Do you have your shsh blobs saved?

Try going all the way back down to 4.1 as Apple is apparently still signing this firmware for 3G/3GS and a lot of members seems to be having great success with this downgrade.

I have no shsh blobs save is there a way to get shsh somewhere

shsh blobs are device specific and if you didn't save them during the signing window then there is no way to get them.

As I stated before Apple seems to be currently signing the shsh blobs for 4.1 fw on the 3g and 3gS so it may be possible to upgrade/downgrade to this fw but nothing more. If you truely want to be on 4.3.5 then that is your choice alone but heed the warning of the tethered jb and its still quite buggy.

Download directly from Apple or from here:

This will give you the 4.1 fw and you simply have to restore to it as you would any other firmware.

Restore to stock 4.1 fw and kick out again. Sometimes , you need to do it more than once

I tried like 6 with tinyumbrella and the same for recboot
