Headunit Mstar full AOSP cedric3

Hello respectfull people☺
I've got a headunit unbranded and written on the screen that it's android 4.4 but if I tap on the label android version I discovered that it's android 4.2
Anyway that's not a problem because it works good
My question now is how can I upgrade it to android 4.4 kitkat?
Other question is if I can't upgrade it so can I make a format to the software and install a 4.4 android to replace the 4.2????
Thanks for you all if you helped me in that issue.

No one can help unit youve shown us something that can identify your unit, post a pic of your settings/about screen that shows your MCU type.
What we can say is that if its got an Mstar processor its deffo NOT an MTCB/C head unit, it may be an AN21-U unit, theres a thread for them in the General forum.

informations about the headunit is full AOSP cedric3 on Mstar.. and I will be thankfully if you give me a link to catch any answers from it
I don't know why pictures of the headunit I can't uploaded here

You will have to look for a thread with "AN21-U" in the title in the Android Head Unit General forum (its a very long thread started at least 3 years ago with millions of views) - in order to post a link I would have to look, so you may as well look yourself.

Ok thanks [emoji1] [emoji1]

UltraOcta-T8 upgrade to Android 8.1

Hi all
I have a 9" UltraOcta-T8 (I think it is the AllWinner) and it is running Android 7.1.2
Is there an upgrade path to Oreo at all.
Here is a pic of the About screen showing MCU and System version ( for some reason I cannot upload an image)
MCU version: 5.3. 19-63-84-C06101-170705
System Version: V9.2.2_20171013. 154052_TW2-FD
Thanks
Lance

I was hoping you had a solution too, I love the head unit but I think it could be a better experience with 8.0 on it, it's been over a year without a reply on this thread.

Yes, there is an upgrade path using Phoenix Suite. I upgraded from 7.1 to 8.1 around 2 weeks ago and the head unit now feels snappier and it hasn't crashed yet when using various sat nav apps which it used to sometimes on 7.1. Boot time is slightly faster and I've found it connects via bluetooth to my phone automatically every time I get in the car. Under 7.1 it was quite sporadic.
There is a post on the main T8 Allwinner thread which you will have to look for. You'll need a laptop, Phoenix Suit, 8.1 ROM which is in the post (I've now flashed the JP variant of 8.1 which is stable), Male to Male USB cable to connect laptop to head unit.
The instructions in said post are a little hard to understand, but it only took me about 15 minutes after I'd downloaded the software and ROMs.

Thank you, this got me pointed in the correct direction, only thing I'm worried about is losing BT capability since I read that happens a lot.

some high-tech may support upgrade
most devices can't upgrade from 7 to 8 version. It depends on whether your head unit support upgrade. need to reach out to seller.

That was one of my concerns also, I had no issues though. Just make sure you take note of the config in the extra settings. Once you've flashed your final ROM, check the settings are the same and reboot the head unit 3 or 4 times (not sure why, but seen it said a few times).

You can upgrade from 7.1 to 81 on the UltraOcta T8 AllWinner devices. It's just a bit of pain as you need to use laptop etc... but once you have everything together it's quick and easy.
The only thing I'm not sure on is the downgrade path (8.1 to 7.1) should you need it. Thankfully I've found 8.1 (v9.3.1_20181109.180710_JP3-FD) to be much more stable than 7.1 (9.2 JP1-FD).

Which thread did you say the instructions were in?
I can't seem to find the thread when i search for allwinner t8 update

Update JOYING PX5 android 8.1 to android 9

Hello everyone
I have since yesterday a Joying JY-UO135N4-OBD, MCU number: TP6735D 0.43 under android 8.1 that I want to upgrade to android 9 because my OnePlus 6 is under 9 and can not connect USB on the Joying.
Is there an update?
Thank you for your answers.

No there is no update and I'm for 99,5% sure there will not come an update anymore now that the new Intels are coming in and the PX5s are slowly phased out.

Eunavi claims they will have a 9.0 firmware for their PX5 units this month. Maybe others will update as well.

I'm a little disgusted to learn that, I should have better information before.
Is it possible to make my Joying 8.1 compatible with my OP6 Pie in another way?
In bluetooth everything works very well but in usb (for android auto and mirror function) my OP6 sees the joying but the joying does not connect to the OP6.
Thank you for your skills

OP6 Android 9.0 with Z-Link is working on the new intel joying units....

I believe you can attempt using the trial version of Headunit Reloaded Android Auto and if this works out. You can try out using the full version.

I can confirm this to work with Pixel 2 running Android 9.0 using both wired and wireless.
It's not installing Android 9.0 directly onto the head unit but it will mirror any source android phone as long as it's 4.1+.

The OP asks whether he can upgrade his PX5 to Android 9. Not whether he can use an Android 9 phone/device with his unit.
That's a big difference and mirroring your phone to your head unit might be enough, but it is always a big functionality limitation when comparing it with the full head unit functionality.
For me the only concern with older Android versions it the lack of support when it comes to security patches by those Chinese suppliers. Joying (and all the others) simply stop supplying security updates even though the Android 8.0 version on the PX5 is still fully supported.
Using Android auto or headunit reloaded does not change that. It might even make it worse (and especially with z-link)

But seeing that the OP may be staying with his current PX5 I took the liberty of suggesting an alternative to Z-link. Seeing as I have hit the same snag as him with my PX5 and Pixel 2 running Android 9.0. So as a reiteration to the previously mentioned:

You are completely right. I had overseen his second question. sorry.
Headunit reloaded should/might work.
Z-link only works with phone versions up to 8.1 with the PX-5.
The new 9853i (8.1) does work with Android 9 phones. It might be worth trying to install that z-link version onto the PX5 to see whether that works.

I thank you all for your answers.
I made a cross on a hypothetical update of the PX5 but if an application can replace Z-link to run my OP6 pie it would be great.
Or a custum ROM ....

I have an OnePlus 6T and I have the 10.1" octacore 4/64 GB px5 8.1 joying unit and I contacted them about it. They say they are working on an update to fix it. So... We shall see, not holding my breath. I plugged in my backup Moto E4 and the works with z link.
What I'm trying to figure out is what update my unit needs since they have their Intel altimont update on their site and I'm not sure if that's compatible.
Edit: ok so I see that I have a QD unit, I reached out to joying to see if there's any recent updates

Hi, is it possible to update a firmware/ROM from android 8.0 to 8.1 using Joying web updates? My HU is Xtrons MCU KEQ, but is essentially a Joying hardware with px5 4/32g.

No.
The PX5 8.0 firmware is an ARM64 android. The intel airmont 8.1 firmware is an x86_64 android.
They are completely incompatible. And then there is the differences in other hardware requiring other drivers.

Im lookin to replace my com.syu.amp from my actual 8.0 system. How can I get a new/different one? I saw that Joying is showing a new parametric EQ in the 8.1 set. And the HU dont have a DPS hardware. So.. Is there a way to take some Archives from android 8.1 to use it on 8.0?

I don't think so.
And the com.syu.eq is the "visual" equalizer. I'm afraid the difference in hardware is too big to make it work. And I also think that other libraries and drivers are required.

My problem is that EQ is not doing that would be at all. 7 bands and and every one of this acts as HPF. Its imposible get a good spot.
On system/priv-app/ there are 2 folders related to audio, one is the 180000000_com.syu.amp that inside has an .apk called AMP.
And de second folder is com.syu.eq that has the Eq executable.
Maybe trying with the last Joying web firmware to px5 from november 2018? What do you think?
Thanks again for your help.

Sorry. I really don't know. I already mentioned my doubts and have no further experiene with it, and know nobody who has.

Would it be possible to see if the Z-Link apk (from new Intel Joying) can work on the 8.0 (PX5). If someone can extract the apk and share it from the device itself? I've tried downloading the firmware, and extract the system.img but I can't go any further than that for now. I need to figure out how to extract ext4 images on a mac.

Help identifying head unit FUNROVER

You have a Sofia unit. That unit is running Android 6.0.1. That does not support phones with Android 8.x. There is no firmware that will help you.
You should better take a look at HUR: Head Unit Reloaded. It is made by an XDA developer.

What info? From the supplier or the website or on your unit?
I don't see that from your images.
Also: A Sofia running on android 8.0? That would be the first that I know of (but I don't know everything , not by far )
Your 2nd image shows a Bluetooth version of 6.0.1.-23. That version is not correct, but is shows Android 6.0.1 with some kernel version.
Anyway: Even if your Sofia is running Android 8, there is no (custom) firmware available that will allow it to pair with an android phone on 8.x or newer.

Thank you for the explanation surfer.
That means i cannot install any of the firmware on this forum?

Probably not. Maybe you can install the gtxaspec custom rom, but only if your funrover is 100% identical with a Joying Sofia (which is possible).
Normally there is a fyt.prop where the company is defined. For Joying that id is 43. So even if you use that custom rom, you first need to change the id in the custom ROM to the Funrover id, otherwise your MCU will give problems.
And even in that case: your android phone 8 will still not be supported in Android auto/Easyconnected.
So my advice: Don't even try that route as you will not have any support.
Go for HUR like I advised in my first post.

Good to go. Looks like original firmware, all stock, installed today with no issues.
My multimedia is Preling Tesla style for Opel one. 4/64 ts9. Dont think it is kind difference between firmwares, once disassembled a lot of them, this one by tw.
As well used magisk root recovery, all is working.
Asked seller for new firmware for one hundred times and found it myself on internet by mistake =). BTW all this is not 9 android like it called in info it is 8.1. Also get info regarding upcoming android 10. Will see. Personally waiting for RedMode firmware because of buttons reassignment possibility.
PS. Is it any good rom maker or hard experienced app modifier with this kind of multimedia?

Yes, I asked the seller for new firmware and mcu updates, too. More often. They answered only, no new firmware at this time. I could not believe that because mine was released on december 2019.

A couple of small improvements. I think this is the last available ROM on the market now. Have root and launcher with opel sedan logo on desktop implemented.
Have one annoying bug with original Bluetooth application. It is double skipping forward backward ie one press two track forward. Think that problem is partially hardware issued.
BTW all the firmwares for this multimedia is 8.1.
Hope somewhen redmod for ts9 tesla will be released once i need key relearn feature.

A couple of small improvements. I think this is the last available ROM on the market now. Have root and launcher with opel sedan logo on desktop implemented.

Thanks for your reply.
So, now I'm pretty unsure to keep my stock android 9 and waiting for upgrades or downgrade to android 8.1
Do you know if root is working on android 9?
What will you do in my case? What I want is root and future updates, of course.
