While attempting to update a old 8800, I got error 507 "nuked it "

I am not able to upload any OS (ofcourse deleted vendor.xml)
I tried 3 versions from old one to latest.
8800C_PBr4.2.1_rel164_PL2.3.0.80_A4.2.1.101_O2_UK. exe
8800M_PBr4.5.0_rel81_PL2.7.0.68_A4.5.0.55_O2_UK.ex e
8800M_PBr4.5.0_rel312_PL2.7.0.109_A4.5.0.187_O2_UK .exe
None of the above helps me to upload a OS.
Is there any other tools or way, I can use to upload the OS
