Member: 1060066 Status: Offline Thanks Meter: 1 | I need some help from experts I have a big problem here and I need some help A few days ago, wrongly I changed a setting in engineer menu and my MT6225 based NokLa N83 set is gone, it's completely dead! This is the layout of the phone. Because of having to repair it myself (some money problems and I'm living in Turkey, there is no service for these kinds of cell phones ), I have opened the phone. This is the picture of the circuit part of the phone. Firstly, I have to say that, I don't have any device (or any box). I only got COM port on my old computer. (old PIII can do this job perfectly), I also got data cable of the phone but it's a USB cable and I guess I can't use Anyway, I found pins of RS232 (com port), It seems I have to use PIN-2 (RX) , PIN-3 (TX) and PIN-5 (Ground) on RS232 But as you can see on phone there are P_KEY and VBAT pins, and I don't know what are these What are these pins? Also I got another question, if I format my phone, do I have to flash the OS again ? or format is just removing the changes after factory?? If anyone can help me, I would be very appriciated, I'm just a student and all of my money is gone to buy this phone. I really need to fix it |
