Hello,
I'm trying to use the latest sprint firmware update however it fails at 11% every time - the phone reboots at 11% and I get the error on the sprint firmware saying error 290- -invalid command. I read their update document that covers lots of other errors but not 290. Any tips? I've tried several times - I'm stuck at the red green blue white screen.
I used the unstucker
in imcokemans folder and it worked great for getting it out of bootloader mode.
PS - sorry for the post -I found the same question here -
http://forum.ppcgeeks.com/showthread.php?t=20782&page=2 - thanks to this I found the solution - just relock the device (relocker found in imcokemans folder). after relocking I was able to update the firmware.
