To find your SIM UNLOCK CODE you need: 1) Root 2) Android Terminal Emulator (free from the market) 3) Your IMEI number (dial *#06# on your dialler) There are 4 steps to the process: 1) Obtain your UN_lock_code from your phone 2) Calculate the key from your IMEI number 3) Subtract (2) from (1) 4) Unlock your phone Step 1 Obtain your UN_lock_code from your phone as follows: Open the Terminal Emulator app and type: su [enter] strings -n 8 /dev/block/mmcblk0p6 [enter] It will output several lines of data (including your IMEI number) One of the lines will be [eg] UN_Lock_code=063312345 Make a note of this number ( This is NOT your SIM unlock code )! Step 2 Make a key from your IMEI number: a) Write down the last 7 digits of your IMEI number in this format: 1234 567 b) Reverse the 2 blocks: 567 1234 c) Add a 4th digit X: 567 X 1234 where: X = the sum of the first 3 digits (If the sum is 2 digits, write only the 2nd digit) [ 5 + 6 + 7 = 1 8 in the example above so X = 8 ] [if the sum is 3 , X = 3 ] [if the sum is 1 7 , X = 7 ] [if the sum is 2 5 , X = 5 ] etc. Using the above IMEI number we get: 567 8 1234 (= the key) Step 3 Perform a simple sum. UN_Lock_code [step 1] – k e y [step 2] = SIM UNLOCK CODE eg 063312345 - 567 8 1234 = 6 531 111 This needs to be an 8-digit number, so add a zero at the beginning if necessary YOUR SIM UNLOCK CODE IS: 0653 1111 Step 4 Unlock your phone a) Remove your SIM card (no need to turn off the phone) b) Insert alternate SIM card c) When prompted, enter SIM UNLOCK CODE obtained from step 3 d) Reboot when instructed na polski
