Default [Q] what tools the rom build using?

I'm a newbie. I hope build some roms for my Ascend P6.

I using the kitchen tools at github.com/dsixda/Android-Kitchen

But, this tool is too old.

1. When I using it to unpack the P6's UPDATE.APP, it cloud not working.
I find a newer script, replace the split_updata.pl .

2. At last, I pack the rom to *.zip, send it to my phone, when I install it at TWRP recovery, TWRP can not read the zip. The error message is: "Error executing updater binary in zip."
My TWRP version is 2.6.3.3.


Hi, guys, what tools you using for build roms for Ascend P6? Tell me?
