Device Connection Modes — How to Enter Them

Most phone servicing tools require the phone to be in a specific low-level mode before connecting. Here is how to enter each mode:

Mode	Chipset	How to Enter	Windows Device Manager shows
BROM / PreLoader	MediaTek (MTK)	Power OFF phone → press and hold Vol+ OR Vol- (varies by model) → plug in USB cable. Alternatively use test point to short BROM pads	"MediaTek PreLoader USB VCOM" or "MT65xx" or "MediaTek USB Port"
EDL (Emergency Download)	Qualcomm (QC)	Use ADB: `adb reboot edl` OR short the EDL test point on the PCB while plugging USB. Some devices: hold Vol Up + Vol Down while connecting USB	"Qualcomm HS-USB QDLoader 9008" or "QHSUSB__BULK"
Download Mode	Samsung	Power OFF → hold Vol Down → connect USB cable (newer Samsung). Older models: hold Vol Down + Home + Power simultaneously	COM port appears in Odin (yellow box)
SPD Download	Unisoc/Spreadtrum	Power OFF → hold Vol Down → connect USB cable	"SPD Interface" or "SPRD U2S Diag" in Device Manager
Fastboot Mode	All brands	Power OFF → hold Vol Down while connecting USB OR via ADB: `adb reboot bootloader`	"Android Bootloader Interface" or "Android" in Fastboot
ADB Mode	All brands	Enable USB Debugging in Developer Options (Settings → About → tap Build Number 7× → Developer Options → USB Debugging). Connect USB → authorize PC on phone	"ADB Interface" or device listed under Android devices

Troubleshooting EVO Tool Unlock

Problem	Solution
Carrier unlock fails	Ensure the phone is in the correct mode (ADB for code-based, BROM/EDL for direct patch). Verify IMEI reading matches the phone's actual IMEI (*#06#)
FRP bypass — device reboots to lock screen instead of Setup Wizard	This may require a factory reset first. Or try a different FRP method from EVO Tool's method selection (ADB, MTP, EDL vary in behavior per model)
NCK code received but rejected by phone	Verify the code was generated for the exact IMEI. If the phone shows "incorrect entries remaining: X" — stop immediately and contact code-gsm.com to avoid counter exhaustion
Drivers not installing on Windows 11	In Windows 11, disable Driver Signature Enforcement: hold Shift → Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → press F7

Frequently Asked Questions

Q: Does EVO Tool support iPhone unlock?
A: EVO Tool is primarily an Android tool. iPhone carrier unlock is a different service (IMEI-based Apple database unlock) available separately at code-gsm.com.

Q: How many credits does each operation consume?
A: Credit cost varies by operation type and device model. The credit cost is displayed in the tool before you confirm the operation — you can check without executing.

Q: Can EVO Tool unlock a Samsung that has run out of unlock code attempts?
A: Yes — EVO Tool can use direct USB MSL patching (download mode) which bypasses the code entry counter entirely. The code-based unlock and direct unlock are separate methods.
