I Have TP-Link TL-MR6400 V5.2,and I install Openwrt,But 4G modem Is not working,i decide restore to Original Software,so i followed all guide about "TP-Link Openwrt restore original sorftware".
Everything seems fine,but i get much error.
i download TP-Link TL-MR6400 V5.2 Original Software(V5.20_210115) it .bin size is 62.5 MB,i use tftpd64,set complete parameter(ip,mask and bin name(tp_recovery.bin))
it show a error message Timeout waiting for Ack block,Remove power and plug it back in it just repeatedly blinks the power LED and all LEDs,so i change another way.
i use WinSCP put the Original Software bin in the router,it show a error message"scp: /tmp/original.bin: No space left on device,i check dir,file is upload,but size is only 28 MB,after i use dd if=original.bin of=tp_recover.bin skip=1 bs=512 count=16000 at Putty,it show a error message
dd: error writing 'tp_recover.bin': No space left on device
1+0 records in
0+0 records out
so...Until now, I have been using the mobile base station of my mobile phone to share to MR6400 to bridge the Internet, but it is very stuck, I don't want to continue like this, please help me.
Modem would probably not work in openwrt out of the box, need to set it up.
Make sure the firewall's down on the host running the TFT server, you could
also try putting a switch between the computer and the router.
The dd activity should probably be run on some other host, than the router,
but there's no dd info on the device page.
But since your device only have 64MB RAM, and /tmp will be 50% out of it,
there's no way you can fit a 60+MB file there.
Been there, was almost hit by a rock coming down the hill, while driving back to Taipei, on the east coast
Pretty sure I managed to get a speeding ticket too
