No cwm or download mode- S3 stuck on Boot screen

Hey guys, I hope someone has an idea:crying:.
I was on CM10 latest preview, updated rom manager and tried to reboot into cwm recovery. Now the phone is stuck on Galaxy S3 boot screen and I cannot enter download mode or recovery mode. When I put in the battery the phone directly boots till the Samsung Galaxy S3 can be read. Additionally it is no longer recognised by my PC. I don´t know if usb debugging was enabled before this nightmare started. I installed the usb drivers again but Odin and Kies doesn´t recognised the device.
Does anyone has an idea? Should I buy a JIG?
I would kiss your asses if you could help me! Thanks.

[Q] Samsung Galaxy boot loop

(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 ?
Looks like you flash a firmware for the wrong model? Without download mode you are stuck, sorry. Never heard of ramdump mode.
