Has anyone manage to install an usb audio board or usb headphones to ubuntu on hd2? Is it possible? I'm trying to update alsa drivers but haven't managed to solve this problem.
Is there a known way?
Yes, worked fine with new kernel update and modules. It detected as soon as i inserted the sound card even through usb hub.
However audio does not work for phone calls still. Exploring out still...
can you please direct me on where or how these updates could be make. Even external audio would be ok.
I've tried downloading any update i could get, but don't know how to enable sound as my external usb audio adapters are not yet recognised.
Yes... external audio is fine. I tried with a Microsoft USB Headphones and also with cheap usb sound card both are working fine...
Search with the string zImage-htcleo-usbhost-latest and download both zImage-htcleo-usbhost-latest and modules-htcleo-usbhost-latest.tgz
Search [Discussion]Linux and Android on the HD2 and you will get information about updating the kernel.
Cheers!
hello, i did by the following guide
Installing the latest Linux kernel image (zImage)
1) Download the latest Linux kernel image (right click, save file as)
1a)for Google Android
1b) for classical GNU/Linux based distros (Ubuntu, openemebdded, meego, maemo etc)
Be aware these build links are dynamic and will be updated once the Linux kernel source code is updated. See here for static links
2) Rename the file to zImage
3) Overwrite your old zImage file with the newly obtained zImage file
Installing the matching Linux kernel modules (.ko files)
1) Download the latest Linux kernel modules to match your kernel image
1a) for classical GNU/Linux based distros (Ubuntu...)
1b) for Google Android
2) Install the modules...
2a) in GNU/Linux
As root run
cd /
tar xvf /path/to/modules-htcleo-usbhost-latest.tgz
downloaded both zImage-htcleo-usbhost-latestt and modules-htcleo-usbhost-latest.tgz then renamed first one like the older one in the linux folder, then use the tar command in root console to copy files from the archive to /lib folder (or wherever they were put). After a restart i get some fatal errors during text load up of linux, something involving mod probe complaining about not finding something in /lib folder, modules.dep if i remember, then at GUI load i get another error "cannot update ICEautorithy file. When i click ok, i get the desktop loaded but still no sound plus now, no wifi or some other drivers.
I guess i did it wrong

can you please tell me in detail what I have to do to get usb audio working
in sound settings it shows me that there is no hardware????
i didn't manage to solve that problem.
i still have problems replacing the old kernel and modules, after reboot the phone displays some errors involving modprobe then iceauthority files. If someone could upload a newer version using this kernel or a guide to enable sound, it would be excellent.
ok, managed to change to a new kernel and modules with no problems but still.. no audio. By default (no other modifications) i have no audio devices in the hardware tab of "audio" in preferences. When booting up i can see the usb-audio driver loading up and my audio card is recognised as "usb headphones" or something like that, but when the graphical part of ubuntu loads up i can't see nothing related to audio.
Tried with both cheap sound card and logitech usb headphones, same result, no sound.
USB audio works on my Allwinner A10 tablet witn "Unofficial CyanogenMod 9 for many AllWinner A10 tablets" firmware from Christian Troy
Hello everyone! Thank you for taking the time to read my post, this is my first post, so please forgive me if I make any mistakes.
The PreLoader Driver for me is not working, at all. I run Windows 8.1.
Now, I've read to install it this way and that, and if you have a yellow exclamation point under device manager, I should be ok.
To run flashtools to make a backup of my firmware, I need a scatter file and the software doesn't allow you to do much of anything unless you select this file.
Fine, so I need to make my own scatter file, so I have the MTK Droid tools to make my scatter file.
Because my drivers don't work, I can't my scatter file and I cannot continue forward with this.
MTK Modem, Debug and Port drivers are all installed and fine and working correctly.
The Preloader and DA USB VCOM port drivers do not work for me.
Can anyone offer some kind of guidance? Suggestions? Driver issues you had and got working?
If I can get my firmware backed up I'll be more than happy to share and try to help tweak and such!
Thanks again for your help!
Anyone? Someone?
Please does anyone have the stock ROM file for apro q18 smart watch
Same problems too

I'm having the same issues too
Hi, I was searching the net and did not find anything, so maybe android gurus here can help.
I have Tesla style head unit based on autochips AC8227 processor cortex a53 quad core processor. I have android 4.4.4 installed on head unit, despite the fact it says it's android 6.0. I've rooted it or it was rooted initially, do not know, however I have access to the system files.
So what I need^
1) I need the best way to make backup of the firmware in case I brick something manipulating with system files.
2) I need to be able to redirect whole sounds to external USB sound card in particular to USB DAC based on PCM2704 with SPDIF output.
from searching the net I found that if I enter commands in terminal emulator:
su
ls /dev/snd
I'll get all sound devices recognized and used by android system and there should be USB sound system listed as well (if it's recognized of cause) However external sound card is not there. So I need to add modules (drivers) for it into the system.
Where to get them and how to prepare to be usable with AC8227 processor I have no clue.
Please help me to find solution to my challenging questions.
thanks
Hello,
I'm new with the Head Unit based on Android and If someone could help me answer some questions it could help me a lot.
I have this unit
In short:
Allwinner T8 board
MCU: T8.3.19-167-10-A43101-190504
System: V9.3.1_20181106.155925_CLC1-FD
Android 8.1
I'm trying to modify the ROM... and I don't care If I loose all the pre-installed crap inside.
So far, this is what I can do with this rom:
- Install APKs...
- Remove APKs...
- Connect via ADB over network
if beforehand inside the device I type "setprop service.adb.tcp.port 5555" in a terminal, then turn off and on the debug option in the developper menu. Thanks to serious manufacturers, all passwords seem to be shared between various if not all unit buyable over internet. The command and developper option trick must be done after EACH reboot, wich is fantastic behavior.
- Reboot to bootloader or recovery using adb
- In recovery, I can do nothing since there is no hardware key appart "reset"..., USB keyboard seem to not work either (I cry when I see the non reachable "mount /system" option ...).
- Use a hand made USB A-A cable to communicate with the device, when in bootloader. If "in rom" or recovery, adb or fastboot don't see the device.
So basically I can do nothing.
- I searched for firmwares, but I only find direct links to various site that provide update.zip or update.img or similar, but no flashable firmware from fastboot.
- If I found update firmware for T8 based board, my manufacturer version code (CLC1-FD) match none of those available here or on russian forums (AKW1-FD, JP1, TW2-FD,....).
- I can not use su (not allowed, setgid failed), to make boot and system image backup that I can eventually modify
- I tried KingRoot, Magisk (but I have no boot image ...) none work
- I tried "fastboot oem unlock[or whatever]", which just freeze fastboot and make it unusable until another reboot
So in the end, if someone know something about this hardware, if the another firmwares (AKW1-FD, JP1, etc) are compatible between devices, or if you know where I could ask for original firmware (oem image), or if it is possible to unpack the updates files to extract something exploitable (already tried for hours using basically all tools available like kitchen simg2img etc), please help me.
I have another device that will come to me, the ownice C800, but I think it will be the same problem. Unmodifiable over locked device.
I am working in a business where we need this kind of hardware inside a car, and we wanted to use one of the unit to make a proof of concept so we cannot afford custom hardware right now.
Thanks you if you had the patience to read this. Hope you can help.
Update and file recovery for Allwinner T8
Hello,

Do you know? How make file *.img rom from my Unit?

I am trying to downgrade my Nokia 5 to android 7.1. Currently, it's running on android 9. I tried this method.
https://forum.xda-developers.com/t/...oreo-to-nougat-for-bootloader-unlock.3893053/
But Windows PowerShell was unable to detect any device. So, then I searched and installed some drivers like these
But no work.
Then I found a solution in here
nokia phone not detected using adb via windows PC
I have connected Nokia 1 TA-1066 phone to windows PC via USB cable after enabling USB debugging in setting->System->Developer Options. on the command prompt, I am unable to get the device after executing #adb devices. Do I need any specific...
forum.xda-developers.com
But there is no option called audio source, so I selected MIDI, also no work and platform-tool windows link is not working, so I searched google and downloaded this https://developer.android.com/studio/releases/platform-tools, and it didn't work either.
All after this, something came to my mind.
Does Nokia 5 needs an unlocked bootloader to do the downgrading process?
Otherwise, Is there another way to do this? Like I saw on YouTube, someone is using ntool to do the process, but I don't know is it safe or not.
And what could be wrong with ADB? Why it's not detecting my phone?
Thanks
