warning - the fw used for factory default reset in RUT955 is faulty!
Founf that with my new router RUT955 T033B0, sn 1102315792. it has ample of space for rootfs, but anything stored in that space is not permanent (gets wiped out with reboot or power break. upgrade to a working fw only succeeds via bin file upload, not via server download. see the details below.
df -h output of the new router:
