cydia and had 2 essential upgrades to do ( one of them was Cydia installer, dont remember the other one ). I tried to upgrade them to find out if the problem was solved (i was trying to upgrade before trying any "fixing" method and it was giving the same error), but dont remember what happened, Cydia closed and all installed tweaks and all IOS main apps like AppStore, Settings, Safari , etc. disappeared. 

i tried both "Updating" and ''restoring" commands in Itunes to fix it, but it said my iphone is protected with code. Then tried to "Reset my phone" with iMazing app, it seemed to work, and this was showing on my phone -> 

but as soon as it reached the end ( its like 2-3 pixels from being fully filled), got stuck. I waited for a while thinking its fine and will do its work, after a while iMazing told to put SIM card in, but when i inserted my main Phone's SIM, it changed into message saying that connection between phone and computer was lost. After that iphone remained stuck on that screen and nothing else happened. I can still restart and bring it back to situation with no IOS main apps and Cydia available ( yeah and also cant open any other app, which is not gone  ).
