Hello,
I know that all V20's have encryption turned on by default.
Does that mean doing a simple factory reset is enough to make all data unrecoverable?
I was considering zeroing out the phone, but I'm not going to bother if factory reset is enough.
Thanks!

If you're using a custom recovery like the TWRP fork for our phone, then formatting all the partitions using that and then re-doing the phone using a .kdz via LGUP will be your best bet. Alternatively, I'm quite sure a factory reset will do the trick, since it formats the /data partition and restores the /system to how it came out of the box. Should be more than enough.

Just as an FYI if you run the factory reset, it will ERASE the "32gb internal memory" also.
That is ****ing retarded! So every time I need for wipe for custom ROM I need to back up 32 GB worth of data!?!
Moto - you really ****ed up here again because you did not apply any brains. I now have to factor in 3-4 hours of backup and restore time for every wipe.
Well. "Factory Reset" to me would mean an "Out of the box state" - meaning all yo **** be gone.
My wifes Optimus S wipes the SD card with a factory reset as well. Never done one on my Epic, but I would assume it's the same.
Can I just say... I thought this was obvious.
Any device with built in storage will wipe that storage on a factory reset. Also, right under where it says "Factory data reset" it also says "Erases all data on tablet".
tbh, it's your own fault if you lose data doing this.

This is actually what I expect from a factory reset! I even wish it would not just delete the memory but overwrite it with zeroes or something.
Is this the 'Factory Data Reset' under 'Privacy' that you speak of? If so, does that truly reset everything as if you just got it out of the box? Root/Kernels/everything?
Just asking as I need to do this since I have done something over the course of the Xoom's life that isn't allowing me to flash BRD's kernels as well as CWM isn't working correctly. Might as well start over and if this does that... then great.
I have seen all the stock dumps in the dev section, but honestly just not sure how to do a complete 'back to stock' wipe.
Thanks...
EDIT: Some info from their site: https://motorola-global-en-uk.custhelp.com/app/answers/detail/a_id/64276/~/motorola-xoom-wi-fi---master-reset-%2F-factory-data-reset
Doesn't answer my question on whether it will affect the kernel and/or whether rooting it has any effect. Anyone know?

Its interesting. On my atrix, it leaves all my data and even flashing the sbf. Only wipes the system data and replaces it. Not data. Dont know why the xoom would do it.
So if it sounds right it would delete EVERYTHING on the internal wtf I would need a 64 micro SD for backing up later on
Moto needs to fix this

Got a replacement device for my defective unit and need to return it.
How do I wipe the internal storage safely?
Just doing a factory reset is so fast I don't think this overwrites anything.
I'm not rooted.
Performing a factory reset via the stock recovery will wipe your internal sdcard.

I think you can accomplish the same with the factory reset option in the Settings app. There is an option to wipe your pictures if I can remember. This will wipe the internal SD card to.

Yes but I suppose this only sets some bits in the boot sector and does not actually overwrite data, so it might be recoverable.
Usually to securly wipe data it is overwritten with zeros or anything else.

Oh i see what you mean. You can format each of the internal partitions, and then rewrite all of the stock images. That should thoroughly wipe everything, and make it very hard (if not impossible) to recover anything. Heres a guide: http://forum.xda-developers.com/showthread.php?t=2010312
Needs root thou I suppose...
Hmm seems there is no chance. I mean Google has my data anyway. Just want to be sure they don't fix it and resell it to some guy that is a bit too cursious.

No you dont need root. Read the guide (steps A,C,D)...all you need is an unlocked bootloader, then after youre done you can relock it.
After rooting and getting different ROMs. Something happened and I get all these error messages on different things. It is most likely a corrupt file, but when I factory reset, it is still the same. How do I fix this? I factory reset and didn't even restore anything. I am on basically a new phone. I also still have all my app data though.

You need to do a full wipe, meaning everything (except the sdcard), especially the system.
How are you doing the factory reset btw? If you're doing it via the recovery, you're good to go. After doing the factory reset, go into the advanced wipe section and wipe the system also. If you are using TWRP, you can select system on the first screen after choosing wipe.

Since I don't have cwm installed, I'd be doing you a disservice, but try wiping everything from the recovery and try again. Most roms will wipe system and so forth, but not all of them does a good job of it and end up leaving bits and pieces lying around.

I updated my Nexus 4 to LMY 48T yesterday and noticed that my storage space is all screwed up. The totals of all my storage come to about 5GB total according to all the internal storage added up. So I am somehow missing approx 8GB of storage space that is not accounted for. I downgraded to LMY 48M to see if the new update had a bug. Nothing!! Somehow my phone has burned 8GB of space. How do I get this back to what it is supposed to read.??? I tried wiping the cache partition, no good. I am fresh out of ideas.
This is a common issue you need to reflash the factory images and it will be fixed.

Not only did I reflash the same factory image 3 times I even rolled back to an earlier image. It still says I only have 1 . 2GB of storage space available, but when you total up everything you come to maybe 4 or 5 GB used and there is 8 GB missing. I used Wugs Toolkit to root and flash images. The only thing I haven't done is to do a complete factory reset.

You should really learn the art of SEARCHING. You would have spent less time looking for the answer than you did typing this post!

The art of the search set aside, are you directing me to do a factory reset, period to get my storage space back, because I am trying to avoid a total factory reset at all costs. I was using Wugs Toolkit to flash the updates using the "No Wipe" mode. Maybe it won't work without doing the complete factory reset, but as I said I was trying to get my space back without using the most drastic measures. I booted into recovery and used the cache partition wipe hoping that might work, not to mention using GOOGLE to look up about 25 methods that all said the same thing, some easy some a little more complex, but they all come back to a " Complete Factory Reset" . Anyway, unless I'm not reading your post right thanks for your thoughts.

I linked you there because that is THE option...there is no alternative. Copy your files, run a nandroid and copy it to your computer, then settle in for a factory reset.
I have to do it every single time I flash an Ubuntu or Mozilla rom, and even some factory images. I've been doing it for a LONG TIME...trust me when I tell you this: there is no alternative.
There is one good piece of news, though...when you restore that nandroid your storage will be right, as long as you follow the guide correctly
Also, factory reset from stock recovery isn't 100%....erasing every single partition and reflashing from fastboot is.
Hi. Just got the 60P. I was wondering if I have to backup my files everytime I need to hard reset the phone. I have the 64GB version and it would be a pain. Thanks.
I'm assuming you're talking about the internal storage and that by resetting you mean restore to factory default via settings. Then yes, you'll have to back up your files to a separate location before you reset. The internal storage gets wiped when you do so. You'll also get a warning stating that stuff like photos, videos and apps etc. get wiped.

This comes as a surprise, really. No sense to bother to test roms then. What a pain.
Well, lets clarify this. When I had my gnex with only the internal storage, and would wipe in between roms, I wouldn't loss the files and roms I had downloaded. But would lose everything else like in a normal factory reset. Not sure how or why. Hopefully someone else can chime in. I mean cause what would be the point of creating nandroid backups if they just get deleted every time you wipe and flash a new rom.
Exactly. I had a previous nexus (nexus 3 maybe) and it kept my files.
Yeah so we need some clarification. Cause I'd like to flash some roms to but not if everything just gets deleted, including my roms and backups.
Okay so figured it out. When in twrp and wiping data, just make sure internal storage is not ticked. Then all your backups, roms, and whatever else will remain.
A factory reset will not touch your SD card. If you go in advance wipe in twrp you have the option to check internal storage but it isn't checked by default. If you check this it will wipe everything but there is no need to do this to clean flash ROMs.

This. TWRP leaves /sdcard untouched when you do a Factory Reset. /sdcard is where all of your pics, video, downloaded files reside. This is stated on the TWRP screen above where you swipe to perform a Factory Reset.

Root and twrp it is then! Thanks guys!
Yes In TWRP you have Safe External SD card + Only Device Memory Reset
