I am having CM 10.1 KonstaT and CWM Recovery version 220.127.116.11. now. I installed recovery 1,5 years ago by Recovery Manager. I want update recovery, because I want install CM 10.2 or CM 11. I don't want do it through TPT. I found file recovery-clockwork-18.104.22.168-blade-gen2-update_signed.zip and I can install this zip by install from sd card in currently recovery? Must I do it another way? I have ZTE Blade Red Bull Mobile One version [GEN2] Sorry for my bad English.
