Ok, I got a couple more ideas. Did you check to make sure, when flashing with an evox based flasher, that the 004B is located in the evox.ini as a flash type?
Yes... Flash = 0xbf57,"SST 49LF002B",0x40000
post, as this post indicates this as a possible issue and also that there could be a misconfiguration on the chip itself, such as a misplaced solder blob.
There are no solder blobs on the chip that could be misplaced...I would like to know which pins are connected before and after the solder connection is moved... (Look here!
) If someone could check whats the difference between those two different situations by using a multimeter maybe I could reproduce this with my DuoX3... (I hope you can understand this...I don't know how else to explain what I mean...)
Also, some modchips had a feature where you had to turn the xbox on a certain way to disable flash protection, such as holding the power button for longer than one second when powering on. The front light on the xbox would glow yellow or red to indicate that write protect was turned off.
Tried that too...Holding Eject and/or Power button for long time, pressing both at same time....tried everything...
Sorry, but had that ideas already...
Meanwhile I got the feeling that the Lattice controller chip has been misprogrammed...It has been programmed to work with the SST49LF020A. With that changed circuit you talked about (misplaced resistor/solder blob) I think it could be possible to get it working but I don't know anyone who got a modchip like that one to check the circuit before and after the changes... -.-This post has been edited by Milka2009: Jan 8 2012, 04:42 AM
