Hi,

Was looking at the other thread with only pictures and had a couple little questions
Btw, the more i find out about the bcusb the more i think that little thing is amazing

If i want to read the nand on my jasper 512mb , do i use the nand 1.07 fw or do i use spi ?

and do i use the spi pinout shown in another tutorial ?

thanks
 
been looking at spi pinout and connection to xbox pics, and the points are named totally differently, and only 6 on bc usb and 7 in the phat connection pic....
 
You would use the NAND 1.07 firmware . The only connection on the BCUSB pinout that is not used is the KSK pinout , all the other pinouts connect to the board.
 
k, thanks

any idea where i can find the pinout for the xbox, cuz the name of the bcusb pinout doesn`t match the pinout numbers on the xbox...
 
The xbox is detected just like in your thread with the pictures, same chip, but the xbox script isn't loaded and i've looked in the directory, it isn't there

im using nand-spi 1.07 and blackcat usb build 326

thanks for your help
 
also when i try to read the nand the bcusb app crash with an exeption : system out of memory
 
I removed the script , due to the fact that there was issues with it , mainly regarding the writing of the .ecc file , as it could not be done on the BB boards , it is in one of the posts on the forum somewhere .
Does the app crash straight away ? Reading a 512 nand could take a long time upwards of 30 minutes . You only need to read the first 64MB (if i remember correctly) so if you use the script it should be able to do that for you .

Found the script , before you write anything to your xbox verify your dumps are correct.

by changing the adress i was able to read the chip, i guess the full chip cannot be read,
can i use the script for the 16mb in the script area ?
cuz i did not find another 1 and i don't know the proper addresses i need to do a good backup (so the 1st 64 mb is what i need ?)

sorry if the questions are stupid, i can't find much info on using the blackcat to do this

also
 
The full chip can be read , but it takes ages to do , and as it is not needed it is pointless , you only need the first 64 , the process is similar to other devices except of course you are using the BCUSB.
When you read the first 64 , test the dump in the J-Runner app to see if your nand dumps open and are identical.
 
i see, does it have to be precisely 64mb or can i read 65-70mb (same thing 2x and compare those)

the tutorial i found show with nandpro, i tryed but it does not recognise the blackcat
 
The settings i have in the script for reading and writing are correct , do a read of the first 64 and put it in j-runner if it loads and gives you some info then you will know it is correct.
BCUSB will not work with Nandpro , you will need a compatable device that works with nandpro to load your .ecc file as BCUSB can not do that properly.
 
Works good, i had found the proper size and done 2 matching dumps now doing 2 more with your scripts ( will have 4 , exact same size)

so if i understand correctly, i can use the script to write the modified dump back, what was the write ecc for ? only writing the ecc to the specific adress ?
 
You need to get the .ecc file made for your specific box ,, this allows you to load Xell onto the box to get your CPU key.
You can use the script to write the dump back (not the .ecc) .
The write ecc on the script only works for the 16MB boxes.
 
script hangs, pressed the Read for the 64mb 512 it read to 100% and started a second time and now it hangs at 100% after finishing to read, has not saved the dumps ...
 
so instead just gonna use the read and write , i just need to read the 1st 67 108 864 and then write back the same
 
Try this script , i have removed the verify option.
