목록중에 쓸만한 모드 있을까요???^^
다운로드 모드를 OFF하는 저항은 255k네요..
Desk Dock: 365K (also works with 1K)
Car Dock: 619K
In these modes audio output can be switched to pins D- and D+ of the USB port (D- is left) but this is not done by default, see this thread.
Serial port/UART: RID_FM_BOOT_OFF_UART (523K)
Read the rest of this thread for more details on using this port.
Other resistor values that also enable the serial port:
RID_AUD_DEV_TY_2 (80.07K): Doesn't switch the phone on, but produces bootlog output on the serial port when you switch it on manually. The bootlog output only starts partway through the second bootloader, rather than from the start of the primary bootloader.
UART_CABLE (150K): Same as RID_AUD_DEV_TY_2
Download mode: 301K (this thread).
Here is a list of all the resistor values, from fsa9480_i2c.h in the open source code for JPM. The resistor goes from pin 4 to pin 5 of the micro USB plug (full details on how to wire this up are in this thread). When you connect the plug with the resistor (in Froyo) you should see some messages from the fsa9480 driver in the kernel log, which you can view with the "dmesg" command.
