You tried to keep the corresponding number pressed while boot? Or press "c" or "s" while boot (unplug router, replug it again)
Yes,tried holding number.
C or S also makes no difference, it auto jumps to load from flash.
I cant believe that it is stuck in this loop, any idea to recover?
@dgiese Still giving me the same error.
I really dont understand why is boot menu selection time of 5 secunds just skipped altough boot menu is displayed.
No buttons pressed really help.
I am out of ideas to recover
My R3 is still bricked so I have no way of testing, but I added @dissent1 uboot mod to enable preserving kernel0 for future recovery.
If someone wants to test here it is:

Can somebody who has stock firmware installed check if kmod-softdog is used in stock?
Hello,
I'd like to help getting lede on this router.
I've gotten ssh on it, it's running the stock firmware.
I will be able to check for the kmod-softdog kernel module in 16 hours. - Can I check it simply using lsmod?
I dont know since mine is currently bricked.
Hello,
there you go lsmod from mine running stock development version:
root@XiaoQiang:~# version
Uboot Version: 4.2.S.1
Linux Kernel Version: 2.6.36ralink
XiaoQiang APP Version: '2.13.75'

Thanks, all my work is suspended due to not being able to unbrick my R3
so as i was searching to try out pandorabox due to slow 2.4ghz speeds on openwrt and lede with my xiaomi mi wifi mini
i stumbled on a device firmware recently integrated named xiaomi-r3.
since i own both mini and mi3 i thought maybe some development has taken place.
"PandoraBox-ralink-mt7620-xiaomi-r3-2017-09-19-git-a820134-squashfs-sysupgrade"
any thoughts?
here are the links
https://lt.tn/FORUM/thread-252336-3-1.html
http://downloads.pandorabox.com.cn/pandorabox/17.09/targets/ralink/mt7620/
Pandora box for R3 exists for a while now.
The issue is that they are no sources and used drivers are Mediatek proprietary closed source drivers which LEDE cannot distribute.
yes im aware of that, i didnt know until now it has support of pandorabox.
so that means the r3 can run pandorabox?
how is the flashing process? can anyone shed some light since i want to avoid bricking.
i remember back when i tried pandorabox on my mini that is and switched to lede i did the upgrade through the webui for convenience and it worked.
is this reccomended?
furthermore im currently running padavan on my R3 and the partition layout therefore is different
does this mean if i wanted to try out pandorabox on the R3 i must revert to stock unlock SSH again from start and then flash it through SSH?
i have quite some experience but by no means as advanced as you guys so i could use this information to prevent bricking if anyone could be so kind
i used the recovery option on a virtual machine with prometheus followed by inserting a USB stick and holding reset.
my goal was to go back to stock and apparently i read this method worked on forums.
however now my r3 has a yellow light for a couple of seconds when booting and a red blinking led after.
it isnt recognized anymore nor does boot
............................................................
update: tried another fw version and it worked
i cant make sense out of the chinese tutorial:
pb-boot-spi-recovery-xiaomi3.bin ΣΓΣΪΠ΅ΓΧΒ·ΣΙΖχ3µΔSPIΖτ¶―,ΣΓΣΪΠήΈ΄NANDΠήΈ΄
pb-boot-nand-xiaomi-r3.bin ΣΓΣΪΠ΅ΓΧΒ·ΣΙΖχ3µΔpb-boot,nandΖτ¶―.

Π΅ΓΧΒ·ΣΙΖχ3µΔPandoraBoxΉΜΌώ,Φ§³ΦNANDΖτ¶―,ΤΪpb-boot»ΦΈ΄Δ£Κ½ΟΒΙύΌ¶,
If you stumble upon sources of Padavan for R3 or PandoraBox please contact me.
Maybe there is something usefull
i hesitate i will, especially since i dont speak chinese
does anyone know how to flash pandorabox on the r3 though?
....
what i got out of the tutorial using google translations 
In fact, really simple, router R3 brush version of the firmware and then open the SSH, use WinSCP upload PB BOOT, putty go brush PB BOOT. My router last brush the old hair firmware. Padavan Brush PB BOOT Command: mtd_write write /tmp/boot.bin Bootloader
...
in this file there is a boot file for spi and a boot file for nand and the firmware... there is not a whole lot of usable information on flashing especially after translations of google
i flashed the above rootfs0 and kernel1. however my router now constantly disconnects from the lan cable and reconnects rapid. the led is orange and flashes goes back to steady and blinking all over
uploaded through winscp on /tmp
ls /tmp
mtd write ...kernel1.bin kernel1
mtd write ...rootfs0.bin rootfs0
and the following steps and rebooted
since i didnt understand is the sysupgrade through uart? since im a bit confused..
didnt flash kernel0 as suggested as well for the recovery function
cant recover official firmware through usb anymore either

If you read through this thread you would have seen that images yet dont work for this device.
And since you didnt read latest instructions that include new image that does not require deleting kernel0 you wont be able to just recover from usb.
You need serial cable in order to load initframs kernel image and then flash stock kernel and recover from.usb
im busy trying to solder the serial on since i did a bad job the first time..
so this means this constant bootloop sort of can be fixed and u-boot is intact for me to flash through tftp or initframs as u say?
never tried it through the initframs way..
i could use some more info since relatively speaking im a noob
.. actually no i didnt , i read that info i just did the the kernel1 btw
so just got it booting through the bootloader on serial i flashed pandorabox through option 2 as the usual procedure goes for flashing. not of the chinese forum but straight from the latest pandorabox build...
it didnt work as its suposed to unfortunately. ill be giving more attempts tomorrow
