Reboot Bootloader Mode on the HTC U11

In order to use your new HTC U11 properly and for being able to take full advantage of its features and performance, you first need to learn how to complete the basic Android operations. These operations can help you smartly deal unpleasant situations, can guide you through customizations and can also help you tweak the Android system that runs on your HTC U11. So, in that respect, today I am going to show you how to reboot bootloader mode on your smartphone.

Entering bootloader mode is a process quite similar with other basic Android operations such as: reaching recovery mode, getting into download mode or making a hard reset. Therefore, completing all the steps from below should be a piece of cake even if you are a newbie who is using the Android platform for the first time. Moreover, you have nothing to worry about – rebooting into bootloader mode is an official process supported by HTC and by Google.

So, for being able to successfully reach bootloader mode you won’t have to use complex or risky tools. Everything can be ensured through built-in settings and features which means that you will keep everything safe and secured all the time – in that respect, the warranty of your HTC U11 won’t get void once you will start one of the methods from down below.

The bootloader mode is a dedicated environment that runs on your HTC U11 and which can be accessed separately / independently from the stock Android mode. Usually the bootloader mode is required when you are trying to perform manual operations from your computer. On these situations you are most likely using a dedicated software on your PC that must ‘communicate’ with your device. Well, most programs can recognize your phone only if its running on bootloader mode.

Therefore, here are the most common operations that will require the bootloader mode: unlocking the bootloader of your HTC U11, installing a custom recovery image such as TWRP recovery, manually updating with custom ROMs, overclocking the CPU frequencies, flashing custom kernels or MODs or even gaining root access.

As pointed out, the bootloader can be safely accessed at any moment. Reaching this mode is also safe and secured, though some precaution measures should be considered if you are planning to tweak your device after putting its system into bootloader mode. So, as a general rule, make a backup before completing anything else. You can choose to make a Nandroid backup for saving the current Android platform that runs on your handset or you can just save what’s personal by using different backup and restore solutions: syncing your files with your own Google Account, saving your data by using built-in cloud storage platforms, or using backup and restore tools from Google Play (just make sure you get already tested, though trustful, apps from the market).

All the methods from below are general ones. This tutorial can be used anytime you need to, even if you already tweaked your smartphone. Therefore, in a few words, you will be able to access the bootloader mode without problems when your HTC U11 is locked, rooted, installed with stock or with custom recovery image, running on a locked or unlocked bootloader and so on.

Another thing that should be ensured before choosing to do anything else is a charging process. Your phone should run on more than 50% power or else its system might get switched off right in the middle of the reboot operation that’s explained below. Also, if a sudden shut down occurs your HTC U11 might get soft bricked as various malfunctions can be caused within the Android core system. Therefore, as a general conclusion, try to avoid such unpleasant situations and be careful when applying something on your smartphone – in our case, plug in the charger if that’s required.

How to Reboot Bootloader Mode on the HTC U11

Method 1

  1. Your smartphone must be turned off.
  2. So, if different, power off your phone and wait while the shut down operation is completed.
  3. Press and hold the Volume Down and Power buttons together for a few moments until download mode is displayed.
  4. From download mode use the Volume rocker keys in order to highlight the bootloader option.
  5. Confirm by pressing on Power button.
  6. That’s it; wait while the bootloader mode is being booted on your HTC U11.

Method 2

If you are an advanced user then this method is for you – this process is more helpful as it already uses a computer and adb commands. Thus, right from the start you need to prepare a computer or a notebook – there, you have to install Android SDK (for Windows use this tutorial and for MAC OS X / Linux use this tutorial instead) and flash your HTC U11 drivers. Then, head your attention towards your phone: from “menu – > settings – > developer options” you must check the USB Debugging option. Note: Developer rights can be established by tapping repeatedly on Built Number until the ‘you are a developer’ message is displayed. Finally, apply:

  1. Switch on your smartphone and power on your computer.
  2. Use your phone’s USB cable and establish a connection between your handset and your computer.
  3. Navigate to the Android SDK folder on your computer.
  4. You have to open a cmd window from that location – press and hold the Shift keyboard key while right clicking on any blank space and then select “open command prompt window here”.
  5. When done, in the cmd window enter: adb reboot bootloader.
  6. That’s it; the bootloader mode should be automatically rebooted into bootloader mode.

Method 3

There are third party apps available on Google Play that can help you reboot your HTC U11 into bootloader mode. Unfortunately, most of these apps are working only with a rooted Android OS. Quick Boot is an example of such software that can guide you through the reboot sequence. All you have to do is to download the app from the Market, to install it on your phone and to run the software when done. Then, just follow on screen prompts in order to reboot into the desired mode.
