As We know that Power amplier can not be jumpered.. because then it will not amplify (boost) the power transmitted.

We technicain knows that jumper is only last solution when ic's are not available in market. if any one have replacement of component then he is not advised to jumper
espacially to amplifiers like audio or RF power ammplifiers.PA

this jumper will give you two limited benefits

1. It is pointing us to fault and It will remove our cell phone shortage when we will remove this ic
2. It will show service on some simcards / operator / mostly near to booster etc
. Telenor Pakistan is tested by me. In your case may be other one, So change sims which ever is your luck.

please read my post care fully

it is last option when you asure that 6625 RDA is damaged and no replacement of of found, then jumper and found low signal and registered on some network.
if you found no signal that may be your problem is some where else in the circuit.
mostly the circuits become short in this model caused by RDA 6625 shortage, are repaired to replace the ic or jumper like this and get low signals.
May be in your case due to shortage of this ic some where els this circuit is damaged . and this can be checked only by the technicaian have the mobile phone in his hand. So advised to check other hardware also

thanks to you all by gsmzaman
