Unlocking and Activation of Apple ID Lock
Activation lock is also a difficult problem in the current maintenance industry. It can't be solved by soft solutions such as software and computer. The only feasible solution is hardware decoding. At present, only iPhone 5 can realize hardware decoding activation lock. The principle is simple. The locking basis of the activation lock is the IMEI and SN code of the machine itself. If these two codes can be replaced, they can be unlocked naturally. Let's take a look at the specific maintenance process:
1. Disassemble the machine and take out the motherboard.
2. What needs to be replaced are baseband chips and baseband fonts. Remove the shield with an air gun first, and then remove the chip.
3. Put the baseband chip and baseband font back on the motherboard.
4. Write the available IMEI and SN codes into the newly installed baseband chip and baseband font. At this time, professional numbering staff and software are needed.
5. After the above operations are completed, install the motherboard for testing and startup. Apple ID and password are not required for activation at this time.
