[HELP] Need help upgrading to 64bit - Samsung Galaxy J7 Questions & Answers

Hi Mates! I am kinda late in 64bit rom party. I am trying to read as many as possible post just to understand it. First, if i upgrade to 64bit rom, can i play some of the 64bit games that is not compatible with our device. Second, can you explain the process. No need in pointing the link just the files that i need to download and flash. Thank you so much.

Have a look here about the meaning of 32 and 64 bit hardware and software:
What is the difference between a 32-bit and 64-bit system?
An explanation of the difference between 32-bit and 64-bit, and what the terms mean in reference to hardware and software.

Hope that helps to understand the difference and how it works together.

Afaik if you have a G610X device then natively the phone supports A64 which means Arm (32-bit) with 64-bit binder. This means that the OS is 32-bit while the hardware is 64-bit capable. There now exists vendors that cater to both Arm64 and A64, Treblue and TheRealVendor respectively. If you like to go Arm64 (A-only), try Treblue vendor and flash some GSI's like Crdroid, LineageOS, or Havoc, among many others. If successful, then yes you can start up 64-bit (Arm64) apps and games, albeit it may be really laggy as the phone, while 64-bit capable hardware-wise, meets the bare minimum to even run these newer games and apps. But at least you can use them to some extent rather than not on Arm and A64...

Thanks for the answer bro. I already flashed HROM by Astrako. Last thing though, can you recommend any GSI/Pixel like rom? I was wondering if there is any semi stable gsi rom. I'm kinda craving for new ui.

Lots of GSI's to choose from like LineageOS, HavocOS, CrDroid, Corvus, Pixel Experience, FluidOS, AOSP, etc.... Just check out each to see which fits your needs. Just make sure that the version you are getting is compatible with your vendor.

Hasty (Ubuntu 8.04 'Hardy Heron') compatible with ARMv6 - Can it be done on the G1?

I know we have successfully been able to install debian on our phones, has anyone tried to install hasty (basically a build of Ubuntu 8.04 'Hardy Heron')? Although ubuntu is releasing an ARM version for ARMv7 processors in April 2009, our G1's would be left out because it is ARMv6.
However, there's a version of hasty compatible with our ARM 11 Family (ARMv6) (http://www.arm.com/products/CPUs/families/ARM11Family.html) processor, found here:
http://mojo.handhelds.org/hasty-armv6el-vfp
I wouldn't even know where to begin with installing this, so if someone could enlighten us on how to do so, it would be greatly appreciated.
why?
ubuntu is just debian with some user friendly tweaks, but none of those would apply to a cellphone. so it would basically be exactly the same as debian.

We've gone as far as installing debian, why not ubuntu? Personally I would like to see if any of those tweaks would work on my G1. I understand there are similarities, and that ubuntu is based off of debian, but it wouldn't hurt to install it as opposed to debian would it?

Why not just use http://www.ubuntu.com/products/mobile, when it decomes workable? Or wait for vmware mobile edition.

It's not being planned for ARMv6 (which the G1 has), only ARMv7
So has anyone given hasty a try yet? =]

Hi Red. I was taking a look at the ROM repository on GitHub, and saw that the default branch is now named cm-13.1. So, are you now working on an Android 6.0 ROM for the M5c?

I have a slight indecision, now I can not carry on the Custom ROM because I do not have the right PC but when I am able to compile it, I will evaluate which one can work better

I see. I would say that in the long run Lineage 14 would be more worthwhile, since Android 6.0 is becoming outdated, with no support for some apps. But really, I just wanted a ROM to replace Flyme, and its bugs. Also, many of the apps I use don't work, or don't work right on Flyme...
These days I was taking a look at /e/ OS. I've been thinking about venturing into porting this ROM to the M5c. For me it would be a challenge, since I've never done this before. But unfortunately at the moment I also don't have a PC that meets the requirements to compile the ROM

You are right. However, /e/ has some nice features like e account synchronization, an app store, microG, and some of their apps... Of course we could get that with LineageOS, but it is interesting how /e/ already brings that well integrated and ready.
By the way, I am also looking at other non-Android systems, like Ubuntu Touch...

Well, from what I've been reading the process is similar to porting LineageOS. You just need the kernel sources and the device specific binary blobs. I'm guessing you know how to get them, don't you?
And the interesting thing is that there is a layer, called Halium, that interacts directly with the hardware. And that is actually what you should port to the desired device. Then you can install any Linux system on top of this layer, like Ubuntu Touch, Plasma Mobile, etc, and these are distributed pre-compiled.

Mhh ... good, you are informed, however the vendor blobs are bull**** to take, the problem is the kernel sources but Meizu has not released them. However, some time ago I booted a Custom kernel based on ALPS (A custom AOSP from Mediatek to be clear) but the touchscreen doesn't work and I'm looking for a solution around but that I can't find
P.S: Fixing that kernel has great potential, forget android 7, you could also boot android 9 with sources, but as long as they are still working

I confess I didn't quite understand one thing: so how did you port LineageOS to this device? You didn't need the kernel sources?

At the time I was doing this lineage, I was with the prebuilt kernel, week ago I had done this kernel port to a twrp and the touch was not working so I left the device alone

Thanks for the clarification! It is a shame that Meizu does this (I wonder if they are not violating the terms of the Linux GPL license by distributing the kernel without publishing the modifications made to the source code).
Anyway, if a solution to this kernel problem related to the touch screen comes up, please let me know. In the meantime I'll keep reading Halium's documentation until a solution comes along, or until I get a compatible phone.
Great work!
Hello. I've been testing this ROM on my M5c and love it. The ROM is very good, fluid, lightweight... the only problem is that the camera doesn't work, as well as the cellular network data. Congratulations for the excellent work.
The ROM will no longer receive bugfixes?
pls compile

[Research] Supported MTK Custom Roms?

Hi All,
I'm looking for active MTK Custom roms.
I've been browsing all over, but have been unlucky in my search for the moment.
I recently bought an android smartphone on aliexpress and it's a budget phone with moderate specs.
But I'm unsatisfied with the current factory performance of current OS, so I'm searching to replace it with something I might optionally tweak over time as well, but any active custom rom will do.
I'm specifially using the MTK6899 cpu on this phone.
I had to aswell already factory reset to fix storage capacity issue, so not a good sign to begin with either.
I'm really looking for any answer to clarify my quest/research in understanding the possibilities to port this phone to a different rom.
AFAIK Mediatek's source code for their chipsets isn't open source, hence developing Custom ROMs suitable to a specific Mediatek chipset is impossible.

Hmm that's a bummer, if only I knew this before acquiring this phone, right?
So should I aim at finding one for another mediatek chipset?
Or will there be too many issues caused by incompatibility?

As I can see you didn't get it.
A Custom ROM basically doesn't depends on Android device's chipset, it only matters with regards to being a 32-bit or 64-bit chipset.
Developers of a Custom ROMs claim their Android ROM is oftentimes faster, more efficient, and use less memory because
they ripped out useless garbage, such as OEM/ carrier installed apps ( AKA bloatware ) or
they optimized the kernel. For example, an undervolted kernel can provide a much better battery life than the stock one.
That's all.

Is it possible to use a recent Kernel in tab2?

I was wondering if is it possible to use a recent kernel in tab2.
There is a Linux system (Maemo Leste, based on Devuan (Debian without systemd)) that runs in a Motorola Droid 4, that uses a recent version of the Linux Kernel (5.11) and has the same CPU and GPU. https://leste.maemo.org/Motorola_Droid_4
Would it work in tab2?

Why don't you try building a rom with 5.11 one ?? As you can see in the thread above, camera doesn't work due to 3.4 kernel and also wifi was an issue earlier but it is fixed now. Something or the other might not work but maybe the rom would boot up atleast !

Well as far as Android is concerned, in the future, we might get Android 11 with the 5.4 android common kernel. That won't be a easy job to make though.
To port to mainline (5.15 kernel or newer) is kinda possible but it requires even harder work, indicated by the fact that there is only a finger-countable few of those get to this stage, and even if you get it, some features won't work.

How to install LineageOS on Limbo ARM emulator?

Hello, how to install LineageOS on Limbo ARM emulator?
I want to do some development work that needs rooted Android system compiled with ARM instruction sets. I have used several Android emulators on Android, but they all have various problems.
I don't want to use Android x86, because it is incompatible with ARM apps and will cause great performance loss.
I do not intend to root my smartphone, because I do not want to expose my smartphone to danger.
try finding a iso for it!
or tutorial for it?
I have searched for it in the web, but there are no ISOs or tutorials for it.
there is lineage os 14.1 x86 builds. or other android versions too! but i dont think they will work on the arm version. i used to use boschs back in the day with my old tab. i havent used emulators since. you could give it a try. just search android x86 on google. i remember there used to be versions of limbo that emulated x86. anywho hope it works
Running a custom Android OS ( here: Lineage OS ) in an Android based emulator like Limbo requires you need to install an Android version with a KVM enabled Kernel.

i dont know. maybe you could try gsi's? using dsu sideloader? go search it up. the sucess rate on locked bootloaders and non rooted devices is very low but its worth a try.
IF YOU VOID YOUR WARRANTY SOMEHOW dont blame me please... alr got alot going on in my life rn
Thank you for your help. It seems that I have to abandon this idea currently.
By the way, Limbo x86 emulator runs as slow as a PC in 1995 on my device. (I'm using MediaTek Dimensity 810 @ 2.4 GHz with 8GB RAM.)

yeah its super slow. better abandon this. and lineage os 14.1 native bridge never worked for me. meaning that some apps wont work at all e.g. some games and will crash.
According to my research, the performance of a virtual machine in Limbo x86 emulator is equivalent to about 4.12% of the physical ARM smartphone's performance.
I said that:"I have used several Android emulators on Android.", these emulators don't have performance problems on my smartphone. These emulators are:
VMOS / VMOS Pro - You need to pay to become a member to use rooted virtual machines. Its theory is similar to Anbox.(Off Topic: Perhaps the Anbox development team can make an installer for Android.)
VPhoneGAGA - You need to pay to become a member or watch advertisements to use rooted virtual machines. Its virtual machines contains advertisements unless you are a member. The theory of this software is to rewrite linux's C functions.
F1 VM / X8 Sandbox- You need to pay to become a member to use rooted virtual machines.
V8 Box - It's free and ad-free. It provides rooted virtual machines for free. But at present, this software only supports Android 5.1. This software is only available in Chinese.
