Interesting that this one has a NAND whereas this one does not: It seem to have a NAND but different package. A better close-up picture with the chip markings visible would be nice. see here for close ups http://www.xboxhacker.org/index.php?topic=17149.0 |

I saw those. Can't see clearly. Is it "P57000-0 PHISCNUT1124A QK10W2D0"? |

It looks more like "PS7000-0 PHISON UT1124A QK10W2DD" to me. It's certainly manufactured by Phison as they have many similar products, I can't find this particular chip though.

Microsoft/Foxconn recently started manufacturing Xboxes in Brazil. I wonder if this new motherboard is specific to consoles made in Brazil or in China only.

Are the new matte black Slim 360's ok to glitch?

From what I understand its a bit "up in the air at" at the moment mate. Tempted to buy a second-hand slim (unless anyone has heard horror stories of them cooking like the phats) just so I know for sure the hack can be done. Bit early for us to know until more come into circulation and peeps like Blackaddr get their hands on one. My 4yr old phat died on me a month ago and was gonna treat myself to an early xmas present at the end of the month, but I doubt any of my local shops stock the old "shiny" one. I'm in the same boat as you mate.

Well. Blackaddr is attempting to move the timing of the glitch from the HANA to the SMC so if he is successful then the new Corona based Slim's will be glitchable.
Guess we will just have to wait and hope he is successful.

I really hope Blackaddr is successful. I just bought a Slim and its corona. I returned about 5 xbox's and the earliest one i could find was aug.6 with 9.6a power. Really sucks but at least i still have my zephyr with cooling mods.(Still loud as hell tho)

I've already got an accurate POST monitor running on the SMC. That might not sound like much but took a lot of work because you are taking complete control of the SMC for an extended period of time when it normally would be working with the CPU/HANA/ARGON for system config and init. But you can't simply take over and start monitoring a POST bit. If you don't reset the watchdog the SMC will halt, if you don't run certain service routines at the correct times (during early 2BL hardware init) you will halt the CPU. I had to find the registers that control the SMC I/O direction. I had to reverse engineer the I2C FSM and interrupt routine in order to control I2C from my own thread (it's not bit banged, it's a memory mapped peripheral).
None of the information above was available publicly (or to me privately) so it all had to be RE'd from scrach.
That said, my SMC post monitor can keep the system starting properly, and send I2C command to the HANA at the correct time, and I can see the clock frequency change. That might be enough to get a Corona working if necessary assuming the I2C bus is not exposed on the PCB (and using a CPLD for glitching) if they still use an abstracted I2C to configure the co-packaged HANA in the same way, I've only got a falcon to work with at the moment. Right now I'm just trying to get my head around the HANA PLL controls.
The problem at the moment is there is a limit to how slow you can set the CPU input clock (HANA controls clock INTO the CPU PLL, PLL_BYPASS controls frequency AFTER the CPU PLL or bypasses it entirely. On slims, we dont' bypass the PLL I believe, and PLLs have certain frequency bands they must be in after internal multiply but before divide). If the CPU input frequency is too low, the CPUs internall PLL won't be able to lock to it.
Also, it seems a single PLL controls four of the clocks coming out of the HANA, including CPU and PCIe. This bad because I can't lower the CPU clock frequency without lowering PCIe. I believe the PCIe bridge is configured and initalized in POST_2E, but if I drop the clock to low during POST_36 to slow the CPU, I think the PCIe links break and need their PLLs to be reset, not entirely sure.
So, lots of progress, lots of work still ahead.

After using a combination of alcohol and blackmail photographs, I was able to grab a brand new (sealed, boxed etc.) "shiny" slim 250GB. Getting it glitched once I can find someone in London (UK) who doesn't want to pull my pants down and lube me up on the price (hate soldering, its my achilles heel. I no longer live with my dad to fix my massive PS2 modchip blunders when I was a nipper lol). Kudos Blackaddr. Your posts are always informative and interesting. Keep up the work mate |

Microsoft/Foxconn recently started manufacturing Xboxes in Brazil. I wonder if this new motherboard is specific to consoles made in Brazil or in China only.
I messed around with some of those already. All DGD4 1071 (so far all MXIC ) and trinity board. (Brazil) |

Thanks for the update Blackaddr!
I sure hope it ends up being possible to glitch Corona Slims.

Picked up a 360 slim matt finish today in Tesco.
MFG Date : 2011-07-23
Serial ends with : 13005
As it says 9,6A on the actual XBOX can I assume that this is a Corona?

Yes, it's definitely a Corona. BTW, I wonder whether the 4GB Slim's have the Corona mobo yet. |

Yes, it's definitely a Corona. BTW, I wonder whether the 4GB Slim's have the Corona mobo yet. Thanks for the info. I returned the 250 and got a preowned 4gb from gumtree (with a 250gb hd) the 4gb has a matte finish and has a mfg date 2011-08-22 serial ending 13509 it is a 10.83A |
