The phones died most of the time trying to root and downgrade. Just use Flashtool v0.9.13 and download the latest FW for your model from HERE, wipe Data, Appslog and Cache and all will be fine, or wait for OTA, but there is no difference.

The point is if he do not have Updates or he do not have the latest update and want to update then he have to use Flashtool, anyway flash from PC Companion or with Flashtool there is no difference, they do the same thing.

It says he got global version so he should get latest updates through SUS or pc companion. From what I can see hes phone is not carrier locked with bloatware. Flashtool is best for every locked and unlocked versions. It just sounded like he is afraid of using it, and that was bases for suggestion to keep it safe...;)

    Just use SUS or PC Companion. It is safe way to get updates for your Z1.
