The patches with the 8096_microSOM_820_Android_BSP-M-2.2 release were intended to fix bugs. Some of the 2.2 patches are already incorporated into the 8096_microSOM_820_Android_BSP-N-3.2 release. If you want to modify the aboot, you can use the aboot patch that is used in the 2.2 release and port it over to the 3.2. The aboot has not been changed on the 3.2 release and is the same as 2.2.
Please note that changes to the aboot requires signing. The signing tool used to sign the aboot is proprietary to Qualcomm and is only available to Qualcomm Licensees and therefore, cannot be released to public. Failure to sign the aboot will render your device unusable, so this is not something we recommend you attempt.
If you need our help in signing, please contact firstname.lastname@example.org and we can discuss how we can help you with this process.
