回答“Whispernet Simcard change”Generally hardware hacking works when generic, commodity hardware is used for single purpose (ie SIM cards for ebook downloading). On the Kindle this is custom hardware. It very specifically avoids competition with smart phone and tablet manufacturers and Whispernet with cell signal providers, yet still provides unlimited, forever book downloading. Basically for Amazon's custom variations on PDF files. Rab77hp provides the hardware answer for this, but I wanted to provide the “design” rational. This business model has to defeat any hardware hacking absolutely. My first thought when these came out was: how could I hack it to get free, unlimited texting usage? Kinda the mirror image what you're hoping to do. Neither be done, at least not without spending much more money and time than buying a new smartphone or tablet and paying for a cell signal provider.
回答“The bios write protection for a Samsung XE500C21 can be removed?”For technical information https://www.chromium.org/chromium-os "From MRChromebox.tech ChromeOS Device Firmware The firmware used by ChromeOS devices is built around serveral open-source projects, and consists (mainly) of a hardware init component (coreboot) and one or more payloads (depthcharge for Verified Boot and ChromeOS, SeaBIOS for Legacy Boot Mode) which are subsequently executed. The firmware resides on an SPI flash chip… The shaded sections at the bottom are read-only, which is enforced by the firmware write-protect screw on the main board" Actually on this model, I believe there’s a switch under a panel on the side to get into Developer Mode. This will also erase the SSD. Also Chrome OS partition layout is crazy, with about a dozen partitions. It only gets more complicated from there. Have you looked into Crouton?
回答“How do I install Windows 10 on the Samsung Chromebook?”Get into Developer Mode as described in https://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices/samsung-series-5-chromebook Download firmware from MrChromebox.tech. There’s more instructions there and elsewhere on the web, even another site or two for the boot firmware. (try Github) But I’m going to stop there, because the solid state drive is far too small to do anything useful with Win10, or nearly any other operating system. It’s painfully slow and buggy. You might try Gallium linux, or Chromium (the open source version of ChromeOS), but still… this is mainly learning exercise, and a bigger hazard than bricking, because; Yes, its doable, but the results are disappointing. Fortunately this Chromebook is cheap enough compared other notebooks that you might want to try it, but don’t expect premium online games to work.
