(Sorry for my bad english)

Hello guys,

I've just installed a cwm for my phone, and after a reboot it stucks on samsung logo, with blackscreen while charging.

I can't access to recovery and download mode, I can only access to ramdump mode.

I've tried using a jig to force accessing to download mode but nothing happens, it stays on samsung logo.

Can ramdump mode help me to repair my phone ?
