The blocking of reading and writing of SPI flash regions can be considered removed. Starting at address 0圆0, we need the byte sequence to be 00 00 FF FF 00 00 FF FF:Įdit, save, close hexit and write the region descriptor back to the SPI flash: The len.bin file that we received is the descriptor region, it is it that contains the bytes that do not allow us to read the SPI flash in normal mode. If the program scolds about the impossibility of reading, then you did not close or did not keep the contacts closed. After loading the laptop, who is where, and I am in dos, run fpt with the keys:Īs a result of the fpt program, we should get the len.bin file. The above contacts will need to be closed before turning on the laptop, I do this with sharp tweezers, and then, after turning on the laptop and waiting for the POST procedure, the contacts can be opened. Without disconnecting the cable, we slide the keyboard towards ourselves in order to get access to two contacts near the chipset.

We lift it up carefully so as not to damage the cable connecting the keyboard to the motherboard. Click on the keyboard and move it away from you. We unscrew the screws indicated by the keyboard icon: one under the cover that covers the memory and the wifi card the other in the battery compartment.

Read the hardware maintenance manual for the t420s laptop to remove the keyboard. In addition to FPT, to edit the firmware, we need a hex editor, for example hexit, which, in the case of using a bootable dos flash drive, must be written to this USB flash drive along with the FPT version for dos.īut we still have to work with a screwdriver, and also with sharp tweezers (this is it in the introductory picture), since all SPI flash regions are blocked from the factory on our test laptops, except for the BIOS region, so our first task is to unlock the reading and writing of the ME region.įor Lenovo, unlocking will be easier. I usually use the HPUSBFW_Special program for this, which is easy to google, and you will need to google a set of dos files to it.

For those who do not like fun in the form of programming a "screwed up" flash drive with a programmer, to minimize risks, it is advisable to use the FPT version for dos, which means that you will need to create a bootable USB flash drive with this same DOS.

In all packages "Intel ME System Tools" FPT is present in dos, windows, windows 64bit versions.
#Intel flash programming tool fptw64 download
For Lenovo we download the package "Intel ME System Tools v7.1 r3", because as it is "For 6-series systems which come with ME firmware v7.x", and for Dell we download the "Intel ME System Tools v9.0 r2 ", By the way it is" For 8-series systems which come with ME firmware v9.0.x " The easiest way to get these tools is from this site. To access the SPI flash we will use the flash programming tool FPT, which can be found in the Intel ME System Tools package.
#Intel flash programming tool fptw64 update
It has many regions, in particular, the BIOS region, the one that we update most often by downloading it from the manufacturer's website and it also has a ME region that uses the Intel ME controller, which in turn implements AMT. In modern computers, a BIOS chip is a so-called SPI flash. "Bios" is written in quotes because it is not really a bios. And it is this firmware that we will correct to enable AMT.

Its main component, the controller, is built into the chipset, and the controller firmware is in the BIOS. Intel AMT is based on Intel ME, a subsystem built into modern computing platforms. I deliberately indicated chipsets and processors, because to support AMT, they both need to support vPro technology. Test subjects will be a Lenovo t420s laptop with a Core i5-2520M processor and a QM67 chipset, and a Dell Latitude e6450 laptop with a Core i7-4800MQ processor and a QM87 chipset. remote control technology at the hardware level, but for some reason blocked by the manufacturer. I got my hands on the second laptop supporting Intel AMT, i.e.
