Why don't you put up instructions on how to roll back if you are worried about it?

People posted instructions on how to upgrade for people willing to take the risk. They aren't servants. They are taking their own time to post these things up, saying what they "should" do is quite rude in my opinion.

That being said, I'm also pretty sure that people did post how to make a backup before you applied the upgrade just in case. I know I did right here:

Where's that come from?

 

well non rooted users were able to do this. I think they shouldnt of. We rooters can nandroid and stuff so its not bad for us. As far as the links being dead, i highly doubt it. Check here,xda,modaco, google it, im sure its out there. As for if its the official version? No one knows, but us rooters will be able to easily convert. The question is, for the people that manually updated, will they get an OTA if that wasnt the official version since they are running 2.2 already?

 

jesus, if you don't want to root your phone, or unlock the bootloader you have no business installing anything other than apps.

I do feel that some people (this forum and other tech bloggers) have been a little irresponsible in perhaps, posting insufficient information with their "hey guys, grab this froyo update quick", without actually pointing out the potential downsides........at least I and others, were a little more specific.

But then again, you can say the same for the people who were not rooted and forced the update anyway (but that is not to say that I do not feel sorry for you now if you are having issues with 2.2). Only if you are rooted, can you go backwards.

Bit of a bloody mess

 

ya it does go for the OTA update, unless it comes down to your phone without you doing anything you have no business manually installing unless you know what you're doing.
Not trying to be a dick, I was just reading some other post somewhere else about the same thing, got a little carried away. My comments were uncalled for, I apologize.
It's easy to learn everything you need to know about all this stuff. All it takes is some time and patience.

 

worse comes to worse, youll have to manually update the official froyo if its any different or exists

 

My issue isn't whether you want to root, or whether you installed the update. Its the fact that you said it was the people who posted the update tutorials responsibility to post how to revert back. That is just wrong. They did something to help the community, anything that happens while you mess with your phone is purely YOUR responsibility. You have to be careful and understand the risks before you do anything. The fact that you are almost demanding that they explain how to revert back rather than ask for help just kinda irked me.
