K790a - blinking white screen.

[Jazz]

Hello.

A customer brought in a K790a which was not booting past the opening logo.

When I connected to Cruiser it told me" It is strongly recommended to upgrade EROM!"

Which I did, and then upgraded to CID-52 and flashed it....however, now when you try to turn on (or charge it), the screen flashes with a white screen on and off.

Just wondering if there are other suggestions after this?

Thanks in advance.

PS - here is log:
