I've managed to take the GIT of android 4.2 and get it to compile with the crespo device tree from the 4.1.2 GIT repo with some minor modifications.
I currently have a GT9020A (fido canada network) and I'm currently running android 4.2 on it with my custom kernel.
New Source tree added. Not my latest on the crespo source but it includes the crespo4g and also I linked my kernel image in the device tree
