Modify the startup screen

[Gudvi]

I successfully modified the startup screen and it looks to be running very well

How does that work? I wish I had. Even for a fee

Feel free to drop me a message if you need more details!

Hi @Gudvi,

A basic question about this: Did you do this directly on the SX920 (e.g. read out the contents of the eMMC and edit them accordingly), or did you edit a firmware update file and then reinstall the update?


Best regards,

That is so funny. Good job 👍

Reading the content of eMMC for editing is relatively difficult, as it involves editing the firmware update program.

Thanks for your feedback, @Gudvi!

If you didn't read/edit the contents of the eMMC and didn't edit the firmware update file, how did you basically proceed (where/how did you store/exchange the new startup picture)?

I'm sorry, the statement was incorrect. I achieved it by modifying the firmware update program.

Thanks, I had already suspected that you had modified the firmware update file for this purpose.

In contrast to Genos1, whose update files are available as unencrypted archives and can be opened/viewed relatively easily (e.g. using "7-zip"), Genos2 and PSR-SX firmware files (.PRG) are obviously LUKS encrypted.

Could you tell me a trick how to open/view/edit such LUKS archive files? How can you find out the LUKS passphrase?

Yes, both SX and Genos2 use LUKS1 encryption, but unfortunately, we cannot make the key public

Thank you, so we have to accept this.
