what about an android 10 port for nexus 9 wifi - Nexus 9 Q&A, Help & Troubleshooting

hello iwas just wondering if ther e could be abring up ofan android 10 port for nexus 9. as hte are other port bring up for ohte older devices and tablets. Jus twondering if its possible ornot.

Vartom had commented that there are driver issues with the Nexus 9 as it is and making it work fully with Android 8.1 is difficult as it is. It's likely it would be even more difficult to get things working with later versions without Treble

It would actually be fairly easy to build a recent AOSP for N9. In particular, the master branch of AOSP has some really cool pieces in place -- recent version of mesa3d, drm_hwcomposer, gralloc_gbm.... the only parts of the N9 that likely would create trouble would be the cameras. But you can't really use the cameras on a tablet anyway because you look like a moron doing so.
Note that Treble is NOT a requirement for building AOSP for N9. Previous poster is confused because its a requirement for devices that FIRST SHIP WITH certain versions of Android, in order to qualify for inclusion of google blobs. This requirement does not apply at all to N9 for THREE reasons;
1) No need for certification because you aren't trying to sell it.
2) N9 first shipped with Android 5.
3) Nothing applies to custom firmware.

Or now Android 11 for Nexus 9 ???!!!!

How can I create a rom for Huawei P9 or Samsung Galaxy S7 (Edge) from Stock Android

My last and my current smartphones were nexus devices. Since google revealed the pixel I thought about other smartphones. But I don't like update speed from non-google companies.
How difficult would it be to convert the current Stock Android (for example android 7) to the Huawei P9, OnePlus 3 or the Samsung Galaxy S7 or any other top device.
And how much time would you need to support also the curved Display from the Samsung Galaxy S7 Edge or to support the notification button from the OnePlus 3 and the fast charging.
To myself: I would say that I am quite good at Java but not in a professional way.It is just a hobby.
In general: If I buy the latest smartphone of a company like Huawei, Samsung, OnePlus or LG would it be possible to convert the current Android version to my device? How much time would I need for that if I only want the Stock Android functions and the fingerprint sensor (Cyanogen features are not needed) and how long would I need if I also want to support the device specific features like a pen or a curved display?
How dangerous would that be? Breaking my device would be pretty easy right?
If that is possible how do I convert the Stock android to my device?
Thanks a lot

short answer: very difficult. Huawei uses custom SoC from HiSilicon, and the specs for these chips is not published. similarly for Samsung devices using Exynos chips. Samsung phones running Qualcomm have a better chance.
if you want to learn to build AOSP (or something like CM), start with the AOSP documentation, then the CM wiki. Or go to the device forums here and check if someone has already started progress. for Huawei and Samsung (exynos), it's a long journey.
it goes well beyond knowing Java.
relatively speaking, modern devices are tough to permanently brick as long as you don't touch the bootloaders.
Thanks for the answer

Tutoring how to port a device to a later version of Android?

Hi
I'm a programmer with around 10 years experience and wanna get into ROM/Kernel development. But its pretty hard since I've been doing very different stuff (mostly Java/Xamarin stuff)
More precisely I want to learn how to port Android 6/7 into the Xiaomi Mi Pad 2 - I own this device and there are only buggy (Kernel/driver bugs) opensource ROMs running Android 6 (note that this is an x86 device).
So I am looking for tutoring to learn how to do it - think of 2-3 hours weekly via Skype or something similar (for money of course) Anyone up to this? Or am I looking in the wrong place?

Phone for Lineage OS.

I am not sure what section to post this question in and I am not aware that this question has been answered.
Where to I find a list of recent phones or tablets suitable for Lineage OS? The LineageOS own site is a mix of really old phones with more recent ones and omits all non official ports.
The question is actually quite simple: suppose I want to buy a phone or a tablet today to install LineageOS. What are the options?
The requirements are:
-the device should not be too old (issued in 2017-2018), or I can't buy it new
-it should support Lineage 14 or 15
-Lineage should be installable on the current version, ideally without needing to register as a developper by the manufacturer.
The latter is more tricky than it seems. For example, the Samsung A5 is officially supported by LineageOS 14, but there is no LineageOS 15 rom available. Current versions come with Android 8.0 and cannot be downgraded to LineageOS 14. Besides, Samsung added extra security on their bootloader which makes installation a real pain.

Why not just shortlist a few devices you like and then checking whether they have good dev support?
Samsung is the toughest to get a bug-free lineage os rom, so strike that
OnePlus has good dev support and some Xiaomi phones too

Thank you for your answer.
I did not consider OnePlus, because their phones are only available for a short period of time. When LineageOS is available, the phone is usually out of production. Xiaomi, I don't know about their phones.
Do you know if OnePlus and Xiaomi allow installation of alternatrive roms without requiring an unlock key from the manufacturer?

OnePlus doesn't require a key from the manufacturer. OnePlus 6 or 6t should be a good bet if you don't mind the notch . However, unlocking a Xiaomi bootloader may be time-consuming since you need a code and it can take time to get.
EDIT; You can't go wrong with a Google Pixel 2XL , all roms will work seamlessly

So, Xiaomi would be a second choice. I don't really want to have to beg the manufacturer for an unlock code.
I checked about the OnePlus 6 and 6T. No real development yet on 6T, since the phone is not publicly available (expected). LineageOS 15 does not appear to be maintained any more on the 6. Bummer.

I checked the Google Pixel 2 and 2 XL. There are difficulties with these phones because of encryption, but they can be solved. Lineage is a special build that comes with gapps pre-installed. I dont want gapps at all.
Thank you for your help, but I still don't have what I am looking for: a phone, reasonably recent so as to be available new, with a reasonably usable Lineage OS 15 installable without too much trouble.
I also asked about a tablet, but that seems even more difficult.

Is anyone still using the Mi Pad 2?

Hello, I still have my Mi Pad 2 (16GB) laying around and i've been thinking about replacing its battery and then install some sort of alternative OS such as Ubuntu, Chrome OS, Android x86 etc... I saw some topics here and on other websites but only a few people actually got those OS's working but didn't provide any instructions whatsoever.
Is someone still interested in this device? If so, any help and support would be appreciated.
Yes, I am still using it. I had already replaced the batteries once.
Trying to find a good custom ROM.

Is it easy to replace the battery? I'm thinking about getting a new one. Btw, what ROM are you using at the moment?
Yes I am ,but i flash win10 2004 . and Improved heat dissipation,Now, the only issue is the shortened battery standby, but other than that I'm pretty happy with it!

I'm also willing to try Windows 10 2004, but a lightweight version because my Mi Pad 2 is the 16GB version. How did you install that on yours? With a USB dongle with USB stick and keyboard like a regular computer?
Also, how did you improve heat dissipation?
By the way, does anyone know if it's possible to desolder the eMMC and replace it with a high capacity one? Like 64 or 128GB?
I still use my Mi Pad 2, mainly for reading. But been looking into bringing up Android N to this tablet (there is at least one Intel Atom nougat kernel source available, which might come in handy) and also around 3-4 different tablets running Nougat on Intel Atom (so we can try to use those blobs). Bliss OS is an option as well (as per the guide(s) on this forum). One approach could be to assist the Bliss OS team in squashing the bugs for the Mi Pad 2. If you want to discuss this further, feel free to let me know.

I'm a bit "desperate" to have a good OS available for this device because otherwise it's basically a paper weight for me. Stock MIUI was always flawed and slow and in my case Windows is pretty limited since I only have 16 gigs. And yeah, I'm available to discuss this further, it would be a pleasure.

Have you ever tried the AOSP rom (it's seems to be a developer rom from Xiaomi) for Mi Pad 2?
I'm currently using MIUI 9.6.2.0 Mod from LVware it's working fine.
The only Android N kernel source for Cherry Trail devices available is the Grandstream GXV3380 http://www.grandstream.com/support/resources/?title=GXV3380 (scroll down to GXV3380 GNU GPL). Grandstream writes its rom is Android 7 based, so the kernel source must be Nougat based (I only write this, because a Cherry Trail nougat source has never been released, so this is huge. I even think it is able to compile based on the archive contents). I only came by this by searching for Cherry Trail devices on Geekbench Browser. Would like to compare this kernel source to the Lollipop Mi Pad 2 one.
In terms of an Android Marshmallow Cherry Trail kernel source, I could only find the Panasonic Toughpad Android 6 (PANASONIC FZ-A2A): https://panasonic.net/cns/oss/tabletcomputer/FZB2D001.html .. It's worth mentioning that Amazon has made the Amazon Echo Show (2nd Gen) kernel source available as well (5.5.3.9-20200618.tar.bz2), but I think it's Lollipop based: https://www.amazon.com/gp/help/customer/display.html?ie=UTF8&nodeId=201626480 (scroll down to Echo Show (2nd Generation). The Nougat kernel source might be released, as the latest software version available is 655636620 (https://www.amazon.com/gp/help/customer/display.html?nodeId=201602210) and according to Wiki the 6.x.x.x builds are Nougat based. I know it's confusing, you can read more about it here: https://en.wikipedia.org/wiki/Fire_OS#cite_note-4
In terms of blobs, there are plenty of devices to borrow from. Medion has 4 tablets that have been updated from Lollipop -> Marshmallow -> Nougat. The same with Getac, which has two models the MX50 and the ZX70. Lenovo has a few Cherry Trail devices as well upgraded to Nougat, which can be borrowed from.

Yep, I've tried the AOSP ROM but it gets really slow after a bit. It's almost impossible to multitask because it can't handle more than 2 apps. Never heard about that MIUI ROM though, do you have a link for it? is it good?
About the sources i'll be completely honest. I have limited expertise on this subject but seeing all that makes me think that it's not that impossible to make a good ROM for our device (am i wrong?), so what's limiting us? People with knowledge? More sources? What's the next step?

holy ****ing **** I know exactly what you mean. windows 8 does it. windows 8 is great.
i've been messing with 8 on it, and it's literally orgasmicly good. 10 is still my main OS because some drivers are missing, but the whole of it works really well.
oh, and using gibson's inspectre.exe to disable spectre and meltdown protections was THE thing to finally get the performance that seemingly disappeared. thats because it did disappear! also seems to help with RAM usage enormously
and I cut the plastic insulator between the motherboard and the rear case. filled in the gap with a thermal pad pretty much right on the CPU. 2.24 GHz base clocks now baby!
and this CPU is around a 7W TDP for anyone wondering. intel says 2W SDP, I say 4W SDP is probably closer to reality. 2W is at the base 1.44 GHz tho, but mine is at 2.24 GHz all the time.
I still have my 2GB RAM 16GB internal MiPad2 and working with shortened battery life and some limited app functionality (G.Play doesn't work/update for eg).
I want to use it primarily as a book/manga reader as well as a media player of sorts.
I saw the recommended custom ROMs list here but any advice on which is ideal for this device based on its limited hardware?

i installed a light version of windows 10 on mine and it works surprising well. I have around 8gb to play with
That's cool! Performance is ok?
So would app installation then be via the Microsoft Store or can you still install via Google Play?
Are the instructions for the Windows 10 Lite flashing detailed somewhere on this forum?

Hello,
can you really install Windows 10 on Mipad 2 2 / 16Gb based on Android?
I have a Mipad 2 2/64 based on Android, and I want to replace it with Windows 10, would you like to share the method with me?
I still use this little tablet as a second screen/device playing video's on the desk when im working on my laptop. The screen is still really nice: bright and crisp. Mine has Windows 10 installed which is barely useable, usually everything feels kinda slow, but it does work. The biggest problem was that it thermal throtteled after normal use, so what helps is if you do a cooling mod. It's not that hard, I cut a square out of the shroud thats covering the CPU and placed a thick thermal pad over the CPU so it touches the outer metal housing. This greatly improved CPU/GPU performance and solved the thermal issue. The housing doesn't even get that hot when you stress the tablet. It now plays video's no problem all day long, where it would stutter after while without the mod...
Don't expect any miracles though, it's still an Atom with a slow eMMC drive and only 2GB of RAM. Windows is just too heavy for it sometimes. A newer version of Android would probably be a better fit. What also helps is if you debloat Windows a little: https://github.com/W4RH4WK/Debloat-Windows-10

Performance is fine i guess. I think it gave a new life to my Mi Pad 2 even though i haven't been using it lately. App instalation is via Microsoft Store of course, or via .exe installers just like a PC.
I'm wondering if it will be possible to install Windows 10X on it. That would be very cool.
As for the instructions, i used an old tutorial from the Xiaomi forums to change from Android to Windows and then I installed that Windows 10 lite from Ghostspectre using a USB stick just like a regular PC

That's right, my 2/16 Mi Pad 2 is running Windows 10.
I found the link for the tutorial. Sadly it's offline, but Wayback Machine can open it just fine, except the pictures. Surprisingly, the download link is still online too but it's pretty big (7 gigs).
If anyone needs that, i can send the two links through PM

Will we get Android 11 or not. [MIUI based or Custom ROM based]

Yeah yeah. I know that we've seen the news about Poco and other 845 SoC based phone from Mi Series. Since the rollout of Android 11 on Pixel devices few days ago, there are many new features on Android 11 that I would like to add on Poco but since that Xiaomi promised us to get two major os updates (which are Android P and Android Q) it will most likely will stop on Android Q. But I have high hopes for Poco getting Android 11, MIUI based or not.
What are your thoughts about this?
Xiaomi has already cleared that poco f1 isn't getting android 11. It's not on their roadmap. We'll get miui 12 and maybe even 13 looking at the past experience. MIUI version are major upgrades for Xiaomi phones. Android versions like 9.0, 10.0 are practically just numbers to show off and that hardly adds any features on xiaomi phones.
I created petition on change.org for android 11.

You're on xda forums not miui. The one thing you should be worried about is device sources and community developer support not miui.

Yes I'm fully aware of that. But even though if I posted this on MIUI Forums, I still get the same answers from both Forums.
I highly doubt that someone can use blobs from MIUI 12 Android 10 to start from scratch to build a port to Android 11.
I forgot what device that was, I've experienced this coming back from 2018 when they used blobs from Android M to port and build Android N and that was stable enough they officially launched an official build.
Maybe my intuition was wrong or not, maybe someone from the Poco dev or even from the Poco community might wanna build and port Android 11 and might be one of the biggest breakthroughs of all time. Of course if it is stable enough to be a daily driver. I know that it is hard because of lack of blobs coming from Xiaomi's MIUI but maybe, someone will do it.

Yeah, Android 9 and 10 is kinda bummer because of lack of feature other than setting apps permissions which is great for me.
Android 11 has tons of new features like their improved privacy app features, the new smart device control quick settings which I really need because I have smart devices at home, improved notification and more.
I know these things can be treated on 3rd party apps but who wants to add more apps on their phone and maybe eat the battery on the background.

This is highly unlikely. Check piunikaweb they already mentioned there that a moderator from MIUI forums clarified that we'll get miui12, but unlikely to get Android 11. If you really want 11. Then wait for custom ROMS, but it may not be full MIUI Android 11 ports, rather from Pixel ports (one has already been released)

You misunderstand me. Even if they give android 11, the actual features don't arrive with the update. You will have to wait couple of years more to see native features of android 11 to implement into their MIUI ecosystem.
For example, custom DNS was introduced with Android 7.0 or 8.0 but it really came to xiaomi devices with MIUI 11 in 2020 year only.
On Xiaomi devices going from android 10 or 11 is as unsubstantial like changing security patch from august to september. Most of the people won't notice anything different.
We will 100% get Android 11 as a custom rom. As a matter of fact, it already is a thing. (Search xda) We won't get it officially as all non-pixel devices get only 2 android upgrades.
As far as XDA is there with active dev's updates offically from miui isn't a big deal for me ! Although our dev's are far more better than offical miui cause custom Rom are becoming far more Stabler than stock and in features . :fingers-crossed:
https://forum.xda-developers.com/poco-f1/development/rom-reloadedos-t4162237 11 is out for poco f1. Like i said, who needs xiaomis miui updates when you have xda. Long live the aftermarket software scene.
