| Code | Meaning | v480 Trace Action | |------|---------|-------------------| | 0x1A20 | Preloader not responding | Trace shows which USB interrupt was missed. | | 0x1A30 | SBC (Secure Boot Challenge) fail | v480 logs the nonce mismatch. | | 0xFC00 | NAND bad block detected | Trace shows physical block address. | | 0xFFFF | DA version mismatch | v480 reports expected vs actual DA hash. | Unlike basic modes, v480 runtime trace can save logs during the operation, not just after. If the phone disconnects mid-flash, the partial trace is already on disk. Look for runtime_trace_last.log in the tool’s directory. Part 5: Advanced Use Cases for Runtime Trace Mode v480 1. Bypassing SLA/DAA (Secure Level Authentication) Newer MediaTek chips use SLA/DAA. The v480 runtime trace mode exposes the exact challenge-response cycle. Advanced users can inject a patched DA by analyzing the trace for 0x9C01 (DAA request) and replacing the response in real-time via a script. 2. eMMC Bad Block Management When a phone shows “flash error 0xFC00”, runtime trace mode v480 will list the bad block Logical Block Address (LBA). You can then manually edit the scatter file to skip those LBAs – something impossible in normal flash mode. 3. Analyzing Dead Boot Connect a completely dead (no vibration, no PC sound) phone. Enable trace mode. If you see:
