ipt 4 restore 4.3.3 problem from 4.3.5?..without 4.3.3 SHSH

[victor6895]

小弟 ipod touch 4 係4.3.5 downgrade 到 4.3.3 時出現問題
我都爬左文....etc/hosts
個度我加左野都係唔得....兩個host server number 我都加過,,都仲係3194
呢個情況我之前都fix 過,,唔知點解而家唔得..
唔通個host 死左,,冇運作?
what can i do?

求命呀.....用itunes 就 3194 erroe
用tinyumbrella tts server 再用itunes 就 2005 error
help....................!!!

本身部ipt 4 係 4.2.1 之後upgrade 到 4.3.5.
其實係咪冇冇4.3.3 shsh 就一定唔得?
