[Android Head-Units] sun.valeo:
Thanks. Did you notice changes after the update?
[Android Head-Units] JohnnyMHo:
Thank you. Any benefits or any changes from android 9 and MCU comparing to android 8.1 and old MCU?
[Android Head-Units] coolclouds:
This is awesome. Is there a guide on how to do the update ?

There is 4 files in the repository, which one correspond to Android 9 and related MCU ? px6.zip-20200120 and RL7A.bin ?

Thanks
[Android Head-Units] sun.valeo:
I updated to Android 9.0 with the files indicated in the picture. Rename the firmware file by deleting 20200120. See video for how to update.

I want to notify that I made this update but Android Auto stopped working, even though I have Carplay unit. I guess that this update is only for non Carplay/AAuto units.
[Android Head-Units] Dr0idFanatic:
Have you installed the zlink app afterwards?

You can try the one from the following post:

https://xdaforums.com/android-auto/mtcd-android-head-units-general/zlink-v3-5-24-apk-t4030365/amp/

I had a similar issue when I was rooting android 8, I corrupted the install and had to reinstall. Afterwards I was missing the zlink app. When I installed the app I got carplay back.
[Android Head-Units] sun.valeo:
You tried to solve the issue of sleep mode in the device. I managed to find only a shutdown delay of 30 seconds. This is not very convenient, especially for short trips around the city.

Hi the connector on the second picture is HDMI out connector. My unit come with HDMI.
[Android Head-Units] JohnnyMHo:
For anyone that wants to add HDMI to your head unit (KD-1280), you can replace the mainboard with the HDMI.

How to set the standby mode in this radio? Each time after turning on / off the ignition key, the device turns on with a full load. Where is the standby time?
[Android Head-Units] yeders:
N00b question - why would you want to get root access?
[Android Head-Units] Dr0idFanatic:
So you can modify the system any way you like and install any app. Some apps require root to work. For example - Titanium backup.

It should give you 10-15 seconds after turning pff ignition, if not check that you hooked up the constant battery + wire correctly.

If you mean how to increase the 10-15 second standby - I do not know.
[Android Head-Units] yeders:
Thanks for the info.

I notice that on Ali, the android 9 unit is sold for more than the Android 8. But it seems you've updated it?

Perhaps I was also looking at different brands of the same.

I saw 'Carbar' as a brand, do you know if Klyde is the original?

I did buy an Eonon, but am having trouble with it. Keen to hear your thoughts about this one.

Thanks
[Android Head-Units] Dr0idFanatic:
Personally I am still running Android 8. There is an Android 9 update, but have not installed it yet as I would need to figure out how to root it too. The current rooting method works for 8 only. So far have not had time to do that.

As far as the brand, Klyde is definitely a quality unit. Took it apart many times, modded the hardware, and the thing still booted in -35 C this winter and survived no problem. The boards inside the unit look really well built, even coated very nicely with a clearcoat. Sound is amazing, supports all my steering wheel controls, reverse camera, etc. No complaints with it.

Also Klyde has excellent technical support in case something does go wrong. For example I accidentally broke my screen and had to get a new one. They had no issue shipping me the screen separately.

I would definately buy another Klyde unit in the future.
[Android Head-Units] yeders:
That's really good to know. Sounds like a good unit. Any issues with power, not needing to be on all the time?

Do you have moving reverse lines on you rvc? Does the unit good boot up when you put the key in the ignition?

I'm having issues with mine,: https://xdaforums.com/android-auto/android-head-units/eonon-ga453b-2gb-32gb-car-connection-t4087385
[Android Head-Units] Dr0idFanatic:
that a completely different brand and model.

The KD-1280 has no power issues. It is has 2 power wires. One for ignition +, one for constant +. This way it gives you a 10-15 second shut off delay if the ignition is shut off. The reverse camera lines can be disabled. Do not know if they move, if i had to guess , probably not.

In my vehicle (toyota 4runner) I had to disable the HU lines altogether as I'm using the factory camera and the lines are provided by the vehicles onboard computer. So if I enable them on the HU, I see 2 sets.
[Android Head-Units] sun.valeo:
I did not write that there are problems with the power of the device. I wrote that ent a standby mode. And this is confirmed by one of the sellers of KD-1280 devices. Read the comments. https://youtu.be/G-EzUDpvP2Y

Actually what is the inconvenience. The device boots up quickly, really 15-20 sec., inconvenient for short trips around the city. You get into the car, turn on the ignition, and when you switch reverse gear for several seconds, there is no image of the rear view camera. I have to stand, wait until the device is loaded, so that the image appears. The device is very high quality, but such disadvantages as the lack of a standby mode spoil all impressions. The second significant error in the device is the only way out to the subwoofer! There must be two RSA outputs for the subwoofer. I connected the Pioneer GM-D9601 with a Y-cable and the connected Pioneer TS-W3002D4 subwoofer did not play correctly. He began to play the diffuser inside! Connected via a Pioneer DEQ-S1000A processor and the subwoofer began to play as it should. Because of this, I refused to purchase a KD-1280 board with DSP, because it has the same error with the subwoofer output! I described all the shortcomings to the seller Klyde, but either she does not want to bother the engineer, or the engineer does not care and he does not want to correct the annoying mistakes.

P.S. I hope the problem of the lack of standby mode in the device will help to solve the smart power supply for the device. In general, the conclusion is: As always, the Chinese have good ideas and even the use of high-quality materials, but in the pursuit of cheaper devices, they make significant mistakes.

Hi ,

I update my unit from 8.1 to 9, at the end it is not really a 9 , just feature update and able to root it as well with no issue ?. Version is 9 but it still Oreo.
[Android Head-Units] Dr0idFanatic:
Wow. Oh well. I guess I don't need to upgrade after all. Thanks for the info.
[Android Head-Units] Mi1o:
I really like the performance of this unit, its a power beast, but I can't wait for the update of the interface. I wished a more minimalist interface, the actual UI is outdated. I want an option to auto hide the upper bar!!! It's a waste of space.

I hope to have true software update soon.
[Android Head-Units] Dr0idFanatic:
Well thats another thing rooting is good for. Install NOVA Launcher, make default. Then install tasker and add "Immersive mode".

I've got a KD-1280 stuck on the Android logo ... How did you fix yours?

---------- Post added at 05:41 PM ---------- Previous post was at 05:33 PM ----------

So jumping those two pins during start-up will get me to recovery?
[Android Head-Units] Dr0idFanatic:
Yes it will. Be careful not to short anything else.

Shorting those 2 pins is the same as pressing VOLUME UP on an android phone...
[Android Head-Units] OlFart1152:
Copy that ... Thanks!
[Android Head-Units] OlFart1152:
Shorting the two pins got me to recovery, but apparently I need to push the update via adb. Can anyone tell me how to do that?
[Android Head-Units] Dr0idFanatic:
ADB/Fastboot disabled on this unit and will not work as far as I can tell. Tried everything possible to get ADB/Fastboot to work a while back, no go.

The only way to update the unit is to insert a USB flash drive formatted fat32 and containing px6_format.zip or px6.zip.

If it dosnt work try another flash drive. The first 2 I tried did not work...

If it still dosnt work, possibly loader is broken. In that case erase chip and reflash RKLoader.bin as described earlier in the thread. After that it should update from USB with px6_format.zip.
[Android Head-Units] OlFart1152:
How do I erase it if I can't connect via OTG? When it was running adb over wifi worked fine, but now that it's boot looped, I can't get adb to see it ...
[Android Head-Units] sun.valeo:
Who doesn’t let you connect the device via OTG? I provided the delivery information where the USB OTG input is located, which can be used even without disassembling the device.

https://xdaforums.com/showpost.php?p=82554457&postcount=40

Here is additional help from me, you can look for a ready-made USB OTG 4 PIN cable, or make it yourself or consult a specialist.
[Android Head-Units] OlFart1152:
Sorry, what I meant to say is I have not been successful connecting via OTG. I was told by Klyde that the port on the front of the device is OTG, but in reality I have checked all three usb ports with the same result 'no device detected' ...
[Android Head-Units] sun.valeo:
The seller, who does not understand technical issues, answered you, I provided Klyde documentation for internal use with the aim of training staff. Yes there really are 3 USB, but they are not OTG. USB OTG 1 input(marked with B), it is located at the back in a common block with 4 PIN input. :)
[Android Head-Units] OlFart1152:
I remember that, but clearly the training isn't in place yet ... I guess I'll have to it them up for a B block usb adapter ...
[Android Head-Units] Dr0idFanatic:
Try a different Windows device or cable. Also double check you got the right drivers installed. I'm getting Windows device manager to detect it - plugged into the USB port behing the screen. ADB however does not detect the device.

One of the pics is in bootloader mode, the second is in fastboot mode. Windows is detecting the unit in both, but neither is working properly.

Maybe the port in behind the unit will work for ADB?
[Android Head-Units] Dr0idFanatic:
Finally had some time to take some pictures. Pictures were taken plugged into the USB port behind screen.

What you want to see is "Found one Loader DEVICE" in RKDevTools 2.58

Then erase flash. It will say "Found one MASKED rom device"

Then flash RKLoader.bin back onto unit, it needs to be extracted from px6_format.zip first.

The unit should now load px6_format.zip from USB flash.

Its not ADB, no. But it worked for me when I bootlooped mine.
[Android Head-Units] sun.valeo:
A strange port, not quite OTG, but enough to load RKLoader.bin Very interesting. :D
[Android Head-Units] OlFart1152:
My cable Insignia, so maybe that's at least part of the problem ... I'll give that a shot ... Thanks!

---------- Post added at 09:54 PM ---------- Previous post was at 09:00 PM ----------

Have you posted RKDevTools 2.58 somewhere and I just missed it?

The OTG really tricky, example for apple can play it won't take any good cable from other brand using any of the front USB, it give , "please connect using OTG" , no choice have to use the original from Apple which costly ?, For AA works just fine.

Questions about KD-1280

Good afternoon. I have this device.

A lot of questions have accumulated. Who knows, please answer.

1. As you can see, DSP is present or not. How can I check this? Motherboard: KD-ZXW-MB (V1.4)

2. I have one plug with a rear camera connector. Is there a separate input for the front camera on the device’s motherboard, or should it be hooked to AUX?

3. How and where can I license TXZ SPEECH?
[Android Head-Units] rigattoni:
Hi folks,

I got this unit since some weeks and having it on bench to modify it a bit...

Android 9, API28

Some interesting information:

ADB is easy to archive. Just use Tasker and import my added ADB_Establish.xml. Run the task and the unit will be rebootet. Afterwards ADB is available until the next cold boot....

There is a nice program to use your unit indirectly with your PC --> SCRCPY

Tasker is not waked up after deep sleep. [MENTION=7838245]realzoulou[/MENTION] did some nice work and provided a small app which waits for a connected USB drive. This activates Tasker in background to run every task you need on startup.

Issues found:

On each cold boot, the unit connects to WiFi with a randomized MAC address. That means that you always get a new IP address from your router. On testing this is really bad, because it messes up the complete IP range. You need to delete not used IP addresses every day. There is no issue if it is connected by your phone with tethering.... but at home it is really crap.

Screen brightness is not really adjustable. Just 3 settings manually

Portrait and landscape application are not common. I like the landscape with the chrome buttons on top and dislike the colored ones in portrait mode.

Radio app is crap. No real RDS, no possibility to switsch from FM3-list back to FM1-list without AM in between.

No station names on buttons possible.

Accessibility settings are not stored and switched off in sleep mode, but I managed to get it activated with a small self built app. This is started on boot by FCC car launcher which is my preferred launcher.

I have some different KLYDE units to compare.

1 PX5 as MTCE

1 PX5 as CSN2

and this one....

The best UI in my units just now is the CSN2 unit with the latest update.

Unfortunately I have no pics from the CSN2, because it is in the car now...

But see the screenshots from my 1280.

Klyde did not provide the current firmware to me, so sorry guys, I am not able to give it to you.

Hopefully it will be able to get updated by RK-DevTool.
[Android Head-Units] rigattoni:
By the way...

The internals have been reworked.

A new cooler without fan has been applied.

The internal USB is now used for the front USB connector.

I didn´t try to connect it with RK_DevTool yet... may be in the next few days.

This is in discussion with Klyde from my side. I guess they will answer: No, not possible, even if there are settings for front/side cams and 360° cams in the settings.

The other questions:

DSP has settings for each single speaker. It has no digital output.

Dunno why you need to license the TXZ...
[Android Head-Units] sun.valeo:
Hi guys! Does anyone who bought this device have information on the manufacturer's warranties and the exact address of the Klyde head office? The fact is that I had a problem in using the KD-1280 device, about which I informed the seller. For the fourth month, promises have been written to me, but they can’t solve my problem, or rather they don’t really want to solve it. I managed to get in touch with the senior seller, but apparently this is of little use. I wanted to send a complaint to the manufacturer Klyde. There is no longer any desire or strength to communicate with sellers. Permanent lies and various excuses. If someone has information, give data in the subject or in private messages.
[Android Head-Units] coolclouds:
Hi ,

Perhaps you can describe your problem. We all here try to assist if can. For KLYDE you can check their website, office base in Shenzhen.

[Android Head-Units] Mi1o:
Actually, I don't really have the same issue with the bck camera. As soon I switch to reverse, the video source of my stock reverse cam goes on and i have the image nearly instantly. The unit continues booting while I have reverse image.

I have a Hyundai Tucson and the reverse video format is set to CVBS-AHD signal. The video source seems not to depend on Android sys.

The lack of standby mode is also an issue, though not my main. The big problem is the audio quality when I play music through an Android app. I use the app USB Audio Player with a Tidal Hifi subscription. Since it uses the Android audio driver, there is a lot of "data transfer" noise interference. I hate it since I am kind of audiophile.

I plan to bypass the stock Android audio by using a usb DAC to optical and use an external DSP. Though I wonder if I will be able to control the sound volume.

Let's hope that it works.
[Android Head-Units] rigattoni:
None of these issues are visible on my unit, delivered with Android 9.

Backup camera is immediately visible (takes a second) and I don´t have any bad (white) noise, while playing any *.flac files from any source.

May be they changed something on the layout of the mainboard.

USB-DAC will not work, at least there is no possibility to control the volume.
[Android Head-Units] rigattoni:
Guys,

has anyone the PIN of the System Info screen?

Should be 6 digits
[Android Head-Units] coolclouds:
Yup, Android 9 is the latest model which solve all the Android 8.1 problem. I'm still using 8.1, issue, hissing sound, Bluetooth not working on OBD2 device. No Fast boot. All this is gone on Android 9.
[Android Head-Units] Mi1o:
Guys, I am very pleased to hear that there are so many improvements with Android 9.

My seller is not providing me with any update for a while.

Can you please share the update file.

My unit sulports Android Auto and I lost it when updated with files provided in this thread, I downgraded back to 8.1.

Thnx.
[Android Head-Units] rigattoni:
It´s not that easy to upgrade to 9...

This is fake Android 9.0 For several months, Klyde has been using a new motherboard with Android 9.0 and DSP in its devices. Here in this new board, many errors of the old board with Android 8.1 are fixed. You cannot programmatically fix the errors of the old board on Android 8.1, all errors are fixed at the hardware level.

---------- Post added at 09:07 PM ---------- Previous post was at 09:00 PM ----------

I solved this problem using an external Pioneer S1000A processor. True, the processor was not tuned by the radio, but by the iPhone. In order to configure the processor with a radio tape recorder, you need an OTG cable, which is not included. I have already tempered OTG cable from China. As soon as they deliver it to me, I will write the details. See the topic earlier, I wrote about the OTG input of the device.

There are only two PIN codes in the device 8861 and 7890. There are no more passwords. The last 7890 to enter with a long hold in the menu: About the device.
[Android Head-Units] rigattoni:
No, you are wrong. The unit I am sitting in front of is API28

View attachment 5040385

You´re right, 7890 is the right one.
[Android Head-Units] sun.valeo:
If your device has a DSP, then the device has a new version of the board and Android 9.0 is installed. If there is no DSP, this means that the old version of the Android 8.1 motherboard is installed. All updates to Android 9.0 provided in this thread from the seller Belsee. Android 9.0 from this seller of fake.
[Android Head-Units] rigattoni:
It´s an original Klyde and has DSP.
[Android Head-Units] sun.valeo:
This is an updated version. I bought my device before the New Year. I have Android 8.1, without DSP.

Is CarBar, Klyde, Fongent etc.... all using the same exact 12.8" Android unit from the same developer/supplier?

I'm interested in ordering but I need advice.

Is Android 9 new or actually a fake?

Is 1920x1080p real resolution?

How has the unit been overall for anyone with the newest version? DSP sound good?

Hope to get some answers as I'm new to this but trying to understand if its worth it and if there is a certain seller that is preferred over the other?

Thanks everyone.View attachment 5046081
[Android Head-Units] rigattoni:
These units are all manufactored by Klyde.

All others are only reseller.

The resolution is real with 192x1080 and is really bright. Needs still some development in setting the brightness, but there are possibilities to get it bypassed.

...but I would like to get a good anti-glare film, because you can see each finger tip on it. May be I will cut one myself the next weeks... will see.

The DSP sound is really nice. The settings for it are self explaining and good to use.

I´m using this unit since 2 months now with the actual real Android 9 (API28)

For me it´s clear to by those things at Klyde, because you can add features if they are needed, as chosing between 32GB or 64GB, adding HDMI output ect.

You just need to send them your wishes and you will get an offer latest the next day.

The contact to Klyde (from my side of view) is really good, responses are latest the next day if you are in different time zones and you send them a Skype message outside of their working hours.

If you buy units at a reseller, you need to accept that you can buy it just as it is offered and mostly they have no clue about technical details. They have to ask Klyde for help if there are some hickups or bugs.

The unit itself with 4GB RAM and 64GB ROM is quite fast, wake up from deep sleep is done in 2 seconds. The older units (which are mostly discussed in this thread with Android 8 and older mainboard) don´t have this deep sleep, so you need to wait ~20 seconds until the boot up is completed.

The screen is stable and doesn´t wiggle around.

At this time the best unit so far in my portfolio.
[Android Head-Units] livethemountainlife:
Thanks for letting me know Klyde is the main source.

Just read thru this entire thread and I can see it looks like all issues have been resolved in newest Klyde since has new main board.

Does most apps work when installed without having to root? I would like to try out different Car Launcher apps and also use ExpressVPN.
