    Hey,

    First of all, thank you very much for this nice article. Unfortunately I forgot Step 3 and did not put the operating system zip file on my phone prior to step 10 and now Im stuck. Is there any way to still get the file onto my system in order to proceed? Im am very desperate now, because I cannot use my phone. Can you please help me?

    Hi,

    I am stuck at point 8.

    Zip file is found, but installation process lasts less than 2 secs. Reviewing the text that appears on the bottom half of the mobile, there are some “unable to mount” and “unable to unmount” directories.

    I have found an option called “format system”, but looks quite terrifying…

    ¿Any ideas?

    Thanks in advance.
