Yes i did used the rom_user that i created.
i have aYT9216CJ and follwed the instructions from the first Post. but when i am trying to load the memory sp flash tools is seaching but finds nothing.
i tried different Windows Versions etc.
did forgot somthing ?
device manager shows the head unit as Android ADB Interface
I have an AC8227L YT9216 android car radio.
black screen after fake update
the problem is that I did not make a backup of my unit
I tried to revive my post via spflashtool
I tried with several software YT9216 1G and 2G but without success the only thing that works is that the appearance of the android logo which lights up and goes out
for information the scatter and preloader are downloaded from the xda site but the progress of the download works well
I don't know how can you guide me brother ExtremeMOD
and thank you very much
i, I have successfully installed the 1GB version of this mod. Presumably my HU is lying about 2GB RAM as SPFlashTool reports 1GB installed during the memory check. I'm slightly confused about exactly what unit I have though. Prior to the mod the system info showed mine to be 'SHA23', presumably an attempt to hide what it really is (ie YT921XXX) and CPU-Z wouldn't run on the original firmware. Vivid Launcher showed it to be a YT9216CJ so I installed the mod and radio patch. Now CPU-Z reports it as a 9216BJ.
Any advice on what it is I've actually got would be appreciated. Also, I think the answer is no, but could I downgrade to the Android 6 version of this mod? The more stable root and greater speed would be useful.
Also, despite installing Viper4Android the sound quality remains somewhat poor, but way better than the original. Is there a guide somewhere or some pre-made settings I can try as I have no idea what the options do. Finally, whilst I know enough to follow this guide I don't know anywhere near enough to understand how this unit processes audio. If I was to use the 2x RCA out plugs I have for left & right audio and connect them to a good quality external amplifier would that bypass whatever in this unit is cheap and makes the sound quality poor?
Thanks, the label on my unit says SHA23 2G + 32G. Weird, particularly as the 2GB version of the Mod didn't work but the 1GB did.
