UnlockTool download & install guide
A clean first install: antivirus exclusions, drivers, admin rights, and the fixes for first-launch errors.

Most support tickets come from two skipped steps: the antivirus exclusion and the drivers. Do both first.
Only use the official setup
Repacked or "cracked" builds cannot authenticate with the license server, so they either fail at login or (worse) halfway through a flash. Get it from the download page and verify the MD5.
Add an antivirus exclusion before extracting
Low-level USB and driver access looks suspicious to heuristic scanners, so false positives are normal. Exclude the folder you will install into before extracting, or loader files get quarantined silently.
Install
- Extract to a short path like
C:\UnlockTool. - Right-click the program and choose Run as administrator. Do it every time.
- Allow it through Windows Firewall when asked.
Install drivers before plugging in a phone
- USB / ADB drivers for general detection
- VCOM / preloader drivers for MediaTek
- Qualcomm 9008 (EDL) drivers
Use a rear USB 2.0 port on the motherboard (no hubs, no front panel) and a cable you know carries data.
Quick fixes
- Files vanish after extracting? That's your antivirus. Add the exclusion and extract again.
- "Server connection failed"? Check your firewall or proxy and allow the tool explicitly.
- Login rejected? It's one of three things: no active license, the wrong account, or an unofficial build.
- Device not detected? Check the drivers first, then the cable, then the port.
- Fails part-way? Update to the newest build and try again.
