Without specific information on mtksu , it's hard to provide direct solutions. However, errors during critical init steps often relate to:
They staged the software patch, tested it across multiple boards and conditions—including deliberate EMI injection and concurrent firmware updates—until the error no longer reproduced. In the postmortem, the team updated their validation matrix to include cross-board interference scenarios. The “failed critical init step 3: HOT” entry became a lesson: safety-first boot sequences are blunt but essential; coordination between firmware timing and hardware behavior matters; and the smallest coupling can cascade into a system-wide fail-safe.
Verify if your device is 64-bit or 32-bit. You can check this by running getprop ro.product.cpu.abi in an ADB shell.
The system didn’t just crash. It threw a kernel panic.
Directly use a USB 2.0 port on the motherboard—USB 3.x ports and hubs add hubs which can break the timing. A $5 USB 2.0 hub between the PC and phone can sometimes stabilize the signal.
