frollic · February 11, 2023, 7:21pm

there are two 4As, since you mention warnings, I guess you've got the 2nd one ?

hecatae · February 11, 2023, 7:23pm

It'll work on fedora silverblue, which mi 4a?

openrouterman · February 12, 2023, 3:40am

gigabit one as guides are old so i dont know if they will work or not.

frollic · February 12, 2023, 6:13am

They're current, but you need to find out if the warnings apply to your device.

openrouterman · February 12, 2023, 8:00am

how do i know that here is the device i am buyung kindly let me know else i will cancel https://www.flipkart.com/mi-4a-wireless-mu-mimo-gigabit-1200-mbps-router/p/itm41c4a5dce74a0?pid=RTRG6FYTTBE3MVRK&lid=LSTRTRG6FYTTBE3MVRKQMBWLJ&marketplace=FLIPKART

I don't own the device, by the info provided here at the forum, they can't be told apart only by looking at the box.

openrouterman · February 12, 2023, 4:31pm

should i buy this or go with tp link c6
i still have option to cancel if i cant install openwrt i will not buy that device.

There's now also two versions of the 4A Gigabit. I would not recommend any Xiaomi for beginners as installation is complicated, and if ever necessary, recovery from a bricked state is even more complicated.

openrouterman · February 13, 2023, 4:06am

complicated is okey but i should be able to do that. this is necessary

openrouterman · February 13, 2023, 6:35am

Please kindly look into it.
If i can flash that delivery will happen on 16th so i have time please give me reply.

frollic · February 13, 2023, 6:41am

why ?
you already got your answer, if it's v2, it can't be flashed.
how would we know which version you're getting ?

openrouterman · February 13, 2023, 11:52am

Will it solve the flashing issues

ramips: mt7621: add support for Xiaomi Mi Router 4A Gigabit v2

Device is the same as Xiaomi Mi Router 4A Gigabit, except of: - 5G WiFi is MT76…63 - addresses of leds, wifi and eth ports are slightly changed - at the end of the flash, another `Config` partition was added, I'm not sure if we should preserve it, but I did it - patch `ramips: mt7621-dts: mux phy0/4 to gmac1` does not seem to work for this device. with him on the `wan` port there is only Tx traffic, but no Rx. so I didn't add it ``` Specs: SoC: MT7621 CPU: 2 x 880 MHz ROM: 16 MB RAM: 128 MB WLAN: MT7603, MT7663 MAC addresses: WAN **** factory 0xe006 (label) LAN *:f7 factory 0xe000 2.4 GHz *:f8 factory 0x0000+0x4 (mtd-eeprom+0x4) 5 GHz *:f9 factory 0x8000+0x4 (mtd-eeprom+0x4) Installation: Factory firmware is based on a custom OpenWrt 17.x. Installation is the same as for Xiaomi Mi Router 4A Gigabit. Probably the easiest way to install is to use the script from this repository: acecilia/OpenWRTInvasion#155 In a more advanced case, you can do everything yourself: - gain access to the device through one of the exploits described in the link above - upload sysupgrade image to /tmp - overwrite stock firmware: # mtd -e OS1 -r write /tmp/sysupgrade.bin OS1 Recovery: Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit. Possible options can be found here: https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition One of the ways is to use another router with OpenWrt: - connect both routers by their LAN ports - download stock firmware from [1] - place it inside /tmp/test.bin on the main router - configure PXE/TFTP on the main router - power off 4Av2, hold Reset button, power on - as soon as image download via TFTP starts, Reset can be released - blinking blue wan LED will indicate the end of the flashing process, now router can be rebooted [1] http://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/r4av2/miwifi_r4av2_firmware_release_2.30.28.bin ``` in this branch, I split `mt7621_xiaomi_mi-router-4a-3g-v2.dtsi` into two files: `mt7621_xiaomi_mi-router-4a-common.dtsi` (with common nodes for all `4a*` devices) and original `mt7621_xiaomi_mi-router-4a-3g-v2.dtsi` (with only `4a-v1` and `3g-v2` specific nodes). it was possible to use the original file, but then the configuration for `4a-v2` would use hacks, including deleting nodes, so why I added this division.

Script appears to work, but ftp/ssh/telnet can not connect. However it gets sto…k automatically. This is Ubuntu 20.04.3 completely stock. I also tried with option 2 to download needed files from remote github repository, no difference. *Please note the Docker would not build correctly with either docker or sudo docker, so I git cloned OpenWRTInvasion and put my OpenWRT firmware in there. ``` $ python3 remote_command_execution_vulnerability.py Router IP address [press enter for using the default 'miwifi.com']: 192.168.31.1 Enter router admin password: OpenWRTInvasion There two options to provide the files needed for invasion: 1. Use a local TCP file server runing on random port to provide files in local directory `script_tools`. 2. Download needed files from remote github repository. (choose this option only if github is accessable inside router device.) Which option do you prefer? (default: 1)1 **************** router_ip_address: 192.168.31.1 stok: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx file provider: local file server **************** start uploading config file... start exec command... local file server is runing on 0.0.0.0:49557. root='script_tools' done! Now you can connect to the router using several options: (user: root, password: root) * telnet 192.168.31.1 * ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c 3des-cbc -o UserKnownHostsFile=/dev/null root@192.168.31.1 * ftp: using a program like cyberduck ``` Then I try `telnet 192.168.31.1` But I get `telnet: connect to address 192.168.31.1: Connection refused` same with ssh and ftp. I assume this person had success with this version 2.30.20, but their advice isn't clear. https://github.com/acecilia/OpenWRTInvasion/issues/135#issuecomment-1186216223

frollic · February 13, 2023, 12:01pm

it should, files are in https://downloads.openwrt.org/snapshots/targets/ramips/mt7621/

that's not related to openwrt, it's an external utility, but is (probably) needed to install openwrt.

openrouterman · February 13, 2023, 12:03pm

All are needed else firmware can't be installed.

frollic · February 13, 2023, 12:35pm

openwrt commit says it works using https://github.com/acecilia/OpenWRTInvasion/pull/155, it links to https://github.com/MrTaiKe/Action_OpenWrt_Xiaomi_R4AGv2

you've got some reading to do.

openrouterman · February 13, 2023, 12:41pm

if this error still true EN25QX128A

now i will ask them if they could give me nfo about the device V2 of the Router with Firmware 2.30.20
if yes i will cancel or i will take it.thanks.

openrouterman · February 14, 2023, 8:36am

How do i know my device is v1 or v2...? @frollic

frollic · February 14, 2023, 8:48am

once you got it ?
it's described on the device wiki page.

before you buy it?
there's probably no way to tell, except perhaps on the EAN code on the box.
