Hi, Im new to the forum, first of all I've read lots of posts to ensure there is no previous answer to this problem. I have an Optimus Black, I rooted it around 6 months ago, everything went fine. Later I started to have problems to charge the phone, I read some posts and noticed this is common hardware problem, this has been fixed, but now it doesn't turn on! It does charge but can't turn on, so I've tried pluging to PC holding volume key, it goes isnto S/W update, but the PC wont recognize this is plugged in. I tried using LG recovery, no luck. Smartflash is no use since PC doesnt detect my phone I uninstalled and reinstalled drivers several times Sending it to LG is no option, if you think customer service sucks, you should try LG service at Mexico. Please give me your suggestions, if I manage my PC to recognize the phone I think it can be solved with smartflash Thank you!!!
