-= 7610 help please (looking for alternate points)... - GSM-Forum

KaBLooMz · 05-25-2007, 17:58

Hi All,

I am repairing a 7610 "Phone start-up failure. Contact Retailer...."

I removed the IC in attached pic but, I may have lifted a few points off during the removal and was wondering if any of you may know where the alternate points are ...

I have attached a pic with the points in question circled in red.

I want to find the alternate points to retrace the SIM connectors to see if this would fix the failure listed above...

Thanks in advance for all of your help!

if u damage the in put track then u have only one alternative i.e; direct connection from uem.if out then u can easily take jumper from input to sim tray.

your phone problem is user flash you change user flash ( Ks86xxx flash code) and than software update. %100 solution

Man your phone problem is not with the's IC maybe it's software just erase ur phone then flash it full flash and format user area
if the problem still change ur IC flash

Actually, I wrote down the wrong message. It said "Insert Sim" even when sim is inserted.

Lolz, I have 2 7610's I am working on at the same time. One says "Insert Sim", this is the one where I need the points retrace.

The other one with the contact retailer, i think my only option is to replace UEM (for which I don't think I can do yet).

Again the question is, does anyone know the alternate point's in the attached diagram. Thanks!

Anyone?!? Am I the only one that messed up the tracks so badly?

xtremeburaq · 05-27-2007, 08:18

U Donnot Need To Replace Uem Just Check Which Prints Are Missing.then Take Out Connection From Uem With The Help Of Jumper Wire.( Condition If Input Track Are Damaged ).

Try To Change Boot Ic. ( Contact Retailer ).

@xtremeburaq

so do u know the points I need to jumper off of the UEM? How do I know what connections to use as alternate points.

I don't have boot IC to change... I just remove the IC and follow the jumpers to similar diagram.

bump.... anyone got these alternate points????

You should be able to find them with a voltmeter set to "buzz thru" (buzz for < 100 ohm resistance). You can set one lead to the track in question and poke around other vias and connections until you get a buzz meaning you found a short and anything along this track/connection is an alternative connection.

by the way have you been able to figure out how to fix the "insert sim card" problem even tho a sim card is inserted? I have the same problem ever since I dropped the phone into water.

Also would you know how to retrieve info from internal memory without a sim card present? I'm trying to either fix the phone or just to power it on and get all the stuff out of the memory so I can save my contact list, etc.
