Mag254 Software Update "wrong signature"?

Dunno if this will help, but came across a similar issue with "Wrong Signature" message when installing a newer firmware via USB stick on a MAG254 and it turned out to be the USB stick. For whatever reason, changed the stick and it worked. Also ran into a "unsupported architecture" message and discovered the imageupdate file was actually for a MAG250. Verified by opening up the imageupdate file using "EditPad Lite" and looking at the STB Model:MAG254 string. Got the right public FW and all went well.

i have same problem after factory reset, wrong signature, just got box off my mate who did not want it, is there any software updates and how to do , as i am new to this, my box is a mag 250, just been reading up on this sight today

After factory reset, I am also getting wrong signature error. sometime update image process freezes at any percentage. Any help will be greatly appreciated. Thanks

I use a 'HTTP' update mehtod .It's via WIFI internet from 'infomir ' site ... My current version is r-14.

Ok you have flashed a non custom firmware or been shipped with it. Heres how to solve :)

unplug the power
hold the home key
power on to blue screen with options
goto default settings then ok
then goto factory reset twice then reboot

Boot into the blue screen again then select boot = nand
save and reboot

all will work perfect now but your settings will need to be re done

Hope it helps :)
