Solution for "'DSA verify failed"-error found #75

Closed gramc1106 closed 1 year ago

gramc1106 commented 1 year ago 
          I ask you for help: I did everything according to rajkosto´s instruction to flash my ZTE H288A which I got from an Austrian ISP. While trying to upload the "t16mod_fwupgrsignaes.bin" via http://192.168.1.254 I get the error message  "DSA verify failed !" (although uploading/sending "83FBC5C8_dsaverifyfunc_ret0.bin"-file with "xmdm 83FBC5C8 D4" > XMODEM was done).

The message in my "Tera Term"-terminal is the following: ...

bldr> xmdm 83FBC5C8 D4 CCCreceived error bldr> START TO RECEIVE the FILE

The problem was that I didn´t took the right firmware. With the firmware suggested by [rajkosto] commented [on Nov 2, 2022] (.bin file inside this archive https://files.sshnuke.net/t16mod_fwupgrsignaes.7z) it didn´t work (in contrast to all other instructions by him, which worked like a charm in regard to this issue). The firmware which worked for me was [zxhnh288a_hv11_fv110_gr51t16_firmware.bin]Nova zxhnh288a_hv11_fv110_gr51t16_firmware.bin, posted by datio on Oct 20, 2022](https://github.com/mkst/zte-config-utility/issues/43#issuecomment-1286159848).
