    Well, what if we just did that? I wouldn't be surprised if they were the exact same phone, and we could get our Donut on.

    UPDATE: We need someone to try the steps below.

    You can just unyaffs the galaxy system.img from a firmware file over your system partion if you can adb in recovery. Thats not very risky.

    They seem to be the same phone except the behold has 128mb more RAM (total 320mb, and doesnt have the internal 8gb storage.

    If i had a choice i'd take the RAM! anyone wanna swap their behold 2 for my galaxy :p

    I'll track down that img for someone to try. I don't actually HAVE a Behold 2, I'm just recommending it to people right now, under the assumption it will be rooted or hit 2.0 OTA.

    Ok, here are kam's steps for the Galaxy that I just shamelessly ripped off.

    - Copy the system.img onto the root of your sdcard (mount it in windows, and drop it over)

    - Boot into recovery

    - open an adb shell
    # adb shell

    - remount system read/write
    # mount -o rw,remount -t yaffs2 /dev/block/mtdblock1 /system

    - erase the system partition
    # rm -rf /system/*

    - Extract the system image:
    # cd /system/
    # unyaffs /sdcard/system.img

    The boot images are identical, so there's no need to flash that over. You probably want to do a factory reset first to clear out your data partition etc. You can take a nandroid backup first of course in case you want to revert back.

    Here's the img-
    MEGAUPLOAD - The leading online storage and file delivery service


    Ok, we need someone to try this. Since you won't mess with the radio, it's unlikely you'll screw it up, but I'm not responsible if you do. I'd do it myself, but I don't have a Behold 2. Does someone want to take the brave first non-rooting steps into Behold 2 dev?

    I suspect that this will work, its the exact same phone save some internal storage and a cube button.

    I can't get anything to go in recovery except deleted all of my data by accident :( adb can't see the device in recovery mode, just shows a picture of an exclamation mark next to a phone

    I have been trying everything I could think of to get a custom recovery image on this thing, I tried the method over at MoDaCo for the i7500, but it seems to me the phone doesn't have fastboot, or atleast not one that I can access, because following the instructions, Green + Red on startup which is supposed to go into fastboot does nothing but start up normally. Recovery mode and Download mode work fine though. I also can not get FlashRec to work at all it keeps telling me "Could not run command"

    I am out of ideas..... anyone got any?

    Right, we need a custom recovery image now. I'm afraid I'm not capable of doing that at all.

    It would be interesting to see if you could upload a recovery image using odin.

    Do you guys have a firmware update for the behold 2 yet? If not you can grab your existing partions and make one.

    Jump on irc chat chat.freenode.net channel #i7500
    or click 'chat' in the forum bar above and type /j #i7500 when you're in

    I'll talk you through what u need to do :)

    Sadly, as I said before, I don't have a Behold 2. If any new Behold user out there wants to help get this thing going give it a shot!

    I'd like to help, but I can't get the SDK to recognize the phone in either ArchLinux or Windows 7. :(

    Settings>Phone Settings>USB Settings - Samsung PC Studio

    then

    Settings>Application Settings>Development - USB Debugging

    make sure you have the device installed using the ADB drivers from the SDK

    kam and I were trying to get something flashed on the Behold a few days ago with no luck. The security system Samsung has on this phone seems very complicated. Any changes made to the /system folder are erased on boot, as well as the recovery partition. I attempted to load the Galaxy recovery image through Odin, while it successfully flashed, it was immediately overwritten with the stock recovery image on reboot.

    Also for reference fastboot seems to also be disabled, as the usual end call+call button on boot does not work.

    Every other phone I've used was Camera + Power. I tried this in the B2 and nothing showed on the screen but the phone vibrated every one second for as long as I was holding down those two... interesting.
