It's not suggested to jump from very old firmware to the latest. You may try upgrade by following sequence.
V2.21 => V3.00 => V3.30
Firmware can be downloaded from the official ftp site and login with anonymous account.

Maybe you can try to use firmware recovery to upgrade USG 50 to the latest version.Check Appendix 3. Firmware Recovery in the release note.ftp://ftp.zyxel.com/ZyWALL_USG_50/firmware/ZyWALL USG 50_3.30(BDS.9)C0.zip0

Dear customer,
Is it maybe because you tried to flash it with the zip file instead of the bin file.
(so unzip the (firmware).zip file)
and use the .BIN file instead.
kind regards

I believe you have received the answers, but compilation:
1, Backup your configuration, backup your configuration, backup your configuration.
2, Like Mark said: Make sure you unzip and upload the .bin file, not the .zip.
3, Like Blabababa said do not jump from such an old firmware directly to the latest one. His/Her suggestion on jumps is good: V2.21 => V3.00 => V3.30. If there are still issues try even smaller increments.
4, Do not do the upgrade by doing a firmware recovery as explained in appendix 3 in the release notes.
