No sound from speakers

Recently I posted about my 7501 not having any Bluetooth audio.Two trips to HTC finally got that fixed. Now I have the reverse problem. I only have Bluetooth audio. Nothing from the speakers. This started intermittently at first & now there's nothing. I use Bluetooth a lot & it acts as if it's just not switching the speakers back on after I've used bluetooth. I've tried turning the mute/unmute on & off numerous times as well as doing the same with the bluetooth, plus several soft resets & battery removal & reinstalls, nothing. Any ideas? I really don't want to send it off again for repairs or even do a hard reset if possible......Thanks.

this happened to me like last year. however, i didn't have the previous troubles you had. what happened was my unit was bonded to my headset. a call came through and the next thing you know all the sounds were being streamed to the headset only. after unbonding, deleting the connection, resets, removing the battery, etc....nothing changed. i had to do a hard reset...that worked but after like 3 calls all the sounds would stream back to the headset only. the speakers refused to work.
i don't know if this fix is applicable for you. what rom version are you using? is it the original? what i did was upgraded my rom to aku3. my unit was using the original rom when the problem happened. i was reading a lot on the aku3 rom but was hesitant to upgrade. let's face it, everyone who upgrades is always in danger of bricking their units. but in my case, i had nothing to lose....if upgrading my unit did brick it...then i wouldn't feel as bad given the problems i had regarding the bt / non-working speakers.
thankfully the upgrade proved to be successful and it certainly fixed the issue i had. to date i've had no other problems ever since i upgraded to aku3....which is another reason why i'm now hesitant to upgrade to the 4.0 rom. my unit's functioning in tip-top shape and i don't really see the need for the upgrade.
for you, if your unit is on warranty then i would suggest that you send it back to the shop. if all else fails, then perhaps you may start considering the rom upgrade. a friend of mine had the same issue and he mentioned that the feedback from the shop was that his rom was corrupted. thus, he did the upgrade as well and that fixed the problem.
cheers

In the Universal thread, I've come across that problem of yours. The solution was plugging in a wired headset or headphones, then just unplugged it again. This usually brings back the sound to the speakers. I believe the problem lies in the headphone jack and had to be replaced. I don't know if it is similar to what you are experiencing, but it won't hurt to try.
Good luck.

US-JY-UL135N2 crashing and won’t recover for hours.

Hi all
the text below is an email exchange between me and joying support. Besides the obvious language barrier I also don't think they are willing or able to do much troubleshooting. I was wondering if anyone here would be kind enough to point me to the right direction.
The problem basically has started after two or three unsuccessful root attempts that most likely left some script that I cannot erase with a factory reset. It could also be one of those very unlucky coincidences where the problem appeared then but rooting was not the cause.
It looks like the unit powers up normally after a period of complete inactivity that has to last at least a few hours and then everything is normal for about one hour. Then it shuts itself off again but will not restart for a few hrs. i didn't get a chance to troubleshoot further and provide detailed timing but I don't think its a heat issue as described elsewhere
After I rooted it successfully I installed the "joying extra tools" but was not really able to use the app.
any help would be appreciated
thanks
Hi I just installed my US-JY-UL135N2 a few weeks ago. It was working fine for a few days but had the same problems described in various posts.
I tried to install superSU in order to install a complete backup application (titanium backup) following the directions from this forum (cant post link yet) first couple of times I was unsuccessful (could not get permission to write the files). After that it started rebooting at random times and sometimes it wont wake up for a few hrs. A couples of days later I rebooted the unit and tried again to root and this it worked. The crashes did not stop so I did a factory reset from the settings menu. When that was completed I looked at the applications and superSU was still there and the crashes continue. I think that maybe some incomplete files have remained when I tried to root the first time. What else can I do? If I did a factory reset shouldn’t it wipe everything? Also should I upgrade from 5.1.1 to 6.0? how? Will that solve the problem?
Do you have support in the USA? Can I talk to someone here?
Dear friend,
Thanks for your email .
Do you mean that the head unit will be crashed after you download the backup application ?
we think that maybe the application is not much more compatible with our head unit .
could you try to directly unload the SuperSu app ? and then check whether it will still crashed ?
and could you show a video to us how it crash ? so that we can know more ?
Hope your positive reply and then we will help you .
Thanks
candy
Thanks
Candy
No I never got a chance to install the application. The unit is now dead it does not start at all so there is noting to show. Is there is a way to make it start? If there is I can uninstall the superSu and let you know if it helped but for now I can't do anything
Dear friend,
Thanks for your reply .
please noted :
You said that you have not installed the application , so how your head unit go dead ? we are a little confusing .
could you please explain what you have done before then the head unit go dead ?
because you also said the Supersu is there , if you have not installed it successfully , bow it will be there .
we hope your kindly reply then we can know that how to help you .
I Said I did not install the backup application (titanium backup) but i did install superSu.
I tried to root the unit but failed a couple of times. The third time I rooted it but then It started random crashes and reboots so I didn't get the chance to install anything else. Can you just tell me if there is a way to restart it or do I have to send it back for warranty repair?
hope you can have a try and feedback us .

Hi
The unit came back on today by itself after about 15 hours. I uninstalled superSU and reset it again. I don’t know if its going to be stable this time but I will let you know in a few hours
The update you’re suggesting is 6.01 and I read that there is problems with it. Isn’t it better to stay with 5.1.1?
Where can I find the latest file for 5.1.1?

Hope your try .
Thanks
Candy
Ok so I left the car off for a few hours and just tried it again. I turned the car on and the unit DID NOT TURN ON AGAIN. It just wakes up whenever it feels like it.
I can’t do anything to it until it turns on again. I there a way to reset it completely?
here is the blog on how to update the android 6.0 : sorry cant post links yet
(please update to 2017-7-7 )
you update the head unit according to the blog , then it will occurred the recovery interface .
Hope you can try .
Thanks
Candy
How do I make it enter recovery?
-------- Original message --------
Ok I just I did the update 2 hrs ago. Then I drove for about 40 minutes and shut off the car. Went back 20 minutes later and tried it and it turned on without problem. I just tried it again now and it won’t turn on. I don’t know what else to do at this point. Is there a way to get logs when it turns back on? It usually turns back on after 6-7 hours

Dear friend,

additional observations/thoughts
I just noticed something else. When I start the car in the morning to go to work the headunit is always on immediately. Does this mean that it stays on after it restarts itself at some point at night ? or does it boot up that fast? (less than a second)? I dont remember ......if this is a heat issue and it started at the same time as when I was trying to root it wouldn't that issue kind of go away when I installed 6.0.1? its supposed to have better cpu management right?

In my opinion it's the heat that's causing the problems combined with with the fact that maybe some of the electronics gave out. It returns back to life when it's cool enough.
Either way make a video demonstrating the issue, complain and demand a new unit under warranty.
In the meantime you can install an app that can monitor the CPU temperatures
Like :
1. https://play.google.com/store/apps/details?id=info.kfsoft.android.MemoryIndicator
2. https://play.google.com/store/apps/details?id=com.yanyan.cputemp
That can display the temperature at all times no matter the app that you are in
Use this app to test the stability and temperature under heavy CPU load : https://play.google.com/store/apps/details?id=com.into.stability
Check the temperature it reaches before blacking out.... it could be the CPU giving out on high temps or maybe something else... just a thought...

Thank you for your reply I will try to work around its schedule and do that. I just went and disconnected the power completely so it stays cool until I'm able to work on your suggestion. Hopefully after work it will start up normally and I can sit there for an hr looking at the temperatures (not happy bout that for a brand new unit) .
the funny thing is that it gives out when the car is off so the unit should be on sleep. How can the temps go up high enough to shut it off when its not even doing anything? The dormancy setting is on so I was assuming it went to sleep.
here is the reply i got from joying below. Basically suggesting to do what I have already done to it
Also some people suggesting sending them a video but a video of what? when its on its running ok when its off its off for hrs and when it comes back its normal again.....it would be a veeeery boring video
Dear friend,
Thanks for your well-cooperated with us together .
please noted :
1) we think that the files on the head unit maybe mess after your root the head unit .
2) So now the head unit can not turn on again , and it may turn back on after 6-7 hours ?
3) if yes , please try to do following processes and check whether will be workable for your problems :
1. Download the update file from window syetem computer, then upzip it and copy the files into
SD card without any folder. Then please insert the SD card into GPS maps card slot.
The files also will be the same updated file :
2. Put ACC wire(red one) and BATT wire(yellow one) together, then connect it to positive power supply 12V;
Put GND wire(black one) to GND.
3. Turn on the head unit,it stuck on JOYING logo, please click "reset"( first time).
4. After the first time reset, the item will restart and it stuck on JOYING logo, please click" reset"(second time)
5. After the second time reset, the item will reboot and it stuck on JOYING logo, please click " reset"(third time)
6. After the third time reset, please don't power off the head unit and wait for a while to update the head unit.
Then watch this video to learn how to update the system: xxxxxxxxxxx
Please check whether it can appear the "Joying logo " and go on the processes we suggested .
Thanks for your time

Oh man... you made a big error telling them that you rooted the unit... rooting had nothing to do with the behavior at hand but it's enough to give them something to talk about and delaying to delivering a new unit.
What you should have done before telling them you have a warranty problem.
1. Start the default Joying File Manager go to the internal storage, select all, delete
2. Take out all the SD card and USB sticks and DON'T put them back
3. Reset the unit to defaults, that does not remove root but removes all the apps and settings
4. if the unit is still unstable and it seems related to heat... wait till it cools down
5. prepare a stick with the firmware that you have already on the unit for a reflash
6. flash the unit - now the root is gone - everything is back the way it was when you bought the unit
7. test for stability... if you still have issues that means it's not software it's hardware.... warranty time.

Thanks a lot man!
You have no idea how many times I searched for a way to restore back and wipe all data because I could still see the garbage in there even after a factory reset but couldn't find out how to.
I will follow your steps and then call it a day because it would have to be a heat issue at that point
I ts funny though that it didn't show up prior to root.
On the rooting issue now. I thought they provide a link on "how to root" on their blog....I didn't think I was doing something wrong by just rooting it. I didn't really get a chance to use the root access anyway! You would think they would provide a way to do a full back up in case something went wrong this way we didn't have to resort to rooting
thanks again. I will update the post when I have news

BTW does anyone know what temp the CPU should be running at? or whats the max before it shuts down?

Search!
The past weeks have been full of this in 2 threads: the upgrade thrad and the heatsink thread.
And edit, who also answered you in this post, added even more on this in his Q&A thread, which you obviously also missed.

Update .....and some thoughts
@ surfer63. Point taken....I realize I was been lazy. Please accept my sincere apology for taking all the work you guys do for granted.
I don't have much to contribute but here is an update on my issue and also some thoughts on what to do in order to be able to enjoy the best of both worlds _Reliability and function_ in a car radio experience.
BTW. I ripped out my very expensive but very restrictive factory rocford fosgate navigation/camera/Bluetooth/overhead console/back up sensor/ infrared headphone ..blah, blah, blah system in order to install this one, so I had high hopes that I could get this to at least function somewhat reliably but I've been driving for two weeks without a radio or Bluetooth for my phone.
anyway...
Joying USA finally came through with a solution. They offered to send me a 6021 to replace my most likely burned out 5009 unit _new one is on the way_
I had to pay shipping and I was charged $300.00 for the unit but I will be refunded $200.00 when I send the other one back. I'm happy that at least I will have a radio again and have learned my lesson about how real a Chinese warranty is. I hope I wont have any problems getting my $200.00 refund ( I have only used the old radio for about 2 weeks before it burned out)
I chose to "upgrade" to the 6021 _ It would be the same cost for either unit _ because I was told it is more stable after the re-design of the main board and the LCD board. I'm hoping that the overheating issue will be less of a problem with this one although I read reports to the contrary....
I also took surfer63's advise and read up a little and I now know that there is no way to rely on a Chinese android unit to replace a factory head-unit or even a brand name one for that matter because the stability is not there yet (my opinion). We should probably be thankful though that at least Joying and others are not afraid to try and provide this alternative.
I also read up on all the newest high end brand name head-units and nothing has changed since last time I looked. They are all crippled, restrictive and proprietary for the most part when it comes to peripherals. They offer really good sound quality but the ones with the most features also suffer from software and hardware glitches though less frequent than the Chinese ones. The Chinese android units do offer a glimpse into the future but my experience is that they are not at all reliable or fully functional. I believe that in a car environment the most important functions are ease of use, radio reception and phone/Bluetooth quality and reliability (terrestrial radio is still more reliable than internet radio for people that want to listen to the news or traffic updates or local events and such...) . Once that's covered then I guess sound quality, internet connectivity for online content, online navigation and voice commands as well as other similar features become important.
I don't think there is one single head-unit out there that covers all that but maybe not all hope is lost.
My solution is to purchase a single din head-unit with a reliable radio, good sound quality, stellar quality hands-free phone Bluetooth function and maybe USB phone connectivity. I have a spare space in my console so I will install that in there and install the Joying unit _or the next android experiment_on the double din space above. If space is not available on the console one could probably hide it in the glove-box or under the dash.
when the Joying dies again _notice I wrote "when" not if... I can revert back to the simple one until I replace it with the next upgrade or maybe with a tablet. They now make some nice built in mounts for them https://soundmanca.com/
I haven't had time to research the single din unit yet but it most likely will be one of the major brands. maybe this one https://www.amazon.com/Pioneer-DEH-...ud-20&linkId=644693c89a21ea33f675e3023ce5cc4b
I will try to figure out a way to make them both work through the same amplifier and be able to use the hands free function on the single din one, navigation and backup camera on the android and have the choice to play music from either one. I'm not sure how to do that yet but looking into it now. Maybe I can use the Aux input or another "source" input on the single din one which could also be wired to the factory steering wheel controls so that when I answer the phone the AUX switches off and the hands free takes over. I think when the phone call ends it would have to switch back to AUX . I will try to update this post when I figure this out and in the mean time I welcome any thoughts or suggestions
Thank you all for your support

A-sure L2ovb Head unit crashed and wont reset. Any roms to insert to SD slot?

Hi guys, im going round the bend with my Vauxhall head unit from A-sure, the number on top starts L2OVBR.
I have seen a few posts about upgrading by sd for the S3 models of these same units, but none for my type.
I tried the S3 rom and it trys to load but i get error message about files being missing
INFO: CANT FIND MCU FILE
INFO:CANT FIND STM32VD.BIN
DVD:INFO: CANT FIND B288ROM
INFO:NAND ID EC F1 00 95 41 EC
This is the info i get when attempting to load the S3 rom. I assume the s3 and the L2 are not compatable?
What happened was while playing from usb the usb came loose and turned off, the unit then went blank.
Now when i press the reset with a pin, the car logo will give a quick flash then cut out. I have tried holding pin in for 2 min, tried combination of buttons but still the same.
Any help hould be great, If anyone could link me to the rom i need that would be great, As it does try to load the rom but i cant get the right one. A-sure dont respond to Ebay or facebook or Email.
Thanks for taking your time to read and i hope you can help me.

Nobody?

wince 7?
Looks like these units are loaded with Wince 7, I have emailed A-sure but no answer as of yet, im not surprised as all over the internet it is reported they aint interested, and when they do they want you to return the unit to china!
I have been looking all over the internet for the files i would need to repair the software but cant find a thing.
I downloaded a file called 117-nav-en-wince6 that was reported to help restore windows on these units but nothing with mine, just a blank screen until you press the reset button and then you would get a quick flash of the vauxhall icon and then goes black again.
Im wondering if something has fried inside the unit? but then it does try to load the wrong android files as it should, and the picture comes up when pressing reset so would imply the graphics chip is ok?
Nobody got any ideas at all?

ran 12v to the unit and canbus connection to rule out the canbus but it still does the same with the canbus box disconnected.
so def a problem with the unit. Am i alone in the forum? lol

Fixed the unit by restoring the software. I now have the software for the L2 and L4 A-sure models
just incase somebody else runs into the same problem, and gets about as much help as i did.
Least its fixed.

same problem

Xtrons PX5 PBX79ATT suddenly loses all BT

I'm a long-time programmer, but this is not a programming question, and I'm not even sure that this is the right place to ask this question. If not, my apologies. I cannot find any real Xtrons support anywhere on the web. I have emailed them, but have not received a response, and I'm impatient.
I purchased and installed an Xtrons head unit, and it worked OK for a few weeks. This morning I went to breakfast and was able to play music through BT into the head unit. After breakfast, all of my BT pairs were gone, and when I scanned to see local BT devices, the scan never terminated: it went on forever. Attempts to pair to the head unit from my phone failed. BT is suddenly totally dead. I've power cycled the head unit (turned the car off and on) repeatedly.
Not sure if this is a driver, software (OS), or hardware issue. Not sure if there is a BT antenna that could have been shaken loose. I can't see any way to force the Android device (the head unit) to do a normal power down as one would with a phone or tablet: the "power" switch seems more like a "sleep" switch. There are two BT-related processes, which I can see, one of which I can force to terminate, the other of which I cannot, but that has not helped. I cannot see any way to clear the cache or data for these processes. I'm looking for some kind of "reset", without joy.
Any hints would be appreciated. Assume that I'm somewhat experienced at Android use, but not at Android development.
Thanks
Jon
Edit: I stumbled upon the hidden location of the Reset button. Once I reset the unit, the BT functions returned immediately. There documentation does not include a photo of the front of the unit, so finding the Reset button was not obvious. And many emails and an hour on a chat session did not have Xtrons support suggest a Reset. Anyway. It's working again.

Witson PX5 RVF 4+64 "alive" just for a few seconds...

Hello ,
I would be very happy if anyone has a solution for my problem. Having spent a long time for search in this forum I even could not get an idea for a solution.
After a good first experience with a WinCE S100 I ordered a Witson PX5 RVF 4+64 for my Opel Astra J via AliExpress.
After the - very probably absolutely correct - installation a start screen was shown very briefly. Then the touch screen stayed black and still is. From Aliexpress I got only confusing information from China. a.) A rar file with an image.rar, which is used to boot from an SD-Mini-Card. b.) Videos showing a completely different approach using DriverAssistant 4.5 and Factory Tool 1.45e.
If I connect the (removed) radio to a 12 Volt laboratory power supply (ignition plus, continuous plus and ground) nothing happens. The fuse in the back is ok. But unit and display unit are dead. Even if I switch on the power with SD-Card (with the rare or the unzipped file) nothing happens. Also, if I copy the rar file to a USB stick and connect it to one of the slots in the back. Nothing flashes, no sound.
Maybe someone has a link or a hint for me where I can start. If all else fails I will send the device back. But I'd like to get it up and running. BTW: The Astra version has no buttons on the display and not even a reset button...
Thanks in advance for any advice.

Send it back, or raise a dispute before it's too late, unit is defective.
