YT9218 unit with 20200224 FW (1/16), radio issue - Android Head-Units

Dear all,
After trying many different firmwares, I've finally come across one that works for me (labeled as yt9216b 20200224). Rooted, installed RDS enabled fmradio.
This has worked before on a different FW, but for some reason there was no volume control whatsoever (full blast or mute). Now volume works, but I can't get the unit to use the radio chip anymore.
Also no RDS display in MTK engineering test mode.
How can I select the tuner? Factory settings always seems to revert to "fm inside".
I'm slightly frustrated now did somebody experience that one? Unit was branded as iMars 7 inch.
Greetings from NL

[Q] Connect G900F (lollipop from poland) to jvc nsx1 car stereo via MirrorLink

Hi all,
I have the JVC for few month now and never had the chance to try mirrorlink before.
When i heard the lollipop upgrade will have it, i was all exited...
I activated the MirrorLink option on my phone settings and connected the phone via dedicated MirrorLink usb in my JVC system.
After few seconds of "connecting" message, i got a "USB Communication Error"
Did someone had this problem before (Don't matter which devices, i mean with MirrorLink)?
Any ideas?
Do we have some MirrorLink experts here who can tell me how it works?
thnx
Hi,
I would say refer to JVC FAQ:
http://mirrorlink.jvc.com/faq.html
Do you have the software installed? I would also remind you that questions are posted in the Q&A thread not general ( a mod might slap you a little and move this)
B
I installed SlightROM (lollipop based) on my SGS5 w8 the other day and got the same error message when I enabled MirrorLink and connected to my JVC NSX1. I think the JVC unit will probably need a firmware update before it will work with the SGS5 running 5.0.

Xtrons TD695AB, how to root it ?

Hello everybody,
I just bought this model and install it in my car.
I wish to root it, but haven't found any explanation to do it, and don't know exactly the model of the CPU (0:30 in the video on Xtrons website, sorry but I'm not able to put the address).
Does somebody have a idea ?
Thank's
I recently bought an XTRONS D714A, Android 4. Kingroot worked, Towelroot not.
Hope this helps.
Hello,
Thank's for your reply, but after trying Kingroot, I got a message saying that this model (AC83XX) was not supported.
what a pity. I thought they are not very different.
What do you try next? Flash a custom firmware?
Hello,
I also have try Towelroot, but without success.
I don't think I will try a custom firmware, it seems difficult to find a root for this model, then a firmware it will be worse

I'm thinking of buying this head unit, what's your opinion of it?
Any flaws/downsides that you have discovered yet?
Can you post some more information about it, to go with the processor that you have found out? 'About device' etc.
It is a very good car radio, chip is the RK3188. Working flawless.
MCU says LM-AND841...
If you google it, there is almost nothing to find about that.
So I do not know if I should try to flash a custom firmware.
And I can not get into recovery, only the lying Android with a red triangle and a "!" appears.
I donĀ“t know if this has something to do with rooting.
TWRP or CWM can not be installed, device unknown.
So I even do not know how to flash a CFW.
vingtsept, can you try if you can get into recovery mode? Thanks in advance.
Did you try Kingoroot?
Do you know the "universal root for Rena3"? Maybe its worth a try? Worked with another Android-car-radio I had, but a bit older. Probably not the right thing...
http://androidstereo.mobile.eu.org/?dir=root
maybe here is something for you?
Hello,
Thank's for the link; I trued Kingoroot, but also without success.
I will stop my recherch for the moment, this model seems to be unknow by root apk.
At BlackSprint, Xtrons models are pleasant to use, very fast to start (more than the original car stereo !) and reagent.
But if you want a model who's can be rootable, it can be a better idea to choose another model than the TD695AB.
For exemple the XTRONS D714A like x_rainer_x (single DIN), or the Xtrons TD696A (double DIN) , which seems him to be rootable (thing to check).
At x_rainer_x, I have also try some key combinaison, but impossible to find how go to the recovery mode

Thanks for your help with this (and x_rainer_x too)
I was looking at the TD695AB because it was Quad Core on Android 4.4 and has all the features that I want, although finding out that it's not an MTCB/D unit is a disappointment.
The TD696A looks very nice but it has no front facing USB or SD slots and no 'hard' buttons, its also 50% again more expensive.
I think my other alternative is the TD618AS, it has a slightly smaller screen but is 1024 by 600; a higher resolution but an odd 'squashed' aspect ratio which I'll have to think about.
There are plenty of reports on here of MTCD units not going so well with Android 5.1 so I have reservations about it but at least I'll be able to put other ROMs on it to resolve some of the issues.
. . . . And I thought I had come to a decision, looks like more research & thinking ahead of me
Looks like the links didn't work...I'll try again:

Very low cellular signal

Hi,
As many of you I bought the yotaphone 2 in the chinese specials. In my case, ordered from aliexpress.
It came the YD206 with Android 4.4.
Upgraded to Android 5 and all the procedure went well. Some time later the upgrade to 6.0 was available OTA and I made it without problems.
This is my secondary phone and since then I have not used it with a sim card, only wifi. Today I inserted a sim card and the reception is very, very low compared with other phones. From what I have found around these forums is that I may have the wrong Radio software installed.
I was going to try to install other radio (CN or HK), but the official FTP is unavailable. I have googled for it, without sucess.
Can someone share with me the files and if possible share an article with instructions how to change only the radio software?
Thanks!

But it won't remember. If anyone can help me where to get firmware, or why it can't remember settings. Seller Ossuret Factory Store is bad. Sending videos of different models and useless solutions.
