Circuit schematic in PDF for the MI2 CDMA variant at the P2 prototype stage, with 1227 in the name most likely a date code for the drawing set. A CDMA board has a different radio section from the GSM/WCDMA version, so this set suits repairs on that specific model. Use it to trace power rails from the PMIC, follow signal paths between the SoC, modem and peripherals, and identify the value of a shorted capacitor. Open it in any PDF reader and check that the board stage matches the phone being repaired.
