Yeah, I also had to change the port on mine twice.

Also there was a chinese site with step by step instructions and pictures.

Strangely, I can't see any loose connections when wiggling the cable (although the connection does get dropped when the cable is in certain positions). I'm wondering if this could be a software issue as well as a hardware issue, as in it's not keeping track of the actual charge correctly. I managed to really quickly charge it from 30% to 90+%, had dinner, came back to the charging tablet, and suddenly the charge was way down to 54% again, and going down fast. The device doesn't heat up, either, so it probably isn't caused by the CPUs going berserk. I'll order a new charging port regardless, but the way it's looking right now, I don't know if it'll solve anything.

Did you have issues similar to what I described above? I really hope it's just this one component that's broken.

Thanks for mentioning this. Luckily I don't have an SD card inserted with 64GB of storage already there, but I would absolutely have forgotten all about it if I did.

Yeah, it was charging only in certain positions and if force was applied for instance from below. Finally I was fed up with it, opened it, then brought it in a service center to solder a new port (didn't want to leave the opening to them. Same thing after an year.

Mine broke twice as my kids use it from time to time.

Thank you! I'll make sure to replace it, then.

Un-be-lie-va-ble. I got the port replaced not even a month ago and it's broken again already. It always claims it's charging, but it never actually charges. I even made sure to be as gentle as possible whenever I had to plug it in the past couple of weeks! At least this time the current doesn't flow the wrong way, it just doesn't charge even though it knows it's plugged in. What a horrifyingly badly designed port!

Come to think of it, would it technically be possible to install a different port (as in USB-C, or mini-USB, or whatever) instead of the horrible micro-USB port? I find conflicting statements when trying to look this up, so I assume it isn't possible, but I'd still like to know for sure.

Just to make it clear, I don't care one bit about the actual USB connectivity as I access the filesystem wirelessly anyway, all I'd want to work is the charging aspect. I wouldn't mind cutting a slightly larger hole in the plastic at all if it meant I'd get a more solid connection that wouldn't cost me a fortune having to replace it every other week.

Depends totally on the component layout, if you find an usb-c connector with same or nearly same trace layout then I suppose there is no reason it shouldn't work.

the best you can do is to solder cable instead of port

Thanks, guys. I'll look into both options.
