First, My 3020 run with http://downloads.openwrt.org/chaos_calm … actory.bin
I want to install packages about usb device, but the memory space is insufficiant.
And I found this topic https://forum.openwrt.org/viewtopic.php … 9&p=22 Wingman2k posted the firmwares that usb devices kernels are included.
So, I try to flash firmware but I forget to select the factory firmware, I flash with Sysupgrade instead.
Device is flashing more than 10 minites and I realize that I pick the wrong one, So I immidiately unplug the device and reboot it.
Now, My 3020 can't be accessed by luci but telnet can do.
I try to do follow this article
"Downgrade Attitute Adjustment from Trunk
Downgraded wrong image ( jff2 instead of squashfs ) cause cant get ip or connect to luci. Failsafe mode still working but firstboot command wont work because it is already on working. You can upload correct firmware and write it with mtd command but failsafe mode can't connect internet. You need to local tftp server to get firmware.
Set your pc ip 192.168.1.10/24 and gateway 192.168.1.1. Download mongoose http server and correct firmware same folder and start mongoose. It will host all files in his path ( if you start it from downloads folder it will host all files in downloads folder )
now we can get firmware via failsafe telnet:
wget http://192.168.1.10:8080/openwrt-ar71xx … actory.bin
mtd -r write /tmp/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin firmware
Writing from /tmp/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin to firmware ...
Rebooting ...
/bin/sh: /sbin/reboot: Input/output error
DONT DO ANYTHING. Just wait and router reboot itself. wait few minutes and you will able to reach Luci via 192.168.1.1."
But when i use the command
wget http://192.168.1.10:8080/openwrt-15.05- … actory.bin
It run about 10% and stop seems like there is no more space available.
I try to connect Mr3020 to internet but it cannot.
Please help
Ps. Sorry for bad english
