Need some help with downgrade

All,

due to unfortunate circumstances my phonoe was upgraded to 4.2.9..

i have my shsh save to my local machine and to cydia,,

on my local machine in the .shsh directory i have
the following..

-rw-r--r-- 1 root staff 4811 Apr 16 20:18 3911391829423-iphone3,3-4.2.6.shsh
-rw-r--r-- 1 root staff 4811 Mar 6 08:34 3911391829423-iphone4cdma-4.2.6.shsh


i am not sure what the 3911391829423 relates too but, i have never
hooked up a different iphone to this mac..

my /etc/hosts file looks like this..

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
192.168.1.6 windows7
#74.208.10.249 gs.apple.com
#127.0.0.1 gs.apple.com
#74.208.105.171 gs.apple.com

here are the procedures i have tried...


1. hook up phone
2.launch tiny umbrella
3. in tiny umbrella i can see the following..
>07/20/2011 18:10:01.370 Found [2] shsh files to cache...
>07/20/2011 18:10:01.374 Cached [2] shsh files

4. in tiny umbrella start the tss server
(this uncomments the 127.0.0.1 localhost entry)

5. restart itunes and then hit alt/restore and
point it to 4.2.6 which i downloaded..

it starts the restore but fails with unknown error 20


second procedure i have tried is to uncomment
#74.208.10.249 gs.apple.com

and attempt recovery and i still get unknon error 20
as well as uncomment #74.208.105.171 gs.apple.com


i can only manage to get error code 20....


anyone have any ideas?


Greatly Appreciated

all,

forgot to mention, but i do remove (uncomment) the # before the entries entries..

should i be putting the phone in DFU mode?

Thank You
