Hello, i am a newbie in this forum and i dont know if this is the right place in the forum to publish my problem. Anyway, recently i bought chinese android headunit with the following specs:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
i have done a little reasearch and this SWL12B is somehow changed by the chinese seller and actually it is XY Auto device with software F9212B. So, i have done Fake Test Device and the following results were given:
Since i dont have DSP app installed and i needed better bass sound i saw other posts about flashing firmware with different version which has DSP, i downloaded SP Flash Tool and installed the MTK drivers. I saw this video on youtube:
, so i downloaded the correct software from the video which is based on 8227L chipset. So i downloaded from file.xygala.com firmware 9216CJ downloaded file: gongban_9216CJ_hw_12ok-ota-v7.3.7.zip. Then i loaded the 8227L scatter file in second row (i will attach image below)
So i flashed the device successfully and everything went well, the device restarts and it started normally. Everything works except the sound from radio is only on one speaker. I could not fix it to sound on all 4 speakers. Below i attach screenshot of the new firmware:
This night i tried to flash the software with my old firmware (F9212B) downloaded from fyle.xygala.com. but SP Flash Tool did not recognize my headunit.
Please help me with some solutions, tomorrow i will try again to reflash the software again. I really need your help guys as i dont know what to do right now.
Thanks in advance to all who are willing to help me.

Hello everyone. Buy a unit with Haoling frimware 00009_V0001_20191128. To improve it a bit, install the YT9216B_00002_V004_2101012_HIFI_V3 frimware with SPFlashtool. The new frimware was working fine, but the drive seemed slower, so I decided to look for another lighter frimware without so many extras. My problem comes when when installing the new frimware I forgot to uncheck the Preload box and when I realized I got nervous and disconnected the cable, this caused the display of the unit to remain black and illuminated.
My first failure was not to backup the drive in its original state, and since then I have been testing frimwares without success, the most I have achieved is having a home screen with 3 boot options and an arrow moving in a loop, but at not having physical buttons I can not do anything.
I have had access to a unit equal to mine, to which I have been able to make a dump backup, but I am unable to load it, since the unit sounds as if it is constantly connecting and disconnecting and does not complete the loading of User.
The Test Point system does not seem to work for me, or that or something I am not doing well and I cannot find any video to see how it is done.
Ultimately, I don't know if my unit has a fix or if it will stay like a brick.
I hope you can help me, thanks

Hello. Has anyone happened to me? Is there no way to fix a failed Preload installation or to know what Frimware can I install to recover my drive?
Thank you
Disconnect the black connector from the radio for at least 30 min..next, it should boot directly to system..if it freezes at the Android logo, you have installed a incorrect firmware
Try this brand new guide
So the Android head unit on the family's Tucson is a Beryllium brand Head unit installed by the Hyundai showroom. It boots to a pure black screen, radio doesn't work but Bluetooth does. I think the cause was from a failed firmware update and would like to know how to put it in recovery mode or are there any software I could flash in my flash drive to fix it.
Apologies for the bad photo, the vehicle is in use atm and this is the best photo I could find in my phone
The unit if memory serves me right from the device info was rckPX2 I think? Android 4.4.4

Any update for this?
Hello, I have a HU. I installed a Launcher, set it as default, and now it can't go to the Android menu, the Bluetooth is working fine, just a BMW logo looping. I tried to fix it, accidentally bricked it as well (deleted everything with SPF), because it's now not recognized by my laptop. I got my original firmware from the manufacturer I think (link K2001N.img), but they didn't really tell me how to use it. So currently the reverse cam is working, the original BMW menu is working, the Android part is a huge black screen (with back light). I also tried to find test points, with not much luck. Can someone help me to find the test points, and tell me how to use this .img file? Only one RST button is present. I already tried a few test prints with no luck, maybe I can memory dump this image file?
HU details (so others find it in the future)

Hi Guy's
I tried to install the new version of my head unit, which i got from xygala. After the update finished i got stuck on a bootloop.
Unfortunately i did not make a backup...
Accidently i formated the device incl. the bootloader - now i am stuck with a device which isn't doing anything.
if i try to use any scatterfile from any 9216bj roms, I'll get a DRAM error.
Is there any chance to revive my device?

Hello everyone. My name is Julien and I'm French so sorry for the translation ^^ I recently replaced my Chinese car radio under winX by another Chinese but Android and as I expected I have some problems with it. I specify that it is for a bmw e46 330cd. First the built-in eq is really horrible even with my old Chinese the sound was much better. Here is the eq in question

There is a second one in the canbus settings but nothing happens when I change the settings would you know why? Here is a photo of the eq which is not working
Then it does not memorize radio stations or volume settings in the Android part. Finally is there a better firmware for this HU? I will post pictures of the exact model I have. Thank you a thousand times for the time you will take and again sorry for the translation ^^
Hi.
I would ask your seller how to correct all that.
If not answered , I would return this for a refund.
hello and thank you for your answer the seller is only an intermediary and does not really know the HU ^^ I will have to manage without him. I think that changing the firmware could partially solve these problems.
if ever a charitable soul had a rom for me that would be great. I see plenty but not knowing enough I'm afraid to put a bad one and end up with a breeze block
some more info if it helps
