Re: Dlink Modems Firmware Dump Promblem

fist you need to bring the firmware back to what it was. Use a TTL to hook up to those pins. Try to clear the nvram and see what that gives.

Re: Tefal GV8962 Pro Express steam iron - no power

I think C7 may be shorted too. Take it out and remeasure it out of circuit.

Re: Tefal GV8962 Pro Express steam iron - no power
