Signature error while trying to flash a ROM
Hi, I'm newbie in the Android World and I have two questions.
I have been multiple days reading this forums a I'm very impressioned.
1.- I used Heimdall to install Clock Word Mod Recovery 6.0.23 on my new Galaxy Tab 2 7.0 3110 PHE, all perfect, but when I try flashing with CWM a custom firmware it says IS NOT SIGNED. I'm trying to flash kwbr_Espresso_Full_3.0.zip downloaded from the forum of Android development and not modified in any way. Is there a solution?
2.- Should I be able to modify a ROM in order to add my own scripts, and then flash it?
Thanks in advance....
