Flash LG PK5 DEMO - CH431A ERROR - verification error on address 00000000

[kyrios]

Hello!

I apoligize for my English. I need some help.

I have an LG PK5 in demo version and trying to repair it, I found the original firmware in this forum to flash speaker to the original version.
Without having any idea about these things, I give thanks this forum and other tutorials, I bought a CH431A programmer and I have tried to do all the steps but after reading the new firmware, in the "verification" step I get this error: verification error on address 00000000
Could someone help me to solve it, please?

Thank you so much

I'm having the same problem with my PL5 and PL7 (newer version.) I'm also still learning and could use assistance.
