Root [Virgin Mobile] Help with MK5 OTA Update Zip Modification

[ASJ80]

Eventually I want to install CyanogenMod, but for now I decided I wanted to play around with the 4.3 OTA as a learning experience.

Anyway, I'm trying to modify the OTA update so that when I flash it, it doesn't install Knox.

My phone is rooted stock MG2 and I'm using Philz Recovery.

So far I've modified the updater-script file with these changes.
- Added this line "set_perm(0, 0, 06755, "/system/xbin/su");" after the line where xbin has its permissions set
- Removed the lines where is was patching SSuggest.apk with KLMSAgent.apk
- Removed the line where it was renaming SSuggest.apk to KLMSAgent.apk
- Added a line to delete "/system/app/SSuggest.apk"
- Removed the lines that extract aboot.mbn to /dev/block/mmcblk0p5
- Removed the lines that extract sbl2.mbn to /dev/block/mmcblk0p3
- Removed the lines that extract sbl3.mbn to /dev/block/mmcblk0p4
- Modified the lines that are deleting "recovery-from-boot.p" and "install-recovery.sh" to delete "recovery-from-boot.p.bak" and "install-recovery.sh.bak" instead since mine were renamed to that.


This is what I've done to the zip file.
- deleted aboot.mbn
- deleted sbl2.mbn
- deleted sbl3.mbn
- renamed /recovery/recovery-from-boot.p" to /recovery/recovery-from-boot.p.bak
- renamed "/recovery/etc/install-recovery.sh" to "/recovery/etc/install-recovery.sh.bak"
- deleted KLMSAgent.odex
- deleted KNOXAgent.apk and KNOXAgent.odex
- deleted KnoxAttestationAgent.apk and KnoxAttestationAgent.odex
- deleted KNOXStore.apk and KNOXStore.odex
- deleted ContainerAgent.apk and ContainerAgent.odex
- deleted ContainerEventsRelayManager.apk and ContainerEventsRelayManager.odex

My questions are:
Is it safe to let it extract "tz.mbn" to "/dev/block/mmcblk0p8"?
Is it safe to let it extract "rpm.mbn" to "/dev/block/mmcblk0p6"?
Should I worry about mmcblk0p7 being patched with "boot.img.p"?
Should I not have removed sbl2.mbn and sbl3.mbn?
Are the above files in any way part of Knox?

Is there anything else I need to do to the zip file before I can flash it from the Custom Recovery?

You should holler at @jdsingle76 to see what he did when creating his stock/rooted/Knox-free version. He is definitely going to be the most knowledgeable forum member for this topic.

Thanks for the reply.

After further research, I've found out that there are some more files in the zip that I didn't remove that are related to Knox.

Under /system/app/ there are:
- SPDClient.apk

Under /system/containers/framework/ there are:
- KNOXModeSwitcher.apk
- sec_container_1.zzzKnoxLauncher.apk

The .odex file for SPDClient gets created by patching and renaming SlideShow.odex in updater-script.

Anyway, I've removed the above files and references to SPDClient in updater-script.

Also, from various other reading I've done, it looks like I definitely need to keep tz.mbn is I want my wifi to work when the modem gets flashed. rpm.mbn I think is safe as well since from what I've read, it just has to do with power management.

I'm pretty confident now that deleting sbl2.mbn and sbl3.mbn was a good idea.

So I guess now the only things I'm not sure of is patching with boot.img.p and whether or not there is anything else I need to do to the ota zip to make it flashable in custom recovery.

Edit: A few more files I've removed from the zip file
- /system/tima_measurement_info
- /system/lib/libknoxdrawglfunction.so
- /system/etc/secure_storage/com.sec.knox.store/ss_id
