Funny thread i must say. The man have posted all under solution 2, he found that data somewhere on net, wikipedia most likely hehe and even after he wrote all needed steps to repair this other person say to us that he found solution on other site.

Bulshitzzz

Solution is here under post#2 but only what one need is little technital knowledge and some tools to repair.

If u have no tools then take unit to service centre, people need to make a living out of something.

Thanks.

Manully search kar k dekho

U need to categorize problems notchange all parts...

1st write latest mcu ,PPM; then write good Pm file.
If OK, otherwise go to 2nd step{Search networks manually ,if it shows all networks, then fault and cannot register then its fault of gsm,dcs,pcs amp...IF it does not search any network then ist you reflow PA and also make ant.sw jumper..
Now cheque the network. If it is O.K. Otherwise Filters, c&L&R..

there are two sections in network: 1, Rx section. 2, Tx section. all bros plz use manual searching in mobile phone, testing for Rx section and Tx section.
HOW TO FIND WHICH SECTION IS FAULT Tx (or) Rx?
Testing Rx section
use manual search for Testing Rx section, after searching Rx section good condition means it shows network list like Airtel, hutch, (or) any other network list in your area,
If Rx section bad condition after searching it shows NO NETWORK FOUND
1, after searching it shows network list means Rx section is ok.
2, after searching it shows NO NETWORK FOUND or some networks missing means Rx section is faulty.
Testing Tx section
Use manual search for testing Tx section, after searching it shows network list, then you can choose your simcard network, if Tx section is good condition it shows HOME NETWORK SELECTED, if Tx section is fault it shows NO ACCESS.
1, after selecting network it shows HOME NETWORK SELECTED means Tx section is ok.
2, after selected network it shows NO ACCESS means Tx section is fault.
