I thought maybe I had bad usb's so I just went out and bought new ones, still doesnt work

the command I am inputting is

dd if=/users/alfaro27/Desktop/USB1.img of=/dev/disk2 bs=4096
it tells me the files have transferred

"1280+0 records in
1280+0 records out
5242880 bytes transferred in 1.921392 secs (2728688 bytes/sec)
new-host-3:~ alfaro27$ "

I eject the drive using disk utility

and when I install it into the gtv and attempt to use it It tells me
"cannot find usb memory or update data
press any key to exit"

Take a look at this it may help you.
It says to make sure and unmount not eject.


Mac
dd

Find your USB key open /Applications/Terminal and type:


df -h

You should get something like:

Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s2 74Gi 68Gi 6.4Gi 92% /
devfs 121Ki 121Ki 0Bi 100% /dev
fdesc 1.0Ki 1.0Ki 0Bi 100% /dev
map -hosts 0Bi 0Bi 0Bi 100% /net
map auto_home 0Bi 0Bi 0Bi 100% /home
/dev/disk1s1 3.7Gi 896Ki 3.7Gi 1% /Volumes/USB2

You can see that a USB stick with the volume name USB2 is /dev/disk1s1

We want just the disk device name, and that is /dev/disk1

REMEMBER TO USE DISK UTILITY TO UNMOUNT (not EJECT) THE USB DRIVE !

dd if=joggler_unr_9.10_v1.3a.bin of=/dev/disk1 bs=10485760

Notes:

1) bs=10m (note lower case m) for OSX's standard dd [2]

2) bs=10M (note upper case M) if you use fink or mac ports

3) bs=10485760 for both

And Wait ... probably 20-30 mins if you have a horrible usb hub :)

OSX will probably recognise the EFI partition after dd has finished writing it, so remember to eject the flash drive from finder before removing it.

Per the guide I believe you just boot in to the restore screen & do a factory reset & it will restore it to original & get rid of the hacked boot screen & root.

What brand of memory stick are people using? I just bought a unit today, (Package version is 2.1_2010081002F, GoogleTV build is 2.1-20100810.123847 and Recovery mode is 20100806|699) I am trying to USB update it to 3.2 through recovery and I keep getting a "update data error". I've tried a 2GB Kingston DataTraveler, a 4GB Sandisk Cruzer, a 4GB PNY, along with several hard drives but none seem to work. I am afraid to do the OTA because of the chance of getting the new update. Any help will be appreciated.

Off topic for a sec, but I just want to say thanks for the hard work put into exploiting these. I read the wiki and its great! I'm going to root my NSZ-GT1 soon thanks to you guys.

@Llama I ordered 4 Centon 8GB drives and will be using them. IF anyone could let us know what are some working flash drives (brings me back to the old Xbox softmod days)

this may be a stupid question, but people are using fat-32 formated drives right?

I've tried fat and fat-32. I can't get any updates to install, but it will read the downgrader files off the same USB sticks. Now I'm half-bricked, I get a black screen on start and can only boot into recovery. I have the GTVHackers splash screen, but System Info shows me as having no package version and no Google TV version. Hopefully if I can find a way to flash an update I can fix this.

I'm beginning to think my box must have been updated and I can no longer downgrade and root =(

When you use 'dd' it auto formats the USB sticks for you: fat32 and ext3
there is no need to format just use dd
but if you are upgrading your firmware from say 3.1 to 3.2 I'd assume you need to use FAT32
