Hi All,

I am having SE K790i. I flashed it to K810i. It was fine but with the problem that it always show NO NETWORK COVERAGE after inserting the sim card.

Finally I downloaded the files K790_R1KG001_FS_CENT_EUROPE_RED52 and K790_R1KG001_MAIN_GENERIC_EV_RED52 and flashed it back...

Still I have the same problem of NO NETWORK COVERAGE and accompaning that my handset speaker gives a cracking sound!

I used XS++ 3.1 for all flashing.

Do any one has something to share?? When I went to certified Sony Service Center they said due to some liquid your motherboard of the mobile is damaged.

I would highly appreciate if anybody can help!!

And Many Thanks in advance!!
