ok, so not all CSI eeprom cannot be unlocked..ive unlocked other fones with the same chip, but with a trick..first do the usual pin-shorting, if not successful, assemble again the fone and factory reset..do again the pin-shorting, if no success, try 10 times pressing 'closed'.. then remove short..then 'closed'..the fone is now open..
if you have other ideas/experience pls post it in the forum,,lets just share ok..
regards,
stryker
