Title: OLED Firmware Mismatch
Post by: Slotman on July 01, 2022, 08:50:54 AM
I know this has been covered many times but I cant seem to get the process to work.

Going from a BB2 that was running 13.37 and wanting to "downgrade" to GF2 which I will be using a H9.26

I cleared and ran the H13.471 and it prompted upgrading OLED firmware and bootloader.  It then goes to the "powerfail" screen that just keeps continuing.

I than clear again and try loading H9.26 but I keep getting the OLED mismatch error.

I am at a loss.

It's been awhile but I thought you needed H9.27 (SSSG-1490) to have the OS reconfigure the deck.

I'll give that a shot and report back

You are absolutely right.  H9.27 worked like a champ.  I knew I was close and just missing something simple.
