You can install this ROM as a 2nd ROM using blackhawk's NEXT dual boot solution. Read the Dual Boot FAQ carefully.
Better I write it here, for T310 and T311 only for now.
Prerequisites:
a) Flash latest blackhawk's NEXT kernel
b) Flash latest PhilZ Touch recovery
c) Atleast 90% battery left.
d) 4 GB free on internal SD, 2 GB claimed for system image, 2 GB spare for data (dynamic claimed, depend on 2nd ROM data size)
e) Some spare time
1) Setup this ROM as secondary:-
i) Reboot into recovery
ii) Flash blackhawk's NEXT tool, create system.img for stock/stock based ROM and then close it
iii) Reboot into secondary recovery with red on screen navigation buttons, AROMA based boot menu will help you
iv) Flash this ROM as 2nd ROM. No need zip modification, it's a magic
v) Flash blackhawk's NEXT kernel again
To be honest, I never tried this ROM myself as a 2nd ROM but my own stock based and CM. Follow above guide at your own risk! I hope
@DutchDanny can confirm this method for us :good:
