Install TWRP Recovery on Lenovo Vibe K5 Plus

Yes, you can install TWRP (Team Win Recovery Project) on the Lenovo Vibe K5 Plus (also known as the A6020), and this guide walks you through the entire process. You will need to unlock the bootloader first, then flash the TWRP image using fastboot, and finally verify the installation. The steps are straightforward, but they require careful attention because a mistake can soft-brick your phone.

Why Install TWRP on the Vibe K5 Plus?

TWRP is a custom recovery environment that replaces the stock recovery. It gives you more control over your device, which is essential for advanced Android tasks. With TWRP installed, you can:

• Create full system backups (Nandroid backups) that restore your phone to an exact state.
• Flash custom ROMs, kernels, and mods that are not signed by Lenovo.
• Wipe system, data, cache, and dalvik partitions individually for a clean install.
• Install Magisk or SuperSU to root the device.
• Fix boot loops by wiping caches or restoring a backup.

The Vibe K5 Plus is an older budget device (released in 2016), and its stock recovery is quite limited. TWRP opens up a world of customization and is often the first step for anyone wanting to extend the life of the phone with newer Android versions.

Prerequisites and Important Warnings

Before you begin, understand that this process voids your warranty and carries risks. Flashing the wrong file or interrupting the process can make your phone unusable. Proceed only if you are comfortable with command-line tools.

• Backup your data: Unlocking the bootloader wipes all user data. Copy photos, contacts, and files to a computer or cloud.
• Charge your battery: Ensure your phone has at least 70% charge to avoid it powering off mid-flash.
• Enable Developer Options: Go to Settings > About Phone and tap “Build Numberâ€� seven times. Then enable “OEM unlockingâ€� and “USB debuggingâ€� in Settings > Developer Options.
• Install ADB and Fastboot: Download the official Android SDK Platform Tools on your PC. These include the adb and fastboot commands.
• Download the correct TWRP image: The Vibe K5 Plus (A6020) uses the same TWRP build as the Vibe K5 (A6020) series. Look for a file named twrp-3.x.x-x-a6020.img from a trusted source like the official TWRP website or XDA Developers forum.

Step-by-Step: Unlock the Bootloader

Lenovo officially allows bootloader unlocking for this device, but the process requires a unique unlock code from Lenovo’s website. The code is tied to your device’s IMEI and serial number.

1. On your phone, go to Settings > About Phone and note the IMEI and Serial Number.
2. Visit Lenovo’s bootloader unlock request page (search “Lenovo bootloader unlock� to find the current URL).
3. Fill in the form with your device info and an email address. Lenovo will send you an unlock code, usually within a few days.
4. Enable OEM unlocking in Developer Options (as mentioned above).
5. Connect your phone to the PC via USB and open a command prompt in the Platform Tools folder.
6. Run adb devices to confirm your phone is detected. Then run adb reboot bootloader to enter fastboot mode.
7. Once in fastboot, run fastboot devices to verify the connection.
8. Run fastboot oem unlock and follow the on-screen prompts. Your phone will wipe data and reboot. This step may take a few minutes.

Flashing TWRP via Fastboot

After the bootloader is unlocked, you can flash TWRP. Make sure your phone is in fastboot mode (if not, run adb reboot bootloader again).

1. Place the downloaded twrp.img file in the same folder as your fastboot executable.
2. Run fastboot flash recovery twrp.img. This writes the recovery image to the recovery partition.
3. After the flash completes, run fastboot reboot. Important: Do not let the phone boot normally yet. Immediately press and hold Volume Up + Power simultaneously to boot directly into recovery. If you let it boot normally, the stock recovery may overwrite TWRP.
4. You should see the TWRP home screen. If you do, the installation was successful.

Common Problems and How to Fix Them

Several issues can arise during or after flashing. Here are the most common ones:

• “FAILED (remote: unknown command)â€�: This usually means the bootloader is still locked. Double-check that you completed the unlock process and that OEM unlocking is enabled.
• Boot loop after flashing: If the phone keeps restarting, boot into TWRP (Volume Up + Power) and wipe the cache and dalvik cache. If that fails, restore a backup or reflash a stock ROM.
• TWRP doesn’t stick after reboot: Some devices automatically replace the custom recovery on the first normal boot. To prevent this, boot directly into TWRP after flashing and then flash a “no-verity-opt-encryptâ€� zip or re-flash TWRP using the “Install Recovery Ramdiskâ€� option in TWRP itself.
• Phone not detected by fastboot: Try a different USB cable or port. Ensure you have the correct device drivers installed on your PC.

After Installation: What to Do Next

Once TWRP is running, you can immediately create a full backup. This is the safest first action. In TWRP, tap “Backup,� select all partitions (System, Data, Boot, EFS, etc.), and swipe to back up. Store the backup on an external SD card or transfer it to your PC later. This backup is your safety net for any future experiments.

You can now flash custom ROMs. For the Vibe K5 Plus, popular options include LineageOS, Resurrection Remix, and crDroid. Make sure to download a ROM and GApps (Google Apps) that are specifically built for the A6020. Flash them in TWRP by tapping “Install,� selecting the ZIP files, and swiping to confirm. Always wipe the system, data, and cache before switching to a new ROM.

Frequently Asked Questions

Will installing TWRP erase my data?

Unlocking the bootloader will erase all data. Flashing TWRP itself does not wipe data, but the bootloader unlock step does. So back up everything before you start.

Can I uninstall TWRP later?

Yes, you can. To return to stock, download the stock firmware for the Vibe K5 Plus and flash it using the Lenovo Smart Assistant or by flashing the stock recovery image via fastboot. This will remove TWRP and relock the bootloader if you wish.

Is it safe to root my phone after installing TWRP?

Rooting is generally safe if you use a reputable method like Magisk. It gives you superuser access, which can be powerful. Be careful with root-only apps, as they can cause system instability if misused.

What is the difference between TWRP and a custom ROM?

TWRP is a recovery tool that runs independently of the Android OS. A custom ROM is a modified version of Android itself. You use TWRP to install a custom ROM, but TWRP is not a ROM.

Why does my phone show “No OS installed� after wiping in TWRP?

This message appears when the system partition is empty. It usually happens if you wipe the system partition without flashing a new ROM. Simply flash a compatible ROM ZIP to install a system.

Can I install TWRP without unlocking the bootloader?

No, the bootloader must be unlocked to flash any custom recovery. Attempting to flash without unlocking will fail and may trigger security warnings.
