Hi,
after gaining root access on this device (tp-link ax20 AX1800 v1) I tried to make some changes permanent by using nvrammanager, unfortunately it throws an error while trying to read the "file-system" partition.
# nvrammanager --read=/tmp/files/test --partition=file-system
[NM_Error](nvrammanager_readPtnFromNvram) 00538: partition is empty
same error for "os-image" but working for others, have not test all but "user-config" works.
here is the output from "-s", clearly the partitions are not empty, maybe some protection is in place ?
do we need to take a deeper look at nvrammanager ?
# nvrammanager -s
