RIFF JTAG -Samsung Galaxy II, OMAP4430 version supported (Samsung i9100G, Samsung i9108)

07.10.2011    Samsung Galaxy II, OMAP4430 version supported (Samsung i9100G, Samsung i9108)

Samsung I9108 is based on the OMAP4430 Processor (Cortex-A9 Dual-Core). JTAG pads are very small; professional experience in soldering is required to connect wires to the JTAG interface. There is a big variety of versions of Galaxy II devices: GT-I9100, GT-I9100G, GT-I9100L, GT-I9100M, GT-I9100T, GT-I9101, GT-I9103, GT-I9108, GT-I9188, and maybe more. Some of them are based on different hardware platform – the Samsung S5PV310 (Cortex-A9 Dual-Core). Thus make sure first which exact hardware version you have on hands.

Note, one simple way to connect over JTAG – connect USB cable to PC and insert battery. In this case phone is automatically powered on.
Current DLL is still a beta one. It will work only with phones which have killed X-Loader.

Phone has such booting sequence: ROM → FBL → IBL → PBL → SBL. Current resurrector will resurrect Partition Table (PIT) and SBL zones which are located in the iNAND (eMMC) memory.

Note, one simple way to connect over JTAG – connect USB cable to PC and insert battery. In this case phone is automatically powered on. But note, in very rare cases it is possible that you will have to hold Power On key during initial connection.
