[Q] Update to 4.2.2 failed. Phone not booting!!!

Hi all,

Last night, i rooted by N7000 through PhilZ-cwm6-DDLSC-ODD-5.08.5-signed and was successful in doing that.

Later i wanted to update my device to 4.2.2. So i downloaded cm-10.1-20130727-NIGHTLY-n7000.zip file and kept in my external SD card.

Then in recovery mode,i wipe the factory data. There was option wipe data or wipe to install new ROM. I selected the latter one. Wipe for installing new om was successful. Then i went to update zip.file option. But since the file was in external sd card, it was not detected and i was not able to select the file. Then i rebooted the phone but only 'Samsung galaxy N7000' screen was coming and nothing was happening.

I rebooted my phone many times but same screen was coming. Then in morning i went in advance options. I selected Recovery Bootloader. Downloading screen was coming and nothing was happening. Then i switched my off and trying to start in recovery mode but its not starting.

I thin i have no checked USB debugging.

Kindly help soon as i am helpless without phone. Your early response will be highly appreciated.
