[Acer A210] CM10.2 and CM11 coming soon - Android Software/Hacking General [Developers Only]

Hi all,
Some of you may know me from the Korean phones section where I was developing fixes for bricked phones, as I no longer have a bricked phone at the moment I moved on.
What I moved onto is opening the devices trees for the A210 tegra 3 based tablet from Acer.
yes I know there are already a few cm10 compiles out there for the Acer Axxx devices but the A210 seems to have only closed sources on the cm side and kernel, example kiwi++ based kernel/James ROMs, (if the kernel is public,then I stand corrected)
Anyway, moving on,
My current tree for cm10.2 is available on github and I will start posting compiled nightly builds as the project moves on. And develops.
For now my builds will include the cm kernel, based off kernel/acer/t30-common , mainly because I know little about kernel hacking and the goal was to get cm10.2/11 booting and usable.
Current status
CM10.2
1. WiFi working
2. Touch working
3. Sound fully working
4 no internal/external SD card yet
5 USB devices are working
6 display has flicker but otherwise fully working
7 cwm is working, touch to follow
8 PA-gapps / play store working
9 battery life untested yet
10 custom kernel/CPU gov's - not started yet
CM11
same as CM10.2 status
You can find my cm10.2 online on github, my cm11 tree is staying closed for now while I iron out some hectic bugs that have the potential to brick the device (so far I keep loosing touch and sound even across ROMs)
Anyway, onto the meat of it , if you want to compile yourself, pull the trees from here
https://github.com/darkspr1te
I also want to document some of the development process here too, time allowing (mods gods allowing)
Compiled builds to follow for now, enjoy the reading.

development call

I know there's got to be more people here capable of compiling a kernel than just the CyanogenMod team. Now that we're "official" a lot of 3rd party kernels that borrow from the d2 (Galaxy S III) CyanogenMod tree include everything you need to compile an alternate kernel for apexq. Here's 2 I found at random:
http://forum.xda-developers.com/showthread.php?t=2139055
http://forum.xda-developers.com/showthread.php?t=2226290
Also porting to other roms like AOKP or Paranoid Android is typically a matter of minor changes to the build files. Almost everyone uses CyanogenMod as a base or keeps up with CyanogenMod so the differences, if any, should be minimal.

Developers - Merging Your Working Device

If you are a developer, and wish to have a device merged into Omni, here is the current "temporary" process to use. There are 2 ways to do this - make your tree available on github (or a similar service), or request a new git tree be created, and submit it to gerrit.
1) Get your device working. There's plenty of help available in #omnirom on Freenode if you need assistance. An AOSP device tree is probably the best place to get started.
2) Set up your device to use the OmniROM "custom" build type, rather than full/aosp. More information will follow on this step - check device/samsung/manta or device/lge/mako for an example.
3) Make your device tree available on github or a similar git service. Please retain authorship of an original tree (if you fork it from AOSP or another custom ROM)
4) Come to #omni on Freenode, and have a chat to one of the core developers (they are listed at the top of the user list) - they will be able to help you get your device merged
Please note, in order to add a new device, we will require a maintainer on an ongoing basis for it, to ensure someone is able to investigate bugs that users report on a device. Without this, we unfortunately cannot enable nightly builds for a device.
will a cm kernel tree work for the most part with just a few changes?

yes - of course it must be 10.2 (4.3)
most likly it will work even unchanged

Along these lines, do NOT remove copyright attributions of a changed file. You may ADD copyrights to a header, but do NOT remove anything.

Most likely kernel change will be that reverting out that MDP sync point mess used by CM's AOSP+CAF frankendisplay. Can't link to it from my current location.
I have everything device sided transformed to Omni (m7ul,m7-common,and msm8960) and have exactly this problem now. Builds fine but Stucks after a few secs booting and hard reboots. Already looked into kmsg with maxwen but now we need to find what's causing it...
Reverted some stuff (MDP) kernel sided but haven't succeeded so far. Would be appreciated if u point us there when u back on a pc
noNeedForAsig
TF300T
OK here goes..
For the Asus Transformer TF300T the kernel forked from the CyanogenMod github:
https://github.com/scanno/android_kernel_asus_tf300t/tree/android-4.3
And the device tree, modified to get OmniROM to finish the build and get a bootable result:
https://github.com/scanno/android_device_asus_tf300t/tree/android-4.3
Hopefully it will be added to the OmniROM github.

we already making progress but it needs more work to be done.. at least we are now in system with working wifi, and display but modem doesent work.. something for tomorrow, and i dont want to hijack this thread too sorry if my question was in the wrong section but i thought i mention it because of the post above mine. nevermind i cann offer to maintain m7ul as already discussed with maxwen and oin IRC but a lot of work needs to be done:
here are my sources, device trees are usable but kernel needs more work as said above:

EDIT modem fixed, only BT left
@sykomaniac , look at first post and become a maintainer

Kernel specifics - unified kernel and recovery
It compiles fine using the repos listed above, but throws up a kernel assert error when flashing the Rom. Several compilers for different devices complained about it in the 'All the answers' thread. The way out of this is to flash a CM10.2 kernel immediately after the Rom flash aborts, then Omni boots up fine.
What works:
1. telephony
2. mms
3. WiFi
4. GPS
What doesn't work:
1. data
2. bluetooth turns off as soon as you turn it on
3. both sdcards are invisible from Android; all your stuff is there when you drop into recovery, though
4. Settings/Storage FC when tapped - see #3
5. Performance options also FC
6. Notification drawer cannot be pulled down
Camera cannot be tested because it shuts down as soon as you start it, saying: "No external storage available" - again, see #3

Is anyone else working on d2att/d2can (Galaxy S3 I747)? I'm not overly familiar with ROM development, but I can compile CM10.2 for this device just fine, and I'm slowly working on getting Omni to compile for it as well. If someone more experienced than I is already working on it though, I'll probably just let them do it.
If I am the only one, expect some newb-ish questions in the near future.

[WIP] [Help Needed] CyanogenMod 10.2 for Asus PadFone Infinity

Hi everyone,
I've been working on CM for the PadFone Infinity (pretty good device, only lacking a good community) for some time, and I've started to have some results now.
I've basically been using Asus' kernel sources and a custom-made device tree. I then tried to build CM and corrected every error I encountered to try to compile ROM successfully. I eventually succeded in compiling it, but it's now that I need help the most.
Why? Because I have no kernel development knowledge at all, and I really don't want this project to die.
So, let's list what does work and what doesn't:
-Recovery compiles and works just fine. I can backup, restore, flash roms, wipe, and everything that is needed.
-ROM and kernel compile without errors too.
-ROM does NOT boot at all. Getting past the Asus logo, the screen just switches off, and phone totally looks like it's shutdown. No backlight, keys are not backlighted either.
So here is what is needed to compile ROM:
-Device Tree
-Kernel sources (modified to compile without errors)
-PadFone Infinity stock ROM (if needed. Also, there are device blobs in it, so it might be useful)
-Asus untouched kernel sources
I do have the device, so if you need anything about it (hardware info, for example), feel free to ask. I'd love to help, even though I've already made some work, I've come to a point where my knowledge will be far from enough...
Thanks everyone for reading, and maybe for helping if you are interested in this project.
Contact Faux, maybe he will be interested in maintaining a Kernel base for this device.
Bumping.
If a xda recognized developer is willing to develop for this device, I'll have one sent to him.
I really want to have CM and some dev community on this device. I started a bounty to be able to have a device sent to a dev, it seems that many people also want development on it.
I'd also bump the thread. I also interested in CM on padfone, and especially after ASUS discontinued device support :-/

hi.. i'm already started make some modifications on ROM with other Brazilian DEV's for "Evertek S.A - SKMtek Genesis Tab GT7305"... we already found the source kernel from another Netbook or Development Board PC who uses the same SOC... but nothing already have been maked to kernel, we use the provided kernel from stock (Kernel 3.4.5+)... and about the ROM we already have two custom ROM's... One is Stock Modded (4.2.2) and another is KitKat Ported ROM from another Evertek Device... *Portuguese-Brazil Language Site/Forum
And we already make some modifications to this KK port...
- ROOT
- BusyBox
- Init.D support
- Build.Prop Mods
- SuperUser
- zipalign apps after boot
.. and other mods.
we already make too much on ROM but nothing about kernel... we want make a better kernel with optimizations and a better TCP/Clock Table, More Governors , More I/O Scheduler and maybe Overclock to 1600mhz to start after have a custom Kernel booting...
Now we need someone who understand about recovery's like CWM or TWRP and Kernel Compilation better than me to we can start make something awesome =D i think this can be used to another company's/Chinese tablets too, using the same SOC (WM8880) evidently... . . . (Found^^Working^^Recovery's)
i can't start testing here because if i flash this kernel using the Stock Recovery (WonderMedia Recovery tool) maybe i can possible brick my tablet... so if someone understand about CMW recovery to start would be nice =D

man... i just don't want blame anyone but... to we can do something to your tablet we need the kernel source and that don't stay open to developers... on this Chinese tablets we have some little configurations to can work with... but the custom kernel project i need to abandon for two reasons... first i don't have much time to can work to create a stable and functional custom kernel to everyone... second i don't have a kernel source compatible with tablets... what i found is from a electronics engineering Project computer Board ... and to it can fit on tablet is missing too much drivers compatibles with to can work smoothly and functional... someday if i found a new source maybe i can try comeback developer something to that =#
please continue developing this project
I use a genesis 7305 his kernel is very poorly optimized would like to make this usable tablet sorry for my bad English I use Google translator ;-;
2021... I tried to put a Chinese rom, but I brick the tablet, it only responds to fastboot, when I put the sudo command fastboot flash:raw boot uzImage.bin ramdisk.bin and plug in the charger and press power it appears a genesis screen.

yesterday i downloaded the Kernel source code from Samsung , now i just need TWRP Sources and and Create a Device Tree to built it
if you want TWRP for this phone , just comment down below (for some motivation)
Spoiler: that done too , look for the custom working kernel
Now For a The Custom Kernel
I Manage to Get A Custom Kernel Working with A lot Of Optimisations (Thanks @chrisaw and Others) on a Old OneUI (That System That Came with the Kernel) and it work well (it need some minor touches)
the Kernel Cant Work on Newer OneUI and Custom Roms (Pixel EXperience) because Of new Changes in Vendor Are not Compatible with the Kernel
A guess this Need A lot Of Working (Everytime Samsung do it their Way and Dont Care about The Correct Way)
ScreenShot of the Kernel
Spoiler: That is Done too too
now on Focusing on The Custom Rom , i download LineageOS 19.0 Source Code as i will build for 2 separate phones (Galaxy Z Flip3 'snapdragon 888' and UMIDIGI F1 Play 'Mediatek Helio P60') consecutively
this rom will be based on treble gsi patches but working only on Galaxy Z Flip3
i manage to build LineageOS 19.0 for Galaxy Z Flip3 , i will not share it now cause :
1 - it is not daily driver or usable , you can call it pre-alpha
2 - it has a lot of bugs that i saw , it could be other i didn't
3 - it is a Treble gsi just for testing purposes and does not have gapps (gapps needed to be included in the gsi not like a normal rom)
4 - i fix the fingerprint , now it is usable
5 - don't ask me about rear screen , it is perfectly not working at all (if you close the phone , the main display become black , rear screen have just samsung galaxy logo....)
6 - other things i forgot
Any Help will be appreciated
Stay Tune

I never finished it, but this may help with getting the kernel to build.
It's based on the ROG Phone 5 changes required for the isolated source.

That kernel never booted, so that would probably do more harm than good. It does, however, include the changes to make an inline kernel build outside the source. It was more an example than a template.

also the kernel does not boot on oneui , i have to fix it
the work is done (or atleast it works)
you can check it here TWRP Thread
@twistedumbrella i build the kernel it works on twrp but no luck with OneUI (even with knox and other security measurements disabled) it does panic (kernel panic) i need to do some investigation regarding this , if you want to help i will upload my kernel source code soon​
I have the US version, which is why I abandoned the kernel. I had no way to test the changes specific to Samsung, which would be OneUI.
Your best bet would be looking into the changes for an S21 / S22 because they are going to have the Samsung specific changes.

No worries. I would rather you know I don't know, if that makes sense. Sounds like you are more than capable either way.
