@amg you are right on Zgemma H7 SATtek elegance BLUE base image , there is a little issue on base skin wich make hang the device , but it's only a little error that you can solve installing the ipk given inside the package you have downloaded.
This issue is due to the fact that I have not any H7 so I have to work "in a blind mode" on this device so I can not test on it the software in order to find mistakes and issues on it.
So when the H7 hang on booting you must freeze it by telnet command:
Then put the ipk package in /tmp and install it following the instructions you can read at the end of first post on this following topic :

If you want an image backup complete and very good all over its parts you can install this one:
[BCKP] ZGEMMA H7 openATV6.2 [isetE2+ExteP3+XC6.1+Ytube+WRadio+SATload+NSpeed] GIO965 optimizations
Talking about Zgemma H5 its odd what I read , cause the Zgemma H5 was tested so I am 100% sure that the software ( eache one we released as SAT.technology backup-image software ) is perfect in function and working very well !!
