Troubleshooting How I fixed the loose connector/cover losing charge problem on my 8yo Kindle Oasis

[tinbilly]

Recently the charging contacts on my Kindle Oasis and its cover could not connect to each other. As a result, the cover could not charge the KOA. Here what I did to fix the issue.

Tools/Material needed:
- An electric soldering-iron
- Some lead-free solder
- A three-cornered file

Steps I took:
1. Open the back panel of the KOA
2. With the soldering-iron and the solder, create 5 small welds on top the KOA's 5-pin charging connector/port
3. Gently use the three-corner file to flatten down the welds a little bit so that the charging cover's 5-pin connector can contact with the KOA's connector
4. Put the panel back to the KOA
5. Done

Here is the KOA's 5-pin connector looks like after I completed the steps above:
