I have two questions..

1. Is it neccessary to flash with Custom emmc i already have more than 900mb for application installation.

2. And if its really neccessary, can I backup with backup menu on stock EMMC and restore it when i flash it with custom emmc (of 5gb), and get back to normal. (please tell me if you have done this or know it would be successful)

P.s I'm asking this because i installed nitdroid about 10 times, it was successful all the times but then I restarted the mobile to get maemo or I worked for more than 5 minutes in nitdroid it gets stucked and had to force restart and I finally have to reflash, please help me as this is my primary phone, I like to use nitdroid (for games) and maemo (for other functions) together.

Any help will be appreciated.,..
