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
For A30: https://forum.xda-developers.com/galaxy-a30/how-to/root-galaxy-a30-magisk-canary-relaese-t3936481
2. Install TWRP and remove data encryption.
For A20: https://forum.xda-developers.com/ga...p-samsung-galaxy-a20-custom-recovery-t3955271
For A30: https://forum.xda-developers.com/galaxy-a30/development/recovery-twrp-galaxy-a30-t3968085
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)
Back boot data and system
3. Wipe both caches, data & system
4. Install GSI
5. Flash Magisk and physwizz GSI kernel from here https://forum.xda-developers.com/t/kernel-physwizz-kernel-for-the-galaxy-a20.4180107/
6. Reboot.
2. Installing GApps
Some GSIs come with GApps. If you're doesn't and you want to have GApps, then use this method.
a.-Resize system partition so you can install OpenGAPPS, go to wipe, advanced wipe, select system, select repair or change file system and select resize file system. If you get error 1 unmount and mount the system partition and try again
b. Install GApps
3. Fixing Navbar
As soon as you boot up. Run Magisk and install this module.
View attachment navbar-enabler.zip
4. Android 10 Backup
Backup Data only (EvolutionX and Havoc 3.0 will do boot/data/system backup and restore),
5. Android 10 Restore
1. Reinstall GSI (a - h above)
2. Restore Data
3. Install GApps (if needed)

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.

GSI AOSP Android 10
I've tried to open the GSI list you provided.
And I got confused which one do I have to download/pick and which file.
Do you have any recommendations for Android 10 stock AOSP?
Thanks in advance.
Cheers. :fingers-crossed:

arm64 a/b or arm64 bvn/bgn v=vanilla g=gapps

I’ve downloaded the arm64 a/b gapps and go. I’ll try it later. Then I will tell you if I find any bugs and then upload the logs. Where should I upload it?

I am using :
system-roar-arm64-ab-gapps.img from here
TWRP 3.5.0_9-1 SIDDK
ColorOS GSI
adb version Version 30.0.5-6877874
I can't make it run. It loops in opening screen RealmeME (white logo) not Yellow font..
I still can boot to fast-boot mode and call twrp recovery.
Somebody can help me?
many thanks in advance

everything fine with keystore make sure u using latest recovery & using A10 keystore

Ahh...booting into recovery even if i press system

@arksolitude is that because you are trying to install android 10 for realme c2? if yes...
1. download stockrecovery.img (or get the recovery.img from the zip file you've downloaded)
2. reboot to bootloader/fastboot
3. type in your computer "fastboot flash recovery (name of the file).img"
4. reboot (this will take you to stock recovery)
5. wipe data and reboot
this is from my experience but this should work

You need to be on MIUI based on Android 11.
Flash this fastboot ROM which is 4.9 GB:
Xiaomi Firmware Updater
The ultimate script that provides firmware packages for Xiaomi devices.
xiaomifirmwareupdater.com
Use Mi flash tool to flash it.
Unlock your bootloader.
Flash the recovery from here:
myromupdates - Browse /surya/TWRP_brigudav at SourceForge.net
sourceforge.net
Install ArrowOS (I suggest the version with GApps included)
Format DATA (format, not wipe). It's where you have to type 'yes'.
Don't do any other formats or wipe. Only format DATA after flashing ArrowOS.
Restart and enjoy. This instruction works 100%

Question Anyone figured out how to flash a GSI on this phone?

I bought this phone because I needed a new phone desperately. I am used to using lineageOS on all my phones before so having it would be amazing, especially since I hate having Google spying on my phone
