So I have my HTC One here, rooted, bootloader unlocked, installed Cyanogenmod 11, but it is SIMLOCKED.

I tried T-mobile support, and out of three times that I requested the unlock code from them they only sent me the unlock code once AND IT FAILED

I tried the Ultimate Simlock Code Generator 2.1 and it just didn't respond after I complete the survey before it is supposed to give me the download link.

I tried to find the UN_lock_code with this method from another thread:

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 = 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.

Using the above IMEI number we get:

567 8 1234 (= the key)

Step 3

Perform a simple sum.

UN_Lock_code [step 1] – key [step 2] = SIM UNLOCK CODE

e.g. 063312345 - 56781234 = 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

I looked up everywhere else and the rest of the internet just told me to pay to unlock from some random apps on Google Play Store.

I am in Taiwan now so some of the T-Mobile support pages aren't even reachable (error 500), not to mention going to a T-Mobile store.

So what is my best bet now? Is it because I have Cyanogenmod 11? Are there any other ways to unlock the simlock? Or should I just pay for it and get over with this quickly?

Thank you in advance!!
