C75 unlocking step by step:)

  • Thread starter Thread starter szmit4
  • Start date Start date
1. connect gnd to testpoint like c65 (USE RESISTOR FOR TESTPOINT CONESTION)
2. run x65papuautil newer version and go to Flash men
 
ad calculate codes
flasher tab check change mastercode press readand power on the phone wait some seconds. in log windows u see all mastercodes for this phone is resetting to

12345678

ex *#0000*12345678# without sim and phone will be unlocked too.

when u entered and opened skey in the phone u have many way to unlock any siemens for ex. cx70 c75 all version of coz. for example (freia) have options save log and create map from log etc papua have save log but if u cancel now save log options u see small windows confirm 'save blocks directly to the phone? and choose yes and power on the phone and thats it any phone is unlocked ;-)

ad 6 u see we not need epromtool for unl.

works on any wersion and model if u entered and opened skey via java or via tp or without if version lover than 36

Hi all
I want to unlock C75 v11 like this (described by thread-starter), I'm using TP, Papua_0.5.1.
everything is ok, but at least I got this error massege while i want to save selected number in Eeprom tool:
error?15( ..) while writing block 5008?
I tried by szmit4 method (without eeprom tool, directly) and I got same error.

Setze ServiceKey (Skey) im Handy...

this step do it on powered phone and without sim. correct answer is factory mode not customer
 
For all in this post!

when you have C76 VER 11 or over use this method when not don't post nothing finde the pachv4 in other post and have fun.
This is my worked solution and I write all exactly so read it most slowly.
This not a new metod just a usable for this f***ed siemens C75.
When you make it for first time don't loose your time go and read all post in siemens x65 and x75.
Thx.
