Hello , As the title says, I was planning to make the move by reading the instructions from www.dmach.net/blog/2010/08/22/upgrade-your-linksys-router-literally/ However, since I would call myself a semi-noob, I had some queries, which apparently were not cleared on the metioned page. I thought of heading over to this forum to ask if any of us has done it successfully and what are if any further cautions and observations. My own queries were as follows : I have a WRT610Nv2 running Tomato Shibby 1.28.xxxx at the moment. I wanted to upgrade it to E3000 for extra NVRAM, since it is always short. I have downloaded the following files from the above-mentioned page dd-wrt.v24-14567_modified-e3000.bin cfe_e3k-GENERIC.bin Following from point no.4 (from the original blog post) I wanted to update the BIN file first. I assume the file referred in this point is the newly downloaded generic BIN file, and not the actual original BIN file which is backed up from the router in the current state. Correct ? I did note down the MAC,Serial No and Wireless Key from the router sticker. I am using Hex Editor Neo Free Version, I open the file in it and browse to 0x1E00 as follows : It shown the following values 1. But when i start entering the full value of the my router's MAC address, the last character jumps into the next line...is it ok and safe ? 2. Similary for any other value if the character jumps into the next line, then should it be left as is and will behave normally.? 3. Lastly there are 3 more MAC addresses assigned in my router as shown in the current firmware MAC details. Can you please tell do I need to copy these into the generic BIN file and if needed then where do I place them, the items 1,2,3 as in the attached screenshot ? Thanks for the guidance from the experienced members here so I can proceed.
