Hello ddwrt Gurus,
I am just trying to make use of my old router(Generic CPE) as a repeater but it has a custom firmware which doesn't let me configure the way i want it to. thought to leverage DDWRT for this project. PS: I do have root access to it
Would you be guys kind enough in helping me find the appropriate firmware i can use it with, that would be very helpful.

Is there a FCC ID on the bottom label?
If so, what's that number?
The specs of this router seem very similar to a TP-Link WR841ND v7 vintage router... or more closer to a WR2543ND: Your hardware looks like a private label of slightly cheaper version of the WR2543ND. The problem is the header file won't likely match to your private label router.
AR7240 CPU and ATH9380 wifi...N300 vintage router 10+yrs old with an anemic 400mhz CPU.
The combo of CPU and Wifi don't match anything I've seen under supported hardware before.
This thing will be a dog for sure...I would say invest $25-$35 in a used Archer A7v5.
Otherwise, OpenWRT with a generic build for that combo of hardware you have is the only other option AFAICT.
DD-wrt support will not be coming to your router any time soon.
What happens when you run wireshark; can you see if it looks for TFTP on boot with an ARP request?
If so, that will better show this is private label tp-link shit. _________________ FORUM RULES
@msoengineer: Thank you so much for your efforts, Much appreciated.
This was sitting idle at my place, thought to make use of it rather then spending on buying another one. Since I am free.. I'll be really happy to see this shit working you know the kind of happiness we get when we loose weight and our old jean fits in... you know, what i mean!
Any other thoughts on the router? would TP-Link 740 N a closest match for this ?
Then you need to find something in the original firmware which can be "mis-used" to transfer the cfe.bin to your local computer. scp, tftp, ftp
If you're saavy, you can also "mis-use" the webserver of the original firmware to download it, by changing the default directory to /tmp there is no singular way to save & transfer the CFE.bin which works for all routers/devices.
All of this is beyond my "playing" around experience and I have not yet delved into this level of "hacking" yet... no time or real need... My time is too valuable to spend it on this right now... Maybe one day I will make the time for it.
Otherwise, feel free to contribute and make a how-to guide to help me and others. _________________ FORUM RULES
Good stuff here! Admittedly, matching the SoC would be easiest/best if there were a close enough match, but it just seems to me that the focus should be on matching the CPU and wireless families (as well as obviously minimum flash size for the build). Clock speed is a red herring, at least from slower build to faster hardware.
Question: Would the System on a Chip (SoC) itself be irrelevant as long as its internal components (mainly cpu family and wireless family, but please correct me if I'm wrong) were matched (as well as obviously minimum flash size for the build, and possibly minimum RAM size for the OS), even if only as discrete components in a supported device build? Or, is there something special about OS parameters for a SoC?
I'd thought SoC was mainly packaging (with some obvious size/cost benefits) along the lines of a re-branded device where the mere movement of discrete comonents onto a SoC should make little difference to operation, except possibly allowing for potentially faster clock speeds due to shorter interconnections, although temperatures might be more critical depending on SoC heat-sink/fan. But clock speed can be tweaked anyway such as we've done from the old WRT's to more recent R7000's (which I've overclocked 20-60%, and ran one at +20% for over a year up-time with no related issues). Besides, a slower-clocked build (e.g., 350 MHz) would likely run just fine out-of-the-box on slightly faster hardware (e.g., 400 MHz).

The key to making it work is getting the CFE.bin and then looking at the details contained in there to be able to tweak it to make dd-wrt work...
AFAIK, BS is the only one left that can do that work. Eko, Tornado, Sash, Markus are all doing other things and can't help.
The issue is that all this is a hazing ritual to ferret out the real developers from the everyday casual hack like me...
Again, I need to focus my time on keeping my day job and then family.... this is just a dumb router that helps me get online....I am not making a career out of it, nor any side-cash...purely volunteering too much time already...
I am moving on now. Best of luck and maybe another lurking guru will chime in with real details to help put together a how-to guide.... _________________ FORUM RULES
Thanks and understood @msoengineer! I'd also have to agree with your advice to @mohit0121 about moving on to fresher hardware. Even if the build I'd mentioned earlier had both flashed and booted, I just realized that it doesn't support repeater mode from the wireless mode pull-down menu (the intended application IIRC). Not much of a reward for all the effort involved, unless solely an academic exercise (which is ok too). Cheers!
after lot of back and forth emails with brain slayer, I got to know the generic uimage that should be compatible with my router is glinet ar 150 or 8 devices. I have downloaded the firmware from the betas ddwrt section but the irony is my router doesnt let me even upgrade the router from the OEM GUI. when i tried to connect via telnet then i got to know that it only updates via the script and on the given instructions hardcoded in the router. I am hereby attaching those scripts, if any of the guru here can suggest something?
here is the script:
