It is far from clear what you want to know?
You didn't say what happened to your phone, why it is "dead" or exactly what you mean by dead. CWM is a custom recovery but you didn't even tell us if you had it instlaled and therefore presumably have backups. Or if you are hopeful that CWM will fix your unspecified problem. And system dump is a vague term usually referring to making a backup on the command line using the dd utility.
We need a lot more information if you need help with something. Such as what happened to your phone, whether it boots to recovery or download mode, loads an ADB shell and so forth.

[Q] Somebody give me SCL23's build.prop(original)
I changed build.prop
My android phone is SCL23
AKA Galaxy S5
I am Korean but now I live in Japan for work.
So I used GalaxyS5 for KDDI AU
Some application didn't work on my phone.
Even impossible to install
So I tried to root. Then changed model and vendor from GalaxyS5 to Galaxy S4
But it didn't work for using those apps
So I copy all of texts of build.prop of GalaxyS4.
Then my phone dead.
AU's logo is the only thing I can see.
Before did that
I had do googling and find SCL23's CWM with Chinese letters.
It works well.
Factory reset? YES
Boot? NO
Can not normal boot
Odin mode
I connected phone to PC.
Fail to install USB driver.
I think it cause of phone's hardware and build.prop is not same.
I have external SDCard.
Odin work via USB
And I can go into CWM recovery mode.
So I think if I can find .zip, able to flash, of SCL23's build.prop
I can copy it into extsdcard with friend's android
Then go into CWM and flash it.
I need SCL23's build prop
And somebody make it .zip please
I don't know how to make it.
Please help me.
And thank you for read this poor English
