I have a display from a disassembled led-monitor (Wortmann Terra 2446W), that I want to use for a SmartMirror-project. Unfortunately, the monitor shows a big manufacturer logo when connected to power, therefore I am checking now, wether I maybe could be able to replace that logo or not.
The monitor firmware is possibly located on the only non-volatile memory chip I could find on the controller-board, a MX25L4006E (4MBit SI NOR-Flash). Since this chip is programmable via flashrom-utility (and listed as fully supported) and I have a flashrom-compatible programmer based on a FTDI2232H, I think I should be able to read the firmware from the flash / write a modified version back.
Has anybody ever replaced such an embedded logo, and maybe has got some hints on how to possibly identify/reverse-engineer the address-ranges and format of the integrated boot-logo ? Will eventually binwalk be able to directly identify it, e.g. in the same way that for example testdisk & photorec identify filetypes based on raw data bytes (fileheaders, block-formats e.g.) I will update this question as soon as I successfully obtained the binary firmware file... Thanks in advance for any help, Oliver
