2x3310 killed by sim card - GSM-Forum

Gor333 · 09-16-2003, 08:38

The phone says `Contact Service` and don't flashing.
Help me please.

Medz · 09-21-2003, 14:09

Well i think U'v got inoghe jokes replyments, so as the phn is
responding "contact service"+dosent accepting flashing + a
past history with the Sim-Card.
So it is obvioslly clear that it is the power controlling IC(N201)
wich it is called the ccont (writen on the IC),try to apply a persistenet moderate presure over it (doble faced adhesive tape)
Or U must have inoughe experience to reflow the chip.

Try to check it out what is the main problem of the "Contact Service". Use Eeprom tools 3.1, connect phone to mbus, let the phone on, and clik on the test. U'll see the problem of "Contact Service"

@Gor333
You should first start from CS point.
I doubt that you killed two phones with SIM. CCONT is not so stupid IC.

vule · 09-26-2003, 13:30

Are You sure that is impossible to kill CCONT with simcard???

Then You haven't seen cards from my network...:-D

Now seriously...I have a sim which will make ur ccont very, VERY hot... Most of phones can not read this sim... But N3310 and ericsson T10 still can...

b0ba · 09-26-2003, 17:44

I saw cards from local operator Kyivstar.
Most phones doesn't accpet them excpet phones you ment. But no phone was killed with SIM. Nonsense.

Of corse not Because SIM data bus had been decouplled by a
dual resistor R213 ( 100 ohm). wich reduces the current to 30
- 50 ma in max. load.
but the SIM card it self as a single chip ( memory ) or dual
(memory +UProscesor), Is liablle to have internal dammage
and when the silicon-arsenade changes its physical structure
it changes from semiconductor to conductor- maybe with resistance to compleete short- That could be happend across
the +ve & -ve lines of U'r SIM cards.

I believe what u said. That would be a short circuit SIM

So ur network have SIM like that???

why just N3310 Ericsson T1 can read this kind of SIM can u explain it ???

Are you in a posts run?

@Medz:
Do pyu know what currant is neede to burn 100 Ohms resistor on 3.6 volts?
You need to place a pure conductor (Sorryy for my English but it's Cuprum or Ferum, may be Gold or Slver).

@tedjo13 : Don't be angry, but have you ever studied Ohm's Law?

Medz · 09-27-2003, 01:41

@boba ...
Yes from the law R=V/I.
then tollyrance power of the resistor =V * I
I can calaulate it .............

b0ba · 09-28-2003, 17:16

Sorry man

willy · 09-28-2003, 18:00

without check real reason by use wintesla or ....
other way to think where is problem become useless !

ps. if post out out title will be split and drop to recycle box !

on how many watt of 100 Ohm resistor man? 0.5 watt, 1 watt, 5 watt, 10 watt that's different man. U've understood Ohm's Law but why u still asking for that question. Iam not angry but I just want to say something stupid...

vule · 09-29-2003, 14:02

In addition to my previous post...

Just 2hrs ago i flashed 3510i to add language...By mistake i put that sim in phone in order to check and change to desired language.
Phone powered up with blank screen then turned off...I tried again with no succes. I had to flash it again to made it working...

So, i checked again with that sim...And same situation again, but just if i put that particular card after flashing. If i power up phone with some other card, power it off and then put that one " no sim card "...

If i put that one in N3310 works ok but ccont gets really hot. In T10 ericsson i can't see any problem...All other phones " no sim card "...

Funny...That sim is really cool...

@willy.....

Would U explain in some detailes how to check for compleet
diagnosis by useing Wintesla , this problem??. Also to differentiate between SIM and phone problems?.
Really apreciated to U man ................ Thx
