The factory images are used to convert from vendor's firmware to OpenWrt.
After that, when you already run OpenWrt, you should use the sysupgrade images.
Ok, however at this moment I only can access to the page for firmware upgrade. Even if I upload a sysupgrade image, I can't recover the device. Only what I get is the same page that I show in the picture.
Check the currently installed vendor firmware. If it's 3.5.x or newer, you need the -factory_35.bin image. Otherwise, you need -factory_30.bin
Now this page doesn't look to me like Luci, so most likely it is from the factory.
Follow these instructions:
Note: Reset router to factory defaults if it has been previously configured and you don't have the admin password. To reset, power the device and wait for it to fully boot. Then press the reset button for 11 seconds until the sys led starts flashing. Release the button and wait for the device to reboot.
Then try to flash the OEM firmware, since the sysupgrade won't work.
It's not Luci, but it's not the original as well. I installed the -factory_35.bin as they say.
Now, I only have that page. The page only can upload the sysupgrade file, any other fail and says that is invalid and don't upload.
Not OEM firmware, not anything else. Just accept and perform upload and write till 100% for sysupgrade files from openwrt. After that it's not possible to have luci or enter failsafe mode. By access the page again, we get the same upload page.
same issue i'm encountering, if any of you has a solution to access the device and make it work to be able to configure it please do let me know, detailed how to guide will be appreciated too.
I'm going to try to connect via serial and try to recover from there. Maybe the "factory_35.bin" have some issue or I used it in a wrong way. "factory_30.bin" worked but I was unable to activate DHCP. So I decide to flash it with factory_40.bin and I can't access anymore. Just that page that permite upgrade the system and accept only sysupgrade files. I already try to access via FTP, TFTP, SSH, trying to enter in fail-safe mode.... nothing works.
Serial connection is the next step. I already purchase a serial 3V3 adapter, I need to disassemble and put the wires in place. Hopefully will work....
You were not supposed to use them both. You use only one according to the version of the vendor firmware. Then you would upgrade to OpenWrt, but most likely the second factory.bin flashing messed it up.
