GSI for the Galaxy A20 (Android 10)

What is GSI?
GSI stands for Generic System Image and will allow you to install an alternative ROM on your Galaxy A20?
No longer will we be restricted to the Samsung ROM.
These ones worked for me. If they don't work for you, go to the list of all GSIs. There are plenty to choose from. Select arm64 ab files.

Before you Start
1. Make sure your phone is rooted
For A20: https://forum.xda-developers.com/galaxy-a20/how-to/root-samsung-galaxy-a20-rooting-guide-t3954872

Quick root and TWRP together for the A20: https://forum.xda-developers.com/galaxy-a20/how-to/guide-quick-root-twrp-galaxy-a20-t4069423
3. Backup only 3 parts: boot, data & system (not system image) onto external SD or usb-otg. If something goes wrong you should be able to restore the phone using TWRP.
4. Also use SMS Backup and Restore so you don't lose your messages or calls.
5. Make sure your Ext SD card is Fat32. I've noticed that GSIs don't recognise ExFat.
Android 10 (Q)
1. Installation
1. Begin with stock ROM
2. Reboot into TWRP ( then mount product - system - vendor)

So method 1 have you the same result as method 2
Can you backup with either method?
Method 1
For the SM-A205YN
Download the A205YN custom recovery from here
https://forum.xda-developers.com/sho...&postcount=169
No need to patch it. Just flash it with Flashify.
If this first method works for a different version, please let me know.
Method 2
For the SM-A205G,
Download the composite recovery from here.
https://forum.xda-developers.com/sho...&postcount=198
Install to ap slot using Odin.

Magisk/Twrp for GSI (Won't work on stock)

I have a Twrp backup with the boot img patched with Magisk/Twrp boot to recovery boots GSI with magisk boot to recovery hold volume up while rebooting to recovery will boot twrp for this boot img to work u have to be on the vendor of the boot img which is also in the backup so the phone won't bootloop this vendor is modified to work with GSIs pass the magisk environmental setup and notch fix so swiping down is like swiping down on stock.... to implement notch fix go to developer settings hide display cut and choose the first hide option and your notch will be fixed...
Thanks @Spaceminer for the twrp for without this none would of been possible
please note twrp will only boot with a android 9 vendor and your GSI will only boot with magisk and twrrp with the vendor in the backup cause it matches the boot img, GSIs only boot when the vendor and boot img match
the boot img & vendor img in the backup is from Channel/Retail (PPY29. 105-160-4)
Instructions
If on android 9 stock
1. Boot to bootloader
2. fastboot - w
3. fastboot GSI of your choice
4. fastboot boot twrp.img
5. format data
6. Place the twrp folder you downloaded from the zip into your devices internal storage which will be available after u format data
7.Resize system
8.Flash gapps zip if gapps is needed
9.wipe dalvick
10. go to twrp restore boot and vendor
11. reboot to recovery and phone will boot after boot is complete install magisk manager it will do the environmental setup phone will reboot and u will have magisk.... ( if u want the best experience with magisk on this device I recommend that you use havoc cause with the lineage GSI magisk doesn't play nice but with havoc its stable also when making a backup it's boot, system image, vendor image, data if u chose system instead your backup will bootloop your device upon restoration)
Download (twrp img is in twrp folder remove it and place it in ADB folder)
https://mega.nz/file/7t03DLhL#jjS9vgrJMlDS-_-hsApyx4uJ6L8wXCN8HtjSqJrg2ds
if u wanted to do this manually to install the latest canary or stable version magisk need to patch twrp to the recovery flash phh root boot up install magisk manager give it root permissions with phh superuser from apk mirror now with elevated permissions the option patch directly will be avaliable cause u got root (it's the recommended option ?) chose recovery and leave the other 2 unchecked patch the img and reboot to recovery the phone will reboot os with magisk and u hold up while booting recovery will boot twrp after that backup that boot img in twrrp for future installation of the GSI of your choosing....

Hello,
Already figured it out.

Everytime u flash a GSI just use the vendor and boot from the twrp folder and your android 10 GSI Will have magisk and twrp no need for data disabler zip cause my backup already has the vendor and boot patches enabled for decryption so twrp will be accessible via boot to recovery
([emoji88]Havoc GSI[emoji88])

Also have edxposed for Android 10 since the one in the repo won't work cause it needs a custom magisk with merged patches for xposed to work on android 10 this version has the patches in the edxposed so having to use a custom magisk won't be an issue cause as ya know obtaining magisk and twrrp in this device was unknown into this OP was made

Thanks so much for the instructions, only way i could install on G7 play.
The only thing is I always have to boot in recovery mode to start the system.
If I boot normal it starts again. Any way to solve this ?
I think somehow I flashed my ROM to the recovery partition ?
thank you!!

Your on a GSI go in your system settings and activate advance boot and when u have to reboot just put reboot to recovery and you don't have to worry about manually rebooting to recovery everytime u have to reboot also no way u installed the rom to the recovery partion our device doesn't have a recovery partion the recovery lives within the boot img
([emoji88]Havoc GSI[emoji88])]

thanks, not sure if I can do this with my Treble gsi (phhusson).
The other thing is that some things got messed up after instalation for example I cannot put in a passcode for the phone.
Is there no other way to install magisk on the G7 play ?
Maybe this has to do with the vendor and boot beeing different model than mine wich is XT 1952-2 (latin american model)
thanks

The reason the lockscreen doesn't work is cause the device is decrypted which is essential for the device to be able to reboot to twrp my vendor has the decryption patches for the full functionality of twrp however if u don't care about twrp and just want magisk just patch a fresh version of your boot img in magisk manager with the patch a file option and fastboot that boot img to your device install fresh GSI with your vendor so it will boot encrypted since your vendor doesn't have the decryption zip patches in the vendor... However with this method to have full functionality with magisk u will have to remove from vendor/bin/init mimi hab if this file isn't removed your magisk won't pass the environmental setup... U be given root privileges with magisk before u have to do the environmental setup so u can remove that file...

Yes I understand, sounds logic. I tried to follow your guide but it didn't work.
I did the following:
1. Followed your first instructions with restore vendor and boot in the end to have magisk twrp (Now on Android 10).
2. patched the boot.img (stock one Android 9) with magisk and pulled via adb on computer
3. fastboot flash boot boot.img (patched)
4. Fastboot flash system gsi.img (android 10)
After that I get a bootloop if I go via normal boot and recovery doesn?t boot either.
In the end I tried to flash the stock vendor.img but everything stayed the same.
Not sure how to remove the file in the /vendor/bin, with twrp ?

The easiest way I know of is from the stock OS using termux and root.
Code:
su
setenforce 0
mkdir /mnt/x && chmod 0755 /mnt/x
mount -o loop /dev/block/by-name/vendor_a /mnt/x
Now navigate to /mnt/x and everything from vendor will be in there. Find the file and delete it with a root explorer. Then unmount the partition and the changes will be permanent. Doing it this way gets around FEC, which is what prevents you from changing anything in vendor.
Code:
umount /mnt/x
If you need to work on the other vendor partition just change out vendor_a with vendor_b

Chaos GSI Bluetooth works without disabling audio effects (so u can use viper with bluetooth headset) it's clean stock with minimum stuff added to it and works with gravitybox then you got havoc that has the majority of stuff gravity has off the rip so it's not as minimum so more memory usage is needed and Bluetooth only works with the phh disable audio effects work around also magisk works good on both of these lineage is good also if you don't care about magisk working cause with our device magisk has issues on lineage don't know if it was fixed on a recent bulid however if lineage is your preference there is a phh root for it so u can be functional

My device is xt1952-4. I downloaded the latest firmware (PPYS29-105-160-4-8), and installed it to both slots. I am currently using Resurection Remix Pie. Is your patched boot.img and vendor compatible with the newer firmware or will I get a downgrade error?

Project Treble Device goes into bootloop after any custom rom. Doogee N20

My doogee n20 goes into a bootloop after any android custom rom, like i tried phh treble, pixel experience and my device softbricked every time, Android 10,11 doesnt matter still bootloops, i am trying to update my android version but the phone has a-only partitions which restricts me from android 12 right now, i can root and/or twrp but custom treble roms are a no-no. Any help please? NOTE: no i dont want to get softbrick fixed, i have a sp flash tool backup and it works, i need a way how to install hopefully android 11 or 12, android 10 is ok too.

Project Treble has nothing to do with Android's partion-layout, what may be a A-only one or A/B one - with the latter there are two virtual hard drives that each contain a copy of Android.
Project Treble means Android is parted: part #1 what contains the lower-level code created by silicon vendors, and part #2 what contains main Android operating system framework. So device manufacturers can update the OS code without having to rely on silicon vendors to refresh the lower-level code for every release.

Phh treble work perfectly on my Doogee N20 and by the way it is A/B not A only. And, but one thing I needed to install vendor.img the first time I installed a Gsi.

Try this
1. Download GSI for Arm64 A / B and extract then.
2. Download firmware stock here
Firmware doogee n20 by 4pda
3. After downloading the Stock firmware extract the vendor.img
4. restarted in TWRP, go to clear,select Dalvik / ART cache, system, data and cache, drag flash bar
5. Go back, go to install, find the folder where the GSI is, select install with system image, go back and find the folder where vendor.img is and select install with vendor image
6. Reboot system

With this recovery, it's hard to call it a bug, since I stupidly disabled the screen timeout in the settings and everything is ok

Hi, there's such a problem here, the touchscreen does not work on gsi firmware after the screen is locked, if the phone locks, or the screen just goes out, then the touchscreen stupidly no longer responds to clicks, and you have to restart, just like in twrp

Are there any similar cores with a12 for m12 that can run gsi firmware?

Hi, I have such a question, I want to completely cut out all the system garbage from the firmware so that it can be installed via odin and there was no junk, since I just couldn't remove them from the off firmware, I think to do so, cut out all the garbage through the phone, delete all the extra folders, make a backup system and convert to img, and then flash through odin, will such an idea work?

Hi,
I tried the recovery in my m127g (u2). Though the recovery is actually for u3. As I haven’t yet found any working version for mine.
After I wipe, format data, it says, "Failed to mount '/data'." (attached photo 1)
After typing multidisabler in terminal, it says successful. (attached photo 2)
Any advice will be appreciated.

No it won't work for u2.

There was a problem I faced lately.
I had to flash my phone yesterday, tried to install the TWRP. The problem was internal storage not showing. Formatting and multidisabler doesn't help. Results in bootloop.
What works for me is installing OrangeFox (provided by you), formatting and typing multidisabler. Then use the method 1 here. Just for your information.
After installation it works fine.
