routerboard 532 netinstall problem

Hi all,

i am trying to reinstall my RB. i have tried various packages versions (2.9.11, 2.9.22, 2.9.23, 2.9.24)

Waiting for installation server…
Found server at 00:0C:6E:3D:54:77

Formatting disk…

installing routeros-rb500-2.9.23 [ ]

At this point i get the error message 100004 Sendto() failed;

The netinstall hangs up and the rb writes in a while:

Waiting for installation server…
Found server at 00:0C:6E:3D:54:77

Formatting disk…

ERROR: installation of routeros-rb500-2.9.24 failed: broken package
WARNING: package system-2.9.24 onuninstall script failed

FATAL ERROR: bad network connection
Press ENTER to reboot

The packages are ok. i have done all memory test from bios. now i have a bios version 1.13(latest)

Is there any possibility to upload the package to RB over serial cable?

any suggestion?

thnx

formatting your nand should be possible in the new biso version - that should help
