I know this is an old thread but since I'm currently forced to use my nexus one (broken power button, repaired once under warranty, broke agai) as a temporary replacement, I've had to deal with the battery trick issue again.
I DON'T GET IT. Back when it was my main phone, the BATTERY TRICK worked fine, took a few times max. Now I have collated all the info I can find on how to do it (some of which is actually conflicting) and it WILL NOT WORK, except if I do it at my girlfriends house which MAKES NO SENSE.
IT IS NOT:
1.) The charger (various brands/both USB and wall socket)
2.) THe battery (authentic HTC battery)
3.) It doesn't work whether its fully charged (GREEN LIGHT) or charging up (ORANGE LIGHT)
4.) It doesnt work when I do it 20 times in a row with the "correct" timing (battery back in JUST as the light turns off), and not when I do it 20 times in the way which this video does it (waits for one orange flash before reinsertion)
5.) Have tried removing sim and sd card, charging it for days, just EVERYTHING.
Sorry just venting as this just boggles my mind.
Anyone have any input on this age old issue? What's weirdest is that it used to work fine for me around 2012. And no, not buying the goddamn flex for 30 dollars, I have enough issues getting my One X+ diagnosed (been waiting 3-4 weeks on some incompetent repair shop).
