I have an xtrons (or rebranded alps) unit. It's an 8227l. Is this mod compatible?

That's a great question. I want to know that too.
Are there actually any real 2GB RAM devices?

I bought a new head unit recently and it was suppose to be a 9217B but in fact the one that arrived is a 2gb ram and 32gb rom 9212B. I was wondering if one of the modded roms were compatible. I saw one earlier comment one user saying he had this unit and the equalizer didn't work because probably didn't have one audio chip. My unit actually have that chip (csc2313s dka6v) and the equalizer works but I have a problem that the audio in the lowest setting is to high and the fact that the original rom sometimes it's slow and some glitches happen. In the attachment i send some pictures of my unit. Thank you for your time and effort.

Now I'm not with the unit connected but tomorrow I can send pictures of rom it self. The rom says it is a 9.1 car edition and in the CPU-Z actually says it's api28.

 

[diogo99almeida]

Here is the pictures I took from the head unit today. It's a bit strange, the kernel in the device appears as version 4.14 but in the cpu-z appears as 3.18 with api level 28. Some of the instabilities are from of the wi-fi signal going down all the time. I'm thinking of installing a wifi antenna. I was wondering if for the bluetooth the same antenna can be used, or should I use another one?

WELCOME!

I'm sorry about the bad English speech, I'm writing with a translator...

I wonder how this package would work on my device?

Currently android 11 runs, but unfortunately the radio does not work and reacts very slowly. (Belated)

Thank you for your help.

Okay I messed up. I tried to do a flash update and now I’ve got the black screen. Nope, no backup file… I know it’s not bricked because Bluetooth still connects and plays audio. Also I get a screen flicker when the reverse camera tried to kick on. Really need some help. I took these photo before hand. Am I SOL? Thanks In advance.

Hi all,

If you want to greatly improve the way your head unit works, sounds and looks like - you've come to the right place!

Why install this?
With this package you will greatly improve:

• Stability
• Speed
• User Interface
• Sound tweaking options
• Customization options

View attachment 5383193

• ON PHYSICAL BUTTONS: this software has only been tested on head units with no physical buttons (like volume) | Before making any changes, access the CAR SETTINGS -> FACTORY SETTINGS -> ENCODER SETTINGS on your head unit and take a screenshot of the current settings (see example below). After installing the package, go back to these settings and adjust them if needed. If that doesn't help and if you can't successfully re-calibrate the buttons after installing the firmware, restore your backup

Disclaimer
I do not create the software itself but rather use research and put together different mods and hacks into one package that includes very user-friendly step-by-step instructions on how to install it all. You will find the links to original posts in the instructions pdf's if credit is due. The software might include smaller changes made by me and has been fully tested in real units.

This guide works on the following 1Gb RAM and 2 Gb RAM units with fake Android 10 and Android 11 installed:

- YT9216BF | YT9216CFJ | YT9216BJ | YT9216BFJ | YT9216CJ

!! TAKE A PICTURE OF YOUR SYSTEM INFO AND KERNEL VERSION BEFORE DOING ANYTHING TO YOUR HEAD UNIT !!​

The zip file package contains:

• Modified firmware - courtesy of Stranger21UFA @ 4PDA (link to the original post)
• TWRP (separate folders for 1GB and 2GB RAM units)
• Root via Magisk
• Viper4Android
• Car Launcher
• Boot Animation
• SEPARATE INSTRUCTIONS ARE INCLUDED IN EVERY FOLDER

​

>>>> ALWAYS BACKUP YOUR UNIT BEFORE MAKING ANY CHANGES TO IT <<<<​

​

!! IMPORTANT !!​

This is a fairly advanced installation process and will require you to follow the individual guides included in the software package - to the letter. Failing to do so, will (in "best" case) result in a slow and buggy head unit and in the worse case - brick it altogether.​
