you can still do this?
I changed the charging PCB on my Samsung by opening the case using my plectrum and then replacing the part.
You can do this too - the battery pack was right there, well everything was, it just needs a few screws and components to remove.
I spent about 20 mins just ogling at the engineering and design to get all this into such a compact form factor.
Thank God for the industrious Asians.
