flashing with PKD-1 dongles

Hey guys,

I am using Wintesla 6.43 from the Nokia Partners Website. I am trying to flash a lot of 7160s to the v1.07 software. I keep getting "Failed to send data to phone: reason - general error" window. When I hit OK, it says "MTI Fail: MTI, Timeout" error window.
My question is, will a PKD-1 let me flash phones with wintesla ? or do i need to use a FLS-2D dongle?
THe other question is about Phoenix - can I use Phoenix with the older Nokia phones using a different cable attached to the FLS-4 or was it specifically for the 3300s and up ? For some reason I have had nothing but problems with Trying to install Phoenix and Wintesla on the same Windows 2K partition on my laptop so I had to split my hard drive into 2 partitions to use both programs on the same PC. I'd appreciate any help. Thanks
