Custom recovery, can it brick my phone?
Well first i will answer your question. If you want to use a recovery made for a complete Another model for your phone, yes it will brick your phone. Even though another model is very similar to your phone's model, it's not identical! There will always be some differences internally. For such cases you have to port the recovery. Before going for porting, Go to xda forums I'm sure there you will find a recovery for your model. But if you don't find it there, you need to port one from different model to your own.

For recovery porting is not easy and very risky I'll advise you to take help of someone who is well experienced in this. And proceed on your own risk.
Another part i would like to add is flashing recovery and rooting a phone are completely different concepts. Please read thoroughly on xda forums before proceeding.
