"Embedded flashloader not responds" problem

Greetings guys, newcomer here. :a013

I have this s500i which I flashed to w850i. It flashed ok but got my network got locked. Ok, got the SIMLockPatchGen 2.1 and generated a .vpk file and loaded it in SE Tool 2 Lite. Checked the "quick access" box and clicked on "Write SCRIPT".

Then nothing happens! Sometimes the cellphone even starts up with the USB Mass Storage screen, causing the flash bootloader not to load and I get the ""Embedded flashloader not responds"" message. Why is that if I can flash my firmware with SE 2 Tool Lite and XS++? What am I doing wrong?

Sorry if this is a newbie question or has been asked a thousand times... but I am kinda in a hurry to get it working again. Hope you guys understand.

Thanks!

follow the tutorial How to apply the generated patches to DB2020 CID52 phones Thread: Remove SIM-lock patch generator

may be you ran out of battery

as far i know it need to be applied bypass DB2020 security method for making able to use the quick access method.which was not done by miretank so the quick access method wasn't work for him.
