Hello.

ERROR[008]: Unknown flash device. Device No:ID = 0:00000000.

There can be two reasons of this error - device has HW issues or the problem is with connection.

i have molex flex cable tested on other model , i post log here :

Please solder all JTAG wires manually, don't use molex cable. Make each wire as short as possible (max. 3-5 CM length) and try to connect again. Try to connect with and without fully charged battery. Also, try to connect with different JTAG Speed values.


If the problem is still the same, most likely, your device has HW problem.

Also, please look here:

thank you ,
molex flex cable is tested with i747m and all is OK , when i do all parameters "AUTO" software Medusa PRO detects and gives " device unsupported" , the log is with medusa software ;
my question is it supported via EMMC or JTAG ?

[Medusa Box]

Repairing of Samsung GT-I8730 is supported via JTAG in Medusa Software. As I have written above, solder all JTAG wires manually and try to connect.

when i do all parameters "AUTO" software Medusa PRO detects and gives " device unsupported"

Select "Qualcomm MSM8930" and post here Medusa Pro Software log with connecting procedure.
