please help me ....

psherman · April 17, 2023, 8:16pm

It looks like you followed some other process to install OpenWrt.... you should be following the guide on the page you linked.

The recovery process that you'll most likely want to use is provided in the tftp section of that same page.

RomineK · April 18, 2023, 7:41am

I do exacly what write in https://openwrt.org/toh/xiaomi/ax3600#install_the_firmware

I miss unlock SSH because i have unlocked before (with that https://docs.google.com/document/u/0/d/14wylcOZzRMbXyP0_6ABJ8cocRNGhkLiGJprVpvioy44/mobilebasic - i use that software near 4months

Propobly its problem because i copy to putty that command:

ubiformat /dev/mtd13 -y -f /tmp/openwrt-ipq807x-generic-xiaomi_ax3600-initramfs-factory.ubi -s 2048 -O 2048 && nvram set flag_boot_rootfs=1 && nvram set flag_last_success=1 && nvram commit

and that should be 4 command ...
but its strange because i make after reboot sysupgrade and done correct

TFTP i try but cant copy file to router .... when I add it manually (by scp)... to the /tmp/tftp directory and hit the reset button (when led orange light blink) - it doesn't restore the firmware

i try do this today Xiaomi AX3600 install guide :
first fw_printenv to check - all looks goods but i cant open web site (login page)

root@OpenWrt:~# ubiformat /dev/mtd12 -y -f /tmp/xiaomi1.0.67.ubi
**ubiformat: error!: please, first detach mtd12 (/dev/mtd12) from ubi0**

and i want ubidetach and have:

root@OpenWrt:~# ubidetach -f -p /dev/mtd12
ubidetach: unrecognized option: f
Use -h for help
root@OpenWrt:~# ubidetach -F -p /dev/mtd12
ubidetach: unrecognized option: F
Use -h for help
root@OpenWrt:~# ubidetach -F -p /dev/mtd12

finaly its busy ... how to release the device?

root@OpenWrt:~# ubidetach -p /dev/mtd12
ubidetach: error!: cannot detach "/dev/mtd12"
           error 16 (Resource busy)

i can give access to that router (via other pc) - can someone help to solve problem ?

RomineK · April 18, 2023, 8:48am

and one more , in fw_printer write i have 192.168.31.1/24 addresses but i get from dhcp 192.168.1.1 and after try to enter www / login page i have ERR_CONNECTION_REFUSED

i add to network 3addresses (routing)
192.168.0.1/24 (current internet) , 192.168.1.1/24 (router ax3600 dhcp) and 192.168.31.1/24 (fw settings)

rossini · April 18, 2023, 10:12am

please before you try to install OpenWrt revert to the stock firmware via tftp.
If you installed some other firmware before it could be problematic and hard to debug what went wrong.

RomineK · April 18, 2023, 11:21am

when i use TFTP and configure pc and application like here Xiaomi ax3600 bricked - #112 by sqrwv

after make reset ... led blink orange , later it lights steadily orange and then lights up white

applicaton TFTP see nothing in TFTP Server and in DHCP Server i see 192.168.31.2 ....

Firewall in windows is off

sqrwv · April 18, 2023, 12:12pm

Before you run tftpd64, make sure there is only 1 ethernet cable connecting the computer eth port to the router and the router is powered off. Other ethernet cables must not be connected.

This way, when you power on the router (while pressing reset button), you make sure the IP 192.168.31.2 from tft64 dhcp server will be given to the router and not to some other device in the LAN.

In my case, I read I connected the computer ethernet port to the ax3600 LAN1 port. Try that way.

RomineK · April 18, 2023, 12:43pm

Thanks for help ... work ... I did it wrong because I held the reset button on the device when it was turned on ... and it would have to be on the device when it was turned off ... I uploaded the original soft ... miwifi_r3600_firmware_5da25_1.0.17.bin

so to make openwrt now, all you need to do is unlock SSH access and start installation?

sqrwv · April 18, 2023, 12:48pm

Please follow the wiki instructions:
https://openwrt.org/toh/xiaomi/ax3600#installation

RomineK · April 18, 2023, 1:21pm

I do this now and have the same problem like before

I install Chinese OEM firmware version 1.0.17, available (http://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/r3600/miwifi_r3600_firmware_5da25_1.0.17.bin)
i active ssh with that option https://openwrt.org/toh/xiaomi/ax3600#tab__javascript_method
Later step by step i do this: https://openwrt.org/toh/xiaomi/ax3600#install_the_firmware
In last steps mean sysupgrade i get:

on the router, after the above steps, the SYSTEM diode lights steadily in white, the INTERNET diode flashes white ... dont have internet

the computer will receive addresses from the network 192.168.1.1/24, the router has the address 192.168.1.1 but it cannot be accessed via web again ... ERR_CONNECTION_REFUSED if i try enter to 192.168.1.1
something wrong with that 2files here https://openwrt.org/toh/xiaomi/ax3600#firmware_download

sqrwv · April 18, 2023, 1:25pm

It's because openwrt snapshot images don't have luci gui.
You need to install luci, ssh to the router and do:

opkg update
opkg install luci

lleachii · April 18, 2023, 1:26pm

Use version 22.03.4 - not SNAPSHOT. SNAPSHOT does not have web GUI.

sqrwv · April 18, 2023, 1:43pm

This router recently made into snapshots, there's no stable releases yet.

@RomineK
Also install attended sysupgrade, from LUCI web gui or from CLI:

opkg install luci-app-attendedsysupgrade

You can use it to upgrade snapshots and it will include all packages you use including luci.

lleachii · April 18, 2023, 1:47pm

Then failure when browsing to 192.168.1.1 is expected behavior. I'm not sure why OP notes it as a symptom

OP must first have LuCI installed opkg update && opkg install luci
Use the firmware selector to include an image with LuCI

Here: https://firmware-selector.openwrt.org/?version=SNAPSHOT

sqrwv · April 18, 2023, 1:51pm

It's in my previous post, howto install luci.
We replied at the same time.

@RomineK
It's also in the ax3600 install instructions:

RomineK · April 18, 2023, 4:02pm

Ooo, I understand that you want to say that I did everything correctly, but for the GUI/www to be displayed, I need to install some lucy? it's great to be a layman and not read everything ... I restored the OEM twice and I did everything right, only the www interface was missing

u know any installataion of OpenWRT on AX3600 with LuCI include?

To install LuCi need internet on the router? is the installation already included in the snapchat version?
if I need the Internet, I need to know how to change the settings using the console so that the router has the Internet?

https://openwrt.org/docs/guide-user/luci/luci.essentials here nothing write about it then i think i need Internet in router.

sqrwv · April 18, 2023, 4:15pm

@RomineK

To solve the issue that you don't have internet after you install the snapshot if you don't configure the router, you can do this:

PS: I replied to wrong user, now can't fix it, it says I'm posting the same msg.

lleachii · April 18, 2023, 4:23pm

(It takes a few mins - but you can copy, delete, then reply correctly.)

RomineK · April 18, 2023, 7:55pm

Which of these 4 links do I need to install in the router to have LuCI? https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=ipq807x%2Fgeneric&id=xiaomi_ax3600

1 , 2 , 3 or 4 .. or several ?

I installed from the links above - it has the same name and size...
is the sysupgrade from the links above (the same name and size)

so it turns out that KERNEL? do i understand it right? and how do i install it? same as upgrading to this version of sysupgrade?

i know how install factory version and how made sysupgrade (this: https://openwrt.org/toh/xiaomi/ax3600#firmware_download)

i dont know how add LuCi if dont have Internet in router ?

or i dont know how change internet configuration without web interface to take Internet in router? edit: i write more maybe i have fiber (pppoe) Internet 1gb/s with name and password to connect (ip take dynamic)

sorry for asking but i am newbie

sqrwv · April 18, 2023, 8:32pm

Press here: https://firmware-selector.openwrt.org/?version=SNAPSHOT

Type AX3600 in model and select Xiaomi AX3600.

Open Customize installed packages and/or first boot script and add luci at the end of the Installed Packages list, separated by a space like the others. (Example: ... urngd wpad-basic-mbedtls luci)

Press Request Build.

Go to Custom Downloads and download sysupgrade, then use that file: openwrt-4cb0b7dad2f8-ipq807x-generic-xiaomi_ax3600-squashfs-sysupgrade.bin to sysupgrade.

It's the snapshot sysupgrade.bin but it will have luci added.
