How to Unlock Bootloader on any Unisoc/Spreadtrum Device

The process will wipe off all the data from your device and might nullify its warranty as well. So take a backup beforehand and proceed ahead at your own risk. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing these steps.

To begin with, you need a Linux PC or a Linux Live USB on Windows.
Next up, go to Settings > About Phone > tap on Build Number 7 times,
Then go to Settings > System > Developer Options and enable USB Debugging
Now connect your device to your PC via a USB cable.
Then download this modified Fastboot binary package and extract it onto your PC.
Now right-click inside that folder and select Open in Terminal.
Then execute the below command to boot your device to Fastboot Mode
```
./adb reboot bootloader
```
Now execute the below command to get hold of the Identifier Token
```
./fastboot oem get_identifier_token
```
The output should be something along the following lines, with the token number in the second line. Copy it somewhere.
```
Identifier token:
XXXXXXXXXXXXXXXXXXXXXXXX
OKAY [ 0.027s]
finished. total time: 0.027s
```
Now execute the below command, replacing X with the copied Identifier token
```
./signidentifier_unlockbootloader.sh X rsa4096_vbmeta.pem signature.bin
```

You will now get an output along the following line:

Identifier sign script, ver 0.10
1+0 records in
1+0 records out
60 bytes copied, 0.000376481 s, 207 kB/s
Identifier sign successfully

Likewise, you will get a signature.bin file in the Fastboot folder as well.
So execute the below command to flash that signature.bin file:
fastboot flashing unlock_bootloader signature.bin
You will now get a prompt on your device asking you to confirm the unlocking process, press the Volume key to do so.
Your device will undergo a reset and the bootloader will then be unlocked.
Once done, use the below command to boot the device to the OS:
```
./fastboot reboot
```

That’s it. These were the steps to unlock the bootloader on any Unisoc/Spreadtrum device. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you with a solution at the earliest.
