altdb is an alternative ADB server from Dr-TSNG that allows a computer to connect to an Android device using a standard ADB client. It was introduced as a side-channel debugging option for KernelSU users.
An Alternative ADB Connection
The developer describes altdb as a separate ADB server that ordinary desktop ADB tools can connect to.
Side-Channel Server
altdb offers an ADB server separate from the usual device debugging path. It is intended for connections from a computer.
Standard ADB Client
The computer side uses an ordinary ADB client; the developer does not describe a dedicated desktop application as a requirement.
Source and Availability
The original Dr-TSNG/altdb repository is currently unavailable following the developer's GitHub account suspension. A current release, installation procedure, supported Android versions, connection ports, and security settings cannot be verified from the first-party repository. This page therefore does not provide an unverified package or setup instructions.
Debugging Access Requires Care
An ADB connection can expose sensitive device controls. Do not install repackaged altdb archives from an unverified source or expose a debugging server to an untrusted network while the official project and its security documentation are unavailable.
