04.05.2011 Samsung Nexus S (i9023) Unbrick Boot repair supported

Samsung I9023 is based on the S5PCxxx Processor (ARM core is Cortex-A8).
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.
Current resurrector has two different versions of primary boot loaders (PBL) embedded. This depends on hardware version of your phone which boot to use, thus in case of failure (cannot enter download mode after resurrection) of first loader try selecting another.
In case after resurrection (after you have tried with both boot versions) the download mode is not initiated (LCD remains blank) do repeat resurrection with ‘Clone Gremlin zone’ option checked.
