+
+0. Preparation
+==============
+
+0.1 Backup SMS
+--------------
+
+I use SMSGate free software to synchronise every SMS/MMS I receive with
+my mailbox.
+
+https://docs.sms-gate.app/
+
+0.2 Backup contacts/calendar
+----------------------------
+
+I use DavDroid free software to synchronise my contacts and calendars
+with a CardDav server.
+
+https://www.davx5.com/
+
+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!
+
+
+0.6 Downloads
+-------------
+
+To prepare before flashing :
+
+Roms and firwmare:
+
+- Original ROM if the new one does not work
+- HyperOS fastboot ROM
+- Modem firmware
+
+The following is for rooting and ungoogling.
+
+APKs:
+
+- KernelSU-next APK
+- SPIC
+- Native-root-detected
+- Fake GApps
+- Droidify
+- Obtainium
+- Aurora Store
+ 
+KernelSU modules:
+
+- Zygisk-Next
+- LSPosed
+- LSPosed - Zygisk
+- SAN (system apps nuker)
+
+
+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 -ohyperos3/images x ./roms/garnet_modem__OS2.0.205.0.VNRMIXM.zip modem.img
+
+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.
