7610 problem - GSM-Forum

DmitriK82 · 06-04-2007, 08:59

Phone was dropped into salt water, after treating it with denaturated alcohol and drying it, it starts fine but even with sim card installed it says "insert sim card". Also right part of the keypad, or actually 3,6,9,# keys do not work so I can not do a reset because I need the # sign for it. Can anyone suggest:

1. How to download the address book from the phone and save other personal info if I need to replace the phone?
2. How to fix it? If I need to flash the phone, how do I flash it and where to get the software?
3. Why don't those keys work?

I tried to figure out why keys don't work. Which pins, if more than 2, on the connector are responsible for the 3,6,9,#? I tried to do the buzz check with a voltmeter to find which pins are shorted when for example 3 is pressed; those 2 pins look ok. Manually shorting them with a wire doesn't produce a '3' on the screen either so it must be a bad/shorted connection elsewhere. Any suggestions how to troubleshoot this?

I'm fairly new to the whole phone terminology and have no idea what jaf, etc are. I read some previous posts. Please do not assume I know anything. I'm very new to this.

Thank you for your time.

bro, try to reheat kpad ic and simcard ic...or its better to place it w/ new ic..no need of reseting it..

Hmm, I think I know which IC is the simcard IC, but where is the keypad IC? I downloaded the zip with pictures and only found the simcard IC (R310 is the simcard one right? Although prefix R should mean it's a resistor pack...weird)
