I have a router WNR834B with chipsets BCM4704 KPBG and BCM5325 FKQMG. Problem is that there is failed flash 29LV320. I need full image of 4M flash or only bootloader from this model. I want to program  flash with usage of  external  programmer. Please send me this image for an email: sbuli@poczta.onet.pl
Best regards.
