DS-809SE applicable models and methods of use
DS-809SE supports the full range of motherboards with SAM interface Apple notebooks and various brands of BIOS chip data read and write
1. DS-809SE is suitable for
MacBook Pro 2010-2017 (A1286, A1278, A1425, A1502, A1398, A1706, A1707.A1708)
MacBook Air 2010-2017 (A1369, A1370, A1466, A1465)
MacBook 2015-2017 (A1534)
iMac 2010-2016 (A1200, A1225, A1224, A1312, A1311, A1418, A1419)
Mac Mini 2010 – 2016 (A1347)
Unlock other models (unlock firmware lock, PIN code lock, iCloud ID lock, modify motherboard serial number, add motherboard serial number, modify ME in BIOS data, read and write BIOS data) and other functions.
It can also be applied to read and write BIOS chip data and unlock BIOS passwords of various brands such as Dell, HP, Lenovo, Asus, Acer, Sony, Samsung and other models.

Second, DS-809SE is an upgraded version of DS-809S
Advantages of DS-809SE:
1. The method of use is simpler and the speed of reading data is faster.
2. Added four sets of stable voltages. The function of the four sets of voltages is to provide a stable power supply to the motherboard BIOS chip, making it easier for the device to read the information of the BIOS chip.
3. The input voltage display screen of the probe has been added to make it easier for users to see the input voltage of the probe to the BIOS
4. Added BIOS chip holder, more method to read the BIOS chip of IMAC machine and read and write BIOS chip data for computers of various brands
5. The SAM connector uses a four-layer mini motherboard, which is more convenient to connect to various motherboards
6. SAM cable adopts direct cable, which is more convenient for users to connect to the device
6. Support more BIOS chip models and more stable performance.
How to use four sets of voltages:
(Four sets of voltages 2V, 2.5V, 3V, 3.3V adjust different voltages in different years. If the voltage adjustment is high, it will not cause any damage to the motherboard, but will only affect the failure to read and write data. The four sets of voltages are output through probes To the power supply pin of the BIOS chip on the motherboard)
1. The 2V voltage is suitable for Macbooks from 2016 to 2017. If the reading error is reported, the voltage can be adjusted to 2.5V
2. The voltage of 2.5V is suitable for the Macbook Pro Air from 2015 to 2017, and the voltage can be adjusted to 3V if an error is reported.
3. The 3V voltage is suitable for Macbook Pro Air from 2010 to 2014.
4.3.3V voltage is suitable for 15-inch Macbook Pro from 2010-2014.
5. When using the BIOS cable clamp, there is no need to use a probe, just connect directly to the motherboard to read the BIOS data
How to use the probe: Connect the probe pen to the probe hole, and then point the probe pen to the power supply pin of the BIOS chip.
The unlocking method of the whole machine documentary motherboard:
1. Disassemble the bottom case of the Macbook and disconnect the battery from the motherboard
2. Install the device software on the Win system computer, connect the DS-809SE to the computer with a USB cable, and find the corresponding SAM socket on the other side and connect it to the Macbook motherboard.
3. Find the connection point on the motherboard that communicates with the power supply pin of the BIOS chip
4. Connect the probe pen, adjust the voltage, and point the probe to the connection point of the corresponding BIOS chip power supply pin
5. Read BIOS information
6. Remove the password in the BIOS data and unlock it

Three, DS-809SE software pin error setting

1. Open the software and click Setting

2. Click Programming setup options,

3. Then, uncheck Open the PINs contact test and Auto verification af, and click save to save

Fourth, DS 809SE decryption (unlock firmware lock, EFI lock, PIN code lock) method

1. Open WinHex software, then Ctrl+F

2. Enter the uppercase $SVS (if there are more than one SVS content from the bottom), select All for Search.

If you can’t find it, slide the mouse down first, and then select Down

3. After searching for the content of $SVS, go down 7 lines and choose the starting block, then go down to the FF line and choose the ending block. The content selected in light blue is the EFI password encrypted content.

Ctrl +L fill in FF, click OK

4. Finally click save

5. Finally, write the unlocked file back to the BIOS chip.

Operations after writing data

When powering on for the first time, keep holding down the Command (⌘), Option, P and R keys, and then press the power switch, the computer will restart automatically, and the screen will turn on and off after restarting three times and then release the four keys

Five, serial number modification

1. Open WinHex software

2. Then Ctrl+F, fill in lowercase ssn, click OK

3. After searching the content of ssn, directly input letters and numbers in the text field to change the serial number,

If there are multiple ssn in the search, you must change them together
