[Guide] How to install a GSI treble rom on our Daisy - Updated [5.11.18] - More easy.

This guide lets you install any GSI treble roms on our Daisy.
Read carefully and go step by step!
Update: Since Havoc OS doesn´t need permissive Kernel, I just installed the latest stock rom (9.6.9.0), flashed Havoc, set everything up and ended with sh...t... Camera´s not working, Opera freezes, everything sucks. It was a waste of time... So it´s still the situation:
If you want to use a custom GSI-Rom Only use this combination: Stock rom before flashing GSI: 9.6.4.0 and Kernel: Unofficial TWRP by Yshalsager - this combination works like a charm​
Let´s get started: Be sure you are on Stock 9.6.4.0 (july security patch) if not, your wifi will not work in treble rom!
1) Download latest AB arm 64 gsi build. - ONLY ARM 64 AB GSI WILL WORK!
2) If you don´t have fastboot and adb download it from here: https://forum.xda-developers.com/sho....php?t=2588979 and install it!
3) Extract gsi64-ab-image to adb folder and rename it to system.img
4.a) Windows 7: right klick on white space in your adb-folder: open command prompt here
4.b) Windows 10: open command prompt as admin and navigate to your adb folder
5.) Power off your Smartphone and press pwr and vol- together -> your screen will show FASTBOOT - connect your phone to your PC
6.) type in your command prompt
Code:
fastboot oem unlock
Important: this will format your SD - All data will be lost If you perform that step! -> Backup before!​7.) Phone will reboot, erase data and boot up. Power off again after boot up. Power + vol- to enter fastboot.
Now you have to decide: If you want to use Android 9 roms and TWRP together, you have to decrypt your data - else TWRP will not be able to read data! If you don´t care continue on step 11​
8.) Download a patched_boot.img and place it in your fastboot folder - since only 9.6.4.0 works without bugs, you have to choose the patched 9.6.4.0 boot
9)
Code:
fastboot boot patched_boot.img
10) Connect to internet and update Magisk manager, download a root explorer - you could use this and go to
/vendor/etc/ and open the file fstab.qcom in editor​replace the text "forceencryption=footer with "encryptable=footer" and reboot to bootloader​
11) Download this, rename it to boot.img and copy it to your fastboot folder
Code:
fastboot flash boot boot.img
12) Install official TWRP
13) After installing official TWRP reboot to TWRP agian and go to "wipe" -> "format data" and type "yes". Reboot to bootloader
14.) Download your GSI AB Image and place it in your fastboot folder
Code:
fastboot flash system [imagename].img
If you want, you can boot now to twrp and install magisk and/or gapps whatever - everything will work. Else you boot up your new system - Sometimes your GSI-rom will not boot up without a rooted kernel.
So if you stay in bootloop, just install magisk.zip!
Violla - Now you have a treble gsi rom on your Mi A2 Lite!

theres working twrp out for daisy, does this change anything refering to your first line:
"1) Download latest AB arm 64 gsi build. I would always use the gappsed version - twrp still not running for daisy... - ONLY ARM 64 AB GSI WILL WORK!"

thanks for the guide!
i really want to try this but im not sure which rom fully works. Also i'm not sure to do this without TWRP cause i'd like to have a complete backup of my device.

i'm in 9.6.9 version now with locked bootloader and unrooted
any suggests for me to try this rom

No problem - meanwhile there´s a official twrp here - and you can still use this guide
If you want to flash havoc 2.0 - I think it´s the best rom on earth , you will need to change your kernel to permissive that it will boot. To do that, read the thread there´s a vivid discussion how to do it...

If you like to have more features and/or pie (Android 9), then I would suggest to flash a custom gsi rom. If you can live with stock, I wouldn´t touch it.

i want havoc OS but as i understand i can't use the fastboot method because i need the permissive fix, which only can be installed via TWRP, correct?
i would prefer fastboot over TWRP because all the problems with sdcard reading, encrypting etc.

Hi,
there are so many reasons for havoc not to boot... and so less to boot...
BUT... If you won´t mind to use an unencrypted phone or no twrp, you can use (as I think) the best Android OS, havoc.
So think about, what is more important for you: TWRP or encryption.
1. With encryption: (Quite easy)
a) Go to stock 9.6.4.0 - July patch with mi flash and choose clean all (yes you will loose all your data -> back up everything) - Important: don´t install any ota after that!​b) Download latest havoc and place it in your fastboot folder​c) Download this TWRP and place it in your fastboot folder - you need this as Kernel​d) As lazy person, I would rename the havoc file to havoc.img and the twrp file to twrp.img​e) copy userdata.bin from stock to fastboot​
Code:
fastboot flash system havoc.img
Code:
fastboot flash boot twrp.img
Code:
fastboot flash userdata userdata.bin
Code:
fastboot reboot
Wait and wait and wait and violla, you have havoc!
f) Gapps: download gapps, copy it to your fastboot folder and rename it to gapps.zip. Boot to recovery - twrp will not be able to read your data -> skip and allow modifications​
Code:
adb push ./gapps.zip /sdcard
- Now you see gapps in your zip and you can install it!
g) Magisk: for magisk you need to download my patched twrp and place it in your fastboot folder​
Code:
fastboot boot patched_twrp.img
- After booting up, you can go to magisk manager (yes: upgrade first etc.... and install magisk using the "direct method"
2. If you want to remove encryption - then you can use twrp fully, use this guide: here
Important: If you use another stock rom than 9.6.4.0 or do an ota, you will loose wifi!​after doing all the steps:​
Code:
fastboot flash system havoc.img
- that´s it!
Now you can use havoc

No idea why you're useless taking pot-shots at other people, especially when you keep spreading lies about stock roms because you use a broken recovery. But have it your way.
Just keeping telling people to use a broken/untested recovery and bricking their phones, that forces them to reflash boot images. Can't wait until the bricks pile up.
I'm done with this website.

If you would read, you would have noticed, that that broken and untested recovery is used as kernel, becouse it works great as kernel for gsi roms. Within the process it will be upgreaded by official twrp.
I spend a lot time, testing how to install custom roms on this phone, becouse I don't like like stock and I share my experience with others. Noone will break his phone with this! Perhaps you can try before complaining.

Lol, this site has gone way down hill... It's almost a joke now.
So many people asking for the 'easy' way and want answers to easily searchable questions. Sooo many multiple posts, and people not wanting to do the research themselves. How many threads need to be created on bricked devices because you didn't heed the warnings or follow the directions...
I wonder if xda even cares? This place use to be a great tool for the ones who like to tinker.
There are definitely a few folks keeping the spirit alive, but so many unnecessary posts - like what I'm writing right now...
Anyway thanks to anyone who puts time and effort for the greater good, we should all understand that tinkering with our devices can potentially have adverse effects.

Thanks for this noob friendly guide! a massive thanks! But hotspot still not working. Haven't tried the gcam but the stock camera is working but has no portrait and other features. The havoc os 2.0 looks snappy and buggy. Ill try other treble roms in few days
Any suggestions?

You're welcome. Don't have problems with bugs and havoc 2.0... Interesting to test would be arrow pie! Benzo had problems with camera and flashlight... All the 8.1 can't handle the notch and overlay!

Android 11 Custom Rom for the Xperia XZs

Hi can anyone make an android 11 custom rom(Pixel experience/ evolution x/ havoc os) for this phone pls? Thank You.

Yes, you can:
go to https://forum.xda-developers.com/t/10-0-project-treble-for-xperia-xzs-2020-03-18.3976367/ then download the zip file and flash vendor.img and boot.img (steps provided in the zip).
then download any android 11 custom rom GSI having arm64 and AB or A/B NOT A only or B only and flash it with fastboot command:
Code:
fastboot flash system <GSI filename>.img
You will need to download and install adb and fastboot tools from google to get the above code working. Also have a bit of patience while first boot your custom ROM after flashing, I will take some time for it to boot up
I have tried:
- Pixel Experience Plus and non-Plus
- Corvus OS
- Havoc OS
Link to official GSI ROMs supporting Project treble devices(This device is included): https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

i get "Invalid sparse file format at header magic"
and my phone won't boot HELP

How did Havoc OS work for you?
I am always afraid to flash something that doesn't say precisely that it is for the XZs. But I should mainly be concerned about the kernel, right? If the image is wrong it just won't boot? But the kernel can brick it. Is my assumption correct?
Thanks to everyone who help us illiterates out...
Cordially,
Martin Book

Just follow the guide in the xda thread link I gave, you can use and android 11 GSI ARM64 AB image and you will be fine as far as my testing goes...
Just flash the vendor.img, boot.img and after that find a GSI image with ARM64 AND AB(The file name might use some other code name for this so just make sure the one you download has AB partition).
Note: Android 12 won't work and also daily use is not recommended

Guide to Install GApps and Magisk on Custom ROMs for Nokia 7.2

While I was trying to install GApps for Lineage OS 18.1 on my Nokia 7.2, I always lost my wi-fi. This is apparently due to flashing TWRP as boot image, which replaces the stock boot messing with wi-fi as the boot image has thee kernel.
Although, I did figure it out, it took me three days to get a proper solution from multiple sources. Here, I will explain how to install Lineage OS 18.1 on Nokia 7.2 with Gapps and Magisk. This can be applied to other ROMs as well. I am assuming you are on stock firmware.
Requirements:
Any custom ROM without GApps
vbmeta file
vendor image
Gapps zip file of your choice
platform-tools
twrp image
magisk file
payload dumper tool
Preperation:
The wifi stops working because we change the boot image. To prevent this, we must flash the boot image of the rom after we are done with our work with TWRP
For this, we ,ust get the boot image for the ROM. As this is not available readily, we must extract it from the ROM zip
Install latest python on your pc
Get the payload dumper tool from the link given below. Extract the contents into the root directory of python. It should be in C:\Users\USER-NAME\AppData\Local\Programs\Python\Python <version number>
Extract the ROM zip into any folder. Copy the payload.bin file and paste it in the folder where you put the payload dumper tool
Open a command prompt in the python root folder and type
Code:
python -m pip install -r requirements.txt
Then type
Code:
python payload_dumper.py payload.bin
After it finishes, go to the folder named Output inside the python folder. Here there will be a file named boot.bin. Rename this as lineage_boot.bin and paste it into the platform tools folder
Installation:
Download the twrp image, rename it to twrp.img and place it in the platform-tools folder. Connect your phone to the computer, switch on usb debugging on your phone.
Open command shell in the platform-tools folder and type
Code:
adb reboot bootloader
. In the bootloader, type
Code:
fastboot flash boot_b twrp.img
.
Next, type
Code:
fastboot --set-active=b
and then reboot to recovery using volume buttons and selecting using power button
In TWRP swipe to allow modifications. Copy your ROM and vendor image files to your SD Card. Now, click wipe, format data and type yes. Go back to home screen and the press install. Select your ROM file and install it. Sometimes it is required to flash vendor image. In that case flash that too. This step is required for Lineage OS 18.1
Now on the twrp home screen, tap on reboot. At the bottom, the current slot should be B. Tap slot A. THis changes the active slot to A. Now go back and tap on bootloader, this should boot you to the bootloader.
Take your vbmeta.img file and place it in the platform tools folder. Now, while in the bootloader mode, type,
Code:
fastboot flash vbmeta_a --disable-verity --disable-verification vbmeta.img
Next type
Code:
fastboot flash boot_a twrp.img
and boot to recovery using volume buttons
Now, press install in TWRP and select install and install the GApps file and reboot to bootloader
Next, in the bootloader type
Code:
fastboot flash boot_a lineage_boot.img
. Now start your phone. You should have lineage os with GApps
Installing Magisk:
Copy the lineage_boot.img into your phone. Download magisk.apk file from the link given below
Install the magisk app and open it. If it asks for additional setup select no. Beside the magisk option select install. Under options, if Recovery Mode is selected, deselect it and click next.
Now click on Select and patch a file under method. Select the lineage_boot.img
The patched image will be saved in downloads folder. Rename this file to lineage_magisk.img and copy it to the platform tools folder on your computer. Reboot your phone to bootloader mode
On your computer in the command window opened in the platform tools folder, type,
Code:
fastboot flash boot lineage_magisk.img
Reboot and you will have a rooted lineage os with GApps
Files:
Lineage OS 18.1 and vbmeta.img
TWRP
vendor
NikGApps
Payload Dumper tool
platform tools
Magisk
Guides that I Followed:
Extracting boot.img from ROM zip
Installing magisk using patched boot image

Hi @Ujwal2000 thanks for the guide.
I am using the stock android 10 rom and magisk patch method.
This also leads to non working wifi and magisk does not recognize that its installed.
Which steps of your guide apply to the stock rom?
i do not need gapps nor twrp I guess I only wanted to root the stock rom with magisk.

For stock, use this guide. They maintain a repository if patched boot images

@Ujwal2000 , can you please look at my posting here? Thank you.

after fallowing the steps(except installing lineageOS with twrp flash everything was encrypted even tough i have the bootloader unlocked, managed to install it via adb sideload) the wifi doesnt work at all. When i try to turn it on is switches off on its own. Do anyone know a fix?

i had problem with latest version of python (3.10), version 3.7 was working for me

Oukitel k15 pro

Hey does anyone know about a custom recovery for oukitel k15 pro? Or can I get away with using the stock recovery and a patched magisk file? If so does anyone have a up to date link.
Also would lineage work on this phone.
Thanks in advance

There is no custom recovery. Oukitel haven't even posted the official Android 11 ROM on their Download Center website yet, even though I sent them a message about it a week or two ago.
I bought the phone, but haven't gotten it yet.
I wouldn' t do anything to modify the ROM without having the official ROM from Oukitel to unbrick the phone just in case something goes wrong with Magisk or something.
There are ways to extract the ROM with SP Flash Tool or maybe something else, so I would do that first.
For rooting I found this link for Oukitel wp12 with Android 11, I think I would try the same method with K15 Pro

I'm trying to root an Oukitel WP12 with Magisk. I've downloaded the firmware from the vendor's link and flashed it successfully just like for other Oukitel phones (WP6, WP10). I could also create a magisk-patched boot image. I followed regular...

Is there any news yet?

My phone came from AliExpress after 3.5 months, jeez. Got a refund, too, which I might return, never mind.
I dumped/backed up ROM partitions, except userdata because it's big and backup unnecessary, unless you want to keep your personal data in raw binary state for later, and rooted the phone.
You need MTK VCom drivers installed, e.g. from here:
Download MediaTek USB VCOM Drivers for Windows (32 & 64 bit)
Download MTK USB VCOM Drivers for Windows 10 to connect MediaTek phones even in a bricked state. Also, check the Installation guide.
www.ytechb.com
Use mtkclient:
mtkclient/README.md at main · bkerler/mtkclient
MTK reverse engineering and flash tool. Contribute to bkerler/mtkclient development by creating an account on GitHub.
github.com
I unlocked bootloader first. Remember UNLOCKING BOOTLOADER WIPES ALL DATA, returns to factory settings, back up all personal data to PC or SD card first!
To unlock bootloader, if you don't know, go to Settings, About Phone, tap 7 times on Build Number, You are Developer flashes on, go to System, Developer Options, OEM unlocking on, USB debugging on.
MTKCLIENT has a command to unlock the bootloader, it would surely work, I used Fastboot before I learned of mtkclient.
If using Fastboot, turn off phone. Hold Volume up and Power. Choose Fastboot. Connect phone.
You need Minimal Fastboot and ADB installed:
Download Minimal ADB and Fastboot Tool (all versions)
Download the latest version of Minimal ADB and Fastboot Tool which allow you to install and setup the ADB and Fastboot files on the computer.
androidmtk.com
Open CMD, type:
fastboot devices
if phone is listed, then type:
fastboot flashing unlock
fastboot reboot
Never re-lock the bootloader if your phone is rooted or GSI Lineage or other ROM other than original is installed. More than likely would brick the phone.
Everything is explained in mtkclient readme, line by line.
I used Windows 10, works on 11 too, there is a guide for Linux, and even a Ubuntu live image to use. Back up partitions first. Oukitel still haven't posted ROM, but can extract it from the phone, no problem.
Root is explained, need to get modified Magisk for MTK, and flash patched boot and empty vbmeta. It worked like a charm. There are guides on XDA on how to flash System GSI images to Android Super partition. Might try it later. One is here:
How to flash GSIs on devices with dynamic super partition

GSI Lineage images are here:

You couldn't add GAPPS, though, no TWRP, unless there is another way, doubt it. Could install replacement MicroG. Plenty other GSI images here:

I unlocked bootloader first. Remember UNLOCKING BOOTLOADER WIPES ALL DATA, returns to factory settings, back up all personal data to PC or SD card first!
To unlock bootloader, if you don't know, go to Settings, About Phone, tap 7 times on Build Number, You are Developer flashes on, go to System, Developer Options, OEM unlocking on, USB debugging on.
MTKCLIENT has a command to unlock the bootloader, it would surely work, I used Fastboot before I learned of mtkclient.
If using Fastboot, turn off phone. Hold Volume up and Power. Choose Fastboot. Connect phone.
You need Minimal Fastboot and ADB installed:
Download Minimal ADB and Fastboot Tool (all versions)
Download the latest version of Minimal ADB and Fastboot Tool which allow you to install and setup the ADB and Fastboot files on the computer.
androidmtk.com
Open CMD, type:
fastboot devices
if phone is listed, then type:
fastboot flashing unlock
fastboot reboot
Never re-lock the bootloader if your phone is rooted or GSI Lineage or other ROM other than original is installed. More than likely would brick the phone.
Everything is explained in mtkclient readme, line by line.
I used Windows 10, works on 11 too, there is a guide for Linux, and even a Ubuntu live image to use. Back up partitions first. Oukitel still haven't posted ROM, but can extract it from the phone, no problem.
Root is explained, need to get modified Magisk for MTK, and flash patched boot and empty vbmeta. It worked like a charm. There are guides on XDA on how to flash System GSI images to Android Super partition. Might try it later. One is here:

You couldn't add GAPPS, though, no TWRP, unless there is another way, doubt it. Could install replacement MicroG. Plenty other GSI images here:

Thanks for the reply. I had a few problems with micro g on MI A2. After flashing micro g in magisk is there a certain gapps I need to flash? Or can I just download Google services after flashing micro g

I was wrong about LineageOS not having GAPPS preinstalled. The link I gave you:
Andy Yan's personal builds // GSI - Browse /lineage-19.x at SourceForge.net
sourceforge.net
has this system image of LineageOS with GAPPS included, vndklite are read/write system images that I saw someone said were working on Oukitel phones with Android 11, and are generally probably best to use, so if you use that one, you don't need microG, which would have to be installed from F-Droid store or something like that:
https://sourceforge.net/projects/andyyan-gsi/files/lineage-19.x/lineage-19.1-20220410-UNOFFICIAL-arm64_bgS-vndklite.img.xz/download
G or g in the name of the system indicates that GAPPS are included.
I will try to flash that one myself sooner or later. It's based on Android 12, and if it doesn't work for some reason then we would have to drop to Lineage 18.1, but those aren't with GAPPS, so microG required:

There are other ROM with plenty of customizations that might be ok.

OK, it is possible to install Android 11 GSI system images on this phone. Android 12 images do not work, something to do with incompatible boot partition.
It's possible to try out GSI system images without flashing by installing this app:

Root is useful, but not necessary. Seems not to work, maybe needs flashed empty vbmeta_system and vbmeta_vendor like indicated below and I restored all to stock ROM except for boot.img with Magisk 24.3 and empty vbmeta.img
If you managed to make full backup of ROM with mtkclient, enable USB debugging, unlock bootloader, then to flash GSI images or Lineage 18.1 based on Android 11 (it works, but no image with gapps unless found somewhere else) you have to have installed Google Android USB driver from here
Get the Google USB Driver | Android Studio | Android Developers
The Google USB Driver is required to perform adb debugging on Windows with Google devices.
developer.android.com
Unpack files, connect phone in recovery, power + volume up then power+ volume up fast click, choose fastboot, that gives you FastbootD (colorful menu), which is now used to flash system partitions. Connect phone, install driver with .inf file.
You also need Google platform tools
SDK Platform Tools release notes | Android Studio | Android Developers
Android SDK Platform-Tools is a component for the Android SDK.
developer.android.com
Unpack anywhere if on Windows.
Run cmd, then "fastboot devices" to see if phone gets detected, should be there.
From here get product_gsi.img:

In mtk client is an empty vbmeta file - vbmeta.img.empty or similar, needs to be flashed to vbmeta, vbmeta_system, and vbmeta_vendor to disable verification of boot for magisk, and system and vendor for GSI system images. Can be done with mtkclient or normal fastboot ( power + volume down, choose fastboot, connect phone, run cmd, then "fastboot flash vbmeta vbmeta.img.empty (could be renamed to anything simple, name doesn't matter))
Then
fastboot flash vbmeta_system vbmeta_img.empty
Then
fastboot flash vbmeta_vendor vbmeta.img.empty
Same file to all three partitions, disables verification, worked for me. Can be done with GUI in mtkclient, same thing. Or commands in mtkclient
"python w vbmeta vbmeta.img.empty"
Etc.
Back to FastbootD -
"fastboot reboot fastboot" or power + volume up for recovery then click them again, choose fastboot.
Or probably "adb reboot fastboot" if phone is running system.
Run cmd, "fastboot devices" to be sure phone is detected, then
"fastboot flash product product_gsi.img"
This resizes dynamic system partition when flashing system images. This only modifies internal logical partitions within SUPER partition that contains Product, System, and Vendor. SUPER can be restored with mtkclient or just fastboot, I guess, I restored with mtkclient, works.
Then you can flash any system based on Android 11, stock phhusson GSI works. the system needs to be arm64, ab (for A/B partitions, indicated by letter B in name), vndklite, G or Gapps (if you want them), V is vanilla - no gapps, S is superuser but seems to have conflicts with magisk if you want that as root later. N is no superuser/root.
Eg.
"fastboot flash system Lineage-18.1-2021214-UNOFFICIAL-treble_arm64_bvS-vndklite.img" Rename this to 1.img or whatever, simpler to type
"fastboot flash system.1.img" or something like that.
"Invalid Sparse System Image At Magic Header" appears, but doesn't matter, starts flashing in 30 seconds or so, 10 or 11 chunks, maybe 2-3 minutes per system image.
Then
"fastboot reboot" go to recovery, power +volume up, click them again, choose wipe user data, wipe cache to get rid of old settings and apps from previous system.
"fastboot reboot recovery" should work too.
Seems that on custom ROMs Magisk 24.3 app gives option to directly patch boot image without need for flashing patched boot.img. Not sure about that. Just flashing patched boot.img in fastboot gives root, anyway.
If you just want newest Magisk then flash empty vbmeta and then patched boot Magisk generates. Those can be done in normal fastboot. Works fine.
Everything seems to work.

Magisk zip install on TWRP, now Lineage OS wont boot

When booting now just stuck on "Boot loader is unlocked" warning screen. When booting into TWRP using volume and power buttons, all my restore options are random alphanumeric characters (I think this means encryption...).
I checked both slots, one is for the bootwarning screen, other is for TWRP... What do....

restore the backup of vendor or use from download. reason: magisk from recovery requires parameter to preserve encryption, otherwise the fstab is modified in a way encryption is no longer functional.

How can I restore anything in TWRP if everything is alphanumeric babel (encrypted)?
What are my options realistically in this situation?

download vendor and flash from fastboot or adb
