1. Hard Brick: The device shows no signs of life (no vibration, no screen, no recovery mode).
2. Preloader Corruption: The initial bootloader is damaged, preventing normal flashing.
3. Bypassing Locks: In some cases, it is used to bypass FRP or user-locked SP Flash Tool errors (e.g., ERROR 4032, 5054).
4. Downgrading Firmware: When higher-level security prevents rollback.

Here is the exact location for the JMMAL10 Test Point: Hard Brick: The device shows no signs of

B. Voltage Threshold Adjustments

• Previous Setting: Test points were monitoring a 0.5V - 4.5V range.
• New Setting: The acceptance window has been tightened to 0.6V - 4.4V to detect marginal sensor failures earlier.
• Impact: This allows the system to trigger a "Derate" warning sooner, preventing potential damage to after-treatment components (DPF/SCR).

Important Considerations

| Purpose | Is Test Point Needed? | |--------|----------------------| | Unbrick (Qualcomm 9008 mode) | ✅ Yes | | FRP / Huawei ID bypass | ❌ No – use HCU, DC-Unlocker, or PotatoNV (Huawei USB COM 1.0 mode) | | Factory reset / update via HiSuite | ❌ No – use Recovery or Fastboot |

Unlocking the Secrets of the JMMAL10: A Guide to Test Point Update (TPU)
