Hi,

My phone Galaxy ace s5830i is locked due to an excessive number of invalid patterns.

I want to install “Lockscreen security Bypass.zip” to unlock it, which requies “cwm installed”. Can I install ClockworkMod recovery for Galaxy ace s5830i before rooting the phone? Will cwm recovery delete all data of phone??
