Hi I recently got a nice Lenovo A806 phone from China but it has a custom version of Android which does not include google playstore or playstore services. I've been directed by my vendor to a blog which gives good instructions for rooting and reflashing the phone.

I'm a linux user and complete novice wrt rooting and flashing but can borrow a Windows computer to do the job. I've downloaded the recommended rar files but they are all password locked. The source sites for the files are Chinese so I can't find any help there. I've looked for rar cracking software and tried a couple but they don't seem to have worked on my download files.

Can anyone help please?
