If you want to get custom ROMs and/or rooting files flashed onto your Lenovo K33 smartphone and don’t want to achieve it via a one-click rooting tool then you can always do it from a custom recovery image instead, so long as there is one available to install.
You can only ever have either a stock recovery image or a custom recovery image installed at any one time. When you install one, it wipes over the other all the time. There are no limits as to how many times you can flash the custom recovery image and then wipe back over it with a stock recovery image.
If you do install TWRP Recovery you’ll have a nice, simple to use GUI for installing unsigned zip files which can be your modifications, rooting files, custom ROM files and anything else you can think of, plus the option for taking and restoring backups. Those backups are NANDroid backups—the most sought after method for backing up thanks to its option of backing up individual partitions and not the full ROM.
This is what you need to install TWRP Recovery on the Lenovo K33 smartphone.
Details of Note
- The custom recovery images available in this guide are only to be installed on the Lenovo K33 smartphone. Most devices have a custom recovery image developed specifically for it, and you shouldn’t install one that is intended for another device unless advised it is okay by a professional.
- You can follow this guide on any of the major three computer operating systems: Windows, Mac, and Linux. You just need to download the right platform-tools file from the Android SDK package when you’re on the Android website, which is walked through during the guide below.
- You can install the official TWRP Recovery application from the Google Play Store or from the TWRP website as an APK, if you have root access on the device already, and get the TWRP installed that way, no ADB required. Once the app is installed, it will be in your Downloads folder. Navigate to the Downloads folder and select the TWRP application. When the application opens tap on the option for flashing the TWRP.
- This device has its own support thread made on the XDA-Developers web forum if you need to ask any questions.
- Download on your computer the latest version of TWRP Recovery: Primary (Americas) | Primary (Europe).
- Download on your computer the universal ADB drivers.
- Download on your computer the platform-tools from the Android SDK.
How to Install TWRP Recovery on Lenovo K33 Smartphones
1. Make sure you’ve installed the universal ADB drivers on the computer. That will make it possible for you to use adb commands as well as the Lenovo K33 smartphone. If you can’t get the Lenovo K33 smartphone connected to the computer, then you can also download the Lenovo USB drivers instead so the computer has both the ADB drivers and Lenovo drivers installed . . . you then can’t go wrong.
2. You need to have the platform-tools part of the Android SDK on your computer. From the download link scroll down until you get to the command line tools section and then download the package that is made for your operating system.
3. Once you have the SDK Manager on your computer, check the box only for the platform-tools, so you end up with the adb and fastboot binaries installed on the computer. (You could also install the drivers from there as well if you wanted.)
4. Pick up the Lenovo K33 smartphone and navigate to the Settings > About and tap your finger over the build number at least seven times so that the Developer Options menu becomes unlocked. Then go back to the Settings, enter the Developer Options menu and then enable the USB debugging mode.
5. Connect the Lenovo K33 smartphone to the computer by using the USB cable that it comes with.
6. Now on the computer open the Command Prompt and type the
adb reboot bootloader command and hit “Enter” on your keyboard to get the Lenovo K33 smartphone into the bootloader mode and ready for the flashing.
7. Make sure you have copied the TWRP image file to the same folder as the adb and fastboot binaries. Also when you’re there, change the name of the TWRP to “twrp.img” by right-clicking the mouse pointer on it and selecting the “Rename” option from the menu.
8. From the command line type the
fastboot flash recovery twrp.imgcommand and hit “Enter” on your keyboard to flash the custom recovery.
9. Lastly type the
fastboot reboot command and as soon as the Lenovo K33 smartphone reboots, hold down the key combination to boot directly into the recovery mode. (If you don’t sometimes the stock recovery will wipe over the custom recovery you just installed.)
The custom recovery image for the Lenovo K33 smartphone is now installed, and you are ready to boot into recovery mode and start flashing the custom ROM or rooting zip files.
TWRP App Installation Method (Root Required)
If you decided to download the TWRP application from the Google Play Store or the APK file from the official TWRP website, then after you open the application you will be given a few different options to choose from. But before even going that far, it’s important to note that you should only install the TWRP APK file from the official TWRP website. If you’re installing it from Git, or any other file hosting website, it might not be the official version, and thus, it won’t have been built or tested by the official TWRP developers and maintainers.
Once the application is open, you’ll need to agree to not hold anyone from TWRP responsible for any issues that your device may face while using the application. This is a standard disclaimer that Team Win puts on top of each of the recovery image files from the official website as well, so it’s nothing new. It just explains that it is your decision to put the custom recovery on your device, and while they work hard to provide a quality product, there are no guarantees that your device isn’t susceptible to damages relating to TWRP while the custom recovery is installed. You can grant the application root permissions now as well. Root access can be obtained by flashing SuperSU, or other appropriate rooting files, from the custom recovery itself. Without root, you won’t have access to some of the app’s features, such as image flashing. It’s here also where you can enable InsightCore (a feature to monitor and record the network performance of your device).
Once you’ve accepted the agreements, you’ll see the TWRP application’s home screen, where you can choose to flash TWRP or view the network statistics. When choosing to flash the custom recovery, you’ll need to scroll and select your device from the list to make sure you are flashing the correct file. When the device is chosen, the TWRP application automatically then searches for the latest version of the TWRP for that device and will continue doing so every day for as long as the app is installed. This interval can also be altered from the Settings in the top right-hand corner of the device’s display when the apps open.
If root access has been enabled, you’ll see the chance to select the custom recovery image and the buttons for flashing the images to boot or from recovery. You should choose to flash the images to recovery. Only use the boot image flashing when you are flashing full boot images, not just kernel zimages.
