What revision is the tm-ac1900?

[sorinut]

I have flashed my t-mobile tm-ac1900 to a rt-ac68u and have been running Merlin. I want to flash the LTR firmware to it, but I'm unsure what revision it is, or if the firmware would work.

I see that only Rev A1,A2,B1 can use it.

The AC1900 uses the same hardware as the 68U, the firmware you already flashed. So, for Johns fork this would be: RT-AC68U.

That's what I need to know. Thank you!

Usually they are HW revision 1.70, which means you can flash the 1.0.2.1 CFE, and run Johns fork.

There are at least 5 HW revs, all labelled AC68U...A1, A2, B1, C1 and E1. C1 and E1 are not supported by my fork since they require a later SDK.

I only know of one 'exclusion' test if you are already running Merlin. Look on the Tools > Sysinfo page at the CPU Model. If it contains 'C0' as part of the string, my fork definitely won't work.

TIL things about my router...

I downgraded the CFE to 1.0.2.0 when switching to merlin from the default t-mobile firmware, is that version okay?

Here is my CPU info, so it looks like I'm good: ARMv7 Processor rev 0 (v7l) - (Cores: 2)

Guys,
Want to bump this again.
I did read whole thread, but I didn’t get it still.
What is tm-ac1900 hardware version?
Tools - System Information show:
Bootloader (CFE) 1.0.2.1
CPU Model ARMv7 Processor rev 0 (v7l) - (Cores: 2)

I see, John put a file into 28L2 Legacy 'L' Build:
@RT-AC68U 'L' build only supports rev A1,A2,B1.txt
I'm pretty sure, 28L2 will work on tm-ac1900, but better be safe, you know...

BTW: According to 1st port in this thread, tm-ac1900 cannot run Merlin at all (due to incompatible hardware?)
Yet, I do run 25E1 somehow...
