The Galaxy Note recently saw the release of an unofficial Ice Cream Sandwich (ICS) Android 4.0.3 firmware leak, that many welcomed with open arms as they got a chance to try ICS on the Note, and also paved the way for developers to start building custom ROMs based on ICS. However, it seems some people are running into issues when they try to install custom ROMs from clockworkmod (CWM) recovery when on the ICS firmware.

Here are some of the problems that people are facing:

  • Modem flashing takes forever
  • Extracting system is done in like 1 sec (while flashing a ROM from CWM)
  • Bootloops after flashing custom ROMs

This guide here will help you flash a custom ROM successfully from CWM recovery on ICS, so read on to find out how. Do note that this method is not a fail-proof method, so it might not always work.
