Kindle Fire 1st gen.

I got this for about $15 off eBay and opened it up as my first repair to fix the charge port which was not only obviously defective but fell out upon opening from its solder. I tried in vain to solder it back, damaged a solder pad, and did some research that mentioned use of cold solder technique, which I'm not familiar with, in combination with a hot solder application to the sides.

Is there any way to get this board repaired?

your pic's didn't show up
 
Get another one for $15......

seriously - any other repairs would cost you more than getting another unit (hopefully one with a different fault) that you could swap working parts between.

That would actually defeat the purpose. I got it specifically with practicing on fixing the port in mind, because I have a Kindle Fire 7 that needs a better port.
 
Still no pics....

I suspect the charge port module attaches to the main board via an SMD type connector and ribbon assembly?

Bit pictures will reveal the solution....
 
Sir Nisar-von-Voltenbräackter . . . .

My first unit is getting to be almost 4 yrs old so I guess that I will only HAVE to be going inside . . . . . for its eventual battery replacement.

This is very complete info and the only comment I can make is to use a WELL tinned small tip and a soldering iron of adequate heat level so that you can get in and out in a hurry. Also, use plenty of rosin flux.
Now, the closest I can think of your "cold" soldering reference , was possibly the technique of REFLOW soldering . That is where two connections, that are to be joined are BOTH pre tinned.
Of course there is going to be some fool that takes a new connector and THINKS that the current state of tinning on the unit is being good enough. Thinking that extra heat, flux and fresh solder will be adequate . . . . NOT.
If both parts are pre tined they will just immediately inter flow their solder coats together, just as soon as a dot of solder is added for initiating effective and rapid heat transfer.

USELESS TUBE . . . . . HOWTODOITTOIT . . . .
