A: Usually yes, unless the repack reformatted the hard drive. Disconnect the HDD before resetting, then reconnect afterwards.
A: No. Repacks are chipset-specific. A Hi3516 repack will not work on a Hi3531 DVR. Always verify your chipset first.
Find a repack tailored to your Hi Sharp chipset (typically Hi3515, Hi3516, Hi3520, or Hi3531). The filename often includes _reset_password or _nopass .
Set your PC’s IP to 192.168.1.100 (since many Hi Sharp DVRs default to 192.168.1.108 ).
Select your DVR. Click “Reset Password” or “Clear User Data”. The repack sends a specially crafted packet that forces the DVR to factory reset only the user credentials.
But what exactly does "repack" mean in this context? Is it safe? And how can you reset your forgotten password without losing your critical footage or bricking your device?
| Risk | Likelihood | Consequence | |------|------------|--------------| | | Medium-High | Keyloggers, ransomware on your PC | | Bricked DVR | Medium | Device becomes unusable (no video output) | | Erased footage | High | Entire HDD partition table reset | | Network backdoor | Low-Medium | Repack leaves hidden admin account for attackers |
