Now, you're going to need this modified fastboot. You're also going to need this private key used to sign a lot of Unisoc devices. You're going to need these scripts. Also, you're going to use a Linux based PC so make sure you get that in place. Now, once you have these in place, launch terminal by right-clicking and you select Open in Terminal.
Now, you're going to (or might) run into a couple of issues when using Linux as I did so this is just how to go about (fixing) them. You're going to first elevate your permission level then you're going to run this command to enable you have the permission you need to run fastboot. Now you're going to cd back to the fastboot folder so you just copy the path up here, paste then you tap Enter. Now you're back in fastboot directory. You boot the device into fastboot mode, you can use any method you wish. I boot from recovery mode usually and then I have detection. Next you get the identifier token by running this command.
Now, you select the identifier token then you paste it into this next command. Make sure there's just a space between the token and the private key in the command. Now you select.. sorry, select this, paste and and run (tap Enter). This is going to generate a signature.bin file. Yes, this is the file. Now, you're going to unlock bootloader proper. You paste. At this point, usually, your device is going to request for you to hold a button. I'm yet to run the command though but usually, your device would ask you to authenticate or verify Bootloader unlock either by pressing a button or thereabout. I'm going to run this right now and on my device, I have a confirmation prompt. In my case, I need to just tap volume down. Its going to vary with yours.
Once that is done, you're going to have the phone going into Erase Mode. Its going to erase your data so ensure you had backed up your important stuff before unlocking the bootloader and wait till that is done. Once the bootloader is done (with) unlocking, you're going to have a success message like I have here. At this point, you can either disconnect and boot up the device by holding the power button or you could run fastboot reboot. So that's how to unlock the bootloader of a Unisoc (SPD) Android 9 (Pie) device using its unlock token.
(28-02-2020, 06:25 AM)clay#027 can I just replace that modified fastboot in sdk platform tool folder that already installed in c drive sir ?
I'm talking about windows 10 without Ubuntu setup on it

(06-05-2020, 06:37 PM)simone Hi, im using this guide to root teclast p80x, in my win 10 i create a usb live with ubuntu inside, it works. Now when i try t o follow the command in fastboot ( cd path) it gave an error, bash no such a file or directory.... Since im not familiar with ubuntu and since it is live version maybe do i need to install some command or libs? i repeat that im not familiar with it so plaese if you can point me some hint would be great.
