However, the real danger is when you end up with your device in a hard-bricked state. When that happens, forget about TWRP, you can’t even access fastboot mode. This nullifies all the possible solutions, except for one. And in this guide, we will be sharing just this tip. With the help of the given instructions, you could now easily unbrick your OnePlus 7T and bring it back from the dead state. So without further ado, let’s check out the steps. Apart from that, you could also replace your stock recovery with a custom recovery like TWRP. The benefits of this are aplenty. For example, you could create a Nandroid backup, flash ZIP and IMG files, use the MTP features, etc. Likewise, you could also get access to your system partition by rooting your device. Well, we could go on and on listing the benefits. However, things are as simple as it looks. All these practices come with associated risks as well. The thing is since you are into the custom development scene, you already have an idea or two about how to get back your device into normal working conditions. Most of you might be aware of the fact that the best escape route involves booting your device to fastboot and then simply flashing the stock firmware. However, this trick only works when your device is in a bootloop or a soft-bricked state.
The good thing is most often than not, this fastboot-flash escape route works pretty well. But not always! If your device gets hard-bricked, then you wouldn’t be even able to flash the stocks firmware at that point in time. The reason? If your device is bricked then you can’t even boot your device to fastboot. Nor you could boot your device to TWRP recovery and flash any other custom ROM. So what could be done in such a case? Sometimes, you might also get this scary message that Your device is corrupt. It cannot be trusted and will not boot. Don’t worry, we will help you in getting this trust back!
Most of the users at this point in time just rushes to the nearby OnePlus service center. The thing is: what these developers do at the service center, you could do the same at your home as well. And the entire process is only software-related, we wouldn’ be tweaking any of the hardware parts. With that said, here are the complete instructions to Unbrick OnePlus 7T from a dead state. Let’s begin.
How to Unbrick Your OnePlus 7T Device from Dead State
All the Qualcomm based devices come with a special boot mode controlled by the primary bootloader, dubbed as Emergency Download (EDL). OEMs generally bake this mode deep into the device, not accessible from even the tech geeks. One method to access this is via the Test Point method (which involves forcibly opening the back of your device and playing with one or two copper wires). But in that process, there are tons of things involved, most of which are quite dangerous even from our point of view. And hey, we also promised that we wouldn’t be taking the hardware route. So the next and much easier method involves the use of the EDL Mode. Today we will make full use of this mode to unbrick your OnePlus 7T device from a dead state. So without further ado, let’s begin with the guide.
Prerequisites
Before we begin with the process, here are a few points to be kept in mind. Well, we always begin by telling you to create a backup of your entire device, but in this case, that’s completely useless. Similarly, you can’t even enable USB Debugging as well. So the only requirement that we would suggest to you is that your device should be at least 60% charged. Since the device is in a bricked state and you wouldn’t be able to get a clue regarding the battery percentage, it is better to connect your device to a charger and wait for around 30-45 minutes. Furthermore, we will be requiring the Qualcomm USB Drivers to be installed on your PC. However, Windows might conflict with the proper functioning of these drivers. Therefore, you will have to enable the Test Signing Mode before installing these drivers. For that, click on the Start menu, search for Command Prompt, and launch it as an administrator. Now type in the below command and hit Enter: That it. Now Reboot your PC. You have now successfully enabled Test Signing Mode. Now download the Qualcomm USB Drivers from the next section.
