Help reading smart sam.

[Galee]

Hi all I wonder if some kind member can assist with where i'm going wrong trying to read and write this smart sam unit please from a smart roadster 2004 I am having trouble reading correctly smart sam with upa and vvdi prog. Upa read correct but the file size is incorrect. I have used connections posted by member Pipnina(Thank you) on here and have virgin flash ect but when I try reading flash I only get 64kb file I know should be 2048kb. I have lifted pin and had to put link wire in due to it being knocked and lifting a pad on the board. Btw genuine upa. Here are attached dumps

I have tried with these connections still no joy this is with upa

Anyone got any other ideas or connections how I can read and write this sam with either upa orig or xprog clone or vvdi prog?

Hello , you need to use 3.3V in UPA , this kind of MCU use low voltage for working .I think your UPA gives bad contact on VCC , corect ???.Also check your wiring because connection from forum MUST work in circuit .
