Using Dual Recovery for Xperia Rollipop - Bad manner but no choice

In XDA, we can get Root with Xperia's 5.02 roms - but cannot use Recovery after flashing it.

Actually, very bad manner, but with it, it seems we can use Recovery in Rollipop.. 

If you would like to use Recovery..

Flash Kernel and etc from Sony's official 4.4.4 TFT. ( refer this link)

After boot, it takes long time but we can enter the recovery by clicking volumn down button.

After some manipulation, turn off device.

Then, flash Kernel and etc from Sony's official 5.0.2 TFT.

Then, your device boot normally.

Not good method but we do not have any choise.
