[GUIDE] Havoc P and other P GSI with anykernel2 8.1 to P boot patch [temp]

First things first
1. Remove all pattern, fp, face data and BACKUP all Partition in TWRP ( I lost baseband trying GSI images, those backup saved me).
2. TWRP should be installed and also Force disabled Encryption should be flashed.
Now follow the steps
1. Go to TWRP, wipe dalvik/cache, cache, system, data
2. Go back and Flash HavocP system image as System or you can try other P GSIs..
HavocP-arm64_aonly_vanilla_nosu-0830.zip
( You can check the source here for updates).
Optionally you can flash arm64 Gapps 9.0 (nano or micro is recommended) opengapps.org
3. Next without exiting TWRP flash this zip, this one patches boot for Android P GSI image compatibility..
POST-sGSI_3_v0.5.zip
4. Now go to wipe menu and wipe Dalvik/cache, cache, data and reboot.
For audio distortion fix:
[Temp] How-To Fix Audio distorted on P GSIs
For Volte: not found any fix yet, but may be fixed by tweaking build.prop like some other devices.. Will add if found.
May this line be added in Vendor/bin/init.qcom.sh like One plus 3.
Code:
# Hack to get IMS up and running on GSI
if [ -f /data/system/users/0/settings_global.xml ]; then
sed -i 's/"multi_sim_data_call" value="1"/"multi_sim_data_call" value="-1"/g' /data/system/users/0/settings_global.xml
restorecon /data/system/users/0/settings_global.xml
fi
This thread is temporary.. Will close it if stable Havoc is released by the Devs

Hi,
Thanks a lot...
Will try that and report if it worked for me
Hope the back up won't fail on me !!!
EDIT : tried to do exactly as you said...
It may be worth mentioning a thing or two...
1°) that you should install GApps also...
2°) that it takes some time for the device to get out of the "Pocophone" splash screen
3°) that it may take some time until the SIM card is recognized
Regards.

Please test multitouch issue, if it exists in this rom.

1. Oh sorry opengapps is released officially , updating op..
2. If pocophone splash screen is stuck, force reboot. Booting is fast for me just like stock rom. That stucking happened once in Havoc, rebooting solved.
3. For me sim detection and registration was fast with Jio 4G and Airtel.. BTW I am sure there is conflicts in Modem and OS (this caused baseband 'unknown').. So sometimes it may some time for sims to get recognized or even not be recognized after booting.
In short, these GSIs are not stable.

No, the multitouch bug, ghost touch is different.

Hi,
Same impression here : Treble needs a lot more work to deliver what Google is aiming at !
I now understand why some ROM devs do not want to release GSI ROM images
Regards.

If I wipe system before flashing Havoc image, I cannot flash gapps P (as it seems to be "seeing" the other slot even on oreo).
If I do not wipe system, I can follow the steps and boot Havoc. But an error message appears: "Android System: There is an internal problem with your device. Get in contact with your manufacturer to know the details". Each boot, same message.

It is due to mismatch of ro.vendor.build.fingerprint value in build.prop in System and Vendor..
FIX:
1. Connect data cable to PC and boot into twrp
2. Go to Advanced/file manager
3. Copy build.prop from both Vendor and System to Sdcard, so that you copy them to your PC and edit.
4. In PC, Copy those build.prop files from sdcard and change the value of ro.vendor.build.fingerprint from build.prop (system) to build.prop (vendor).
5. Now overwrite the edited build.prop (vendor) to Vendor in the same process and you may give permission 644 (rw-r--r--) that vendor/build.prop
6. Reboot and check

What's the point of flashing the postGSI fixes, when it, at least for me and for my guide, works well without them.
I don't see the point.

[GUIDE][GSI][9.0] How to get the HavocOS 2.9 GSI running on the Xiaomi Mi 9 Lite

DISCLAIMER: First off, I'm not a dev; I'm someone with a lot of time to spare that's trying to save quite a few headaches to people that don't like MIUI. If you're actually one of the talented people that worked on this stuff and don't like seeing your work shared here, just hit me up.
Secondly, all of this has been tested on my Mi 9 Lite. I can't guarantee it'll work on other variants such as the meitu edition or the Mi CC9, but then again I can't see why it wouldn't.
Lastly, please take all your due precautions before doing this: take your backups, be sure to have a plan in case anything goes wrong, the whole deal.
INSTRUCTIONS:
0) Unlock your bootloader and flash Brigudav's TWRP;
1) Format your data partition. This is mandatory, you need to get rid of the encryption!
2) Download and flash the latest Unofficial LineageOS 16 by gringo80. Compared to the xiaomi.eu build that I recommended before, the Vendor from LOS enables the use of the wide angle lens in GCam, Hypercam and ANXCamera.
3) Reboot into TWRP without booting into system; this ensures that the System partition is properly mounted before proceeding;
4) Under "Advanced Wipe", select the Cache, Dalvik, Data and System partition, but don't select "Vendor". Wipe them;
5) Download the A/B HavocOS 2.9 GSI, extract it and place the .img file into your phone's storage;
6) Under "Install", press "Install image file", select the GSI and flash it into the System partition;
7) Flash the nano OpenGapps (ARM64) package for Android 9.0;
7a) If you get an error that says that the System partition is too small, follow these steps: Wipe > Advanced Wipe > Select the System partition > Repair or Change File System > Resize File System. Flash the GApps package again and it should work;
8) Boot the phone, set it up and enjoy!
8a) If you need root, once you've passed the initial setup simply reboot into TWRP and flash Magisk 20.1.
GSIs' COMMON PROBLEMS AND FIXES:
To get Viper4Android working, install the V4A 2.7 apk from XDALabs, flash the GSI Enabler Magisk Module;
If your FOD is slow or inaccurate, set up the same finger twice;
To get ANXCamera working, be sure that the "ro.product.device" string's value in your build.prop file is set to "pyxis" and to have downloaded the "139.PastAdorableHawaiianmonkseal" build.
If you use Titanium Backup to restore your apps, the restoring process might get stuck on certain apps (for instance, Solid Explorer, Sound Cloud, Google Photos and so on). To fix this, simply go to the Play Store and manually download the app. Once it finishes installing, the backup will resume automatically;
To fix the Bluetooth audio in-call not working, flash this Magisk module.
BUGS:
DT2W doesn't work;
You might experience a slightly worse cellular reception depending on your phone's model;
That's... pretty much it!
STUFF THAT WORKS EVEN THOUGH I TOTALLY EXPECTED IT TO FAIL:
EdXposed (SandHook). If you experience sporadic SystemUI crashes, it's Gravity Box's fault;
The Screen OC Mod posted by @HelloRickyLee. I use the 72Hz dtbo file, since everything above that freezes my phone once I press the power button, but hey! Not complaining!
And that's pretty much it.
Enjoy!
Credits: The HavocOS team; xiaomi.eu team; @gringo80, @brigudav,

I already dont use DT2w, so tempted to try this once my waiting time is over thanks!

I am using this Rom from yesterday and I am very surprised because it is working prety well.
Just two or three bugs that I can live with.
Almost all personalizations of Havoc are operative.

Right? I was genuinely surprised at how well GSIs work, I'm glad I'm not the only one thinking so. I'll try to keep the post updated in the case of new builds being released, but since HavocOS 3.0 is already out in fairly sure that the one I linked in the OP is the final build.

Failure to get the rom out. Loops on screen where says MI.

Offline charging works?

has point 7a in OP any negative effects, when I switch to los17 or miui roms?

Not for me. I've since switched to LOS17.1 (and tried a couple of MIUI-based ROM for good measure) and I've never had any issues.

That way you will have a stable GCam which everything works (Sanity's), but you can also have a latest version of GCam for features that v9.6 of Sanity's doesn't have, like astro mode etc.

!DISCLAIMER!
Most people I know (including myself) who used my Guides and steps, did that with success many times. If you don't follow exactly the steps or you do a mistake during the process, I do not take any responsibility for any unexpected results or damage that may happen. However I am here to help if something goes wrong, just ask in the thread.​
AMD RYZEN/INTEL FASTBOOT FIX
Some AMD Ryzen or Intel Systems may have problems to recognize your device in fastboot. Try the following ways:
1. Install Fastboot Drivers (Extract the folder for windows 10) at Device Manager while your device is connected in Fastboot mode.
2. Download this .bat file (unzip it) or manually create a .bat file with these lines below, and run it as an administrator, then reboot:
Code:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "osvc" /t REG_BINARY /d "0000" /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipContainerIdQuery" /t REG_BINARY /d "01000000" /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipBOSDescriptorQuery" /t REG_BINARY /d "01000000" /f
3. Enable USB Debugging at device (Settings > Additional settings > Developer options > USB Debugging) and give authorization after connecting it to PC.
4. Use USB Hub.
5. Use USB Type-A 2.0.
6. Install AMD Ryzen Chipset Drivers or Intel Chipset Drivers.
Check the steps an another user did to make it work here.
If this doesn't help, unfortunately you have to use Intel System which is more likely to work.
UNLOCK BOOTLOADER
Note: Some AMD Ryzen Systems may have problems to recognize your device in fastboot. [Read the AMD Fastboot Fix Guide above]
Please keep in mind by Unlocking Bootloader the device will reset and all your data will be lost. Make a backup of your data first to PC or to USB.
1. Create a Mi account on Xiaomi’s website.
2. Add a phone number to your Mi account.
3. Insert a SIM into your phone (If you haven't added already). [Do not insert 2 SIM, only 1 until the Bootloader is unlocked. If you have 2 SIM into your phone, remove 1 and reboot.]
4. Enable developer options in Settings > About Phone by repeatedly tapping (7 times) on MIUI Version.
5. Link the device to your Mi account in Settings > Additional settings > Developer options > Mi Unlock status. Also enable USB Debugging.
6. Download the Mi Unlock app (Windows is required to run the app).
7. Run the Mi Unlock app and follow the instructions provided by the app.
8. Reboot your device into Fastboot mode. For that simply turn off your device, press the Power Button + Volume Down (–) button at the same time. Then connect the device to the Windows PC/laptop via a micro USB cable.
9. After device and Mi account are successfully verified, the Bootloader should be Unlocked and your device will restart by itself.
INSTALL CUSTOM RECOVERY
Fastboot Method (No Custom Recovery currently installed)
Note: Some AMD Ryzen Systems may have problems to recognize your device in fastboot. [Read the AMD Fastboot Fix Guide above]
1. Make sure your Bootloader is Unlocked.
2. Enable developer options in Settings > About Phone by repeatedly tapping (7 times) on MIUI Version.
3. Enable USB Debugging in Settings > Additional settings > Developer options > USB Debugging.
4. Download a custom recovery of your choice and copy the .img to your Internal Storage or to SDCard. [You can find a recovery of your choice in my Collection]
5. Download the portable Minimal ADB and Fastboot and run cmd.exe
6. Reboot to Fastboot mode by pressing Power Button + Volume Down (–) and keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
7. Once the device is in Fastboot mode, connect your device to PC and verify you can find it by typying in cmd: fastboot devices.
8. Boot into Recovery by typing in cmd: fastboot boot <recovery_filename>.img (The file may not be named identically to what stands in this command, so adjust accordingly and write the full path of it, check the example below).
This command will not flash permantly the recovery, it will just temporary boot into it and afterwards you will flash permantly the twrp.img you copied into your Internal Storage or SDcard in recovery partition.
For example:
Code:
fastboot boot C:\Users\Retrial\Desktop\twrp-beryllium-v3.7.0-A12-V2.img
9. Now into TWRP, press Install > Install Image > Locate & Select the twrp.img you previously downloaded and copied from PC into your Internal Storage or to your SDcard > Choose Recovery and Flash!
10. Go back into Home page of TWRP and press Reboot to Recovery or manually by holding Power Button + Volume Up (+) until you boot to Recovery.
11. Done! You now have a new Custom Recovery installed.
Recovery Method (Custom Recovery already installed or booted)
1. Download a custom recovery of your choice. [You can find a recovery of your choice in my Collection]
2. Reboot to Recovery by holding Power Button + Volume Up (+).
3. Press Install > Install Image.
4. Locate the recovery.img you recently downloaded.
5. Select it and choose the option Recovery and Flash.
6. Go back and Reboot to Recovery.
7. Done! Your new recovery should be installed.
CLEAN INSTALL CUSTOM ROM
Note: If you have issues after flash check possible solutions here:
Check integrity of all downloads (compare checksums), do the downloads again.
Make sure you Wiped everything and Formated Data (format data not just wipe) except external SDCard and USB OTG.
Flash only the ROM (without GApps and Magisk) and check if the problem persists. If yes, flash another ROM.
Try other GApps package.
If nothing helps, go back to stock and start from scratch.
Note: You can also Flash Custom ROM using ADB sideload Method.
What is System_EXT? Check out here.
You can also do the same steps below to install Stock MIUI Recovery ROM.
1. Backup all your data to PC or to external SDCard. [All your data into Internal Storage will be lost on step 7 while Formating Data or Wiping Internal Storage]
2. Unlock Bootloader. [Read the Unlock Bootloader Guide above]
3. Download: [You can find everything in my Collection]
Custom Recovery of your choice. [Recommened to use Unofficial TWRP by REIGNZ3 (A12_System_Ext) for A12L+ ROMs]
Custom ROM of your choice.
GApps (be sure you have selected Platform: ARMx64 and the proper Android version of the ROM you are going to flash) if the ROM you are going to flash does not include. [Optional]
Magisk Root. [Optional]
Disable Force Encryption or Encryption. [Optional] (Read DFE & Encryption Guide above)
4. Move all these files in one folder to your PC or to External SDCard if you have one.
5. Install Custom Recovery. [Read the Install Custom Recovery Guide above]
6. Reboot to Recovery Power Button + Volume Up (+)
7. Installation:
Steps without external SDCard:
Select Wipe > Advanced Wipe
Select Dalvik / ART Cache, System, System_Ext, Data, Internal Storage, Vendor, Cache and then Swipe to Wipe. [All your data into Internal Storage will be lost]
Go back > Press Reboot > Reboot to Recovery again. [That step needed for the next step of formating the data because TWRP by REIGNZ have issue]
Go back and select Wipe > Format Data > type yes [All your data into Internal Storage will be lost]
Connect your device to PC while you are on TWRP and transfer into Internal Storage, the ROM, GApps etc. and the files you want to flash.
Flash ROM > GApps [Optional]
[Optional] Mount Vendor and Flash DFE [Optional - Not Recommended] or Encryption [Optional] (Read DFE & Encryption Guide above)
Reboot Enjoy!
[Optional] If you want to root, reboot once again to TWRP Recovery and flash Magisk then reboot to system and enjoy!
Steps with external SDCard:
go to Advanced > File Manager > External_SD and delete all folders in ur ext sd card (For example you should delete: Android, .android_secure, LOST.DIR, DCIM, etc) except your personal files/folders and the folder with your custom ROM/Gapps/Magisk/DFE or Encryption you want to flash.
Each app on your phone with the WRITE_EXTERNAL_STORAGE permission may create files or folders in ur sdcard. Most of these folders have once been created by one of these apps and many of them may be deleted with a few exceptions (e.g. Android, .data, .android_secure, these contain important system or app data like a game's downloaded content):
.android_secure: apps installed and then moved to sdcard
Android: app data/cache
data: app data
.estrongs: ES file manager
LOST.DIR: sort of trash folder (collects recovered files after phone crashes)
DCIM: phone gallery's photos and previews
OTA-update: Over The Air update service
ppy_cross: an unknown third-party app's data.
So I recommend to delete them so you can put your phone/sdcard in a clean state and is guaranteed to be able to re-create these folders.
Select Advanced Wipe
Select Dalvik / ART Cache, System, System_Ext, Data, Internal Storage, Vendor, Cache and then Swipe to Wipe. [All your data into Internal Storage will be lost]
Go back > Press Reboot > Reboot to Recovery again. [That step needed for the next step of formating the data because TWRP by REIGNZ have issue]
Go back and select Wipe > Format Data > type yes [All your data into Internal Storage will be lost]

[Optional] Mount Vendor and Flash DFE [Optional - Not Recommended] or Encryption [Optional] (Read DFE & Encryption Guide above)
Reboot Enjoy!
[Optional] If you want to root, reboot once again to TWRP Recovery and flash Magisk then reboot to system and enjoy!
DIRTY INSTALL YOUR CUSTOM ROM
Note: Before you start flashing, keep in mind the ROM you dirty flashing MUST be the same with the one you have already installed.
1. Make a full nandroid backup, just in case something goes wrong. You can use TWRP to do that. (TWRP > Backup > Select everything) [Optional]
2. Remove all Magisk modules. [Optional]
3. Reboot to TWRP and Wipe Dalvik / ART Cache, System, System_Ext, Vendor, Cache.
4. Flash the ROM > GApps [Optional] > Magisk [Optional]
5. [Optional] Mount Vendor and Flash DFE [Optional - Not Recommended] or Encryption [Optional] (Read DFE & Encryption Guide above)
6. Reboot and Enjoy!
I've skipped some explanations, because if you are going to dirty flash, you already know for example how to boot to TWRP.
CLEAN INSTALL OFFICIAL STOCK MIUI ROM & RELOCK BOOTLOADER
Note: Some AMD Ryzen or Intel Systems may have problems to recognize your device in fastboot. [Read the AMD Ryzen/Intel Fastboot Fix Guide above]
1. Backup all your data to PC or to external SDCard, if it's possible. [All your data into Internal Storage will be lost]
2. Download the official Fastboot ROM and unzip it to your PC. [You can find it in my Collection]
3. Download Xiaomi Mi Flash Tool and run XiaomiMiFlash.exe.
4. Turn off you device and then boot in Fastboot mode by pressing Power Button + Volume Down (–) and keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.

Delete locksettings.db
This way, you will not have any lock method set, but added fingerprints will remain.
FIX FOR STUCK ON OREO FIRMWARE (SOFTBRICKED)
FIX (Read Carefully)
MAGISK ROOT
The easiest way to root your device is via Magisk, it should work in all ROMs, Stock and Customs.
Install Magisk:
1. Install latest TWRP Recovery. [Read the Install Custom Recovery Guide above]​2. Download the Magisk [You can find it in my Collection]​3. Reboot to TWRP Recovery by pressing Power Button + Volume Up (+) and flash it.​4. Reboot and check whether the Magisk app is installed. If it isn’t installed automatically, manually install the APK. [You can find it in my Collection]​Note#1: From Official TWRP Recovery 3.5.1 and onwards (and other recoveries based on that), Magisk.apk can be flashed as apk without the need of rename it to .zip. So you can simply flash the Magisk.apk in TWRP.​Manually Creation of Flashable Zip:​Download the latest Magisk APK and rename the Magisk.apk → Magisk.zip.​​Note#2: If your bank apps detect root, follow this Guide.​
Uninstall Magisk:
Flash the Uninstall.zip in TWRP Recovery and reboot. [You can find it my Collection]
If Magisk App isn’t uninstalled automatically, manually uninstall the app.
Manually creation of Flashable Uninstall Zip:
Download the latest Magisk APK and rename the Magisk.apk → uninstall.zip
Uninstall Magisk directly through the Magisk app. Simply press the Uninstall button.
Note: If your apps detect root, follow this Guide (or this) to pass SafetyNet and have certified Play Store. [YouTube Video Guide]
DISABLE FORCE ENCRYPTION (DFE) & ENCRYPTION
[You can find it in my Collection]
Disable Force Encryption
Disable Force Encryption (a.k.a DFE) is flashed during installation of a custom ROM to avoid the system encrypting /data partition when the devices boot for the first time.​Some ROMs are not encrypted by default and so is not necessary to flash DFE. However if your ROM comes with encryption by default you can always flash DFE after clean installation of ROM and always after every update or flash or you can use any custom recovery like OrangeFox, Pitchblack, Skyhawk Recovery Project which can automatic flash DFE after every flash.​I don't recommended to use DFE if you don't switch ROMs frequently and you are casual user. Beside the fact that if you lose your device your data are not protected, many people get in confusion while doing OTA or manually updates, which if the ROM is encrypted by default and flashed DFE and in next update you forget to flash DFE you will lock out from your data and you wil get into bootloop (use custom recoveries mentioned above to avoid that).​​
Encryption
Encrypted ROMs are recommended if you are stable and casual user of a ROM. Encryption have the benefit to protect your data, in case you lose your device for example. ​Always use the latest TWRP Recovery so you can be able to decrypt the data by filling the same lock screen password you have set in ROM.​Some ROMs are not encrypted by default but devs provide an Encryption.zip (script) which can encrypt the ROM. Same as DFE you need to flash it after clean installation of ROM and always after every update to stay encrypted and not get into bootloop. Unfortunatly there is not any custom recovery automatic doing that like with DFE, so you must be careful, avoid doing OTA updates and flash it every time you manually update a ROM.​

BATTERY TIPS
Xiaomi POCOPHONE F1 Battery Model: BM4E
Battery Replacment (Video)
Recommended Battery: NOHON for POCO F1 (AliExpress)
Advanced Guide
Simple Battery & Charging Tips
Improve your SOT
Battery Calibration
Method 1
Steps:
1. Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
5. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
6. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
Method 2
Notes: It won't dramatically extend battery life, but it will give your old battery at least 30 minutes additional run time.
Steps:
1. Get "GSam or Ampere" from the Google Play Store.
2. Launch the app and fully charge your phone. (Important: Only proceed with the calibration when the word "Full" appears in GSam or Ampere.)
3. While your phone is still connected to the cable reboot your phone to recovery mode, open file manager and navigate to "/data/system" and delete "batterystats.bin," "batterystats-checkin.bin," and "batterystats-daily.xml."
4. Reboot your phone (while it is still plugged in) and charge it until it reads "full" on GSam or Ampere.
5. Unplug the cable and use your phone normally until it shuts down (0 percent )
6. Charge your phone to 100% while it is turned off.
7. Boot into os and plug in your phone and charge it until it says "full" on the GSam or Ampere.
8. Unplug and have fun!
Battery Capacity Health
Notes:
1) Before checking the battery health, charge the device to 100%.
2) Check charge counter values and consider first 4 digits from left as your battery capacity in mAh. And check charge counter. (Charge counter/level)*100 is the battery capacity.
To find battery capacity in Windows:
Enable Developer options in your device.
Enable USB Debugging in your device.
Conect your device to PC and give permissions.
Open Minimal ADB (run cmd.exe) or Platform tools.
Type "adb shell dumpsys battery" command in Minimal ADB or Platform tools.
To find battery capacity in Android (Terminal) - Root needed:
Download an android terminal app like Termux,
Open terminal and type: cat/sys/class/power_supply/battery/charge_full
Overheating
Following reasons will lead to device heating issue:
During the initial setup after purchase or when restoring data.
Downloading large files.
Using apps that require more power or using apps for extended periods such as:
Playing high-quality games for long time.
Recording videos for extended periods.
Streaming videos while using the maximum brightness setting.
Using the Screen Mirroring / Smart View feature (connecting mobile to a TV).
While multitasking or when running many apps in the background i.e:
Using Multi window.
Updating or installing apps while recording videos.
Downloading large files during a video call.
Recording videos while using a navigation app.
Large amount of data for syncing with the cloud, email, or other accounts.
Exposing device under sunlight when temperature is high around you.
Extensive usage of mobile hotspot and tethering feature.
Using device in areas with weak signals or no reception or in roaming network.
Charging the battery with a damaged / unapproved USB cable.
Device's multipurpose jack is damaged or exposed to foreign materials, such as liquid, dust, metal powder, and pencil lead.
Solution:
Turn off Wi-fi, GPS , bluetooth and other connectivity options when not in use by dragging the notification panel.
Decrease screen brightness.
Close background running applications.
Too many applications installed in device may result in device heating since their corresponding process will keep on running in background. It is advised to uninstall un-necessary apps if not using them.
Avoid using apps like GPS, data dependent apps or graphic intensive games for longer duration since they require more energy to function, causing device to heat.
It is advised not to use device while charging as it may cause the device to over heat.
General:
DO:
Use manual brightness or dim the screen.
Turn off notifications for apps you don't use. Better still, delete/disable the apps entirely if you don't need them.
Enable battery or power saving mode when you want to extend your battery life.
Use the power adapter that came with your phone. Other chargers can charge slowly/faster but they can also damage your phone or battery.
Turn off bluetooth, location tracking, and Wi-Fi (unless you are actively using it)
Turn off print services from bluetooth connection preferences.
Avoid extremes of heat and cold. If your phone gets very hot or cold it can strain the battery and shorten it's lifespan.
DON'T:
Have Bluetooth or Wi-Fi turned on constantly.
Leave apps running in the background. Instead restrict background usage off apps that you don't need running.
Push email means your device is always listening for new email which drains alot of battery.
Drain your phone battery all the way to 0% or charging it all the way to 100%. Keep it between 20% - 90% for longer battery lifespan.
The more advanced the graphics and animations are (games, videos, photos, animations), the harder the processor and graphics chip in your smartphone have to work. More activity means more battery use.

ShutUP10++ , Privacy.Sexy: Disable major tracking features of Windows.
General:
Always prefer Open Source or well popular Programs, Apps, ROMs, Kernels & Stuff.
Open Source doesn't mean it's 100% safe but it's unlikely to have something suspicious, since you and other users can check the code in GitHub or in any other code hosting platform the "stuff" is hosted. You can also find and use FOSS apps at F-Droid or at Droid-ify (Recommended).
Prefer ROMs & Kernels with SELinux Enforcing. You can find informations here.
Always download and install Apps, Programs, ROMs & Stuff from official sources and do not use redirection links from different sites. Google is your friend to find the official source of the stuff you want.
Always check the permissions an app requires, before download and install it to your device. If an app ask for permissions which has nothing to do with the app functionality then it's should be reconsider or ask the developer why these permissions needed.
You can also check if the app includes trackers and ads with εxodus.
If you want to avoid Google and Play Store (De-Google), you can choose a ROM without GApps preinstalled like LineageOS and use Droid-ify client which is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device. Note that not all apps from Play Store will be available in Droid-ify or F-Droid. Only Open Source projects. You can find alternatives though.
Alternative you can use LineageOS for microG or any ROM which support signature spoofing and can support microG and use Aurora Store.
For Windows use the default Windows Defender & Malwarebytes to scan your files whenever you want (Prefered before open or install them). Also use the addon/extension uBlock Origin in your Browser. These should be enough for normal users. You can also use the tool ShutUP10++ or Privacy.Sexy to disable major tracking features of Windows.
For Android Do not use any antivirus - antimalware since it's useless, just check what apps and from where you installing.
Always verify the source of addons/extensions in your browser. Avoid installing random and unpopular addons/extensions. Keep it minimal and clean, so browser can be fast and safe, no need bunch of extensions.
If you are using VPN, always check the terms and rules of the provider. Avoid random VPN Services.
Recommended VPN Services.
Using a VPN will not keep your browsing habits anonymous, nor will it add additional security to non-secure (HTTP) traffic.
Recommended is to encrypt your data/files always before uploading them to cloud with tools like Cryptomator.
Always use unique and strong passwords for each of your accounts.
Use awarded open source Password Managers like KeePass or KeePassXC for Desktop and KeePassDX for Android to manage your passwords and have them with you safe, encrypted and secure. Must be noted you can use the same database file between these programs.
Always enable 2 Step Authentication wherever is available for your accounts.
You can use apps like Aegis Authenticator.
Do not open or click on links attached in unknown emails or SMS you may get. Always check the address of the email or the number of SMS and verify it's legit from the official source.
Create and use "burned" email for accounts/sites you have concerns but you definitely want to try them. Do not use your personal or business email. You can also create and use email aliases of your email with SimpleLogin which is open source and awesome service.

Try to do factory reset (firstly save all your personal data to PC or to external SDCard). 12.0.2 and general all the latest miui updates are full of bugs and slow down your device. Also the chances to get new android version in miui are very low. I will not talk about security and tracking.
I recommended you to move away from miui and use a custom rom of your choice. :fingers-crossed:

Awesome thread, everything at one place. Thanks man.

You have gathered so much collective information at one place. It will be helpful if we found which Roms are from Pixel Ports and supports Google photos free unlimited high quality storage.

OP, this is a godsend! Thank you so so much. Any idea what settings I should be using for the most "pixel like" photos on parrots gcam?

I don't know but you can try the latest port of Parrot or use Sanitys or BSG ports. Try and find out which is the best for you You can also try to ask on Photography thread.

Yes new pixel phones will not have this advantage. (New pixel phones which ain't even launched yet)
But we have some roms which are ported from existing pixel phones like Pixel 3 and Pixel 4.
I got to know that Awaken OS based on Android 11 is detecting as Pixel 4 in Google photos. I'm not sure, I personally didn't install it yet.
I'm sure about some Roms and Ports like Pixel Rom and Pixel 4 xl ports are obviously detecting as Pixel 4 and they are enjoying new Google Assistant and Google One features as well.

I personally use Pixel Experience the Plus Edition. It's stable and ready out of the box.
However there a lot of nice ROMs, you check them in my collection and decide which fit for you.

Well the thing is we don't know yet if POCO F1 detecting as Pixel 4 in Google Security is enough to bypass and trick Google to have unlimited storage. We need to wait till June 1st, 2021 which this change will take place. Until then, the storage remain unlimited.

Any Pixel Experience ROM or GSI for the A8 ?

Hello everyone, I tried most of the ROMS from here like feusionX, Qdroid, TreeUI and some of the old ones.
I liked the most of them, but what I am looking for is a ROM that has the Pixel experience feeling with all the features.
is it possible ?
I tried to use this method to use project treble on the phone but I wasn't lucky to flash any GSI.
every GSI I try It ends up in a boot loop.
what am doing wrong here?
any suggestion ?

Hello!!!
Look... Custom Rom for our phone is hard to find one that works (I say there's none)...
There's a Pixel Experience GSI that I was using it... https://github.com/ponces/treble_build_pe/releases
In this post you have the normal Pixel Experience and Pixel Experience Plus.
Difference??? Plus has some more modifications
I recommend using Vendor Quack...
[SAR][Vendor][10][A530F/A530W/A730F] Vendor Quack V2.5 For Galaxy A8/A8+ 2018
I noticed three lines in the build.prop ro.vendor.build.fingerprint=samsung/a7y18ltexx/a7y18lte:10/QP1A.190711.020/A750FNXXS4CTH3:user/release-keys ro.vendor.build.version.incremental=A750FNXXS4CTH3 ro.product.vendor.model=SM-A750FN Could...
forum.xda-developers.com
There is no secret to installation, I believe you already have TWRP or OrangeFox installed...
First of all don't forget to backup your important files
1. Download Vendor Quack and Gsi in Arm64-AB-Vndklite format
2. Extract just the GSI so we can get the image of it (Winrar or 7zip are great apps that do the extraction work)
3. Restart in Recovery
4. Follow the same steps in the post https://forum.xda-developers.com/t/...-guide-for-galaxy-a8-2018-18-04-2019.3894881/
and then continue with my steps
5. Clean up Dalvik, System, Vendor, Data, Internal Storage and Cache partitions
6. Pass the GSI and the vendor to the device's internal memory
7. Install Vendor Quack
8. Now Install GSI
9. Install Magisk if you use
10. Reboot and enjoy your PE
Notes
Pixel Experience does not need install GApps
Bugs...
1. The GSI can crash hard sometimes and you have to force reboot on it.
2. If the above bug happens, the rom may come back buggy from reboot and you have to reinstall it again. (It's a little rare this is worth mentioning)
(Sorry my English)

How To Guide [OUTDATED - PLEASE USE UNOFFICIAL LINEAGEOS INSTEAD] Installing a GSI on Samsung M12/A12.

I am deleting this guide since M12 will soon recieve an unofficial build of LineageOS 19.1. Don't ask when, as I'm not the lead developer but I helped with it

Update 1: I figured out how to make script run on boot. Instructions revised. If you followed earlier check them again
Update 2: Magisk 24.1 is now stable. Instructions revised.
Update 3: I contacted phh and he implemented the script inside his trebleapp. Instructions revised and modified trebleapp is attached. NOTE: GSIs newer than 7/Feb/2022 will include this workaround by default.
Update 4: This guide is now unnecessary now that unofficial LineageOS is very close to release

Achievement unlocked: flashed GSI with FBE enabled! ​

In short, I've successfully done flashing of @phhusson's latest version of Android 12 GSI (which is v402 as of today). To do this, I needed to modify the multidisabler script so it won't disable FBE, format the userdata using the stock recovery, flash TWRP, resize tmpfs to proper size, push GSI image into tmpfs and flash it using TWRP. I used the securized image with vndklite variant, since there was no securized images for regular vndk releases (but it seemed that vndk was working better for me, at least I have no USB connection anymore where with VNDK I was able to have USB debugging). Maybe I'll try re-flashing it once I'll patch the regular images and securize them (since I'm on *nix, I can just mount them and modify their contents) and take an approach of finding how Samsung ROMs are working OK. For now, I need to take a break from all bootloops I had in the process of FBE flashing .
Anyway, the goal of this experiment was to use GSI ROMs as a daily driver and having FBE disabled could otherwise cause a serious problem on device loss.
So, onto the list what's been tested (that wasn't noted before):
Screen locking – it seems that the workaround for the screen is not applied before unlocking the phone, probably because the app is not running yet. This might work with the script used as postfs module.
EDIT: I've found some notes in the Magisk documentation that both post-fs data and late_start services are run after data is decrypted, which basically means applying this workaround using Magisk seems to be pointless for now (maybe not after PPH app will stop providing the workaround)... Probably the best option would be patching the ROM itself, either with flashable ZIPs or directly before flashing it (most GSIs can be mounted under Linux and tweaked).
Adaptive brightness – not working, since all virtual sensors are not working for now. Might be easy to fix through as I've found some stuff in the official ROM that I had an idea to experiment with putting them into GSIs (as a Magisk module, to avoid a breakage).
USB – as I said, a data transfer via USB is not working for me for some reason. It worked for me once I had VNDK Android 12 GSI installed (same version).
Booting with stock kernel – I had some successful attempts doing that, but it further was a cause of a bootloop, at least once I had installed Magisk. Therefore, I'll recommend patching the Magisk the way as in tutorial (after patching the kernel) to have everything working for now.
For people who wants to play with stock images but don't know how: you can use simg2img, lpunpack and Linux to extract and mount the official ROM image in approach of finding there some tips like in initrc services why some stuff is working fine on Samsung while it doesn't on GSIs. Maybe I would tinker with it a bit, trying to export a few services and libraries in an approach to create a Magisk module with all stuff needed to have a fully functional GSI, but I'm tired of modding for now, especially when this is my first Samsung phone I had to deal with.
Edit: Typo fixes, added additional text formatting.

Amazing work. If you need testers feel free to PM me. As a sidenote, poking in sysfs led me to believe that android is sending the info needed to read the proximity but the kernel is sending garbage which gets interpreted as the sensor not being triggered. Also phh should have added the workaround into his trebleapp starting from phh AOSP 12 v401, so aside from installing magisk no post install workarounds should be needed.
Attached is a photo of what cmd_result reads when a whatsapp voice message is played which reads proximity to play the message in the earpiece and turn screen off when proximity is triggered

Unfortunately, the commit was reverted as of master branch, so we should prepare for it to stop to work unless phh will work on it before releasing an another version. Also I wrote that the workaround didn't seem to apply itself before unlocking the phone (FBE encrypted) the first time and therefore decrypting sensitive data after boot. For now this makes it an requirement when using PHH app to unlock the phone before it sleeps so the touch is going to be responsive.
Anyway, it seems that even Magisk (v24.1) is not capable of running the services before data is decrypted, so now I have no idea how to bypass that in other way than patching the ROM itself and creating the `initrc` service... Anyway, this is also a hint that what samsung is doing starts before basically everything, so no APK file nor script is going to really fix it since they are meant to start after data is decrypted...

I guess for now we have two options:
A: Build custom kernel/vendor specifically for GSIs that correctly reports sensors as GSIs expect them to
B: Fix GSI issues through Magisk services implementing various workarounds in scripts. (an example is the touchscreen sleep/wake issue)

Also that's interesting those virtual sensors are still present, I personally thought that Samsung made it the way there's an virtual device create as on Linux and there's their proprietary software running somewhere in the system that uses the camera as an input and calculates it to provide the data... On the other hand, when I think about that logic, even some (if not all) virtual devices on Linux (e.g. v4l2loopback) needs to have their module loaded with the kernel to work. I'm glad at least there's no need to reinvent the wheel and no one really needs to recreate the entire algorithm for it if it's going to be in the kernel sources...

I feel like the B option is worse than patching the GSI ROMs, either via flashable ZIPs or on your own... This is because I couldn't find anything in docs that would let me run services before /data is going to be decrypted... Personally, I've made myself a such service using the statically-compiled Linux ARM binary (non-NDK, using GNU libs – yes, it is still runnable on Android as well) – it applies the workaround for now both when screen is turned on and off (I had no idea on which event it should really run, so I made it to run on both just to be safe) by watching the file changes based on (AFAIK) filesystem events – so it has a major advantage over your script, as it won't run in endless loop, yet watch the file responsible for brightness to change and then do its job. But even with that, TSP doesn't seem to make touch available immediately and it is still expected to be revived after 1-2 seconds.
Also, as of the methods of applying these workarounds, the other way could be modifying the ramdisk (maybe with the help of Magisk, which I believe has documented how it's actually doing it itself and how others could modify the root and init as Magisk does to load files before the OS will properly initalize itself. Yet I don't like an idea of messing myself with the boot partition, at least for now...

Debug info: I tried flashing stock to grab logs from the touchscreen driver. The logs attached here do not appear at all on an unpatched GSI (I.E flashing the GSI as is without any touch workaround).

Hi, I installed LineageOS 18.1 GSI on my M127F. I want to share my guide to installing this GSI.
Code:
DISCLAIMER:
By following this guide you accept that you
may do irreversible damage to your phone.
If something breaks the responsibility is
yours only. If you want stable software that
is guaranteed to work 100% don't follow
this guide.
I assume you are running a fully stock system and and locked bootloader and firmware U3/U4.
Installing TWRP and custom kernel
Enable Developer Options by tapping on software information > build number 7 times
Enter developer options then toggle OEM Unlocking on.
Power off your phone.
Hold Vol Up + Vol Down then plug in your phone to enter download mode
THIS WILL ERASE ALL YOUR DATA AND VOID YOUR WARRANTY. Follow on screen instructions to unlock your bootloader. THIS WILL ERASE ALL YOUR DATA AND VOID YOUR WARRANTY
After this you want to download and install attached Orangefox recovery using odin. After odin is done flashing enter recovery
Format data (not wipe) in recovery
Enter terminal and type multidisabler twice
Reboot to system and verify that under security encryption is disabled
Download TWRP and custom kernel for your phone
Reboot into recovery and locate the downloaded twrp image
Select recovery.
Reboot into recovery
Install kernel, then wipe cache and reboot. You should now see that it is complaining about some internal issue. This is normal.
Installing the GSI
Download your favorite ROM from the list provided below. You want to install an arm64 a/b image.
Extract the image file
Reboot to recovery.
Select install then install image
Locate the GSI image
Select install system
After that is done return to recovery and select factory reset.
Reboot then do setup (if applicable) then download attached magisk and phh trebleapp. If your phone is stuck on bootanimation check under to fix it.
IMPORTANT: DO NOT LET THE SCREEN TURN OFF OR YOU WILL HAVE TO REBOOT TO MAKE TOUCH WORK AGAIN.
Install attached magisk
Open magisk and click on install then direct install
Download and install the attached phh-treble app apk.
Touch should now work. Enjoy your GSI.
Extras
Magisk 24.1
Open Magisk
Go to settings
Update Magisk Manager app to version 24.1
Relaunch Magisk then install magisk
Choose direct instal
Migrating to patched trebleapp
Download and install attached trebleapp
Open your root file manager
go to /data/adb/service.d
Delete the script you added earlier
Tips in case things don't work
In case after rebooting to the GSI the phone bootloops:
Download stock image from wherever you download your firmware (I use a python program called samloader)
Extract the AP of the downloaded firmware
Find userdata.img.lz4 and create a .tar archive only containing this file
Reboot to download mode
In odin select AP then locate the newly created .tar archive Then click on flash
Reboot
Continue from step 7 under the "Installing the GSI" portion of the guide
To revive the touchscreen using ADB:
In case you didn't grant adb root access but installed magisk, run adb shell then su. A root access for the app shell will appear. Grant root permission
Plug in phone to a computer with ADB
adb shell
su
cat /sys/class/sec/tsp/cmd_result
echo check_connection > /sys/class/sec/tsp/cmd
What works:
Boots
RIL
Fingerprint
Main rear camera
Front camera
Sleep/Wake (workaround in steps above, may need to sleep wake several times before it works)
WiFi
Flashlight
Rotation
Magisk 24
90Hz (M12 only. A12 doesn't have 90Hz refresh rate)
LineageOS 18.1
LineageOS 19
CAOS (GApps variant available)
phh AOSP 11 v313
phh AOSP 12 v400h
Untested
GPS
Flashing GApps. (I use fdroid and aurora store on LineageOS and CAOS has built in GApps)
USB-OTG
A127F
M127G
If I didn't list it under broken or working I didn't try it or forgot to test it.
Broken
Double tap to wake. Touchscreen turns off and I have no idea how to keep it alive while lcd is off
MTP
Virtual Proximity. Screen will stay on in phone calls and WhatsApp will always play voice messages through speaker
Flashlight brightness. Flashlight will always stay on weakest brightness with no way to adjust.
Adaptive refresh. The framerate you set in phh addons is what you get. Be prepared for slightly reduced battery.
You tell me (even though I probably don't have the solution)
Bugs
You may need to wait a little bit before touchscreen responds or sleep/wake several times before screen responds after turning the screen off

Great guide.
Well done

Thanks for the great guide. Unfortunately, I don't know how to resize tmpfs. Can anybody tell me how to do that? I only have 4 GB or less on my Samsung Galaxy A12 with 64 GB of Storage (it should have, it only shows something like 3 or 4 gigabytes like I mentioned)

You don't have to resize TMPFS if you don't want to have FBE encryption or have the external SD card (you can use microSD for flashing, which might be a better choice if you need to flash a larger devices). Also you can't resize TMPFS to 64 GB, it uses your RAM to store regular data instead of storage (this is basically the concept of TMPFS). What I was mentioning is that /data won't work under FBE and custom recoveries for now, so you need to use your RAM instead if you don't have any external storage device to save images somewhere via ADB.
As of resizing the TMPFS, you should be able to find some Linux tutorial how to do that, on Android this is works basically the same (even on both Linux and Android you have /tmp directory with TMPFS by default).
Anyway, I've decided to share some stuff that you may need for that. Here's the multidisabler script I was using for flashing GSIs with FBE encryption preserved. I was also working on the native binary that would work as the workaround for the touchscreen so it can be used instead of the script. The advantages are that it actually listens to filesystem events and therefore does not need to read file in loop in order to get the information if brightness has changed. Maybe I'll share it with you once I find it to be ready, right now I'll just share my multidisabler script with patches.
BTW, I've tested LineageOS GSIs (both 11 and 12) and noticed they behave completely different, no matter of variant (the USB actually uses some driver, which is not fully compatible with M12 but close enough to provide basic communication through ADB). I guess pphusson just changed something and now these drivers aren't applied by default, yet I think I've noticed the issues with Bluetooth's HSP/HFP profiles which as I remember was not the case with latest stable pphusson's vanilla Android 12 GSIs. Now I just hope these problems are going to be resolved in the next builds of Android's GSIs with phhusson's patches and with the knowledge that MTP just worked fine on TWRP I used, there's a little hope that we will gain the proper combination of drivers/firmware to have both USB and Bluetooth functional at the same time someday.
I've also approached patching the kernel under newer kernel base 4.19.112, yet I gave up on properly resolving its conflicts. I may work on that as well in order to patch some vulnerabilities, with a hope that I'll succeed updating kernel as closest to the latest patch as possible. The 4.19.112 is going to be just a test if Samsung is capable of actually booting from it and if I may be able to use git with common human logic and my limited programming skills to actually patch it the way it would do so (without much understanding about the code itself, yet basic knowledge about C syntax). For now I've only succeed reproducing the upstream Linux kernel commit structure from 4.19.111, with a single additional commit for Samsung changes and another one for physwizz ones.

can anyone guide me how to unlock bootloader on Samsung Galaxy M12G ?

@SB3P Thanks so much. Sorry for my late reply, but thank you!

If you would see the *untested* section at the initial post of this thread, it is unknown whetever this works or not for M127G phones (if it bootloops it might not work at all). Anyway, here's how I did it on M127F (at least how I remember this):
1. I did steps from 1-6, I believe I skipped 7 since I was aware it will mess something up with the data partition.
2. I modified the multidisabler script and pushed it to my phone via the ADB (to TMPFS). You can find this script pushed as xz compressed file. Before executing multidisabler script I have done a backup of the recovery and system partitions (using dd tool) which I am going to reflash later.
3. I rebooted to download mode and flashed TWRP image.
4. After TWRP ended flashing, I booted into the recovery. I flashed the physwizz kernel and then my own GSI image as it was described in the instructions at the initial post. Just remember that /data partition is not functional with FBE and TWRP so you need to push your images somewhere else like microSD card or TMPFS partition. OTG might work here as well, this is something I haven't tested yet through...
5. Once you are done with flashing you need to restore the original recovery partition via the download mode. TWRP won't boot the GSIs with FBE encryption enabled actually it does boot now for me, yet I still recommend switching to stock recovery if your phone bootloops or you need to format/wipe userdata partition. You can then safely format your /data partition with the stock recovery.

LineageOS is not only GSI available, I think someone might still find it useful if they want to flash another ROMs. Also Phhuson's GSI also contains some features that unofficial GSI release don't have (i.e. flashlight control in Phhusson's app), so they still might be useful for someone.
This is why I think it is better to not close this thread and maybe revive original guide.

I haven't said GSI are better, I personally use this unofficial LineageOS build. But what I've said, GSI brings much more variety of picking the OS you can install. Even Linux can be installed on phones nowadays using GSI with only Halium-patched kernel as an requirement. This is why I think leaving this tutorial archived (no updates, interest on fixing bugs etc.) is better than removing it.
