How To Permanently Carrier Unlock Galaxy S III & Galaxy Note II For Free (Guide)

Brought to you by TronicsCity.Com  Your #1 Source Of Smartphone Unlocking.

One of the biggest hindrances with buying a top-of-the-line smartphone, is the premium price that you have to pay for it. There are usually two ways of how high-end phones are sold; either you pay the full price to the manufacturer and get an unlocked device, whereby getting the freedom to go with whatever network fancies you. Or, you may opt to buy the phone through a wireless carrier, where you pay a much subsidized rate for a big trade-off: getting stuck with that carrier for the term of your contract. In the latter case, the carrier pays the full price to the manufacturer but sells you the device at a much lower rate, and in turn, locks down the smartphone to their network, so you cannot use a SIM card from another network just like that. That’s a generally agreeable rule for most users.

However, there might be cases when you don’t want to remain stuck with the same cellular service provided, especially if there services aren’t satisfactory. There might also be times where you want to travel abroad, want roaming, but don’t want a local carrier that’s partnered to the one you’re subscribed to. Still others might be times when you just want to unlock your phone. Now, these phones are locked via software code, not at the hardware level, so there’s always a good chance that a good device tinkerer will be able to unlock it and let you get a job done for free that would otherwise cause your wallet to go lighter, even if marginally. Well, if you happen to own a Galaxy Note II, or a Galaxy S III, you might be able to network unlock your Android smartphone entirely free of cost!

How to Unlock Galaxy S4 Free 

The method comes courtesy of the folks over at XDA-Developers, who uncovered a hidden menu buried deep in Samsung’s own software that lets you unlock a pre-locked device. There are some factors to consider before attempting this, however. One, it will work ONLY on locked devices – we don’t know what might happen if you try that on an already-unlocked Galaxy Note II. Two, this method has been tested with only N7105 for the Note II, and while it has been reported to work for the N7100 and some Galaxy S III models, they’re not guaranteed. Three, meddling with these areas of your phone is seriously risky business, so proceed at your own risk.

Please note that these instructions will only work if you’re running Android 4.1 or higher.

Procedure

Step 1: On your Galaxy Note II, launch the phone app and press these keys:
*#197328640#

Step 2: From the Main Menu, navigate to [1] UMTS > [1]Debug Screen > [8] Phone Control > [6] Network Lock > Options.

Step 3: In the Options screen, choose [3] Perso SHA256 OFF. Wait for 30 seconds after making this selection.

Step 4: Go back one step by pressing the menu key, and then back once. You should now again be in [6] Network Lock

Step 5: Here, now choose [4]NW Lock NV Data INITIALLIZ. Wait for one minute after making the choice.

Step 6: After a minute has passed, reboot your Galaxy Note II.

Your phone should now be unlocked, and ready for use with any carrier. Please note that you will NOT receive any sort of confirmation on the screen, so just put in a different carrier’s SIM and try it out.

How To SIM Unlock Samsung Galaxy S4 GT-I9505 For Free

Brought to you by TronicsCity.Com  Your #1 Source Of Smartphone Unlocking.

Having a network locked device can really hamper how you use it, especially if the network isn’t of your choice. While most of the times, the operator in question would let you unlock your device for a small fee, not everyone might be that lucky. Imagine a scenario where you’re travelling abroad and want to use another network’s SIM card, only to discover that you cannot thanks to a carrier lock. Unlocking can really save you from quite a few hassles and tight spots.

As a rule, you can get almost any device unlocked by paying a small fee directly to the carrier, or to several online services that would let you purchase an IMEI unlock. However, in my personal experience, nothing beats the feeling of doing such a process yourself, and save those precious bucks in the process. Samsung, generally, has been more relaxed towards letting its users carry out a network/SIM unlock on their devices on their own, provided they knew the right steps to follow. Earlier, we brought you a tutorial on how to carrier unlock Samsung Galaxy S III and Galaxy Note II fairly easily without any specialized tool. Today, we’ll guide you through unlocking of the new flagship from Sammy, Galaxy S4 GT-I9505.

Before we proceed, please be advised that the usual disclaimer applies. Playing around the carrier lock is risky business, and more complicated than your average Android modding. Follow these instructions at your own perusal. Redmond Pie cannot be held liable for any loss whatsoever resulting from following this method. Also, this method applies to GT-I9505 only, and not to other variants of Galaxy S4.

Step 1: Launch the Phone app on your Galaxy S4, and dial in: *#0011#

Step 2: Press the Menu button followed by the Back key. Then, hit the Menu button again and select KEY INPUT. Enter 1 and press the OK button to enter ServiceMode.

Step 3: Press Menu one more time and tap back again. This will pull up the Main Menu forServiceMode. Tap [1] UMTS.

Step 4: Now select [1]DEBUG SCREEN, followed by [6] PHONE CONTROL.

Step 5: From the next screen, pick [6] NETWORK LOCK.

Step 6: You’ll get three options. Hit the one that says [3] PERSO SHA256 OFF.

Step 7: Now, you need to get back to Main Menu. To do this, hit the Menu button followed by the Back key. In Main Menu, now pick [6]COMMON, and then [6] NV REBUILD.

Step 8: The phone will tell you that a Golden Backup exists. Tap [4] Restore Back-up.

Your device will now go through a series of “conditions”, where it will first freeze, then get on a black screen with Blue LED on and both capacitive buttons on, after which it will reboot automatically. The whole cycle might take a couple of minutes, so be patient. Once it powers back on, it’s network unlocked, permanently. Enjoy!
