Hello to all,
For t715 with Exynos processor, it is a 64 bit ROM on XDA?
I don't find any thread with...
Anyone know about this?
I appreciate any feedback.
Hello,
While the Exynos processor is compatible with 64bit instructions, Samsung never enabled it from the kernel. No device with this processor was ever released with a 64bit version of the kernel, thus, all custom ROMs are forced to use what's currently available: 32bit ARM instructions.
Since the processor first got used inside the Galaxy Note 4 (which was launched on Android 4.4, before Android supported 64bit instructions) Samsung had to use a 32bit kernel. It was not worth the extra effort in rewriting the entire kernel from the ground up just to make it compatbile with 64bit instructions. And now here we are, 6 years later.
Hope that cleared up any question you might have had left. Have a nice day!

For a long waiting, Android 8 is finally here.
And ZR has working for 4 years
I wonder if our phone will have an Oreo update?
It would be cool, and a chance to revive our phone.
Thanks.
I read somewhere that it will only be available for devices with 64bit processors, so i highly doubt it

Some developers are working in it.
this is good news

Is it really? I mean, the Exynos variant is 64 bit capable, is it not? I know Samsung never did anything with it's still a 64 bit chip

Being capable is one thing, Being disabled in boot-loader level is another. Yes the 5433 Can handle 64bit. However in Note 4s case. The bootloader is locked to 32bit, which means the kernel is locked to 32bit, which means its impossible to run 64bit libs on the OS. even if you somehow managed to source 5433 64Bit libs (which is impossible unless you are samsung)
Take another example. my other device the J530F (Galaxy J5 Pro) it has an exynos 7870 which is a 64Bit enabled chip, However the bootloader is Also 64bit capable (which means the kernel is 64bit which it is) so a device like that, it could be debatable that it could get 64bit if someone we source 7870 64bit libs. But Note 4s case, its just not possible. regardless of android version

Aaah, got it. Thanks for clearing that up
I guess even if it was possible, there's not much you would be able to actually do to take advantage of the 64 bits with just 3 GIGs of RAM, right?

Aside from RAM , the main benefit would be using 64bit apps, so Bixby voice/vision for example.

Well.....we might have a chance of getting Google Camera to work on the Note 4 if that's possible

Hello, sorry for late question. May I ask how you realized that it's a 32bit-only bootloader?
I am trying to mainline this device, and there is support for exynos5433 on the mainline kernel. However it is only in the arm64 folder, so if the bootloadfer is 32 only i don't think its possible to mainline. thanks!
Is there a way to leave the firmware as it is and only increase it to 64bit without changing much?
no, thats not how that works at all.

The only possibility of getting to 64-bit is if motorola releases 64-bit source code after launch, and then someone creates a custom rom using it. This actually happened with the original Moto Z Play, so there is a chance. But we're not there yet.

Is it possible that it gets 64bit with the pie update?

Likely only if a device originally shipped with the 64 bit OS (e.g. G6 Plus). If you've got the G6 with a 32 bit OS, the update would likely be 32 bit, with you requiring custom development for a 64 bit custom ROM. From what I understand, moving from 32 bit to 64 bit may need a device wipe, which a lot of users (especially non-XDA or non enthusiast users) may not understand or happy with if that was mandatory for a system update.
What's the point in having 64bit on this device?

As far as I know, mainly the reason for wanting 64 bit on the G6 would be to use certain apps that are only 64 bit (e.g. Google Camera and in this case, fortnite). The G6 has 4 GB of RAM so the memory addressing advantage wouldn't be in use (unlike the G6 plus which can include up to 6 GB apparently), though could be argued you may get better performance from 64 bit. However, drivers may have to be re written or modified from the 32 bit system to work on the 64 bit, even if you could flash the 64 bit custom ROM, there may be bugs.
As a non-developer, it would be my assumption that the bootloader and vendor files would have to know how to interact with 64bit parameters. Despite our hardware supporting 64bit, the underlying software must support it as well. Like others have said, Motorola would have to release the source or build it for us.
I dont know a lot about this, but i think the Moto G5 Plus community got it.
They did the firmware 64 bit despite the fact that Motorola didnt do anything
https://forum.xda-developers.com/g5-plus/development/dev-64bits-t3708091
@dejello is working on 64bit support. last i heard he had a 64bit kernel working in TWRP with a working display.
Xiaomi has recently said that Redmi 6A will neither get Android 9.0 Pie update nor MIUI 11 update. So it's only a matter of time before they stop providing updates at all, including security or bugfix updates.
So, has anyone been trying to develop a custom ROM for this device? To inform everyone concerned, it's kernel sources have already been released. Also, I'm no developer, but due to the fact that this device supports Project Treble, it shouldn't be too hard to build a ROM for it. Or at least someone could try and build an arm64 version of the ROM, if possible (This device has a 32bit ROM running on a 64bit processor).
So I politely ask the developers present here on this forum to try and make a custom ROM for Xiaomi Redmi 6A. We'll all be thankful.
i don't know how many mediatek devices out there have custom roms, but i think it's not as easy as qualcomm devices to have custom roms.
i've tried many GSI images on my 6A and none booted, despite this device being compatible with Treble. Also i've read in some sites that it will indeed receive the miui 11 update, we just don't know when.
I really hope someone make an actual rom for our device, because this Treble and GSI thing is just an unneccessary ummount of hassle and the result seems to be rather buggy judging from all fixes and patches you have to flash after flashing a GSI.
Anyone can port Pie 9.0 rom from Oukitel C15 Pro Helio A22 chipset?

As far as I know, this device has a 64 bit processor, yet the ROM is 32 bit. Any idea why is it like this?

it's an ARMv7 processor, if you want to test GSI roms you need an ARM/A only GSI image. I've finally been able to install a custom GSI image that works properly, albeit with minor bugs. Still a proper custom ROM is unbeatable in my opinion.

Correct me if I'm wrong, but as far as I know, this device has Helio A22 chipset, with Cortex A53 processor, which is ARMv8 64bit.

https://en.m.wikipedia.org/wiki/ARM_Cortex-A53
Only the ROM (including the kernel and everything) seems to be 32bit.
Flashing an arm64 GSI wont work, because other partitions like vendor will still be 32 bit, and thus make the GSI incompatible. We'll probably need a real custom ROM with all its components compiled as 64 bit.

If the cpu has 64bit support then i don't know why they didn't use it. But so far we only have ARM GSI as an option for custom rom.
translate: this is a tutorial made in Indonesia that makes the vendor redmi 6a / 6 certus = cactus / cereus to boot the arm64 rom, the rom uses the nusantaraos rom https://nusantararom.org/
edit: i put wrong link, now that real video
I have the 10.5" version of the Samsung Galaxy Tab S (sm-t805 chagallte) and I am searching for a custom rom. I have already installed twrp and the IronKernel+IronRom. But even when doing simple things such as drawing, there is some lag. I know that this tablet uses a x86 architecture and may not be as fast as the following tab s models, but maybe there is something that can satisfy my request. Also, some guide is apprecciated. P.S. I live in Europe, so I have the Exynos processor instead of the SnapDragon.
I use Lineage OS vanilla on my T-705 , its really smooth , I also have the exynos 5420 version

Thanks for your reply. I installed Lineage Deathly 14.1 and it's fantastic! Deathly adiutor is an awesome tool.
