Samsung i780 cannot remove the PIN lock!

[dcuk7]

Hi all,

One of the users in our company has locked himself out of his i780 by forgetting the 4-digit PIN he set on the device (not the SIM PIN).

The problem I have is that it is running one of the older ROM's that did not have the hard reset button combination on it so I cannot reset it at all. It also won't enter bootloader mode using the usual combination (although this may be because of the countdown timer on the device not accepting input).

Anyone got any ideas on what I can do next?

Thanks.

I wonder if you can short certain pins on the flash chip to destroy the checksum and thus cause the device to reset itself - this method was used in the LinkSys WRT54G router and some MP3 players..

did you try reflashing the phone with new firmware? might help since the pin is set on operating system level (afaik), the firmware upgrade is done on bootloader level.

But he can't get into the loader mode, so Mirage is a no-go.. I suppose the phone doesent even connect to ActiveSync, hm? If it would then the official HL1/2 updaters are able to reset the phone into the loader mode and flash it

[dcuk7]

Correct, I cannot get it into bootloader mode because the usual key combo does not work and activesync refuses to recognise the phone until the PIN is entered so I cannot use Mirage or the official updaters!

Looks like I'll have to send it off to Samsung!

Cheers guys.

try contacting them first by phone and see if they can't help out. otherwise you'll have to wait for a looong time ;)

Yeah, I've sent phones to them before, they do take a while.

They say they need them back to take the lock off so looks like it'll take a while!

Moral of this story: Don't forget that damn PIN! :)

Doesn't it wipe itself after the 50th attempt?

How old is that version? before Nov2007? Can you post the version number? something like "i780XXHA4"

By Omnia this ok
1. type *7465625*638*# to set
2. type your MCC/MNC code (list here: http://en.wikipedia.org/wiki/Mobile_Network_Code), e.g.26003 for Polish ORANGE
3. type your new NCK (12345678), then OK
3. type *#7465625 to check your lock
4. type #7465625*638*# and type your NCK (12345678)
5. enjoy.
