I have a Samsung Charge running 2.3.6 I ran thru the ODIN and that went thru fine, but when i try to apply the root.zip file i get a "signature verification failed". One thing i want to point out is that in order to apply the root file i have to press the home button. The button on the side (camera button) does not work. i see a load window flash and then the error. This is quite frustrating and I have poured thru threats and I can't find anything helpful. Please help!!! this is real frustrating. Thank you in advance.
