No! wait.. don't throw it away... and don't use Rodinal! Neofin Blue should be most suitable, as it raises the box iso of the given film by half. Also D76 1:1 may be a help. I pushed tx400@4000 with D76 1:1 and obtained quite printable frames, but mind that Adox CHS 100 is a traditional single layer film and can be reacting to pushing process way different than Kodak Tx .
