Factory reset – How to erase the S7 Edge data when the display is broken

I want to sell the remains of my broken S7 Edge, but before I want to erase all the data. The phone was dead for over a year and I was hoping the repairs would become cheaper, but I finally realized that it would cost me a lot less money to buy cheap smartphones (because I break them very fast, old times where you could crush your phone several times a week on the ground and it would still work for years again: – /)
The device is already open, the glass, the back cover and the screen are already removed.

I've already discovered findmymobile.samsung.com on which I've set a factory reset, but this will only happen when the phone will be connected to a network.
Problem: it does not connect if I put my unlocked SIM card there …

I do not think I can use the android device manager because it does not show up. Do not remember if I had recorded it there.

  • USB debugging is disabled
  • The phone is not rooted
  • the display is completely removed
  • physical pimples are sensitive

I can not really know what state it is in when, but it can be turned on and stay in place long enough.

I've installed adb on my linux, but the device is not listed.
-> How to make it appear?

I'm even considering a physical removal of the hard drive, but I do not know where it is and if that makes the device completely useless.

Fixing the display is not an option.

Will a disk erase be saved?

I see that the disk utility has a "log" button that I currently can not use My questions are:

  1. Can the erasure be seen from the operating system on the disk?
  2. Can the newspaper see it?

Erase Type Rust – Code Review Stack Exchange

This is a very small version of a cryptography library that I write. There are cryptographic algorithms such as RSA, DSA, ECDSA, EdDSA, … that all have the same schema: have a private key, a public key, a signature and operations such as signing data with a private key that gives a signature signature result with a public key that gives a bool result.

There are 3 contradictory requirements:

  • Library integrators should be able to implement generic algorithms over safe type library types and use only 1 crypto types.
  • Each cryptography must have its own family of types. When the user tries to verify an RSA signature with an EdDSA public key, he should receive an error explaining that he has mixed different cryptos (so I need type security).
  • The library must be able to deserialize the entries and for example create a strongly typed EdDSA public key without knowing in advance that the entry will belong to the EdDSA type family.

In production, I have declarative macros for erasing and reifying types in order to avoid duplicates. Is there another way to do this in Rust 1.32.0?

el capitan – trying to erase external SSDs visible only in terminal mode

I have an SSD drive that has been removed from a MacAir and placed in an eclipse. I must have screwed up the directory by deleting files from the drive and not disassembling it because the drive is invisible in DiskUtil. I can see it in Terminal, but when I try to erase the drive with the help of diskutil, it starts up and reaches 30%, and then stops with the message. error below. The player has been saved, so I want to start all over again. The reader was in JHFS + format. Help?

partition – Disk Utility does not erase the external drive

The other night I was working with my 6 month old MacBook Pro and a 6 month external drive connected. I moved to my seat and the external drive slipped and abruptly disconnected from the port. When I reconnected, he asked to initialize, ignore or eject. After some research, I determined that the directory had been messed up by the disconnection. I could either pay to recover the data, or initialize and reapply all the data. I chose to boot.

During the process, the external drive appears only in the Disk Utility. I have tried to remove the disk utility and the terminal, but the error persists: "I can not write the last block of the device". In Disk Utility, the partition option is grayed out and even though the view shows all devices, Passport does not display a partition. When I try to click the eject button in Disk Utility, nothing ever happens.

How can I erase this external drive for reuse?

Copying files from my local drive to Google Drive through Windows Explorer uses the local disk space to make the copy. How can I erase this temporary data?

I'm using a Windows 10 PC. One way to copy files to Google Drive is to use Windows Explorer. I can copy or drag files from my local hard drive to Google Drive accessible through Windows Explorer. Copying files to Drive in this way is fast, certainly much faster than downloading them directly to Drive via Chrome. When I copy a file through Windows Explorer, the process controls this storage space on my local drive, but when the copy is complete, that storage space is not automatically released. From what I understand, this copy of local storage is supposed to erase automatically, but I have not seen it and I do not know in which conditions or what events it is supposed to wipe off. So, if I copy more than 20 gigs on Drive, my C: disc will have 20 fewer gigs, even after the copy is done. Of course, I have the original 20GB files on my drive, and now 20GB on Google Drive, but how can I erase those 20GB of copy data on my local drive? I tried to defrag, but it did not do anything. Thank you.

Android versions – My 6edge is 32gb. I've used about 13 GB, but in the storage option, it shows that 31 GB is used … where is my memory rest. Please erase

applications – Can not erase application data


  • Samsung Galaxy S8
  • Android 8.0 Oreo
  • Application based on this Google example that works correctly on other Galaxy S8 phones


By trying to start from scratch on my application installed by the APK file, I am unable to delete the data from the application.

  • Hit the "Clear data" button in the application settings
  • Operation adb shell pm clear com.myappsname
  • And uninstall / reinstall

Still leaves 16.38KB in the Application Storage Data category.

All I can understand is that this is what is causing the application to malfunction on this particular phone, since it is correctly installed on other S8s. Looking at logcat, I can not really diagnose anything that is wrong with the way apps work, other than the fact that it's not up to date to update the location.

How to completely erase the data from the application (it remains 16.38 kb)?

Thanks in advance!
