How To Downgrade Your Minecraft! (2 minutes Max)
I already posted this but loads of people keep posting their getting the error so meh....
This fixes the error - something something missing byte or invalid byte. well it something like that. It just means your using a newer version of the game when the server your using to connect to is using the older one.
Do What I say *******!
The Downloads
I've scanned all these files and used them all myself no problems but it doesn't hurt to scan them yourselves just in case.
The Client - You'll be using this to run Minecraft, once you've downgraded don't run the original Minecraft client because it will auto update. Place this on your desktop or where ever you want just remember to run this instead of the original.
Extract the contents of theses and leave them where you can easily get at them...
Version File - We'll be using this to trick the new client into thinking there is an update - even though there is it need this file for some reason.
The Old Version Of Minecraft - This contains the old Bin folder from before the update.
Step one - Find the .minecraft Folder
First you going to have to go to your .minecraft folder.
To do this open you run (to do this go to accessories and run should be there, or search it) Type in %appdata% enter, the .minecraft folder will be in there open it up.
Step Two - Editing The Folder.
Now You're in this folder I want you to rename the bin folder, what ever you like but it seems that "bin - update" would be the best.
You now have to copy the bin folder we downloaded earlier into this file. simple drag and drop, copy and paste what ever you like :O
Go into the bin you just put there and put the version file in their we also downloaded.
B00M You're DONE! :D
Step Three - Lets Play Some Minecraft W00T
Open up the client we downloaded, login and continue without the update.
Remember to use this client every time you want to play minecraft or it will auto update, which you dont want to do until the server you play on has been updated.
SIMPLES
So that's it, any problems just ask!
Ohhh and thanks go to Josh he's the one who found the client we need to use.
