Requisites:   Dead phone USB Cable  You tried tons of tutorials to unbrick the phone and didn't work This image Willingness to even use Linux to fix it (it's not hard) Steps: Create a bootable USB using the image downloaded. Make sure your computer allows booting from USB. Boot the computer from the bootable USB. When booting, a list of options will be shown. Pick the first one: Boot Live system. Once the system is loaded, go to the right-upper corner to connect to Wi-Fi.

Unzip the tool downloaded. Download the fastboot version of the stock ROM . Unzip the ROM, to have the folder and files. Click on 'MTK' icon that is in the desktop. In the command line opene

Changing Size of VirtualBox Disc

Since I decided to use Linux, because I like it a lot, I knew that I'll need Windows anyway due to the fact that everyone (at most) uses it and considering also that my posts would have to be focused in this operating system (my readers use it).

To overcome this situation I decided to install a virtual machine on my Linux (Debian specifically) to avoid rebooting anytime I need to do something in Windows, to accomplish this purpose I installed VirtualBox and installed in it Windows 7.

However, In some point there was need to get more disk space but I couldn't get it because when you define a virtual machine you specify a determined disk size. But, it can be done the following to increase the disk size using the tools provided by VirtualBox.

First, increase the disk size by using a VirtualBox command created for this task. Remember that the virtual machine has to be turned off to be able to modify the virtual disk, once you are sure about this, go to the configuration of the machine.
 
Enter to virtual machine configuration

Then, go to "Storage" section and pick your virtual disk, this is just to get the physical path of it in your computer, copy it from "Location" label.

Go to storage and find the disk path

With this path copied go to a command line and execute "vboxmanage modifyhd <your_disk_path> --resize <new_size_in_megabyter>", it's very similar in Windows so you won't have any problem, in this example I'm increasing the size to 26 GB.

Use the command line to modify the size

Now you have your virtual disk with the desired size, but as a physical disk it's necessary to assign the new space to the operating system, to do this boot the virtual machine (in my case Windows) and go to "Start", right click over "Computer" and click on "Manage".

Enter to PC administration

In the new window go to "Disk Management" and you will see not assigned space (consequence of the size increment), just right click over the partition next to this free space and select "Extend Volume...".

Increase volume of the disk

Finally, select the amount of bytes you will need in the new partition and that's all, more space for your virtual machine.
