We know unlocking can be confusing ...
at UNLOCK.IMEI.INFO we believe in sharing our knowledge to raise anybody to an Expert Level !
Since our last update v18.104.22.168 we unlock most Samsung without having to ROOT them. To check if your model of Samsung is supported without ROOT, please check our list of supported models here: http://unlock.imei.info/software-unlock/supported-models/#samsung. If you don't see the TAG "Root" / "Unroot" next to the model of your device then this mean we do Direct Unlock without Rooting. However in the situation we do the root please note it will be a Temporary Root exploit that we will close after unlock.
Yes, it’s 100% permanent Unlock, once you unlock your phone with our solution you can do whatever you like (Upgrade or Downgrade Firmware, or even install custom firmware like Cyanogen or Avatar). Your phone will remain unlocked no matter what, for life !
Since the 2nd August 2016 (v22.214.171.124) we do offer a 100% Brand Free version of our Software for all our dealers.

To download the last version of our software and driver, please go to this URL:
Unfortunately we only unlock GSM phones, we do not unlock CDMA version from Sprint, BoostMobile, StraightTalk, or Verizon… It’s very important to always invest in GSM Phone whenever possible, especially if you are an international traveler to ensure you can use it worldwide. CDMA is a standard that only work with some networks from the USA, and Japan.
Unfortunately this means our software cannot Auto Root your phone at the moment. You can still manually root your phone with third party software (Like PingPong, iRoot, or KingoRoot) and then use our software to Unlock It. However we cannot provide support for these Third Party rooting software so if you prefer to give up or if it’s too technical for you then please contact us by email and we will Void the license and refund your transaction.
All Samsung listed in the update v126.96.36.199 (see our change log) are supported no matter the version of your firmware, but as long as not using the "Device Unlock App" (MetroPCS & T-Mobile USA Only)
For any other Samsung Cell Phone, unfortunately these are not supported by our method, however it's possible to downgrade your phone.
We recommend you to downgrade your phone BEFORE ordering your license, as we do not provide support for downgrading.
Since it's permanent unlock, after unlocking you'll be able to upgrade your phone again to the latest version of Android !
