    EmeraldKiwi got a reaction from maulemall in AMD once again violating power specifications? (AMD RX-480)   
    This is a pretty big blow for AMD. Everyone was looking forward to a great value card, and all the reviews I have seen are really positive, and emphasize the value of the card. Unless AMD has a really good response to this, then the product will be kind of DOA.

    EmeraldKiwi reacted to GoodBytes in Microsoft confirms that July 29th is the last day for Windows 10 free upgrade - 119$ after that.   
    OEM is a license for system builders. It is intended to be cheaper to help keep the price of the system down.
    You have no 90-day (or whatever it was) free support to help you install Windows, and get started with Windows , you don't have the nice box, and basic manual, and you can't transfer your license to another system. It is locked to the first motherboard it is installed on. The exception, is that if the motherboard break, and you can't find the same one, Microsoft is willing to close its eyes and give you an override code to transfer the the license to another motherboard, but that is about it. So if you upgrade a computer for upgrading, then sorry, you need to buy a new license.
     
    Retail you have teh full package and all that, and you can transfer your license

    Well props to this guy. But holy cow that is a LOT of pixels. I guess we're just going to have to wait for Display Port 4725. Or HDMI 102874. Even then, we will need a GTX 9000000Ti to even push that kind of stuff.

    EmeraldKiwi reacted to Roawoao in FBI backs off of Apple   
    FBI are not going to be electrical engineering students taking FPGA/CPLD courses specializing in embedded systems design. Law enforcement != Electrical engineer. It might be hard for them to do it in house as I doubt many ECE students aspire to be part of the FBI.
     
    NAND emulation is trivial to the point where even modders can do it to things like a 3DS to spoof the operating system bypass software checks and the such. Hardmodded 3ds only require soldering skills and a customized SD card adapter to carry out NAND emulation. And since the older iPhone does not use PCI-e based flash storage the same/similar hard mod method can be done.
     
    I'll write a high level guide for you here if you want it requires good soldering skills and a strong technical background. Also if the boot loader doesn't mind a read only NAND it is much simpler since you can just block the writes in hardware.
     
    To start remove the NAND chip using hot air rework,
     
    See the exposed pads you are now going to use a dead bug style connection between your FPGA/CPLD dev board and the nand pads and system nand pads. You will want to downclock the flash memory as the signal integrity will be poor with all the wires keep things as close as possible and mount things to a block of wood/plastic.
     

    (Might even work the SD card transplant method) but note that the read only switch on an SD card does not enable a hardware read only protection.
     
    A full blown FPGA dev board is probably very excessive but it is going to be the most flexible solution something like (Digikey 220-1935-ND) LCMXO3L-6900C-S-EVN is probably sufficient. These are cheap so you can solder things directly to it and have the flash chip hot glued to the devboard.

     
    Then you want to go digging for datasheets and obviously you can figure out the Vcc/GND pins easily with a multimeter with micro test probes. If you can't find any public datasheets then take a sacrificial iPhone and do inline signal reverse engineering. Mike's electric stuff has done this on MIPI displays which are going to be much more complex than the flash protocol. Note that just watching the video isn't going to make it work for you as you need the hands on experience.
     
    I'm too lazy to dig up the datasheet but once you have the protocol down then you just program (Not as simple as it sounds) the FPGA to interface with say two NAND chips of the same make or use a DRAM buffer to have a ramdisk or even just do things on the fly and buffer things with a tiny SRAM chip as you really are not expecting much write activity other than the erase instructions which you could use to reset the iPhone. You could also get fancy and tie it into the touch screen controller and you can automate the PIN entries directly. (A second reverse engineering and the touch screen controller IC is going to be fairly simple to trick)
     
    Unless Apple pots the iPhone and adds tons of hardware anti-tampering stuff right down to the die level it will always be possible to attack the hardware especially if you don't really change anything but just want to peer in or emulate user inputs. Even the touchID sensor can be tricked using novel printing techniques. (This includes self destruct mechanisms, case tamper, ... which would affect reliability and useablity not to mention prevent any chance of repairing)
     
    I would not expect the FBI to have the technical and in house skills to carry out such a method. Apple if they were not being so difficult could just copy the NAND for them even easier since they have all the test/repair hardware and techs already. But obviously will not because it is bad PR to help the government break into a terrorists phone. Also Apple also probably has a whole pile of development phones/boards that have none of the production hardware security checks so they could also use those to run the erase disabled or many other possibilities. Tons of different things that Apple could do none of which would compromise overall security. Compared to a third party or university student, Apple has far more resources and pre-existing technical knowledge + hardware to assist and should be the first one a government agency approaches if they wanted help since they already have everything needed.
