where can i find 9270? is it api23? do you have any instructions on how to switch from api23(android6) to api27(android8.1)? does the MCU have to be min. 3.5 or 4.0? all other versions of android9,10,11 are fake. follow the api. Otherwise, if I didn't have sound, I put the DSP app in the system and there was sound. But I have a DSP board, but only Android sounds and mp3. The radio played for a few seconds and turned off. yes, my preloader, I tried other things and revived the device 3 times through test points :) if you have a link to 9270, write. thank you
I don't know how do it, because I cannot get to revive with test points. How do you do it?

I'm at work right now, I don't have much time to tell you everything I know right now. you have e.g. 9270 7.3.7 firmware on http://file.xygala.com server.
I think that maybe you could change the rds setting permanently in the build.prop file, not sure. I'll check it out when I get home from work.
I have a preloader suitable for api23 android 6(fake8.1/8.1go) and a second preloader suitable for api27 android 8.1(fake9.1/10.1/11) that work with my 9216.

- firmware: 9270(00019-v001)_10.0_7.3.7 but i dont remeber if it support dsp.
- I posted my stock preloader file working with api27 here: rom-firmware-brick-recovery-for-7-android-head-unit-ac8227l-yt9217-yt9218-1-16gb
If 9270 doesnt help you, try this preloader with firmwares dedicated for 9218 xyauto but with the newest releases like at least 9.1 that you can find it on xyauto server. I see that they mentioned that 9260 is compatible with 9218.
I think 9218 may get 10.1 with 7.3.7 update soon, because a lot of folders with old firmware are empty.

In case this preloader isnt suitable with your motherboard, You know how to revive your HU.

Mainly i would try with the firmwares for your model from the catalogs as in the screenshot

friend. Thank you. your preloader works on api27 for me. Run firmware 9270, everything works, looks great. Unfortunately, I have problems with the sound. Crackling sound even when the dsp app is implemented there. I'll try to update the old mcu3.1 to mcu4.0 and try 9270 again. If that doesn't help, I'll try 9260 (compatible with 9218dh) and let you know. I don't know when I will write, there is little time and a lot of work :)

Mine is 8229 motherboard, and in 4PDA forum they told me is with energy, they give me instructions but I don't get it
What exactly do you not understand?
you have to open the device, find the test points, in sp flashtool select format/auto format flash-enter start, short the test points (best to connect with tweezers) and connect usb. if there is another board, it is possible to turn on the power supply of the device. when the format is done, you can upload a new firmware or a backup

The problem is that 8229 motherboard use energy, and the people which use it, they told me that I must use Flashtool, select start (format all+download) connect USB to PC, test point (only one) with a cable into ground and to test point, but I don't get working. I show one image

This is how I must do it, the guy told me he do it so (with this cable) but sometimes he use only a cable which put in a screw and close the one test point, but I never get it, I spent one week, a lot of time trying and nothing, I sent a video how I do it and the said me is OK how I use the cable and the test point, but I don't get working

it is possible that you have to connect one test point (+) to the ground (-), the contact must be good. The ground can also be - on the power supply. I have no experience with this. But in my opinion, you must first short-circuit and then connect the usb. and select the format ( auto format flash). try the second point, or try my guide

es posible que tenga que conectar un punto de prueba (+) a tierra (-), el contacto debe ser bueno. El suelo también puede estar - en la fuente de alimentación. No tengo experiencia con esto. Pero en mi opinión, primero debes cortocircuitar y luego conectar el usb. y seleccione el formato (formato automático flash). prueba el segundo punto, o prueba mi guía
This I don't understand, how I connect a point to a ground?

one end of the cable to the test point and the other end of the same cable to (-) ground.. the ground can be the chassis of the device, if the board is powered, it is also (-) on the power supply. or anything that is connected to the metal casing of the device. for example, the power supply is + and -.......+ 12v -ground. I can't explain it better

Why are you mixing topic all over the forum in other threads? You asked a question in the thread rom-firmware-brick-recovery-for-7-android-head-unit-ac8227l-yt9217-yt9218-1-16gb, I sent you a photo couple days ago and now you started a topic in another thread, only making a mess

Thank you very much, I managed to bring it to life with a software found on 4pda.ru software with a preloader. Thank you again!

As i see https://file.xygala.com (login:xyauto pass:123456) has YT218DL firmware on server with 8.1Go (wich is 6.0) and 9.1(wich is8.1).

The thing is that the firmware for 18DL model is pretty outdated, (Lastest releases v5.3/v6.2 from 2020r)
while other models have more current updates, (lastest v7.3.7 from December 2022) not mention newest 'fake 10 android release wich still is 8.1
