As a hobby project for my daughter I wanted to build in an old Samsung tab 3 P5220 in her bureau. I intended to charge the tab 3 directly, without the already broken battery.
I cut the six battery wires, two black, two blue and two red. I soldered the two black wires to the black wire of a USB cable and did the same with the two red ones. Then I connected the two blue wires with a 10k ohm resistor to ground (black wires). After a successful boot the tab 3 was showing, within a couple of seconds, the message: Closing down the apps, as the device is overheating, which was not the case of course..
I tried using a 5 volt charger, wired to an USB cable (default) with the above result, but also tried to switched to 4.5 volt, (only the Samsung tab 3 words appeared, presumable because of a too low voltage the boot did not succeeded). I hooked up to another laptop's USB port, same overheating "error" message. I can use (according to a screen message) calls and use the contacts, but the rest is blocked. Is a hardware sensor responsible for this issue? I can't seem to find an solution in the software for this overheating problem either. My daughter like to use a my little pony app and is not so much interested in calling nor contacts..
Any help or suggestion would be greatly appreciated.
