Hello, btw Nice Post, i wonder why this didnt come before when i goggled it.. and thank you for such wonderful detailed reverse engineering, because, i knew this was a hidden fact not just a reverse polarity lighting to color charging port LED stating what its doing.
my reply here is regards to a Anonymous on soldering :)
soldering have several type of solder and rasin core mixture... materials you use also relates to type of quality soldering gun in hand plus the ambient room temerature effects your soldering results.. ( i mention this part is by experience, realizing i was having a hell of a time with small sodering tool & softer solder material...so if you try to do this in a garage vs not doing it in door room then add this ambient temp as factor of your failed attempts... ie...cold-solder )
avoid preheating with lighter fluid of the sonder tool tip to cheat time
in between soldering cycles, refresh tip of the soldering tool with proper material provided by the package of your soldering gun
hands-on skill instruction on soldering:
0. tools neede, stonger solder
material will be recommended if wire tends to flex alot for application this will harden and lasts longer.
1. at all possible time AVOID contact with fresh cut of the wiring conductor
2. if #1 failed, cut off, repeat until you succeed
3. preheat wire-conductor with soldering tool just for a few sec immediately add solder in 3-way position where contact of wire conductor meets your soldering tool tip heated ready which will transfer the conductor heat into solder , instant bonding of solder will submerge together
4. apply circuit board trace conductor same approach as you succeeded in pre-solder the wire-conductor
5. applied the beautiful soldered wire-conductor tip you just made final step to circuit board surace where both will become a perfection in bonding
