To bad when I just dropped in 64MB in it, which can be desoldered again ofcourse. I got a MR11U coming in so I will continue play with that. Maybe its time to fix me a flash editor utility, they should be similar enough to facilitate for a direct copy. From what I underrstand there are 16MB eproms out there that I could use as well, problem would be to source it. In any scenario, if I can't get extroot to work properly or bigger flash I'll throw them both in the drawer. 4MB is simply too small, simple as that.
Does anyone have any idea on what flash/eprom editor utility one can use for this?
@Lennong
I am under the impression that you cannot brick WR703N if the uboot is intact. Maybe something wrong with your setup or tftp server.
Even 8MB ROM may be small for you. Wait a few weeks and my extra-root should be ready.
You are absolutley right. I did have a go again and got it back to life. I initially did follow the instructions for the TL-MR3420, which has a few differences from the ones for the TL-MR3020, which are more accuarate. I had to set environments first, device IP and server IP, even though it automatically put out that it had 192.168.1.111 and expected the image to be at 192.168.1.100. So, even though it supposed to be preconfigured I did the steps and set environment anyway (same adresses). After that it suddenly wanna talk and soon it was back alive.
Thanks for the support.
Anyhow, I did order me a USB flash programmer so I really can go havoc on the MR11U.

It seems to do the job from what I can see in terms of support and the software. I also did some research on the 8-SOPs available for this device and it seems like 200MIL is limited to 64Mbit/8MB. However, when I look at the 16-SOP diagram the inner 8 pins is unused, and the outer is eqvivalent to the 8-SOP pins, just in a different order. This means that I can drop in a hefty 256Mbit/32MB flash in there somewhere, if uboot allows the mod that is.. I saw somwhere on the forum a TL-MR3420 with a 16MB flash, and he did mod the uboot to make it accept it. I'm ging to Singapore in a couple of days and will have a couple of hours to spend on chasing some flash chips.
