well, for those who don't have their SHSH on saurik's server, or just aren't sure. there's a little app called 'tinyumbrella' which allows you to still upload your 3.1.2, 3.1.3 blobs to cydia's servers.
i'm not sure if i can post this link: Getting 3.1.3 SHSH Signature Files for Your iPhone Running on 3.1.2 | jailbreak
but that's how you can still get your shsh's on there. i had my 3.1.3 on file, but used this method to get my 3.1.2 on there too. now my 3gs is on 3.1.2.

i tried to downgrade ios 4 to 3.1.2 using saurik blob and get error 1015 then ran redsnow 9.4 which works but i get no reception since the modem is 5 13 04 now and i tried to black rain it and it says it wont work missing some file v7.dll or something and just crashes after that.
tried to install 3.1.3 firmware and i still get error 1015 but couldnt get pass that part since i dont know if theres a redsnow or pwn tool to kick it out of that recovery phase
lleb usb and ileb or something and irecovery wont detect nothing and keeps screwing up my usb drives

Hey, lets try this maybe? Doing it on a iTunes 9.1 computer? Spirit doesnt even support 9.2....i went from 3.1.2 to 4.0 [final] back to 3.1.2 with error 1600, i believe, did the irecovery(messes with usbs so if you have laptop, do it on that then uninstall libusb(if windows, i dont know about mac)) and then i activated it, then spirit. Flawless. though on t-mobile i cant use maps over edge without data plan anymore and my mms does what i posted on page 4 that no one cared to look at. Hope this helps. Oh! I am 3GS New Boot, 32 GB, 3.1.2 with modem firmware 5.13.04. Hope this helps
if you require an unlock.... where have you been???? 5.13.04 is unlockable... ultrasn0w

So I had 3.1.3 before I upgraded to 4.0. Is it even possible to down grade to 3.1.2?

this sounds a lot of hassle i may wait cause i dont even know if i can downgrade from 3.1.3 with shsh on file ?
06-25-2010, 12:42 PM #129
is it possible to use tinyumbrella even when youve already upgraded to ios4? or let me rephrase this is there any ay to downgrade from ios 4 without prior planning or prep??
06-25-2010, 01:36 PM #130
06-25-2010, 01:49 PM #131
so i can get back to 3.1.3 without having ever been jailbroke?
on a 3gs?

yes, you should be able to. but you're better off going to 3.1.2. then jailbreaking with sn0wbreeze. then you can use sn0wbreeze again to create your ios 4 ipsw and update to a jailbreaked ios 4.
but you need to use tinyumbrella to upload your SHSH to cydia's servers.

I have a 3gs and did the record on Cydia. I made changes to "hosts" file but...it would not let me save it?????
I used Pawage yeterday but did it wrong...ended up with the Apple 4.0 :-/
Have been trying everything to get back so I could have Cydia back even if I lost the unlock...HELP!!!!

my host file:
# Copyright (c) 1993-2006 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 220.127.116.11 rhino.acme.com # source server
# 18.104.22.168 x.acme.com # x client host

@dynasty: that means there is no SHSH on file for you. Or, your hosts file isn't working. What other files are in your drivers/ect folder? There souls only be one hosts file. And it shouldn't be a text file.
There should** only be.
Ps. How do I edit my post with my iPhone? Don't see the option.
Nice, it does it automatically.
