well it's not like we don't have them it'that they are locked down tighter than fort knox
also I've been trying to get reboot to download mode working but no luck
I'll see if I still have an apk for an experimental Samsung s3 reboot app that the dev was able to boot directly into dl mode via the app. Think there would be a similarity?

Unfortunately twrp 2.6.3.3 or 2.7.0.0 cannot handle device encryption on gpad. After I encrypted my device and booted into twrp, there is not data partition. On my Nexus 4 I get a password prompt and then it mounts the data partition. On Gpad I cannot even tick the data partition in Mount-Options and I don't get a password prompt.

yeah I never did anything with encryption so it probably isn't going to work
your the first person to ever mention anything about it so I just left it alone but I can look into making it work.

Thanks for trying to fix it, I am looking forward to act as guinea pig.

Maybe one of these flags fixes encryption:

TW_INCLUDE_CRYPTO := true
TW_INCLUDE_JB_CRYPTO := true
I think I need these too
but finding the hex for FS_FLAGS is key I think
but I'm not sure cause I keep getting error can't locate footer

TW_CRYPTO_FS_FLAGS := "0x00000406"
TW_CRYPTO_KEY_LOC := "footer"

I built TWRP with encryption and don't have that error in the log. Anyway my data partition is not encrypted, so I cannot test it properly.

Thanks! I tried your build and everything seems to work. When booting into twrp I get a password prompt and then my data partition is mounted successfully. I did a test backup without errors.

EDIT:
I tried to wipe the already mounted data partiotion to remove encryption. First it wipes data, but not completely, because it says: "data cannot be mounted". I cannot restore to this partiition. I then flashed older twrp and removed the encryption by wiping Data. Now I was able to restore my backup with your build. So mounting encypted data and backup/restore work with your build, but wiping data (to remove encryption) fails. Testet on cm11 rom.

EDIT2:
Some more feedback: Today I tried leaked lg stock rom 4.4.2 from this thread. I enabled device encryption in stock rom and after that twrp was not able to mount data partition. So it seems that lg modified something in the encryption process. If I enable device encryption in cm11, then I am able to backup and restore with your build.
