Hi everyone at XBScene. I completely screwed an X360 trying to recover the DVD Key from it. Let me describe this issue with max details.
I got a Jasper from a friend with no DVD drive and no DVD key. So, I tried to recover DVD key using RGH (8955 dash). I got all the tools necessary (NAND SPI Flasher, Matrix Glitcher and all the necessary Files) and started doing it, following the GliGli tutorial. First, I made a dump from the NAND (Hynix 512MB) but, instead of dumping the whole NAND, I just got it from the first 64MB (according to the tutorial, it wasn't necessary to dump the whole NAND, that's why I just got 64Mb of it). My PC is running Win7 Ultimate (32Bits), with all updates and necessary files installed.
All wires were correctly connected ( I soldered pins to the points, so I coudn't get any unsoldered or cold solder points - and I'm very good at it). I started trying to use NandPro2.0e but it couldn't recognize the SPI Flasher (I got a message saying "ARM device not compatible with this version of NandPro"). Then, I only got it working with NandPro 20a (the one I ended up using).
I got 3 64MB-dumps from the NAND using Nandpro 20a. I made a safe backup from them, generate the ECC (following the tutorial) and dump it back into the NAND. Everything went out ok, responses similar to the ones described in the tutorial.
Then, I soldered the Matrix Glitcher to the board, turned the power on, but got no response from the console. Double checked the wires (everything was ok) and tried to turn it on a second time, with still no response (PSU LED just stays in Stand By - orange). Disconnected all wires and tried to Flash Back to original NAND. NandPro didn't recognize the NAND, showing the message "Could not detect flash controller". Double checked all connections (everything was ok) but I got the same results.
Since then, I have tried all methods from Internet (fast power the NAND, short 44 and 47 pins, alternate points, etc) but it has all been in vain (Nandpro can't access the NAND).
After doing lots of researches on the Internet, I figured out there's a way to read/write the X360's NAND, by using Progskeet (and I got the white one).
My doubts are:
1 - Are my 64MB-NAND dumps really of any trust? (I checked them using NandPro Fc command, latest version of XNandHealer and NandCompare with no differences)
2 - Progskeet only make full dumps from NAND. Is there a way I can "merge" (or correct) the corrupted NAND with the one I have? Are there any softwares for that?
3 - Still according to Progskeet, is there a way I can write my 64MB dump back to the X360? I think I only got a corrupted ECC, that why (I think) the console isn't powering on.
4 - Is still possible to recover the DVD key from it?
5 - Some people say the SPI is dead (that'd be why the NandPro is not recognizing the NAND), but where the SPI is located (inside the Flash NAND or in some circuit on the mainboard)?
Any help is really appreciated
Thx to everyone and sorry for my bad English, I'm from Brazil. =)
