As rootear and unlock the bootloader of honor 7 European PLK-L01 B121

This mobile has 3Gb of Ram, 8 cores 64 bits, 5,2″ of screen, fingerprint reader, camera 20 MP, Infrared remote control, 4G coverage, SD, Lollipop 5.0.2 349 € on the web amazon the vmall.


1 – Download the driver for installing windows Hisuite and then connecting the phone via USB.

2 – lower pack of root . It includes and TWRP folder. Remove everything as like this in the internal memory (not in SD) .

3 – lower android sdk and install it in c:\android-sdk. Run the sdk manager and then install Android SDK tools, Android SDK Plattform-tools and USB driver from the same application.

4 – Lower flashing pack. It includes recovery of stock B121 and TWRP .Copiar both immediately inside c:\android-sdk Plattform-tools the recovery.img files and twrp_cn.img


– This has happened to me, if you create an id of huawei using the same mail your facebook (that is what you should do but does not work), maybe when you pinchéis in with facebook login screen only you cool and do nothing more or also that once you entered the codes leave a message “Sorry, you must use a phone account to submit this application”. The solution to this is to create 2 new accounts with a new same mail and facebook huawei.

– modo Fastboot : Off the phone with the usb connected. Squeeze and hold the volume button – and the power button simultaneously until you exit the bootloader screen.

– Recovery Mode : Off the phone with the usb connected. Squeeze and hold the volume button + and the power button simultaneously until you exit the recovery screen

Enable USB Debugging Mode : Go to settings-about phone and press 7 sometimes build number to display the development options, usb debugging active there.

This method is proven to root EMUI version 3.1 with firmware B121 (PLK-L01C432B121)

– Remember that this mobile can be left as it was new, I mean that if we unlock the bootloader or change the recovery, both changes can be reversed leaving factory to send to repair if necessary.
