Hi guys,

I recently got myself a samsung galaxy s3 gt-I9300 model.
Im trying to flash a custom rom. (mike1986's android revolution 7.0.0 HD).

But whenever i flash, or a superwipe or any other rom which i try to flash,
I get a E:/ signature verification failed.

Any help please? :(

UPDATE: SOLVED

Using clockworkmod recovery??
Stock recovery only allows .zip's signed by Samsung.

Sent from my GT-I9300 using xda app-developers app

As above....are you rooted? If not then use c.f. root, find it in original android development

Sorry for the late reply,
No sir, im not. I'm trying to root it using mike1986 thread. Thanks for the tip. I'm now trying using chainfire's method.

Update :

Installed samsung kies, updated all firmwares and device drivers.
Opened up Odin, added in the .tar file and connected my device "ADDED"

Completed the process. Had SuperSU and CWM in my device!
