Fabio, I am thinking of rooting my center, it is all covered, I can't use floating widgets for example, did you do it for a similar reason or another? will it be worth it?

Fabio, estou pensando em fazer root na minha central, ela é toda capada, não consigo usar widgets flutuantes por exemplo, tu fez por motivo semelhante ou outro? será se vale a pena?

Hi all.

I'm locked when i try to put comand "adb shell" or "adb root" (i looking the video to help but not exactly same how to)

No audio control

Hi all, I hope everyone is well in this current craziness!!

I recently purchased an android stereo as a birthday gift for my dad. Marked up on Ebay as running Android 9.1 alas Aida64 confirms it is in fact 6.0 Marshmallow and the 8227L-demo.

I've tried everything to root it with no joy.

I've also tried every combination to force to bootloader as I have an update firmware ready on usb, again no joy.

The reason I have been trying the above is I have no control over face, balance or any of the equalizer settings!!! So just flat sound output.

Has anyone experienced this and or found a solution???

I'm not getting much from the vendor at the moment, and if i can resolve this issue then I'd be happy to not return it as it runs pretty well other than the above issue.

Any advice is most welcome.

In my case I put it for memory, only 1GB, with the root I was able to install a swap app that gave a considerable improvement, although it is still very slow, especially at startup.

No meu caso eu coloquei por questão da memoria, apenas 1GB, com o root pude instalar um app de swap que deu uma melhorada considerável, embora ainda seja bem lento, principalmente na inicialização.
[Android Head-Units] Baronmic:
I did this.

I messed up the touch screen. Which I managed to make right again. Audio has completely stopped. It will play files but no sound. The Wi-Fi does not like connecting to anything. Couldn't connect to pc as could find a driver. The 2 usb ports don't seem to do anything on boot but both work. Even with usb debug.

How do I fix this?
[Android Head-Units] pietrek38:
A connection could not be established because the target computer is actively refusin

I have a problem with connection, Can you use adb via USB? Does anyone have drivers for the USB head unit to make the laptop detect it? Which usb connector to use for debugging? What should the commands on the command line be? Can anyone help? I will provide new firmware for YT9213A_00009_V001_20200523
[Android Head-Units] gamalulu:
i want to solve this problem too. every time we restart the machine and i don't like to wait - has anyone found a solution
[Android Head-Units] Doubletop12:
Unfortunatley if you have a head that is 8227L_demo it can't be fixed. It shouldn't happen, I have 2 other units and, unless you've not used them for a long time, they start up straight away.

Just buy something different. Plenty to choose from, direct from manufacturer, on Ali_Express rather than the factory rejects on Ebay
[Android Head-Units] gamalulu:
I didn't quite understand what you meant.

i meant that my radio starts cold every time and that always takes a long time. can't i put the radio to sleep? i couldn't find anything in the settings.
[Android Head-Units] Doubletop12:
There is no standby power circuit to keep the set ready for the next time it is switched on so everytime you start the vehicle the system does cold start and re-boots. Other units have the standby power circuitry, maybe a large capacitor. If the unit is not switched on for some time the capacitor can discharge and the unit re-boots,cold start. If you use the unit frequently it will start almost immeadiatly with the settings it had when you switched it off, warm start.

The 8227L_demo doesn't have this feature.
[Android Head-Units] gamalulu:
For me the problem is when I pull the key the radio shuts down completely. And every time. When I turn on the ignition, the device reboots. And that's annoying. My friend also has the same device. When he switches on the ignition, the radio is ready for use immediately. There is no cold start. Are the power cables connected differently? Or is it a setting thing in the menu? But I couldn't find anything in the menu.
[Android Head-Units] JoaoNascimento:
Maybe you have connected the red and yellow cables togheter from the HU to the 12v from the key.
[Android Head-Units] gamalulu:
there are 3 cables for the power supply. Red 12 V+ Black ground and yellow 12v+ key
[Android Head-Units] JoaoNascimento:
Black must go to the black in the car (negative 12v or ground).

The red must go to a permanent +12V In the car. Check with a multimeter for a permanent 12V in the car. One that stays even when the key is out.

The yellow must go to a +12V that exists only when the key is turned (normally the first position of the key).

Your problem is consistent to a cenario where both red and yellow of the radio are connected to the switched +12V in the car.

Check this first before searching for problems in the unit.

[Android Head-Units] ExtremeMOD:
Hi guys,

I'm a hobbyist head units modder and luckily do speak Russian do 4pda forums have helped me to learn what I know today.

The short answer is - you can't root your Android unless it's MCU starts with YT92..... The only way to root anything else is custom code unless you can find someone who uploaded a modified system update specific to your hardware.
[Android Head-Units] ExtremeMOD:
Sorry but you can't do much with your unit.
[Android Head-Units] CruzeRSLT:
Iceblue, any way I can change the Km to MPH and climate controls to Farenheight? I bought this used for a very cheap price. Compared to my other unit the sound on this is night and day better than the newer unit. The newer unit has a setting for you to change KM to MPH and Celsius to Farenheight. Here is my firmware. I also noticed it's got a Serial number. It seems if you press and hold the model number you can make a serial number. As I was trying to get into extra settings as Phoenix Auto video shows.

Hope you're still around here.

Where did you get the password to get into superuser mode from? When I try doing that, it gives me "system/bin/sh: su: not found"

Did you have any issue like that? Any workaround?
[Android Head-Units] rosrus57:
Hello, dear dougdude10 ...!

I will be very grateful if you explain to me where to find the GRANT command when opening the SuperSU application apk (SuperSU apk)
[Android Head-Units] rosrus57:
It looks like this will only happen when I perform the previous steps outlined in your comment ...
[Android Head-Units] bajgainp:
I don't think he's around.

Were you able to execute all adb commands to root your device? This method isn't working for me - I can't get into superuser mode through adb. When I do "su", I get "system/bin/sh su not found"
[Android Head-Units] rosrus57:
In a few days I will try to eradicate it and if it happens at all I will describe it here, but now there is something that will interest you...

For anyone interested in the "Engineering test debugging" password after logging in, through the four eights...

It's no longer a secret - here she is:

26959910

From the menu there you could change the option for the stereo the system so that when the car is turned off, it not only stays stopped, but also turns off completely.
[Android Head-Units] pbmurdoc:
I have a Eonon GA9450b. I was able to get root but before connecting I had to enable developer mode, and turn on USB debugging. Once that was completed I was able to follow dougdude10's instructions.

I'll also add that instead of using google drive to transfer the supersu apk I just sideloaded it through the abd connection which for me was easier and faster.
[Android Head-Units] ultradj83:
How did you enable USB debug?

Regards
[Android Head-Units] pbmurdoc:
USB debugging is a setting that you can enable in developer options once you have enabled developer mode.
[Android Head-Units] ultradj83:
Ok I think you enabled debug by tapping 7 times on build number, correct?

I'm on Eonon device, too.

They come from factory with supersu executablt (maybe they use this for some customization), but user has no permissions to execute it.

By the way, this prevents some apps from installing or running (mainly DRM contents apps like Netflix ans so on).

My original idea was to install supersu and use it to pass to magisk in order to use magisk hide and fix apps problems.

Do you think this is feasible?

Regards
[Android Head-Units] pbmurdoc:
I was able to install the supersu app and it works. I haven't tried installing magisk yet.
[Android Head-Units] ultradj83:
Do you know if the supersu installation you completed has overwritten the original supersu executable?
[Android Head-Units] pbmurdoc:
No idea.

Just wanted to come here and say I'm getting the exact same issue. Currently not able to figure out a solution. Pretty sure that SU is installed by SuperSU, but then, you need to be rooted to install that i'm pretty sure??
[Android Head-Units] ashensii:
I had SuperSu running with root access but then I "Removed SuperSu for another root app" from supersu settings. Now when I try to root again with supersu, I don't manage to get "su @#zxcvbnmasdfghjklqwertyuiop1234567890,. " command working in shell, it doesn't change state to superuser. Has my passphrase changed and what would it be?

[Android Head-Units] tyrell.harrell:
Would you like to root your any Android platform device?

According to my experience, Kingroot one-touch root apk is the most suitable solution. Kingroot has the most successful rate for various types of Android devices except Android phones and Tabs also. However, better you should use an Official file for your rooting process. Eles you have to face some issues while the rooting process. Kingroot official website is helping to contact the developer's support team for any issue. Thank you!

Hi, why does terminal emulator crashes every time ?
[LeEco Le Pro3 Questions & Answers] TheOkMan:
So I've finally mustered up some courage to flash something fancy into my X720, and this is what happened. Up until flashing the ROM itself ([ROM] [TREBLE] [8.1] [Official] AICP 13.1 (Pro3 aka zl1, zl0, X727,X720,X722) by mosimchah) it went relatively well, but then I got twrp error 7. After some tweaking error message changed to "failed to mount '/system' (invalid argument). Can it be because I've wiped "system" before flashing? I think instructions said to do so... Anyway now I'm stuck, because even though I made a twrp backup, I was smart enough to remove it from the phone and now I can't put it back, because one of the files is 4gb in size, and I get error message when trying to copy it to phone storage (file system indicates "generic" or something along those lines). I'm new with this kind of stuff, so I really could use some advice. Should I flash stock rom? If so, which version? I can't remember exactly which was mine. I wonder if there's something to be done with that 4gb recovery file? And how did twrp mess up like that? Shouldn't it be calculated more carefully?
[LeEco Le Pro3 Questions & Answers] clsA:
You can use a SD card or a USB otg and a flash drive for your backup
[LeEco Le Pro3 Questions & Answers] TheOkMan:
Thanks for the tip, clsA. Gave me quite a push. However, here what happened next: with USB OTG I was able to move the missing 4gb file to the phone storage and recovered my phone to a fully working state (wasn't able to recover directly from USB - anyone knows why? Maybe because it's ntfs?). Thinking I've established a good pivoting point I proceeded flashing custom ROMs. First time I did everything the same. The result was same, obviously. Then recovery. Then I tried leaving *system* out of wiping process and switched my ROM from AICP to DotOS. Installation went through without errors, but the ROM wasn't working correctly. SIM card wasn't recognized, HOME and DETAILS capacitive buttons wasn't working, couldn't download apps from play store, some crashing here and there. I though I had enough, and decided to recover for the time being, but when I did that upon boot up I got *ENCRYPTION UNSUCCESSFUL* error. There's restore system option under it, but it doesn't help. Tried recovering again - same. Reflashed DotOS - got my SIM recognized, but all other bugs remained. I think I'm doing something wrong when flashing, but can't figure out what. There isn't that many steps, and I followed them through... Even tried removing first lines of that script file (in ROM zip file) to get rid of that error 7 at the beginning of AICP installation, which didn't do anything (there's also a chance I've deleted wrong lines, or not all of them..). Maybe someone had similar problems and could share some ideas? And that Encryption error is very strange. Nothing changed after first recovery, so why I'm getting it? All the directories are in ex4 format. Any thoughts about this one?

Thanks again, clsA. Looks like this could be it. Will try it soon. For now I have flashed [ROM][X72X][7.1.X][OFFICIAL] LineageOS 14.1 (which is now 8.1 somehow...) and it works without any issues so far.

Any insights on why I'm getting *Encryption unsuccessful* error after restoring my original system image via TWRP (first recovery was fluent, error appeared following my later attempts for recovery)?
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] diehardbattery:
Apologies in advance if this is not the right place for this. Please move it to the appropriate thread/forum if needed. Thank you.

I've been working on a way to have DeX launch when my bluetooth keyboard is connected. I have shared my flow with the Automate Community. Any feedback or suggestions are welcome. I'm pretty new at this, so go easy on me lol.
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] aspexil:
Whenever anyone asks about automating tasks on Android I always think of Tasker. I haven't used it on the Tab S4 yet so do not know if it can manipulate the DeX setting or not. Might try and see what the Tasker community says. That would certainly be handy to have it change over whenever the bluetooth keyboard or mouse are connected. If you find anything out be sure to post the solution here so we can thank you for the work.
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] diehardbattery:
I have been in touch with the Tasker community, and so far it's not looking promising.
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] dr460nf1r3:
Works pretty well thanks !
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] sandibhatt:
Awesome man... Works well. Definitely not the right forum to ask this but is it possible to create a flow to toggle Wi-Fi Calling on or off based on which Wi-Fi network its conn to or GPS? I searched but couldn't find anything for Tasker or Automate.
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] berkovich-98:
Finaly i find a way to toggle dex with Tasker but you need certain apps. QuickShortcutMaker and IntentTask(plugin for tasker).

First open QuickShortcutMaker to find Samsung Dex on activity selection. Then tap the ModeToggleActivity then add it to favorites(star icon) to find it later.

Now open Tasker and creat an action. Add action with IntentTask in plugins and select the Launch shortcut. Then in the name section press the pen icon and choose activities. Now tap on the favorites and tap Samsung DeX and create. Then tap done go back and you are done.
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] [Lemmy]:
...brilliant.

edit: needs more hacking. I have a Samsung s5e and a foldable bluetooth keyboard. with this tasker setup I start dex whenever that keyboard pairs with my tablet which happens when I open it.

when I close it, nothing happens, and when I open it again, tasker switches back to normal tablet mode - needs some kind of "only when not in dex" trigger or something.
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] edmondt:
Perhaps there is a command line option we can use in Tasker on Bluetooth connect?

Reference: https://developer.samsung.com/samsung-dex/testing
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] berkovich-98:
actualy it is weird to not back normal when close it or maybe i can just add an exit task with same action to close it (and maybe it is the way that because bluetooth profile is just do the action when connected something and do a different thing on disconnected sorry i am away from my tablet)

btw intenttask has a state condition with see the current app (samsung dex an example) to set a variable action maybe to prevent force close dex
[Samsung Galaxy Tab S4 Themes, Apps, and Mods] [Lemmy]:
where / how do i configure intenttask with that state condition?

Maybe this is a really dumb question,

but i have this problem with longer movies, say 50 movies. If i watch them on my phone they hang and lag terribly! i dont know what the problem is... short movies arent the problem! plz help :)
[HTC Vox] prajith:
which player do u use?

try tcpmp.

i watch much longer movies using that and no lag.
[HTC Vox] cpt.bert:
tried tmcp but same result! could it be that my memory card is too slow?
[HTC Vox] Da9L:
maybe the video you are watching is too big to handle for the vox's cpu ? if thats the case.. then use PocketDivXEncoder to scale down the file and qulity, which you can't see on the phone.. This allways works and you won't have any lag at all .. ! Try it, its free.. :) Not only that but your video files will get much smaller in size!
[HTC Vox] frauhottelmann:
It usually is a memory problem. You should reencode them to lower bitrates and/or resolution and use a codec that doesn't need much processing power!

EDIT: Ups you were faster!
[HTC Vox] Da9L:
Hehe well then it just got confirmed.. :)

But my suggestion would be that you use TCMP and then encode your videoes with PocketDivXEncoder.. It encodes the movies in divx format which TCPMP supports fully..
[HTC Vox] prabhatnath:
Good TIPS Friends... I convert all movies to MP4 format and plau using my default 710 (Windows Media Player). No issue for me. I will also have a try of TCPMP player and compare it :) Hope this will be much light for phone memory :)
