Upgrade From ICS4.0 bootloader to JB4.3 bootloader in an OTA

[Dave S]

Does anyone know how to get the bootloader to upgrade with the rest of the Android system in an OTA? I know the bootloader does not write to its own partion and needs to be upgraded to to get JB4.3. The contents of an OTA contain:
MEAT-INF folder
recovery folder
system folder
boot.img
file_contexts
Would I insert the u-boot.bin into this and zip it? Is there a script? I could go into an ADB shell and type:

Code:

# sudo dd if=u-boot-no-padding.bin of=/dev/sdx bs=1K seek=1; sync

but I would rather try to do it in an OTA. 

Please help.
Thank-you

I cannot answer the question exactly but perhaps the file at /device/asus/grouper/releasetools.py might be useful for you. It contains some instructions that add bootloader image to OTA package.

As far as I understand this script is used by release tools due to TARGET_RELEASETOOLS_EXTENSIONS variable set in  /device/asus/grouper/BoardConfig.mk

Please let us know it you find the solution :)
