Yo u say you added a New 206e, there is not such thing as New. Probably 20 years old or more.

Sometime times you have to either walk away or upgrade. Plenity of use Partner processors R 7 or R 8 and Refurbed 3x 8. Get rid of the 206 Mods.

You have been at this for weeks. It's must be costing the end use a fortune for this. Unless for work for free.
