What Is the MobileSea Service Tool?
MobileSea Service Tool is a feature-rich Windows utility designed for working with a wide range of mobile devices. Depending on the operation and device model, the tool can work in both offline and online modes.
For certain advanced operations that require server authorization, an active internet connection may be necessary so the software can communicate with its online services and obtain the files or authorization data required to complete the process. MobileSea Service Tool was developed by Gautam Kumar, who has been associated with various mobile servicing and software tools over the years.
The software is offered as a paid service rather than a completely free utility, meaning users generally need to purchase access before using its available features. The pricing can vary depending on the selected access period,
with different options available according to how many days the user wants to activate the tool. Overall, MobileSea Service Tool is intended for technicians and experienced users who need a versatile Windows-based platform for different mobile servicing tasks.

The new version also continues the development introduced in earlier releases, including Xiaomi bootloader functions, Apple diagnostics, Samsung Exynos FRP support, and broader Qualcomm device coverage.
MobileSea Service Tool v7.9.1 Apple Module
The Apple module receives some of the most notable changes in version 7.9.1. Support for A12 and A13 Boot Ramdisk operations has been added, giving the tool compatibility with a wider range of Apple hardware. The update also introduces Passcode Backup and Restore functionality, along with a Factory Reset option and a feature for reading the installed iOS version. These additions make the Apple module more versatile when working with supported devices.
Another important improvement is the fix for the mounting problem that could occur on A7 through A11 devices. Users who previously experienced mounting errors on compatible older Apple hardware may find the process more stable after updating to the latest version. The developers have also expanded the Apple workflow while maintaining compatibility with the supported device generations.
Supported Apple Devices
MobileSea Service Tool v7.9.1 supports a range of Apple devices using the newly introduced Apple features. Supported models include the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone SE 2nd Generation, iPhone XS, iPhone XS Max, and iPhone XR. The supported iPad lineup includes the iPad Air 3rd Generation, iPad mini 5th Generation, iPad 8th Generation, and iPad 9th Generation.
Because Apple functionality can depend on the specific hardware generation and software environment, users should verify that their device is listed as supported before starting an operation. Compatibility may also depend on the required ramdisk and the particular function being used inside the tool.
Apple Ramdisk Requirement
The latest Apple features require the appropriate ramdisk files. According to the release information, the required ramdisk files should be obtained from the official MobileSea source rather than from random third-party websites. After downloading the correct file, it needs to be placed inside the designated MobileSea Tool data directory.
The required folder location is C:\MobileSeaTool\Data\DataFiles\Apple\boot. Keeping the ramdisk files in the correct directory allows the software to locate them during supported Apple operations. Users should also make sure that the ramdisk version matches the device and operation they intend to perform.
Qualcomm Module Updates
The Qualcomm module has also been expanded with additional Samsung device support. Version 7.9.1 adds the Samsung Galaxy A23 with model number SM-A235N and BIT-C support. The Samsung Galaxy S24 Ultra SM-S928N is now supported with BIT-6, while the Galaxy S24 Ultra 5G SC-52E receives BIT-1 compatibility.

Additional support has been introduced for the Galaxy S22 Ultra 5G SM-S908N with BIT-9, Galaxy S23 5G SM-S911N with BIT-8, and Galaxy S23 Plus SM-S916N with BIT-6.

Changes Introduced in MobileSea Service Tool v7.9.0
Before the newest 7.9.1 release, version 7.9.0 introduced several major changes. One of the main additions was Xiaomi bootloader functionality, including an experimental LK Patch method and a temporary bootloader unlock feature. The release expanded compatibility with selected Android 16 devices and offered limited support for certain Android 15 devices.
The Xiaomi section also gained support for many newer Xiaomi, Redmi, and POCO smartphones. This made the tool more useful for technicians working with recent Qualcomm-based hardware and Xiaomi devices. The update also included improvements to Fastboot firmware flashing, helping address problems that users could encounter during firmware-related operations.
Apple Improvements in Version 7.9.0
The previous 7.9.0 release added erase functionality for Apple A12 and A13 devices. It also introduced Boot Diagnostics through Boot Diag Mode. The release information notes that this diagnostic functionality requires compatible usbliter8 RP2350 hardware.
These additions expanded the Apple service capabilities of the software and prepared the platform for further improvements that arrived in version 7.9.1. The newer release builds on this foundation by adding additional Apple operations and improving compatibility with supported hardware.
Samsung Exynos FRP Support
MobileSea Service Tool v7.9.0 also introduced Exynos FRP support through Download Mode. The feature was reported to support devices with security patches up to May 4, 2026. This was a significant addition to the Samsung module and increased the range of Samsung service operations available through the application.
Since Samsung security versions can change frequently, compatibility should always be checked against the exact device model, chipset, binary or BIT version, and security patch installed on the phone. A feature available for one firmware generation may not necessarily work on another version.
Xiaomi Device Support
The Qualcomm module received a substantial expansion for Xiaomi devices. Xiaomi Bootloader Unlock support through SELINUX was added for selected models, while Fastboot firmware flashing received fixes. The update also introduced support for multiple newer Xiaomi, Redmi, and POCO products.
Among the newly supported Xiaomi devices were models from the Xiaomi 15 family and Xiaomi 13 family. Support was also added for the MIX Fold 3 and MIX Flip 2, together with the Pad 8 Pro and Pad 6S Pro. Additional Redmi compatibility includes the Redmi K90, K80 Pro, K70, and K60 Pro, while the POCO lineup gained support for the POCO F8 Pro and POCO F6 Pro.
New Samsung BIT Support
Version 7.9.0 expanded Samsung compatibility by introducing additional BIT support for a wide range of Galaxy devices. The supported models included the Galaxy A05s, Galaxy A23, Galaxy A23 5G, Galaxy F14 4G, Galaxy Z Flip5, Galaxy Z Fold5, Galaxy Z Fold6, Galaxy S21 FE, Galaxy S21, Galaxy S22 Ultra, Galaxy S23 Ultra, Galaxy S24, Galaxy S24 Ultra, and Galaxy Tab Active4 Pro.
The BIT or binary version is particularly important when working with Samsung firmware because the software and firmware combination must be compatible with the device's current bootloader level. Users should therefore verify the exact model and BIT value before attempting any service operation.
MobileSea Service Tool v7.8.7
MobileSea Service Tool v7.8.7 was released on December 16, 2025 and introduced another large batch of Qualcomm device support. The update focused heavily on OnePlus, Oppo, Realme, and Samsung models while also bringing general bug fixes and stability improvements.
The OnePlus additions included the OnePlus 12 with PJD110, CPH2573, CPH2581, and CPH2583 variants. The OnePlus 13 series, OnePlus 13R, OnePlus 13S, OnePlus 13T, OnePlus 9 Pro, OnePlus 9RT 5G, OnePlus Ace 3 Pro, Ace 3V, Ace 5, Ace 5 Pro, Ace 6, Nord 4, Nord CE 4, Pad 2, Pad 3, and Pad Pro were also included in the expanded compatibility list.
Oppo Support in Version 7.8.7
The Oppo section of the 7.8.7 release added numerous devices and regional variants. Supported additions included the Oppo A1 5G, A1 Pro, A5i Pro, A6 GT, A98, F21 Pro 5G, F23, F31 Pro+, Find N5, Find X2 Lite, Find X2 Neo, Find X7 Ultra, Find X8 Ultra, K10x, K11x, K12, K12 Plus, and Pad Air.
Different model numbers were listed for several of these devices, showing that compatibility was extended across multiple regional versions. Users should always compare the complete model number of their handset with the supported list rather than relying only on the commercial device name.
Realme Device Compatibility
Realme support was also expanded in version 7.8.7. The update included the Realme GT Neo 5 SE RMX3700, GT Neo 6 SE RMX3850, GT5 240W RMX3823, GT5 Pro RMX3888, and GT8 RMX6699. These additions increased the Qualcomm module's coverage of newer Realme hardware.
The exact model identifier remains important because the same commercial device family can have different hardware or regional variants. Before using any service function, users should confirm that the model shown by the phone corresponds to the version supported by the installed MobileSea release.
Samsung Support in Version 7.8.7
The Samsung portion of version 7.8.7 included a broad collection of Galaxy smartphones and tablets. The Galaxy A02s was supported for SM-A025U BIT-6 and SM-S124DL BIT-C variants. The Galaxy A05s received support for several variants, including SM-A057F, SM-A057F/DS, SM-A057G/DSN, and SM-A057M with their respective BIT levels.

The update also added Galaxy A23 5G variants such as SM-A2360, SM-A236M, SM-A236U, SM-S236DL, and SM-S237VL. Other additions included the Galaxy M23, Galaxy S20 FE 5G, Galaxy S21 FE 5G, Galaxy S21+ 5G, Galaxy S21 Ultra 5G, Galaxy Tab A 8.0 2018, Galaxy Tab A7 10.4 2020, Galaxy Tab A9+, and Galaxy Tab S5e.
OnePlus, Oppo, Realme and Samsung Expansion
The combination of OnePlus, Oppo, Realme, and Samsung additions made version 7.8.7 a major Qualcomm compatibility update. Rather than focusing on only one manufacturer, the release broadened the range of supported Qualcomm-based devices across several popular Android brands.
For technicians and service users, the most important point is that support is model-specific. Having a phone from a supported brand does not automatically mean every device from that brand is compatible. The exact model number, chipset, software version, security patch, bootloader state, and other hardware conditions can affect whether a particular function is available.
Bug Fixes and Stability Improvements
Along with new features and device support, MobileSea Service Tool updates have continued to include general fixes. Version 7.9.0 specifically addressed Fastboot flashing problems and minor software bugs while improving overall stability. Version 7.9.1 continues the maintenance cycle by fixing the Apple mounting issue reported on A7 through A11 devices.
Keeping the application updated can therefore be useful when working with supported hardware because newer releases may contain compatibility changes that are not available in older builds. However, users should still maintain proper backups and verify device compatibility before performing any operation that can modify device software or data.

MobileSea Service Tool v7.9.1 Overview
Overall, MobileSea Service Tool v7.9.1 represents a focused update that expands Apple functionality and adds more Samsung Qualcomm compatibility while continuing improvements introduced in previous versions. The A12 and A13 Boot Ramdisk support, Passcode Backup and Restore, Factory Reset, iOS version reading, and Apple mounting fix are the major highlights of the newest release.
The Qualcomm module also benefits from additional Samsung BIT support covering several recent Galaxy models. When combined with the Xiaomi bootloader improvements, Apple diagnostics, Exynos FRP support, expanded Xiaomi compatibility, and the large OnePlus, Oppo, Realme, and Samsung device additions from earlier releases, the MobileSea platform now covers a broad range of modern mobile hardware.
Users should obtain the software and required Apple ramdisk files only from trusted or official sources and carefully check the supported model, firmware, security patch, and BIT information before using any service feature. Because device compatibility can change between firmware releases, the safest approach is to match the exact device information with the release notes before proceeding.
