I upgrated my ipad(jailbroken 5.1.1) directly by itunes :( it works quite well. But now, id like to downgrade to 6.1.2. i did everthing but still cant fix "3194" problem.
run TinyUmbrella / save shsh / start TSS server
run itunes / shift + restore ipad / choose '6.1.2' file
Edited "host" file...
Tried with DFU mode...
Im struggling with it for 5hrs.
