SP Flash tool isn't that big. It's only 10 Mb or less.

 

[cheesmountain]

Sorry, misexpressed. If I connect the radio to the PC and start SPFlashtool then it only charges up to 4%.

I tried at least 10 versions of the tool, always different memory dump size.

And at 730mb it doesn't go any further.

Hello
Can I install it on my head unit? If not, do you have some alternative for some good rom?

This is likely an issue with your USB connection. Please check this post for help

It was on the Win 11 PC where it didn't work.
Windows 10 with no problems

That is correct. This won't work on Win11.

In the end I overlooked it, how can I play the firmware from the download on my radio?

I f you have Windows 10 or earlier versions, simply follow the guide in the first post. The firmware file includes individual guides for every part of the installation. Make sure however that you System is compatible and don't skip the backup.

This message comes when loading the firmware from the package.

Your head unit is incompatible

Your real version of Android is Android 8 API27. This mod will not work on your head unit unless you know how to downgrade to Android 6 API 23. Try our Android 8 SuperMOD instead. The link is in our forum signature.

A side-note: it is highly likely that your head unit doesn't have an onboard audio processing chip, which means this firmware will have zero effect on the sound quality

 

[cheesmountain]

Thank you very much, then I will deal with the Android 8 version.
I soldered an audio chip.

hey man, thanks for the video tutorial on how to do a backup.
i managed to restore my ****ty yt9213a that kept rebooting (boot loop) because i toggled "video output" in settings.
i have an yt9213a with 2GB RAM and 32GB.
i managed to install spf flash tool, do a backup, get preloader, scatter and other files and then felt cocky and did a mixed flash with your system.img fo yt9213aj (i thought it would be snappier) and twrp 1GB as recovery.img and boom: now i have a fast ROOTED unit. no more endless tapping the maximize toggle.
many thanks!

i would try to upgrade to 8.1 but i dont know what to flash and what not.
am i correct thinking that for that to work i have to flash all the files in an 8.1 update zip (from file.xygala.com) except preloader and recovery.img?
can i flash from twrp?

Hello propably i have radio yt2913aj. I don't check version before and few days ago is freeze at android loading. Reset and take out from battery don't fix it. I decided to flash it but find few versions what don't starting with this radio. Next i find one rooted and it start, it's show sucessfull. When i put radio to car nothing happen. I take it back to home and try flash it one more time but at home nothing happen too. I think i brick this radio, is any chance to repair it back?
