How to Flash TWRP on LG K20 Plus

Step 1: Firstly, you must booth into the fastboot mode: Turn on phone switch off and then hold VOLUME DOWN KEY and while holding the key, connect device to the computer using USB Cable. This will boot the LG K20 Plus into fastboot mode. Alternatively, you can type the command into adb terminal:

adb reboot bootloader

Step 2: Now, again open the command prompt in adb tool, and type or copy-paste this command:

fastboot flash recovery <path_to_recovery.img>

(Replace path_to_recovery.img with exact path, i.e. c://users/William/downloads/recovery.img”. You can get the recovery.img file in downloaded recovery file)

Step 3: This will start the flashing process, and it will take about 2 seconds to complete. After process gets completed, simply unplug the usb cable from phone and turn it off by removing the battery, then again inserting it in.

Step 4: Now, you need to boot to the recovery for the first time. For doing the same, just HOLD VOLUME DOWN + POWER keys, until the LG Logo appears and then temporarily release the POWER button, and then press and hold it back until the ‘factory reset’ option appears on the screen.

Procedure to Root LG K20 Plus on Android 6.0 Lollypop and Android 7.0 Nougat

Step1: On the TWRP interface, go to Wipe > Format Data and enter ‘yes’. This will wipe and decrypt the automatically encrypted filesystem. Then reboot into recovery by going to Reboot>Recovery.

Step 2: After the phone boots into recovery, connect it to PC and enable the ‘MTP’, and then transfer the downloaded ‘no-verity-opt-encrypt-**.zip’ and ‘SR1-SuperSU-v2.78-SR1-20160915123031.zip to the LG K20’s internal storage. Then disconnect the device from computer.

Step 3: Just tap on ‘Install’. Now browse/ navigate the phone and select ‘‘no-verity-opt-encrypt-**.zip’, and then swipe ‘Swipe to confirm Flash’ button, which is located bottom of the screen.

Step 4: The flashing process has been started and will take few seconds to complete. Once it gets completed, follow the same method (Step 1 to 3) to flash the SR1-SuperSU-v2.78-SR1-20160915123031.zip file (Downloaded earlier). The flashing process will take 1 or 2 minutes (Normally) to complete, and then phone will take 4-5 minutes for first time boot.

Note: Developer mentioned that device might give the bootloap once or twice on the Metro PCS splash screen. We have to Flash no-verity-opt-encrypt.zip, because the boot image has dm-verity, otherwise the LG K20 Plus TP260 and MP260  phone doesn’t not boot and system modifications are disabled. Installing SuperSU or phh-superuser and flashing no-verity-opt-encrypt.zip rectifies the problem.
