E51 ahus chip

[gsmgsa]

Hi everyone!

E51 no network. AHUS rf chip is faulty.

So I replaced the chip and then phone starts with black screen, lcd light on, keypad light on, then flickers few times then shuts down.

I removed the chip off the board, turned phone on and phone's start-up white led only lights, no light on LCD screen this time, nothing; and white led remains on.

It seems after replacing RF processor, there's a need for some software solution.

Please advise!

Thanks in advance.

Without RF ic phone will not power on reball and solder back make small balls possible first time they short or you give less heat and it not solder completely.
