HooToo HT-TM01 - How to flash Stock Firmware?

Tried this, no go. Basically after I power on the unit, regardless of holding down the reset button or not, both the Internet (yellow) and LAN (blue) LEDs go on SOLID and nothing happens from TFTP...

Do you remember how did you flashed that factory.bin file?

I flashed that out of LUCI Gui.

Thanks for all your help you're offering here, xabolcs! Actually, re-reading the original thread title here, I'm afraid I've mislead you:

I had actually home come here to learn and document how to go from stock TM01 to OpenWRT 19.07 or higher :slightly_smiling_face: And honestly, I'm still confused about how best to do it safely, as I'm not knowledgeable about U-Boot and rootfs.

So, in order to install OpenWRT 19.07 on a stock TM01, am I hearing you recommend to install your 1536k kernel + 6144k rootfs files using the usual TFTP server (at which IP address?), instead of simply flashing ht-tm02-initramfs-kernel.bin linked on the new HT01 device page stub: Is this correct?

I will try to reproduce your issue with my HT-TM02 and HT-TM01, but your case isn't an easy thing. :frowning:


For installation see the "snapshots and recent releases" TFTP method of RP-WD03.

Allright, xabolcs, I'm getting ready to test and document the OpenWRT installation on my TM01 using the TFTP method for the RP-WD03 :sweat_smile: Final questions for clarification:

  • Would script EnterRouterMode.sh at the rp-wd03 page on openwWRT be recommended to get a working backup of the TM01's stock FW?
  • your kernel and rootfs binaries at GitHub are for the TM02. Would they need any change to fit the TM01?
  • Is anything to be done about the manifest and sysupgrade files there, or do they just indicate what's already incorporated into your binaries?

Yes and no! :upside_down_face:
Yes, it's recommended, as it does the job in a good way.
No, I don't recommend it, as there is a better script for that, which does that backup stuff in a more nicer way! :grinning:

There is an EnterRouterMode.sh which I recommend and does the backup in a more descriptive way:

$ ls -lgG backup-fw-WiFiSDRJ-RAV-WD02-2.000.032-8850108874/

They are ready to use.

manifest is just a "for your information" file.

sysupgrade.bin is the sysupgrade image ... but it's currently useless: there aren't any other version of my community build, and my build is incompatible with the official build.

Sysupgrading back and forth between the official image and my community build causes softbrick of the device. Don't do it!
For switching between official release and my community build one should use the TFTP method.

So I've got it to work. With enough horsepower and memory to run shairport-sync :slight_smile:

Great xabolcs that you have provided 19.07 binaries for the TM01. Thank you for your kind help! (BTW snapcast is cool — mpd... nice... — but runs shairport-sync anyway when streaming from Apple devices. Actually, would the TM01 have enough free memory to run snapcast?)

Happy to document the steps I took on the TM01 OpenWRT ToH page.

Actually I wonder what would have happened if we had simply installed the "official" TM02 19.07.7 images that are linked on the Hootoo Tripmate OpenWRT page using the TFTP method? Should these references be deleted when editing the page?

Or should the link to xabolcs' binaries be added on that page? I wonder how to articulate the difference between the two firmware versions to readers.

I think it will overwrite the params partition (one of the device specific partitions of your device) and of course softbrick it! :grinning: Without backup. :see_no_evil:

initramfs.bin images should be used through serial access in U-Boot, and not for TFTP recovery!

Yep, those initramfs-kernel.bin files should be wiped from the "Firmware OpenWrt Install URL" column!

Leave it empty and let my builds noted in other sections of the page.

I've added installation instructions to the TM01 OpenWRT page. Feed free to add any improvements.

Hi there, any chance you had any luck to replicate my case, and a solution to unbrick?
Thank you

Thanks for the follow-up and sorry, I was busy in these days!

OK, so I have a HooToo HT-TM01 (firmware v2.000.046) and I would like to switch over to OpenWrt using the instructions here. However, unfortunately I'm failing on the first step, to create a system backup :frowning_face:. I've created the file "EnterRouterMode.sh" (case sensitive I presume) with the code from this post and copied it onto a 1GB USB stick. With the TM01 powered up, I insert the USB stick and wait for the status light to stop flashing (I also tried much longer than that). However, the folder with the system backup files is not created. It only creates DLNA related folders. I've tried resetting the TM01 and I've tried a FAT and NTFS formatted USB stick, all without success. Does somebody know what I'm doing wrong? Thanks in advance for your help.

1GB could be to big.

Partitioning might be of importance too.

Found the solution, as per jekagan's post here:

If you copy the code for the script, make sure your text editor uses UNIX line endings (0x0A, i.e. \n), and not Windows line endings (0x0D 0x0A, i.e. \r\n). The script wouldn't work for me until I changed this. If you're on Windows, this is simple enough to do with Notepad++ (or your editor of choice). In Notepad++, choose Search -> Replace, then make sure "Extended" is selected for Search Mode.

Find what: \r\n
Replace with: \n

I'm up and running :smiley:. After following the instructions here, I changed the LAN IP address, configured and enabled the wireless network, connected my laptop to the new wireless network, removed eth0 from the LAN interface, created a WAN interface with eth0 (DHCP), wired the TM01 into my 'upstream' network, and at that point it worked as a router. I then installed the TravelMate package, which allowed me to create the wireless WAN client connection. Last step was to install the OpenVPN client. All working well so far. Not fast when I use the wireless uplink rather than wired, but that's not surprising given it's using a single wireless radio.


Hmm. I was reading an old topic, and found this:

@arrmo 's device was a HT-TM05 (the red one) and reading again both your comments they look similar :confused:

Looks like you had to reprogram your device's flash chip with an external programmer.
At least you have backup. :see_no_evil:

I've noticed that apparently, the installation instructions to flash Stock Firmware on the HooToo HT-TM01 have a new URL.

Here's the correct URL for the OpenWRT installation instructions on the HooToo HT-TM01.

The link in my original post and in AberDino's report of a successful installation now seems to point to a nonexistent page.

I have now added a redirect from old -> new URL, i.e. old and new URL are working now.


This is how to restore the factory firmware of HT-TM02 using TFTP64 tested and worked, thanks for all the people contribute the resources:

  1. Download MTD bin backups (4~8) in step 2 from: https://drive.google.com/drive/folders/1XiEWeimv5pPtHeueD4U0fTVdcnYSKeeL

  2. now on windows, you can do the following to get the 2 files required for the refresh
    copy /b mtd4.bin+mtd5.bin+mtd6.bin+mtd7.bin kernel
    copy mtd8.bin rootfs

  3. Follow the Youtube tutorial but need both 2 files: kernel & rootfs, set the ip, plug in network, hold the reset then power on for 10~15 seconds then wait a few minutes will auto-refresh:

  4. If you want openwrt, you can download wingspinner's firmware & rename it to kernel for update:

Not sure if TM01 will work since I don't have the unit, enjoy!!
