I know the thread title is for Bolero, but I have Swing radio (Physical buttons) in a 2020 Scala.
Is a f/w update possible with this?
Currently...
SW Train MEN3_EU_SK370_P9305P
MU SW 0463
I have MEN3_EU_SK370_P2345L and MEN3_EU_SK370_P3355L_1800
I have puzzled folders on USBC - USBA adapter but radio refuses to use the above.

SWMBO and I are in the Pixel/Samsung camp so ongoing connectivity issues.

Thanks in advance

Version should match if its same SK370 Try different usb drive or buy cheap usb c to usb a otg adapter. Thats how i did mine.

Apologies, I should have been clearer...

My SWING (Physical button) headset is currently running... SW Train MEN3_EU_SK370_P9305P, MU SW 0463

I have I have MEN3_EU_SK370_P2345L and MEN3_EU_SK370_P3355L_1800 downloaded and on USB.

(From mib-helper and mibsolution)
These are unzipped in their respective folders on the USB.

The car seems to be able to read the folders on the USB, but it does not do any update.

A stepped upgrade may be required.
If I am on P9305P - Is P2345L or P3355L a downgrade?

Go with P2345L and then to P3355L

P3355L is the latest v (1800) maybe there is newer. But on mibsolution that is latest one. And there is no newer one available on the internet afaik.

You can put both unzipped folder inside the root of the usb drive. And then follow the instructions: https://youtu.be/o0RIdpKQ2b8?is=Yn6CeyB0U3i_uPQ1

Picked this up from russian forums, they seems to know alot better about this stuff:

– MEN3_EU_SK370_P0113P_0469;
– MEN3_EU_SK370_P2131P_0741;
– MEN3_EU_SK370_P2135P_0742;
– MEN3_EU_SK370_P0314L_1233;
– MEN3_EU_SK370_P0393L_1310;
– MEN3_EU_SK370_P1185L_1760;
– MEN3_EU_SK370_P2345L_1790;
– MEN3_EU_SK370_P3225L_1798;
— MEN3_U_SK370_P3355L_1800.

Based on the metadata of firmware, the following transitions are permissible:
0464 => 0469 => 0741/0742 => 1233/1310/1760/1790/1798/1800

I really appreciate the update and the legwork on this!

I am not going to proceed as there are SW version limits and a risk of bricking unless specific versions are used. Availability of versions (example SW0469) is limited, so main dealer looks like the best approach.

Thank you!

Yes, its best to not mess if there is limit. Youre welcome.

In my case i had this path:

But thats different story
