- Custom Firmware Flashing: It enables users to flash official and custom firmware onto smartphones, which is useful for restoring phones that are bricked or locked.
- Factory Reset Protection (FRP) Removal: UFI Box can remove FRP locks, which is critical when servicing phones that have been factory reset but are still tied to a Google account.
- Unlocking Bootloaders: UFI Box also supports unlocking bootloaders, which is crucial for developers and advanced users who wish to root or modify their devices.
4. How Easy JTAG and UFI Box Are Used in Honor Devices
Honor phones often come with locked bootloaders, security protections like FRP, and sometimes even network locks or encrypted firmware. Tools like Easy JTAG and UFI Box can be invaluable for repairing or unlocking such devices.
Unlocking Bootloader:
- Unlocking the Bootloader is one of the most common uses for tools like Easy JTAG and UFI Box. If the bootloader is locked, users may not be able to perform tasks like flashing custom firmware or rooting the phone. With direct access to the device's motherboard, these tools can unlock the bootloader, allowing users to gain full control over the device.
Bypassing FRP (Factory Reset Protection):
- FRP Bypass is another critical feature. FRP locks devices after a factory reset to prevent unauthorized users from accessing the phone. If the device is stuck on the Google verification screen, Easy JTAG and UFI Box can bypass FRP protection by directly interacting with the phone’s system files and bypassing the Google account verification process.
Flashing Firmware:
- Flashing firmware is another key function that these tools provide. Whether it’s for restoring a corrupted system partition, downgrading, or upgrading the device's firmware, Easy JTAG and UFI Box can flash the appropriate firmware files to the device’s eMMC or UFS storage directly.
Unbricking Phones:
- Unbricking a Phone: If the phone is bricked—either due to an unsuccessful firmware update or corrupted bootloader—ISP tools like Easy JTAG or UFI Box can revive the device by reprogramming the eMMC or UFS chip and reinstalling the operating system.
Repairing IMEI:
- IMEI Repair: Another common use for tools like Easy JTAG and UFI Box is IMEI repair, especially when the IMEI has been corrupted or wiped. These tools can restore the device’s IMEI number, which is essential for ensuring that the phone functions correctly on mobile networks.
5. Hardware Required for ISP Tools
Both Easy JTAG and UFI Box require specialized hardware to connect to the device's motherboard. Typically, these tools include:
- Main Interface Box: This is the core hardware that connects to the computer via USB. It contains the necessary ports for connecting to the device.
- Cables and Adapters: These include specific connectors (e.g., JTAG cables, eMMC adapters) that connect the ISP tool to the device's motherboard.
- Power Supply: In some cases, the device will need an external power supply to allow the ISP tool to interface with it.
For Easy JTAG, you would typically use a USB cable to connect the JTAG box to the phone's mainboard using specialized cables that connect directly to the test points on the motherboard.
For UFI Box, similar cable setups are required, though the tool often comes with adapters for different chip types (eMMC, UFS, etc.), which make it versatile for various types of smartphones and tasks.
6. Procedure for Using Easy JTAG and UFI Box on Honor Devices
