Firmware update problem (from ~1.8.1.7 to 1.9.2.7)

[lukie]

Hi There!

I want to upgrade to FW 1.9.2.7 because of its 'bandwidth management' capabilities i need. I can't upgrade. After uploading of the firmware i waited 5min. Tranfer successful, PLED was on. Waited. Router was not accessible via browser.
I pushed the reset switch on the back of the router. The PLED didn't flash fast and for a short time like it should. It flashed slow: Recovery Mode was turned on. O_o Router was not accessible. But the switch/hub functionality still worked.

I downloaded the FW 2 times from asus.de and 2 times from chupa.nl. No one worked.

I tried different approaches:
-Upgrade via web interface
-Upgrade in automatic recovery mode with recovery tool
-Upgrade in manual recovery mode (hold reset + plug in power; then release reset) with recovery tool

I tried different Firmwares:
1.6.5.3 works
1.7.5.6 works
1.8.1.7 failed
1.8.1.9 failed
1.9.2.7 failed

Now after searching this forum and more than 3h trying around i got no more ideas. Someone can help?

Thanks in advance

Most likely you just need to reset your router to defaults AFTER the upgrade using the RESTORE button to access web interface.

also be sure to UNZIP/UNRAR the files

After the upgade i pushed the the restore button on the back as it was said.
After this the PowerLED started blinking, i had still no web access and the router was instantly in 'restore mode'.

And yes, i used the *.trx files. Firmware 1.7.x.x worked, firmware 1.8.x.x and 1.9.x.x didnt work.

I also tried the recover and clear-nvram firmwares.

try rebooting your asus before you upgrade the firmware. Or just cycle power prior to upgrade the firmware. that way you know you will have maximum amount of memory available.

Also reset to defaults once the upgrade was successful

Thank you all for your help.
But it still doesn't want to upgrade.

The flasher says the upgrade was successful. But after doing a reset via the 'restore' button, the Powerled flashes slowly and the router is in 'recovery mode'.
