Hope someone can help, last night I got a refurbished 2g 8gb iphone from the apple store, used the guide from modmyi (redsnow)and it had an error after the download I tried to restore on itunes and now it gives me error 23, can anyone help with this, I appreciate it, thanks
Put in dfu mode and try again. May want to try recreating or downloading custom firmware too.
Also, you may want to try on a different computer if possible, Read somewhere that you may have some corrupt files in backup, and its easier to just use a different computer rather than trying to chase down the files.
