[P8 Lite (2017) Discussion] zajyos:
Hello,

I followed a tutorial yesterday to get root access to get rid of some of the pre-installed apps on my newly bought P8 Lite 2017.

I made sure the operation would work on my phone before starting : PRA-LX1 (C432B170), EMUI 5.0, Android 7.0

I supposedly managed to get root access, but somehow without me doing anything for it, all of the Google Apps (including Play Store) have totally disappeared within the phone.

I'll describe below my yesterday's doings. To precise,

I'm a novice

in this and never rooted any phone before.

- Downloaded ADB, Fastboot & Drivers (adb-setup-1.4.3.exe) and installed it.

Got an adb directory created in my C:\ afterwards containing adb.exe, fastboot.exe and two AdbWin .dll .

- Unlocked bootloader doing so : plugged my phone with USB, opened cmd (win+r), went to my C:\adb folder (cd command) and typed adb reboot bootloader; the phone rebooted in bootloader mode. Typed then fastboot oem unlock [code_ive_been_given_on_huawei_website]. Operation was successful.

- Downloaded TWRP (twrp-3.1.1-2-v1-prague.img), renamed it recovery.img and put it in my C:\adb directory.

Opened the cmd (win+r) and rebooted into bootloader mode (adb reboot bootloader). (NB : I tried using the PowerShell cmd but it said "adb isn't recognized as command [...]" "The command adb is nowhere to be found but exists in current spot, PowerShell doesn't load commands from current spot [...]")

Once my phone rebooted in bootloader, I typed in the cmd prompt : fastboot flash recovery recovery.img and operation was successful (two lines of "OKAY" or something similar iirc).

- Downloaded SuperSU (v2.79-201612051815-EMUI5.0.zip), rebooted my phone to put it in.

To mention it, since bootloader unlock the first screen I see is "your device has been unlocked and can't be trusted" with three operations "1. Power up to boot, 2. Vol up to enter erecovery, 3. After 5sec it'll boot automatically". Getting this screen is normal to my understanding.

I moved SuperSU.zip into an external SD once rebooted and plugged via USB.

Then I entered TWRP Recovery Menu, Install-ed the SuperSU.zip, and then Wipe-d Dalvik/Cache and rebooted afterwards.

Phone rebooted once, twice, and ended up booting normally.

Google Apps disappeared since then (no appearance in Settings>Apps), this including Chrome (which was seemingly the sole browser) and PlayStore (rest of Google Apps being what I wanted to erase).

I'm fairly sure that those disappeared after I unlocked the bootloader, but can't be certain of it (operations to get root access took me some time and reboots and the Chrome widget on the main screen has been gone since then iirc).

NB : I see the SuperSU app and when I go to Settings>Google Play "All my applications - See all my applications on the shop" and click on that, nothing happens (I assume it should redirect me to something like the SuperSU dev PlayStore page with his/her developed apps).

I've tried to find out what to do reading some forum posts and the sole post I found that's alike is the following : https://xdaforums.com/mate-9/help/missing-playstore-unlocking-bootloader-t3551269/page2, which end up with a user telling to factory reset, but I read on other posts (not necessarily on xda) that may/might brick and as a novice I would like to get clues on what to do next before going all in on it and bricking it.

Note, I stupidly didn't Backup before doing the operations to get root ... I didn't think of it and the tutorial I followed forgot to mention it.

Thanks in advance for the time spent reading and the help given.
