Motorola Edge 50 Fusion (Model: XT2429-4) Repairing Dead Boot or Hang-On-Logo

Repairing a dead or hang-on-logo Motorola Edge 50 Fusion (Model: XT2429-4) requires advanced hardware level servicing, specifically involving the reprogramming of its UFS storage chip. When a device experiences a corrupted partition table, failed over-the-air (OTA) updates, or bad firmware blocks, it often falls into a dead boot state (showing no signs of life or Qualcomm HS-USB QDLoader 9008 mode) or gets stuck indefinitely on the startup logo.
Below is a comprehensive technical guide and overview for mobile software technicians on using a UFS Dump file to revive this specific device using professional hardware programmers.
Motorola Edge 50 Fusion (XT2429-4) Specifications:-
Before initiating chip-level work, it is essential to understand the underlying hardware architecture of the Motorola Edge 50 Fusion (XT2429-4) to configure your programming software accurately.
    • Codename: Cusco / Cuscoi
    • Processor (CPU): Qualcomm Snapdragon 7s Gen 2 (4 nm)
    • Storage Type (ROM): UFS 2.2 storage chip
    • RAM Configuration: 8GB / 12GB LPDDR4X
    • Operating System: Android 14 (Hello UI)
    • USB Connectivity: Type-C USB 2.0 (supports OTG and Qualcomm EDL interface)

Symptoms of UFS Corruption in XT2429-4:-
    • Hang on Logo: The device freezes on the initial Motorola boot screen and refuses to proceed to the system animation.
    • Dead Boot / Auto 9008 Port: When connected to a PC via USB, the device does not vibrate or light up, but the device manager identifies it instantly as Qualcomm HS-USB QDLoader 9008 without any key combinations.
    • Fastboot Bootloader Errors: The screen boots directly to a critical error mode displaying message blocks like “boot failure” or “baseband error”.

Step-by-Step Reprogramming Process via EasyJTAG Plus or F64 Ultra Box:-
Technical Disclaimer:- This procedure requires micro-soldering experience (IC Reballing) and professional equipment. Proceed with caution to avoid permanently damaging the logic board.

Step 1: Download the Tested UFS Dump File
You need a reliable, verified dump file extracted from a working XT2429-4 unit. Ensure the firmware version of the dump matches or is higher than the version previously installed on the dead device to avoid anti-rollback issues.
Required Files:- LUN0, LUN1, LUN2, LUN3, LUN4, LUN5.

Step 2. Chip Desoldering & Preparation:-
    1. Disassemble the device and safely remove the motherboard.
    2. Apply high-quality flux around the UFS chip. Using a hot air rework station (set to roughly 340°C–360°C depending on your station), carefully desolder the UFS chip from the PCB.
    3. Clean the black glue and remaining solder pads on both the motherboard and the UFS chip.
    4. Reball the UFS chip using a dedicated UFS BGA stencil.

Step 3. Programming via EasyJTAG Plus / F64 Ultra Box:-
    1. Insert the reballed UFS chip into the compatible UFS socket of your programmer (EasyJTAG Plus or F64 Ultra Box).
    2. Launch the box software (e.g., EasyJTAG Plus UFS Tool Suite or F64 Tool interface).
    3. Select the correct voltage settings (typically VCC = 2.95V, VCCQ2 = 1.8V) and click Detect / Check UFS.
    4. Wiping the chip without a backup permanently destroys the IMEI, network signal, and Wi-Fi. A generic dump file will boot the phone, but the unique security keys will be gone forever.
    5. Read/Backup Essential Partitions:- modemst1, modemst2, fsg, fsc, persist, hob, dhob.
    6. Ensure the chip logs read successfully, noting the storage size and health report (Health Report should read Normal or 0%–10% used).
    7. If the chip has bad sectors or a corrupted partition table, perform a UFS Wipe / Erase.
    8. Go to the “Write” tab, load your downloaded XT2429-4 UFS Dump, and allocate the LUN files to their respective slots.
    9. Click Write and wait for the verification process to finish successfully.

Step 4. Final Reassembly and Flashing:-
  1. Remove the chip from the socket and re-solder it onto the Motorola Edge 50 Fusion motherboard.
  2. Allow the board to cool down completely, re-seat it in the chassis, and plug in the battery.
  3. The device should now boot into Fastboot Mode or show a charging icon.
  4. Finalise the repair by flashing the official Motorola stock ROM firmware using the Motorola Rescue and Smart Assistant (RSA) Tool or standard fastboot commands to rebuild individual security partitions (modem, fs, persist) unique to the device.
