& hope it will work post custom kernel flasing (speedmod)??? I have the jig which i used on s2 & it is not working after i flashed the speedmod kernel.
So can i follow this procedure to reset the counter & remove the y.triangle??
It will work., I was on the custom latest firmwares (rom, kernel) when I flashed to remove triangle.
I consider myself an advanced user. But it easy to become confused.
Because it's not only
"screen" will not work!...
Also will not work sound, and lights., so even I got confused, the first impression is your phone is "dead". No restarting sound, no lights, nothing working ...
I even imagined in the mind, in what mode the phone is now, but it still does not help

So long story short I was able to connect my phone to Odin after 13 times I tried.
Regards.
