Hello friend, the two bigger ones (black) are coils, don't remove these if continuity!

Please inspect C49_RF, C14_RF, C26_RF, C76_RF, C83_RF, C92_RF, C90_RF, C98_RF, C101_RF, C97_RF, C100_RF, C96_RF and C99_RF as to why VSD2_1V8 is short, look for water damage!
And please inspect C50_RF and C7_RF to finde why VSD1_VAR is short.

Use microscope to inspect. When water damaged cap found, remove with hot air or alloy and solder iron!

Good luck.
Jon.

Edit: references to the caps I am talking about can be found here http://forum.gsmhosting.com/vbb/f631...ginal-1492362/
Don't forget to thank mr. Wites for his great work!

The L2_RF and L3_RF have continuity but both ends of coils is shorted that is not good....
i will check C49_RF, C14_RF, C26_RF, C76_RF, C83_RF, C92_RF, C90_RF, C98_RF, C101_RF, C97_RF, C100_RF, C96_RF and C99_RF as to why VSD2_1V8 is short, look for water damage! as you was said when i arrive to work .... in a couple of hours
Edit: Coult be shorted from baseband chip ?

For me this was caused by a short in the balls of the BB CPU..It has happened to me the same thing.

It looks like you will need to reball U9_RF
