bean reading up and found this guys
Unless you already know, you can just run
"nandpro usb: -r1 test"
You'll get the flashconfig:
01198010 - Xenon, Zephyr, Opus, Falcon
00023010 - Jasper 16mb, Trinity
008A3020 - Jasper 256mb
00AA3020 - Jasper 512mb
Note - it's possible to have a BB Controller on a 16MB Jasper.
If you are STILL completely clueless as to what board you have (or want to make sure your Jasper is def correct), dump 64MB. Don't worry, it's the biggest size you would need and ensures that regardless of the console you have, you will have a full dump. Use this command:
"nandpro usb: -r64 nand64.bin"
Open the nand64.bin in 360 Flash Dump Tool. If it opens, great.
If not, you MAY need to manually remap blocks in the first area of the NAND. Post a help topic at this stage if you need assistance.
360 Flash dump Tool should tell you what console you have in the bottom right corner.
(Assuming your CB value is glitchable)
Zephyr / Falcon / Opus - re-dump as follows:
"nandpro usb: -r16 nanddump.bin"
Jasper - unless you are 100% sure you have a Big Block Jasper (256/512MB onboard MU), in 360 Flash Dump Tool, open your nand64.bin and click on Tools/Edit Config.
If you see PROPER data in there, you're good to go. rename nand64.bin to nanddump.bin.
If you see a page of FFFFFFs etc, you have a 16MB jasper and you can re-dump using the above -r16 command.
You can NOW program your CR based on your board type. Go ahead and install the CR.
