A "bricked" phone is a phone that cannot boot because of a firmware (OS) failure. Usually, this happens to corrupted files, changed settings, or failure to update the and App DB. You need to "reflash", or reload, your firmware back onto your Behold if it fails to boot.
This method has been tested and proven to work on the Eternity, and I will modify the method for the Behold's files. NOTE: I do not know if your phone has been updated or not. This was the only version my buddy gave me. If there is an updated version, you can always update after you flash the firmware.

Here is a step-by-step way of flashing your firmware from the bootloader:
A) Requirements:
-Samsung Behold
-USB Data Cable
-Windows OS (if you don't know what this means, you shouldn't be using a computer)
-Behold Firmware (

-A program to decompress the RAR to the seperate files (IZarc is a good one, found here: -
http://download.cnet.com/IZArc/3000-2250_4-10072925.html)
-Samsung Behold drivers (found
here, under the software tab, not sure if it is newer or older version)
-MultiLoader_v5.50.exe (it is an application, not an installer. find it in the .rar file above, in the uploaded files on the bottom of the post, or here:
http://www.samsung-behold.com/how-to/how-to-fix-a-bricked-behold!/?action=dlattach;attach=1245)
Try this step first before part C. This new method partially flashes the phone, and does not delete contacts, data, settings, etc.B) Follow the PARTIAL firmware flash (unbricking) steps (do this method first)
Steps:
1. Put your bricked phone in bootloader mode by holding down the red power button and the down volume button at the same time until the screen pops up.
2. Open up Multiloader v5.5 and under the "control" box, select "MSM6275/MSM6280/MSM6290"
3. Plug your USB Data cable into your phone and into your computer (at this point port numbers should show up at the very bottom and the Download button should be highlighted, if not, do a "Port Search.")
4. DON'T check any of the boxes above that say, Boot Change, Full Download, etc.... Boot and Apps should be the only tabs not highlighted below.
5. Click on the "Amss" button and locate the Amss.bin folder and then click open.
6. Click the "Rsrc1" button and locate the Rsrc.rc1 file and then open.
7. Click the "Rsrc2" button and locate the Rsrc.rc2 file and then open.
8. Click Download and the phone will then be reflashed. ( don't disconnect the cable until it tells you it is completed and the phone restarts.)
After the restart your phone should have all your personal data and settings the same.
C) Follow the FULL firmware flash (unbricking) steps (only after you try the partial flash first!)
Steps:
1. Put your bricked phone in bootloader mode by holding down the red power button and the down volume button at the same time until the screen pops up.
2. Open up Multiloader v5.5 and under the "control" box, select "MSM6275/MSM6280/MSM6290"
3. Plug your USB Data cable into your phone and into your computer (at this point port numbers should show up at the very bottom and the Download button should be highlighted)
4. Check the box that says "Full Download."
5. Click the "BOOT" button and locate the boot folder which is located in the firmware file that you downloaded earlier and click open. (Note that the folder won't show any contents but the contents are there and will be used.
6. Click on the "" button and locate the Amss.bin folder and then click open.
7. Click the "Rsrc1" button and locate the Rsrc.rc1 file and then open.
8. Click the "Rsrc2" button and locate the Rsrc.rc2 file and then open.
9. Click the "Factory FS" button and locate the FactoryFs.ffs file and then open it.
10. Click Download and the phone will then be reflashed. ( don't disconnect the cable until it tells you it is completed.)
The whole process only takes about 2-3 minutes and then it will restart the phone and then you will be prompted to calibrate the touchscreen. After calibration then you are in business!!!
