Will wiping system and internal storage of my phone using twrp makes all my data unrecoverable? - General Questions and Answers

Hello, I am planning to sell my phone and I do have some information (like passwords, card, and pin, etc. which I recently captured using my phone camera) and I'm afraid that even I factory reset and overwrite my phone storage by filling it up with files, someone might still be able to recover it. Will wiping system and internal storage of my phone thought twrp makes it unrecoverable?

How will I do that? Is there any tutorial/reference you could suggest? Thank you!

What kind of information can be restored after the factory reset?
Hello, The question is pretty straightforward - is it possible to restore the data on the phone that had existed before the factory reset was made? If I sell my phone on ebay can someone get any glimpse on what has been done with my phone?

Recovering data on hard-reset?

I recently accidentally hard-reset my xda iii. Most of data was stored on my sd card (which of course i can recover). I want to know whether it is possible to recover other data, much in the same way you would with a desktop. There were several important text messages i needed.
Is this possible or has the data gone for good?
Silly me, didn't back up in a while...
in the flash part of the memory you can as in /storage and extented rom but not the ram they work just like ram in your pc == no power no bytes no memory of last state to undelete to
Ok, so there may still be some data in the flash part. Do you know of any programs that might help me?
Thanks for your reply
A hard reset will have more than likely wiped what was stored internally.
I suggest you get a backup utility and start using it, that way, if it happens again, you will have a full backup of everything you had installed, and all of the files stored on the device.

[Q] [HELP] Accidentally formatted data partition

I wanted to do a factory reset (i.e. remove everything from /data except /data/media/0), but ended up formatting the partition, partly because the Materialised Theme rearranges the buttons, partly because I am a bit dumb seemingly...
After I realized what I just did, I immediately piped the whole partition onto my PC using dd and netcat. I hoped to be able to recover my photos and the /data TWRP backup I did before using photorec, but it couldn't find a single file :crying:
So does TWRP reset every bit of the partition to zero when formatting it?
Or could there be another explanation on why photorec doesn't find anything? Could there be any chance that I'll see my data again?
It's flash memory, tricks that would work on a physical hard disk WILL NOT recover any data. I am sorry but it is not possible, by ANY means, to recover your data.
It sucks I know but please take this as a learning experience on the value of off-device backups. You can upload twrp backups to Google drive directly from the phone for easy secure storage and recovery.
Also Google will sync and backup your photos if you enable it, for the future.

downgrade from oreo beta..Formatted phone.. help recover photos

Hello guys, I have a S8+ 955U version tmobile. I was on oreo beta and wanted to revert back to 7.0 latest which is G955USQS2BRB1. I odin the files but it caused me to format my internal memory. i lost all my photos of my newborn.
How can I get them back?
I've tried a few programs but I have to be rooted which I'm not.
I found a thread SAMPWNED to root device but I can't downfrade that far back.
Any help would be appreciated.
P.S. no i did not have an sd card in the phone, all files were saved on internal.
It's really difficult to recover photos from a formatted internal SD card. Best option, I think, would be try some other recovery apps, so see if they have access to your phone, though I don't think they will have that type of low-level access.
Another possibility might be to use ADB and if you can, pre-system/security startup, enable ADB within the phone, and then you might be able to do a recovery scan of the phone partitions.
There are a few (vague?) how to's on using ADB to enter the phone pre-system/security. Search 'sonnettie', the author of one method, and you will likely find other author off-shoots of the same type of method. If I don't stay current with a thing, I forget most of the details, but that was his original(?) method, which as I was told, came to be used by others to get into the phone pre-system startup/security. It might have been obviated by the Oreo update with a bug fix.
Did you have Samsung backup configured? If so it should have uploaded the photos and you would be able to restore them. If you don't make a backup your photos are already lost, you never know when your phone might die, be stolen or in this case get formatted. Google photos is a good alternative to keep your photos backing up.
Some people have incorrectly stated that it is possible to recover the photos after formatting internal storage. The data partition is encrypted by default and unless you are able to recover both, encryption key (it was most likely overwritten during first boot after factory reset) and the part of the partition containing the photos, you cannot get your photos back. Also, I have not seen any commercial data recovery software, which is capable of finding encryption keys and deciphering corrupted data partition.
Exactly, the phone is encrypted, not remotely possible to recover the photos scanning the memory

good to know.
Thanks everyone for your input. After spending countless hours trying to root phone so I could get a data recovery program on it, I gave up. Turns out I had google photos and Samsung cloud turned on and it synced all my media. I got all my media back on my phone.
Thanks guys
@OP
i want to remind you that if you are doing like updating, flashing, modifying, always make a back up thank god samsung cloud is doing that for you., but i always make a hard copy to my sd card always you newer know right. i am happy for you that you got your data back

How to permanently erase data ?

Hi guys, I deleted some videos and photos from my Huawei 9 Mate the normal way before I let go, but I want to be sure that no one can restore it. I also downloaded Shreddit app and I will use it on empty storage space. Are any data still recorevable after this ? I did a little research and found out that Huawei can't be encrypted, so can anyone give me a tip, what to do, so no one could recover any data ? Thanks

You will be fine, are you that concerned? Chances of someone actually digging old information out is NOT LIKELY going to happen unless for some reason the phone lands in the wrong hands and involves authorities
to get clean, you can use this app -> https://play.google.com/store/apps/details?id=com.apparillos.android.androshredder
to get a safer access to your personal files, you can use this app -> https://play.google.com/store/apps/details?id=com.egosecure.uem.encryption
but 100% safeness, seems to be impossible until now. (depending on whoever gets the device in their hands)
Hi, thank you for your tips. I downloaded both apps. I already deleted the files a week ago, so now I just have to wipe the internal storage, but it doesn't give you the option to wipe just empty space. I will have to wipe everything. Is the Andro Shredder better than Shreddit ? With Shreddit you can wipe just internal empty space. The EgoSecure Encryption seems just to encrypt single files, can I encrypt the whole storage before factory reset ? In Huawei there is also function called "safe" when I go to security (I don't have the english version), where you can choose password for the whole internal storage, wouldn't this be enough for encryption ? Thanks
i have no own experience with the Huawei build in encryption.
EgoSecure is also able to encrypt the whole folders if you need.
AndroShredder can cleanup and shredder internal and external SD! Sometimes you have to go to the upper right side to the 3 dots to select "show internal drive too" to be able to have access to both sd cards.
I had tried both apps (androshredder and shreddit). androshredder has won because i can't get access with shreddit to files on external sd! they are shown with a lock symbol.
Go into Recovery Mode, then select 'wipe data...' and 'wipe cache...'.

Can I recover my broken internal storage after a TWRP restore of an earlier sec ver?

I made a newbie mistake today and restored a TWRP backup from an earlier security patch. Now, my interal storage is inaccessible and the filenames are gibberish, as expected.
Is there ANY way possible to recover my internal storage? I never backed it up to another location, and I would really like to get it back.

Yes, remember the version you had installed during the backup and flash that without wiping data, sometimes it's still on your second boot slot. In that case:
Go to twrp, change boot slot, flash twrp.zip (don't wipe data) and reboot
