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]

So read about Viper4android, and sounds like its the thing to install - But my unit is not rooted - And all the guides make no sense to me - And there is many different.
So anyone with android know how, that can tell witch guide i have to use, and is it possible without a PC?
And do i lose all my apps etc when rooting?

Simplest way in my opinion is not to root just flash maleskys rom for px5 he has is already with viper4android root and xpose all you do is download his rom for px5 take out the update.img from zip place on the root of sdcard then go into settings click update and let it flash dont bother updating mcu if all is fine with your unit until either you comfortable or in need of it as that is the part that is more risk of bricking this is just my opion it is up to you i take no responsibility reed his thread but i do recommend

Is it that easy?
Just download that file - Place it on an SD Card - In the unit - and click update in settings?
Then i have working Viper4android?
Do i still have the same languages settings ? (danish)

Help identifying this allwinner t3 quad core k2001m / 32gb model

The attached about device screen doesn't show any real information about the headunit. I bought the 2gb/32gb version from https://www.aliexpress.com/item/Adv...32846161109.html?spm=a2g0s.9042311.0.0.mT18OW
From what I have gathered, the closest headunit I have found is the umecity one listed in this thread:
https://forum.xda-developers.com/an...mecity-allwinner-quad-t3-vw-0011-2gb-t3605401
Both have the same processor, storage, and ram. It is a low profile item just as listed in that post. I found a similar umecity verison on aliexpress listed here https://www.aliexpress.com/store/pr...-2007-2008-2009-2010/1949726_32828975208.html with 16gb of storage. I asked for the seller for more information on my model and if there are any firmware updates available, but he asked for a screenshot of the software version which only listed android 6.0.1.
The unit works great in terms of plug and play. Canbus worked right off the bat, but it is slow with google maps/spotify. I haven't tried to root or disabled and bloatware yet, and the software options are very limited. Just trying to get more information before I make any changes.

Any success??
I have the 16GB model. I am looking for an custom ROM to get more options like changing the launcher.

Hi. I bought a similar unit for my Honda Fit 2013 (https://www.aliexpress.com/item/Ned...for-HONDA-FIT-JAZZ-2007-2008/32867038767.html) Mine is running on Android 7.0.1 2GB RAM / 32GB ROM, I'm also still researching what mods I can do to this unit.

You don't need a custom ROM to change the launcher right? I just downloaded several launchers straight from Google Play / APK sites.

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

Need some Information about similar RSNav S3 Devices

Hello everyone!
Ive bought a RSNav S3 Head Unit System for my Audi A4 B8 2010.
Im trying to find out a few things of the device to root it and cusomize some things in the system. (Root, TWRP, Key mapping, MCU modification)
Do you know a device which is similar to the S3 Board i have? It could be that the Devices uses the same Software and MCU as other devices. I found some Strings in the System APKs where other Car brands pop up.
I have the complete Firmware of the Device (no source) and an update File for the MCU (.mce).
Here are some Specs:
Qualcomm MSM8953/Snapdragon 450
4Gigs Ram
64Gigs Rom
10.25Inch Screen 1920x780p
No Hardware Keys (except hidden Reset Button)
No ADB USB Port (someone said that its hidden in the case)
https://rsnav.com/collections/s3-an...system-for-audi-b8-a4-s4-rs4-a5-s5-rs5-q5-sq5
I've attached some Images of the UI
Maybe somebody can help me

So I found out something of the device.
There's a Quectel Sc600y build in. Also there's a pinout four a debugging usb port. But when I connect a USB Cabel to it, windows says that the device is faulty and can not be detected.
Must it be enabled in firmware? Can someone help me pls

Hi.
Any news? Will receive my S3 unit soon too.

No, nothing found yet.
I've done some research in this. Most of the Apps Uses Programm Parts called "com.mct" or "com.hc". But i didnt find somting about that on google.
I've seen launchers which look pretty similar to the S2/S3 launcher of RSNav. But dont found someting about them too.
Also Magisk is not available for that atm.

So i was able to root the S3 Device.
I will create a script/guide soon.
Found out that the MCU must be integrated in the System under /dev/ttyHSL2. But atm im unable to read messages from it. Baudrate is set right, but i only get cryptic messages.
Maybe someone has an idea how to read it right.

Hi mate, I'm interested if you can share how you rooted your S3 unit. I will receive mine soon and I would like also to root it. ty

You can get the Script here:
