I got an iPad 1g wifi+3g 64g it had 4.3.5 firmware.
Windows 7 (64bit)
I downloaded redsnow 0.9.8b4 and iOS 4.3.4 & 4.3.5 and jailbroke using the 4.3.4 firmware method. It work fine and I had been using it for a few weeks. I wanted to use wifi-sync but found that I needed to down grade iTunes from 10.4.1.10 to 10.0 inorder for it to work. So I downgraded iTunes to 10.0 I ended up not messing with wifi sync. I decided to try to downgrade firmware to 4.3.3 so I could have an untethered Jailbreak. I did tons of reading and searching google. I reinstalled 10.4.1.10 I downloaded iOS 4.3.3 with Internet Explorer and changed the file ext from .zip to .ipsw. I also downloaded a buch of .exe file that I would/might need.
List of files I downloaded:
ipsw files downloaded:
I then followed the downgrading "how-to that" on Redmondpie that said to change the host file.
This the host file that I used for this:
# Copyright (c) 1993-2009 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:
# 126.96.36.199 rhino.acme.com # source server
# 188.8.131.52 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
I got an iTunes error code of 21. After searching on Google I found something about adding another server id to the host file (184.108.40.206 gs.apple.com) I tried with the # in front of it and with out the # no luck.
Got code 3194 this time. Found that I needed to have tinyunmbrellas TSS server running. Did that. Still got error 3194 tried rebooting computer and a few other random "fixes" that didn't work. I eventually changed the host file back to origninal and did a full iTunes restore to their current iOS 4.3.5. Jailbroke with redsn0w and saved shsh blobs in Tinyumbrellas. Tried downgrade again with TSS server running. Eventually I got it to work sort of. I think iTunes downgraded it because it showed it as working normal on iTunes and showed the current firmware as 4.3.3. but iPad was stuck in recovery mode. I went back to Google and tried a couple of things to fix it and finnaly kicked it out of recovery mode but now it had a blank screen! I then tried to restore again through iTunes useing the same iOS 4.3.3 but after that it no longer showed it was connected and working normal. I tried it multiple time in different ways that I found on google that said it would fix it. Each time I tried it I got an error code. Each time the code was one of these 3194, 20, 1600, 1601, 20. I then used iREB to put it into pwned dfu mode and tried to restore to 4.3.3 with itunes like it was a custom firmware. It sort of worked. I was no longer getting itunes errors but it still had a blank screen! I tryed to fix this using different fixes I found on Google. Still blank screen and not sure which mode its in. Last thing I have tried was iTunes restore with host file changed and selecting firmware 4.3.3. while running tinyumbrellas TSS server. Got Error code 1600 and blank screen! I dont know what else to try. Maybe I didn't do something exactly right. PLEASE HELP
