[Android Head-Units] typos1:
Another MAJOR factor is that there are literally 100s of different Android head unit platforms around. And there are very few experts documenting all the different head unit types from all the different manufacturers as there are in the phone world.

It took about 3 years for MTCB/C and then MTCD/E units to get their own specific forums, before then there was one massive MTCB/C megathread (one reason why the HuiFei wiki was created - to make it easier to get info without cluttering the thread). There was no Android Auto forum back then either. Anyone who doesnt have an MTC unit is in the same position as we were 6 years ago with MTCB/C units - one massive thread and thats it, unless theyve got a rarer unit in which case therell probably be a lot less info than a megathread. Myself and [MENTION=4974080]marchnz[/MENTION] are knowledgable about MTC units and after we got proper forums the need for a wiki was less and no MTCD/E wiki was created, I guess because we had a series of forums for all the info. Unlike users of other units.

There are now many other best selling Android head unit platforms other than the (discontinued) MTCB/C and (still current) MTCD/E units none of those has managed to get their own forum, let alone the less popular platforms. Hell, things are so bad that even basic info like adding the "/C" and "/E" onto the titles of the MTCB and MTCD forums so people with MTCC and MTCE units actually know that theyre in the correct place, has ben overlooked by the powers that be at XDA.

So youre better off directing your criticisms at XDA staff [MENTION=3140047]mkaaden[/MENTION], none of whom have any idea about the Android head unit market or its complexities, as is illustrated by the fact that for the last 3 or 4 years no new forums have been created for ANY Android head unit platform, even ones that sell as well as the MTCD/E ones. And the fact that basic update info hasnt been added to MTC forum titles as I said above. You need a small team of Android head unit specific people that have knowledge related to the way the market is and how many platforms there are collating info, maintaining threads and opening new forums when necessary, as they do for phones. But there is no one with that knowledge in charge of the Android head units section (theres not even a head unit section, its hidden in the unrelated Android Auto section), so its a mess and no one at XDA seems to show any interest in sorting it out, too busy playing with their phones or over zealously moderating threads I guess, strange really, youd have thought thered be a fair few moderators with cars (theyre hardly a niche product) as well as an interest in Android.

What for ALL the available units, not just his own type ? :eek:

It seems to me from reading his post and noting that he posted in the General forum, that he doesnt have an MTC unit, so hed have to create a new Wiki for his unit.
[Android Head-Units] cleverdicky:
Good info Guys. I never realised.

I assumed complete opposite and that everything was here, just 'burried' and lost under a ton of different sections & posts.
[Android Head-Units] typos1:
I m sure a lot of the info needed IS there, dont think "everything" is though.

And it may be buried in different sections and posts if you have a MTC unit (theres no other way of doing it, although a mod does need to keep stuff tidy, merge some threads etc).

If you have a non MTC unit then its likely in one massive thread, or spread out in random threads throughout the general forum.
[Android Head-Units] Ipse_Tase:
This has to be indeed one of the worst forums on XDA...been here for almost 10 years now and I struggle every time I need to look for something in it.

The folks offering real help are few and far between, most posts are "halp me apgrade to andriod 10" or at best "I can't be bothered to read the first post, can you make a video for me"

That kind of post is not conducive to a helpful reply.

Plus the same individuals pollute ANY thread with the same requests, without even checking if the topic is related. This makes useful information or user experiences very hard to find.

If it's any comfort, the alternative is the Russian forum over at 4pda.ru where besides the "attitude" you get recommendations to read the 1800 pages and deal with Google translate (which caused me to brick my unit...).

It doable for the determined individual to put the pieces together, but my God, what a time consuming activity.

This is why I always thank those posting tutorials (or even just their own success or failure stories), at least they contribute somehow. To the extent of my abilities and understanding, I try the same.

I doubt that anyone can sort this mess at this point, so we're stuck between lack of information, the butchered Chinese translated menus and a device that attempts to do for 100$ the same job as the 500$ ones.

/rant...I have no suggestions as to who would be crazy enough to try to sort out this sh!t :laugh:
[Android Head-Units] typos1:
By "The worst thread" I think you mean "The worst forum" ? You cant mean this little thread ? :)

4pda.ru is much, much better organised when it comes to threads on android head units.

As for sorting the mess out here, it IS doable, but as I said it would take a team of devoted, knowledgable individuals with the correct authority to do so and no one at the XDA powers that be seem to have any interest either in doing so or, as I ve said, the subject of the forums (Android head units).
[Android Head-Units] Ipse_Tase:
:o

Fixed now...

As for 4pda.ru, yes, it's my goto place for lot of things - as people have maintained the curiosity to pick things apart, fix or improve them and then put them back together. The things I've seen replacing the MCU amplifier, capacitors and LED are nothing short of amazing. At least for me.

But like I said, getting an account there (if you don't speak Russian to decipher the handwriting used for captcha) is a PITA and asking a question because your English search didn't yield Russian results is frowned upon :laugh:

I do hope that this is temporary...I can't see why car manufacturers can't incorporate fully fledged Android units (instead of the castrated versions of today) then maybe there will be less guesswork and more streamlined code..same as for the phones.

In the meantime, I hang onto my last backup really tight as somehow I managed to get (almost) everything working to my liking and I have NO desire to "apgrade to andriod 10" for ****s and giggles.

I guess most of the folks that went through this excruciating pain are in the same boat and no one wants to go back to experimenting and documenting things.

As much as I hope for a nice Wiki that would allow others to avoid the mistakes I made...I doubt it will ever happen.
[Android Head-Units] marchnz:
Great discussion, good to know there are other seniors lurking here too :)
[Android Head-Units] typos1:
Yes, those Russians are a very clever bunch, it seems that there are less on here too than there used to be, sadly. I have an account on 4pda too, there was a knack to joining which I did manage years back but after a while it asked me to sign in by responding to an email, which I never got and I tried multiple times. When I posted I used to post an English version in a spoiler as well as a Russian translation, they were always very helpful.

You dont say what head unit you have - for MTCD/E users there isnt really any "excruciating pain" to go through any more, theyve been out for so long most things are known.

If you have a non MTC unit, theres noting stopping you from documenting your experience for others by starting a wiki yourself.
[Android Head-Units] mkaaden:
Wow, never expected serious and hilarious responses in my little rant :D

Thanks guys, good to know how things work around here and good to see I'm not the only one having a hard time finding the right stuff.

Well I guess it would be a day job to setup and maintain a proper Wiki with all the information already there in the forum.

So sorry [MENTION=4974080]marchnz[/MENTION], but I already have a day job keeping me quit busy ;)

[MENTION=456516]typos1[/MENTION]

I have a MTCE unit for a MB GLK since 2017, still running Android 6.0

The unit was bought at Witson via Aliexpress.

At least I found a lot of information here on 'why' this unit does things quirky, since help from the seller always ends with no useful reply at all !

That's why I was anxiously finding a way to boot it into recovery and whack one of the custom ROM's fit for this unit to solve the quirky things.

IMHO: The products those Chinese guy's ship around the world is just a briljant alternative for those very pricey OEM in-car entertainment systems.

It is just a pity their technical support is way below standards.

If they just would collaborate with some partners in different countries, improving the product with proper feedback, they would sell a lot more units !

If I would have similar functionality fit by MB in my car it would certainly cost 10 times more than one of those Chinese units.

Well, at least you get 'premium' support, as long as you pay the bill off course.

Has anyone ever tried contacting one of those manufacturers directly to establish some sort of relation to deliver local support and feedback in return for proper technical information ?
[Android Head-Units] typos1:
I see, well youve actually got it pretty easy if you have an MTCE unit, spare a thought for the people who dont have them who really do have it hard.

The letters before "MTCE" will tell you what unit you have (as it says in the MTCB/C wiki) Witson are just a seller.

Can I ask why you posted in the General forum and not the MTCD forum then ? Had you, um, not found it ? :)

Cos if youre running 6 the info on how to upgrade to 8, 9 and 10 is relatively easy to find in one of the threads about the later versions and the threads pertaining to each custom ROM (bootable sdcard to boot into relevant recovery, another sdard or usb stick with the update on). Unless you mean Intel Sofia 6, in which case 6 is all you can have.
[Android Head-Units] mkaaden:
The unit was provided with the MTCE MX firmware.

I have already updated the MCU several times

It came from a v2.xx and is now on v3.41 which is, assumingly, the latest and greatest out there .... (wouldn't know, because there is no central page to browse them)

I know there are good rom's out there and the first thing one needs to establish is to be able to boot recovery with the stock rom.

But that is the point, none of the provided methods I could find in this forum was able to boot my unit in recovery.

It is even at a point that the power button worn out and I had to remove it from the pcb because it made the unit stuck in a bootloop.

(funny thing is that I once noticed it booting recovery, just to realize I could not operate it because the power button was stuck !!!)

Now my only option would be paying for the mod_installer or finding a (working) method to access with ADB.

The point is: I have successfully flashed tablets and phones in the past, just using the appropriate thread from this forum, but with these units ....

So hence my frustration on why it so hard to find the right information and that's why I posted it in General and apparently I triggered something ...

Nevertheless, I would love to help and supply feedback in this forum about my experience but I would like to do that in some structured form.
[Android Head-Units] typos1:
There is a specific thread for MCUs entitled "Comprehensive Updated MCU Thread". So stating "there is no central page to browse them" is incorrect. There are also two links to repositories with MCUs in, in my signature and some in [MENTION=4974080]marchnz[/MENTION]'s.

The two most popular ROMS (@Malaysk's and [MENTION=5092263]Hal9k_[/MENTION]'s) have instructions on how to boot into recovery and flash them in the first posts. If you have one of the rare units without an sdcard slot this may be slightly more difficult than usual, but you dont say. This requires either dismantling the unit and adding one (the slot is there on the mobo) or using a specific app written by [MENTION=5092263]Hal9k_[/MENTION]. Using a bootable sdcard requires a specific technique - ie ejecting the sdcard AS SOON as words appear on the screen. All this info IS available in the forum, sure some of it may take a bit of searching, but thats internet forums for you. If even all that did not work then either you are the first in 100,000s of thousands of posters to find a unit where none of the known methods works or (as it actually appears) you have a faulty unit, yet are are berating the forum for not knowing something that you were the first to find out or have a unit that is faulty. No one on the forum is psychic.

[MENTION=4974080]marchnz[/MENTION] has SEVERAL threads that tell you how to get into ADB and also how to flash via USB, there are also other threads about this too.

The fact that you posted a thread about MTCD/E units in the General forum and not in one of the (FOUR!) MTCD/E specific forums is quite bizarre, why would you not post in the specific forum for your device ? Doesnt make any sense. You were lucky that [MENTION=4974080]marchnz[/MENTION] found your post and that he mentioned me in it, otherwise no senior members would have replied. Why would you post in the general forum where there are no threads related to your device and ignore the forum dedicated to the device you require help with ? And the more you post, the more it appears that you either didnt look in the MTCD forums and/or you didnt look hard enough, so, ironically, whilst you did raise some relevant points regarding how XDA runs its Android Head Unit forums in your first post, they dont seem to actually apply to you, your situation or your unit. It seems that you simply should have started a new thread in the MTCD forum explaining your problem.
[Android Head-Units] mkaaden:
I started the thread not to seek support for my specific unit, but to raise a question about how the forum is organized and I just wondered why there are no wiki pages.

As you guys already explained how things work around here, I generally got my question answered.

But since you also asked what unit I own, I just supplied the information.

I did search the forum and read the threads from Malaysk and Hal9k.

And I tried the recovery boot options in those threads, even to the point that my power button broke.

I also read the ADB recovery threads, however I'm not fond of making hardware mods so I mostly stuck to threads that described software only.

So, please accept my humble apologies for posting my question/rant in the 'wrong' section of the forum.

Btw: I was not aware of the information you guys put in you're signature because I configured Thread Display Options to not show signatures.

It's just that all those signatures create to much clutter when scrolling a thread.

Sorry, my bad.
[Android Head-Units] cleverdicky:
Just to add my little bit to op 1st query.

After upgrading a few samsung phones over the years you do pick up a little knowledge.

For me just basic stuff like what rom to use, which kernal etc. etc.

While spending time in the work van talking to my boss about phones once, and what I had done over the weekend to upgrade mine, he was well impressed and thought I was really clever.

I did say to him the truth is, I am certainly not clever.

I read about the experiences and work of others and just copy.

The clever people are the ones who understand, write and develop all this stuff.

Moral is, never take anything or the work of others for granted.
[Android Head-Units] wouterverboom:
Hi there,

After doing an upgrade my unit it stuck with a black screen and need to get into recovery mode in order to reload a working firmware.

Anyone any idea how to get there?

Tried the reset button for some time with and without home or on/off button and also removed the power source and pressed reset while putting power back but nothing seems to work :(

So i'm stuck for now :crying:

Any help?
[Android Head-Units] Kjricker:
Did you ever get your unit fixed? Did you try restarting with a USB plugged in with the firmware file on it?
[Android Head-Units] wouterverboom:
No sorry... never got it working again. Had to send it back for a replacement unit.
[Android Head-Units] Kjricker:
I've been doing a lot of back and forth with their support on another issue and I've updated my MCU and software so many times now I thought maybe I'd be able to give you a hand.

Do you use any navigation apps on your Avant4? When I use ones that have voice navigation, the voice is getting truncated at the start and end of the directions. Some apps more than others and it seems to be related to those apps that use TTS (Text to Speech).
[Android Head-Units] wouterverboom:
I'm using Waze via Android Auto. So i'm not having this problem.
[Android Head-Units] Kjricker:
So it runs from your phone and just displays on the Avant4? I have Waze running on the unit directly and it gets truncated.
[Android Head-Units] wouterverboom:
I have al running on my phone and use a Android Auto box.

U can buy it from Avin USA. See website for all options on your Avant4.
[Android Head-Units] wjdones:
If you hold the volume knob until it starts blinking then let go and hold it down again it will boot the unit into recovery mode.
[Lenovo K6 / K6 Power / K6 Note Questions & Answers] MrSquaare:
Hello,

I tried to install LineageOS 16.0 by following the instructions carefully

Unfortunately, when the phone is restarted, it will block for several minutes (more than 20 minutes) on the startup screen.

So I tried to reboot it, but I couldn't.

Here are the different manipulations I've tried:

- Press the POWER button for a long time (more than 10 seconds, more than 20 seconds, more than one minute).

- Press the POWER and VOLUME UP buttons for a long time (more than 10 seconds, more than 20 seconds, more than one minute).

- Press and hold the POWER and VOLUME DOWN buttons (more than 10 seconds, more than 20 seconds, more than one minute).

- Press and hold down the POWER, VOLUME UP and VOLUME DOWN buttons for a long time (more than 10 seconds, more than 20 seconds, more than one minute).

None of these manipulations worked.

Has anyone else encountered the same problem?

Thank you,

Sincerely

Nope it doesnt. Mine is RMX2071, chinese version. I dont know if the global/european or indian version works.

That's just one reason I never buy the Chinese versions, ever. There are just too many issues with those models across the board.

I am looking at the Global version, the European version is single sim and I need dual sim. Plus come Jan. 2021 all devices on T Mobile's network must have VoLTE or else they will be restricting the device from working on their system.

[OnePlus 7 Pro Questions & Answers] vebulous:
Hello, i was recently made aware that my usb 360 panoramic camera module (Lolly360) does not work in android 10 due to a bug in the source of Android 10 that lacks the proper permissions for devices that use USB video device class (UVC) api's. I'm not 100% how things work, but I think an api in the SDK28 (USBCamera-target-API-28.apk) is bugged but maybe has been fixed in the latest Android 10 source. Unfortunately, im not sure if it exists in OxygenOS 10.3.3.

Is anyone aware of this? And/or does anyone know where i could begin to tackle this issue?

I posted in the OnePlus community forums, but i feel like it may have fallen on deaf eyes

[Huawei P Smart Questions & Answers] SingingPotato:
Hello,

I am the owner of an unlocked P Smart 2018 running PhHusson's generic ROM, thank to his work.

This ROM was based on android 8.1, and required EMUI 8.

I am thinking about moving to a more recent version (PhHusson's, or Haki's AOSP 10 if they are not the same), but it would need me to upgrade EMUI from 8 to 9.1.

I have two questions about that:

1/ does it worth the pain ? (driver optimizations, better security, more recent apps ?)

2/ if yes, would the upgrade from EMUI 8 to 9.1 lock the device, or block/complicate the flashing of custom ROMs ?

I was not confident the first time I flashed my phone, additional difficulties would be a con- argument.

Thank for your interest,

[Huawei P20 Pro Questions & Answers] dantahoua:
Hello!

My son found a P20 Pro CLT-L04 4 month ago (Canada). The phone is FRP protected. I tried everything but I can't reset the phone. If I understand well, I have to downgrade the firmware. So I downloaded the CLT-L04_default_ca (Charlotte 8.1.0.152), plugged a hardrive on the USB-C to USB adapter. I always ended up after 1 minute to the "Software Install Failed". Seems the phone read well the hard drive as I ear it spinning (it has his own power supply) and scratching, so something happen.

Any idea? Should I try another firmware.

I have on my HD: "dload->CLT-L04_default_ca->update_sd_CLT-L04_default_ca.zip"

There is also a update_sd.zip file in the dload folder.

Multi-Tool told me: CLT-L04 9.1.0.365 (C792E9R1P11).

I cannot believe I will have to throw this phone into the garbage just because of a lock!

If someone could help me, would be really appreciated.
