I really appreciate the breakdown and explanation. It was definitely helpful and informative.
From sifting through the forums, I’ve also come to the understanding that reflow only works in certain scenarios.
I was hoping to get lucky I guess, but I totally understand the steps and procedures to diagnose a problem and how important it is just in general when trying to repair electronics.
This is definitely something I will need to learn and practice in order to get a hang of.
I’ve read about this fuel gauge, if I remember correctly, there’s a way to confirm this through checking to see if the switch is patched or not, which in this case it’s not.
I just plugged it into the PC, and with the jig in place, I was able to successfully enter RCM mode. (I obviously couldn’t inject anything because it’s patched)
I was also able to get some readings…
Is it safe to assume I didn’t fry the SoC? 
(If so, huge sigh of relief because i’m learning immensely.)
It seems I need to find what I can on this fuel gauge. I did find quite a lot, but the information was as mentioned, all over. I’ll try to do a search, if you or anyone else here doesn’t mind narrowing down a specific thread I should read over, please feel free. I’m at the excited stage, with hopes I might actually be able to fix this switch.
Also, any comments on the rework station I bought? Know anything about the quality or reliability?
