[Nook Touch General] Bobby55:
Hello, everyone!

I used NST (BNRV300) for a few years and everything was fine. But then I got battery problems - it started switching off randomly when charge goes down for more than 50%. I ordered a new battery in hope to replace it. Unfortunately, it was a fake battery, and even worse, it had a fitting connector with + and - pins switched. When I connected it, it burned my charge controller.

Now, the reader loads and works as usually, but discharges waaaay too fast - in a hour or two. Even when it's not working. Even when switched off. And it discharges the battery completely - to less than 1 volt. Of course it also doesn't charge it at all. Replacement of the controller is a huge pain - I cannot solder/unsolder it, because I don't own a hot air soldering gun and I cannot find exactly the same part for replacement. Repair guys ask about $30 for replacing the controller, and I think it's just too much for an old gadget.

I thought about buying a whole motherboard, and "powerbookmedic" place even has it for cheap, but they don't deliver in my country (Russia).

I thought about using an external charge controller, like those cheap TP4056-based boards from aliexpress. It would allow me to charge the battery and prevent it from full discharge, but what to do with the fast discharging? Maybe there is some way to exclude the onboard controller from work at all and use external one?
[Nook Touch General] Renate:
The problem with the quick discharge could either be that the battery is junk or that the blown charge controller is leaking a lot.

With the NST in suspend mode the leakage current should be around 1 mA.

Sure, you could throw on a separate LiPo charger.
[Nook Touch General] Bobby55:
Thank you very much! I measured current in suspended and power off modes, and both gave me whopping 0.1 A! I identified the controller - it's TI BQ24072.

[IMG="Before"]https://img.xda-cdn.com/kz37bftWQ1xr_gn2bWUtUTdEB6w=/https%3A%2F%2Fimg.xda-cdn.com%2FN-1xX-7gyqfh4ATpjWLOTPqZCDA%3D%2Fhttps%253A%252F%252Fs21.postimg.org%252Ftavjj30gn%252FP_20161006_110816.jpg[/IMG]

So, I decided to mutilate the mainboard for a bit and get rid of the faulty controller. That's what I got:

[IMG="After"]https://img.xda-cdn.com/DD5KTjo4AObDt_C-iEODhMwVc9Y=/https%3A%2F%2Fimg.xda-cdn.com%2FkYc8qEh--QtYanZc5Ir1PUFy8Xw%3D%2Fhttps%253A%252F%252Fs21.postimg.org%252Fpsjjmozkn%252FP_20161010_181939.jpg[/IMG]

But it didn't work. Current remained to be 100 mA. Then I touched components of the PCB and found out, that the nearest IC gets really hot even when the reader switched off. I identified it as TI bq27520-G1 fuel gauge. Unfortunately, it's not just some dumb IC that I can get rid off, but a micro controller that monitors battery health and communicates with the CPU by i2c protocol... Even worse, it has LDO functions, but I'm not sure it's actually used. But, I think maybe the system actually able to run without it? Anyway, this controller sniffs when the battery is connected and signals outside (by putting one of its pins to active low level) if the battery can be used. The pin itself is unaccessible, because it's under the component. But I bet one of these testing pads on PCB connected to it. Don't you know, for any chance, which one could it be?
[Nook Touch General] Renate:
The NST takes about a peak of 300 mA on boot up.

See: http://xdaforums.com/showthread.php?p=46801874#post46801874

(Read further and there is a reference to the battery connector.)

Battery health gets checked in two places (if I remember correctly).

uboot checks it and refuses to proceed if there is no battery at all.

The charger daemon will power down the NST if the battery is unhealthy.

You can try disabling the charger daemon by commenting out the line in init.rc or else deleting the file.

I'm not sure if you can get things to work like that.

Obviously, you can not do this to the internal flash on a device that won't boot.

You can either write a bootable SD (we still have that luxury on the NST)

or else use OmapLink to feed a boot image over USB.

When doing low-level stuff like this, there are two ways of getting feedback.

You can watch the current consumption with it's characteristic startup signature.

You can use the UART console to watch the boot up messages.

The standard UART out on the NST is at 1.8V levels, so you may need to hack a buffer.

(There is also a 3.3V UART, but you'd have to configure it and the buffer is not even enabled until much later.)

I'll try disabling the charger daemon on my NST later and see if it still works.
[Nook Touch General] Bobby55:
Well, the device boots and works, and I guess I can disable the deamon, as you said, but I don't think it will resolve anything for now.

If it was possible to switch off battery check for uboot, that would be promising. But I have no idea how to do anything about it.

I still think, that if I could put low level on BAT_GOOD pin of fuel gauge IC, that maybe would make the uboot to allow system to start normally.

Not sure what use I can make from UART feed, but may be cool to take a look on it. I found that thread about making 3.3 UART working during boot. Maybe it would work.
[Nook Touch General] Renate:
Since you're dealing with low-level problems and since the uboot and the kernel are separately configured and already configured for the 1.8V UART, I'd stick with that.
[Nook Touch General] Renate:
Hmm, it's been a while, but I don't see anything there.

On later stuff it's either chargerd or healthd.

It may be built right into the kernel.

[T-Mobile Samsung Galaxy S 4] gaww:
Is there or will there be any new firmware that would allow the S4 to get the new LTE-A 4x4 MIMO speeds rolled out by TMo in late September? ODIN'd only the LTE-A S7 CP on the only custom ROM there and over doubled the download speeds.

Update - The "will there be" above is probably not realistic, as there has not been any new firmware for it for some time. Wouldn't really care about not having a TMo 6.0 TW ROM if they would just send out a modem but that is also unlikely.
[T-Mobile Samsung Galaxy S 4] dennis5pia:
The S4 doesn't have the necessary hardware to support 4x4. Dude you are talking about an old tech device.

So what exactly can the new assistant do that makes it that much better? Is it something the current google now + tasker can't do?
[Google Pixel Questions & Answers] doitright:
Its still a gimmick.
[Google Pixel Questions & Answers] matrix0886:
For now, there's not too much difference. Assistant does have a little bit of edge over Now. It tries to offer simpler, shorter answers. It also learns and adapts, like an actual A.I. Now is just a simple Google search with voice. Assistant is more geared towards A.I. and having as close to an actual conversation as possible. I like Assistant. Been using it regularly on the Allo app. But, it's up to personal preference. For some, Assistant is great and they'll love it. For others, Now is just fine and they'll get along with no problems not having Assistant.

I personally love Assistant, but if for some reason I chose not to upgrade to the Pixel (still deciding) i'll be perfectly fine sticking with Now or opening up Allo to use Assistant (though it is slightly more limited in the Allo app than it is as an official OS feature).

[Galaxy S6 Q&A, Help & Troubleshooting] sofir786:
So this is my issue, the battery percentage seems to fluctuate badly, there will be one instance where it will charge till 75% and then stop charging and it will say like 1 minute till full charge then never go beyond 75%.

Another instance is the battery will go down really quickly to 1% then it will operate on 1% for like upto 2 hours and then shut down finally.

Things I've done so far.

Changed rom clean flash, wiped caches, flashed stock in odin.

The only thing now is my bootloader is from an older firmware than the rom firmware currently installed which is cas rom.

Any insight or help would be great full. Thank you

[Galaxy S6 Q&A, Help & Troubleshooting] N00BY0815:
I would simply first try another cable and also wall adaper. If this doesnt change anything, make a backup and go FULL stock. Not just flashing some oartitions, but your last stock ROM completely. If this doesn't make a change, then it probably is your battery, that is faulty. Try to have Samsung exchange it then. I just hope that we won't have similar problems, as the Note and S7 ppl.

Would have been awesome to have a smaller, shorter version of that light bar on the center of the bottom bezel and have it blend into the bezel to be unseen when not lit up like the the Nexus 4 notification light.
