Steps:

1. Assemble required items from the Essential Electronics Kit
2. Phillits 00 bit
3. Guitar pick
4. Solder
5. The 1.5mm bevel worked best

6. Optional - Chem pen with isopropyl alcohol
7. Optional - No clean flux pen

8. Remove the sticker to expose the 2 x phillips screws and unscrew both

9. Use the picks to open the larger edge first
10. Then start on the corner, this can be quite tricky
11. Get the end fully unlatched

12. Continue working around the entire case until it is seperated

13. Remove the 4 x phillips head screws show above
14. The battery and board can then be removed from the plastic case

15. You can then confirm the solder joint issue
16. Just sitting being plugged in, no lights illuminate
17. With gentle squeezing pressure on the charging port the charge indication lights illuminate
18. Additionally inspect the solder joint an identify if there is a break in the joint

19. Remove the three screws to allow the PCB to move to give additional space to resolder the joint
20. 2 x picks help seperate and hold the space open for soldering

21. Using the flux, heat the joint back up.
22. I found that the highest setting on the soldering iron didn't reflow the existing solder so I added some additional solder
23. Using the chem pen clean with isopropyl alcohol
24. Test to see if it charges without external intervention

25. Re-assemble noting there is a small and large notch at the top and bottom to aid alignment-continued next step
