Is the editing mixed up or is the section 5 for "test the battery" supposed to be drain the original battery and charge? It looks like the new battery is put in and then it says to drain the original battery and recharge.
I've done this battery replacement twice. First time everything went well. 2nd time phone went into bootlooping. Put the previous battery back in and got normal functioning again. That obviously led me to suspect that the new battery was defective.
Not at all!😤 I accidentally dropped mine in the sink while I was washing my face. It was immersed in water for less than 3 seconds. My phone has been twitching ever since. I cannot open the back of my phone either. I have loved everything about my lg phones, until now.
Sorry, there is some bad advice in this video and it lead me to break a small piece (phone still works fine though, must be some antenna I don't need). I would advise to always remove the speaker part first and then remove the NFC/Qi-Charging part after that.
