[ROOTED] Rooting An Acer Iconia A100

The A100 ships with acer/vg_gen2/vangogh:3.2/HTJ85B/1311401634:user/release-keys . Its copy of /system/bin/vold includes a fix for GingerBreak, so that exploit won't work.

I also tried the iconiaroot-1.3.apk but it did not work either. Logcat says 'E/CMD_SERVER( 102): cmd_server: invalid argument !'. They apparently "fixed" the bug by scanning the input command for semicolons. But you can still use backticks to inject commands!

So until sc2k releases a new iconiaroot-1.4.apk, this should work:

Steps to get root (LINUX VERSION):
0. put your favorite su binary in /mnt/sdcard/su
1. adb shell /system/bin/cmdclient ec_micswitch '\`mount -o remount,rw /system\`'
2. adb shell /system/bin/cmdclient ec_micswitch '\`cat /mnt/sdcard/su >/system/xbin/su\`'
3. adb shell /system/bin/cmdclient ec_micswitch '\`chmod 6755 /system/xbin/su\`'

Steps to get root (WINDOWS VERSION, just the same minus the backslashes):
0. put your favorite su binary in /mnt/sdcard/su
1. adb shell /system/bin/cmdclient ec_micswitch '`mount -o remount,rw /system`'
2. adb shell /system/bin/cmdclient ec_micswitch '`cat /mnt/sdcard/su >/system/xbin/su`'
3. adb shell /system/bin/cmdclient ec_micswitch '`chmod 6755 /system/xbin/su`'

Note that this just gives you a working "su". Installing SuperUser.apk or whatever frontend you like is left as an exercise to the reader.

So do you have the A100? I have been looking for some info on it. Mainly on if it comes with a GPS or not. There doesn't seem to be an official spec list anywhere.

Yes, it has GPS.
And yes, I have one. Importantly, though some spec sheets list USB charging, I have not gotten it to work yet.

Lightspeed
I can't wait until the Lightspeed ROM is made available for the A100.

Does anyone know if someone is working on that?

Here's hoping that someone ports this devices' 3.2 image/ROM to A500.

tried this. I can see the superuser app installed but root is not working.
adb shell > su yields permission denied.

What does "adb shell ls -l /system/xbin/su" say?
