[Huawei Ascend P7] SharkyBeAre:
FULL INSTALLATION GUIDE OF LINEAGE 13.0 IN HUAWEI P7

Requirements

1. Data transfer cable

2. A laptop or desktop pc

3. Huawei P7 (obviously :silly:)

4. All the files i'll leave as the guide progresses

Observation:

I'm not responsible for you doing the wrong steps and bricking your phone. If you pass look for a tutorial on Youtube to fix it. Without further ado, let's get started.

STEPS IF YOU ARE IN EMUI 3.1 B8XX – ANDROID 5.X.X WITH THE BOOTLOADER LOCKED:

1). The first step is to back up all your data including pictures, songs, photos, documents, and so on a USB or on a pc.

Once we have backed up all personal data we proceed to download the rollback, this file will help us to return to Android version 4.4.2.

2). After downloading we unzip it and pass it to the phone (if you are already on the phone unzip it with some app, just search the Google Play "unzip files" and ready), more specifically in the internal storage or in a folder called "dload" (if you don't have any folders like that, create it and place the file there).

We go to the EMUI 3.1 update app (or directly in the phone settings), and select Local Update, after doing so let the phone restart and install the roll back.

In some cases when the rollback is being installed and goes by 95% will say it failed, do not give greater importance to that message and restart the phone manually. One sign that the rollback worked properly is by observing that when the phone starts doing its power animation (bootlogo) the lower message that says "Powered by ANDROID" will no longer appear.

SO YOU SHOULD SEE THE STARTUP ANIMATION AFTER YOU HAVE INSTALLED THE ROLLBACK

​

WHAT TO DO AFTER YOU HAVE INSTALLED THE ROLLBACK?

3). Once the phone has turned on we proceed to download the B609 version, we will leave it in the "dload" folder of the internal or external memory and install it in the same way we did with the rollback.

Note: If your "dload" still contains the rollback file, delete it and leave only the B609 file.

In some cases when the percentage of the installation goes by 95% it will say that it failed, but once again we will not pay attention to it and restart the phone manually.

Once the phone is switched on, it will tell us that the data partition will not work and that it is time to format the phone, we will select the format option and again the phone will restart and start charging.

As I said before, it may be that by formatting an error, but we will not pay attention to it, we restart the phone manually and configure it.

4). Once configured we will notice that in the notification tray there is no message related to the Android version is Beta, IF IT HAPPENS this they have to download the following file and install it as the previous ones.

If it does not happen they skip this step.

Note: if your “dload” still contains the B609 file, delete it and leave only the file that is used to correct this. (MANDATORY IF YOU HAVE THAT NOTICE IN THE NOTIFICATION TRAY worth the redundancy)

5). After having configured it, we will download the B621 version (unzip it) and proceed to leave it in the “dload” folder of the internal or external memory, installing it as we did with the rollback or the B609.

Note: if your “dload” still contains the notification fix file, delete it and leave only the B621 file.

6) .After having installed the B621, the next thing we will do is download the KingRoot from the browser. I will leave the link in case you don't want to download virus.

7). Once the KingRoot is installed, we tell it to root us, after the procedure is finished, we restart the phone and go to “about the phone” there we look for where it says “Build number” and press it often until it appears We are already developers.

8). We return and enter the developer options, once there, we look for the option that says “USB debugging” and activate it, in doing so we take the data cable and connect the phone to the PC and download the following program (PC).

Link: http://bit.ly/2V7h7RL

9). We decompress it and open the file that says “Get_bootloader_code”, once opened it will show us the following interface.

​

10). Press the "4" key on our keyboard and press "enter", the following will appear.

​

11). Again we press “enter” and a window will appear on the phone saying that “ADB programs” wants to get the benefit of a super user. We grant you the permits and then the advantage will appear in the bootloader code.

12). We copy it to a notebook and then turn off the phone and without disconnecting it from the PC, press the "volume -" keys and the power button.

If we did all the steps correctly when the phone turns on in download mode the phone will say “Phone Unlocked”

13). If you tell us this we can restart the phone in the normal way, and with root we go to the G Play and install Flashify and grant super user permissions.

14). We go to the "backup" tab and make backup of the kernel and recovery stock.

15). We go to the G Play and look for the “EFS backup” application and install it, we make a backup copy of the IMEI.

16). Once having these backups we pass them to the PC to have them safe.

17). Between almost the last steps we go to the following link and download the TWRP 3.0.3

Link: http://bit.ly/2HR2iA6

18). We leave it anywhere on the phone and unzip it.

19). Once decompressed we go to Flashify and select the option to install recovery, we look for the file where we would have saved it and flash it.

20). Already with the TWRP installed we make sure that if it is installed by getting into recovery mode (look for a tutorial on how to enter recovery mode on Huawei devices)

21). If everything works correctly, if not, go back to point 19.

2. 3). Once selected you will understand that there is a small iPhone-style button to slide, we will slide it and we will be in front of the TWRP interface

24). We go to the "backup" option there we check the boxes "system, start and cust" then slide the iPhone style button and wait for the proper backup.

25). We return to the main interface, we give it "restart" and then "system" and wait for the phone to turn on.

26). Once on we connect the phone to the PC and go to the internal memory, once there we look for a folder called “TWRP” we copy it to any part of the PC and it is YOUR decision to delete it from the phone.

27). Download the file of the rom Lineage 13.0

Link: http://bit.ly/2CMzTqt

28). Once the file is downloaded, we pass it to the phone and leave it on a route that is easily accessible.

29). We go back to recovery mode and we go to the "clean" option and slide the iPhone style button.

30). Once cleaned, we return to the main interface and go to where it says "install"

31). Once there we look for the folder where we leave the downloaded Lineage file, and select it.

32). After selecting we slide the iPhone style button and let it load

Note: This process usually takes a long time, DO NOT RESTART the phone until it vibrates and a “restart” button appears, when it appears we give it and if you see a button to slide once more, we click on “do not install” and wait to restart the phone

READY! The phone should turn on correctly and should show the new Lineage interface.

You can now configure the phone and restore everything.

IF YOU ARE IN ANDROID 4.4.2 IN VERSION B6XX AND YOU HAVE THE BLOCKED BOOTLOADER START THE GUIDE FROM POINT NUMBER 5.

IF YOU ARE IN ANDROID 4.4.2 IN THE EMOTION VERSION 2.3 WITH THE BOOTLOADER BLOCKED, START FROM POINT NUMBER 5.

IF YOU ARE IN ANDROID 5.1.1 IN VERSION B8XX WITH THE UNLOCKED BOOTLOADER AND WITH ROOT, START FROM POINT NUMBER 13.

I'm sorry for my English. I hope you find this guide useful. :D
