Simple, remove bkey code on BKEY column on Code tab, then, do all process again..



Only one doubt..What cable you using? I had this problem too, but im was using dca-500, and a driver for increase COM port speed..I always get this error msg, and my bkey was OK...I solve it removing the driver installed(serialxp), and installing other driver that increase COM port speed(HiSerial Driver)..After this all is ok..Verify if it is ur problem..

Regards.
 
szmit4 what do u mean Calculate master key how can we do that and unlock
PLZ tell step by step how ca we do that.....And as u said above
"ad 6 if u choose no log is saved papuas unlock ur siemens directly"
What does this mean it unlock direct o need of mapper or Eeprom tool...And is it gona work on cx70 v43 as well and similer mobile versions???
 
I present more simply way with TP
1. Connect testpoint to ground wia resistor (approx 40 ohms)
2. Go to flash, select pause
3. Press start and quickly connect power on contact to ground (I do this with tweezer)
4. When soft display - pause 2 sec., remove TP
5. When all codes is displayed, go to CODES and press CALC SKEY+BKEY, after HASH+BKEY, after power on the phone and press SENd SKEY TO PHONE
6. Than go to SETTINGS and switch phone in service mode
7. Go to DIFFERENT and press READ IMEI FROM PHONE
8. After press 5008 phone code
9. When displayed question press YES
10. Go to SETTINGS and press POWER OFF THE PHONE
11. Drink beer after sucesfully unlocked phone

If you want make unlock cable for unlocking with TP and non TP methods, contact me

I unlock C75 sw.11 and cx70 sw.43 with this method:
1. connect tp (c65 tp) and run x65PapuaUtilsV051_DE
with ''ersetze blocke 76,5008,5009,5077'' and ''pause'' checked
and start - pause 2 sec discconect tp - SKEY+BKEY - HASH+BKEY - power on
phone - send SKEY and phone unlocked
without use siemens eeprom tool and freia log and map.
 
I confirmed c75 v.11 can be unlocked without testpoint via java patching,just now i unlocked one.
 
lately I unlocked c75 version 11 without testpoint and all is ok,but now with this another c75 ver.22 i already did the testpoint and it goes smoothly but no codes extracted.what should be the problem.
