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.
To resurrect Samsung I8150:

•  Solder JTAG cable to Samsung I8150 JTAG pads;
•  Make sure Samsung I8150 is selected in the list of models;
•  Insert battery and connect USB Data cable;
•  If you use only battery, press Power On key;
•  Click Resurrect button;
•  Wait till software signals a successful operation completion;
•  Disconnect power supply, de-solder JTAG wires;

31.12.2011   A new Year gift ! Samsung GT-i9103 Galaxy Z / Galaxy R (TEGRA2)  Boot repair / Unbrick

Resurrecting Samsung I9103 is easy.
Phone is auto powered on with USB Data Cable connected to the PC while battery is inside; sometimes pressing Power On key during connection may be required. External power supply can be used too.
During some definite startup time (1…3 seconds) TEGRA2 chipsets are not detected via JTAG interface (this could be due to FUSE-d security): that is, on contrary to other devices, which being fused are detected via JTAG but non-haltable, TEGRA2 chipsets give ‘Nothing Detected’ response (though TCK-RTCK pair keeps functioning ok).
Please note: If during resurrection of dead unit the JTAG connection cannot be established (nothing is detected) then re-try with the NRST wire disconnected.

To resurrect Samsung I9103:

•  Solder JTAG cable to Samsung I9103 JTAG pads;
•  Insert USB Data cable into board and PC;
•  Make sure Samsung I9103 is selected in the list of models;
•  Click Resurrect button;
•  If nothing is detected then try with NRST wire disconnected;
•  Wait till software signals a successful operation completion;
•  Disconnect power supply, de-solder JTAG wires;

Now phone is in bootable condition, that is, even if it does not start up normally, you can flash it using known flashing methods.
