Finally downloaded dump.bin from my phone and opened it in the recommended hex editor(cygnus) . If i follow the instructions it says click edit and select block and start offset @ 20000......but i do not see how to select block!!! soooooooooo close, please help !!

right on zener, i just finished those steps myself....just got the phone open and trying to get that damn metal plate over the test points off safely.

could you please tell where you found "select block" in hex editor ???
