Android Multi Tool Error Codes 2, 22, 31, 995: How to Fix

Android Multi Tool error codes 2, 22, 31 and 995: how to fix them

Most numbered Android Multi Tool errors are a USB link failure with the phone, not an account problem. You can tell by the text: Unable to open COM port, error 2, 22, 31, 995. Separately there are network ones — Error sending data and 12007 — where the issue is server access. Below is what each code means and where to start.

Code table

Code	What it means	What to check
Unable to open COM port (error 2)	port busy or did not open	close other service tools, reconnect the phone, change the port
error 22	the port link dropped	a direct USB 2.0 port on the back, a different cable
error 31	the driver is not responding	reinstall the mode driver (VCOM/Qualcomm), disable USB auto-sleep
error 995	the operation was killed by the system	disable USB auto-sleep and power saving, do not touch the cable mid-run
Error sending data / 12007	no server connection	network, DNS, VPN — see the Error 12007 article

Step 1. Drivers and mode

Codes 2, 22 and 31 are almost always about the driver and the connection mode. Install the driver for the phone’s chip: for MediaTek the VCOM driver (MediaTek VCOM on Windows 11), for Qualcomm the QDLoader 9008 (Qualcomm 9008 driver). How to tell the chip and mode is in the identify-chipset guide.

Step 2. Cable and port

Use a direct USB 2.0 port on the back of the desktop, not USB 3.0 and not a hub.
The cable must carry data, not just charge.
In Device Manager, uncheck the USB controller option that allows turning it off to save power.

Step 3. If the error is network-side

Error sending data and 12007 are not about the phone but the network: the tool could not reach the server. Checks with nslookup and netsh, changing DNS and using a VPN are covered in the Error 12007 article.

Step 4. Credits and account

If the link is fine but the operation still will not run, check the credit balance: some server-side AMT operations spend credits. How credits work and how to top up is in the AMT credits article.
