=== Test points ===

There are some easily accessible test points (i.e. bigsqare and not very small round pads behind the rf shields).

Theses test points are divided in two groups (when looking from behind the phone) :

• A group of 7 TPs at the lower left of the PCB. Accessible from the battery compartment without disassembly except for the first one. From left to right : * '''TP16''': JTAG TDO * '''TP9''': CTS MODEM * '''TP13''': TX MODEM * '''TP14''': RX MODEM * '''TP3''': DL PWR * '''TP107''': GND * '''TP19''': VBAT
• A group of 5 TPs at the middle/upper right of the PCB. Theses are not accessible without disassembly, but could be by cutting a small plastic strip just right of the hole made for the battery connector. From left to right: * '''TP18''': JTAG TMS * '''TP20''': BAT_TEMP * '''TP17''': JTAG TCK * '''TP15''': VCHG * '''TP8''': JTAG TDI
