Brilliant video, you are a skilled man, my respects🤙

[@unicornharry7995]

Oh thank god! I thought you were going to cut a hole in it for pleasure!!! What a relief!

[@greenstash]

You're truly brilliant.

[@extrememod_ahu]

Thank you but really, the credit goes to all the people who contributed with thei amazing knowledge to make this tutorial possible. Particularly on 4PDA forums.

[@4hm3d39]

Thank you so much mate. This is really very helpful but i have a question, Can we use this method on the other car panels as well?

[@EsotericArctos]

The "white stuff" is actually very important for cooling the chips. It is called Heat Sink Compound and you must replace it if you clean it all off as your unit will overheat without it. Make sure you always replace the heatsink, or make sure you don't clean it off so there is enough left to provide a good thermal connection between the chips and the case.

[@extrememod_ahu]

That is correct. Although the quality of said compound is questionable at best. We normally replace it with Arctic afte we installed additional heat sink plates to really tighten the fit.

[@Terkinstein]

You beat me to it lolz

[@TheKamlot]

Hi, can I use this method to read emmc? I have problem with which I describe you on video about backup. If I good understand shorting this test points i just allow to comunicate directly right?

[@extrememod_ahu]

That is absolutely correct. This method initiates the communication mode. I should mention however, that Test Point should only be used on a bricked device. If your head unit is working, you can enable communication mode in SP Flash Tools and use "Readback" function to read you EMMC. Here is the video on how that's done. I recommend watching it from the start or go straight here to see Readback in action: kzbin.info/www/bejne/Z3WVlH6ZnKulldE

[@iaminvincible4441]

Please help, can i apply this method, if my system is stuck on the logo and keeps on rebooting?

[@paulikiriko2103]

Hi. Thanks for the video tutorial. I have a T700 android unit with the build version as alps-mp-o1.mp5. After changing my speakers which had torn, I noticed that both the buttons on the unit and those on the steering wheel stopped working later in the day. The unit still boots up and apps can be opened and interacted with, but no sound is heard. The radio app doesn't show any station, just shows 0.00, and if you go to settings and open the infotainment section, it closes back by itself (this does not happen to any other settings section). How can this be resolved please?

[@extrememod_ahu]

Sorry but this is highly off-topic. Please search the XDA forums for solution

[@cijimpimakhoba1101]

Great Video, just got a unit similar to this, it worked for about 1-2 month and unfortunately it all of a sudden won't power on. Do you think reviving it will help to pwer on or it needs to be checked for power supply?

[@extrememod_ahu]

If you haven't performed any firmware updates then it's likely a hardware issue. You should be able to claim warranty

[@user-sy9bu4yh2l]

Hey man, great video! I got a question as you look like a person who might help me. I have a yt9216bj unit which makes an incredibly annoying cracking sound when volume is set to more than 16. It seems to occur only at peak power (like when bass hitting hard or some hard rock music going on). At this point I am asking myself if the unit is overheating or not having enough power. In case of overheating is there a thermal compound i need to replace in order to resolve this? Also, I am not using any amplifiers etc, only the 4 stock speakers i have in my car.

[@extrememod_ahu]

This is a very common issue and unfortunately it's on hardware level. Your head unit is equipped with YD7388 onboard audio amplifier that is worse than bad. Not only it overheats, but it simply can't cope with anything above 15W. The solution is a hardware mod to TDA7850 with a 10,000 mf capacitor and temperature-controlled cooling mod. Our head units are equipped with this by default. Also, if you build a small external 17v 10A power supply and add Viper4Android DSP engine - your head unit will deliver unbelievably good sound, especially if you have an active subwoofer in the car (even a small underseat subwoofer will make a huge difference). Feel free to visit our website for more info.

[@user-sy9bu4yh2l]

@@extrememod_ahu hey man! Really Thankful for the followup. This actually explains a lot as i was also thinking it overheated ao i changed the thernal compound and it is looking good for now. To be honest you got me curious with that mod but it seems rather complex. Is there a guide i can follow?

[@extrememod_ahu]

@@bobibakar could be anything but make sure to change the surrounding electronic components as per the PA2030 datasheet or your unit will stop functioning - if you are running factory software, try custom firmware and see if the problem persists. Also try MCU update if you know how to backup MCU first

[@doktorzafejs5782]

I have a similar Chinese multimedia, and the touchscreen is unresponsive. Since the USB is working, I attempted a hard reset and calibration using a USB mouse, but it was unsuccessful. I decided to order a replacement digitizer (touchscreen), but the issue persists. I suspect it might be related to the chip, and I wanted to flash it. However, when I connect it via USB to the computer, the Device Manager doesn't respond, whether the device is powered on or off, even though the USB mouse works. I'm doing this as a hobby, but I'm unsure about the next steps and what to do next.

Hello, I have a player similar to this one. I had a problem with the wiring and the output was damaged, change the component and that's it, the equipment turned on again, almost everything works exactly, the illumination of the side keys is not software, because I verified that and it's fine now, I don't know if it is the strip that connects with These keys have false contact in the key lighting area or the leds of that part were damaged when the output burned.

Do NOT use this method for what you're trying to do. This is only for bricked units. If you wish to restore to Factory defaults, simply do that from inside the Android.

Hi this is off topic. may I know the screen and touch connectors have how many pins? Is it possible to use the screen directly with raspberry pi 4 dsi? Thank you

Usually 6 pins and it is driven by GT911 chip. Some radios use different GT chip. Don’t know how to use it with raspberry, but there will be some way to do it.

[@Lamster66]

Does anybody happen to know why the newer Android stereos from China have Audio that cannot be controlled by the software equalizer and speaker position app unless you are playing the pre installed video file. Looking at the unit in the video the Hardware looks different or rather I should say more complete. Is it a case that the Chinese have found a way to loose the hardware that previously controlled the Audio save a couple of Bucks and now sell something that isn't fit for purpose? The second part to this is does anybody happen to know what parts have been omitted so that I could fit them ( Yes I'm quite capable of soldering SMT)

HAppy to hear you enjoyed the content. Test Point recovery is meant to be used for completely dead units which yours isn't. You can solve the problem by restoring your backup using SP Flash Tool. We have a full video on that as well. If you don't have backup, speak to your seller - they should have one.

I have an Android Head unit with Allwinner T507 chipset. All apps (like Google Map, youtube etc) close after a few seconds of opening. Also the android seems to be sluggish. Configuration is Android 10 Ram 4 Gb Rom 64 GB. Any solutions please.

Not sure if this is something you still dabble in but I'd love to see the flashing of an AvinUSA headunit. I'd love to run a custom ROM on that unit. I own their SD625 variant. Love the unit but hate the OS. I'd love something lighter, local, and with less bloat. More tablet and less infotainment.

[@extrememod_ahu]

You are running a completely different unit based on Qualcomm technology. Qualcomm is notoriously difficult to mod.

[@NahFam13]

@@extrememod_ahu I've learned that. It's a decent piece of hardware but the OS is terrible. It's running a custome KSW version that's really outdated. I can't even get it to update. Thank you for the answer, I appreciate the feedback.

I put the boot logo as a normal picture. When I went in and out of the market, the tape did not turn on. the logo gets stuck. the logo goes back and forth from time to time, but it won't turn on

I have a cheap android head unit from ebay. Have had for 2 months or so. Suddenly ot will do nothing. No screen light up, buttons don't light up, nothing.

Hi... Hope you are doing well. Why don't you make new videos? Please make videos on upgrading px3 head units (both hardware and software from Android 4.4) if possible. Thank you.

This is a side project that we started during Covid and we all got normal jobs and families. Making new content takes a lot of time and we simply haven't got that right now.

As for your PX3 question - we only focus on MTCx type Rockchip units with Android OS 7.x to 10

You are experiencing a bootloop, normally caused by corrupted system files. If you dont' have a full backup of your System, then your only option is to hire an expert to restore it for you.

Hi there I just got my new android 11 sterio yesterdy and tried doing a update on it I think it was a MCU,the screen froze completele and it would not take any comands so I pressed RST it turned off and does not turn back on. Ive tried pluhhing unplugging, battery check everything basically It wont turn back on. Any idea or advice?

[@extrememod_ahu]

If you were updating the MCU, then you have unfortunately broken your unit beyond most means of repair. You should never attempt an MCU update yourself. It's an expert level update and requires special equipment and knowledge as you first need to backup the original MCU and only after - attempt the update. You need a new motherboard to solve the issue.

[@vastralorde]

Hi! Thanks for the video, i have the exact same model YT9216BJ mcu 3.5 but mine was bricked, when i contact the seller, he gave me an OTA FIRMWARE, which i dont kn0w how to use, or can i convert it to a sp flash tool compatible firmware. is there any way to bring this headunit back to life.. TIA

[@extrememod_ahu]

OTA updates cannot be used with SP Flash tools. In fact, if your unit is bricked, you need either your backup or hire an expert (like us) to do the repair for you. You can reach out to us through our website for more info: extrememod.co.uk/contact-1

[@extrememod_ahu]

8227L units can only run Android 6, 7 or 8. The Android version you see (such as 8.1, 9, 10, 11) is fake. The issues you're experiencing are quite common and can only be fixed by hardware modifications.

[@extrememod_ahu]

Sounds like an issue with the Sleep mode. Try to disconnect it from car battery and then re-connect it again and see if it boots up. Do this 2-3 times. If it doesn't boot every time, then it's a hardware issue. If you are under warranty - simply return it. If not - we can take a look at it if you wish to send the unit to us to the UK.
