Root [International] GS3 root gone wrong. Black Screen of Death

[Edge23]

Hi All,
I have tried to root my Galaxy S3 using odin, somewhere in the process something went wrong and now, when I turn on the phone I hear the entry sound but the screen is completely blank. I wiped the data, cleared cache tried installing another rom using odin (computer sees the phone, odin starts process then I get this
<ID:0/007> Removed!!
<ID:0/006> Added!!
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..

I tried to put the new rom on a microsd and install new rom from there.It says "Successfully applied multi-CSC"" but the problem continues. Any &#304;deas?

Hi and welcome to the forums,Edge23!

I'm guessing you have the Verizon S3 and running jellybean.

I have not rooted my Verizon GS3 running jellybean yet so I'm going to move this to the all things root section for your device. There is a lot of people who can possibly help you.

Found this droid life article with the new root method for JB. It has a link to the xda instructions and a video. If you are on JB and used a method made for an ICS VZW S3, then maybe that's what went wrong with your process.
But like I said I haven't rooted my S3 yet so I'm not entirely positive that is the issue.

Per the OP, he has the I9300. I moved it for organizational purposes and just in case he has other issues.
