I tried both CMW and TWRP. When entering recovery mode with CMW my phone is stuck on bootloop, when trying with TWRP all my phone does is full wipe. I used KDZ twice to flash firmware V20A, I'm using newest Impactor to root my device, and I used Rom Manager and Goo Manager to flash CMW and TWRP. Both on clear system of course. Now I'm stuck, and I'm looking for advice how to install Android 4.4.2 on my phone.
Nevermind. Solved. I used "UNLOCK L5 BY HUGO GABRIEL" app to install CMW.
