It was showing set partition (above id com block)
for almost 8mins so I thought something is wrong and plugged out the cable and restarted it went to the BSOD logo and is now only entering download mode.....
I am really sorry as I know I shouldn't have interrupted the flashing . I just freaked cause nothing was happening.
After I removed the cable the log in odin was.....
<ID:0/009>
<ID:0/009> Re-Partition operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
<ID:0/009> Removed!!
Please help immediately
And with clear instructions so I do not make any mistake and restore the phone
