So me no help with troubles about the "garland"?
or just me such a feature? : Hysterics:



Rep: (359)
* perun666,
Try resetting 30/30/30
  1. When switched on for 30 seconds, press reset
  2. Turn off the power for 30 seconds without releasing the reset
  3. Turning on the power while holding the reset, wait for 30 seconds and release.
if not help, then unsolder UART and fight

I read your posts above.
Alternatively try to find a full dump stick and pour it, if not help think through the UART will not be able to recover, probably loader was covered, or rather has been overwritten or corrupted firmware. JTAG is likely to help.

ps and then there was this effect?
z.z.y loader intact?

Rep: (23)
Good evening, I ask the router to the latest version 4 OpenWrt as a result of the network always appears as 802.11g instead of 802.11n as the drain and not working channel selection, tied for 40 MHz, and it is still running on 20 MHz, and the range of channels trimmed with 1-11, and had a 1-13 or even 14, if you select the country of Japan. Help to solve these problems.

Elementary, a procedure similar to the transition to dd-wrt

And what is better on a subject - dd-wrt or Barrier Breaker?
Someone likened? Now freewheeling dd, look.
Thanks in advance.

Rep: (1966)
The question is, if the router is to alter with the tablet on the dd-wrt, after flashing the wi-fi session by default it is opened, it will be possible to connect it to set up Webflash image?



Rep: (27)
* ctich
if I have correctly understood the essence of your question, it is not - can not be. But it is not necessary.
Why install more Webflash image? Do you need a factory-to-ddwrt.bin (if you have the original firmware on the router).
This file (Webflash image) sewn ifalready worth dd-wrt. Patch to a newer version, so to speak.

But the new version is already abovea linkgiven. Download it from there.
One caveat - you change it, according to the wafer on my vebmordu not empty, it had a wire connected to the wan-port, and configure.
