Surfans F20 Screen Flipped After Rockbox Install

[vampire_duchess]

Hello Rockbox Community,

I recently installed Rockbox on my Surfans F20, which came with firmware version 3.0. I followed the installation instructions provided on the Rockbox wiki:

https://www.rockbox.org/wiki/AIGOErosQK#Native_Port_Installation_40update_files_45_the_preferred_way_41

I downloaded the "Surfans F20 V3.0 - V3.3" files as instructed, along with the latest daily Rockbox build.

After booting into Rockbox, I've encountered a significant issue: the screen is flipped (inverted).

I've seen some older posts mentioning this screen flipping problem.

• Is this issue currently being addressed or is it a known, ongoing problem?
• If a fix isn't available yet, is there a reliable method to revert back to the original Surfans firmware 3.0?
• If a revert is not possible, what are my options?

I'm concerned about the functionality of my device and would greatly appreciate any assistance. HELP!

Thank you for your time and expertise.

I replied to your post in the overall Eros Q thread, but I suppose you must not have seen it - It is our understanding that Surfans F20 V3.0 units have the new screen, but it's possible that that isn't correct. Try using the hardware 1 and 2 bootloader installation file: https://download.rockbox.org/bootloader/aigo/native/erosqnative-hw1hw2-erosq.upt
