I'm building a kernel right now, I just need help afterward. I've only built kernels for use in actual Linux desktops before, I enabled OTG support but after it's done building I have no frickin clue what to do with it.
[Nexus 7 Q&A, Help & Troubleshooting] SiqrCarnbon:
Hmmm Not so sure
[Nexus 7 Q&A, Help & Troubleshooting] DjDom:
You'll have to configure it to be flashable. Make it a zip and flash it. There's a guide somewhere for it.

[Nexus 7 Q&A, Help & Troubleshooting] AirCombat:
After downloading the A110 source code, I ran make menuconfig and added in OTG support, and then ran make. However I then realized I probably needed to specify arch="arm" in the make command. Also, would I have to run something like make defconfig arch="arm" to get the defaults for that kernel or does it work from the Acer default kernel options?

Just curious as I want to get it right before moving forward. I'll post my work here as I go.
[Nexus 7 Q&A, Help & Troubleshooting] djuroganovic:
look at the guide for nexus 7, that someone made here :

http://mehrvarz.github.io/building-nexus-7-kernel/

it should be very similar because of similar hardware on a110
[Nexus 7 Q&A, Help & Troubleshooting] AirCombat:
A110 Kernel build test

Thanks for that link, I did a bit more research and realized that (of course) the source code download from Acer included the defaults for this tablet (tegra3_a110_android_defconfig) which is cool because I was able to go through all the config options and learn a lot about the hardware in this tablet. If anyone is interested I could dump that info into a file and post it here.

So after I finally got the right cross compile toolchain, I (about ten minutes ago) built the kernel successfully for this tablet, with a few of my own options added in (very, very small changes, and nothing that should brick the tablet).

In order to get it right, I had to do the following extra steps on top of what I'm used to compiling:

export ARCH="arm"
export CROSS_COMPILE="usr/bin/arm-linux-gnueabi-"
make tegra3_a110_android_defconfig
make menuconfig
make -j16

(as I have an 8-core processor, it builds incredibly fast with the -j16)

But then a conflicting source said instead of just running make, you should run:

make clean -j16
make zImage -j16
make modules -j16

As I mentioned, the build went smoothly. Now I apparently have an ARM kernel... From what I've read, apparently the file I want is arch/arm/boot/zImage or arch/arm/boot/Image ... but those files are only 4 and 2MB respectively. In the root of my build environment, there's also a new System.map (which I know is important) and vmlinux, which is 96.2MB and from what I know about x86_64 linux kernels, is the more important file, along with initrd. However, this is my first time compiling for the ARM architecture so I'm sort of playing guesswork here. I also read to get the modules in a nice neat package you can run

make modules_install INSTALL_MOD_PATH=$TARGETDIR

where $TARGETDIR will eventually be /lib/modules/.. once put in the tablet system directories. But that command gives me an error of 'No rule for modules_install. Stop."

Anyway, all and any help is appreciated!

Would you please explain how did you get these images?
[Nexus 7 Q&A, Help & Troubleshooting] blokenfeffer:
Assuming you've already flashed my CWM image, you can just boot into recovery and dump your current ROM to SDCard via CWM, including any other changes you've made to customise things :)
[Nexus 7 Q&A, Help & Troubleshooting] vehf277:
I did not flash it, I used it to boot: flashboot boot recovery.img. But when I checked the result it is not the same as yours, your backup's structure made for using it as update.zip. And update-binary is the shell script.

Would you please explain me it? And some else. My A110 is A110-07g08u. How about yours? And last one. Is there a way to convert backup to Linux files structure?

Thank you in advance.
[Nexus 7 Q&A, Help & Troubleshooting] blokenfeffer:
Hi,

I'm not too sure what problem you're having, I'll be honest.

If you've booted CWM and dumped the image, CWM can read that image and write it back. If you're wanting to repackage that file, that's something different and there are guides for that, related to CWM. Usually, it's the other way around - you're trying to make an image for CWM, that takes some work, this way, you don't have to. That kind of answers your last question I guess, yes you can - but there would be easier ways of doing it, I'd imagine.

From all the investigation from members of this thread, it appears almost certain that there is only 1 model of the A110, with differing SKU numbers. None of the models have different hardware, they were just wrongly advertised that way. The biggest suggested difference was no Bluetooth, but nobody appears to own one and even that is an on off toggle in the code.
[Nexus 7 Q&A, Help & Troubleshooting] vehf277:
I read the whole thread, all 73 pages. So my questions are about the issues that are still uncovered over there.

You posted 3 CWM images. Would you please explain how did you get your 3 images in format they are?

I don't want to mess up my A110, I had the bad and hard-working experience with my another Andoid tablet to recover it from M6-Chip death. So in case to use or not your images would you please put the submodel of your A100?

And last one. If you know how to repack CWM images to Android files structure would you please tell me exact place to read the instructions?
[Nexus 7 Q&A, Help & Troubleshooting] blokenfeffer:
Those images are dumped from my CWM image directly to SDCard through CWM, as I said.

Understood, but the SKU numbers were discussed on page 20 onwards. Regardless, the fact that my CWM image works for you, means that you can dump images and use images. First step is to try to dump and restore your own ROM.

I know it can be done, you'll just have to search around.
[Nexus 7 Q&A, Help & Troubleshooting] SiqrCarnbon:
Something odd happened to me on this tablet?

Basically I have data on my SD thanks to directory bind but when I take my SD Out games do not work and it will keep having a reboot bug!

Anyway to fix will be great!
[Nexus 7 Q&A, Help & Troubleshooting] CapeNick:
As far as I understand it, Directory Bind moves the data from your internal storage to your SD card, then creates a link. So while it's linked, it will appear as though the data is in both the internal and the external with any file explorer, this way when your game goes looking for the data in the internal storage, it finds it. In actuality the data is only on the SD card, Directory Bind simply "mirrors" the data to the internal storage so the game will work. When you take your SD card out, Directory Bind has nothing to link to, because you removed the data source.

Long story short, if your using directory bind, your data is on your SD card, so it stands to reason that if you remove the SD card the game(s)/app(s) will cease to work, and potentially cause a reboot when you try to run them.

If you frequently swap your SD card for another, you can try having Directory Bind set up on both. Install the apps who's data you want to bind to the sd card, and set up Directory Bind, then remove the sd card, uninstall the apps, put your second sd card in, and start the process over again. I don't know how well this setup would work, you would likely run into issues somewhere down the road. There may be an easier solution, I just don't know of one.

Hope this helped.

[Nexus 7 Q&A, Help & Troubleshooting] AirCombat:
I haven't been able to do much work in the last week because the power has been out to half of my living room. I'm trying to get everything up and running again as soon as possible, but my landlord is taking his time in coming to fix the power outage. If it takes much longer I might just take the computer into my bedroom to fire it up, and I'll let everyone know if I make any progress. I did successfully build the kernel which is pretty awesome. I used all the default options, and then I added in as modules the drivers in options but I think would be needed to have the OTG work. Anyway I need some more help in order to package the new kernel and install it and test it. If anyone out there is willing to risk their beautiful Iconia Tab on my kernel for testing, I'd certainly be glad to help!

If anyone else has any information or any links that they think might help me, please post them here and I'll check them out. Seriously any and all help is much appreciated!

I appreciate all the work that has been done for this tablet, having it rooted has made all the difference. I do hope that development has not died yet however.

I understand the time and knowledge it takes to develop kernels and roms and respect those who do that tasks that I simply do not have the skill or knowledge to do myself. If an update to let me and all the other acer iconia a110 users who like me do not have the skills to develop know that this tablet has not been forgotten could be made it would be great. I'm not expecting a kernel or rom to be ready to go, but something to let us know that someone out there is working on it would make my day.

Beyond that I just want to send out a great big THANK YOU to all those who have helped to get this tablet rooted, and anyone that's even attempted to develop a kernel/rom for the iconia a110. All your efforts and work have not gone unnoticed.

10" Tablet UI for A110?

I recently tried to set the A110 into tablet UI mode by changing the ro.sf.lcd_density value from 160 to 133 in the build.prop file (which is in the system folder).

After I reboot, the tablet ui does show but the bottom bar crashes upon startup.

I changed the value back, but now im stuck with the default 7" hybrid ui.

Any thoughts on how to make the 10" tablet ui possible on the A110?

Apparently this method works on many other devices, such as Nexus 7.

It is intended for the Iconia A110, and I am not responsible for anything that happens with your device.

Good luck!
[Nexus 7 Q&A, Help & Troubleshooting] blokenfeffer:
This is one of the things I was trying to work on, but got stuck at custom build. There are changes required to java files, to get "true" UI mode working, the density alone won't cover it. Quite why you've not gone back to default after reverting though is odd.

See what Nova Launcher does to your current setup, it's a good alternative to native anyway, might just fix your problems.

[Nexus 7 Q&A, Help & Troubleshooting] bokchoi2020:
Hello there!

I'm not that sure about building cm 10.1 devices, but I think that you have to have the device already supported at cyanogenmod in order to type in the codename. For example, if it was the nexus 4, the codename would be mako; if it was the ASUS transformer it would be tf700t.

The guide you are reading is how to compile CM 10.1 from source, not how to make CM 10.1 for any device.

[Nexus 7 Q&A, Help & Troubleshooting] heX79:
OK, so the recovery does flash, but doesn't stick, most likely due to the recovery-from-boot.p (or whatever that file is called) that restores the recovery upon reboot.... Which is fine, so long as we can find a superuser package to flash, that will work. The 3.1.3 that I downloaded, said it installed fine, but upon reboot, there was no su or superuser on the device.

Also, noticed a lot of errors with the recovery as it loads. Seems to be log related.
[Nexus 7 Q&A, Help & Troubleshooting] sky007:
Look at the page which you got superuser apk, it does not contain the su. There is another apk need be flash as well.
[Nexus 7 Q&A, Help & Troubleshooting] heX79:
Actually, the first download does contain the binary and the binary script.
[Nexus 7 Q&A, Help & Troubleshooting] sky007:
Yes, you are right.

---------- Post added at 09:57 PM ---------- Previous post was at 09:27 PM ----------

As I understand, the install-recovery.sh (script that flashes the recovery-from-boot.p) only running when you are on normal boot. So boot to recovery from fastboot, at least we have a chance to flash our superuser apk. Also if we delete install-recovery.sh or overwrite with a empty file, the CWM should stick.
[Nexus 7 Q&A, Help & Troubleshooting] heX79:
Agreed, the only issue is, regardless of the recovery not sticking; i've flashed 3 different superuser zips for cwm, and none have gained root.
