I have tried to revert to stock firmware on my Linksys WRT1200AC. I get the following error
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
I have reset the router and pulled the power and network cables for 3 min. ( then plug back in) then go to the logon page enable the wifi with wpa2. after I enable the wifi I save and reboot. I have no connection to the web. I tried to ping 220.127.116.11 and drops all packets. Any advice and help is greatly appreciated,
Here are instructions on how to change the boot partition. I have used this successfully to boot back into the stock WRT1200AC firmware. This allowed me to then upgrade the other partition again to a different version.
To do what? All three things I described are on the wiki page I linked. But for scp I prefer this over putty, ymmv. In my own build I use this to control what partition I am on, or which I want to flash. Some like to stay with OEM on one of the partitions, but it is not necessary.
sorry for the delay.
I have tried to scp firmware to /tmp and i get a no space error like i did on the root directory.
I have tried the reset button for 15 seconds and still am unable to flash any firmware except lede.bin only.
I have no internet connectivity on the wired side. I have enabled the wifi and no internet on the wireless.
Your router should be equipped with dual partitions, so when something goes bad, it boots on the second one. Each time you flash your router from one partition, it write on the other then trigger a reboot to that other partition. This allows you to roll-back if anything goes wrong.
If you are actually on LEDE, then it is possible to force a switch to the other boot partition that should contain your stock firmware using the "cut power trick", mentioned in anomeome's post.
I'm in a similar situation (though on a 1900ACSv2):
I was able to flash a LEDE image onto one of the partitions, but I must have made some kind of configuration error because the partition became unbootable/not accessible over the network. I used the triple reset to switch over to the backup partition containing the manufacturer firmware (which works normally). I've read that there's a procedure which allows you to overwrite an unbootable alternative partition on a Linksys device using the bootable one, but the associated instructions weren't specific beyond needing to use the 'factory' image of LEDE.
Could someone in the know say if this is possible?
Both the OEM manufacturer firmware and LEDE/Openwrt always flash the other partition and then switch boot to that partition, so that the current one remains intact and serves as a fallback. That is the standard ops.
As you current run original Linksys firmware, if you now flash LEDE, it will automatically get installed to the alternative partition. (After the flash, your current partition will be the "alternative")
