PC somehow got linked to Android and after rest both devices are corrupted

[Sarahmw333]

I have been trying to figure out how this happened all night and am going on no sleep so I apologize if I'm not very clear. So, I noticed that my first my PC, then my phone (Samsung Galaxy s8 plus) were acting funny and then seemed to be responding to input from remote devices. I panicked and thought someone must have accessed one of my devices, then the other, then did a hard reset/ recovery on both devices. After both devices restarted (after a lot of work), they both looked and behaved very..."not good" for lack of a better phrase. Then I remembered that a few months ago I had installed ADB/ SDK tools and it seemed like my PC and Android had gotten linked via the wireless connection/ router. I believe that is how someone was able to gain access to my PC (however, for all I know or remember, whatever I was pressing on my phone was causing the issues on my PC and vice versa). So, now I have two devices that are basically "functioning"-ish, but still totally f-...messed up. How can I fix this so that they both are more or less "reset" to original, default states/ settings  or at least not interacting strangely and causing a multitude of issues? I can add any log files if that might help but I'm not sure where to even start as far as the "multitude of issues" goes. Thank you in advance for any help!

The Android phone will require a factory reset and will erase everything -- usually using Settings --> System --> Reset.

The PC factory reset can be done the following ways:

- Factory reset using internal HP image
- Factory reset using external HP image you make
- Factory reset using external HP image you buy

Each of these is discussed in some detail below ...

---------- Factory reset using internal HP image ----------
HP preloads most PCs with a compressed Windows Image that can be used to completely restore the PC to its original condition. This image is contained in the Recovery partition, and if it is intact, it will generally work well.

To do this, you press the Esc key repeatedly while rebooting and when the HP Startup Menu appears, you select the option to do the reset -- usually F11. This will take a couple of hours or more to complete and when done, your PC will start over with initial setup screens. That means that EVERYTHING previously on your PC will have been erased: accounts, settings, personal data, applications, drivers.

NOTE that the disk drive has to be in excellent condition or this will fail. So, BEFORE you do this, instead of pressing F11 as above, press F2 to run diagnostics. If the disk test passes, you should be able to run the reset.

---------- Factory reset using external HP image you make ----------
HP provides a Cloud Recovery tool that you can use, together with a 32GB USB stick, to create your on HP reset media.

Here is the link: https://support.hp.com/us-en/document/c06162205

This works the same as the factory reset described above.

---------- Factory reset using external HP image you buy ----------
For those PCs not supported by the Cloud Recovery, in some cases, HP offers Recover Media for sale. This can not be downloaded; instead, it must be ordered from HP.

HP Recovery Media is a set of DVDs and a CD, or USB stick, that will erase the hard drive (removing all data, settings, and applications, reinstall the original OS, drivers, and some HP Utilities.

In some cases, you may be able to order a USB stick instead of disks.

You can look online for Recovery Media starting with the linked paged: http://support.hp.com/us-en/drivers

Once there, input your Product name or number. On your Software and Drivers Download page, select your Operating System and and Version. Click &quot;Update&quot;.<br><br>If HP Recovery Media is available for your machine, down near the bottom of the page, you will see an entry for Order Recovery Media-CD/DVD/USB. Click the &quot;+&quot; symbol to expand that entry and click on Order Media for details.

Or, if you prefer, you can do the same by contacting HP Customer Support.

HP contact info: https://support.hp.com/us-en/contact-hp?openCLC=true

If HP no longer carries the media you need, another site you should check for HP Recovery Media is: http://www.computersurgeons.com/

These work the same as the factory reset described above.

After you get these two devices reset, my own suggestion is to read up on what Win10 does to "synch" devices -- which is what I believe is at the heart of the problem.  I do NOT synch my devices to avoid these issues.
