Why I can't turn on my iPhone after 6r8 repair?
sorry for my language, I can't write in English fluently.
I have an iPhone 3GS 32 GB. Before I give him to my friend, It turns on, and work, but he don't have backlight. So I decided to repair It. I bought 6r8 coil and give It to my friend to solder It. After that, my phone won't turn on. I plug in It to my PC, trying DFU mode, and It's not working. Have anybody any solutions, how to repair it?
Is this a good question?
