10.01.2012   Samsung GT-i8150 Galaxy W (Samsung Ancora) Unbrick – Boot repair supported

Resurrecting Samsung I8150 is easy. Phone is auto powered on with USB Data Cable connected to the PC while battery is connected.
Please note, MSM8255T is dual core chipset – it has ARM11 and Qualcomm Scorpion cores. During power on sequence only ARM11 core is visible on the JTAG chain. If boots are not completely damaged and it comes up to initializing of the Scorpion core then Scorpion core appears on the JTAG chain too. This will shift ARM11 from TAP0 into TAP1 position on the chain, while current resurrector has the ARM11 core hardcoded at TAP0 position. Thus make sure to establish JTAG connection in the time range while Scorpion core is not visible yet.
