HARD-BRICKED RECOVERY REPORT
My scope was alive last night after many effort in hardware and software related recovery
1. Replaced 2 Opamp U24+U27 by AD797 smd (temporary). Scope was booted ok but hung as before.
2. Install Adb fastboot device driver (the most important step after FEL driver)
3. Platform-tools to restore filesystem
4. Update fix and lastest fw
5. Restore backup (any backup upk) but showed red error code -3 (DavidAlfa pls help me...
)
6. Calibrate ok
7. Scope was rescued. Test functions and accuracy ok.
8. Test bandwith, limited ~ 4-5MHz due to AD797's bw but for audio hobby it's still ok.
9. Replace LMH6702MA later if I find any genuine parts.
