Guys,
I have a CM802 Android 2.2 tablet that I would like to support external USB devices. My problem right now is that the default ROM doesn't seem to have USB host drivers, and I have no idea where to look. Can you guys point me in the right direction?
Thanks!
I don't know your hardware, but your android version should have no support for both usb host mode and USB otg. If you upgrade and hardware is ready, maybe. But very likely you'll need the kernel USB modules sources and a dev to compile them especially for that build. That's why on my se xperia x10 such feature is still missing ...
The hardware has support for it, and I don't care what version of Android I end up with, as long as there's support. I also don't mind installing them myself, but would like some direction as to where to find the modules.
have you tried going to the manufactures website?

You will need to compile a proper kernel with support for it. There have been a few on the site that have done it for a few devices but it is not an overly popular mod
Well, I have just seen a site where they sell the android 2.3 version of the same device which seems to have the USB otg support. In any case, the first step must be one upgrading at least to android 2.3...

the kernel would have been made to support it on that device. After building 2.3 from android source code I can say that it is not there by default.
Thanks, I agree that is not supported by default but maybe they had actually patched a kernel with those modules, though such kind of sites are not very reliable...

Can you guys link me to the modules or whatever? Again, I'm perfectly willing to build the kernel from source myself, as long as I can have a little direction.
Any help? Links, information, tutorials.. whatever you can give me would be awesome, Internet <3.
Oh, and sorry for the double post.
Lenovo is the only company to have released an Android Nougat update for an Intel Atom Cherry Trail SoC powered device.
If Lenovo releases the kernel sources for the Android N version created for its Lenovo Yoga Book (Lenovo YB1-X90F/L), developers can start working on Android N upgrades for other devices powered by the Intel Atom Cherry Trail SoCs.
Lenovo has previously released the Android Marshmallow kernel sources for the Yoga Book (https://pcsupport.lenovo.com/us/en/products/tablets/yoga-series/yoga-book/downloads/ds118515 Thus it shouldn't be a problem abiding by the General Public License v2 (GPLv2), which requires Android device makers to publish the kernel source code.
Please consider signing here: https://www.change.org/p/lenovo-kernel-sources-for-lenovo-yoga-book-android-n-7-1-1 . Thank you
True, we really Need to make Lenovo release the source Code, i hope you could edit your Petition by adding that also we Need Infos about how to use the source Code.
Greetings
I'm not sure that it would make a difference, but has anyone tried posting on their support forums or contacting them directly?
It might help our case to note that the device (the Android version, anyway) has been discontinued. I doubt we'll see any further official updates from Lenovo.
Take a look , Hope this will work for you:

Only via Facebook. Got this answer:
"Thanks for reaching out. Currently, this the only open source http://lnv.gy/2DMoObI we have for Yoga Book. You can keep an eye on the support website as it will be updated if a new open source will be released. Let us know if you have other inquiries."
Feel free to post the link to the petition on the Lenovo forums or even ask them via Facebook/scoial media. The more attention, the greater the chances.

WOW! I've passed this information along. Thanks a lot, this hopefully opens some doors
What did you do exactly?
UPDATE: It's another Marshmallow kernel source code. We need the Android Nougat kernel source code!

True, i open it and it was another MM sources, i will rewrite to them again, however, i figure it out how to use it, for example specially for yoga Book Windows owners, i tried to install Android distro (Phoenixos, blissos,......) but some Drivers were missing i mean no Sound, no Bluetooth,....... but today i understood how it work, in lib/Firmware we Can add this files in any Android distro to get some or all Drivers work, but im trying to figure out how to copy-paste them inside System.sfs under Windows enviroment :fingers-crossed:

Hi Users and Devs
im writing my test results here about dual booting and other operating Systems that i have installed them on my yoga book Windows Version and i will try to explain lot of Details about this stuff
First i will share the operating Systems and Details about what work and what not on yoga book.
Ubuntu(17.10.1), PhoenixOS(2.6.2 based on Android-x86 Nougat 7.1.1), BlissOS(10.1 based on Android-x86 Oreo 8.1.0), DeepinOS (15.5): no Sound, no halo Keyboard, no Auto rotating, no sensors, no Bluetooth, only Booting, Touch Screen, Screen brightness controling and WiFi are working
Android-x86(7.1.2), Openthos(Based on Android-x86 Lolipop 5.1): nothings at all
There might be a lot of other OSs that i might Forget to mention above, but i released why some Hardware cant work like Sound, Bluetooth,......
the main Problem is the KERNEL(the kernel is a big Collection of modules and Drivers that boot up our Hardwares as soon as we enter any Operation system), some kernels 4,9.x cant boot or wifi and touch Screen cant work, all kernels 4.12.x Support booting, touch Screen and wifi, all kernels 4.15.x Support booting, touch Screen, brightness controling and wifi
the only kernel that will make other OSs work like a charm and without any missing Drivers is buildslave kernel, this kernel came pre-load with most of Lenovo Yoga series + Yoga Book (for yoga Book Android users go to about tablet and check out it), the Problem is that i dont have a 100 GB (i will explain this later) ( in 22 mar 2018 they released the second Version of the Open Source Code for Lenovo YB1-X90F/L https://pcsupport.lenovo.com/au/en/products/TABLETS/YOGA-SERIES/YOGA-BOOK/downloads/DS118515 ) also depend on my Tests the kernel is only for Android 6.0.1, not for 7.1.1
i tried to build Android x86 from sources using Yoga Book Open Source Code from Lenovo but AOSP files are Need at least 100 GB with Additional files from Android x86 abot 20 gb, unfortunatly i dont have this big size of hard disk on my SSD
Yoga Book Android and Windows versions are 99.99% contain the same hardwares (0.01% are only the Keyboard shapes but also the halo Keyboard is the same in both) thats why it make my optimistic about running Stock yb Android Rom on Windows (Windows Version of yb used same bios as yoga Windows series, but yb Android Version use the same bios as yoga Android series does and all of yoga win and Android series based on Insyde bios)
Android yoga Book System based on Android-IA Project which is from Intel to allow Android run in Intel CPUs https://01.org/android-ia as yoga Book based on cherry Trails cpu
for Android yb users you can install Windows and other OSs on your device but you will force same Bugs above and you need to buy a licence key to get Windows updates on it (i only have yb Windows so i dont know lot of informations about this)
Windows yb BIOS contains a very basic informations and options (for example there is no UEFI and legacy option, there is also no ACPI enable;disable option, cpu overclocking......)
I believe there is a way to install Android stock in yb windows, i mean through reimagie the eMMC, for more infos, visit http://en.miui.com/thread-419845-1-1.html

What makes you believe the Android YB has an Insyde Bios? Not really, and as many tests demonstrated it not even has a proper ACPI implementation.

Windows BIOS dont support ACPI implementation, that because its hidden and it need to be edited through platform.ini editor tools (inside yb win version bios), the chipset on yb win and android (so far i know both are insyde).
after all you might be correct
correct me if i was wrong

It's quite the opposite...
Beginning with Windows Vista, the operating system supports only a computer with an ACPI-compliant BIOS
Android however does not use APM or ACPI directly for power management. Android instead has its own Linux power extension (wakelock).
That's why Lenovo uses a basic BIOS on those devices..

Fastboot is a Kernel feature introduced ages ago with 2.6.29 (2009) to allow asynchronous function calls (mainly to direct probe things like SCSI or libdata port scans). Nothing to do with the Bios.
Chuwi and some Chinese manufacturers use the special Insyde H20 Bios. Which the Yoga Book is not (by intention), the EEPROM is on a totally different basis.
@THE MAXIMUM POWER What is the best possible Android for playing around on the yoga book at the moment? I know, many things dont work for now, but if i want to try, would blissrom be the best way for now?

Hey Man !
I'm not sure if you're still following this; but, I thought maybe I'd better ask if you're still keen on development of this as I'm a kernel dev and have very recently migrated to this lovely new tab. So , I thought maybe if you're still into this, maybe we could gather a team to work on I'd be happy to help with the kernel part as far as my experience beside the medical school allows me to :laugh:

I currently own Samsung SM-T900 12.2" Tablet. I am running 7.x ROM.
I currently lots of free time and am interested in getting involved with ROM development. Is there a Tutorial / Guide on how to setup the Build Environemt either on Windws or Linux, download source code, build and then Test.
Thanks in advance.

The T320 has Pie and Q builds. I would download the sources for that and change it accordingly.

You mean, you have time and the knwo how to build a Rom? I need android10 on my Samsung tab pro10.1 wifi na2wifi/t520 pls :good:
Would love to see updated ROM for our beloved Samsung Tab Pro 12.2 (SM-T900). Current ROM is very slow at times and takes ages to load some basic browser tabs.
Yes, it would be great if we could get a fast, updated rom for the T900. I still love the hardware on this thing......
I was planning to buy this amazing device but i'm a little bit worried about the long term usage(atleast 2years) because of MIUI and Deminsity 1000+ .. so is there any chance of getting custom roms and gcam stable port? Because Redmi Note 8Pro is also on mediatek chipset but it has a lot of gcam port and custom rom support.
This is a phone made for China, I don't think there will be alot of custom roms. And I don't think there will be a gcam as well.
A Custom ROM basically doesn't depend on Android device's chipset.
The general approach to finding one is Googling for "YOUR_PHONE_MODEL ROM" or something similar, optionally including the wanted Android version. Try it out - you'll find what you want.
I will build rom for this line. There are international languages.

Very happy to see this and will be following eagerly @vandieutot . I really like my phone but the software is a big let down. Too many issues and workarounds required to get it working properly.
In preparation for this, could you tell me what will be required?
I currently have the K30 Ultra but its still standard phone. No root or anything else as yet.

I do not build anymore (no time) but I can offer a build server in case you need something to build rather fast.

If your rom safe to flash(no brick) im ready to help in testing.
If you can make a custom rom, that would be wonderful. Many k30u owners in China want it. There is a guy that made an Aosp rom for it, but he can't fix the bugs（fingerprint bluetooth）so if you can just help us, that would be great!
