Stuck in recovery mode

[irishguy90]

I recently updated the firmware on the rt320 via the gui and noticed the WiFi could work so I held in the reset button to see if that would resolve it but it's didn't. Instead it booted to recovery mode and no matter what firmware I flash with it just goes back to recovery

I also have the same issue. WiFi was non-functional after upgrade, so I attempted to rollback via an older image, and now I am in recovery mode with flashing having no effect.

You have most likely flashed a wrong image. Please see #104

Iv read the guide tried flashing most the firmwares and used some command but they don't work

This what comes up with some command iv tried

root@OpenWrt:# ubinfo -a
UBI version: 1
Count of UBI devices: 0
UBI control device major/minor: 10:63
root@OpenWrt:# ubinfo -d 0 -n 5 -a
ubinfo: error!: cannot get information about UBI volume 5 on ubi0
error 2 (No such file or directory)
root@OpenWrt:~# hexdump -C /dev/ubi0_4 | head -n 34
hexdump: /dev/ubi0_4: No such file or directory

the files im trying are
ede-mediatek-mt7622-MTK-AX3200-MT7531-squashfs-sysupgrade
openwrt-22.03.1-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery-installer

root@OpenWrt:~# hexdump -C /dev/ubi0_2 | head -n 34
hexdump: /dev/ubi0_2: No such file or directory

iv even tried FW_RT3200_1.0.01.101415_prod.img and still stuck in recovery
iv also tried
Switch device power off.
3x Switch device power on for 2 seconds, then off again.
Switch device power on, the device should now boot to the alternative partition.
and also powered off for 10 seconds after using openwrt-22.03.1-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery-installer.itb still stuck in recovery. im not sure now what else as iv been trying for few days now and still stuck in recovery

rm /sys/fs/pstore/* does nothing

[dangowrt]

You need to do things in the right order.
So:
Step 1: rm /sys/fs/pstore/*
Step 2: sysupgrade https://downloads.openwrt.org/releases/22.03.3/targets/mediatek/mt7622/openwrt-22.03.3-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb

Do not reboot after rm /sys/fs/pstore/*, directly proceed to sysupgrade the correct file.

rm: can't remove '/sys/fs/pstore/*': No such file or directory
tried that link and again straight back to recovary

[damo901]

this what comes up with these commands
ls /sys/fs/pstore (nothing shows)
cd /sys/fs/pstore
vim dmesg-ramoops-0

i think its fixed. i tried these again

Using PSTORE/ramoops

While running the production firmware enter this command in the shell

echo c > /proc/sysrq-trigger

Once the router has rebooted into recovery mode, clear PSTORE to make it reboot into production mode again:

rm /sys/fs/pstore/*

Just wanted to say i too had this problem - flashed two units with the files provided in this repo and was working on configuring one with VLANs - after a save and apply - ended up in this reboot loop for no apparent reason.

I followed these direction above and that appears to have resolved the issue

While running the production firmware enter this command in the shell

echo c > /proc/sysrq-trigger

Once the router has rebooted into recovery mode, clear PSTORE to make it reboot into production mode again:

rm /sys/fs/pstore/*

I recently had this same issue going from 22.03.5 to 22.03.7 and spent a whole night trying to figure out how to fix it. This should really be documented.
I followed these directions to fix:

While running the production firmware enter this command in the shell:
echo c > /proc/sysrq-trigger
Once the router has rebooted into recovery mode, clear PSTORE and downgrade:

rm /sys/fs/pstore/*
sysupgrade https://downloads.openwrt.org/releases/22.03.3/targets/mediatek/mt7622/openwrt-22.03.3-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb
