Above are 2 android 7.1 & 8.1 example. Below is Android 9 example.
This is for those who have a ( 8227l ) android stereo and are looking for the update file zip. Also the mcu in the about phone menu should begin with ts . I have 5 files from jby tech, they are the Amazon seller of my hizpo android 8.1 stereo unit. From lots of research and emails to the company, i found that these Android stereos come in many brand names but run the same 8227l system. Another company with the same unit is joying but the device name is different along with the entire UI. Please do be sure you have a 8227l unit before proceeding. Other updates for other brands can be found on google and xda forum. I will try to remember to put link for xda forum. Below I have listed 2 groups of files. One is for touch screen only android stereo and the other is for touch screen with volume knob. Please choose according to your type of stereo. And follow the steps below exactly.
1. Download proper zip for your device.
2. Extract the 2 files from within the zip folder.
3. Copy & paste the ( .bin ) & other file on to a blank sd card or usb flash drive. Make sure these are the only 2 files on the sd card or flash drive.
4. With stereo unit powered off insert the sd card or usb flash drive and power on stereo. (Note some units will recognize the file immediately during boot, and others will prompt you after loading main screen. If unit does not recognize it, power off for 40sec and when u power on tap the screen in middle repeatedly with finger until the word "detected" shows in green. If it gives a message in red saying failed please check you have good download copy and have followed the instructions exactly. Will answer questions as i am able to.
All links to files and sites mentioned must be copy pasted. Im not able to attach external link yet.
