== Before to start ==
''To restore TV using u-boot you need:'' 
1. Settings in Service menu are set before TV broke - do it now, if your TV isn`t broken - insurance for future :)
* Enter Service Menu ( quickly push [INFO] [MENU] [MUTE] [POWER] on your remote control )
* Change setting for your RS232C interface to "'''debug'''" ( Control -> Sub Option -> RS-232 Jack -> [ '''Debug''' | UART | Logic ] )
* Change setting for Watchdog to "'''off'''", so that the device doesn't reboot while you are in uBoot menu ( Control -> Sub Option -> Watchdog -> [ on | '''off''' ] ) 
2. Make or buy '''Service Cable''' - [http://wiki.samygo.tv/index.php?title=Enable_Serial_Console_on_non_CI%2B_Devices#The_Ex-Link_.28serial.29_cable ExLink][[Image:ExLink.png|200px|thumb|left|ExLink cable]]
3. Get [http://wiki.samygo.tv/index.php?title=Getting_access_to_uBoot_/_bootloader access to u-boot] 
Here you can get in trouble because of samsungs latest firmware - if you have upgraded your TV to it (all firmwares after 25.1.2010), chance to get access to u-boot are equal to 0, because the latest firmware deletes partitions from TV to disable u-boot and TOP Debug console. If you are lucky and you didn`t upgrade TV to [http://forum.samygo.tv/viewtopic.php?f=1&t=433 post Februar firmware] or you have restored u-boot by hand, you can do next steps to restore TV. 
4. '''Images''' to restore (or dumps of partitions you made before. How to make dumps [http://wiki.samygo.tv/index.php?title=Dumping_and_Flashing_images_by_hand read here].) 
Files you need exact for your model, you can`t use images from other models (with little exceptions) 

=== Images to restore ===

As usualy TV is bricked because of incorect flashing procedure or incompatible partitions (flashed by mistake, patched incorectly or flashed partitions with wrong partition numbers. Sometimes TV can brick during original firmware upgrade procedure. Most partitions to restore are: /dev/bml0/4, /dev/bml0/5, /dev/bml0/6, /dev/bml0/7
I didn`t mention u-boot partition (/dev/bml0/2) because if you have it working - you do not need restore it and /dev/bml0/8, /dev/bml0/9, /dev/bml0/10, /dev/bml0/11 - there are samsung firmware partitions.

=== Prepare USB ===
* 1. Format USB to FAT32 [[Image:Uboot_06.png|300px|thumb|right|File structure on USB]]
* 2. Copy required images to /update directory on USB. 
* 3. Extract firmware upgrade file to root of USB. ''Pre Februar'' firmwares you can find [http://wiki.samygo.tv/index.php?title=Old_%26_Good_Firmwares here]. 
* 4. For images or dumps you can ask in forum. 
* 5. List of [http://wiki.samygo.tv/index.php?title=Dumping_and_Flashing_images_by_hand Partitions] = images to use for restoring:
/dev/bml0/1 = '''onboot.bin'''
/dev/bml0/2 = '''u-boot.bin'''
/dev/bml0/3 = '''uboot_env.bin'''
/dev/bml0/4 = '''fnw.bin''' (or '''onw.bin''' for some models)
/dev/bml0/5 = '''Image'''
/dev/bml0/6 = '''rootfs.img'''
/dev/bml0/7 = '''boot.img'''

=== Downloads ===
Here we add links to images for restoring (under construction)
* u-boot.bin, fnw.bin, Image for [http://rapidshare.com/files/433718722/LEB650T5W_bml2_4_5.rar LExxB65x, LExxB75x]
* u-boot.bin, fnw.bin, Image for [http://rapidshare.com/files/433929404/b7000_8000_uboot_fnw_kernel.rar UExxB7xxx, UExxB8xxx]

== Repair procedure ==
=== Get to u-boot prompt ===
* 1. Connect Power & ExLink cable to TV. TV is in stand-by mode. 
* 2. Press [shift + ~], power on TV from RC (remote control) 
[[Image:uboot_02.png|500px|thumb|none|Press any key to enter BOOTROM DEBUG SESSION before timeout. You have 3 sec to do that.]]
* 3. Enter "0" (zero) to get to u-boot prompt (console)
0
[[Image:uboot_05.png|500px|thumb|none|Go to u-boot prompt by pressing 0 and ENTER]]

=== Write images with bbm ===
==== Scan USB for images ====
* 4. Connect USB to TV 
* 5. Enter to u-boot prompt just after LEONID# 
bbm usb
You get this screen:
[[Image:uboot_07.png|500px|thumb|none]]
==== Flashing image to TV ====
* 6. Press number of partition listed to select partition you want to restore.
(Step 6 and 7 show how to restore u-boot partition with file u-boot.bin). We use "1" - u-boot for example.
1
[[Image:uboot_08.png|500px|thumb|none]]
* 7. Enter image name you want to restore selected in step 6 partition and confirm with ENTER. 
u-boot.bin
[[Image:uboot_09.png|500px|thumb|none|Restoring u-boot.bin]]

You can repeat steps 6 and 7 for every partition you want restore (except exe.img and appdata.img - go to Step 10).
Use any of images listed in [[#Prepare_USB|Prepare USB]] if you have it on USB/update directory.
After you finish go to step 8.

* 8. Enter "x" to return to u-boot promt.
x
[[Image:uboot_10.png|500px|thumb|none]]
* 9. Enter "bbm show partition" to check if everything is ok 
(for B6000 numbers in red block must be identical you get. If not - repeat steps again. Other models - info will be later)
bbm show partition
[[Image:uboot_18.png|500px|thumb|none|Partition list on B6000]]

Now you are done. Restart TV and check if it is OK.
If you bricked TV with patched samsung firmware, you need restore firmware files.
=== Restore firmware files ===
If you need restore exe.img and appdata.img, read [http://wiki.samygo.tv/index.php?title=Recovery_of_Bricked_Device manual here].
