I tryed to install roms from xy site and as i expected scatter file gave me error... Someone with advice for this issue?
Thanks for your response! I am a little relieved that i'm not the only one with such problem.@lagakappa96 i have the same unit yt9216b 2/32 and at this moment im looking for the same. Unfortunately im now with firmware for 9250 and my touch screen and sensor keys dont work. Only with plugged mouse i can use the device. Tomorrow i will try with one of these and with the original preloader file from site : http://file.xygala.com/?dir=uploads/XY公版/9216/9216B/Android9.1/中文/横屏/1024x600/UI1_v6.5
To log there you can use username xyauto and password 123456
Im attaching screenshots with what i gave atm.
Thank you,
so if I understand,
white / yellow = volume -
white / green = volume +
No, it's the other way around - white and green are for reducing the volume, and white and yellow are for amplifying the sound. In fact, the connection between the two big points is to amplify the sound. Only it is needed to recover a broken device.Thank you,

I have the same HU as yours with 2/32 memory and also want to update, but could not download TWRP for the 2/32 HU. Is there any possibility getting a copy of yours?Thank you,
I had already found the post where it was described the unlocking of the bootloader with the photo you attached.
[Tutorial] AC8227L head units - how to unlock the bootloader
I had already tried but with negative result, the system wrote unlock failed.
In the post was also put this: In the image I attached, you're looking for the points marked 1 and 2. The caption on the image suggests they connect to Volume Up, but on every unit I've seen these points connect to Volume Down. Your mileage may vary. The layout of these points can vary from model to model, but they're always in this area.
Points 1 and 2 I used them for a hard reset after a total lockdown. (Big brick), fortunately fixed by restarting Flash Tool.
However, it does not matter, now I have no intention of taking the radio apart and trying.
Even with the bootloader locked, I rooted, installed TWRP, updated ROM, installed FMRadio with RDS, fixed the Mac Address that changed with each reboot etc.
Before doing anything, I had done a complete system dump including the userdata partition.
Thanks again for your concern.
Thanks much appreciated!I got the recovery partition from a ROM downloaded from the 4PDA site: https://drive.google.com/file/d/1dN6THOa6UfqepPvso1QN4_-kr66w_HHN/view
With Flash Tool, your scatter, flash file of the recovery partition only.
I have tried various recoveries and this one works.
Warning, it is not possible to make a full backup or backup of large partitions, as HU freezes, the monitor wobbles and then resets.
Small partitions all OK.
Zip file installation OK.
I have read somewhere that this problem is known and affects 1/16 and 2/32 systems.
For a complete backup of the ROM I used Flash Tool's Readback and with WwR_MTK I unpacked the ROM by obtaining the various partitions.
Before doing any operation on the ROM, always make a full backup.
This saved me in many HU brick situations.
Hi and good luck.
I use the USB cable out from radio, i ever use it to flash...@lolloxda ,try to use 4 pin USB and again try with the wire method with two test points. When i was in your situation my 6 pin USB did not the job. Im giving you link for rom im using atm on 2/32 i hope it will help you.
