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 MobileSea Tool

Problem	Solution
Phone not detected at all	Check that USB Debugging is enabled (ADB operations). For BROM/EDL: install MTK VCOM or Qualcomm 9008 drivers. Try a different USB cable and port
FRP bypass completes but prompts for account on reboot	After bypass, go to Settings → Backup & Reset → Factory Data Reset. Then set up device without adding any Google account
Mi Account removal fails	Ensure device is in EDL (QC) or BROM (MTK) mode for Mi Account removal — ADB-based removal may not work on newer MIUI versions
Flash fails midway	Check USB cable quality. Ensure PC driver is correct for the chipset. Disable antivirus. Run MobileSea as Administrator
Credited consumed without result	Contact code-gsm.com support with the log file from MobileSea Tool's log directory

Frequently Asked Questions

A: Yes — one-click Magisk root is supported for selected models. Check the supported list within the tool.

Q: Does MobileSea need an active internet connection?
