good intentions. but....
L7 and L9 have diferent CPU. L7 is a Qualcomm MSM7227A Snapdragon and the L9 is a TextasInstruments OMAP4433,
L7 does not implement a u-loader and a x-loader , it implement an unencripted
aboot loader, besides L9 have encripted
x and u loaders.
The boot.img and the recovery.img of the L7 can be "patched" to bypass the bootloader because the aboot is un-encripted, for this reason this can be done with loki tool
but L9 is very very difficult, i mean near of impossible to patch because the algorith of encritation have a very large and very very secret key (CertPK), only knowed for LG.
