Until very recently there were no reasons for downgrading Samsung ML-2160 firmware. To get rid from the chip you need to find the fix firmware, due to which the device would stop monitoring the chip what gives you an opportunity to stop paying for chips and refill cartridges for free. When Samsung released new ML-2160 V1.01.02.00 firmware, the situation changed rapidly. Samsung have decided to stop fooling around and began to sign new firmware versions with electronic digital signature (EDS), meaning not being able to install modified firmware without having the original Samsung EDS. It is impossible to pick or hack EDS, unless there’s a leak of EDS or should anyone find a weak spot in mechanization of the testing algorithm.

The firmware is signed with EDS using the secret (private) key, only Samsung has one. When being upgraded, the printer identifies the firmware with its own key that’s inside of the devise. These keys are different, asymmetric encryption algorithms are used. Having an open key it is impossible to get the closed one and upgrade the firmware, sign it and install it back to the printer. The signature is based on ECDSA, it is 512 bits, which means that it has to raise 2 to the power of 512, which is a lot and impossible.

But there’s another way, simpler. Using JTAG adapter you can connect to the processor, upload a boot of the previous firmware version without the EDC. Then, boot with no-EDC firmware version and install fix firmware.

Let’s get started. To fulfill our task we need the JTAG adapter. You can buy it at www.segger.com. Also, here you can find and download required drivers and upgrade your adapter’s firmware to the latest version. Also, there’s a more acceptable in terms of price option – you may go to aliexpress.com, but it is all about your personal preferences.

Adapter comes with a loop that needs to be prepared for the further process. Cut the loop in two, one half stays until you need it, the other is going to be processed. You need to clean up required wires, according to the pinout on the picture.

Silva s12 manual.pdf word mojo gold online for mac. We need following pins VTref, nTRST, TDI, TMS, TCK, TDO, 5V-Supply, Gnd. Next, solder it with hookup wires for more convenient connection with the formatter and label them not to get your “wires crossed”.

After the loop is done, you need to test the charging, +5 volts to the 19^th output of the loop. Switch the tester to the DC voltage mode and connect it between the 4^th and 19^th output. Turn on the commander. Say “power on” (without brackets). If you see 5 volts, that’s great. Say “power off” and 5 volts should be gone. If when powering the JTAG (commander) there’s 5 volts already on the 19^th output, you need to say “power off perm”, so you will have 5 volts disabled when it starts. Now when you connect the JTAG to the computer there will be no charge on the 19^th output.

Next, disassemble your printer and take the formatter board. Using JTAG output pinout and following photos solder corresponding outputs.

Let’s start with front side of the board. Connect outputs 1 (VTref), 19 (5V-Supply), and 4 (Gnd) according to the left side of the picture. Connect output 7 (TMS) to the processor pin 66, previously unsoldered from the board. Attention! The pin is very fragile you can easily tear it off. I was using slim tweezers and a soldering iron here. Hold a pin firmly with tweezers heat it with the iron and slowly lift it up. Next, solder a wire to it. You need to tape the wire to the board so the processor pin will stay in place while you’re ma the board. It is better to use bare varnished wire, it is more flexible, and you will prolong the output’s life. After your firmware is downgraded, you may not solder the output back to the board, everything will work just fine.

Now, the back side of the board. Solder the rest outputs of the loop according to the image and pinout of the JTAG adapter. TDO (output 13), TDI (output 5), TCK (output 9), nTRST (output 3).

Run the J-link commander. Enter commands without brackets. Approve the entry by pressing “Enter”.

Type in “power on”. Quickly type in “h” command. If you’ve done everything correctly you should see occupied processor data in the commander window.

Then type in “be”.

Download boot.bin loader and save it in the root directory of disc c:

Type in ”loadbin c:boot.bin, 0x40700000”.

Wait a moment for your file to download. If everything went successfully you’ll be notified by “O.K.” in command line.

Type in “setpc 0x40700050”.

And then “g”.

After a few seconds the printer (formatter board) will run in boot mode. You know it started when you hear gurgling that occurs when new USB device is recognized by the system.

As usual, drag the original firmware into the loader usbprns2.exe. You will see running points on the screen, and then the window will close. After a little while the printer will restart. The firmware is now downgraded.

That’s it, the device now has the firmware without EDC. Now you may buy the fix firmware at your dealer’s store and simply install it in your device.

Samsung SCX-3405W Black & White Multifunction Laser Printer

A basic mono laser all-in-one can be a very helpful little bit of set in a tiny or home office, where color isn’t a requirement, but leading quality text print is. Samsung brand-new range, where the SCX-3405W is a cordless variation of the entry-level version, decreases the overall size of the equipment, while at the exact same time maintaining a good print speed and including cordless and eco facilities.

The pale grey situation is very discreet, though a little less so as soon as you’ve pulled down the front cover to make a paper feed tray, took out the instead flimsy, two-stage result support and folded up out the silvered control panel to an extra convenient angle. There’s just one paper tray, which can occupy to 150 sheets without any multipurpose feed, and published sheets feed out with a rounded aperture simply below the scanner. The scanner lid has a finger groove at its right-hand end, folds well back when open and also has extending hinges, allowing you can scan books and also publications easily.

Samsung SCX-3405W Printing & Scan Driver

The control panel includes a two-digit, seven-segment led display screen for a number of copies, as well as specialized buttons for Eco, WPS, Scan to and ID copy. The printer attaches via USB or wireless and also although it has no LCD present, pushing the WPS button on the control panel and also a similar one on your wireless router obtains you connected with a minimum of difficulty. The single-piece drum as well as a toner cartridge, rated at 1,500 pages, is sensibly easy to fit, though you do need to pull the scanner section up fairly strongly to uncouple the latch which holds it in the area and access the laser engine cover.

The eco facilities in the driver go a great deal better than several similar makers. You can select to have an eco-preview pop up for each print, providing the chance to print grey or laid out a message and also to choose the paired print. Actually, the duplex is the default print setting on this maker, which is possibly an error, offered it just has manual centers. Information of exactly how to duplex by hand pop-up also when you’re printing a single-sided document.
