0. Preparation
|
||||||
|
==============
|
||||||
|
|
||||||
|
0.1 Backup SMS
|
||||||
|
--------------
|
||||||
|
|
||||||
|
I use SMSGate free software to synchronise every SMS/MMS I receive with
|
||||||
|
my mailbox.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
0.2 Backup contacts/calendar
|
||||||
|
----------------------------
|
||||||
|
|
||||||
|
I use DavDroid free software to synchronise my contacts and calendars
|
||||||
|
with a CardDav server.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
0.3 Backup system settings and apps
|
||||||
|
-----------------------------------
|
||||||
|
|
||||||
|
I used the default backup utility to backup system settings, custom apps
|
||||||
|
and app data. I did it in two times since your can select what is
|
||||||
|
backupped, first of all the system settings (around 90MB archive), and
|
||||||
|
then the apps (around 3OGB).
|
||||||
|
|
||||||
|
It creates a zipfile on the phone's storage, that I copied on my
|
||||||
|
computer's storage by mounting the phone via MTP.
|
||||||
|
|
||||||
|
The Android tool is very slow, and uses a lot of storage space. I first
|
||||||
|
cleaned the phone data to make some room, and then I switched the device
|
||||||
|
to "airplane mode" and let the phone plugged with my computer USB to
|
||||||
|
avoid running out of battery.
|
||||||
|
|
||||||
|
I should have been more careful before saving the applications data, as
|
||||||
|
some were just HyperOS "Mi" bloatware, some were not used anymore, and
|
||||||
|
some were too big : OSMAnd takes most of the size with it's maps, almost
|
||||||
|
10GB compressed, and some other mistakes included their cache as
|
||||||
|
streaming music players.
|
||||||
|
|
||||||
|
Finally, the worst suprise was the lack of "Google Messages" backup, and
|
||||||
|
"Google Contacts". I was surprised, but should not have be : they force
|
||||||
|
to use their cloud to synchronise the data of their apps. I avoided
|
||||||
|
doing so, and still avoid using a Google account on my Android
|
||||||
|
smartphone. The use of DAVx and SMSGate saved the thing, but still, I
|
||||||
|
don't have any history on "Google Messages" and I had to reconfigure
|
||||||
|
"Google Contacts". As I'm almost careful with adressbooks, I may not
|
||||||
|
have lost contacts... The worst that could happen is to lose some
|
||||||
|
details like history of phone calls and blocklist.
|
||||||
|
|
||||||
|
That should be another full article, as I still do not find viable
|
||||||
|
alternatives to these two Google apps.
|
||||||
|
|
||||||
|
0.4 Backup data
|
||||||
|
---------------
|
||||||
|
|
||||||
|
Copy via MTP mount the data you want to keep. Pictures / Music /
|
||||||
|
Documents.
|
||||||
|
|
||||||
|
To ease that, you can also use a Nextcloud server or the Localsend app.
|
||||||
|
|
||||||
|
0.5 Pre-requisites
|
||||||
|
------------------
|
||||||
|
|
||||||
|
On the target device : Bootloader is unlocked and Fastboot is installed.
|
||||||
|
Developer mode switched ON.
|
||||||
|
|
||||||
|
On the computer : a GNU/Linux OS and adb/fastboot CLIs installed.
|
||||||
|
|
||||||
|
Test the connectiong by plugging the device to the computer via USB and
|
||||||
|
launching in a terminal:
|
||||||
|
|
||||||
|
adb devices
|
||||||
|
|
||||||
|
Your device UID should appear.
|
||||||
|
|
||||||
|
Test fastboot by rebooting to it with the following command :
|
||||||
|
|
||||||
|
adb reboot bootloader
|
||||||
|
|
||||||
|
Your device should reboot and boot with the "fastboot" logo. It should
|
||||||
|
remain still (nothing happens means it works).
|
||||||
|
|
||||||
|
|
||||||
|
IMPORTANT: Do not continue the procedure if any of the previous test is
|
||||||
|
not successful!
|
||||||

||||||

1. Procedure
|
||||||
|
============
|
||||||
|
|
||||||
|
The duration of the procedure can go from 1 hour to 3 hours depending on
|
||||||
|
what you're trying to achieve.
|
||||||
|
|
||||||
|
Backupping + Flashing : 1 hour Rooting : 1 hour Ungoogling : 1 hour
|
||||||
|
|
||||||
|
The tests may take an additional hour.
|
||||||
|
|
||||||
|
Make sure to have sufficient battery on the device, that your USB cables
|
||||||
|
will not fail, that you have sufficient storage space on your computer
|
||||||
|
and your device. Close any applications and distractions, as an error
|
||||||
|
can happen quickly.
|
||||||
|
|
||||||
|
Re-ensure that your data is well backupped before starting - or that you
|
||||||
|
really don't care and won't complain.
|
||||||
|
|
||||||
|
1.1 Flashing a new OS on your Android device
|
||||||
|
--------------------------------------------
|
||||||
|
|
||||||
|
Extract the xiaomi.eu HyperOS archive on your computer.
|
||||||
|
|
||||||
|
7z -ohyperos3 x ./roms/xiaomi.eu_GARNET_OS3.0.2.0.WNRCNXM_16.zip
|
||||||
|
|
||||||
|
Overwrite the modem.img file fixed for garnet.
|
||||||
|
|
||||||
|
7z -ogarnet_modem ./roms/garnet_modem__OS2.0.205.0.VNRMIXM.zip cp
|
||||||
|
garnet_modem/modem.img hyperos3/images/
|
||||||
|
|
||||||
|
Flash and format the device.
|
||||||
|
|
||||||
|
cd hyperos3 ./linux_install_and_format_data.sh
|
||||||
|
|
||||||
|
Answer yes to all questions.
|
||||||
|
|
||||||
|
I modified the script to use the version of fastboot installed on my
|
||||||
|
system, for my own security, but it should not be a problem to run with
|
||||||
|
the fastboot binary included in the archive.
|
||||||
|
|
||||||
|
After executing this script, your device will reboot on the new
|
||||||
|
operating system. You should let it the time to boot, and then follow
|
||||||
|
the first-launch guide on the device.
|
||||||
|
|
||||||
|
I always refuse to create a Google account to attach to my device, so
|
||||||
|
when asked I just skip. I also disable the lock-screen before the
|
||||||
|
installation procedure is totally finished.
|
||||||
|
|
||||||
|
Test if the network works well, and if the basic applications are
|
||||||
|
running. You can the restore the backupped data.
|
||||||
|
|
||||||
|
1.2 Restore your apps and settings
|
||||||
|
----------------------------------
|
||||||
|
|
||||||
|
Plug your device to your computer and set it to Airplane mode.
|
||||||
|
|
||||||
|
Specify 'File transfer mode' on the popup (instead of charging only) and
|
||||||
|
copy the zipped files that you saved to your computer in section "0.3"
|
||||||
|
in the "MIUI/backup/Allbackup/" folder of your device.
|
||||||
|
|
||||||
|
Then, go to the applcation list and search "Backup". You should be able
|
||||||
|
to open the same application that in section "0.3", and on the "Restore"
|
||||||
|
tab, you should see the date of your backups. Just select them and tap
|
||||||
|
on "Restore".
|
||||||
|
|
||||||
|
1.3 Rooting the device
|
||||||
|
----------------------
|
||||||
|
|
||||||
|
This step is pretty simple. First, enable developer-mode and copy the
|
||||||
|
"boot.img" file of your ROM on your device.
|
||||||
|
|
||||||
|
Then, install the "KernelSU-Next" apk through adb.
|
||||||
|
|
||||||
|
Launch the KernelSU-Next app on your device, and select the previously
|
||||||
|
copied "boot.img" file : patch it.
|
||||||
|
|
||||||
|
Once patcher, copy the "kernelsu_next_patched_CURRENT_TIMESTAMP.img"
|
||||||
|
from the device to your computer. Then, flash it with fastboot.
|
||||||
|
|
||||||
|
adb reboot bootloader
|
||||||
|
|
||||||
|
Once rebooted :
|
||||||
|
|
||||||
|
fastboot flash boot "kernelsu_next_patched_CURRENT_TIMESTAMP.img"
|
||||||
|
fastboot reboot
|
||||||
|
|
||||||
|
After rebooting, launch the KernelSU-Next app, you should see the
|
||||||
|
"Working [LKM]" label just after the title bar. You device is rooted!
|
||||||
|
|
||||||
|
1.4 Ungoogle
|
||||||
|
------------
|
||||||
|
|
||||||
|
I mostly followed the following tutorial on XDA forums.
|
||||||
|
|
||||||
|
https://xdaforums.com/t/guide-unlocked-bootloader-root-ungoogle-microg-on-any-stock-rom.4752360/
|
||||||
|
|
||||||
|
These are the specific things I did :
|
||||||
|
|
||||||
|
- I used the noogle-magisk fork from becknik to fetch the MicroG apksj
|
||||||
|
https://github.com/becknik/noogle-magisk/tree/master
|
||||||
|
|
||||||
|
- I had to use Zygisk-Next implementation instead of the ones proposed
|
||||||
|
in the tutorial, as the others were complaining on my Kernel version.
