When I get the phone into my hands it had a strange problem: when you turn on the phone it always says "SIM error" even when any sim card was inserted on the phone. So, I suppose that was a reflash problem, that maybe someone put his hands over the phone before an get this faulty result.
So I turn on the phone, then I connect the phone to PAPUAS v0.9.6, an click "Information". It shows that the phone was in factory mode so I click on the "Read Codes", I get ESN and HASH. Then I click on "Calculate SKEY and BKEY", all ok. Then go to service mode an click on "Mastercode", all code were calculated ok. Then click on "Release SKEY" and with the phone on introduce the unlock keys. The phone continues with the same error.
A day latter I turn on the phone an click on "Information", I always get some wrong information so I did it again until PAPUAS shows an EXIT error and the phone go off. I try to "Read Codes" a couple time but I get the same error, also I get 2 different HASH & ESN pair whit PAPUAS v0.9.6 and v0.9.5b. I continue doing this until I get the phone DEAD!!!!!
Thats all explanation my experimented friends. Maybe you can get a better idea of what it's happening now an give me the correct assistance.
