Unlocking bootloader

I know unlocking bootloader wipes the phone's data for security reasons.
Just curious, does it deletes the data(deletes the address to the memory location) OR
formats it(overwrites the content - cannot be retrieved)?

Unlocking the bootloader with 'fastboot flashing unlock' (which is only possible after enabling the "Allow OEM unlocking" toggle in Developer Options) reformats the entire user-writable file system rather than simply erasing the individual files. You will not be able to recover any data after performing the required wipe.

Just enabling the toggle doesn't unlock the bootloader or wipe the device; you must still reboot to the bootloader and issue the appropriate 'fastboot' command.

Hopefully that helps to answer the original question, but please let us know if you need additional clarification.

Cheers,

Howdy do
 
No; it does none of that. It simply allows the user to write changes to the OS, via a cable to a desktop running the "adb" package. It is used for updating, changing, or making repairs.

Is it so? Because the steps on the internet to root your phone says the first step is to unlock the bootloader. and when unlocking the bootloader, the phone's memory gets wiped off.

Hi shsocal282426 nil,
 
I replied to your post on the Android Community too. Unlocking the bootloader does wipe the device. See this link - https://developers.google.com/android/images. It's the official page for Pixel and Nexus factory images.
 
Rooting just involves flashing a zip file to your phone after unlocking the bootloader and maybe installing a custom recovery. It doesn't wipe your phone, but since unlocking the bootloader is a prerequisite for rooting, the phone does get wiped as part of the whole process.
 
If you're still after getting your files back as you stated in the other community, I would suggest you to not take the risk of rooting your phone just because of that. We don't support rooted phones here, so if you're stuck anywhere during the process or if you damage your phone, forums like XDA will be the only place you could get help.

I do not agree. In DEVELOPER OPTIONS, flipping the OEM unlocking on ["Allow the bootloader to be unlocked"] DOES NOT wipe the phone. At all.
Never did, any OS release. [I am on Android 10].

That's correct. Flipping the switch in developer options doesn't wipe the device; it doesn't unlock the bootloader either. It just allows you to do so if you wish to.

Unlocking the bootloader consists of actually running the command "fastboot flashing unlock" or "fastboot oem unlock" (whichever is applicable) after booting the device into fastboot mode and connecting it to a PC.
