Could someone point me in the right direction on Kropki #39 from the WPF GP Round 2? I'm not an expert on this puzzle type, so I'm sure I'm missing some elementary logic here, but I've gotten absolutely nowhere on this.

Encountered this frustratingly irritating Linesweeper variant that plays around with the rules in the Loop PR round.I couldn't complete it during the test (and even later), discarded it in a corner and totally forgot about it until I saw it creeping up in the LMI fun contest again.So I decided to clear up this puzzle once and for all .I continued until this point unsure of whether it is right or wrong.Could someone post the steps until the end?

What is the logic for solving this particular puzzle other than the obvious ones at the lower right and top left and the not so apparent top right ?

Firstly, your bottom left part is wrong. I don't know how you got that.
These are starting steps, which i followed. I hope it helps.

I thought the top right counts as obvious, since there is no other way to satisfy the double 4. Swaroop has the intended start.
