No, not important, I think you are trying to get stock on both partitions? If so, flash stock from within dd-wrt, when it reboots you should then be on stock. From stock just flash the same linksys file, that will overwrite the, not in use partition, which still has ddwrt on it. Then both partitions will have stock.

As you said i downloaded the stock firmware from linksys web , but this file is *.img and not *.bin like all the others that i flashed before .

Can DDWrt GUI (lastest version) flash a *.img file o where i can find the original firmware at *.bin format ?

There is any file Converter for do It ?

Thanks

.bin, .img same thing, you can just rename it.

Yes you can rename the factory-to-ddwrt.bin to .img or not. I do that just to keep things separated for me. Either will work for install.

Well i flashed the stock firmware .img from DDWrt GUI , It says sucessfully but the router do not reboot ... The leds on power and inet stayed off , only port 1 flash and i can not Connect as before using 192.168.1.1 ... It seems a Brick

Crying or Very sad Crying or Very sad

After a moment of panic , i try to use 30/30/30 (but i think i do not get It right) ... And do not work ...
After i pressed and hold (more of 30 secs) the red button RESET and switch off/on twice ....

Power , net and port1 lights flash again , and i can comunícate with router ...

But DDWrt remains there , and now i do not know if It os on both partitions (i prefer that yes) ...

Ubootenv get boot_part now not answer so i am afraid to try to change the boot partition

I think better solution is flashing another time DDWrt for have It on both partitions before try to revert to stock linksys

Any idea , please .

Thanks

As has been stated many times, DO NOT DO A 30/30/30 reset. Good way to brick your router. That is for older routers, just reset from within the UI or reset button on back.

I am thinking flashing again latest version of DDWrt webflash.bin file from ddwrt GUI , in order to ensure have it on both partitions ... And after try with Kongs file to revert one partition to linksys stock firmware ... But i not sure because i do not know what can happen if the another partition is damaged since i try to flash it with linksys .img

Flash the latest brainslayer twice, then flash the linksys firmware. Once in the linksys firmware, flash it again with the linksys firmware.

I had ddwrt on partition 1 and did not start the router if I tried it from partition 2.

I have managed to install ddwrt on partition 2 again and using ubootenv commands to boot from both partitions to verify that it was fine.

Then I tried to flash the KONGs file WRT1900ACS_ddwrt_to_factory.img.bin and after 15 minutes it showed me the error "Upgrade failed".

I have put the ddwrt r33257 on both partitions and this time I have tested with the official firmware (FW_WRT1900ACSV2_2.0.1.186461_prod.img) to which I have added the extension .bin -> FW_WRT1900ACSV2_2.0.1.186461_prod.img.bin

In only 25 seconds it has indicated a successful update but the led power has started to blink intermittently and finally it has been turned off, just like the internet led.
After this the router will not boot if I do not change the boot partition with the red reset button

I do not know what else to do, I can flash all the times I want the ddwrt r33257 without problems, but as soon as I try to flash a firmware back to the original, I always get errors.

1.- Can you recommend some other previous version more stable ddwrt for the task of returning to stock?

2.- Someone knows where to get an older version of the official linksys firmware (2.0.1.177097) for testing with it, which is what my router brings when I open it.

3.- There is a newer KONG file to try ? ( I used one of Januay 2016 , related in this post bi Vit5421 (http://source.wifihell.com/3-DD-WRT-KONG/K3-AC-MVEBU/LinksysFW/)

I hope you can help me, thank you

bump?

There doesn't seem to be a way to go back to stock, flashing the linksys firmware from DD-WRT temporarily makes it stop working until you reboot it a few times.

Can't find a dd-wrt-to-stock.bin anywhere for this model.

Do you have a recent build on it? Brainslayer supposedly has recently made it so that you can revert to stock by flashing the linksys firmware from the GUI.
