"Request: itel A06 A669W pac file to fix FDL2 unsupported error".
05-08-2026, 11:30 AM
Device Model: itel A06 (A669W)
Chipset: UNISOC SC7731E
Tool Used: SPD ResearchDownload / UpgradeDownload R26.21.2801 & SPD FactoryTool R27.25.4601
Firmware File Loaded: A669W-SA375AB-UGO-OP-250522V1750
Issue Description:
When attempting to flash the firmware .pac file using ResearchDownload, UpgradeDownload, or SPD FactoryTool, the initial handshake starts on Port 7, but the process fails right after the FDL2 stage with the following error:
Step: FDL2 | Status: Finish | Progress: not supported this feature [Unsupported Command]
All backup options (NV_W, ProdNV, PhaseCheck) have been unchecked in the settings tab, and standard baudrate adjustments have been made, but the hardware BootROM continues to reject FDL2.
Could you please provide a modified generic loader_fdl file or a compatible, tested PAC file for this build? Thank you.

Try a lower version of Research Download tool like R23.19.3301
