You need ETL705B16 programmer .

I think that UPA is eraseing that MCU when you read it.

No,
UPA will not erase that MCU, but you still need ETL....

Lift Vddsyn pin
Replace the crystal with 8MHz one

Upa doesnt erase what you read.
The only thing you can not do is read after write the new file.
You can read it lifting just one pin but the better choice for upa and to finish with all upa reading erros is to buy the adapters from www.ecuvonix.com (http://www.ecuvonix.com)
I am here to help my friend not to talk about others work.
