[Tutorial] How to unlock Unisoc (SPD) bootloader using Identifier Token
[Tutorial] How to unlock Unisoc (SPD) bootloader using Identifier Token
(08-05-2020, 10:34 PM)lotus118 Thanks for the guide! I have two questions:
1: do you know how the fastboot binary was modified? What does it do that the original doesn't?
2: I tried this procedure on my Alcatel 1C (2019, model 5003D) and it didn't work. The last step says "FAILED (remote: Unlock bootloader fail.)". I assume this may be because Alcatel uses a different key to sign than is provided in the link in this post. Do you know if this is the case and, if so, where I can find Alcatel keys?
Thanks!
(09-05-2020, 11:13 AM)X3nonDo you know what those commands are? Is the source code for the modifed fastboot available somewhere? I tried searching russian forums for the original post but my Russian isn't great and Google translate isn't much help.(08-05-2020, 10:34 PM)lotus118 Thanks for the guide! I have two questions:

1. its not modified per say, rather compiled with commands for unlocking / locking unisoc bootloader included
2. No. if your device uses a different keys then only your OEM can help you with that
(11-05-2020, 01:23 PM)lotus118 Do you know what those commands are?
fastboot oem get_identifier_token
fastboot flashing unlock_bootloader signature.bin
fastboot flashing lock_bootloader

(18-05-2020, 08:57 AM)AshLFC_01 I'm facing a problem when trying to run the 6th command. It gives out an error (bottom line of the screenshot) saying that the 90th line of signidentifier_unlockbootloader.sh has a problem, indicating that no file such as padding.bin exists. On another note, the modified fastboot which was provided had a signature.bin file already, which I believe is supposed to be generated after I run the command above.
If I remove the 90th line, the command works successfully, but it doesn't provide this:
"Identifier sign script, ver 0.10
1+0 records in
1+0 records out
50 bytes copied, 0.000257562 s, 194 kB/s"
...and the signature.bin file which is generated is only 512 bytes.
So, it's natural to see that the unlock bootloader command doesn't work as expected. What should I do?

Moving it to the desktop didn't work (first attachment), so instead I just changed the permission of the folder. I have successfully been able to unlock the bootloader thanks to this. I literally couldn't find any other solution to unlock it for my phone.
for the input/output error, it seems dd is unable to write a new file in that location i.e /media/ubuntu/*****/modified_fastboot
move the folder to a different location with write permission e.g your desktop and retry the command

cd /home/your_username/Desktop
in your case, your_username should be root
