How to Fix OnePlus Bootloop issue on Locked Bootloader

In this guide, we will show you the steps to fix the bootloop issue on any OnePlus device having a locked bootloader. Recently, one of my friend’s OnePlus 7T devices all of sudden went into a bootloop. She is one of those users who stays away from custom development. Let alone unlocking the bootloader or flashing custom binaries, she hasn’t even downloaded any third-party icon packs on her device.

Furthermore, while the device has received the first Android 11 open beta, she is still on the Android 10 stable update as she doesn’t wish to take any risk. All this completely makes sense on her end as not everyone wishes to step into this unchartered territory of rooting, installing TWRP, and the likes. However, all this intrigued me even further.

The Never-Ending OnePlus Bootloop!

Since she hasn’t even touched any partition on her device or carried out any modification, how could her OnePlus device go into a bootloop all of a sudden? Well, in my case, these bootloops. soft brick and even hard bricks are nothing new and I occasionally go through these issues as I’m mostly engrossed in the custom development segment.

As a result, if the device ended up in a soft brick or bootloop, there was always the option to flash the stock OxygenOS firmware via Fastboot Commands. Then in the case of hard brick, MSMTool was always there to the rescue (unbrick my OnePlus). However, I couldn’t recommend any such methods to her, not because of the technicalities involved, but just because her device’s bootloader was locked!

So I tried out a few tweaks fortunately, I was able to rectify this issue. Then I thought of sharing the fix with you as well, as it could happen with any one of our’s devices.  So without further ado, here are the detailed instructions to fix the bootloop issue on any OnePlus device having a locked bootloader. Follow along.

How to Fix OnePlus Bootloop issue on Locked Bootloader

First and foremost, the process might wipe off all the data on your device. And since your device is in a bootloop, there might not be any way of taking a backup. So if that’s well and good (after all a fully working device > data), then follow along with the steps.

  1. With your device currently in a bootloop, press and hold the Volume Up, Volume Down, and Power keys for a few seconds.
  2. Doing so will boot your device to the Fastboot mode, as shown below.
  3. As of now, you should see the green Start keyword written at the top menu (see above image).
  4. So press the Volume Down button to bring the Recovery Mode option. Then press the Power key to confirm it.
