[DISCUSSION] Has anyone been trying to develop a custom ROM for Redmi 6A? - Xiaomi Redmi 6A Guides, News, & Discussion

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://www.mediatek.com/products/smartphones/mediatek-helio-a22
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/

GSI trebble roms VS roms from mix2 roms forum category?

hello, i have seen that our MIX2 is listed under supported phones
https://github.com/phhusson/treble_experimentations/wiki
more infos here:
https://www.xda-developers.com/flash-generic-system-image-project-treble-device/
anyone have tried those Pie gsi's? are they working with no bugs? what's the pros and cons?
And by using those GSI do it mean that you can use newer firmwares and hardware drivers then the ones shipped in our custom roms?
thanks !
In theory will the Mix 2 be able to tun GSIs. All it needs is at least a Oreo Vendor Partition and a Recovery who supports Treble (A/AB). I will test it this Week but i would wait for official Pie from Xiaomi to have a updated Pie Vendor Part which should solve many Problems (Like possible non working Hardware (NFC, Camera, Baseband etc.))
I've been using the unofficial Pixel Experience GSI for months. It's been way less buggy than any device-specific ROM - would definitely recommend.

Have you or anyone else booted a Android 10 GSI on Chiron? I've had no luck and tried 58 different things. Guessing we need a different boot and vendor than we used on Pie maybe..? Idk I see mix 2 isn't oem supported. I'm dying to boot DerpFest. Found a Aonly 64bit GSI over on telegram about a week ago. I sure hope we will be able to use 10 GSIs. Would be great!

Galaxy tab a T510 Custom Rom

Now that we can unlock the bootloader and root the galaxy tab a T510 It would be cool to see custom roms developed for it
I would love to see AOSP android running on the T510
Is there anyone in the custom rom development able to do
Does nobody want to see a custom rom on this device
I'm Interested too !! A debloated Rom please !!!!!
I posted my TWRP build here, so I'm hoping that enables more custom ROM development for the SM-T510. Unfortunately, my initial attempts with GSIs were unsuccessful, even with NoKnox to disable most of the Samsung security features. Seems I'm still missing something, but Galaxy S10 owners have had some success after making minor changes to the generic image.
Has anyone tried this GSI guide for the Galaxy A8, which shares the same Exynos 7885? It's got the rw-system.sh fix noted above.
I may purchase.this very soon. I have high hopes for this device getting lineage
Would love to see a custom firmware release as there's only a 32 bit version of android and I'd like to get 64 bit support. Great little tablet aside from that downside
Interesting note here in the @phhusson's Treble Wiki:
Why should I use GSI for A/B devices to some A-only devices? : On Android 9, Google changed the requirements and all devices shipped with Android 9 must use "system-as-root". Before this change, only A/B devices were system-as-root and GSI name was separated by A-only and A/B. For this historical reasons, you have to use GSI for A/B on the devices shipped with Android 9+.
So, I'm thinking that we should be using ARM for A/B...and not many custom GSI ROMs are built for that target.
Okay, I had some limited success with the latest AOSP 9.0 GSI build from @phhusson. The note above from his Wiki was spot on: We need an ARM A/B configuration for the SM-T510/T515...which is unfortunately a rare combination. You must also this updated /system/bin/rw-system.sh script. I used the build with GApps (system-arm32_binder64-ab-gapps-su.img.xz), but this generates a ton of error notifications because the device is not Play Protect certified.
We're getting much closer, though.
Okay, here's a quick-n-dirty custom ROM build based on the AOSP 9.0 GSI mentioned above: https://forum.xda-developers.com/ga...om-nexus-stock-2019-galaxy-tab-10-1-t3944222/

Samsung Galaxy J7 Prime (SM-G610M/DS) Android 8 or Newer 64-bit?

Hey there!
Do u guys have an Android 8 or Newer 64-bit for SM-G610M/DS? Can't find it anywhere. Is LOSQ compatible?
I am using J7 Prime SM-G610F. You can go for Treble ROM. Right now I flash Treble and flash Arrow ARM64 a only. Everything works smoothly like a charm.
Cheers,

I am using Treble Arrow 9 ARM64 a only ROM. OneUI based ROMs have some issue about contrast. 80-90% Gray turns white. That makes everything too bright.

I am writing an article to explain how to download and install Treble project on J7 Prime (especially SM-G610F).
For quick answer, you can check all the links for Treble and many useful stuff here.
Advantages of Treble ROM:
1. I can have many choices of ARM64 Treble ROM with quicker and contunuing updates. I could not find good ARM64 Dedicated ROM for J7 Prime for daily uses yet.
2. I experienced contrast issues with OneUI based ROMs. 80-90% Grayscale turns white. Most Dedicated ROMs for J7 Prime are OneUI based ROMs. Non-OneUI ROMs are discontinued.
3. With Kraken ARM64 Kernal for Treble, Everything is very slick. But when I flashed Kraken ARM for Dedicated ROM, everything is very slow.
4. If you want to try Android 10 (Quack) for now, you need to flash Treble. However Android Q is not stable yet.
5. For A/B Treble phones, Android updates are seamless and the suppliers give support for firmwares of Treble project. (J7 Prime is A only)
Disadvantage of Treble ROM:
1. Easy to get your phone bricked and bootlooped at logo. You can switch back to Dedicated ROM if you want.
2. LED light on top of the phone when screen off can't be activated while charging. I still cannot find patch to fix this yet.
3. Open Camera app in Treble ROMs does not have camera functions such as panorama, etc. I still can't flash any Treble OneUI ROM and get this to work, so I have not idea what happen in OneUI's camera app.
4. Flash GAPPS need to resize /system partition for J7 Prime phone.
5. Flash Magisk needs a bit more work to get some functions to work.
6. Treble project for J7 Prime and related phones has been discontinued by the original author. So there will be no update soon or never. This makes the future Treble ROMs may not be flashed and works well.
7. Treble ROMs are much bigger than Dedicated ROMs because Treble ROMs are supposed to install on any phones that support Treble project. But Dedicated ROMs are specific to one or series of the same model.
8. Treble ROMs don't come with firmwares for the phones. I need to find and flash the phone firmwares by myself. Sometimes wrong firmwares cause malfunctions in phones. I am nothing developer so I have no knowledge about this stuff. :laugh::laugh::laugh:
9. More chances of getting the phone bricked. In contrast to Dedicated ROMs that brilliant developer team supports.
For me, I prefer ARM64 performace so I plesantly take the risks. Right now my J7 Prime is apparently slick and zero random reboot.
Cheers, :highfive::highfive::highfive:

Question about lack of A6 ROMs

After spending a couple of weeks searching for LineageOS for the A6 (not A6+), I've discovered that there's very little support for this device. Why is this?
Probably smaller userbase if we compare with other devices. Furthermore many things are common for most of the Exynos 7870 devices. Lack of roms shouldn't bother you, because we have GSI, so in this way you can run Android 11 and even Android 12 on A6.
Also, part of community is active on Telegram.
My A6 works very well on Lineage R mod (Android 11).

So it's not so much as ROMs for the A6 but instead more GSIs for the A6? If I'm understanding correctly

1. Go to custom recovery (recommended will be OrangeFox R11.0).
2. Wipe partitions: cache, dalvik, data, vendor, system.
3. Choose GSI from link above (I can recommend Lineage R mod but you can try different ones; choose arm32_binder64 vndklite builds), download, extract and flash it as "System Image" through custom recovery.
4. Flash vendor for A6 via custom recovery.
5. Optionally flash any custom kernel for A600X.
6. Reboot to system.
If you want typical OneUI rom then use RadicalQuack or JynxOS.

sorry lineage R mod support for A6+ S605G ?
Getting confused with the different versions for A6 / A6+ etc.
I have an SM-600FN model which I think is A6 (not S or +).
It's currently running stock 10 - is there a good 64bit ROM for this? I was thinking it'd be easy to pick out but it is old... I could only see an Android 6 64bit ROM?

For A600FN pretty stable arm64 rom is RadicalQuack. arm64 GSI is also possibile to run on arm64 vendor, but it's not perfect (unstable).

hey, ive been trying to follow this for a while now but it doesnt work at all for me. im on an a600-fn device, and the only thing thats worked for me here is radicalquack, but thats android 10, and im looking for a way to upgrade my phone to android 11 or 12

just to clarify, the arm images werent working either, so its not just working because im using the right architecture

It brought you to download mode probably just because you used wrong architecture of GSI. Vendor from my previous post is intended for arm32_binder64 (A64 - not arm64) vndklite GSI images.

i just used a lineageos 18 gsi image and the treble vendor, but it turns out that while it did get to the boot screen that says lineageos (which gave me tremendous amounts of hope), it would NEVER boot up, so dont do what i did i guess lol
currently, im trying what nqnxev told me, and it should hopefully work

Android 12 works fairly well on the same vendor, but flash this recovery at first, because older OrangeFox can stuck while boot with Android 12.

this phone has a 32-bit vendor means nothing 64-bit won't work on it. Unless xiaomi will publish 64-bit vendor or make the MIUI 12.5 update 64-bit but i don't think they will.

I have good news for you there is a 64 bit ROM compatible with the redmi 9C it is CR-DROID under Android 11 the disadvantage is that to flash this rom you must already be under MIUI 12.0.10 . there is also a problem with the network which is fixed by installing a magisk module (hotspot) and there is low sound during calls. And it takes the NikGapps.I will make a post for the tutorial
