I have two GL-B2200 devices that I flashed ipq40xx/generic firmware on to test and now I want to go back to stock. The problem is that I can’t get ANY stock firmware image to load via UBOOT. It doesn’t matter - beta or stable - no GL-iNet firmware loads. Now I can only load / re-load the generic version of OpenWRT.
Can someone help me with this? I am at a loss and I fear I will never be able to get these back to stock.
That is EXACTLY what I did. Reset into UBOOT, upload stable version for web interface - nothing. Did the same with the beta and snapshot. None of them will load.
I even went so far as to recompile the patched version of UBOOT, found here, and installed and still nothing. The only image I can flash is the generic Openwrt.
I’m still at a loss. I read the debrick page a couple of times and the only specific reference to my mode is this:
For GL-B2200(Velica), the two LEDs are blue at first, then turn white to flash 5 times, then turn blue and stay on.
for when you do the reset. I need something else to go on. If missed it - I’m sorry but a hints and treasure hunts aren’t very helpful at the moment. Some specific guidance would be great!
Gave it a go and no luck. It appears to upload (flashing light) and then reboots and comes back to UBOOT. For the life of me - I don’t understand. Did flashing the OpenWRT 20.02 snapshot break the underlying filesystem?
While I am waiting - If I wanted to try TFTP, do I need to rename the .img file to a specific name (e.g. recover-B2200.img or something like that)?
EDIT: I figured out the filename from the TFTP log. It is asking for “qsdk-gl-b2200.bin”. I’ve renamed the stock and beta versions to accommodate upload and I get the same result - Reboot back to UBOOT. So I can confirm that UBOOT and TFTP yield the same result.
EDIT on EDIT: If I unzip and rename the OpenWRT snapshot (openwrt-ipq40xx-generic-glinet_gl-b2200-squashfs-emmc.img.gz) to qsdk-gl-b2200.bin TFTP takes it and installs it without issue! So - I can reinstall OpenWRT all I want from either UBOOT or TFTP, but I cannot install any of the factory images.
