Unlock iOS 6.1.2 iPhone 5 / 4S / 4 Using SAM, Ultrasn0w, Gevey SIM

We've already given you the download links and jailbreak guide for the latest iOS firmware; iOS 6.1.2. Today, we are going to cover iOS 6.1.2 unlocking and basebands review for Apple's latest OS offering.

We're going to cover all unlocking methods that have been released till now, which include SAM unlock, Gevey SIM, ultrasn0w and not to forget, the IMEI factory unlock solution for iOS 6.1.2 devices.

iOS 6.1.2 basebands on iPhone 5, 4S, 3GS and iPhone 4

Many of you may be aware, but those who aren't, they should know the baseband gets updated along with firmware updates. However, iPhone 3GS, 4 and 4S users get to keep older basebands by creating a custom firmware. Here's the complete iOS 6.1.2 basebands list:

  • iPhone 5 - baseband 03.04.25
  • iPhone 4S - baseband 3.4.01
  • iPhone 3GS - baseband 05.16.08
  • iPhone 4 - baseband 4.12.05

How to Unlock iOS 6.1.2 with Ultrasn0w 1.2.8

Ultrasn0w unlockers can use ultrasn0w 1.2.8 to unlock iOS 6.1.2. To do so, the baseband needs to be preserved with custom firmware. For more details, you can check out our official utlrasn0w 1.2.8 tutorial.

Unlock iOS 6.1.2 Using R-SIM 7 / 6, Gevey SIM or X-SIM

We haven't so great news for Gevery SIM, X-SIM and R-SIM users as they can't unlock on the latest firmware, and if they update, the device is going to get re-locked. If you are user with 4.10.01 baseband you can preserve the baseband and update to iOS 6.1.2 to get working Gevey sim on your iPhone 4. If you're one of those who rely on this unlock, keep far away from the iOS 6.1.2 update.

Permanent IMEI Unlock iOS 6.1.2 iPhone 5, 4S, 3SG or 4 via IMEI code

Unlock iOS 6.1.2 Using SAM Unlock Tickets

Sam unlock users who have saved activation tickets have hope. Users with saved tickets can unlock the device on iOS 6.1.2 at any moment. If there's no ticket saved, the device shouldn't be updated to latest firmwares. iPhone 3GS, 4 and 4S users can follow our guide to untethered jailbreak iOS 6.1.2 firmware and restore the SAM unlock tickets.

Factory Unlock iOS 6.1.2 iPhone 5, 4, 3GS, or via IMEI Code

Out of all the unlocking methods that we've highlight so far, factory unlock is the best method for iOS 6.1.2. This IMEI-based solution is permanent, and sweats of re-locking no longer worry the users. Furthermore, the device can be updated to latest firmwares and basebands, as the IMEI is saved in Apple's database.

There are many services that claim to provide this same service, but our recommendation is the most reliable and affordable. They can unlock AT&T, Sprint, Rogers, Vodafone, Fido, O2, Orange and other famous carriers in the world on all iOS firmwares including iOS 6.1.2, 6.1.1, 6.1, 6.0 and below. For getting your phone unlocked forever, go here.

So how do we unlock iPhone 4S - baseband 3.4.01?


sam perftctly working for me on iphone 4 ios 6.1.2 bb 4.12.05


how pls can ya tell us what did you do ?


i have iPhone 4 running on iOS 5.0.1 with BB 03.10.01 and using Gevey Ultra SIM. If i upgrade to iOS 6.x.x and preserve my current baseband - will this work with Gevey Ultra SIM? Offical Gevey page says that it does not work but has anyone tested this?!


Will Gevey SIM work with preserving the baseband on 03.10.01?


You must folow this steps:

1- Create a custom 6.1.2 firmware using snowbreez, General option ,UNcheck (Important) Hacktivation, and check the "Install SHH" option.

2- When you have your firmware on the desktop , put your iphone in powned DFU mode , and restore with Itunes

3- When the iphone reboots , you will have the welcome screen, but since it's not an official sim card, it's not actvated, dont worry , just connect your phone by cable and use Ifunbox ot iTools and put your Lockdown folder in it's place.

4- Reboot your iphone, it will restart and you will have your signal and without need to hacktivate


Yeah... same problem here, any help will be appreciated!!!!!!!!

Mohd Mehr

can i unlock my iphone 5 , ios 6, AT & T carrier locked and reported stolen, what can i do now ?


I want to upgrade ios from 5.1.1 to 6.1.2 and have baseband (modem firmware 2.0.12) at present.

So how do I upgrade to 6.1.2 without updating baseband or preserving to same baseband.

I tried to preserve baseband by using redsn0w but its not accepting IPSW file.

So is there any way to preserve baseband? or I should upgrade the ios. And is it possible to unlock using cydia. I want it to jailbreak with evasi0n 1.5.

please guide me how to unlock it if once upgraded and jailbroken..

i have backed up tickets using redsn0w and also done on Cookie app from cydia.

or is there any ipsw available for 4s without baseband upgradation.

one more thing, that I dont have original sim but got the ticket from redsn0w with the unofficial sim. my device is already jailbroken and am not on ultrasn0w, and dont have any idea how my unofficial sim is working on it.


Thx M. Khalid, it worked i have signals all seems ok, but Itunes does not recognise my iphone and i can't restore my back up,
Any idea??

Francis Floresca✌❤ ♫

I tried this but when I connected my iP4 to iTunes to do a restore backup it says "itunes could not connect to the iphone because an invalid response was received from the device". Will you please help me on how to fix this one?


iphone 4, 4S or 5?? no baseband preservation available for ip 4S n upwards...


Try this:
-Click Start , in the search bar type "services.msc", and click enter , look for "Apple Mobile Device" right click , and choose "stope " then , right click again , and choose "Start" . Itune will connect again to your device.


2.0.12 baseband can't be preserved. if you are gevey sim user don't update to iOS 6.1.2.


tanx for solution , i have iphone 4 lock basband 4.10.4 . i can update to 6.1.2 with snowbreez 2.9.11 and unlock it with Gevey ultra ...

I found your posting that after unlocking your iPhone with Sam it was not working.I am facing the same issue. Did you found any solution to the issue.thanks


This is too expensive; 89 GBP for Tele2 unlock! You need to do a discount there!


Yes, it works with any verizon device & ios firmware / baseband.


@5c28fe22ad7c995fafb35ac273a7c20f:disqus The networks set the unlock prices, not ourselves unfortunately, this is the main reason why some unlocks are more than others.
