[Samsung Galaxy Tab S6 Questions & Answers] iMatthew:
I have what looks like a fixable problem, but I seem to be missing a step somehow, and could use some help.

The last firmware update, I downloaded the ROM. I use Windows 10. I have have had a long number of times using Odin without a problem.

Then I caused the problem by misreading the correct ROM, and I started Odin, but it froze completely, because I accidentally tried to install the LTE version instead of the WiFi T860.

The moment that happened it reset itself and went directly to Download Mode with a VBMeta error claiming it is incapable to verify the VBMeta.

I can get it to reset, and have found this I have done so far. While it is plugged into the USB on the laptop. If I unplugged it, and while unplugged holding down volume, while holding the power button to reset.

Everything else I have tried, it will always give the Download Mode with the VBMeta error.

But, if as soon as the screen goes black resetting, if I directly hold both vol up and vol down, and plug it back into the laptop at the same time.

When I do this it goes to the Download Mode with no error on screen.

But, when I try using Odin to attempt fixing it, it gives me a USB error on the laptop screen claiming a unknown device, so it won’t let me get Odin to start fixing the problem.

It is badly needs fixed for school work.

I will take and send any screen shots anyone asks if needed. I have verified the cord is the authentic USB cord. It has no problem using a different device. I have verified the USB connection works.

I already used Ccleaner to have my laptop cleared off of temp files and junk files. I have reset the laptop in case that is a problem. It has the latest Samsung USB driver installed.

I need any help anyone can assist me with. Feel free to ask any questions you have. I will be looking at XDA every couple of hours to give answers and try any suggestion.

SPECIAL TIPS FOR ROCO K706 UNITS

- If you hear an intermittent loss of audio, please try to reset your bluetooth settings, pressing the reset button in bluetooth app.

- The normal Autoscan can find only 18 stations like the original radio app because it's half handled by mcu. Anyway you can add more stations manually or doing an Autoseek.

The Autoseek don't use the builtin autoscan method so it's not limitied to only 18 stations. It's run slower but it the same time it can assign station names and logos if found.

- Using Google Maps there is a 1 second audio silence after the voice speak. I'm still trying to find a way to remove it but it's deeply coded in the system service and it's hard to find a solution.
[Android Head-Units] marioti:
i'm still asking for volume control like it is eg. in (internet) Car Radio (classic and reloaded) from google store,

For me it is necessery, because radio app is to quiet compare to any other app. And it is annoying to use eg. radio and navi in the same time

So is it possible to add this feature?

[Android Head-Units] KoTiX2:
I still have to look at the code of original service and framework but normally all the units have a volume settings to set individual volume values for radio, navi, music player Bluetooth etc..

Does this unit have it?

(I'm at work now and I cannot look at it)
[Android Head-Units] marioti:
understandable. And thank you.

Unfortunately no. This unit have only start settings volume level, which do nothing for default navigation
[Android Head-Units] mk148a:
I am buy your App, somhowmto setup default radio App to yours?
[Android Head-Units] KoTiX2:
That would need to modify the builtin launchers and service .

we need root access for that
[Android Head-Units] mk148a:
Hello,

I have robot Access via adb shell. How to do it?
[Android Head-Units] KoTiX2:
NavRadio 3.01 is coming out on playstore:

Fixed Russian and Serbian logos download

Fixed another bug on getting PTY image

Fix for editing null station Fix for S32F0 saving less than 6 stations

Fixed another crash when deleting last station

Addded TWUtil check for Topway units

Removed progress bar in the check dialog

Small change to get more RDS text for USA

Fixed automatic Dark/Light Mode for MTC
[Android Head-Units] ionutlup:
That last version not working in my S4 Hizpo.Not learning the frequencyes! 3.0 i mean,the older one working better!

I want to buyed but working one,please for test!
[Android Head-Units] hojnikb:
Awesome! Pretty cool that ROCO units got the support finally!

I'm assuming there's no option to remove the stock radio app and/or replace it with navradio+ ?
[Android Head-Units] KoTiX2:
Actually there is no way as i know...
[Android Head-Units] lucky_lucyan:
I will buy the application if it will work.

I installed the application from the xda website to see if it works, but after I search for radio stations and go on the road, none of them work.

I did the steps that are posted here, I hold down the frequency and pulled to that station and it still doesn't work, what can I do.

I have HU hizpo S8
[Android Head-Units] KoTiX2:
Please post some pictures of the system information screen of your unit showing the MCU number and radio type
[Android Head-Units] ionutlup:
Same here on Hizpo S4 4/32 bd37534 and ts4745 MCU QF03.V01.05.20230617.011021.
[Android Head-Units] KoTiX2:
Guys you need to be more specific or make a video that show the problem.

Did you run an autoscan?

Did you enabled the autoseek or normal scan?

Which radio region are you using?
[Android Head-Units] KoTiX2:
Guys you need to be more specific possibly make a video that show the problem.

Did you run an autoscan?

Did you enabled the autoseek or normal scan?

Which radio region are you using?
[Android Head-Units] ionutlup:
Est europe region.I run an autoscan with autoseek,the frequencies were fixed on the radio, but when I click on a certain station it doesn't switch there, nothing happens!
[Android Head-Units] KoTiX2:
Try the autoscan without autoseek.
[Android Head-Units] ionutlup:
Tried everything,same.
[Android Head-Units] ionutlup:
When I click on a fixed certain station it doesn't switch there!
[Android Head-Units] KoTiX2:
Please make a video:

Seek for a station holding the right arrow for 2 seconds, when it found one you can save/add it holding your finger in the middle of the screen until the add button come out.

Or press the stations/add option in the bottom bar.
[Android Head-Units] lucky_lucyan:
I put autoscan and normal scan

[Android Head-Units] james312:
@KoTiX2 is there even a minimal chance that you will someday create a version for the topway ts7 7731e ?
[Android Head-Units] KoTiX2:
No, because it use a different software from all other topways.

It's based on MTK code and I couldn't get it to work.

[Android Head-Units] KoTiX2:
Ok. I'll try to reproduce the problem on my unit and i will update the free version with all latest changes of the full one.

In the while you can do this:

- delete all stations (clear station list)

- search manually for a station and add it like you have done in the video holding finger in middle of the screen

-search for another station and add it again.

- do this for as many stations you need

Actually this is what the "Autoseek" should do but somehow on your unit doesn't work.

Please go to NavRadio settings/about Navradio and click on the gear icon, it will show some infos...Take a picture and send me it.

Thx ;)
[Android Head-Units] KoTiX2:
east europe on QF01 use the Frequency Range 65.00-74.00 Mhz with 0.03 Steps

Please set to EUROPE your radio region in NavRadio and it should work ok.

Try this new version i labeled the radio regions with relative frequency ranges:

NavRadio_FREE_3.01.apk
[Android Head-Units] ionutlup:
But I used in version 2.89,and all was ok!
[Android Head-Units] KoTiX2:
In version 2.89 the radio regions were not implemented correctly.

The app was using just the European ranges.

On other models like MTC, FYT and Topway for Poland and Romania freq ranges you have to set Europe.

East Europe is used for Russia and those counties who still use OIRT frequencies.
[Android Head-Units] ionutlup:
Thks.I will try it when I return from vacation!!
[Android Head-Units] KoTiX2:
NavRadio+ 3.02 available now:

Fixed Split screen for Topway and some related small bugs

Fixed Carousel text sizes in splitscreen

Possible fix for RDS text not showing in USA (liveRDS)

Adjusted InfoToast visibility

Adjusted Radio Regions Name for all models adding FM ranges

Fixed bring to Front NavRadio with TWRadioSelect app
[Android Head-Units] marioti:
I have basic 3.01 version now, but there is still less than 1sec gap every 35 sec

(TDA 7708)
[Android Head-Units] KoTiX2:
Try resetting the Bluetooth.

It doesn't happen to other users anymore
[Android Head-Units] marioti:
Ok, and what about this gap. Video is compiled from 3,

Do you know why station name pop-up show big and then smaller window
[Android Head-Units] TBM2:
Tried the free version on a Junsun X7 Pro 2K (Topway TS18). No issues afaics. Great job!

Just upgraded to the paid version. :giggle:
[Android Head-Units] marioti:
FYT unit it's a different story :)

Now, about the the volume gap, it is still there. Resetting bt work only till next cold boot,
[Android Head-Units] KoTiX2:
TS18 is a topway model but it doesn't matter here.

I cold boot my unit everytime i power it up because i have it on my desk and i cut the 12V to red and yellow wire with a switch and i d cannot reproduce the volume gap anymore. It just doesn't happen on my unit with latest 0715 firmware.

The only thing i can think for fixing the problem is to modify the QFservice replacing the original radio app link with NavRadio one. but this require root access....
[Android Head-Units] marioti:
So i don't know what is wrong with my HU. I have the latest SW and MCU also.

At first I ony reset the bt, but it didn't work. so i clear all paired devices and turn off/on BT, it work. But today, after a cold boot, Navradio wouldn't run, and it stuck in loading screen. So at first i ran the native radio app, then turn it off and clear from apps. Navradio start normally but volume restarting after every 35sec.

It is clearly shows to me it's time to change the HU to some FYT, like Teyes CC3, or so.
[Android Head-Units] hojnikb:
Dumb idea, but would it be possible to replace the stock radio app BY just naming navradio+ the same, so when installing apk, it would overwrite it?
[Android Head-Units] KoTiX2:
No, it doesn't work in this way.

It's android not windows.

The apps are identified by package name coded inside the app.
[Android Head-Units] hojnikb:
makes sense... So we'd need root access to overwrite stock radio app then?
[Android Head-Units] KoTiX2:
Need root access to write on system partition but making an app with same package name of original radio app is another story... too much code to modify in NavRadioto make it possible.

Anyway I have in mind a workaround that will help a bit the Launcher and other stuff to start NavRadio instead of the original radio app but i'll work on it after my vacations.

You won't see no new releases or anything from me until middle September.

;)
[Android Head-Units] hojnikb:
Awesome! The app is great as it is, but having more integration on roco units would just be icing on cake..
[Android Head-Units] marioti:
I was try resetting bluetooth direct via app manager, clearing the data, clearing all paired devices. And stil have this volume problem
[Android Head-Units] KoTiX2:
ok. I'll see what i can do after my vacations.

I'll be back on september...
[Android Head-Units] Kroko_xda:
Hi, I just bumped into the intermittent loss of audio as described here.

2 seconds gap every 35 seconds. Quite annoying.

I discovered it yesterday and tried several stuff (launchers, split screen, apps, reboots in different orders) to find the culprit because sometimes there was no loss.

Turns out it is linked to the Bluetooth as said by @KoTiX2 in the second post of this thread.

Removing all the (paired) devices did the trick.

Thank you
[Android Head-Units] Kroko_xda:
It may come back later I guess, I'll see.

When bluetooth list is empty, the audio loss is reproducible when clicking on the "magnifying glass" (refer to the attached video in post #55).

But it no longer did it once I paired my phone, but the audio loss still appears once, when closing the bluetooth app.

Obviously Bluetooth or Bluetooth app triggers something every 35 seconds that NavRadio doesn't like.

I hope this helps @KoTiX2 to improve even more this great app.
[Android Head-Units] marioti:
that's good for you. In my case problem return every time after a cold start. So it's a bit annoying to reset bt paired devices every time
[Android Head-Units] Kroko_xda:
I just tried hot and cold start on my unit --> it has not come back.

I will be on the look-out when it comes back.

I think the loss first appeared (roughly) after I paired my OBD2 adapter and I haven't paired it back yet. This bug might depend on the bluetooth devices you pair.

EDIT : as a matter of fact, the OBD2 adapter didn't actually worked (maybe because of the PIN needed to connect), it was a quick test in my car but my HU isn't in my car at the moment so I will try again (but later)
[Android Head-Units] Kroko_xda:
The audio loss described in post #52
[Android Head-Units] marioti:
I'm glad it work for you.

When you'll be ready do a road test with google maps, in my case, navigation commands affect navradio voice
[Android Head-Units] borek11498:
Hi,

Will this app support 4745 radio chip devices? Now when I install it i receive message that device not supported, do not buy premium one.
[Android Head-Units] KoTiX2:
Please post a picture of the system information screen showing the MCU number of your unit.
[Android Head-Units] borek11498:
Will be ok?
[Android Head-Units] KoTiX2:
No, it's not a K706 or any other compatible unit.

The radio chip is not what make the difference.

The MCU and manufacturer does it.
[Android Head-Units] borek11498:
Navradio+ will ever be working on this unit?
[Android Head-Units] KoTiX2:
No. It's not a best selling model or a model with good modding support.

Actually I don't even know what it is...
[Android Head-Units] borek11498:
That's Junsun V1 plus, 6/128 octa.
[Android Head-Units] Kroko_xda:
I tested on my desk with a mock GPS app (Lockito) and there is a (small) audio loss right after a navigation command indeed. This bug has been described already in this thread.

The two bugs may be related, I don't know.
[Android Head-Units] Kroko_xda:
Update after my post #54. The HU is installed in my car and the audio loss reappeared every 35s unfortunately :(

No more bug once I reset the bluetooth connections
[Android Head-Units] KoTiX2:
So, after you reset the Bluetooth connection the audio loss doesn't happen anymore?
[Android Head-Units] Kroko_xda:
Hi, I just tried in my car. No more audio loss every 35s even after reboot.

FYI my bluetooth list is currently empty.

When there is a Google Maps "itinerary indication", the radio volume is lower during the "anouncement" but right after there is the loss.
[Android Head-Units] Kroko_xda:
I still have the same behavior described in the video of post #55:

BLUETOOTH list empty, there is a 2 sec gap when the HU scans to find bluetooth devices (or whatever it triggers at that moment)
[Android Head-Units] KoTiX2:
The audio loss is caused by the service that handle the audio management between the various sources (Bluetooth, radio, android, etc..)

This service try to switch channel for some unknown reason when scanning Bluetooth or some other intermittent BT operation. Infact it also cause the "evey 35" seconds audio pause.

I cannot avoid this unless to modify the service apk ( need root access for that)

The only thing that I was able to do on my side is to request back the audio channel if it got lost. So you can hear that 1 sec silence.
[Android Head-Units] Kroko_xda:
Bummer!

Thanks for the explanation.
[Android Head-Units] Kepsor:
Hello!

I got the paid version of NavRadio+ and i'm very pleased with it. Does everything i wanted (except adding a normal Font to that existing "fancy" list). Anyway, all good with it except one big problem:

While NavRadio+ is running i get no sound from Google Maps or Waze!

The sound in the car lowers like it waits for the sound coming from Navigation but nothing happens, i get no audio cues from the Nav. After a few seconds (which i guess is the time for the Navigation to send its message) the Radio sounds goes up to normal. This scenario happens each time the Nav tries to send audio to the unit.

I tried everything i could find online regarding this issue but no luck. :(

Any thoughts?
[Android Head-Units] KoTiX2:
Did you set your default navi app in unit settings?

Are you using audio mix or switch? Level of mix?
[Android Head-Units] Kepsor:
The default Navi App is set by default to Waze. I've tried with Google Maps and iGo, same result.

I'm using Audio mix, wich i tried to various levels, nu luck. Currently set at 80%. I've also tried with switch, same result.
[Android Head-Units] KoTiX2:
Hi, i've tested waze and except the very first start up i've got no voice either but even with original app is the same so... Honestly i have no idea..

Anyway i tested again Maps and TomTom and I can confirm that they work ok except for the 1 sec silence after the voice announcement in maps due to the bad implemantation in the QF service of the audio switching that always prioritize the original radio app.

There isn't much that i can do on this side if everything is tighted up in QFservice and QFframework...
[Android Head-Units] Kepsor:
Thanks for the effort. I'll try some more tests and maybe i'll figure it out. If i'll find a solution, gonna keep you posted. Thanks again!

@KoTiX2 EDIT: It seems like it was the MCU firmware that wasn't updated to the latest version. After update, I now have sound from Waze/Google Maps over radio. Still, the mix is all over the place but at least now I have indications. :D

Hi

It works, no errors, but there is no sound, I can auto scan and it seems to be finding some stations but not with RDS or icons and I can't access the equalizer. main problem of coruse being no sound =)
[Android Head-Units] KoTiX2:
uhm...if sound and RDS don't work, it shouldn't find any stations either.

Are you sure that autoscan and seek+- are working?

Sent from RMX2202 using ReLabs
[Android Head-Units] DonAlcasan:
Well found stations is a stretch, seemed pretty random and most of them don't have any stations behind them, seek did nothing

[Android Head-Units] ScorpionSX:
Hello KoTiX, is there any update on possibility to remove the stock radio app on the K706 units?

Thanks.
[Android Head-Units] KoTiX2:
Not really...

Unfortunately the RadioProxy app cannot be used on K706 because of the different signature.

I'll try some experiments in the next weeks but i can't guarantee anything...
[Android Head-Units] ScorpionSX:
Thanks for the info, fingers crossed for some good outcome :)
[Android Head-Units] superatrain:
I also have one of these models (THEME1 app version, but same HW & MCU), and am eager for NavRadio support. Let me know if I can help test in any way!
[Android Head-Units] KoTiX2:
Sooner or later I'll buy one of these new models but it will take me months porting the app to it.

I really can't say when it will happen...
[Android Head-Units] ScorpionSX:
Hi KoTiX,

I know that RadioProxy is not available with its original purpose for K706 devices, but I would like to ask about using the app to launch another app installed on the radio.

In the other thread, you mention that I should create a RadioProxy.cfg file in /sdcard/RadioProxy/RadioProxy.cfg, however the K706 units don't have "sdcard".

Can you please give me some information how can I use it - if it's even possible? I would like it to launch app called com.qf.backcar.service.APP, which should launch the AUX app and show the camera connected to AUX in.

Thanks for info.
[Android Head-Units] KoTiX2:
Radioproxy and the original musicproxy can be used only on fyt units because they are signed with a standard Google signature.

FYT are the only ones devices that use the Google signature for their system apps so they can be replaced by the proxy apps.

K706 use proprietary signature and we cannot replace them.

There is nothing i can do about it. Sorry.
[Android Head-Units] ScorpionSX:
I understand the signature part, but wouldn't it be possible to at least use it as a "shortcut maker" for other apps? The front camera app doesn't really register for what I want to use it for, but the RadioProxy can be used. I only need it to start something else than the NavRadio app. That's why I wanted to use the config file, but I don't know where I should place the file.
[Android Head-Units] Mr.TT_NZ:
Here's a question for you @KoTiX2, if you could share some expertise:

To what extent does your app, or even the factory app, program the radio chip? I see that the radio chips do not retain any settings so they need to be fed the complete data string each time the radio section is started or switched from AM to FM or vice-versa, I don't know if that is done by the app or is an MCU function that you don't have access to.

Reason for the interest is that in the S2 (at least) the FM radio has severe permanent treble cut applied which should not be happening until the signal is very weak (or better still not at all), I see that this is programmable so the wrong parameters are being loaded into the chip by something. Also the AM section of the chip has selectable bandwidths, we really need to be able to set it to maximum as the default is very much less than even speech quality, even the max available choice is just speech quality not music but it would be a lot better than what the stock value is.

If you can help we could take this to PM so as to not derail the thread.
[Android Head-Units] KoTiX2:
Hi, where did you see this programmable treble cuts?

AM selectable bandwidths?

Please tell me where are you looking at these issues...
