So it started when i accidentally got a RaspberryPI model A+ instead of B
I wanted to be able to use more than 1 usb port so i bought a powered usb hub that had a cool feature it had switches that let you turn on individual usb ports but it came without the dc adapter and when i went to try and look for it online i couldn't find the exact one
So i bought a break out board for a female usb micro B plug removed the dc jack and soldered it on where the DC jack was.
I connected the powered usb hub to a 5v 1A wall charger and it all lit up well everything seemed fine, i didn't smell burning plastic so i plugged it in to the pi.
Flipped on 3 usb ports, one for a memory stick another for a keyboard and the last one for a usb wifi adapter
But nothing came on the screen
The power LED was lit on the pi
I touched around and felt the CPU getting really hot so i disconnected it and panicked
it was plugged in for about 20-30 seconds
I looked around and thought i had everything well soldered but i had a 5v line connected to D- (data) by a thin strand of solder and it was going into the pi
Im not exactly sure if that was the problem but it seems like it
Now my Pi wont make it past the rainbow screen
I've read about polyfuses but i don't know exactly what they do
It was a christmas present and i feel bad for breaking it :/
Is there any way of getting it back?
Any help will be appreciated
Thank you in advance
