ZTE680 Hardware V4.0 (V2?) Hack
Domingo, Agosto 20th, 2017I just got recently installed my first FTTH router (pepephone, but same model is used in masmovil and jazztel) and as any network engineer I wanted to have full access to the router. Looking over the vast internet I found a blogpost that used a USB with a symlink to smb.conf so it can be edited to add exec parameters to execute an downloaded busybox to open an alternative telnetd but the article had a big problem that make it imposible to work on my router: the F680 of the article has an ARM architecture. My router has MIPS instead. This is important to know beforehand if using external-downloaded busybox binaries. In the end I skipped the busybox hack to directly allow admin telnet connection instead the buggy limited one. This is how I did it, I will assume that router has IP address 192.168.1.1.
