In this tutorial, we will show you the steps to unlock the bootloader on your Realme Narzo 50A (model RMX3430) as well as relock it later on. Realme Narzo 50A was launched in India with a MediaTek Helio G85 processor and triple rear cameras.
There’s a plethora of tweaks, modifications, and custom binaries available for various Realme devices, and the Realme Narzo 50A is no different either. Although it has only been only a couple of months since its launch, we are already seeing impressive support for this device. But to carry out these tweaks, there is just one requirement that needs to be met- your Realme Narzo 50A should have an unlocked bootloader. In this guide, we will help you with just that. Likewise, we will also show you how to relock the device’s bootloader, if you wish to do so at a later stage. Follow along.
Realme Narzo 50A comes with two colour options and they are Oxygen Blue, Oxygen Green. It has been designed especially for those who don’t like charging again and again and so it offers users a 6000mah battery with 18W fast charging support.
A 50MP triple camera is provided on the rear. However, the 8MP front camera is not as good as it needs to be. This is because the users in the present time pay a ton of attention when it comes to selfies.
A dedicated SD card slot is provided for those who simply want to extend storage space. Realme offers two options when it comes to default storage (64 and 128GB). Both variants come with 4GB RAM to make sure the users can have the best performance in all the tasks. Powered by Android 11 based Realme UI 2.0, the users can simply make sure to access all the latest features.
The 6.5 inches IPS LCD is simply capable to let uses enjoy 720 x 1600 pixels resolution. Another good thing about this gadget is it offers users the option for reverse charging. That’s all about specifications. Let’s check now how to fix common problems in Realme Narzo 50A.
