I want to recover photos and videos from my device, I made factory reset from recovery so all the data are lost now and I want to recover them and the device is not rooted, is there and way to do that??
its my first holiday photos and videos with my son
You shouldn't have done a reset if you wanted to try and recover data... I write would them off and move on. In the future back up critical data at least twice on electronically isolated hdds.
Yeah, @blackhawk is right. You need to backup beforehand. Doing a factory reset was the end of it, mostly.
Sadly you don't have low-level access to the eMMC memory chip, even with root is hard to get it down right, so there is no recovery of lost data available to you.
If that data was extremely precious to you your only option would be a data recovery center (which would try to read the data pages right off the chip itself externaly) but that means you should not use the device in order to ovoid overwrites of the pages and trim triggers.

People smash their screens or otherwise total their phones too but they are in a better position if they're willing to go to extremes.
Something like this:

With an intact phone the cost should be lower but as you pointed out still very problematic.
The file system was destroyed by the reset so any recovered data be bits and pieces that are juxtaposed like a huge broken jigsaw puzzle.
Jpegs be intact but all related metadata like pic #, time stamps etc be lost... if they haven't already been overwritten.
I've used recovery software and what you recover is a huge brain numbing mess. Even sorting out a 100 images from a flashcard is a chore let alone a whole phone worth of data.

I was looking around here and found a few ways to "wipe" my phone clean and put on a different ROM. ( http://forum.xda-developers.com/showthread.php?t=439358 )
However would something (as the link above) be enough to remove previous text messages from the internal memory or other sensitive data so someone couldn't easily or at all recover any of my personal information.
(my phone numbers are stored on the SIM, so I don't think my phone book/contacts should be an issue, but I'm more concerned about text messages than anything else.
Besides "wiping" is there anything specific that you would recommend me doing to the phone to "prepare" it for someone else?
Just hard reset, and hang on to any external media (microsd card)... problem solved. Anything else is just a waste of time.
How would anything else be a waste of time? If someone could easily run a "recovery" software on my phone and recover everything I think it would be worth the time and effort.
Basically I don't want to end up in the situation like people have with selling their laptops on ebay (where someone has recovered the entire drive).
Simply put, if the peace of mind knowing that your sensitive data is 100% safe is worth more than the value of the phone, don't sell it
Aside from re-flashing the ROM, I'm not sure that much else can be done.

Hard reset or flashing a rom will wipe any info from your phone. I personally don't have that much "vital" information on my phone, since phones are very susceptible to get lost, broke or stolen

Because... simply put... they can't recover the data once you hard reset. It's flash chips inside not a hard drive. Just don't be stupid and re-sync your phone afterwards and it's fine for sale. And like I said before, hang onto the extra memory cards, because the data on those CAN be recovered, and you don't want all those nude photos of yourself in Barbados getting put on the web now do you.
i got my xperia z about a week ago i absolutely loved it no other phone has had the effect this one has on me i adore it i set it up with my settings apps etc
then i noticed a tiny tiny little scratch and now i want to return it even paying to get it exchanged
however i put in all my passwords in it (which i plan to change)
i did some searching around and saw that encrypting the phone would make the data virtually impossible to recover once deleted
i also used a program called nuke my phone which turns out dosn't work on encrypted files so it was stuck in a loop according to the author of the program encrypting the files before erasing everything has the same effect
so can i now safely change this phone without worrying about anything?
i encrypted the phone which wook about 1 hour i then did a factory reset of it

Are you still playing with this problem ?
It's ok - everyone has looked at porn. We won't judge you. :laugh:
If you have encrypted and factory reset your phone all you can do is check your accounts in settings make sure nothing is there. As a last resort you could format the SD card, obviously take out your own SD card. If you are really in doubt you could fill the internal card with files full of 1 and 0's (overwriting blank space) after that there's nothing much you can do apart from burning the device. Or develop a small EMP to wipe it...
And if you're really paranoid, change all your passwords on your accounts and use 2 step authentication.

you'd think i did but i didn't honest lol
thing is i am paranoid all i want gone is my passwords thats all i never put ANY files in the phone itself i never used the camera i barely got time to use it
i have no sd card in it
as for 2 step verification already activated on all accounts
I'd say you're good so. There is nothing else you can do.

Yep pretty much, good luck to anyone trying to recover that.

Excuse my ignorance but I have always thought that with the built-in factory data reset that...well...that was that and all traces of user info banished.

This is a bad week. Yesterday I dropped my Xperia Z onto the pavement, and it got a major damage at the polyamid frame on the upper right corner. It could have benn worse. no display or back glass broken. Oh, and the cover for the headset plug has to be replaced, too. See the sad picture attached. Repair will cost about 112 Euros (and I think another 100 Euros for spare parts) Today my SanDisk 32GB micro SDHC died from one second to another. Completely dead. It's not even recognized anymore, regardless in which PC or Android Device I put it in.
However, enough self-pity, my question is: How do I secure my whole phone from curious repair-workers? My smartphone is essentially full of sensible and private Data. Emails, Texts, Photos, all the Apps with stored Logins (Facebook and the likes).
My first idea is the Android built-in Encryption under Settings > Security > Encrypt Phone. I've never done that, because it says it takes a whole hour, and there is no information about this encryption can be reverted. Because maybe some App stops working, or it makes the whole phone slow. And now the most important question: Is it worth the effort? Is it really secure facing an autorized sony repair staff member?
Secondly I came up with the thougt of doing a backup. Maybe the Repairman calls me and says he has to do a full service test to ensure every internal bit an piece is still working after repair. Which might mean he has to have access to the phone (and the service menu). Since I have encrypted and locked my phone, this can only be done via factory reset. So I should have an complete backup. Has anyone ever tried the built in backup and restore? Does it really backup everything? Every App, evry Data, every setting (widgets and stuff), well plain and simple - a copy of my phone current state? At the moment it only offers me to backup system files and data, might be due to the fact that there is no sd-card and the internal memory has not enough space.
Any other backupsolutions? My phone is not rooted, and rather shouldn't be (warranty issues)

There you go.
But anyways, I'd say root your phone install cwm and do a nandroid backup. Save the backup file(s) somewhere else (not on your phone duh). Then do a factory reset and send the phone like that.

I wasn't sure if my question concerning encryption is right in the Troubleshooting forums. But if so, maybe an admin can move the thread?
According to your answer I assume the aformentioned stock backup solution isn't that useful at all?
What's with the encryption security?
With my upgrade to the GS4, I now have a Bionic that is gathering dust. If I were to sell it, is there a way I can completely erase it, so that sensitive data cannot be recovered down the road? I.E. something more robust than a plain FDR?
Thank you!
I've never heard of someone recovering info after a factory data reset... I'm sure it's probably possible, given enough time/desire.
If is that important you could always write over sensitive info with fake/junk before wiping.
There may be encryption programs to do this on phone, but not familiar with one.
Just my take on it.
Just a general example of zero-ing out a disk. Rewrites and fills the disk with zeros to make sure all previous data is overwritten.
dd if=/dev/zero of=/dev/sda bs=1M
You could mount your internal and external sd cards and zero them out, just point of= to the partition number, ie of=/dev/sdb1
Not too sure about zero-ing the app data partition. Should be possible, and no problem since it's rebuilt on a rom flash.. I just haven't dabbled there myself.
For security reasons, you should instead fill the partitions with /dev/urandom but this takes longer, and is usually only for the extreme paranoid/experts
ps. I've read that this may cause quite a lot of write cycles on the storage, which kills flash memory.

Any advice/suggestions would be MUCH appreciated!
My problem ultimately stems from the fact that my keyboard has somehow been disabled by some errant app, most likely Google's Tap-to-Talk function, a little over a week ago now. Literally out of nowhere. I disabled the general Google App the very day the tap-to-talk function started overriding the HTC Sense keyboard everywhere, and then noticed that neither the keyboard nor the tap-to-talk function were working. I just thought that I could simply restart my phone and any glitch would be removed and my keyboard would return to its normal functioning. I was completely wrong; I haven't been able to use my phone ever since, simply because the keyboard does not come up as usual for me to enter my password, so that since then I've been completely locked out, even though the phone itself is in working order. As far as I know, I don't think that there's any way of overriding the password entry function so that I could simply get into my phone to try to fix the problem that way--but if there is any way, PLEASE LET ME KNOW.
Anyway, I have already chatted with a tech from Google Play, and when I saw that nothing worked out down that avenue, I talked with two different HTC support techs. I explained my problem to the last one and said that I would like to perform a Wipe Cache Partition, but as soon as she found out that my phone is Unlocked with S-ON, she said that there's a 50/50 chance my phone could become bricked from performing the cache wipe. She did say that it's all relative to the case, and for some, everything works out fine, while for others, not so much, so she went ahead and created a ticket for me to speak later with the higher-level HTC Developer techs. I have also already visited an actual tech place only to discover that the 2 guys working there primarily specialize in hardware and are unwilling to try any software-related fixes, because of liability issues and probably also because they just haven't got a clue.
My primary concern is losing all the data still stored on my phone, because it is still in working order, and so I feel like I have much more of a chance of somehow retrieving it NOW than if I were to proceed with the cache wipe, have it brick on me, and then be forced to figure something out with a completely broken phone.
So the main question is whether it really is that risky for me to perform a wipe cache partition, because after researching it all over the Internet, I came to the conclusion that it is a safe procedure that should not damage any personal files or information. Now I have found out that is not the case for unlocked phones, which all those tutorial articles fail to mention.
Please, if anyone knows, PLEASE tell me if it would be safe for me to perform this cache wipe on my unlocked phone. But also, if you just have ANY relevant advice to share on this general matter, please let me know.
I have already perused a pretty large quantity of sources all over the net and am growing increasingly worried at the lack of options to get my phone back into working order for me to actually be able to use it again. I decided to turn to this site's forum as a kind of near-last resort, because I am growing pretty panicked and desperate.

Wow :laugh:
Wiping the cache partition will only wipe...... the cache partition (/cache) and it will be repopulated at the next reboot. There is no reason why your phone shouldn't boot after clearing the cache. There are always some risk but its far from 50% imo.

You've said that your bootloader is already unlocked right? What about booting in a custom recovery and use ADB to pull all your important files to your computer? Or even better if you have a recent TWRP version, you'll see your phone storage from your computer and you'll be able to simply drag and drop your files to your computer.
