unable to Update Routeros

Hello everyone. I just bought a router hap lite tc and I got two problems when I wanted to upgrade the Routeros to 07.
First of all i got not enough space error when I wanted to upgrade, I tried to search about this problem and I got that I must upgrade manually. Ive downloded serveral versions and each time after drag and drop and then reboot from system noting changes and again the os version still the same 6.47.9.

That device is a no-go for ROS7.
Not enough resources.

Best you can do is 6.49.7 stable or 6.48.6 Long Term

Netinstall the device with 6.48.6 and never update/upgrade again.
The SMIPS device has already reached the end of life with 6.47.x

Version 6.47.9 has a bug in it often not enough memory to install a new version of ROS. In this case there is a patch fix-space-6.47-smips which frees memory or use netinstall.
