I've bought a code to unlock my Galaxy S II GT-I9100, and it didn't work. The seller was kind enough to refund me, but my problem is still not solved.
Some things to consider:
- I don't have a rooted phone, or any interest on rooting it.
- I've already gone to my Service Provider (Vodafone Portugal) and they asked for an absurd amount of money to do the job.
So, I'm reluctant in buying another code from ebay since the problem may still be there.
One seller says this:
"With the correct SIM card inserted type *#7465625# into the keypad, you will then be presented with a personalization screen similar to the following. If after entering the above code you get an "Invalid MMI code" error message do not buy this service. Your phones firmare may have corrupt data and may reject the code, reinstall the firmware using Samsung KIES and check you no longer get the error message before ordering"
I get the Invalid MMI code.
I've tried to reinstall the firmware using KIES, but it says 'GT-i9100 does not support initialising'.
I've made a factory reset and still get the Invalid MMI code.
TL;DR Can you help me unlock my phone?
Thank you all in advance!
Steps to fix:
- I used this guide to root the phone (If you have your phone already rooted, forget this.)
- Install this app and it's done! (Thanks to marjune23!)
