so could someone advise how to get out of uboot please
dont connect GND until after initial boot up
So the error message when tftpbooting is can't find kernel.
Doesn't matter what I try.
Can someone tell me if my uboot printenv is correct?
This was from today's snapshot, tried both sysupgrade and factory images.
Anyone have a working version as snapshot could be broken.

Very strange. My RT1800 is in production right now so I can’t really do any testing.
My advice currently is to try flashing stock firmware, as old as possible and try flashing the factory. After two reboots of course.
Well that was a painful learning experience,
tl;dr tftpboot the belkin_rt1800-initramfs-kernel.bin
after that flash sysupgrade after scp it to the device.
@neheb my firmware version is FW_RT1800_V1.1.00.005, it's probably something ancient in the firmware causing the issue.
My RT1800 arrived with "Current firmware version: 1.0.00.005"
Updated it with FW_RT1800_V1.1.00.016_Prod_20210723_code.bin
Web interface showed "Firmware Version 1.1.00 build 16 Jul 23, 2021"
Then upgraded it with -factory.bin first, then finally with -sysupgrade.bin (built with Luci) using scp/ssh.
Nice to know you have a -factory.bin that works, can you share it?
Both -factory.bin and -sysupgrade.bin were downloaded from the firmware-selector
https://downloads.openwrt.org/snapshots/targets/ramips/mt7621/openwrt-ramips-mt7621-belkin_rt1800-squashfs-factory.bin
That's not that helpful, if you go to https://firmware-selector.openwrt.org/ and choose Snapshot;
Firmware selector currently shows:
Model:
Belkin RT1800
Platform:
ramips/mt7621
Version:
SNAPSHOT (r22071-3c66ac7e22)
Date:
2023-02-15 20:22:37
The current snapshot -factory.bin does not work on either RT1800 I have here, one has had to be converted via serial, the other is still on FW_RT1800_V1.1.00.005, so which version did you use as the install process is currently broken and I would like to help other users from not having to crack open the case, if the web interface method is meant to work.
It did work for me, all the versions are in my first post.
that version is not even mentioned in the release notes
so the snapshot from the 15th February 2023 worked for you?
that's correct
So I'm currently following your process, -factory.bin was accepted but I'm back in the belkin 17.01 reboot stock firmware.
I'll try a factory reset and report back.
Took three attempts, but the web upgrade method finally worked.
Hi there,
I try this pin layout and I think I always using wrong pin to connect console.
And I installed OpenWRT on my E7350 successful.
I choose 6. Upgrade firmware with code pattern and upload bin file(sorry I forgot which file I upload,kernel or factory).

That is! Thanks everyone for help.
But after I installed OpenWRT,the new problem is wifi can't use.
There has no wireless config, seem the kernel not found wifi chip.(using snapshot image).

This I'm sure is factory image because I only can update kernel using U-boot (sysupgrade can update system but can not update kernel).

New attempt with virgin E7350: (No longer have prior unit)
This time working with a virgin E7350 that came with 1.0.00 build 24 (Sep 23, 2020). The -factory.bin from firmware selector says "upgrade successful" but keeps rebooting to stock, Tried this multiple times.
This one I am willing to crack open if necessary but for now I am trying this as if someone just bought this and have not updated the unit to the most current which is build 1.0.00 build 33(signed -10/04/2022).

The e7350 is a dual boot unit.
So you're getting boot partition 2 load each time instead of partition 1 where you flashed openwrt successfully but it's refusing to boot into it.
Try installing the unsigned latest firmware. And then trying to flash openwrt factory again.
No luck. Installed latest available unsigned firmware (1.1.00.032 - Oct 04, 2022). Then from there in gets to about 33% on -factory.bin on each attempt, says flash unsuccessful and then reboots. Any ideas?
I could open up and serial cable at this point but I'm trying to go about all of this as an "average joe" as much as I can because most users who get this model are NOT going have this skill or desire to open up the unit.
Hoping the Dev's can figure this out. It may not be possible to install it at this time.
I would try the initramfs kernel bin, but that's unlikely to work from the web interface.
What's happening is clear, there's rt1800 and e7350 out there with corrupted boot partition 1 that only boot from partition 2.
Connecting UART allows the uboot to finally format the partition 1 allowing openwrt to install.
Sounds like I'm going to have to open up it up after all then.
