Installed the package and it's working fine. It feels faster than Acer build for A500. No bugs so far the build seems stable.

My only problem is that my A501 is lacking a baseband and therefor I cannot get 3G connection. I know the problem comes from my tablet, not from the ROM.
That said, if someone knows how to flash a baseband and can provide one I'll be glad (Modem is a Huawei EM770W).

Guys thanks for testing!

To paugustin:
Ericsson F5521gw and Huawei EM770W very similar (2G/3G modem + GPS), but EM770W also have serial audio I/O (see datasheet for details). It's sad when something doesn't work, but you have good chance to have voice call functions on your tablet

During the debug of GPS issue was found that this issue related lack of patch 24974d5dd4dd6203fb26109eb433aee4ccdf1b9a (see Git https://github.com/shchers/afs_vendor_mbm_libmbm-gps). All who won't wait for new package, can solve GPS issue manually, by running the next commands in console:
Code:
adb root && adb wait-for-device
adb shell mount -o remount,rw -t ext4 /dev/block/mmcblk0p3 /system/
adb shell mv /system/lib/hw/gps.full_picasso.so /system/lib/hw/gps.picasso.so
GPS and 2G

shchers: voice support would be fun but I don't even know how to fix the modem :D

I'll keep on testing your work as it is very promising. I just won't have 3G for now.

I used to have sleep of death issues on Acer build but your build doesn't seem to be affected and that is great!

Ok, so here's where I am at.

I put together an install with Busy Box and SU. Posted on my site.

Here's the status. As I suspected, just as with the 500 ICS, we're going to need a modified Boot.img to get R/W permissions in the System directory. This is the same issue.

Things I've tried;
1. Replace boot.img with the patched 500 version.
Result: R/W permissions, but loss of Wifi.
2. Replaced boot.img with the patched 500 version and files from Modules
Result: R/W permissions but loss of Wifi and 3g

So, will have to see if Drellisdee has time to patch our boot.img

Also, cannot get Data/App and apk's to install. Modified installer script to accomodate, but will not install.

format("ext4", "EMMC", "/dev/block/mmcblk0p3", "0");
ui_print("> Mounting system partition");
mount("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p8", "/data");
ui_print("> Extracting system directory");
package_extract_dir("system", "/system");
package_extract_dir("data", "/data");

Busybox Su and Terminal works fine.

I read that Acer will be releasing ICS for the 501 this month.
Once that is out then perhaps it will make it easier.

Looking forward to a nice stable working ICS ROM.
It would be great if you can make the tablet work like a phone too

Actually, it works pretty good right now. Other than a few things I expected based on the 500 "leak". If you don't mind using ADB when you need R/W System, it works good. A did notice though, on HC bootloader, I would sometimes get SOD. But I changed an option in display settings. Will see how it goes.

Hopefully, one of the kernel devs will get a chance to patch it.

As with Acer ICS for the 501, well, maybe in a few months. Anybody who has been around android for a couple years, knows to not expect anything till it happens.

strangely in some sim card the 'sim lock' is activated, even though i never set them. and this cause the tablet cannot find any signal at all

so i need to change build.prop to this
Code:
keyguard.no_require_sim=false
via adb
