Cannot Revert

[axpmonkey]

Morning,

I am trying to revert back to stock from 376.49_5. Since upgrading I cannot get speeds faster than 95 Mbps. And, I have Gigabit. I have tried a factory reset. I have even done the whole hold down the WPS button until the light flickers and let it reset that way. But, I still cannot get 95 Mbps. If I use the router from my ISP, I can get 700+.

So, I am trying to revert to stock to rule out the firmware. But, I cannot get it to take. I have tried the latest and the previous version from ASUS and neither applies. I have done resets to factory both before and after flashing, and still nothing. Any ideas? Any help is greatly appreciated.

Thanks.

Just a quick update. I was able to downgrade to 376.49_4. But, I still cannot revert to a stock firmware.

No model, No stock version, No errormezz

Is there a stock 376.3626 for your model ? have you tried that ?

Sorry. I guess that would help. I have an RT-AC68U. I have tried going back to 378.3873, 378.3813 and 376.3715. I will give 376.3626 a try.

And, there is no error message. It acts like it flashes fine. It completes and reboots. I reset everything and it is till on 376.49_5.

Any code 3626 or above requires an update to the bootloader, however, only 3626 (or Merlin 376.49_6_cfeupd) actually does this required update. Once you load either of these levels, you will be able to load any code (older or newer)

Success. Thanks for the help. I was able to get 376.3626 loaded and the updated to 378.3873. As soon as I reverted back to 376.3626 my speeds returned to normal. I may give Merlin another go in a bit to see if the speeds stay the same.
