Any Solution for auto 4 locks for 3310? - GSM-Forum

xpmobile · 01-20-2002, 05:01

Hi,

I had came across 2 sets of 4 locks for the Nokia 3310. and all cases are geniune without using any flasher or software before. Whats wrong with it. The imei is intact. 4 lock in FFFFFF closed mode. Tested it on the Nokia Tool. Some people saying that it is the Cobba faulty. But how to solve it? Any solution without changing the cobba. Can I use a full flash or upgrading to remove it?

it happened to me many times, ur error is you overwrite the original eeprom contents our fone. all u can do is upload the original eeprom which i think u have a backup.

Hi,

Thanks alot. But this isn't caused by that. The phones just stated "SIMCARD NOT ACCEPTED" while coming out from the lift and network search <img src="eek.gif" border="0"> <img src="eek.gif" border="0"> <img src="eek.gif" border="0"> . This is an X-FILE that I ever came across

Hi!

I once had a 3310 with all 4 locks closed but IMEI intact....

I reflashed the same MCU+PPM (so that i don't have to calculate FAID) and hoted the phone... I also reseted the phone to factory defaults... After that phone was ok...!

C ya!

Hi,

This is very common problem. There is this start up self test which check the Cobba parallel interface, but it;s look like the test is not reliable enough.

This could happen if you have broken ball under Cobba ( loose conn. ) or more possible some small quantity of water under the chip.

So the the data still flow between the DSP and Cobba , but small impedance between data pins cause errors one security data and locks are calculated wrong.

Observe Cobba carefully, rework, clean, reball or even change.

Best Regards, Alex
