| Step | Description | Metrics Collected | |------|-------------|-------------------| | 1. Baseline measurement | Record download time, success rate, and CPU/memory usage for the official installer (v2.0.3) across three network conditions (LAN 100 Mbps, Wi‑Fi 30 Mbps, 4G 15 Mbps). | Avg. time (s), success % | | 2. Bottleneck analysis | Use Wireshark and Process Monitor to locate latency sources (DNS lookup, TLS handshake, chunked transfer). | Latency per phase (ms) | | 3. Prototype modifications | Implement four targeted changes (see Section 4) and repeat measurements. | Δ time, Δ success % | | 4. User‑testing | Recruit 12 participants to perform a flash using the original and modified versions; collect SUS (System Usability Scale) scores. | SUS score | huawei flasher v2 download better
All tests were run on Windows 10 22H2, Intel i7‑12700H, 16 GB RAM.
| Condition | Avg. Download Time (s) | Success Rate | CPU Avg. (%) | |-----------|------------------------|--------------|--------------| | Official – LAN | 78 | 92 % | 18 | | Official – Wi‑Fi | 142 | 84 % | 22 | | Official – 4G | 215 | 71 % | 27 | | Modified – LAN | 62 | 98 % | 15 | | Modified – Wi‑Fi | 115 | 95 % | 18 | | Modified – 4G | 168 | 90 % | 22 |
The modified version reduced download time by 20‑30 % and increased success rates by 10‑20 % across all network types. SUS scores rose from an average of 68 (marginal) to 82 (good). The “better” version means:
Even the best modded tool can have issues. Here are solutions:
Problem 1: “Device not found in download mode”
Fix: Install the Huawei_Download_Mode_Driver (included in the better package). Then use Zadig to replace driver with WinUSB.
Problem 2: Flashing stops at 97% – “Sahara protocol error”
Fix: This is a USB power issue. Use a powered USB hub or a laptop with battery. Also, reduce Max Payload Size to 0x20000. Recommended sources (trusted by XDA & GSM forums):
Problem 3: “Partition cust not found”
Fix: Your firmware doesn’t match the device’s region. The better version has a “Force Cust Ignore” checkbox. Enable it.
Problem 4: Bootloader relocks after flash
Fix: Before flashing, go to Settings > OEM Unlock (if accessible). Or use the “FRP Bypass” button in the better tool before writing firmware.
