Missing v3.104 firmware for unbricking AR730S

[Radders]

I have an old Slate that I am reconfiguring. It was on version 2.X but it had issues so I have tried to upgrade to the latest. I tried the images from the download centre, and the only one that worked was version 3.0 Clean (without LuCI). The other images ran into the old issues of the image sizes being too big for the Slate uboot to handle.

I have read multiple threads about unbricking and updating the Slate (see below). I also updated uboot to uboot-gl-ar750s-20201222. However, I need image 3.104 to complete the process, and this is no longer available in the download centre so I am stuck.

Does anyone know where I can find the image, or know of any other way to get the Slate to update to latest?

Threads I have been following:

One thread to rule them all: GL AR750S (Ext) Slate - Firmware Update Problems

Hey there, I’ve just had a heck of a time trying to debrick a GL-AR750S-Ext (Slate) router, and thought I would collect my observations in one place because I had to search through like 15 threads on this forum to figure it out. I do finally have a working Slate with the latest 3.212 firmware, but I had to try, try again, give up, and try again some more before arriving there. If you are experiencing the following problems updating Slate firmware: In UBoot update, update hangs with “UPDATE I…

Unable to Uboot update AR750s with 3.105 but with can 3.104

I can’t, it shows an error with file being too large/small. I ran into this long time ago and think I flashed with 3.104 then upgraded from there. All firmware I get from the download site does not work.

AR-750 Slate is a brick again - HOW do I get it unbricked?

I don’t see anything obvious in here that covers what I’m getting… I downloaded the firmware file as instructed: openwrt-ar750s-3.212-0407.img I watched the video. I changed the address to 192.168.1.2 I held the button, plugged in the power, it blinked 5 times, I let go of the button. I put 192.168.1.1 in the address and the “Firmware Update” screen appeared. I CHOSE the file I downloaded. I clicked Update Gl-Inet Firmware. I sat back and waited, and got UPDATE FAILED. At THIS POINT, I…

Thanks in advance!

I was one that have the file size issue. Updating the uBook fixed it. Follow the instruction from alzhao in the second link above.

I did that, but it still failed on the 3.105 image. I will try again and report back.

If you have already update the uboot, you don’t need 3.104. Just use 3.105 and later.
