How To Unlock iCloud Lock 4 digit / 6 digit With HDBox


In this short how-to you will learn how to remove any iCloud lock from a mac computer in just a few minutes using our HDBOX interface with HDBOX ISP-SPI Adaptors and Apple EFI app installed on your HDBOX.






1) Check our list of known mac models and see if your model / emc is listed there,



2) Open the computer to have access to the logic board and locate the debug port / SPI chip,




3) Ensure proper connection, the red led is light on SPI adaptor when connected to the mac board and the board is powered either by battery or charger.

-The red light on SPI Adaptor should light on when the logic board is powered by internal battery or external connector even if it not connected to the HDBOX.



4) Connect the SPI adaptor to the extension port of the HDBOX, and HDBOX to a computer running our HDBOX Manager software



5) On HDBOX Manager Software select iMac & MacBook tab and “Start Mac App” if the App is not running already



6) Click Detect SPI, this will detect the SPI chip present on the Mac logic board and will report the chip model and size



7) Click Read SPI to read the Image from the chip, and after read is done, Save to file to have a backup of it,



8) If you want to remove just the iCloud lock press “clear iCloud Lock” -or- to remove iCloud account from that computer press “Remove iCloud Account”. This changes will be done on the image you read from chip and saved to chip just yet,



9) After all desired changes are done, we update the SPI chip by either performing a full Spi write (chip will be erased entirely and rewrote entirely) or the a smart update by using Write SPI Sync ( Chip will be read again and only parts that were changed will be written to the chip )



10) After chip was updated and iCloud removed, is time to remove our adaptors from the board and put the computer back together



11) Now boot the mac and it should boot with no problem and greet you with user login screen now

Troubleshooting:
1# If your mac model is not on our list, or have different debug port:
Look on the board for a chip that looks like this, or an empty connector that looks like one of this two.




If is the chip, you have to use the SOIC 8 clam provided and place it with the red wire over the pin no1 of the chip.

If is the small debug port, use Adaptor no1, the red color one, and if upon insertion the red light on HDBOX SPI adaptor does not light when the logic board have power, then rotate the adaoptor 180degree

If is the big debug port, first use the adaptor 2, the blue color one, and if the red led does not light up rotate it 180 degree. If the red light still not light, then try use adaptor no3, the yellow color one in both positions.




2# Red light pass, but Detect SPI chip returns either “00 FF FF FF (Not Connected)” or “00 00 00 00 (Not Connected)”
3# Detect SPI returns good id, but read spi chip returns empty image (0xFF)
This means that mac computer still retain ownership of the SPI chip and different power states have to be tried until access to the chip is granted to our interface.


Different power modes can be tried by having battery connected or removed, charger plugged or not, computer on or not, different macs will work in different modes so you have to try the one that work for your mac.

4# Read was ok, but I have issues at writing to the chip
This means that while our interface was able to access the SPI chip in read only mode, the Write Protect line is protected by the mac. To fix this issue, please try different power state until mac release full control of the SPI chip.

– Other Issues –
Send us an email to [email protected] with some pictures of the board, the computer model and EMC number, and eventually the backup of the image you read from chip.
