Hi there,

why the device wont be updated ?

I get a error when I use the update method in settings (ziped rom on a usb stick).

And when I try the method to unzip the rom and boot with the usb it wont start the update (it reboots only).

Im right now on feb rom.

Any ideas ?

Best regards
[Android Head-Units] ramnkc:
Extract those files into XYAUTOUPG folder. Make sure you formatted your flash drive into fat32 then extract all files into XYAUTOUPG folder. All extracted files must be put under XYAUTOUPG folder directly.
[Android Head-Units] EagleSoldier:
Hi,

i did this, but device only reboot without update.

I will try some stuff, maybe it will work.

Best regards
[Android Head-Units] dude-nl:
Make sure you download the file with the term "flash" in it. The other one only works with the flashtool.

Just updated mine 5 minutes ago and made the same mistake...

File name: YT9218C_00005_V004_20190522_HIFI - UI2 FLASH

So DONT USE: YT9218C_00005_V004_20190522_HIFI - UI2
[Android Head-Units] EagleSoldier:
Do you have a link for the "flashable" version ?

I dont see a rom with flash in it.

Thanks

Update Android and MCU help with WiFi issues?

Hello All,

I will update the Android and MCU but I would like to ask if anyone knows if this will help with the intermittent connection I am having with WiFi. Sometimes it connects and sometimes it doesn't. I have looked in other forums but have not found anything related to WiFi issues and this HU

Thank you.:fingers-crossed:

Firmware 20190622 with MCU 3.1 via flash tool

Updated to latest firmware via memory dump. links updated in first post.
[Android Head-Units] cafsta:
Okay...

So I've cut up a USB cable and attached it to the heat units cable.

I then tried the recovering of my head unit. I plug the USB cable into my laptop, the head unit side lights goes on, the laptop makes the sound that a USB has been plugged in, it shows in the Taskbar then quickly it sounds again indicating the USB has been unplugged. The head units side lights stays on but on the laptop it shows the USB is unplugged.

I do assume there's something wrong with the cable. I tried fixing the cable 3 times ago I know it's not how I connected it but possibly the difference in wire thickness in the attached cables.

I'm any case, does anyone know where I could possibly buy the 4 pin cable which attached to the heat unit. I can't keep cutting up all my USB cables.
[Android Head-Units] grvdggr:
I don't know what you're trying to do right now.

However, you connect the cable after you have started the Flash progress.

It's not supposed to connect to your PC like a USB memory.

The unit should not have a external power.
[Android Head-Units] cafsta:
Okay steps I was taking...

Laptop on with flash tool open. Head unit is unplugged with no direct power. Only the 4 pin USB cable is plugged in at the back of the head unit.

Flashtool is loaded with scatter file then I plug USB into the laptop. I notice the head units side lights, (power, volume, etc buttons), goes on but not the screen itself.

In Flashtool though it is not picking up the head unit.
[Android Head-Units] grvdggr:
You are suppose to connect the USB cable after you push flash.
[Android Head-Units] koontzy65:
Did someone found the adaptor that plug into the back of the head units with a female USB on the other end ? I was trying to find the adaptor or at least the connector name to build my own and still nothing
[Android Head-Units] cafsta:
Okay so thank you again to OP for the amazing help in his first post.

My device somehow got stuck on the screen when the boot animation ends.

I finally got around to fixing my device and flashed the device using the following firmware: YT9218C_00005_V003_20190225_HIFI ROOT TWRP

MCU was on 3.1 with this flash.

My problem now is that the quick boot function is no longer working. My device cold boots every time now when start.

I also previously used code 8888 to access the factory settings option but this code and every other code I've tried just does not work.

Can anyone assist me with the quick boot and factory settings code please...

The MCU was naturally on 3.1.
[Android Head-Units] kaiserferi:
have you tried FCC launcher?
[Android Head-Units] Ipse_Tase:
All the cables are "standard" - as much as such thing exists when it comes to Chinese stuff. You can get the 4 pin or 6 pin USB cable on Aliexpress or Fleabay...but it will take an eternity to get to Canada.

---------- Post added at 11:47 ---------- Previous post was at 11:43 ----------

You went too far back...you need a ROM after June 2019. Find one of the December ones now that can flash. It will have the standby function too which you absolutely need.

Search either here or on 4pda.ru what works for your unit...match the RAM/FLASH sizes.
[Android Head-Units] cafsta:
Thank you for the reply.

I will get a later firmware then see if that gives me what I need.

Thank you again.

Hi [MENTION=9936717]viktorsaari[/MENTION],

I have memory dump of my radio 9218c_0005_v004, 8227l. I do have the scatter file too. It was working perfectly fine and I rooted it too.

But while I was modified the build.prop to get the multiwindow feature as mentioned in your thread and rebooted my system. It went into bootloop.

I tried to flash a rooted firmware for my device which I had never flashed earlier. I used to scatter file mentioned in the same rooted firmware zip. Everything finished in the SP tools with success and I rebooted the radio but It still didn't come up. Just a black screen.

Now when I tried again to connect with PC, PC is not able to detect it. It's not even appearing in the Device manager.

I have the backup and everything. What can be gone wrong here?

1. Does that rooted firmware contained wrong preloader/scatter file?

what are the solutions so that PC detects it back as a preloader?

Thank you for any help.
[Android Head-Units] DonS:
I had the same thing. I accidentally formatted and flashed the wrong preloader. To recover, I had to solder wires to the test points on the main board and connect them to a switch. I pressed the switch while plugging in the USB cable and released the switch when the hardware was connected. I then flashed the correct preloader. I then unplugged the USB cable to power off the head unit. Then I plugged it back in and flashed the correct ROM.

1. Created a preloader backup.

2. Created a rom_0 backup. Just one clarification required. Can you please tell me what should be the last address(length) so that it includes everything. I have put start address of BMTpool as the total length of backup so that includes whole userdata partition.

So start address- 0x0

Total length - 0x738A80000

Can you confirm if this should have everything to restore in case of any mishappening?

[Android Head-Units] amit_coolcampus:
It worked for me and I was able to restore the preloader and user partition.

Thank you so much for sharing the RU link. That video saved my ass. Although I used my own preloader and backup but I did it correctly.

Post preloader, I flashed back ROM and user partition. I'll try to connect it with power supply and will get back to you in case it doesn't turn ON.

Edit:

It still shows black screen. After restoring preloader using test point, my computer starts detecting it. But when I restore the User partition, it stops detecting. Also black screen. It means something is wrong with the emmc_User backup?

I dont have firmware zip file suitable for my device just this backup. Can you help me finding a suitable firmware. Attached is the screenshot from previously installed stock firmware.
[Android Head-Units] amit_coolcampus:
I need a firmware matching this configuration.
[Android Head-Units] amit_coolcampus:
Can you please look into it.

To be more precise:

1. I was able to restore my preloader from the EMMC_BOOT_1 backup.

2. Now I can see my device in device manager as well as in SP flash tools.

3. I tried to use "Formal all + Download" and "Firmware upgrade". With EMMC_user partition write memory. Both times I get the attached error.

4. I was able to restore EMMC_User . Itvgets completed successfully but radio doesn't boot up. Only black screen.

5. I also tried to download a few Firmwares and flash them but I get the same error. Even in download mode.

Error: S_FT_ENABLE_DRAM_FAIL (4032)

[EMI] Enable DRAM Failed!

[Hint]:

Please check your load matches to your target which is to be downloaded.

So precisely, I am able to flash only stock backed up ROM and that too in download mode.

Hi, my HU is on the situation that when it is turned on you see the screen with the logo and the three options of:

Select boot mode

Volume up to select

Volume down is OK

[Recovery

[Fast boot

[Normal

and a dart that loops up and down.

The fact is that my HU doesn't have the plus and minus buttons ... it has a wheel to turn the volume up and down.

(I would like to ask those who know more than me: How CAN I do to put the pictures? -Thank you.)

How to solve? In the SPFT program I am the TP method I can see the USB MEDIATEK PORT .... but I can't see Preload or Vcom ... the SPFT program stops after the red stripe at 100% .... the beauty is that the SPFT program to make me hack the HU with only the red stripe .. it worked ..... now to revive the HU it doesn't work .... it just writes to make these radios become a brick.

However I'm trying with two win 7 and win 10 computers .... and it always gives me error 4032.

the TP must be made by connecting between the two big points or connecting one (test between the two) to a piece of iron to make the ground? or to the HU itself?

Can you help me find a suitable firmware for my HU? A sincere THANK YOU.
