Android Headunit Terminology - Android-Headunits.com

As with all technology, android headunits come with their own terminology. Seemingly nonsensical the descriptions of the Android headunits

android-headunits.com

and the forums for the different MTCx types:

Head Units

xdaforums.com

This forum "Android Head-Units" is for all non-MTC units.

If you're interested in modding, custom firmware you may want to look for a device compatible with Hal9k (google for it).

​

If you want to have a unit which gets delivered with a frame and the required harness you may first want to find one for your car model and check if it's a known unit here in xda to get the required support.
[Android Head-Units] hyelife:
Thanks for all that info.

For future proofing is it better to go with the UIS7862 or Snapdragon 665? I did not see the snapdragon on the link and im gussing its a newer processor?
[Android Head-Units] TorstenH:
I can't give you an advice regarding the CPU but it is important to choose an unit with enough RAM and one which is well known here:

Good FYT units are

Junsun V1 Pro (not the Junsun V1)

Teyes CC3

Please note that the Android version is always faked.
[Android Head-Units] hyelife:
I have found 2 head units that look interesting. One is a snapdragon 665 unit and the the other is the cc3 2k version. Which one would you guys go for?

Snapdragon z900

Reyes CC3 2k
[Android Head-Units] TorstenH:
CC3
[Android Head-Units] TorstenH:
But don't make me responsible for my suggestion.
[Android Head-Units] hyelife:
Lol. Thanks. Is aliexpess the best place to purchase from or is there somewhere better with quicker shipping?
[Android Head-Units] TorstenH:
I bought there but I don't have a comparison. If you buy the Teyes I know that they have their own online shop. Maybe it makes sense to compare the price...
[Android Head-Units] hyelife:
The T'Eyes comes with 3 USB 2.0 ports. Is there a way to change it to Usb 3.0 or USB type-C?
[Android Head-Units] TorstenH:
Yes according to the description it provides USB 2.0.

I think the idea is to lay one into the glove box, use another one for a DAB adapter behind the head unit and connect one to an existing USB socket of the vehicle.

USB 2.0 and 3.0 are different standards with different transfer rates so there is no possibility to change. But I'm sure that there are adapters from USB A socket to USB-C socket/plug. For whatever reason you need that. Please keep in mind that a USB A socket is still more universal.
[Android Head-Units] hyelife:
Thanks for the info. Does USB 2.0 provide fast charge since that is the main reason I was asking?
[Android Head-Units] TorstenH:
No. But USB 3.0 is not the same as fast charging.

The intention of the USB ports is the possibility to connect periphery devices. I don't know any head unit (even no OEM device) which provides fast charging and I don't know any laptop or computer which provides fast charge. Please correct me if I'm wrong (can imagine Apple provides this feature because they have their own ecosystem).

The reason car manufacturers doesn't provide this feature is, that there is not that one any only fast charging standard. You can find more competent information via Google.

Maybe you have the possibility to install wireless charging as additional gimmick into your car?!
[Android Head-Units] hyelife:
Thanks for all the help you provided.

The T'Eyes unit gets really expensive with the $90 dollar shipping but I found another popular unit people use here and wanted to get your input on this if possible.

Mekede M6 Pro Plus

Prius Frame and Wires

This unit with shipping is about 430 vs the CC3's 540 with almost the same config (Mekede comes with 8gb vs 6 from T'eyes and both at 128gb).

I'm not sure if the the wires include a Canbus decoder or if I need one or not.
[Android Head-Units] TorstenH:
That's strange. No other shop can skip the unit for less money?

Please check first if you can find some threads about this unit to see if it's known here.

Another option could be a Junsun V1 pro? There is an universal model available, too.

That depends fully on your car and your requirements.

This may be a compatible one but I think a global Google recherche should be done.

https://a.aliexpress.com/_EuuxEel

On the other side I would expect the Teyes installation is relatively smooth and you have to decide if it's better to spend 110 dollars instead of sittings hours inside of your car to get the unit running...

But please note that there are different constellations and Teyes shows in which case their device is compatible:

Toyota Prius XW50 (2015-2021)

Brand Name: TEyes Din: One Din Display Size: 9" Digital Media Format: Mp3,Mp4,WMA,JPEG Special Feature: Wifi Function,Support Steering Wheel Control,Support 3G Network,Support 4G Network Certification: CE,EAC Operating System: Android NOTE: Supports JBL. See below for more information on this...

[Android Head-Units] hyelife:
I took your advice and placed the order on the Teyes CC3 2k. Estimated arrival is June 10.

Thanks again for all your help
[Android Head-Units] TorstenH:
You're very welcome. I hope you will be happy with the device but I think it's a good decision. Please don't make me responsible in case of trouble.
[Android Head-Units] hyelife:
I would not have a reason to put any blame on you. You've been a huge help and hopefully everything goes smoothly with the install.
[Android Head-Units] gtavo:
@hyelife I have the same car and I'm in the same doubt as you were, how is working for you the unit you bought? Do you recommend it?

Thanks!

[OnePlus 8 Questions & Answers] someyunguy:
I rooted my phone a few months ago, and it would regularly throw out this, "restart to update" prompt. I'd always click cancel, but one time, I don't know what happened. My phone was in my pocket, when I took it out, it upgraded itself to Android 13. I was under the impression that phones couldn't upgrade while rooted, but I was wrong. They can indeed update, and when they do, you lose root. So I am now trying to root it again, but want to find a way to block any updates or upgrades so I don't have to root it again, and go through the whole proccess. Thanks.
[OnePlus 8 Questions & Answers] graydini:
BUMP. I would like to know this as well! Root is nice to have, but my main issue with this forced update is that it breaks support for my nreal glasses. (I've heard hdmi in general, but didn't try) . It took me days to track down the right files to revent back to 10 and 11 on my in2017 .
[Nexus 7 (2013) Q&A] johnjeong:
Dear friends,

As we know well, it requires more space for system partition of recent android than the stock image.

I found two way to get more space for system partition as;

- Use repartition script with parted tool to obtain more space.

- System partition can be brought to the space of beginning of userdata partition by splitting.

Furthermore, I studied and tried to align all partitions by shifting them on wasted free spaces(sum up about 500MB) manually, and to bring cache/system and userdata partition at the end of eMMC by using dd command & parted tool on TWRP adb shell, however, as you expected, device bricked.

So... I cannot imagine any other possibilities to achieve goals;

- to bring cache/system/userdata partition to stay at the end of eMMC, to flexibly adjust system/userdata partitions in the future against size-increasing of next android version

- to bring and to align other partitions be fixed at the beginning of eMMC, not to waste free spaces

Is there any good idea?

LineageOS is a free, community built, aftermarket firmware distribution of Android 13, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the changelog for a full list of changes & features.

RIL (Calls, SMS, Data)

Bluetooth

Wi-Fi

Camera

Video Recording

Video Playback

Audio (Record and Playback)

Sensors

Flashlight

What's not working:

VoLTE (Blame Samsung for that)

Low haptics

Offline charging showing % (offline charge itself does work)

Camera HAL3 and 48MP back camera, this is due to Samsung's extension to camera HAL is not recognizable by AOSP (Again blame Samsung)

Feel free to report any issues you may encounter with relevant logs

Installation:

Cons I came across while using the may build:

No flash intensity toggle in quick settings.

You can access that in Settings > System for some reason

Ambient Display does not work.

Auto brightness does not work.

Navigation animations are bit stuttery, but the overall fluidity is pretty nice.

Battery usage is very steep. Even in idle.

Big portion of this battery usage seems to come from AOD (AMOLED)

System UI too seems to play a big role. Evident since I was listening to spotify w/ hotspots turned on for about 4~ hours and it only drained 5~ percent of the battery.

There's a small visual bug in the top left part of the lockscreen. The M3 primary color splashes repeatedly. (Only in the lockscreen)

😳 Friend How did you manage to boot Roynas Roms? The Assert failed dynamic partitions oplist error comes up for all his roms regardless of whether i flashed through TWRP or Sideload. I did try clean install on CWD1 factory Rom but same error.

Can you give the steps you did from flash to bootup? Also which CWD1 factory Rom are you using?( If you dont want to reveal the CWD1 Rom country code thats fine you can tell me that by PM ). Right now only Tuki1.2 & Tuki1.3 boots on my device (SM-M215G). What is your device codename?

TIA.
[Samsung Galaxy M21 ROMs, Kernels, Recoveries, & Ot] Curstantine:
I tested the first few tries with the LPOS rom, but it was missing the vendor and other required partitions so the error was thrown. The stock firmware I flashed was M215FODM3CWB1 w/ INS as the country code. (Downloaded using BitFrost)

And followed these steps:

Flashed stock firmware through odin.

Finished the setup.

Be sure to check whether OEM unlock is turned on, and RMM/KG states are anything but Prenormal (Mine was stuck in checking)

Flashed this version of TWRP.

Booted into recovery and wiped data, cache, dalvik cache, system and internal storage.

Pushed the may non EFE bulid to internal storage through adb.

Flashed it.

I didn't do anything special at all. My device is a SM-M215F though.

You should definitely go through the TWRP logs, or post it here at least.
[Samsung Galaxy M21 ROMs, Kernels, Recoveries, & Ot] OldNoobOne:
Thanks for your response friend,

So its working on SM-M215F (M21 2020) , SM-M215G is M21 2021 though but maybe somehow it can flash too. Let me ask a few more details like -

1> Is M215FODM3CWB1 Binary 3 ROM? (You can find that out by flashing incorrect bootloader BL file in ODIN, so ODIN will show error messege in red like Device 3 Binary 1 etc.)

2> Out of these 3 TWRP (TWRP-recovery-20220321.tar/recovery-3.7.0.img/recovery.tar)

which one did you use? All the 3 TWRPs didnt work on my device thats why I asked

3> Yes youre right TWRP logs I will post this time. I think somewhere it was mentioned that these roms are based on M215F so probably thats why its not flashing well in M215G or maybe Shamshung patched something in May 2023 Firmware?

4> Are any A13 AOSP/non-AOSP GSIs booting?

Thanks again for your help :)
[Samsung Galaxy M21 ROMs, Kernels, Recoveries, & Ot] Curstantine:
According to this, CWB1 seems to be binary 3.

The one in the attachment section of that post; the tar.

If the 2021 edition is using the same firmware as 2022, most probably not.

It looks like M215G is using a different stock set, maybe try flashing the stock of your device and trying again?

I tried dirty flashing crdroid and base PB AOSP, but that didn't work.

[Samsung Galaxy M21 ROMs, Kernels, Recoveries, & Ot] OldNoobOne:
Try to get the Older 2020 M21 (SM-M215F) coz the newer model M21 2021 Edition (SM-M215G) will have the A13 May 2023 update likely & the only 2 ROMs that boot (after flashing DM-Verity Disabler) are [crDroid-9.7 v2023.07.23] & TukiRom1.4.1, M215G still up for sail in Amazone.

#EDIT:-

Also, go for 6GB/8GB variant of M21, 4GB kind of less for A13, your app may shut down in middle of some work. Swap File not working on some GSIs.

This rom offers great performance and customization, delivering a smooth and stable experience. However, it lacks an option to disable fast charging, which can be a downside if you prefer to charge your device more slowly to extend battery life. Despite this, the ROM's overall quality and flexibility make it a strong choice for Android users.
