Hello to all,

I would like to start by saying i have a nexus 6 and stock android 6.0.1.

Recently (probably after the 6.0.1 update) i encountered the following problem.

1. i download a game or an app.

2. the game asks me to connect to google, so it can show my activities and achievements in the google play games.

3. if i don't like the game first i disconnect it from the account by going to settings-google-connected apps.

4. i press the game-i press disconnect-i tap on the also delete all activities-i press disconnect.

5. i get "couldn't disconnect and the game name"

6. if i just press disconnect with out pressing the "delete all activities" the game disconnects but all info stay in the google play games.

Has any one else encountered this problem.

thanks in advance

Hi,

My LG G3 died during the night when a firmware update started and the battery was low.

Now the phone isn't booting. It gets stuck at the LG logo.

I can put the phone into download mode but not much else. It it's recognized by any PC I've plugged it into.

Hello everyone!

I have purchased from an asian store this gear, actually I noticed a great problem.

I am italian so the s-voice command languages preset are different from mine, I thought it was so easy to install different languages and just connecting on a pc.

So this is my question:

How can i install s-voice italian language on this asian gear?

I can't always speak english just for beginning the call on my note 3 :D it's quite different the pronunciation of the names.

Anyone could help me?
[Samsung Gear S2] konnybroe:
Hey, do you have any news regarding this topic. I get a Hong Kong version and there is only french, chinese, korean, englisch... available.

This should not be a problem but you have to pronounce Names like englisch which is quite annoying due to I am german.

I am also in contact with Samsung though, since it is still a Samsung Item and they should take care of what is going to sell here in germany.

So if there is any chance to add languages to the gear, tell us! We would realy appreciate it!

[MTCB Hardware Development] hadjistyllis:
Hi guys.:)

I successfully fix radio high frequencies using some hardware mods.:D

Why I need these mod?

Radio quality is bad even if you use darkleo MCU mod. You can't hear frequencies more than 442hz because of hardware limitation (Chinese wrong calculations maybe). Doing this mod You can hear clear and great quality sound (up to 25,6khz, full range for analog FM radio )

How to do the mod?

You have to discover sound filter that comes from radio tuner (TDA or whatever). See pictures for KGL4 that filter was split into 2 parts (different than any other tutorial).

Special Thanks to Russian guys that first do this mod and release tutorial (although slightly different than mine's) and vaonline for his tutorial for KYD (http://home.scarlet.be/~spb27160/witson/Witson.html). All head units has the same/similar hardware.

What You need to buy.

1) 2 1nf 0603 (1608 metric) SMD Ceramic Chip Capacitors (you can find a lot on ebay or whatever). See pictures.

2) Pen style soldering iron (see pictures)

3) of course soldering paste.

See wiring diagram and PCB pictures that shows filter line and what to change.

You will notice extreme difference in sound (I still can't believe the difference) .

I also Upload old russian's tutorial in rtf format (google translated)

Pictures from PDA forum for some devices

GOOD LUCK FOR TESTER.

[MTCB Hardware Development] ArakniD:
Does this also apply to the BN/HA models you think?
[MTCB Hardware Development] hadjistyllis:
It should, although boards are different and need some investigation to find the right parts, as capacitor numbers may be different.

If you can take clear hd board photos from top and from bottom I can try to help.

Dear hadjustyllis,

What do think about these mods what [MENTION=6738895]kumarai[/MENTION] shared on 4pda?
[MTCB Hardware Development] hadjistyllis:
Russian guys also change the whole circuit for some devices.

For example for KGL they changes also resistors and .....

AI only change the 2 capacitor and I get lost high frequencies. Bass its was ok from the beginning.

So if you have great soldering skill you can follow russian guys.

Thanks for pda link, some may find it usefull.
[MTCB Hardware Development] gb37270:

The sound is really better.

Before I was not able to capture some stations, now this is ok.

[MTCB Hardware Development] gordonscicluna:
Thanks. I thought so, after studying your mod and the russian text. Will do once i get the 1 nano caps. I have 2.2nano and they are slightly bigger. Do you think size bigger caps will fit on the board in same place
[MTCB Hardware Development] hadjistyllis:
Mmmm parts are small enough and no more space. So use the recommented one as frequencies are case sensitive

[MTCB Hardware Development] jakejm79:
I just did the same mod has [MENTION=7342972]gordonscicluna[/MENTION] and I have 2 questions:

1. I used 2.2nF caps, is this a big deal seems like it is much close to the 1nF that was used (I had ordered 2.2 since the Russian tutorial had mentioned 2-4nf), I assume if the original ones were 35nF or so the 2.2 should be much better but maybe not as perfect as 1nF?

2. What are the additional resistor changes for? The link for the JY images on the Russian website showed to change those as well, but when I opened up my JY unit it didn't look the same, so I only changed the caps (since [MENTION=6374083]hadjistyllis[/MENTION] had pointed out which ones to change on the JY board that I have).
[MTCB Hardware Development] gordonscicluna:
According to hadjystillis's calculations 2.2nf will not liberate all the high frequencies.. You will miss the 15khz band. Using 1nf you will open all spectrum by far.
[MTCB Hardware Development] jakejm79:
Hmmm maybe I will go back in there, it does sound better that is for sure
[MTCB Hardware Development] popeye70:
Change capacitors to have an higher cutoff frequency, and change resistors to modify the pass-band original gain.
[MTCB Hardware Development] jakejm79:
Thank you, do you think it is really needed to change the resistors too? I have done the audio mod if that makes any difference
[MTCB Hardware Development] gordonscicluna:
I dont think you need to change resistors. Changing only caps gives sound same as mp3
[MTCB Hardware Development] jakejm79:
Thanks [MENTION=7342972]gordonscicluna[/MENTION] I was thinking the same thing, I don't want to go pushing my luck with all this SMD soldering. Once my 1nF caps arrive I will install those and then seal the unit up and never open it again.
[MTCB Hardware Development] popeye70:
Sorry i can't tell about that, i never heard a resistor modified unit playing...

But by reading on XDA and 4pda too, it seems that most people change only capacitors.
[MTCB Hardware Development] hadjistyllis:
Change only capacitor will make you happy ( russian guys on some models change the whole thing , some resistor goes from line to parallel etc.) no needed if the only thing you want is high frequencies

Hi, I have the same layout as yours, and while the desoldering of the old piece went quick, re-soldering the new 0603's is tricky. I feel I can accidentally burn another resistor or two in there. Any tips / hack to make things a bit easier to solder things back? Thanks!

[MTCB Hardware Development] jakejm79:
Does anyone know if this mod can effect radio reception, just got a replacement main board and did the mod, all I get is static and it doesn't auto tune to any radio stations. Didn't test the main board before hand so not sure if I screwed up the mod (tho all looks good) or if it was bad before hand.
[MTCB Hardware Development] jrgalang:
I know if there's just static, sometimes the radio chip setting in the Factory Settings screen can be one reason. For me I chipped one of the traces on C212. Fortunately I got to solder C213 right... so my radio still works, but the effect is that I only have one channel going (passenger side) when using radio. That's why I'm also trying to look for a parts supplier for KGL on a separate thread. I'm hoping that will be cheaper than having to buy a new unit altogether just to fix my FM.

ADD: So for those who want to try but that's not so good with soldering components like I am, I'd strongly recommend seeking help from someone experienced with soldering parts as small as these 0603 packages. They're inconveniently placed in some of the boards, and you can likewise end up burning other caps while you're at it if you're not too good with soldering.
[MTCB Hardware Development] jakejm79:
I tried all the settings for the radio software and they all come up with silence other than the original one so I'm pretty sure that is right.

I had done the mod previously on a different board with no issues just the wrong caps. I will take a closer look and measure the resistance of the surrounding resistors to make sure they are still good.

The sound comes from both channels fine, just I have no reception, its like the antenna is unplugged, but if I unplug the antenna the static goes away, only comes back when I plug it in. Next time I will test the unit before starting on it, but I feel like it was bad to start with, also the BT doesn't want to pair with my phone now and hitting the home button closes out the radio/music app whereas before it would leave it playing and kick me back to the home screen.
[MTCB Hardware Development] typos1:
Try updating the MCU to the latest version.
[MTCB Hardware Development] marchnz:
In my evaluation, just remove the capacitor and dont replace it because there will be sufficient bandpass filtering built into the tuner.

Regards,

Marc
[MTCB Hardware Development] RabbidHampster:
Could you elaborate on this? You are saying that we could simply remove the caps and still achieve the same results. Is this just your guess or did this work for you?

Anyone else confirm?
[MTCB Hardware Development] jakejm79:
IME removing the caps (or at least not having them connected properly) results in no sound.
[MTCB Hardware Development] marchnz:
Removing c212 and 213 from the OP cannot result in no sound. The correct capacitors form the RC filter, with the capacitor the path to ground. So, suggest you need to check you have indeed located the correct capacitors.

From the schematic, the circuit is a buffer stage before the codec. The input being from the tuner is already likely to contain a bandpass filter and suggest the bandpass being modified here was simply a case of the MTC engineer following the application notes for the CODEC.

If removing resulted in high pitch noise or oscillation, then yes it is serving a purpose. If not, the filter cap is redundant.

Edit: Note from the OP schematic diagram, this is atleast a second order RC (Butterworth) filter - check the values of c30 and c31, these should be the same recommended value. Removing C212 and C213 will simply reduce the roll off and a single order filter be sufficient for the purpose. However you might notice a greater amound of 'hiss' if listening to AM stations.

Regards,

Marc
[MTCB Hardware Development] marchnz:
Not an MTCB. Mod is probably not applicable. Is the audio poor or has a noticable loss in high mid to high (treble)?

If so, you will need to trace audio path from tuner to audio mixer. This will require reverse enginnering to document the schematic just as the original effort by Russian forum members.

I have a klyde unit almost three years now , and finally I changed the two capacitors with 1nf.. It was easy to desolder them but didnt have special tools or the stable hand needed so I took it to mobile phone repair shop here in greece to solder the 1nf caps (10€ please...)

so it sounds good! high frequencies and the radio is usable again!

I have one problem losing the right channel.

When I use the radio the right channel is missing.

when I use music player , mp3 , etc the right channel comes back again.

Can soldering around there do any damage so to lose the right channel?

thanks!
