[Android Software/Hacking General [Developers Only]] yobikap:
I would like to develop a new version for this tablet, only the problem that I have:

- I have less time

- If we can manage Kobo somehow that they release APX tools signature so we can unlock the bootloader, then I will be ready to develop for this tablet. I don't think Kobo is the bottleneck here, but the NDA that Kobo has with Nvidia, if we can somehow convince Nvidia aswell as Kobo that they release the tools and files the development can go fast.

I have created a petition on change.org, and I need 100 people to sign this. Hope that Kobo and or Nvidia will listen to our request!
[Android Software/Hacking General [Developers Only]] ThePanama:

Someone got bootloader unlock on Kindle Fire HD 7 - 3rd generation (2013). Would it be possible for Kobo Arc as well and possibly Cyanogenmod? Both have same CPU, RAM, and screen resolution. Even Nook HD has the same CPU and they have Cyanogenmod 11.

Great! Thank you so much!

my kobo arc 7hd was in bootloop after some bad mods I performed in build.prop.

The update.zip saved the device!

my set-up after the update.zip:

-rooted with kingroot

-then installed es file-explorer (with root-browser)

-then installed apex-launcher

-then installed ccleaner to disable both system- and installed apps (bloatware)

-used kingroot to disable most auto-start-apps

-placed host-file in /system/etc (extract host-file from flashable .zip from 'xda moab', google), set permissions right: no more ads

-copy original build.prop to build.bkp (in /system) then modified build.prop for faster scrolling and disable scroll-cache:

#add these lines in build.prop

#these are tested on my device and safe

#

windowsmgr.max_events_per_sec=90

ro.max.fling_velocity=12000

ro.min.fling_veloxity=10

persist.sys.scrollingcache=3

debug.sf.hw=1

#

#finish

-tap 7 times on build-number (in settings, about Kobo Arc 7hd) to enable developer options

-turn all animations off in developer options, and in Apex-launcher settings

That's about it!

Given the circumstances of the stock 4.2.2 Android I'm quite satisfied with the results. Hope it helps [emoji4]

Update: Compiling Cyanogenmod 12.1 from sources for the Kobo Arc 10HD

Hey guys, I finally have access to this section of the forums. Check out my first post here for the TWRP recovery for the Kobo Arc 10HD Only and basic information;

http://xdaforums.com/showpost.php?p=67005143&postcount=79

Details:

So far the device tree is basically complete, and I've managed to compile both the stock recovery, TWRP recovery and system image.

I've gotten the system to boot, and the screen works, but there are a lot of Tegra related issues that I am trying to solve.

If I can get them solved we might have a working Cyanogenmod for the Kobo Arc 10HD, and with the current device tree we might be able to extend it to the other Arcs.

Once I get everything to work, I will link you to the Github repositories.

Update: Cyanogenmod Currently Running [Kobo Arc 10HD]

Hey everyone, I got cyanogenmod running running barely now. Audio, Bluetooth and Wifi does not work. With my linux background I'm trying to determine how the android system initializes those modules.

Over the next few days I will start bringing the sources up online and start posting system images to flash for those who want to test it out.

The kernel sources are now available;

https://github.com/tdro/android_kernel_kobo_macallan

Without the famed "APX mode" there are a few caveats to reducing the chances of bricking your device to a minimum. I'll write about that later.

Right now I am currently recompiling the system image because I forgot to include the navigation bar, at the same time I will try to get the audio, bluetooth and wifi going.

Update: First Cyanogenmod Image Available [Kobo Arc 10HD]

These tablets are easy to brick. I am not responsible for bricked devices.

Hello, the first image is now available for download.

All new uploaded images will be available in the link below;

[URL="https://goo.gl/SHBDBS"]https://goo.gl/SHBDBS[/URL]

The camera, wifi, and sound are effectively working.

Bluetooth is not working!

There are some artifacts on boot due to the refresh rate, but it should take about 1 minute to finish on first flash. Test the image only if you know how to use the fastboot protocol, if you don't know what that is, then STOP.

I have not done any extensive testing, so things may just start randomly breaking!

This is for the

Kobo Arc 10HD

only!

Procedure

Unzip the downloaded file and you'll see the following;

system.img
recovery.img
boot.img

Boot the recovery image first to make sure it works. You should still have the default system installed, just in case you somehow lose recovery. It takes 20 seconds or so to boot.

fastboot boot recovery.img

Flash it if it boots, and CHECK that you can access it with the power and volume down buttons.

fastboot flash recovery recovery.img

Boot into recovery and BACKUP your current data. Pull the backup onto your computer just in case.

Now hit WIPE and slide to factory reset.

Reboot to the bootloader.

Flash System and Boot.

fastboot flash boot boot.img
fastboot flash system system.img

Now continue to boot the OS.

That depends on if I can get my hands on that device to try my hand at compiling, or someone else can adapt the 10HD's device tree to the 7 and compile.

When you will get kobo arc 7 for try it out?
[Android Software/Hacking General [Developers Only]] Teleferic:
I don't plan on getting that device, so I will not be compiling cyanogenmod for it. I've posted the device tree for the Kobo Arc 10HD and it is probably very similar to the other two tablets. Others who have that version might want to try and compile. They would have an easier time with this device tree as a reference;

Side Note

It seems that development is pretty much dead for these tablets, and I've notice that there isn't much interest anymore by the amount of downloads. I'll be subscribed to this thread, and continue to fix bugs that I come across but refer to the github for more information, as I will not be commenting much anymore. I'll also be checking out whether we can obtain apx mode in some way. Selinux is currently disabled for convenience.

Some update fixes require that you flash both the kernel and system image so make sure to;

fastboot flash system system.img
[Android Software/Hacking General [Developers Only]] hipocrazy:
will bluetooth be fixable? Also, can you specify if this mod is ready for daily use and if any improvements (lag etc) are noticeable?

thanks for your hard work?
[Android Software/Hacking General [Developers Only]] Teleferic:
Hi, the bluetooth is currently fixed in the latest build (12.1-20160607-UNOFFICIAL-macallan.zip). I've only tested a bluetooth keyboard though, so other bluetooth devices might have problems. Also I didn't check to see if there are bluetooth disconnection issues like in version 4.2.2.

I've also been using it as a daily driver and the only problems I found is some animation lag (recents menu) and screen tearing (graphics refresh rate?). I might have to fiddle with the graphic drivers to fix that.

I did not test the HDMI port, since I don't have a cable for it, so I don't know if it works.

Had some issues installing gapps, but a few reboots got everying up and running, I tested out xposed framework too and it works nicely. Youtube and other graphical applications work nice.

The front camera works too.
[Android Software/Hacking General [Developers Only]] hipocrazy:
great, thanks. interested but might wait until the graphic issues are sorted. Or saturday. whichever comes first :p
[Android Software/Hacking General [Developers Only]] GenghisKhan67:
This is excellent news. I'll be testing this over the weekend. Thanks again!
[Android Software/Hacking General [Developers Only]] GenghisKhan67:
I'm unable to boot the recovery image to test this. The tablet doesn't do anything after typing in "fastboot boot recovery.img". I have a "waiting for any device" prompt. I am rooted, USB debugging is enabled, "adb devices" command tells me there is a device attached (K110A39505963), su at the adb shell displays that I have admin access on the tablet, I can reboot the tablet with "adb reboot" without any problems. Any clue on what is going on? Thanks for your help.

EDIT: I managed to get to the bootloader interface via Quick Reboot app. I get a device displayed on my PC's screen when I type in "fastboot devices", so I know my USB drivers are installed properly. I tried booting to your recovery from there, but am getting a FAILED (command write failed (Unknown error)) message.

EDIT #2: OK, after a couple of reboots, I finally managed to boot to TWRP and am now backing up everything before moving forward. I'll keep updating this post with my progress...

EDIT #3: success!

Do you accept donations, Teleferic? ;)
[Android Software/Hacking General [Developers Only]] Teleferic:
Glad to see you got it working!

It might be a bit rough around the edges but it works alright so far. I'll be fixing a few other issues I came accross in the coming days.

[Android Software/Hacking General [Developers Only]] jfp555:
Incredible work dude. This is a pretty great tablet ruined by Kobo's desertion. All it needed to be amazing was a working CM which you have done. Can't thank you enough. I was out of the loop for some time and decided to check back in to see maybe there was some ray of hope.

If anyone could check out how Moonlight Nvidia streaming works (alongwith 5ghz wifi) on this I would be very thankful. I did make a post that it ran perfectly on stock kobo firmware a while back.
[Android Software/Hacking General [Developers Only]] Teleferic:
Yup those ota zip updates are in the works. For now we'll be clean/dirty flashing from the bootloader/fastboot commands, until I understand what the scripts in those generated zips are doing. Thanks again!

Also you might want to flash the new kernel, as it has some fixes to make it more compatable with cyanogenmod. There's a recovery flashable zip from the download area; Kobo Arc 10HD Downloads

Much appreciated! Kobo really slacked off with these tablets, they perform so well. Got fed up and decided to take a week and try my hand at porting. It would be amazing if we can get APX mode access, that would really speed development up. Don't want people bricking their devices permanently, lol.

Side Note

Bugs/Issues Encountered

Smart cover feature not fully working (i.e will not turn off screen when covered, this is fixable)

Notification lights control wonky (looking for open source alternative, currently disabled)

Very very rarely the system can freeze? (might be fixed with latest kernel)

Recent menu artefacts (has something to do with how the system makes thumbnail snapshots of the recent apps)

Google Play Store (might say some apps are incompatible when in fact they are not, don't know what causes this yet)

Miscellaneous battery usage calculations might be off, but it does not affect battery life.

Other To do

Configure and enable Selinux (Secure Linux)

[Android Software/Hacking General [Developers Only]] hipocrazy:
So, is this Rom faster overall? I'm very curious to try but I dont want to wipe everything just for a trial. Not trying to be downer, I really appreciate the effort put into this!

Also what version of Android is this CM Rom?
[Android Software/Hacking General [Developers Only]] Teleferic:
I can't say for sure if everything is faster or not, but I'll leave that for those who are currently testing it.

You can always backup with the custom recovery. It's like taking a snapshot of your current system (your applications + system + boot). Put that backup in a safe location and you can always go back to the stock system anytime you want. It'll be as though you never flashed anything at all.

To develop this I've been moving constantly between kobo stock rom and cyanogenmod rom, with all of my apps and data intact. Whenever I want to go back to all of my books I flash the original kobo stock rom I had, through twrp recovery.

But I won't advise flashing it if you're waiting for it to be stable for complete use. I'll be busy for a few days so updates might come a little slower.

This is Android version 5.1.1 Lollipop

download area

Kobo Arc 10HD

Kobo Arc 10HD Downloads

current revision: cm-12.1-20160624-UNOFFICIAL-macallan

important notes

Any and all updates to the rom from this point onward have to be flashed through TWRP recovery, and not fastboot!

Those who may be flashing for the first time have to flash the custom recovery first before flashing any zip. You can get to fastboot through android apps, or the adb command, you can also follow dazza9075's guide to flashing a recovery. Make sure the recovery is working, because if the boot gets borked and the recovery gets borked, then you're bricked.

the computer command;

fastboot boot cm-kobo-10hd-twrp-3.0.2-0-r1.img

lets you test any bootable image without flashing, this is very useful.

also it is a must if you are coming from stock kobo that you factory reset, so backup your stock rom.

notable system fixes

graphics fixed completely (no more artefacts in recent menu or games, better performance).

codecs streamlined for better hardware playback (up to 1440p quality youtube, etc).

device name fixed for slightly better google play compatibility (might investigate this some more later).

drm seems to be running now (netflix people will have to test to see if this is working).

opensource tegra power hal module to stabilize performance

notable kernel changes

lz4 support (relaxed boot compression, faster boot up)

network interface fixes for android 5+

cpufreq interactive controller updated for android 5+

tegra cores are running at 2.1 ghz, under stock thermal limits

bfq/fiops schedulers for those who are into those sort of things

uksm (same page merging) enable if 2gb ram is not enough
