I am concerned what the effect would be downloading software from some of these sites. Edit, why I don't think this is a dupe: I don't think that is a duplicate because there the answer to that general question is that it is no longer possible. But this specific case does appear to be possible in light of recent developments.
Plus one answer mentions many devices but not the iPad 2. Finally, that same answer has SHSH as a pre-requisite , my question excludes that. Apple is currently signing iOS 6. AltDeploy just signs an app with a 7 day certificate based on an iTunes account and installs it to your device.
AltServer does the same, but then runs a server on your computer so your jailbroken device connects to your computer via wifi, and requests a new version before the 7 days run out. Both of them install a rather dodgy plugin. I then used AltDeploy to sign the Phoenix app. This also failed, but this time I got an error that I could search for a bad app display name. It seems the Phoenix app uses extended characters in the app name to join the o and e characters together.
Anyway, this issue suggested changing the Phoenix5. Then the signing worked, and I had the Phoenix jailbreak app on my iPad! I followed the instructions to activate it, then kickstart it, then opening Cydia and installing ssh.
After I did that, I had a factory-reset device running iOS 6. It seems to be stock iOS, signed by Apple with no jailbreak although I believe there are iOS 6 jailbreaks that could be installed.
But I want it nice and clean, for my museum Check out that retro skeuomorph ic design! IPSW found at given path Step 6: Locate the ProductVersion key and change its value to 6. Step 7: You are now going to need to find the corresponding build number for the firmware. For example, the build number for iOS 8. So if you are going to want to downgrade to 8. The build number for iOS 6. Step 8: Now you need to reboot your device. You will then notice that iOS 8.
Go through the update installation as you normally would with any OTA update. Step Once done, you can untether-jailbreak your iOS 8.
