Re: es720 - update firmware: - LSR Firm Update Failed

Losing power during a update is a bad thing..1st thing I'd try is to find a much older firmware version (1XX) and try to update using this, then step up to the latest version. If this fails then the recovery jigs are your next line of defense. But the power loss may have damaged the SYS bd. You may have to replace it. Emujo

just to check, is the engine and the laser the only things which fail the firmware update>? everything else works fine.

Just to add to EMUJO's post, these SYS pcbs can be very touchy - if the SYS & HDD updated ok, try updating the ENGINE & LSR individually ie ENGINE ONLY then LSR ONLY etc. Otherwise it may only be done by the Update Jig and thats not guaranteed either.
