G'Day, I have a stand-alone Liteon 5115 DVD recorder that I purchased to transfer my VHS tape collection to DVD before VHS hardware becomes obsolete. Unfortunately, many tapes cannot be transferred as the recorder displays "Protected Content" (i.e. Macrovision) and recording will not proceed. Legally, under our fair-use law, we are allowed to make a personal copy.
Therefore, I did a hex-dump of the firmware (a copy of the firmware is available at:
At 0x2DB9F1 a reference to Mediatek (Manufacturer of DVD Recorder chipsets who have also signed an agreement with ARM).
At 0x361DC a reference to ARM
At 0x2D78DD the following hex string: 55 53 00 00 00 00 00 01 00 00 00
00 (This is the same string that a Liteon 5005 recorder uses for its Region Code and Copy Protection switches which can be modified to 55 53 00 00 00 00 00 00 00 00 00 01 to make that recorder Region Free and Copy Protection disabled.Please advise, in layman terms if possible, the steps and tools required to fully reverse engineer (disassemble/decompile/debug) this firmware to discover checksums, etc. TIA!
