Place the files you want to flash your cpld with next to the executable. Squirt team recommand to use rgh_corona_minusone_nr(suggested).svf , but if you don’t have good result with it, you can try another one. Then use the following commands : cable ft2232 detect svf yourfile.svf B : Coolrunner Use your nand-x and nandpro 3.0, place de xsvf file you want to flash next to nandpro 3.0 and use the following command : nandpro xsvf: yourfile.xsvf II : Making the hacked image -Use this diagram to solder your nand dumper - Dump your console’s nand twice usinge Jrunner or nandpro 2.X (nandpro usb: r16 (or 64): nand1.bin): nand1.bin) and make sure they match (fc /b nand1.bin nand2.bin) - Use Xebuild Gui 2.081 to make the ECC image. - now flash the ecc image with nandpro and the +w16 command (nandpro usb: +w16 image.ecc) (i used squirter program, but Jrunner or nandpro 2.X is fine too) III : Soldering the hardware RGH corona Diagram (open in new window) IV : let’s glitch A : Make the console boot Connect your 360 to your TV, plug the power supply and the network cable, turn it on. XeLL doesn’t boot with any video So once you see the debug led stop blinking, it’s the console has booted . If you don’t have boot at all, check your soldering, play with the CPU_RST length or you can try other jed/xsvf files. B : Grab the key Once the console has booted, go back on your computer and launch Xebuild GUI 2.081. In Tool, use the scan for XeLL features Put 0-100 in scan range and press Start scanning for Xell After a few, you should see this =) Now you can build your Freeboot image, be sure to select RGH 2.0 - Flash it with your favorite software with the -w16 command Full credit goes to - Tiros & GliGli for their original RGH work - cOz for his universal SMC patcher - Squirt360 Team - Xecuter Team - Nice69 for the onboard Oscillator founding

THE HACK IS MADE AVAILABLE SO YOU CAN HAVE A PLAY WITH THIS YOURSELF AND SEE WHAT RESULTS YOU CAN ACHIEVE. THIS IS WHY WE DESIGNED THE COOLRUNNER 3, IT HAS BEEN FINE TUNED USING A MUCH MORE ADVANCED DESIGN AND GLITCHES VERY RELIABLY AND VERY FAST. WE DO NOT OFFER ANY GUARANTEES OR SUPPORT WITH THE XC264A CORONA HACK. WARNING*********WARNING*********WARNING*********WA RNING********* To get this working on CoolRunner Rev A B or C you simply have to add a 48.000MHz crystal. If you have Rev A or Rev B remember to remove C15. It's a bit cheap and cheerful and the hack isn't that good with the limitations of the older gen XC264A hardware but here it is anyway. The crystal has to be good quality - not some cheap crappy one as it will not work. These work very well: http://ie.farnell.com/jsp/search/pro...sp?SKU=1640968 48.000MHz crystal wiring to the CoolRunner: PIN 1,4 to 3v3 PIN 2 to GND PIN 3 to B We have included 6 files with different timings tx_corona_0_2.xsvf tx_corona_0_3.xsvf tx_corona_1_2.xsvf tx_corona_1_3.xsvf tx_corona_2_2.xsvf tx_corona_2_3.xsvf The most important point is the CPU_RST - this will make the difference between a 30 second glitch and a 30 minute glitch. You may want to try using the CPU RESET CLEANER addon that we released - it works very well with RGH1 and RGH2. We also recommend you try the different wire layouts as per the original CoolRunner instructions. CoolRunner 3 is in production right now - you will get to see how Slim glitching should be done Thanks to GliGli & Tiros for the original RGH exploit. - Team Xecuter On a side note.... These are the crappy glitch times you should expect (measured with the CoolRunner 3 RATER) These are cycles - not seconds (1 cycle = 5 seconds). In our opinion it just isn't worth paying for - so we encourage you not to buy a CoolRunner REV C or any other XC642A based glitcher just to do Corona - you will probably be dissapointed. 11, 51, 14, 5, 5, 26, 19, 1, 1, 13, 18, 3, 1, 3, 4, 6, 8, 5, 5, 9, 3, 2, 7, 22, 14, 4, 6, 5, 1, 2, 16, 2, 5, 17, 8, 10, 8, 8, 9, 4, 13, 2, 9, 4, 19, 2, 8, 2, 10, 11, 1, 14, 1, 2, 10, 4, 3, 3, 3, 1, 3, 20, 4, 4, 6, 15, 7, 3, 18, 3, 6, 6, 1, 2, 3, 11, 2, 37, 3, 13, 1, 10, 9, 4, 10, 6, 3, 14, 2, 4, 4, 4, 6, 4, 2, 1, 6, 1, 9, 3, 4, 2, 8, 2, 5, 15, 3, 3, 1, 2, 6, 7, 6, 21, 15, 27, 11, 9, 4, 10, 2, 5, 11, 3, 6, 14, 26, 8, 2, 5, 4, 3, 11, 3, 15, 4, 10, 13, 14, 22, 22, 9, 6, 22, 19, 1, 5, 10, 5, 1, 7, 2, 16, 9, 1, 11, 2, 7, 24, 3, 8, 12, 8, 7, 12, 13, 4, 7, 3, 1, 17, 9, 2, 5, 3, 2, 5, 1, 16, 4, 9, 9, 3, 1, 1, 15, 18, 3, 7, 3, 49, 18, 9, 6, 4, 1, 2, 11, 1, 3, 1, 5, 14, 12, 16, 11, 1, 8, 11, 1, 47, 8, 1, 19, 2, 18, 9, 6, 7, 15, 12, 13, 6, 16, 5, 3, 11, 3, 12, 2, 5, 2, 11, 4, 1, 18, 8, 13, 8, 10, 8, 1, 1, 13, 10, 5, 38, 10, 20, 3, 8, 4, 7, 4, 17, 3, 6, 1, 8, 13, 2, 3, 2, 10, 1, 1, 30, 17, 7, 14, 24, 10, 1, 16, 11, 16, 5, 6, 6, 11, 6, 1, 15, 1, 3, 5, 25, 10, 7, 5, 13, 12, 6, 8, 5, 7, 1, 46, 2, 17, 14, 2, 2, 6, 3, 3, 2, 5, 23, 3, 1, 8, 23, 15, 5, 1, 3, 3, 3, 1, 2, 5, 10, 9, 9, 20, 7, 22, 1, Xecuter_DIY_Corona16_Coolrunner_Upgrade.zip

The XeBuild team has released an update to their Xbox360 nand builder, XeBuild 1.04. Along with some minor bug fixed they have also added support for the Corona motherboard. There is no need to update your current nand images as the fixes are minor. xeBuild_1.04.zip 15574.zip
