Use you can iFunBox then. I'd give reinstalling Cydia via debian package a try first to see if that fixes the issue. If not, then you'll have to install ILEX RAT via debian package.
Cydia 1.1.8.deb download
ILEX RAT 1.100-107.deb download
OpenSSH .deb download
Then open up iFunBox with your device connected, open up the tree on the left hand side after clicking on the Classic tab on the top, and look for Cydia Auto Install. First drag the Cydia deb in there alone, reboot your device and see if that fixes the issue. Otherwise, do the same for the ILEX RAT deb as well as the OpenSSH deb (you can drop both in together) and again reboot.
Once ILEX RAT and OpenSSH are dropped in, and you've rebooted, SSH should automatically be turned on. If the next step doesn't work, reboot again and it'll be on.
Get your Wifi Data Address. If you have SBSettings, it's the Wi-Fi IP Address, which is normally 192.168.1.X. Otherwise, open up Settings > Wifi > the little blue arrow next to the connected Wifi network, and look for the first line, which is IP Address. Now download PuTTy, run it. For IP Address, enter the one that shows on your device. Then for the little bubbles under it, make sure SSH is filled in (it should be by default). Then connect. A pop-up should come up if it's your first time using PuTTy, say Yes. Then for login as, type in 'root', then press enter. For password, type in 'alpine' then press enter. You're now connected. Type in 'rat' and enter. Type in
"1", enter. Type in "N", enter. Type in "Y", enter. Type in "N", enter, then reboot or do a reset
