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 = 18 in the example above so X = 8]
[if the sum is 3, X = 3]
[if the sum is 17, X = 7]
[if the sum is 25, X = 5] etc.
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
