Samsung has once again strengthened encryption firmware, and released a new version of the form VX.XX.02.XX. Last week, I already got a new phone from a supplier with such filth.
Now encrypted not only the kernel, but the loader and a dump of the file is no longer possible to do. In addition, added a checksum, however, the standard algorithm – CRC32. Another joy debug mode is cut on the eggs. And most importantly, added validation of digital signatures ECDSA .

ECDSA
Based on the foregoing, we conclude: downgrade to version V3.00.01.19 – the only working option. Pick up the key signature is unrealistic, that is on firmware version V3.00.02.xx will never happen! (If the key is not accidentally flow away).
We need:
Programmer for flashing SPI FLASH (more about it at the end of the article).
Soldering station with a hairdryer.
Tweezers.
HEX-editor.
The original firmware, which will reduce the.
Start to downgrade firmware version of Samsung printer:
1. Put the machine on its side, up the side, which is inserted USB-cable:

11. Read and just in case, save the dump:

12. Now prepare dump 19 version. To do this, open the full firmware file (take here: http://resetprinters.net/contact-us, and not only in Samsungs site, this is important!) and delete the title, ie, the first 120 bytes (0 × 78 in HEX-format):

13. Save the file and open it with the programmer, write the dump to a USB flash drive:

14. Soldered to a USB flash drive, return the card into place:

15. Print:

That’s it, nothing complicated, if there is a tool of work for 10-15 minutes.
Now the programmer. Just say scheme for PonyProg not work! Need support SPI FLASH, and he can only SPI EEPROM.
I have a MiniPro via USB, great speed, a good set of adapters and all this for less than 100 USD! The only negative – Chinese software, but this is easily corrected by installing softiny WizardProg (same programmer under the Russian brand) http://www.wizardprog.com/ download.htm
For those who want to make their own programmer propose several schemes: http://freesofts.info/wp-content/uploads/SPI_PROG.rar On some files can swear antivirus software, but it is false positives. I myself have not tested these schemes, as there MiniPro.
This way you can humiliate all devices are installed stick series 25Q:
