Which one? I downloaded the sysupgrade image from here ( Xiaomi Mi Router 4A Gigabit Edition (4A Gigabit / R3Gv2)). When I try to flash it I get:
Device xiaomi,mir3g-v2 not supported by this image
Supported devices: xiaomi,mir3g-v2 - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA
And I see the snapshot table at the R3G site for v2 is empty. Should I use the v1 binary?
The images were renamed some days ago, so thats why there are no working links in the wiki pages.
Use this link for the sysupgrade snapshot:
https://downloads.openwrt.org/snapshots/targets/ramips/mt7621/openwrt-ramips-mt7621-xiaomi_mi-router-3g-v2-squashfs-sysupgrade.bin
If you use the newer snapshot, you also need to use the force flag, because OpemWrt switched from swconfig to DSA.
Which one is printed on your router's sticker? Is it eth0.2?
Long story behind, seems I bricked my 3G-V2 and already ordered CH341A etc.
I will edit your edited SPI Dump to match my MAC address using HxD, before write it down to my chip later while waiting for the tools to arrive.
I also have ordered 2 Xiaomi 4A Gigabit (Chinese & Global) and will dump the SPI for both firmware too.
Yang mana ada di stiker routernya? Apakah eth0.2?
Ceritanya panjang sebenarnya, sepertinya saya batain 3G-V2 dan sudah pesan CH341A dll.
Saya mau edit SPI Dump bapak yang 'edited' agar sesuai dengan alamat MAC saya pakai software HxD, sebelum diisi ke chip saya nanti sambil menunggu alatnya tiba.
Saya juga sudah pesan 2 Xiaomi 4A Gigabit (Cina & Global) dan akan bikin Dump SPI untuk kedua firmware tersebut..
The one on the sticker label is for eth0.1
From what I have read 3GV2 and R4GE have identical hardware but different bootloader, which R4GE seems better in recovery to stock.
If I have both 3GV2 and R4GE, using CH341A dump their flash for backup safety reason.
Is it good idea to make a copy of R4GE dump file, edit the file to match 3GV2's MAC address with hex editor then write it down to the 3GV2 so it become the R4GE and have the same bootloader?
Maybe that way I can make 3GV2 much easier back to stock from OpenWRT or even bricked situation with R4GE firmware as it's now a 'R4GE'?
Some people has PM'ed me about this file for using on their Xiaomi Router 4A gigabit edition, and after flashing it with CH341A , their router is detected as R3G v2.
I reckon, you can also do the opposite. But no promises though, and if I were you, I would make backup of my router before doing anything..
Of course as I stated before about making backup.
There is a possibility I might receive faulty CH341A like you did, so it best make more than 1 file each chip then hash them right?
Is using windows okay as long as I got good CH341A?
Even if I failed to flash using R4GE dump image file, still have image of 3GV2 from you (edited MAC Address to match my sticker), many thanks for that..
Yes, my new ch341a and (also new) clip works fine under Windows.
Just want to inform you, I succesfully flash my 3GV2 with 4AGE dump image from post link above. I Edited Mac Address to match my sticker (eth0.2 = 0x5E006), default SSID to match the label too. I don't edit the serial number because there is 1 length difference between 3GV2 and 4AGE.
My device become 4AGE with factory firmware 2.28.132, upgrade it to 3.0.24_INT, and later OpenWRT 19.07.4 r11208.
I also backup my spi flash running openwrt and realized it exactly the same as file combined from OpenWrt.mtd0.bin to OpenWrt.mtd7.bin I got from luci (using hash).
@unbricker probably not important, assuming that you already have SPI Flash Programmer such as CH341A and the device is 3GV2 not 4AGE you can take it further to edit the CTEI Number, Serial Number, and SSID to match your device (printed on the box and router lable)
SN=23xxx/A9RA8xxxx offset are:
0x3013A , 0x40004
In case of @abdulaziz.amar dump file
ssid=Xiaomi_D42D_2BD2
D42D is from EC 41 18 C8 D4 2D (4 last digit of mac address/eth0.2)
and 2BD2 = FFFF - D42D (Just use hex calculator), offset are:
0x300BB , 0x300EA , 0x40055 , 0x4006D , 0x11ECF3 , 0x11ED22 , 0x11F5AB , 0x11F5DA , 0x1412F3 , 0x141322 , 0x141BAB , 0x141BDA , 0x1422C7 , 0x1422F6 , 0x170277 , 0x1702A6
Note: Even after edited the SSID and all other data from @abdulaziz.amar dump file to match mine the factory firmware still don't give me the correct SSID that match my mac address in initial router setup.
For people that want to use 4AGE stock firmware on 3GV2 there is an unofficial patch to firmware 2.28.132 which I got from
This Post
Which are from
This Forum
This 2.28.132 patch really helpful not only in upgrading 3GV2 and 4AGE with any 4AGE official firmware (After patched to 2.28.132),
we can also using this patch to flash OpenWRT to 3GV2 and 4AGE in Windows x64 with sysupgrade.bin file without using OpenWRTInvasion in linux discussed here and 4A Gigabit Thread.
Instead of using 2.28.132.bin I select the desired sysupgrade.bin file placed in firmware folder of that script.
Unofficial 2.28.132 Patch include full memory backup and restore function
If you already run non stock firmware (OpenWRT) and want to restore to factory firmware using that script backup file, but never dump your SPI Flash before using Programmer tools.
It's time to get SPI Flash Programmer, write someone else dump file, then after set up the router run the Restore Function of that script.
Another Note:
Patching 3GV2 with 2.28.132 and 4AGE bootloader will change some value such as "ssid=Xiaomi_" and "ssid=Xiaomi__5G", this don't affect if initial device real 4AGE (or 3GV2 flashed with 4AGE dump with heavily edited values)..
Hello,
The version of my Xiaomi WiFi Router 3G V2 is:
I used the fimrware of @Gingernut (November 2019).
How to update my router to the last version ?
Use this latest version
Thanks @Gingernut ... it's risk-free ?
Well it should be but I won't guarantee anything sorry.
I obtain that:
Normal ?
Yes, the naming was changed so you have to force upgrade and wipe configuration.
OK, so I uncheck the box "Keep settings and retain the current configuration" ?
Yes and then reconfigure.
Update done. No problem. Thanks @Gingernut
