Download - ROM manager - then select flash zip from sd and select options like this pic
Its not working with rom manager. I don't know why but rom manager does not reboot to recovery. I did it the long way installed your rom but the recovery is still corrupted. I installed this way wit EU or US kernel, with and without the radio unlocker the your rom and gaps. After the bootstrap the recovery work ok. Then when fleshing rom ends the recovery is not working right.
Process:
1) Boot to Recovery & Wipe Data (R+M+Power)
2) Boot to Bootloader (Up+Down+Power) & SBF to 2.26 (Using RSD Lite & SBF file) - Usually I have to copy SBF File to root of Hard Drive & name it 2026.sbf or it may fail (ymmv)
3) Skip Activation (Bypass activation on your Android device | Android Central)
4) Settings->Applications, Set Unknown Sources and USB Debugging (in development)
5) Root
6) Install Bootstrap apk, open, press 'bootstrap recover'. then 'reboot recovery' to boot to recovery mode.
7) While in recovery mode, and without rebooting at all:
...a) Wipe Data
...b) Install Radio Unlock
...c) Install Kernel
...d) ROM+ Gapps
