tweant · July 12, 2019, 11:22pm

Hey guys. I am trying to install OpenWRT but when running following command:
mtd write openwrt-18.06.2-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
I get error:
Couldn't open image file: openwrt-18.06.2-ramips-mt7621-mir3g-squashfs-kernel1.bin!
What may be a problem?

Welcome. Please try to avoid hijacking or reusing existing topics if they are not about the exact issue you have (or a strongly related one), particularly when it's a long topic that had too many posts already.

Anyway

You are using the wrong file name. Your file is 18.06.04 while your command looks for 18.06.02.

If your problem isn't solved, please start a new topic.

Does anyone tried WPA3 with Mi R3G? (Using 18.06.04)

derhelge · August 30, 2019, 3:52pm

Hello,

I received my Router Today, but the one I get have no USB Port.
Is this the Old Version?

I had a Problem with flashing the Developer Software, when I upload the firmware I get "Verification failed" and after a few trys sometimes the 100% Upload "stay there for 5 Minutes" and then I get a error "Upgrade Failed System Error or root partition full"

Anyone has an idea what I can do? I reset the router a few times but every time the same. The Softwareversion on the router is 2.28.8

juppin · August 30, 2019, 4:13pm

Your version without USB is the V2 of R3G and is currently not supported by OpenWRT.
There is a patch on the mailing list, but flashing is much harder and requires a hw programmer as of actual state...

Checkout this thread:

reinerotto · August 31, 2019, 6:34am

That's a real PITA. I have an "old" 3G, which is not so simple to flash, either, but its worth because of all the great aspects of the 3G: Powerful, cool design, good price.
And now XIAOMI makes it even more difficult to flash the "new" 3G.
One could imagine, there is some type of "Trojan" in the org firmware, XIAOMI (?) has to keep alive ...

anon69880279 · August 31, 2019, 9:03am

If you have a choice, I do not recommend XIAOMI products that are difficult to flash or more. There is for example the WR1200JS / WR330 which has the same performance and is no problem.

reinerotto · September 1, 2019, 6:07am

WR1200JS: Discontinued; only 128MB RAM compared to 256MB of the "old" 3G.
And the design of the case no match to XIAOMI.

with the last source mt7621.mk is modified:

new version:

define Device/xiaomi_mir3g
  MTK_SOC := mt7621
  BLOCKSIZE := 128k
  PAGESIZE := 2048
  KERNEL_SIZE := 4096k
  IMAGE_SIZE := 124416k
  UBINIZE_OPTS := -E 5
  IMAGES += kernel1.bin rootfs0.bin
  IMAGE/kernel1.bin := append-kernel
  IMAGE/rootfs0.bin := append-ubi | check-size $$$$(IMAGE_SIZE)
  IMAGE/sysupgrade.bin := sysupgrade-tar | append-metadata
  DEVICE_VENDOR := Xiaomi
  DEVICE_MODEL := Mi Router 3G
  SUPPORTED_DEVICES += R3G
  SUPPORTED_DEVICES += mir3g
  DEVICE_PACKAGES := \
	kmod-mt7603 kmod-mt76x2 kmod-usb3 kmod-usb-ledtrig-usbport wpad-basic \
	uboot-envtools
endef
TARGET_DEVICES += xiaomi_mir3g
...

old version:

define Device/mir3g
 DTS := MIR3G
 BLOCKSIZE := 128k
 PAGESIZE := 2048
 KERNEL_SIZE := 4096k
 IMAGE_SIZE := 32768k
 UBINIZE_OPTS := -E 5
 IMAGES += kernel1.bin rootfs0.bin
 IMAGE/kernel1.bin := append-kernel

   kmod-mt7603 kmod-mt76x2 kmod-usb3 kmod-usb-ledtrig-usbport wpad-basic \
   uboot-envtools
endef
TARGET_DEVICES += mir3g

When i compile old version i have sysupgrade good

With the last version i cannot sysupgrade error is :
**The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform. Select 'Force upgrade' to flash the image even if the image format check fails. Use only if you are sure that the firmware is correct and meant for your device!**

anon69880279 · September 20, 2019, 12:08pm

solved with old version:

1 - save the config
2 - flash with rootfs0 file
3 - reboot ( default parameters 192.168.1.1 )
4 - import the old config
5 - update wifi

after you can flash new sysupgrade …

marciocdb · November 9, 2019, 3:28pm

Has anyone tried 19.07 RC1 yet? Any major issues?
Also, I saw that the sysupgrade is in a .bin format so I can't go from 18.06 to 19.07 directly... Luci doesn't accept that format... Do I need to flash like the first time? With mtd kernel1 and rootfs ?

juppin · November 9, 2019, 3:52pm

This is also a tar file which contains the two bin files... They changed only the file ending.
You need to force the sysupgrade because they changed the compatible name.

tmomas · November 9, 2019, 4:44pm

This topic is for 18.06 only.
Please open new topics for any questions not related to 18.06.

Thanks.

Can someone explain me how to Configure SMBV3?
I do this, and dont know what to do more:
Capture
On software page i see this, should i install this:

Gingernut · December 15, 2019, 12:11pm

Look for the package luci-app-samba and install it.

stefs · December 15, 2019, 2:04pm

I install, but when i plug usb nothing happens, like i dont.
Advices? I try with EXFAT and NTFS and results is the same, like i dont put.

Gingernut · December 15, 2019, 2:48pm

You'll probably need to install a few packages for auto disk mount and filesystem compatibility.

stefs · December 15, 2019, 3:06pm

Can you help me how to do this?

anon69880279 · December 15, 2019, 6:59pm

ntfs … relayd, samba, minidlna + many others

opkg update
opkg install … ( my full list )

I forced it and now it appears bricked, so there might be more to it. Seems like it's in eternal reboot mode.
