Baseband Unlock Iphone
Baseband Unlock Iphone
generally, the baseband will work fine from the factory, no additional actions are required on the part of the end-user. if the baseband does become corrupt for some reason, it is simply a matter of a simple update. (apple has to approve this update, of course, and it takes a bit of effort.)
also, following this procedure means that the iphone will only work with the sim that was used during the unlock process. if you intend on using multiple sim cards with the unlocked iphone then the process will need to be repeated with each sim on an individual basis. the team involved in producing this unlock have also recommended it as good practice to make a manual save of each ticket that is generated due to the fact that it could prove crucial going forward.
at +0x400 in the seczone, a token is stored encrypted with (nck + norid + hwid). apple, knowing the nck, sends it using an activation token over itunes. the phone receives an at+clck=pn,0,..nck. it decrypts the token with the generated key. if that decryption, after dersaing with key 2, is a valid token for the phone, it is stored back to that flash with the token tea, but not rsa decrypted. on startup, if the lockstate table says the phone is unlocked, it validates that rsa token.
unlocked iphones do not come as cheap as a new iphone. the prices range from around $330 – $425 for most carriers. apple is known for keeping the price of the iphone very low due to the fact that they cover the expenses themselves.
the baseband is the modem that lets the phone connect to the cellular network using the sim card on the phone. this means that for every carrier the phone will need to use, if unlocked, a different sim card to have it work. unlocked phones allow you to use more than one carrier, yet they can only be unlocked through the carrier for their network.
additionally, we now have a better understanding of some of the limitations of the secure enclave chip, with knowledge of the ability to access and work with analog sensor information allowing for the unlocking of many iphones.
however, just because you can jailbreak an iphone now, doesnt mean that it doesnt still require unlocking in order to function as intended by apple. jailbreaking just opens the door for the easiest route of attempting to unlock the iphone, but it certainly isnt enough if your goal is to have an unlockable iphone.
hence, some jailbreakers like to automate these processes and attempt to at least get a good idea of whether or not the baseband can be unlocked. if it can be, then we just need to see if there is a way to work within the limitations of the current jailbreak.
while this news has the possibility to be a huge game changer, i’m sure we’ll hear more on this as time goes by, and the process to unlock your iphone becomes a little bit more automated and streamlined. as a disclaimer i have a pretty solid understanding of ios 5.x/6.x since i have an iphone 4s and a 4.
once you have removed the baseband from the ipsw, you still need to jailbreak the iphone. once again, i highly recommend using redsn0w (since ive been testing all the devices for you) on a 32-bit ios5 device. if you havent ran redsn0w in a while, you might want to try reinstalling the redsn0w.app file. installing redsn0w from the app store is usually not a good idea.
once you’ve updated your firmware, you still need to jailbreak it. you can use either cydia impactor or redsn0w. i recommend redsn0w since it is more user friendly. personally i prefer it to cydia, but the choice is up to you.
