Rom change

Hey guys I'm new to flashing ROMs and xda developer thread so I apologize in advance for any blunders about where to post this.
I've got a few questions.
1) Can I install the stock ROM of a device made by the same manufacturer as my phone ? The purpose being getting the latest android version. Given that the device is almost identical to my mine. The only difference is in terms of RAM, Camera and the number of cores of the cpu. Otherwise the cpu architecture is the same.
2) if yes, will I face performance issues since the processor of the target device is slower?
3) if not, is there a way to port its operating system manually to be compatible with my phone ?
My device : HTC 626g+ running android 4.4.2. 1Gb RAM OCTA core 1.7 GHz cortex A7 processor. Mediatek chipset. Mali 450 MP4 GPU
13 MP main camera. 5 MP secondary.
Device I want ROM of : HTC 626s running android 5.1.1 upgradable to 6.0.1. 1.5 GB RAM.
Quad core 1.1 GHz cortex A7. Snap Dragon 210 chipset.
8 MP main 2 MP secondary.
Any help will be greatly appreciated.

64bit Rom

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

@dejello is working on 64bit support. last i heard he had a 64bit kernel working in TWRP with a working display.

[DISCUSSION] Has anyone been trying to develop a custom ROM for Redmi 6A?

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/

Has anyone got LineageOS or anything later than Marshmallow working on this amazing piece of hardware yet?

There a LOS rom for Mi Pad 2 (same SoC: x8500). I'm currently looking into booting Android N on Z8300 (Chuwi Vi10 Plus) and also Mi Pad 2, once I get a new tablet.
You can consider signing this petition asking Lenovo to release the N kernel source (currently no N kernel source is available): https://www.change.org/p/lenovo-kernel-source-code-for-lenovo-yoga-book-android-n-7-1-1
You can also reach out to Getac and Medion and ask them to release the kernel source code for their devices using the Intel Atom Cherrytrail platform.

Yoga tab3 pro internal memory
Hi guys,
I got Lenovo yoga tab 3 pro 4Gb memory 64Gb hdd. The problem I've got is the internal memory keeps getting full even though the apps take only about 4 GB and I tried to clean the cache and whatever I could but it still shows that OTHERS occupy 52GB
Lenovo forum is useless as nobody gives a f about your problems with their devices.
Anyone got a problem with internal memory space?
Any suggestions?
Thx guys

Was a Lineage OS or any FOSS ROM for this ever made?

Is there a more updated version of this? What version is this for?
