(Note, I did not make this rom. This is a Generic System Image (GSI) made by Caos' devs. so it is not specifically built for the A51, but it's really stable and I am using it now. ALL CREDIT GOES TO CAOS' DEVS!)

Your warranty is now void!​

We're not responsible for bricked devices, dead SD cards,​

thermonuclear war, or you getting fired because the alarm app failed. Please​

do some research if you have any concerns about features included in this ROM​

before flashing it! YOU are choosing to make these modifications, and if​

you point the finger at us for messing up your device, we will laugh at you​

​

CAOS (Custom AOSP OS) is a project which is based on @phhusson's Treble GSI AOSP 10. CAOS' devs began it because ASOP has stability, speed and support but also some issues and limitations - pure AOSP's code has some bugs and it doesn't have much useful things and it's hard to pull it. So CAOS' devs did this fork. System can run with SELinux enforced state, as an original Phh AOSP GSI. Fully compatible with PHH-Treble patches exclude few low level changes: no root app, no "su" binary in system; by default exist file /system/phh/secure (for Google Certification PASS), so if you can boot AOSP GSI, but can't boot CAOS - try to removing that file

UPDATE VERSION

latest build: 2020.10.29

treble patches: v222+

SPL: 5 Oct 2020

File Downloads/Installation​

THINGS THAT YOU NEED ON YOUR WINDOWS COMPUTER.​

Odin

Unzip the file. There is a EXE file in it. Double click it to launch. There will be a pop up, just press ok.

FILES THAT YOU NEED TO FLASH THE ROM.​

The rom itself

Make sure you have 7-zip installed. Right click it and click extract files. Go into the unzipped folder and rename the file inside to "system.img"

TWRP Decrypter

Just leave this file as a zip. Don't unzip it.

ChonDoe Flasher

Just leave this file as a zip, Don't unzip it.

INSTALL RECOVERY AND UNLOCK BOOTLOADER (SKIP THIS PART IF YOU ALREADY HAVE TWRP.)​

I have made a reddit post on twrp. DO NOT DO THE MAGISK PART.

FLASHING THE FILES​

Go into TWRP. Press wipe and go into format data. Type in yes and wipe your data. Press the home button in your nav bar and go back into Wipe. Press advanced wipe, tick "data", "Dalvik / ART cache" and "Cache". Format it.

Press the home button in the nav bar again. Now, go into reboot and click recovery. Don't do anything. Once it's back into TWRP, plug your phone into the pc if you haven't already.

On your Windows PC, go into File Explorer, This PC, A515F and then internal storage. Take the "system.img" file and drag it into there. Do the same with "Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip" and "ChonDoe_Flasher.zip"

Once all of them are copied, go onto your phone. Click install and you should see your files. If you don't, go into /sdcard. Flash "ChonDoe_Flasher.zip". Once it's done, flash "Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip". Press "Reboot System" once "Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip" is installed.

If this looks really confusing to you, there is a tutorial for this. However, it's for HavocOS. But everything is the same except the rom. But the steps are the same. Watch it here.​

Congrats! You have installed Caos!​

• excluding fixes, the same as on AOSP Quack (in some cases doesn't work: broadcasting on TV, calls via BT; offline charging does not work normally fingerprint doesnt work; problems with GPS etc etc)
