It did not work so I started the whole process from the begining.

I am using April 22 version of duokan, btw

When I come to step 4 as outlined by you, I found that in DE_Update in k3 there is a subfolder called DK_System.

Am I supposed to move this subfolder to DK_System on kindle and then delete or remove the bin folder as contained in it?

Or, am I supposed to move the contents of this DK_System subfolder? That poses a problem because it contains a subfolder called system and we already have subfolder system in DK_System on Kindle.

When I look at your code, I see config.ini file. I see this file in DK_System within the update/ks subfolder. Can you help me overcome this confusion which may be caused by different versions of duokan or by my sheer stupidity, either.

Thanks.
