Use the programmer that supporting secured flash read/write. After reading flash edit address $FF0F data from FF to FE and write back.

If the chip is still secured your programmer organised the flash in different way, upload the read flash.

Hi
What programmer would you say read secured flash? What fault is upa giving? Isn't the secured bytes obtained from the mask?

Aim to me ?
What programmer would you say read secured flash? > Any programmer that support HC12 secured ex. Xprog (supported version)

What fault is upa giving? > maybe not to me, but all old UPA's not supporting secured HC12

Isn't the secured bytes obtained from the mask? > Sounds like you mixed up the security mechanism of HC12 and HC08
