Dear all,

I have bin measuring at this device.
I noticed that when the On/Off button is pushed the device takes about 10mA from the battery/power supply for about 3sec and then goes back to 0mA again.
Do I have problems with the processor? could this be firmware? or could something else be broken??

Thanks

If only firmware problem, (e.g defective bootcore) then you have 23-26 mA.
But this value can come from the Adressbus too....

10mA lets think....
If you have shematics and a oscilloscope or a multimeter to measure...
...may the sticky threat "Signal/part descriptions" help you....

10 mA can couse from not working dialog or not working rf-chip (26MHz!!) - this results in a not working processor.

Flash Type: FFFF
Original IMEI: 94EEC.-..-......-.

Flash Type is not supported.
