Root [MetroPCS] SD card Hack to increase Internal Memory

Will this hack work with encryption turned on? It popped into my mind that lock screens can be bypassed, i.e. pulling the card out, factory resetting, installing the hack, and putting it back in to get full access. Is this even possible? Not so much an issue on the FAT32 partition, but I believe it's the EXT4 part that contains texts, emails, login info...
 
Right now I don't think this hack would work with full disk encryption. I feel this is a problem I'll have to tackle eventually because Lollipop uses it by default. According to http://www.anandtech.com/show/8725/encryption-and-storage-performance-in-android-50-lollipop , a major problem with using full disk encryption to protect your user data is performance though. So I'm not sure how many users actually want that. But if enough people want it sooner rather than later, let me know and I'll try to do my best to come up with a solution.

All those files are for KitKat. I do not know if they work with Jelly Bean but I have the JB ones. I don't have the uninstall files though. And MiniTool Partition Wizard works wonderfully for me.

I'm planning to flash this hack soon. . So this post above contains the files for Jellybean stock rom?
That other pair of zip files will brick my phone?

An unexprected random crash, and when the phone rebooted, the sd-ext went missing. (Luckily the original /data was still preserved, so phone was still functional, albiet with minimal set of apps).
Upon inspecting the sdcard on my Linux machine, it complained of corrupt ext4 journal entires. Running fsck a couple of times fixed the card, and android was able to mount the sd-ext correctly this time around. But all my accounts are missing now, I have to add them one by one. Oy Ve!

I posted elsewhere that my sd-ext doesn't mount does not mount sometimes, and i'm not using this sd hack. I'm using link2sd. It gives me "no csi structure" error.

I'm wondering why we're getting these errors so easily. They seem so random, or perhaps some app update broke it.

I'm not exactly sure, but I think the last time my sdext failed to mount was when I updated the superSU binary after superSU nagged me about it.

To me it happens with random power loss. Not when shut down or reboots, only power loss.

Like someone else pointed out, on random crashes, the OS doesn't tie up the loose ends with the filesystem so it is corrupted. ext4 is supposed to be resilient to such filesystem corruptions, wonder why it doesn't help here.

it seems formatting the 2nd partition as fat32 is more reliable for me.
dunno if fat32 will have any performance downside though

IIRC, fat32 doesn't support file access permissions, that Android requires, especially for /data.
 
@ksjd0414 bro... On kk.mini. i get to rewrite all data to external binding. Data/media but cant mout external to the internal... (All goes tru excp mount shouldvi use busybox to do it
