[Xoom General] hatxtrick:
Hattrick’s walkthrough to unbricking you Xoom when SBF’ing HLK75D:

Material you need:

1: Bricked Xoom

2: std. USB micro cable

3: Latest USB drivers from MotoDev 32bit/64bit (http://developer.motorola.com/docstools/USB_Drivers/ )

4: Fastboot.exe (this can be downloaded from http://android-roms.googlecode.com/files/fastboot-win32.zip )

5: 3 files out of the Android SDK tool’s folder: (these are not required for this to work, it just good to have these around)

adb.exe

AdbWinApi.dll

AdbWinUsbApi.dll

6: new HLK75D sbf file from motodev http://developer.motorola.com/produ...pportforums&utm_term=unlockboard&pubid=987654

File Name: VZW_MZ602_signed_HLK75D_signed_MDM6600_03.1A.54_signed_LTEDC_U_05.19.00.combo.sbf.gz

7: RSDLite 5.4.4

Steps:

1: Create a folder on your desktop (name it whatever you want) and move the fastboot & all adb files into it.

2: install/verify you system has the latest USB drives installed

3: install RSDLite 5.4.4

4: Extract the. sbf using winrar/gzip/etc.. From the .gz file you downloaded from the MotoDev

5: open notepad or whatever text editor you like & copy & paste the below text:

fastboot oem unlock

Pause

fastboot erase boot

fastboot erase recovery

fastboot erase system

fastboot –w

fastboot oem lock

•	The pause in the script, will allow you time enough to follow the on device instructions to unlock your device. It will reboot as soon as it is finished unlocking

You will need to hold down the volume down key to put it back into fastboot mode after the first reboot

6: Save the text file as a foo.bat and place into the folder with fastboot

7: Reboot your xoom - this can be done by pressing the up volume key and power at the same time.

8: Immediately press and hold the down volume key – this will put the device in fastboot mode.

9: Connect your xoom to your computer via usb cable

10: From the folder where you put the fastboot and the foo.bat, execute the batch file

11: Wait for the unlock/erase/relock process to complete

12: Once the device reboots after the relock it will go into RSD mode immediately

13: Fire up RSDLite 5.4.4 and launch/load the HLK75D SBF

•	Your device will reboot twice during this process

•	This may take up 15 minutes to complete

•	You can leave the 4G LTE sim in the device

14: Once you have complete the flash, the device will reboot and load up Android 3.2.2

15: let the device sit at welcome screen for 5 to 10 minutes, a prompt will appear asking to use the LTE/CDMA network > click yes.

16 Follow on device instructions to setup your device & reconnect to Google.

That’s it!!!! I’ve done this 3 times today and have had zero problems on each reload.

1: I keep seeing posts from people attempting to flash the old 139 image/sbf or using the everest.sbf, there is no need to go back to move forward and I think they are exacerbating the problem.

The everest sbf was used to trigger the original bootloader into RSD mode to allow you to be able to load the HR139 sbf. There is nothing to gain from using it.

2: I keep seeing people posting that their device is now stuck at the boot up Motorola logo: Ok that problem has been covered in this and other posts on XDA, however:

Your device got a bad chunk of something during the flash, be it from a corrupt image, you did not complete a step, or whatever.

Your device is not stuck: try unplugging/re-plugging the usb cable from the device. You will probably notice your computer will make a noise and show that a device has been connected.

This has happened to me, and it is a fairly freaky moment as you think you’ve just bricked a $500 device and that it’s probably not going to be covered under the TOS of the warranty.

For some reason, if, when flashing the device, you have a bad sbf or img file it will upchuck into this mode (it’s fastboot mode) without any writing to indicate that.

Run the foo.bat file again, more than likely you will see the unlock on device information pop up. Then just simply follow the listed above steps.

Cheers,

Hat
