It looks like you're asking for a guide related to the Tecno CI6 device — specifically something about "DA file" (Download Agent) and "new" version.
However, there is no widely known Tecno model called "CI6." The most similar models are:
It's possible you meant:
Below is a general guide on finding and using a DA file for Tecno phones (specifically for SP Flash Tool), including what to do if you have a newer/unknown model.
Install Drivers: Run MTK_Driver_Auto_Installer.exe. Reboot PC. (Disable driver signature enforcement on Windows 10/11). tecno ci6 da file new
Launch SP Flash Tool: Run as Administrator.
Load the New DA File (Crucial Step):
Options > General.TECNO_CI6_DA_new.bin and select it.Load Scatter File: Click Scatter-loading and select the MT6580_Android_scatter.txt from your firmware folder.
Configure Flash Mode:
Format or Download depending on need.Firmware Upgrade.Download Only and uncheck userdata and cache.Connect the Device:
Execute Flash:
Download. The red progress bar indicates DA handshake.Success: A green checkmark + "Download OK" appears.
Even with a new DA file, issues arise. Here is the debugging matrix: It looks like you're asking for a guide
| Error Code | Meaning | Solution |
|------------|---------|----------|
| S_BROM_CMD_DA_SEND_FAIL (0x13BE) | DA incompatible or corrupted | Try a different "new" DA source. Ensure no DA checksum. |
| S_DL_GET_DRAM_SETTING_FAIL (0x13BE) | Preloader mismatch | The DA cannot initialize DRAM. Flash preloader separately first. |
| ERROR: STATUS_EXT_RAM_EXCEPTION | Hardware conflict | Downgrade SP Flash Tool to v5.1928. Newer tools sometimes cause this. |
| DA_HASH_MISMATCH | Secure boot lock | Use MTK Bypass Utility before flashing. The "new" DA lacks valid hash. |
Before proceeding, confirm your device model. The Tecno CI6 corresponds to:
Important: Do not use DA files for Tecno C6, C8, or other CI-series (like CI7). The DA file is often chipset-specific but also has bootloader handshakes tied to the exact model.
The keyword "new" is critical. Older DA files may fail due to: Tecno Camon i6 (or Camon i6x) Tecno Spark series
Using an outdated DA file on a new Tecno CI6 stock ROM will often result in a DA HASH Mismatch error. Hence, you need the latest Tecno CI6 DA file (version V8 or higher, typically labeled MTK_AllInOne_DA_v8.bin or specifically tuned for CI6).
