How do I Install a custom ROM/recovery on a Galaxy Note 2? I was trying to install CyanogenMod 12 Lollipop ROM on my Note 2. When I restart my phone in recovery mode, its giving me this screen:



After this I select the option "wipe data/factory reset" and then choose option "apply update from external storage" and when try to install, it gives me this error


  failed to verify whole-file signature. signature verification failed




Please help me to solve this problem.
You are using the stock recovery, which only allows files signed by Samsung to be flashed. Flash a new recovery via Odin, such as CWM, TWRP or Philz.
