KT3 (8th generation) battery charging problem

[dom123dom]

I bought a broken kindle from the classifieds, the guy I bought it from seemed clueless and genuine. He told me it was showing low battery, I think he said it wouldn't charge and he tried to use it and then got the error message.

What is it?

The serial number starts with G000K9 which I looked up, its a KT3 (Kindle Basic 2 (Black) 8th Generation).

The case identifies it as model SY69JL

The version code on the screen is 3330460020


What are the symptoms?

- White screen with Error Code 0 and Battery Invalid -22 message.
- Without wall charger power attached I get nothing from it at all, power button does nothing.
- With power attached to wall I get intermittent green flashing LED.
- With wall power when I press the power button it goes green, then amber then off.

I attached a serial port to it, I see the following, I connected power and pressed Enter repeatedly until it interrupted boot and I'm now at uBoot prompt.

I have the feeling either the battery is really dead and it needs a new one or the charging port is faulty. Any suggestions what I could do from here to check the device's health, the state of the battery and the state of the usb port?

I might be imaging in it, but I think the usb port feels a bit sort of loose inside it when the cable is in it, I am able to move the cable around a little and occasionally get a weak green light to briefly appear. With the case off the port seems secure on the board.

The keypad errors **might** be from the abnormally low battery.
**might**


All KT(*) devices are IR scanner rather than capacitive touch screens (note the extra thickness of the bezel).
So do an extra careful job of cleaning the bezel edge where it meets the display surface. Those keypad system errors might from the scanner not being able to "see" through the dirt.


A **good** (4.2 volt) Li-Ion battery should never go that low - it has been over discharged too many times and for too long.
Buy a new one.


Then fix the charging problem, which you most likely have already found - broken solder joins between connector and motherboard.
(PS: Don't leave the new battery in the device except long enough to make tests of repair efforts, you don't want to over discharge it until you get the charging circuit working again.)


Ask google or other web-search tool about re-flowing possible cracked or broken SMD connections. You should find the info under "SMD board rework" topic.
Be sure to look up the temperature profile to use.


Since the connector is at the very edge of the motherboard, you should be able to use make-shift tools to re-flow the solder joints.
(Ah, battery removed from system, motherboard removed and by itself, metal foil used as a heat shield/hot-air deflector away from all parts other than the connector, ... (you get the idea - hot air to connector/motherboard area ONLY). )


Of course, if you have access to an SMD board re-work station, all the better.

Thanks I will do a some research on the charging problem, the solder looks ok but then I don't have any experience with what I'm looking for so I'll see if I can find some examples. I also don't have hot air or SMD rework station.

I'll also try to lookup what to clean the screen with, I have some standard PC screen cleaner spray, would that be ok?

I'm booting it outside the case, does that matter? I thought I read in another post that it doesn't matter. It's also face down but I have tried face up as well.


This was a boot using the USB port connected to a PC.

I have found that if I don't interrupt uboot the device spams the keypad errors constantly, which I assume is what discharges the battery eventually.

I'll order a new battery too. [Edit] battery ordered, see below post.

[dom123dom]

Based on this thread https://www.mobileread.com/forums/sh...=286988&page=3 I cleaned the screen with a dry Microfibre cloth, it has made no difference, still get the keypad errors.

[dom123dom]

Ordered this battery:
https://www.aliexpress.com/item/3-7V...24254c4dr1jYWo

7-10 days delivery, will wait until I have it before I proceed.

[dom123dom]

My new battery finally arrived...

The device has been in the cupboard for a few weeks while I waiting.

Now when it boots all I get is this:

U-Boot 2014.04 (Jul 24 2018 - 06:41:12)

S/N: G000Kxxxxxxxxxx
I2C: ready
DRAM: MR5=0x6,MR6=0x3 512 MiB

I tried swapping the new battery in, it does the same thing. Actually a small difference...the new battery boots it, the old one doesn't which seems to point me to the charging circuit.

I also now have a hot air gun so some reflow on the weekend might be in order, as suggested by knc1

I will disconnect new battery and investigate the charging circuit further with a better magnifier.

[dom123dom]

Update, while fiddling about I seem to have got the charging cable in the right spot, it now has a solid amber light. This is on old battery so I will leave it as long as it has an amber light and see if it charges up.

Also different is I put it on a white sheet of paper and the charge port hanging over edge of the desk...not sure why that might have made a difference but we'll see what happens....

Added a couple of photos, can't see anything obviously wrong with the solder points.

Not much experience with this though, is there any solder points I can't see underneath the port or something?

How obvious is it to actually see an issue, maybe there's a solder problem there I can't see?

Please describe the problem you are having.

The problem is it won't boot and it won't charge. I replaced the battery, it still won't boot beyond the quote above.

I've been playing with it more and wiggling the charging cable, the charging light comes on and off depending on positioning of the cable in the port. I think your initial advice was correct, I need to reflow or replace the charging port.

I'm watching some vids on how to do that, it looks quite challenging without a microscope. My eyesight is not as good as it once was!

The solder joints look ok so maybe it's the port itself that's faulty. Any tips to view or clean inside the charging port somehow?

Not sure if the firmware is now damaged too as it will not boot like it previously did with charging errors on the serial. I guess I will worry about that after I get it to charge/respond consistently.

That it only charges when the cable's in exactly the right position probably means dodgy connections from the charging port to the motherboard.

But it could also be the cable - did you get the cable with the Kindle, or is this a known good cable?

It's a cable connected to a Samsung charger i got with a phone. I use it to charge other stuff all the time (including my PW2) so I think it's ok.

Edit: just plugged it into my Bluetooth headphones and started charging them immediately.

It's not the cable then. So it's either the connector itself, or the solder joints from the connector to the motherboard.

From the photo (as much as can be seen in a photo), the four anchoring solder points look OK, but the actual power and data connections are (I think) under the connector.

But I have no practical experience with that particular connector.

Yeah i agree they seem to look ok so maybe it is the connector itself.

I'll grab some pics of the front view as well.
