Root: Build Custom Firmware with Telnet
Telnet root shell can be enabled by creating a custom firmware, naming it 'ezviz.dav', placing it on the SD card, and rebooting:
1. Download Hikvision packer/unpacker (to Linux PC):
https://ipcamtalk.com/threads/mcr-hikvision-packer-unpacker-for-5-3-x-and-newer-firmware.15710/
2. Download original firmware:
3. ./hikpack -t r0 -x digicap.dav -o newfw
4. cd newfw
5. unsquahsfs app.img
6. cd squashfs-root
7. nano initrun.sh and add '/bin/busybox telnetd &' to the end to enable telnet (or make any changes you want)
8. cd ..
9. mksquashfs squashfs-root/ app.img -comp xz -b 256K -noappend -force-uid 4145 -force-gid 4148
10. rm -rf squashfs-root
11. ./hikpack -t r0 -p ezviz.dav -o newfw
12. Copy ezviz.dav to SD card
13. Insert SD card to camera
14. Reboot camera
15. Log in to telnet with root/EHLGVG
- NOTE: This works because the current version of the firmware checks for the existence of 'ezviz.dav' when booting up. Also, the root password is hard-coded to all devices.
