The 20 digit are NOT supported currently. Please, when you add hash, you must be absolutely sure that it is 15 digit SL3 locked, otherwise after the bruteforce attack we use, no code will be found and you will loose your credits. We also don't accept Telcel Mexico locked phones. This operator manipulates the hash of the phone and even though unlock code is generated, that code will not be accepted by the phone. Tools like Infinity Best recognize those phones, so please don't upload them.
