Fail access to back office while upgrading to 1.6.0.6

[luthanhphu]

I was using 1-Click Upgrade utility to upgrade my shop from 1.5.2 to 1.6.0.6, everything was fine except for a fatal problem causing by me.

 

I forgot to change permission to 777 on my host, so after checking and download the newest version the utility can't automatically upload to autoupgrade folder and asked me to do manually it by using FTP. At this step, I clicked "refresh" to reload the back-office page, unfortunately both of front and back office comes to maintenance mode and I can't do anything.

 

Then, I tried to follow by extracting the zip file to latest folder in admin. 

 

In this step I don't know what to do next to continuous my upgrade process?

 

Please help.

 

Thanks.
