So, I am now the proud owner of a Brocade TX24. Or at least, that what the system tells me :)
@fohdeesha talked me through the process, but it was actually pretty easy, once I got it going.

Before we could get started, I had to solve some other problems: I was using a usb-serial adapter on my macbook which gave garbled output. Switching to an old Xubuntu laptop using screen helped.

As @fohdeesha stated above, the actual flashing is only two commands. You copy two files to a TFTP server (I used my Synology) and the LB6M boots from there. Then you copy the running Brocade bootloader over the Fasthpath boot loader. Finally, you start the actual Brocade TX24 OS and write that to flash.

After flashing successfully, we shortly tried a few different settings such as inter-vlan routing (which is now pretty easy to do!) and setting vlan ports. I have not stress-tested the switch yet, but this will now become my new core switch, now that inter-vlan routing works, so that stress testing will follow in a not-too-distant future.

Lots of thanks to @fohdeesha and crew for figuring this out!

Following some output from the 'new' switch:

@fohdeesha Thanks for your help in flashing a LB6M into a Brocade TX24, once I got pass the laptop problems all went smoothly. As @fvanlint posted a few commands, I guess I should also. Ambient temp is 30C.

New member here but anxiously awaiting this documentation! I don't have any 10Gb equipment yet but this is seriously looking like it might be a really good excuse to start lol!

just got done with fvanlint on discord, he helped us get all the extra output we needed for verification steps and got his succesfully turned into a full L3 TurboIron and was able to get vlan routing working in about 60 seconds.
I'm confused. On my LB6M I'm already routing between VLAN's just fine. What I don't have, that I'd like, is IPv6 routing.

Sorry, we meant that it's much easier and more intuitive to get working now, not that it was impossible before. No IPV6 routing that I know of

fodeesha that is truly awesome work. Props for being very determined and also especially collaborative. I imagine you are an excellent engineer and so young too. An excellent career awaits I am sure.

Not sure if this is relevant, but will turning the LB6M into a Brocade help to control the fan noise better?

Nice work! Should I try this method to replace Delta DT7024 bootloader with Dell 8024 bootloader without Jtag?

if the 7024 loader is uboot, it should be possible, but the bootloader staging and copy addresses will most likely be different. I'd be willing to jump on discord or google hangouts with you and figure it out when I have a moment (assuming you have access to a 7024 because I do not), I have seen a few people who have been wanting to do that without jtag

Thanks fohdeesha. I would need some helps from @Terry Kennedy.

Hello!

I was wondering if this sceneario is possible and if it is the best one for a highly available network.
If I had two LB6M, can they stacked by two or four 10G port?
Does LB6M support LACP port-channel across two switch unit?
I want my storage server use dual 10G port to two LB6M by LACP/LAG.

Thanks!

if you flash it to brocade firmware, it supposedly supports stacking, which syncs the management plane between the two switches. Then you can use "active-active" failover in freenas or the like (different from plain LACP if I remember right, which would NOT be supported across both switches witohut explicit support for MCLAG)
