Hello, can I install this version for my head unit ?

Csn2_10132020_181154
[Android Head-Units] Kimo2014:
After ising this method

. Upgrade

- run AndroidTool.exe

- download and install this APK

- run it and click "Go to Android10", the device will be rebooted and BRICKED. APK kills loader and boot partition!!!

- connect your laptop and head unit via the discovered OTG USB

- AndroidTool should reprt "Found one MASKROM device"

- hit run button;

- wait until the competition.

The unit will be rebooted, data partition will be formated and the unit will be running andriod 10.

3. Post upgrade

- download the most recent firmware

- put it on USB stick

- do an upgrade using this USB stick

I try many firmware, but the head unit was broken on boot

What I must do plz ?

Complete noob on these android head units. I bought a 2018 F150 that has an PX6 unit with device name rk3399. Android version 9. Suddenly the AC controls stopped functioning so I am trying to crash course it.

Regarding firmware, can I upgrade to any PX6 firmware? The one I have is dated jan 2020 and I see one on the google drive from july 2020 that is also android 9. Do I have to use that or can I upgrade to one of the android 10 firmwares?

Thanks in advance and sorry for stupid questions. Its over 100F in texas right now and I am dying without AC otherwise I would spend more time using the search function.

Hi All,

I'm new to the forum, I've read several of your posts and I would like to ask you for help :).

My car radio with Android 9 system has not allowed me to use applications or make updates for a few days. For example, YouTube, GoogleMap and other Google applications no longer have an audio signal.

All updates are not allowed. How could I solve it?

I tried restoring it to its factory state but it still doesn't work.

Could I do an update? If yes, could you guide me with the download link?

Here are the details of the car radio (also in the pictures):

MODEL PX5

Hi all

I have registered here in the forum to say "thank you" for this great collection of knowledge for the CNS2 radio units! I have recently updated my Pumpkin AA0495B with the MCU 08152020 and Android version 202009011014. It was successful and I found some nice improvements (for example the Radio application). So far no issues due to the update- fingers are crossed.

Next step will be to update to Android 10, I have ordered the male-male-USB cable :)

The biggest issue I am currently facing is that the Google Assistant refuses to send Whatsapp messges (no number available for whatsapp) and it does also not use the bluetooth dialer for phone calls (it just hangs when I ask to call somebody from my contacts and nothing happens). I guess this is because the included bluetooth dialer is not properly "registered" as phone app. It works if I install linphone (SIP client) for example- but I would prefer to use my phone via bluetooth.

I will continue investigate/try to find some solutions. If anybody has any idea, I am happy for any hint! Or maybe the update to Android 10 will help ;-)

Thanks again for your great work here!

Hi All

so i have updated to android 10, on a px5 Unit ( installed in ford fiesta ecoboost 1L) 2017 model, but now the touch screen does not work. did i do something wrong or what can i do to get it working? ( i can use the screen with a keyboard pluged in ( those small little bluetooth keyboard things) so i can navigate the sytem but im not sure if i should be setting a setting or something?

update - got it working.

under the car settings ( in the setting menu) and then factory settings (pin-126) i had to change the FTJ setting. i dont know what FTJ stands for, but that resolved my issue... so i finally went to bed at 4:30 am haha, but hey its working. cheers guys

I have a 2023 firmware and also a 2022 MCU for the PX5 ( they say its android 12) but i remember loading android 10 myself, and then got the firmware from the manufacture and loaded it, it says android 12, but yea.

if anyone wants it, please PM me, so i can figure out how i can share it with everyone.

Here is some pictures i just took of the firmware and MCU version

Hi everyone! I've been trying to fix a friend's unit but i couldn't find any solution, so i came here.

The problem is: He was using zlink app, then he tried to update it, deleting the app and then installing another one. Then the app appeared to be deactivated.

The "important" specs i've seen are:

MCU - CSM4_D....

PX5

Android 10

I've been through every forum thread looking for that info and everything related. I've installed so many zlink apps...

I've found (after getting the missmatch-channel error) that the zlink sinuowei version kinda works, but i can't activate it.

I thinks the recovery mode is limited too, i don't know... i couldn't install any kupdate....Any help is much appreciated!!!

No, because this is a backup camera which is only activated in reverse gear. No possibility to get it working as you want.

May be one idea, which needs some additional hardware:

[Android Head-Units] almora9:
do you have any suggestions for a better quality gps antenna for px5?
[Android Head-Units] rigattoni:
It´s not a matter of quality, it´s always a matter of the positioning.

If you have a car with a heated windshield, or a metal-coated windshield, you need to use an external GPS antenna on the roof.

Otherwise: position the antenna directly on the dash as far as possible to the front. Alternatively directly under the dash cover. Make sure that no metal is between the antenna and the windshield.
[Android Head-Units] rigattoni:
Just get in contact with your reseller and ask for an update. Explain the problem and may be they have some sort of fix for this issue.
[Android Head-Units] rigattoni:
Sorry, but have you ever taken into consideration that the rear camera is broken?

Did you measure the voltage at the camera?

Did you ever tested the rear camera at any other screen like TV???

Before messing around with other firmware, this would be the most important part of analyzing issues like that.

Hello everyone,

is there any way to get the Google Assistant to work again for making hands free phone calls on a CSN2 PX5 (Pumpkin) radio under Android 9? In the past, you could teach the Google app to make calls (if your cell phone was connected via Bluetooth) using the app called "Bluetooth" on the radio. It had worked fine before. Due to the unstoppable updates to the Google app and services, nothing works anymore.

Mods are not an option because, as far as I know, there are none for csn2.

As far as I know, there is no alternative dialer for csn2 either.

Upgrading to Android 10 (if that would help at all) is not possible, at least not with the kupdate.zip that pumpkin sent me.

Very frustrating. Is there perhaps any work around?

[Android Head-Units] Strike03:
Thank you and please correct me if i am wrong. I thought the ui is a part of the firmware and every reseller makes their own firmware with their special ui? Isn´t it so? If it is like i understand,, that the ui is part of the firmware.... May 8th( not 5th ;) firmware is from Pumpkin with their Ui which is the same as mine (20190507172) at the momen and wich i can use to downgrade if i don´t like the new one.

The newest one is June 18th 201906180853 . This firmware is from Klyde? (Pumpkin? Kanor? ) like all the others except the one you said it´s from Pumpkin : "February 20th 201902201912 + MCU CSN2_0192019_154914 from Pumpkin ND0294 suitable for us, contains another launcher and has a bit different appearance of applications. "

So i am a little bit confused. How can i downgrade to my Pumpkin Firmware with their ui when there is only the Klyde Firmware vom May 8th. Or is this the firmware from Kanor with their ui?

Or if i am totaly wrong, the ui always stays the same ,depending on your seller of the unit no matter what firmware you use to upgrade/ downgrade? It´s not clear for me which firmware is from whom at the initial message of your thread, except the one you said it´s from Pumpkin.No offence! :) maybee i begin to get mad ;)
[Android Head-Units] Strike03:
I found out myself :) I updated to newest firmware (June 18th 201906180853) of you( Notation: it was only possible to update via usb stick, sd card didn´t work). It has a different ui...i am not absolutly happy because there are no widgets to install, except the installed one of the Radio/ Music Player and Clock.But you can´t resize them. Both are at the startpage..And there isn´t a button on the startpage to see all apps, you have to scroll left through the pages.There isn´t a seperate overview like on the Pumpkin launcher.

But i tested the Radio app and it works perfect!!!! I am very happy, it works like on the Xtrons Unit. Perfect AF if you lost signal while driving (in 1 sec radio changes frequenz to the alternative one) and the Radio finds every Station here.I live in a mountain area where frequencies of a Radio Station sometimes change...perfect...!!! :)))))))

Much better programmed as the Radio APP of Pumpkin.

So do you think it´s possible to extract the launcher of Pumpkin and put it to the new firmware ....I would like to keep the new firmware , but with the launcher of Pumpkin.

Thank you for your thread!!!!
[Android Head-Units] _yuzo_:
Android 9 is not well know for us, we even do not know if that is related to this thread. If you can take photos of internals of your device we'll at least try to identify if it is related to this thread. You can try to root the device using this link (translate that with google from russian). DO NOT UPDATE SuperSU binary, otherwise you can get a brick.

I'll try to extract the files from pumpkin firmware to check if there is another logic, but most probably everything is in CarUI.apk as well. All units have the same launcher, except Pumpkin. So there is no difference between Klyde, Kanor and others.
[Android Head-Units] joehjay:
post some pics of your unit and unit infos from About -> Tablet Info

Development option can be enable with THIS APP (after install and open it, choose APP EXPLORER, then select SETTINGS, after that scroll and find DEVELOPMENT SETTINGS and push Launch button, after that enable the development setting as usually)

Development option in the new firmware requests a PIN or Password code that is the same for Lock Screen; so into the device is not enabled the LockScreen Menù and not set a pin code or password from default. If you want set a password or pin and test this, you can do it with the same apk posted up, making the same steps for the app SYSTEM -> DefaultLockScreen (after push Launch button, you can set a pin code or password that can be used for unlock Development Option)

---------- Post added at 08:46 PM ---------- Previous post was at 08:16 PM ----------

The launcher are the same only in name :) comparing the internal files and refered codes, they are different, i work on this from few days but with no luck :( at the moment, I've extracted, decompiled ecc. launcher from Erisin / Pumpkin and June Fw

So in the June Fw the stock launcher is Launcher3 in the other ones the stock is Launcher2.

For enable the 2nd launcher:

1. Root the device

2. With a "Root file manager" go to the folder -> root/system/app-priv/Launcher2 or Launcher3 and install the Apk

3. That's all.

In the June Fw thw Launcher2 have, in half, the same graphic of pumpkin (without the WinCE graphic)
