Attempting to restore factory firmware on GL-B2200 returns to uboot

atownlede · 2022-06-01T00:47:32.778Z

I’ve installed OpenWrt 22.03.0-rc3 on my GL-B2200, and now I want to go back to GL-iNET stock factory firmware to check on something. I’ve downloaded various firmware options from GL.iNet download center but none of them load correctly via uboot.

I can load and boot a replacement OpenWrt image file just fine, but the factory firmware doesn’t boot up, instead the hardware returns back to uboot.

I’m guessing there’s something else that needs resetting (partitions on the flash, perhaps). Any guidance how to do that on the GL-B2200?

The .img file from the download link should just be work if you flash on uboot.

I don’t see a reason it does not.

I updated uboot from GitHub - gl-inet/uboot-ipq40xx, in case that would make a difference, but nope. I can still uboot-web update to openwrt 22.03.0-rc3 images, but not to gl-inet downloaded images–those fail to start and the router reboots back to uboot.
Any suggestions on how to diagnose what’s going on?

Can you tell me your email?
There must be something wrong with the partition table.I will give you a firmware and you can restore the partition.

@lizh did you get my private message?

I have sent you an email, Does it solve your problem?

atownlede · 2022-06-23T11:38:24.564Z

Yes, thanks! That worked just fine. Is this something you can post publicly so others can access it if they need to switch back from OpenWrt firmware to your firmware?

GL-B2200 Velica bricked Technical Support for Routers

Hello, After reading the previous posts about it, it seems I need to recover my router partition table. Could any staffer give/send me the file? Please. Kind regards @lizh

I ultimately uploaded both norplusemmc-ipq40xx-single.img and 3.216 SDK to uboot and ran those. When checking mount points in LuCI, I can see that /dev/mmcblk0p4 (originally mounted as /data with 6.39GB capacity) is not available. What I am doing wrong and how can I revert to the original setup?

lizh · 2024-06-24T10:31:48.247Z

Hi route66:

Please check the file system type of /dev/mmcblk0p4:

image1551×129 8.18 KB

If it is not 'ext4'.Please exec the following command:

mkfs.ext4 /dev/mmcblk0p4
reboot

route66 · 2024-06-26T03:44:26.413Z

Thanks! Formatting to ext4 indeed made /dev/mmcblk0p4 available again.

It is very aggravating that the partition table image is not made public. can you please send to me.
