Hi Anesteticus84,

So, not sure you will believe this, but I think I just had your issue :( . I really couldn't believe, my watch completely dead (the battery), I just got a new Samsung S7 Edge, and was using that to charge (has the Fast Charge feature, not that that would make a difference, because it only works with fast ready phones at 9v, our watches are regulated at 5v). However, all I know is, it was charging fast (it does have high current at 5v), I went to turn on the watch at a point when it should have been close to fully charged and it wouldn't give a display, either the battery % with phone not on, or NO phone on display, I got neither. I held down power button, but again nothing. I hooked up MY power cable, and still no display, at least for couple minutes, finally I got battery % zero, power off display, WTF?? <

Once at 2%, I was able to turn it back on, I have been able to charge since, currently at NOOOOOOOO, just turned off again. Can't seem to turn it on, it was at about 35% I think, I have a feeling it will work again, but something is definitely wrong. Right now it won't charge, my USB /Voltage Current reader shows 0A before, when it was charging it was capped at 700mA, doesn't feel hot.

Again, the only change her has been my charge, but it shouldn't had made a difference because of voltage regulation and no recognition from watches non-fast charging CPU. Either way, don't agree that you did this as well, if you are trying to get a warranty claim, ANY NEWS? I obviously made my warranty null and void when I modified my charging connection, even though the charging circuit protection hasn't been manipulated.

Right before sending this, I went to plug it in one more time and realized something else you said, it looks like the screen is on, the watch is getting hotter, this would explain the amps charging are at 0, that is what happens when fully charged, it just started charging again, but still no display. I wish I could disconnect the stupid battery, but again, it seems to be under the Mainboard, I don't want to go there...yet. I might have one way to short it out, or it will work again maybe when the battery drains. I will let you know.

Cheers.

Just found battery connector, it's on the side of Main board facing up. It's a tiny ribbon cable close to the buttons, on end close to band without clasp..just an FYI, not sure it helps me at this point. Well, I was able to shut off my watch..for sure.
[Other SmartWatches] pablo11:
Maybe you guys should read back through this thread. All this has been documented here to help you guys.

There's a rooted custom rom out there in a separate thread. Just spend a bit of time reading up on it and you'll be ok.
[Other SmartWatches] Bedeadu:
Apparently I just figured this out myself, the long way, thanks for the assistance. I came on board intending to help someone, but agree, I should have searched.

Anyways, to assist my fellow hated non searcher, Anesteticus84, this should help with no screen or power.

Confirmed with my own results tonight, it is a power/charging/crap battery issue, I probably introduced my watch to it yesterday with my high amp charger.

Back to life?

- Try using the charger that came with the device, or one that would power a Bluetooth headset or other low power device

- if at any point the screen goes blank, and the watch heats up, unplug, flip watch over

- grab a metal paper clip, medium flat head screwdriver, etc.., and place between the top 2of4 pins on the watches base cover.

- The top is where the metal clasp is is on the wrist band, by doing this you are shorting the - & + pins. Nothing visually will happen right away, but the watch should start to cool.

Wait about 5 min for the battery to cool, keep trying until you get above above 50% and you can at least do a reset. However, this I learned is not a fix.

At one point, I unplugged at 26% from one room, plugged in to a different charger in another, then it showed 78%, which is when I reset.

Hopefully the custom ROM Pablo11 mentioned will do the trick. Also be sure to use a low current charger, maybe get a monitor. Hope that helps.

Battery connector, can pull this to shutdown also:
[Other SmartWatches] Anesteticus84:
Hi guys,

I'm not sure I got the point.

I read the whole thread from the beginning but none of you experienced the same issue I described (with exception of Bedeadu, currently my fellow in misfortune). I already tried a factory reset without success: the issue is still appairing. So, I don't think that it can be solved with a different rom. I'll try again, as kindly suggested, to solve the issue by charging the watch with a different charger even if currently it stays turned on only if continuosly in charge.

Thanks
[Other SmartWatches] Bedeadu:
I haven't gotten that far yet, busy with some other stuff. But I think the point Pablo11 is making, is search the custom ROM thread. I have a feeling, the dev. might have been able make use of better battery management, either in new kernel, or battery management in Android (not sure how this would help, agreed, in Android)

My last post was only to get you to a common point, I wasn't sure you were able to even turn it on, I did state factory reset didn't fix the issue.

You can search out the custom ROM'S threads, when I have the time, and find my stupid sticky piece, I will take more thorough look.
[Other SmartWatches] Bedeadu:
So Pablo11, I have spent my time 'searching' through both threads mentioned. I do see some evidence documented discussing users experiencing this. However, I do not see any answers to this issue. You are telling us to go ahead root and flash our watches with a custom ROM, yet I can't find any evidence in Lockfish's thread that his ROM actually fixes the issue. It says it helps with general battery drain, but that isn't the issue here.

I am not saying I wont do this at some point, I have done so on all of my others, I just like to wait a few months. Sometimes, I build my own personal ROM'S, however, I am unfamiliar with MTK devices at the moment. Mostly, I just want to see an actual explanation of how it would be fixed. Because as it stands to me this is complete crap h/w.

My watch is off when the issue happens. I know it was discussed to use low current chargers, and I do agree with this, might have to build an ultra low current charger from the looks of things at this point.

Please if I have missed a thread or post, maybe be kind and try to point it out. Otherwise, I would like more evidence before before having to resort to this method to fix an issue that came out of seeming nowhere, and wasn't fixed by a factory reset.

One thing too, with the battery acting this crazy, I am a little scared to go through a bunch of flash procedures. This was true when I did the factory reset, luckily it made it through one.

If I can't find these answers in the next day or 2, I might try wiring in an old cell phone battery to the solder joints on the Mainboards battery F-connector, see how it functions after that.

Cheers

Access to K18 Heart Rate Monitor

Hi. I know im a bit off-topic but im struggling with this watch, which is the hardware i need to use for my Master's thesis.

I need to access the heart rate monitor but i have some major problems.

Android APi only introduced Heart Rate Sensor support in API 20 and the watch has API 19.

The native application does not use any permission in the manifest, because i've read it, meaning they built the application using NDK, leading me to assume there is no macro string to ask permission to access the sensor.

After listing all the sensors and respective types, finding the HeartRate Monitor type, which is 87, i cant access to it, getting the following error:

"03-14 21:00:22.237 730-805/? E/SensorService: Error activating sensor 5 (Operation not permitted)"

I tryed looking for an alternative using NDK but there is also no support for body sensors.

So my question is:

Did any of you for some reason got access to the sensor raw data (not the BPM tho, that i can get from the pixart app database), or developed a ROM where the watch runs API 20 so i can use Android API instead?

I'm kinda desperate, since i tryed allmost everything to access the sensor.

As a note, i rooted the device with all the files in the previous posts, and tryed to grant my application root access so it wouldn't be blocked when trying to reach the sensor, again, failed =(.

Hope you can help me.

Thanks in advance.
[Other SmartWatches] Bedeadu:
After my watch kept turning off, or freezing while charging off or on, I bit the bullet and created a quick test setup.

As I said I would do, removed battery cable, soldered small leads under the connection on mainboard. Then I attached to an 1880mah 3.7v battery:

It hasn't been to long yet, but no shutdowns. Haha and massive battery hasn't moved. So I haven't tried charging yet.
[Other SmartWatches] pablo11:
I was going say that the others who had this issue have removed the back case, disconnected the battery and then re-attached it,

This cured it for them. Maybe you have a bad battery....
[Other SmartWatches] cyrux75:
I'm not an expert here, but most probably the access is locked by running stock app. Have you tried to disable the app and restart the watch?
[Other SmartWatches] pablo11:
Good idea. You can use gesture search or the search settings apps from playstore to get to the advanced app settings menu.

Disable any app which could access the sensor and then check it with Mobile uncle mtk engineering tools.
[Other SmartWatches] kotana105:
Yolo, with 1880mah you can use it for a week now, but on your table instead of your wrist :D:D:D
[Other SmartWatches] mefsantos:
I' ve tryed to disable the stock apps yet still got the same error. Altho i noticed some errors when rebooting the watch. Especifically:

When i try to list all the devices, types and vendors, i get all the sensors correctly, although, when i try to access most of the sensors i get the same error.

Plus, with using with CPU-Z the only sensor retrieving information was the accelerometer , all the other ones were blank.

I guess i most likely will have to use a "self-made" driver and get access on my own, won't i ? :/
[Other SmartWatches] Bedeadu:
After my test, my watch ran for 24hrs on wifi/BT without fail, this wouldn't happen with stock battery. So yes, it seems the batteries are crap. I think I exposed my watch to it with my fast charger, only because it was fine before for 2 months. Again crap, because it shouldn't make a difference.

Look, I see you commenting on here for a while now about a bricked watch you have been working with. You haven't seemed to eager to share much info with me, if I offended you sorry. But right now I have a useless watch.

I just need to know if you have seen the battery, and if so, have any tips for removing Mainboard. Again, I don't want a brick, and from experience, the buttons, speaker and mic look like they could pose a problem. Antennas seem fine, just desolder.

I found http://pages.ebay.com/link/?nav=item.view&id=121897354854&alt=web THIS battery on ebay and was hoping to confirm it might fit, giving me 5 weeks (delivery time always sucks) to carefully figure out how to take apart my device, but any advice is always appreciated especially when dealing with my own $$.

UPDATE LINK WON'T WORK:

Here is screenshot of battery from ebay link:

Cheers
[Other SmartWatches] pablo11:
I am not holding back anything.

I have a full time job and a young family. It's purely about priorities.

I'll get it done as soon as I get enough time. There's another guy who's taken the watch apart to put the antenna inside the watch. He must have seen the battery. Worth asking....
[Other SmartWatches] Bedeadu:
Thanks Pablo, I completely understand other things getting in the way.

I quoted a comment to the user with antenna inside in another thread also.

Unfortunately seeing two now like this, there might be more to come. One thing I haven't mentioned yet, is over the past month, while monitoring Current levels, every more frequently there would be a dip while charging where current drop to 0 for split second then goes back to normal. It got more frequent, maybe another indication of faulty battery.

Worst case, I have an 800mah battery do any day now for another project. For time being, just put that in a sports band to make use of watch.
[Other SmartWatches] Anesteticus84:
Hi Bedeadu, Pablo11,

I saw the mentioned thread. I would say thanks to you for your really appreciated and useful support.

I put the phone constantly attached to phone wall charger and it remains turned on. So, it is clear I need, as well as Bedeadu, to change the battery.

So, I would say thanks to you in advance if you could add further instructions/steps to do it (unfortunately i'm not so expert with this kind of stuff).

(in the meanwile I'll wait in silence until I 'll find useful further info to do it by myself)

Thank you
[Other SmartWatches] Bedeadu:
Hi Anesteticus84,

Just to be clear, when you say you are running fine with watch on and connected to wall charger, is that with or without battery connector connected?

My issue and I thought yours, is that if stock battery IS connected, the watch WILL act up, screen go blank and get hot, not turn off. I also just thought you needed a battery connected to turn the watch on, even with wall power, maybe I was wrong.
[Other SmartWatches] rockabilly:
My K8 also with battery-death. Open it today and select the battery. It's not so easy I hoped.

Awesome Rockabilly, and I the follow up questions Loki..i have about 20 different ebay batteries in my ebay list, waiting for this, different dimensions, and most def., hight capacity.

Just about to eat when i saw this, i will get back with options, i hope.

Rockabilly, do you think you still have a working from after dissassembly (aside from battery). Any specific point to mention? Buttons, mic, speaker?

Cheers again, I will let you know soon about battery. Dinner getting cold.

---------- Post added at 06:46 PM ---------- Previous post was at 05:56 PM ----------

One more question. Where the battery connector is, do we have same thickness here, as rest of battery, 5.6mm?

Hope this works from google translator:

Noch eine Frage. Wenn die Batteriestecker ist , haben wir gleiche Dicke in diesem Bereich als Rest der Batterie , 5,6 mm haben ?

Also again:

wenn Sie irgendwelche Teile der Demontage wissen , dass die meisten hart waren . Alles, was besonderes mit den Tasten , Mikrofon oder Lautsprecher ? Ich weiß schon, Antennen ablöten .

Cheers
[Other SmartWatches] Bedeadu:
I might have to just take it apart, I am going to have to anyways. I just like as much knowledge as I can get, I used to do similar for a living. People can do all sorts of stupid things, myself included without service manual. Looks easier then most cell phones these days however.

I agree there might be some space there, unless main piece sits there when it comes back on. Once I see this myself, i can measure with caliper to make sure.

Ebay really only has a 400mah spec'd closest. There are a few 500 600 options around 35x30x6..I need to see if they could fit, and how much height we have. With height, could go to 800.....doubtful, but maybe.

Options I saw, Seems Ebay seller Tesky12 has this niche cornered for the most part.

- 30x30x6 400mah

- 30x25x6 420mah

- 30mm x 20mm x 7mm 450mah

- 35mm x 30mm x 5mm 450mah

- 35x25x6 500mah

- 35x30x5 500mah

- 40x30x6 800mah

- 40x30x7 850mah

They are more I am sure. These looked closest options to me.
[Other SmartWatches] rockabilly:
Bigger 30x30mm is not posible, onlyan thickness can be bigger up to max 7mm (better max 6mm).

The battery is in a 'cage' that not allow get bigger size...

My orginal battery not overall the same thickness. Looks like blows up.

[Other SmartWatches] Bedeadu:
Thanks Rockabilly, I see what you mean then if caged. Although kind of sucks then, unless we kind find another, means stuck with the 420mah option I found above, I think 30x25x6.

I'm waiting for a GearBest answer about my faulty K8 mini... If Gearbest does not answer me I'll give up and I'll purchase another one (probably FinoW X5 that is the same watch but with Amoled screen.)

If so... I will disassemble it to see how is inside and I will try to bring it back to life and show it here.

I'm almost sure that If I could solder the flex buttons of the Normal K8 (3 buttons) or K9 (2 Buttons) I could bring it back to life forcing it to Recovery mode.... (the problem with my watch is that Non PC nor MACs recognize it and it just have 1 button so I can not enter it to recovery mode (its currently bricked))
[Other SmartWatches] rockabilly:
Why recovery mode? Flash firmware with "sp flash tool", you need no buttons for this.

I think this is worth bringing up again and should be in the OP with a big red warning.

"To help support the explosion of mobile Internet usage and give customers a great experience, AT&T plans to fully discontinue service on its 2G wireless networks by approximately January 1, 2017."

"AT&T expects to fully discontinue service on our 2G network by approximately January 1, 2017. As AT&T progressively frees up valuable spectrum for our mobile broadband network, we may conclude that some markets or territories need to turn down 2G service prior to the nationwide turndown."

I am sure Rogers Canada will follow suite, unless more users need it for longer transmission distances in the Great White North (maybe 2G works better in Igloos).

Either way, so nice of them to get rid of this service, I am sure it will make life so much easier for its Users :(. Guess it will ensure fast speeds on their Network though, making them always look good (admit didn't read into the full story yet).

Update on battery search:

Based on Rockabilly's latest comment, that battery had to be 30x30mm, I just found and ordered this. So far, I only found the one seller, so hope it lasts, it is 550mah @ 30x30x5mm, Seems perfect fit(I got 3 pack, basically buy 2 get 1 free):

No link search on ebay: '503030 battery' it should be only battery options to come up, seller is electrinic_cindy 97% rating.

Hope that helps, now to not break anything else when disassembling.
[Other SmartWatches] rockabilly:
...can't find on ebay (de). But find with your search key "503030 battery" on aliexpress. Thank you :)

[Other SmartWatches] Anesteticus84:
I mean: I didn't try to disassemble the watch. If i put it in charging wtih a wall charger for phones it stays on without problems. Unfortunately, I hadn't try to flash it with the proposed rom yet (due to hard work activities done in the past days: but someone pays me for that :) ). So, I would try the rom this weekend but i would be sure that it makes sense: I never had issues with the original rom so I thought it is due to the fault battery (I used a twall charger adapter of my Samsung Tab 2 in the past two months to charge the watch).

By reading the comments in the thread (thansk to rockabilly, pablo11 for pictures) I didn' understand yet how to proceed with teardown without worries: could you please help me understand if something has to be usnoldered?

Thanks
[Other SmartWatches] pablo11:
If you dismantle the watch you will have to use a soldering iron to disconnect the strap antennas.

If you are lucky enough to be able to remove the pins which hold the strap in place you may be able to get away without the soldering iron.

Better to ask [MENTION=238911]rockabilly[/MENTION]
[Other SmartWatches] rockabilly:
Without soldering iron is possible but more difficult. Not about the antenna for wifi and gps, you can remove them at the strap. But if you not disconnect the speaker cables it is more difficult not damage something by handle remove battery.
