soft bricked phone with mobile odin 4.20

Hey gang,

I just soft-bricked my phone using mobile odin 4.20. I was trying to flash lollipop 5.0 .tar file.

I *can* access download mode but no recovery mode.

I cannot odin my phone yet because my office computers are "locked" for "outside applications."

I do have a usb OTG (on the go) cable and odin copied to a thumb drive.

Any ideas are welcome, except wise guy remarks.

TIA - thanks in advance.
