Black Solution: Through the informal channel, the violation of the activation strategy, the official discovery by Apple will change back to the original lock strategy, called the Black Solution, and then locked. Let's take a look at a U.S. att version of I6 after the formal official solution of the strategy is what it looks like:
For example, the next activation strategy is 2303-multi-mode unlock, the formal official solution of the lock-free strategy. After unlocking the machine to activate once, the application policy will be enabled no lock policy, just unlock success, but not activated see, has been unlocked that or false, does not matter, see next strategy can, 2303-multi-mode unlock:
Below to do a schematic, unlock before and after the activation policy changes at a glance, the next activation strategy of the formal official solution to be connected to the 2303-multi-mode unlock, the re-brush upgrade is also always unlocked:
However, what is the case of the black solution? See:
Is the black of the ATT (by the way, also do not know which brain remnants incredibly att also go to black solution, ATT's permanent unlock is not expensive ah, black solution generally appear in the U.S. blacklist T-mobile and Japanese version of the machine), found that the current application strategy is 2298 of China Open distribution Unlocked policy does not have a locking strategy, but the next strategy is already a 23-att locking strategy. Its activation policy changes roughly as follows: Shiman:
Initial strategy: 23-us
Application strategy: 23-us
Next strategy: 23-us
23-us
23-us Not activated after unlocking:
Initial strategy: 23-us
Application strategy: 23-us
Next strategy: 2298-china Open distribution n61/n56 Unlocked policy
23-us
23-us
23-us After unlocking and activating the use:
Initial strategy: 23-us
Application strategy: 2298-china Open distribution n61/n56 Unlocked policy
Next strategy: 23-us
23-us
23-us The current application policy is 2298 no lock policy can be used normally, but a brush machine recovery, the current application policy is invalid, start to enable the next policy, waiting for access to lock policy, this is locked! Official permanent lock-free activation strategy is not only 2303-multi-mode unlock, there are 10-unlock (Sprint official solution will not appear under the 6 Unlock,att) and so on. But one thing is clear, such as clearly the Japanese version of the mobile phone, unlocked after the discovery activation strategy is another country's lock-free strategy, this is the black solution, will be locked. The black solution includes, but does not limit, what happens above. In fact, to verify is not permanent official solution, after unlocking a few more activations, and then wait a few days to check the activation strategy can be seen. Not the official solution, the next activation strategy will change ~
In addition to the query strategy, the most effective detection is the official solution is: Official solution can be casually brush machine, recovery, erasure, upgrade!!! Black solution can NOT!!! This article is reproduced, non-original, the purpose is only for everyone to exchange learning! |
