    I want to downgrade to 4.2.8 and not get an infinite restore loop. Should i start TinyUmbrella, uncheck request from Cydia and set to Cydia on exit, then click save SHSH then use Pwnage tool to build an IPSW then start SHSH then restore with the custom IPSW?
    Did i miss something?
    Do i need to recheck request from Cydia and or set host to Cydia on exit at some point?

    If you have the shsh, you shouldn't need to build a custom ipsw. You should just be able to click the restore server in TU and do a shift+restore in iTunes, selecting the older firmware.

    Wait for confirmation on this, though. I have no idea if it encompasses all of the steps. I've never done a restore to an older firmware.

    apparently, im out of luck. someone in irc told me that i cant go to 4.2.8 if i didnt save my shsh when i first got my phone, before i upgraded to 4.2.10. how was i supposed to know to save my shsh if i was new to the whole jailbreaking thing?

    I figured it out by chance, but yes. You will not be able to downgrade if you don't have your shsh saved.
