"Software installation failed" error when booting up I got stuck at Huawei Logo and it won't start, then I followed this instruction 


  Download the same build you had before getting stucked or newer one, Extract it and transfer "dload" folder to the root of FAT32 MicroSD, Put the SD in the phone, Hold Vol+ and Vol- with Power button to boot into Upgrading mode


Then when the installation shows up it automatically says "Software Installation Failed". How to fix this problem? I found that some say that it must upgrade a transfer package provided by R&amp;D, and I don't know how to update it. I'm stuck in Huawei logo.
This procedure should work:


copy the dload folder(should contain update.app package provided by Huawei R&amp;D) in MicroSD card (root folder) and insert the MicroSD card in your phone.
Turn off the phone by removing battery or pressing power button longer than 10 sec.
Boot the device in recovery mode by pressing power + volume up key.
once it is booted in recovery, select "upgrade using external storage" using volume up, down and power key
navigate to update.app package and press power button.


It will start the installation process and your phone should work after upgrade.
