Hello forum guys, I've registered now to see if any enlightened souls could help me.
So straight to the problem...As stated in the title I have a Galaxy A02s and I am having problems with its Android.
I did a lot of research but I'm just getting more doubts, I read things like custom mod, kernel 64, treble info, and so on.
I will specify my device with the Aida64 information for better understanding:
Chipset: Qualcomm Snapdragon 450
Core Architecture: 8x ARM CORTEX-A53 @ 1804MHz
Manufacturing Process: 14nm
Instruction Set: 64-bit ARMv8-A (32-bit Mode)
And Treble Info says:
In the Architecture part: "Your device is ARM32 but uses a 64-bit binder. This usually indicates that the hardware supports 64-bits but the software does not. In this case, a 'binder64' or 'a64' image should be used. "
And in the Image Requested part: "Your device needs an image file called 'system-arm32_binder64-ab.img.xz.'"
I don't know if this Treble has anything to do with leaving Android in 64-bit, but I was researching and researching and that's what I got, however, I have little knowledge about these things and I didn't find any tutorial teaching how to install/update to 64-bit
That's it, I hope you can help me, thank you in advance
What's your real problem?
Any 64-bit SoC flawlessly runs 32-bit Android OS and 32-bit apps

sorry, stopping to read again what i wrote i realized i didn't specify what i needed help lol
So I just don't want this 32-bit mode, I googled to see if my processor had architecture to run in 64-bit, and apparently yes, so I wanted to put android in 64-bit, but I have no idea of how to do this
thanks again
Replace this thread's title by your real problem: How to reflash Galaxy A20s with 64bit Android
Certainly, you flashed a 32bits system.
Just flash a 64bits system.

I bought the phone and it came like this, but how do I do it ? To a 64bits system
I'm also with the same problem, I would need some ROM for the 64-bit system, but I realized that there is none so far, is there any other way to change it to 64-bit without changing the ROM?
Short answer: NO
Short answer: NEVER
I'd like to ask how is the 32bit system with the 64bit system?

I have been trying for some time now to enable KVM on the Pixel XL, by compiling the stock Google kernel and adding the KVM switches to "marlin_defconfig".
Unfortunately, while the kernel with KVM compiles properly and could be flashed, /dev/kvm doesn't show up.
Analyzing the output of "dmesg" would show this offending line:
Code:
[ 1.039716] c3 1 kvm [1]: HYP mode not available
I know, however, that the SoC definitely supports KVM (it's based on the ARMv8-A architecture, which means that it has virtualization support, according to this page: https://www.linux-kvm.org/page/Processor_support).
I'm stumped. Can anybody tell me what to do? It would be greatly appreciated!
My marlin_defconfig is attached below.

Was going to post it under Q&A, but changed my mind, since (a) it's a dev-related question warranting dev attention, and (b) I expect that this thread is going to become the "official" thread of the kernel once it's done.
Thanks for your concern though!
how does kvm affect the kernel? are you trying to add it just for the hell of it? or wanting to work on something bigger?

It's already built-in the kernel sources, but I'm trying to enable it. I am actually attempting to run QEMU in KVM mode as to emulate both Linux and (most importantly) Windows 10 ARM. at native speeds.
I have QEMU built (Limbo's is too old, so I built it myself from source), I just need KVM.

You can't use kvm even If you enable it in kernel.KVM on ARM is based on the ARM virtualization support, i.e. you'll need ARM EL2 permission (on ARMv8) or HYP (on ARMv7).Just like on x86 , you'll have to enable VT-X or AMD-V in BIOS or so.
However sadly, on Qualcomm devices, EL2 isn't designed to be in our reach, even If you unlock bootloader ,all you'll get is full control of EL1.EL2 is instead running QHEE,which is basically for security.So if you still want to run kvm on a Qualcomm device you'll at least either need a prototype device(unfused) to custom qualcomm bootloaders and underlying stuffs, and let your kernel running in EL2, or need a really really powerful exploit like trustzone exploit, to take the control of EL2, EL3, breaking chain-of-trust etc.
Android phones are mostly designed for security concerns and mostly shipped without hypervisor permission.However there are some exceptions like Samsung Exynos that allows you to switch to EL2 with some specific ways.

I dunno if this works.(Samsung S8 example)Afaik on Exynos you need a special SMC call to the secure monitor (ARM EL3)

I've seen that link. It's basically a kernel compilation guide.
It also makes a serious mistake: that an x86 VM would be able to make use of arm64 KVM. This is impossible.
But what I haven't seen anywhere is this:

Arm el2 patch
I was searching about KVM and I found that to linux/Android must be boot in EL2 mode for KVM to be work
And I found arm64 el2 patch :
https://patchwork.kernel.org/patch/6749811/
So I would say that try this patch,compile kernel again and install it and paste result here.
If it doesn't work,then try xen virtualiztion but first try this patch
Thank you, waiting for result
Ever get this to work?

I was wondering if you ever got this to work, since I have an exynos device and am trying to get kvm to work too. Also you ever try this: https://patchwork.kernel.org/[email protected]/ patch? Cause if not I might give it a ago.
Same here, enabled the necessary kernel flags, flashed, but still dmesg informs me my cores are at EL1.
Seems @fxsheep has a clear point, but, who knows.

This just uses Exynos-specific exploit, and as such useless for Snapdragon devices.
Hey guys,
Been working on a personal project, and came to this question, which also happens to be the first Im having to post about online..
Is it even possible to boot the kernel in EL2 mode with the sdm845 SoC ?
My end goal here being running qemu - which I'm already are - under KVM ( The tough part )
I Already tried enabling the necessary options in the kernel build, flashing them, with no success.
What I've been reading around is that since the system uses the TrustZone environment, this may not be possible.

On the other hand, under the chipset specifications I've been seen that only EL3 is really protected by the security implementations.

I know some exynos chipsets support booting in EL2 out of the box, but I see not much development for Qualcomm based ones.
ARM KVM (Kernel Virtual Machine) enabled Kernel for Samsung Galaxy S8
Hi. Can someone that compiles kernels for this phone compile one with KVM enabled and make it available to download? It should not be too hard. This would really make these machines appealing if you could spin up VMs on them especially...

Limbo is a QEMU-based emulator for Android. It currently supports x86, ARM, PowerPC, and Sparc emulation for Intel x86 and ARM android devices. See wiki https://virtualmachinery.weebly.com for APK...

So, summing up, is it possible, and if so through what actions, to boot a kernel under LE2 mode on a snapdragon processor?
Also, side note, I'm willing to brick my device, if its worth the try, and adds to any progress of future development.
Edit1: Added links- sources
Cheers!
Sadly, with SDM845 it is impossible to enable KVM in android Linux kernels. As the kernel is booted under EL1 by the firmware. But with this firmware https://github.com/msm8916-mainline/qhypstub, msm8916/msm8935 can.
Is there a way to enable KVM for SM8450 (Snapdragon 8 gen 1) ? I would like to use Qemu on Galaxy Tab S8

How i check my device booting with EL1 or EL2 ?
Via `dmesg` ?
i picked up on a s5 neo because of the 64bit cpu over the snapdragon 801, cost only 60$ and is supported by lineage-os to my surprise the latest official version of it runs on 32bit even though the cpu can run 64bit, i did look at phone info [samsung] on the stock rom and it ran in 32 bit as well, the most i know about it is that it was android 6.0.1, so my questions is will lineage-os put this phone on 64bit since it can run it and did it ever have 64bit support at all from android, because i didn't try android 7 at all, i did try the Cosmic-Kernel that appears to run in 64bit but truth be told i haven't got a clue what im doing as to install it so i didn't try to hard to install it, heres a link to the github for it

You have to distinguish between a device's Linux kernel and device's Android OS. Both are different to each device.
A kernel for Android OS basically is a mainstream Linux kernel, with additional drivers for the specific device, and other additional functionality, such as enhanced power management or faster graphics support.
If I'm not mistaken the kernel determines if the OS is 32bit, not necessarily the OS am I right or can the OS and kernel be 32bit
Actually any 64-bit ARM SoC can run 32-bit software ( Linux kernel -> modules, Android OS -> libraries & executables ) due to its 32-bit compatibilty mode.
This will change: ARM has announced that from 2023, all of its new smartphone CPU cores will be 64-bit only, with no 32-bit compatibility mode.
BTW:
Have never heard that Linux kernel determines whether Android OS has to run in 32-bit mode or 64-bit mode.

I know of running 32bit software on a 64 bit processor works on the same way with typical desktops and laptops, I'm trying to figure out how to make it run in 64bit mode, and determine the easiest way to do it
Hi,
I was just wondering if there is any forum specific for xFSTK?
Lots of Android devices have an Intel processor and considering the hugh number of different types of Intel processors it might be worth to have a forum specific for xFSTK, whatever the target processor in the device and whatever the platform xFSTK is running on (Win PC, Linux, Mac).
I'm also asking this because I have a post about xFSTK (see link) but, considering the post is related to an old device, it will probably not get any response while the error(s) in the xFSTK log may also appear with other devices and Intel processors.
Thanks in advance

Hello everyone
Briefly , I try to understand HOW to mod our Sony BRAVIA 4K VH21 UC TV to go from 32 to 64 bit in order to install the Dolphin emulator.
on Dolphin website the requirements are :
System Requirements
The following are requirements your Android device needs to meet in order to install the application:
Android 5.0 or higher
A 64-bit processor (AArch64/ARMv8 or x86_64)
A version of Android that supports 64-bit applications
A graphics processor that supports OpenGL ES 3.0 or higher.
If your device fails to meet any of these requirements, attempting to install Dolphin will return an error message reading "Application not installed."
Note that some devices are equipped with 64-bit processors but ships with 32-bit builds of Android. Installation will fail on these devices as well. There's no way to fix this, and no manufacturer has updated a 32-bit only device to support 64-bit apps.
our Sony Bravia have theses specs :
-- Android 10
-- 4x ARM Cortex-A73 @ 1800 MHz / 64-bits ARMv8-A (Mode 32-bit)
-- OpenGL ES 3.2 v1
Downloaded DOLPHIN 5.0-17995 and APK installer
the app refuse to install saying the app is incompatible....
I feel im touching the dream at the tips of my fingers
Please tell me its fesable with my specs and how to proceed step by step
I HOPE someone will be able to help me (but you are all invited for sure
HAPPY NEW YEAR 2023 guys !

Hi
thanks for your answer.
QUESTION 1 : BEFORE i proceed , did the process is reversible ?
It will not be hard/impossible to re-install app like youtube/netflix ?
QUESTION 2 : where i can find such custom rom ? I have to make it myself ?
QUESTION 3 : Did you have a step-by-step tutorial to do so ?
As you can see here obviously a Custom Recovery - what is prerequiste to install a Custom ROM - isn't available.
But may be you find one doing a related Google search.
