I got so damn tired of my HP840 that i took the LG 4166 1.02 RPC 1 from The Dangerous Brothers and fixed it to flash on HP840.
Go grap : ftp://hp840:firstname.lastname@example.org/tom
You'll get all features of V1.02 and RPC1
So you only patched the ID in the package??
Use ftp://hp840:email@example.com/ only. Testet that with my mobile phone. The other link somehow doesn't work.
