Asus the File Transferred Is Not a Valid Firmware Image

Asus the File Transferred Is Not a Valid Firmware Image

I would to thank anybody who has contributed to this thread. I received my TM AC1900 yesterday and battled three hours trying to downgrade the firmware. I resolved the trouble from a “hint” on ane of the above replies.
I was using the recovery mini online method to load TM .1703 firmware.

I could choose a file but download never would work and stopped in different ways.
The solution for me that worked was I STOPPED USING CHROME and turned off the anti-virus plan.
Pushing the reset button subsequently the first viii seconds didn’t work either and was not needed using Firefox .
I used my 64 chip win7 HP laptop.

Everything turned out well and thanks over again.

Engineers’s instructions are very wordy and tended to put me asleep only every bit I remember what I was doing wrong when I had you lot problem was in this footstep when resetting it.


  • Ability router off

  • Wait 10 seconds

  • Press and hold the WPS button

  • Power the router back on while standing to hold the WPS push button for 15-20 seconds

The issue is that
mtd-write -i new_cfe.bin -d boot
does not appear to be doing anything.

Bold that you have copied the mtd-write executable to the router, and have information technology nowadays and marked as executable in your current working directory on the router, then the right command is:
./mtd-write -i new_cfe.bin -d boot

Detect the
./
prefix there!!

Spent last two hours converting from T-Mobile ac1900 to AC68. A lot of steps to go through, but got it done with out any major problems. Running latest Merlin Fork 26E3 firmware.

Instructions are very detailed, I think some info should be omitted, simplified and clarified. But they are dummy proof instructions for people that accept never flashed firmware.

Side notes;
1. mtd-write version two and mtd-write version 3 didn’t work for me at all.

two. Had to redownload mtd-write version i several times to get it working.

3. Once you install Asus firmware 376.3626, yous tin can install ANY firmware using “Mini-CFE Webserver”. I call up this should accept been mentioned more than clearly, so y’all not flashing four firmwares just so you can install Merlin Fork for example.

4. Yous can rename your USB stick to make it easier when typing commands in Telnet. I plugged it into my PC and renamed it to USB_NAME, that allowed me to copy and paste all commands.

five. After inserting USB stick into the router, it automatically mounts information technology self, I didn’t realize it and tried to notice a mode to mount information technology, instructions were unclear on that role.

Thank you goes out to all the people that made this conversion possible.

I ran the TM-1900 to RT-AC68U modification this weekend and specifically created an account on SNB and so I could come up thank RMerlin, Engineer, and the others who contribute so much time to this and similar topics. I used information from all of y’all and information technology went very smoothly, and then thanks.

I do have one question. I was very uneasy using the links here on SNB to download CFE and the other tools linked in the tutorials. I haven’t seen anyone question the source of these files, and I personally take no way to validate that they are safe (not infected). Other than relying on three years of conversation in this and other threads, how do you bank check to make certain a version of CFE you lot download is safe?

Cheers in advance for an reply, and I hope some interesting conversation.

The same manner you verify any file you download from the internet, with an antivirus program.

Thanks for taking the time to reply. Perchance I should have mentioned that I scanned these files, but my question is more about the nature of a tool like CFE. How exercise you verify there haven’t been scripts added to startup, etc., that might mask a root kit, undetectable to a virus scan. It wouldn’t be a virus, just a linux startup script to set certain parameters. Non having access to download the file straight from Asus, how do you validate where it came from and that it hasn’t been modified?

Verifying the checksum, if they’re published

Deplorable to bump up this old post. I’g badly in need for help with the newly purchased (refurbished) TM AC1900.

I was able to follow Alex’southward Instruction (from Bay Expanse Tech Pros) and flashed the router to AC68P. Everything worked until…….I tried to flash the latest Merlin while a external difficult drive was plugged in. The flash wasn’t successful because of the external USB device. I unplugged and restarted the router trying to become information technology rolling again, only to find out the router was reverted back to TM firmware 3.0.0.iv.376_3199. It was never flashed to Merlin and somehow the AC68P was flashed to 3199.

Fine, I thought no big deal merely re-practice the whole thing. So I started the process over again… I could become in mini CFE no problem (following the didactics provide hither), but I keep getting
“Receive file size=16949294. This is not a valid firmware image”
…. I’ve tried switching all 4 LAN ports. merely no luck so far….

I tin yet become in the router interface and employ information technology equally Tmobile…which feels lame….I’ve tried every possible fix I could notice online. Did I broke the router?

Any thoughts?

Sad to bump upwardly this old post. I’m badly in need for help with the newly purchased (refurbished) TM AC1900.

I was able to follow Alex’s Instruction (from Bay Surface area Tech Pros) and flashed the router to AC68P. Everything worked until…….I tried to flash the latest Merlin while a external hard bulldoze was plugged in. The flash wasn’t successful because of the external USB device. I unplugged and restarted the router trying to go it rolling again, only to find out the router was reverted dorsum to TM firmware 3.0.0.4.376_3199. It was never flashed to Merlin and somehow the AC68P was flashed to 3199.

Fine, I thought no large deal but re-do the whole thing. Then I started the process again… I could go far mini CFE no problem (following the education provide here), simply I keep getting
“Receive file size=16949294. This is non a valid firmware prototype”
…. I’ve tried switching all 4 LAN ports. but no luck so far….

I can still get in the router interface and use it as Tmobile…which feels lame….I’ve tried every possible fix I could find online. Did I broke the router?

Whatsoever thoughts?

Asus has fabricated changes to CFE in the new firmware. I think basically speaking your router has been unsupported. You lot may have to employ johns fork. The CFE is encrypted so no mods can be made. Asus is clamping down on non-supported routers. By the way
@RMerlin
never supported this model ever.

Further, having similarly spent 4 hours yesterday trying to perform this phenomenon, I think Asus may exist trying to get users who are looking for the functionality of their products to actually
buy some
rather than hacking the stuff they re-purposed for customers. I tried everything I establish online, and even considered putting the tinfoil hat on and holding my left arm up in the air while continuing with my right leg off the ground during the reset/recovery powercycle.

Okay.. I have to admit Asus has all the reason and maybe the rights too to do so….

so basically I can’t downgrade it to 1703 anymore. And flash it to AC68U just became a mission impossible. I’ll look for John’due south fork and see how far that could go me to.

Well although it’southward not supported or recommended past it’s creator, 384.4_2 works very well in the TM-AC1900. It did take me awhile to get it to take the mod and I retrieve I had to edit the CFE file with the settings from my router. I still accept the original CFE file for mine and that would be where I think I wound begin. You need to get information technology to take the original CFE file and firmware dorsum. I think that would be your only way.
I still accept the tmo firmware and setup files from doing that mod. The firmware is TM-AC1900_3.0.0.4_376_1703-g0ffdbba
