Likewise, the customization opportunities are also quickly expanding with each new bump in the OneUI version.

Given below are the steps to unlock the bootloader on any Samsung device, keeping in mind the new VaultKeeper security check.

Unlock Bootloader: Benefits and Risks

Unlocking your device’s bootloader is like opening the gate to a plethora of opportunities. You could flash various Custom ROMs, install Custom Recovery (like TWRP), try out tons of mods and hacks, and most importantly- root your device. The latter could be done via TWRP (flashing Magisk ZIP via TWRP) or without TWRP (by patching and flashing the stock boot. img). After you get administrative privileges, you could then try out a ton of Magisk ModulesXposed Framework, Substratum Themes, among others.

However, they do bring in a few uninvited risks as well. To begin with, it will trip the Knox counter of your device. This will straightway make your Samsung device’s warranty null and void. Furthermore, all the apps that depend on this Knox will no longer function. These include the likes of Samsung Pay and Secure Folder. Likewise, apps like Google Pay and Pokeom Go might no longer function. Netlfix Widevine L1 Certification will also be degraded to L3, as a result, you wouldn’t be able to watch videos in HD.

  1. I have a little problem with a Samsung SM-A115W.
    There’s no “OEM Unlock option” in the Developer Options.

    The usual workaround being circulated on the internet is to leave it connected to internet for 7 days and let it do the system update from Samsung or whatever.

    But I don’t want to do that because once it gets the update, there’s no way back, a factory reset will not bring it back to the original firmware at the time of purchase. And a security update might actually remove even the slightest chance of unlocking the bootloader by removing that option from the system.

    This phone has a newer bootloader version (0.5)
    Fastboot fails on most commands, except for “fastboot devices” or “fastboot getvar all”

  2. hi hassan . i have a samsung galaxy sm51f mobile phone. there is no secure folder opiton. do you have any ideas ?
    the systme updated from 2.0 to 2.5 . but still no secure folder opitons..

    i need your help

    1. Hi Kadir, True to my knowledge, it might be due to geo-restrictions. Some regions, such as Nepal and Bangladesh haven’t got the Secure Folder option after the update. Anyways, what’s the status on Play Store and did you tried sideloading the APK?

  3. Sadique,

    Android os update to 11, even after since hit fixes is still causing my drive to have issues with certain apps, namely war Dragons by pocket Gems. I got a new phone with android 10 on it,but it updated to 11 overnight. Will the steps above allow me to revert an LG V60 ThinkQ from android, never should have been rolled out, 11 back to 10? Zero issues with 10, 11 its all over redit, twitter and other social media platforms that Android 11 has some serious connection issues with google play accounts, certain apps functionality, and overall performance issues with 5G connection and wi-fi enabled everything… Please help. Samsung, Google, LG, Verizon, Comcast, and even the specific app developer Pocket Gems have been useless in trying to resolve these issues. Want to make sure if i root my phone,what else do i need to revert back to 10 instead of 11? Want to make sure I do it right.
