Help me debrick my r3p pro

Installing and Using OpenWrt
1

Hi, i did something stupid last night, i upgrade the r3p pro in luci, after that the router went into a bootloop.

tried to revert it in u boot, but failed.

i still have acces to the router by TTL link and ssh, but those command i follow in the site always gave me error, like" /bin/ash: fw_setenv: not found"

i also tried to recover to Xiaomi stock, but after the led start flashing and releasing the reset few second after it start to blink red fast..

i can do opkg update, but when i try to install luci i get this

root@OpenWrt:/# opkg install luci
Installing luci (git-20.276.62798-011b4db) to root...
Collected errors:
 * verify_pkg_installable: Only have 0kb available on filesystem /overlay, pkg luci needs 1
 * opkg_install_cmd: Cannot install package luci.

What is the output of the

mount

command?

Not sure how r3p pro’s firmware works, but it looks like you’re out of space.
Can you do df -h first and post the output here?

this is what i get

this is what i get

Edit the file /etc/opkg.conf. If it is not there copy it from /rom/etc/opkg.conf.

Then edit the file:

dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay # remove this line
option check_signature 1

Then opkg update.

done, then??

to me, it seems like there is no sda for me to install stuff in.

this is what it come up when i try to recvoer with usb

Then you can try opkg install luci. It should be without /overlay error.
Since your root is writeable, it should install.

this is what i get.

root@OpenWrt:/etc# opkg install luci
Installing luci (git-20.276.62798-011b4db) to root...

 * verify_pkg_installable: Only have 0kb available on filesystem /, pkg luci needs 1

root@OpenWrt:/etc#

What happened to the /dev/sda? Was there a drive installed before?

11

no, i think its the usb memory stick, seems like it cannot mount it in the boot

12

Can you mount the memory stick in an ordinary computer and find /etc/fstab file.
Can you do now a cat /etc/fstab in the router's shell?

13 
# <file system> <mount point> <type> <options> <dump> <pass>

that is what inside the fstab file

14

And in the fstab on the stick?

15

there are none, only the miwifi_r3p_firmware_daddf_2.13.65.bin (developer firmware) which i try to restore the router with

16

Try

opkg install luci -d ram

.
This is just until the reboot. Do you want to install sysupgrade via web?

17

well, what i want it a new installation of openwrt, seems like mine is screw up hard time...

root@OpenWrt:/etc# opkg install luci -d ram
Installing luci (git-20.276.62798-011b4db) to ram...

 * opkg_install_cmd: Cannot install package luci.
root@OpenWrt:/etc#

this is what i get running the code you suggest

18

Then cd /tmp

and follow https://openwrt.org/docs/guide-user/installation/sysupgrade.cli

Make sure you download the correct image for your device.

19

yup, gonna try this..

do you know how to restore the rootfs? i think its there its mess up

20

That is hard to estimate, since I don't know what has been changed / destroyed.
Try the cli way of sysupgrade. That seems at the moment the cleanest way.
