How to permanently erase data ? - Huawei Mate 9 Questions & Answers

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...'.

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.

Internal storage space

OK I don't think this is ROM related, but I am running CM11 M11 (I think) but I have had the issue for a while now. My internal SD card only shows about 600mb available. I have literally gone through every file on there and there is no way it is actually being used. Is there any way to format the interval SD card without wiping the entire system? Some how I think the way the system is reading the space is wrong. Because when I go to the storage tab in settings or will show like 10 goods available for about 3 seconds then it shows full. So it really sounds like there is something Hunny somewhere.

Have you tried using SDmaid by Dark3n? It has a find largest files function. For me this problem was produced by either dropbox or box (can't remember which) saving an additional copy of everything I uploaded to my internal storage.

I had this issue. I had to "format data" in TWRP. Be careful, you will lose everything! Make sure you back up all of your data, photos, music etc to PC. I made a fresh backup to external SD, and was able to restore that after, then restore photos, etc from PC.
Good luck.

If your recovery is CWM, did you make any backups?
I tried sdmaid and that did not work or find anything.
Ended up having to format my system and that did fix it. I just really did not want to.
As far as backups, no I have not. As my brother in law states I like living on the edge. That and I don't flash add much add I used to, and only 'stable' releases.

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 recover my photos from my rooted android

Hi i recently made a backup with wondershare mobile trans and it created a .BAK file of 30gb and it is corrupted i don't know why, I can't read videos and photos (if you know any way to access the data in it even if it is corrupted please tell me), i tried extracting it with winrar but it only extracts 6gb of some photos , the rest is corrupted it can't finish extraction.
I flashed a new rom and orange fox recovery , i have root access , i installed disk digger with full root access but it can't find any photo (not a single one) in my internal storage , is there any way to recover my photos from internal storage ?
I flashed my phone before knowing The backup file .BAK was corrupted
If you flash a ROM then Android's internal storage memory - who is surprised ? - gets completely overwritten, means previously stored data have been lost.

I formatted internal storage before flashing the new rom
Steps to recover your deleted data from your rooted Android device-
1. Connect Your Android device.
2. Launch Android Data Recovery software on computer and choose 'Data Recovery'
3. Choose file types to Scan
4. Preview and restore lost data from Android phone.
Stop using your phone to prevent new files from overwriting lost data. Then try to use data recovery software to detect the photos from internal storage. If it can be detected, recovery is simple.

I tend to think it's a lost cause especially if the drive is zeroed out when you flashed.
Don't know but...
This wouldn't surprise me as it's a wise precaution to ensure a clean flash/load.
Even if not overwritten the file structure is lost as that was certainly overwritten when you flashed it. All you will find at best is completely random disjointed files.
The images will have no metadata ie time stamp etc. If you have hundreds, thousands of random images just forgetting about them becomes the less frustrating option many times. There's no way to index them except by memory, one at a time.
Been there, done that

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

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?
Overwrite the complete internal storage space with ZEROS and BLANKS.

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?
