The installation with TWRP is completed without an error message, but the /e/OS system only starts up to the animated e-logo. Nothing else happens for minutes.
The /eOS-U system cannot be used, but the /e/OS-U installation leaves a /e/OS-U-Recovery, which means - the /e/OS-U overwrites the pre-installed TWRP recovery. This is not cool!
A second attempt to install /e/OS-U without e-Recovery in /e/OS-U.zip was also successfully completed by TWRP-Recovery, but the end result is the same: /e/OS-U does not start, gets stuck in the installed e-Logo.
