yes I see your point. Unfortunatly even if you have a host USB the device drivers included in ANdroid are very basic. storage, usb audio and keyboard are pretty much it without custom drivers.

USB Host on A100, 3G dongles

A full-sized USB port is not required for USB host. See USB On The Go from Wikipedia

We agree about this. All that is needed are a few kernel modules and some configuration files.

And it doesn't need one. To use a full-sized USB accessory, you can use a USB on-the-go cable. See This ebay listing

3G dongles, such as the very popular ones made by Huawei are designed to connect to a laptop, personal computer, or anything that supports USB Host mode. The dongles are not the host (computer), they are accessories that require something that can act as the host (computer).
[Acer Iconia Tab A100] DigitalMD:
Ok, well. I have the A100. GO get yourself one and try all these things. If you don't have any firsthand experience, you might want to listen to advice, but your mileage may vary. Once there are custom ROMs for the A100, some of these things will come along, but for now, can't do it.

No write access to /system

I've gone through the process as described and I do not have root access. I've been able to install both Superuser and Titanium Backup, but Busybox does not install. When I check /system/xbin, su is there, but I do not have write access to /system, which is what I think root access is supposed to give you. I've run the process via Terminal and via ADB with USB connection.

The build number for my device is Acer_A100_1.012.05_COM_GEN2 and kernel verision is 2.6.36.3 (I don't know if this universal or not).

When I repeat the three kernel commands the su located in /system/xbin is updated with a new "modified date" even though it is listed as read access only.

I am using Astro as my file explorer. ES File Explorer indicates that it does not have root access and does not show anything above the /mnt/sdcard level.

Thanks for any help,

Additional information:

I see where abliss asked Clubtech for some additional information. I got the same results as Clubtech to the commands quoted below

"GPS'n and Map'n" the A100

This is my first GPS-enabled device, and I was initially disappointed:

1. GPS seemed spotty, and took a long time to lock on - especially in town with tall buildings. It "unlocked" easily.

2. Google MAPS without NET connection does not allow me to mark a location (e.g. where I parked my car). Most other software requires online connectivity.

Here are some things that have made my wifi-only A100 much more useful outside; am quite pleased:

1. Tweak the GPS configuration:

Following this tweakage, I'm getting much quicker lock ons that remain connected longer. Initial position indications are not as accurate as before, but improve after a minute or so; I'd rather get ballpark quickly, than 10 feet radius after 10 minutes - or never. The following /etc/gps.config is for North America; there is likely a better SUPL_HOST than Google.

This is a work in progress; am playing with other improvements :

NTP_SERVER=north-america.pool.ntp.org

XTRA_SERVER_1=http://xtra2.gpsonextra.net/xtra.bin

XTRA_SERVER_2=http://xtra1.gpsonextra.net/xtra.bin

XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin

XTRA_SERVER_4=http://xtra4.gpsonextra.net/xtra.bin

DEBUG_LEVEL=0

# Intermediate position report, 1=enable, 0=disable

INTERMEDIATE_POS=0

ACCURACY_THRES=0

REPORT_POSITION_USE_SUPL_REFLOC=1

ENABLE_WIPER=1

SUPL_HOST=supl.google.com

SUPL_PORT=7276

SUPL_NO_SECURE_PORT=7276

SUPL_SECURE_PORT=7276

# C2K_HOST=c2k.pde.com or IP #C2K_PORT=1234

C2K_HOST=default

C2K_PORT=0

CURRENT_CARRIER=common

DEFAULT_AGPS_ENABLE=TRUE

DEFAULT_SSL_ENABLE=FALSE

# TRUE for "User Plane", FALSE for "Control Plane"

DEFAULT_USER_PLANE=TRUE

2. I hold the A100 "upside down". Antenna is in the bottom of the device, and both signal strength and number of satellites detected is improved across the board when held bottom up.

3. Use "GPS Test" (Android Market) to check your strength and satellite numbers. It'll tell you where the satellites are, and often you can establish/maintain/improve your signal by crossing the street.

4. Get a copy of "RMaps" (Android Market). This puppy allows caching of maps (sql databases) for offline use. So, for e.g., if I'm about to visit Boston, I'll "cruise" the city the night before online with RMaps at varying levels of detail - thereby storing the maps for use offline the next day. I'll also mark "POIs" on RMaps of places I want to visit; I'll POI my vehicle location when I park. Next day offline I'll have at least a marked map and compass; if I can get GPS I'll have location confirmation. Stop for coffee at a hotspot for any online updates.

5. Get a fast, big sdcard - it'll allow quicker loading of maps. Get a spare battery - GPS eats them.

Items 3 and 4 take some getting used to. "GPS test" becomes more useful with experience, as does "RMaps"; I try to use them every day on walks and erands about town. Practice marking your car, and using the maps, compass, and marker to get back.

thanks newb4r9o

I have been holding off buying a new cell phone for atleast 3 years, initially I was waiting for a 7" netbook.. with external USB WiFi support. Then this past 12 months watching 7" tablets from China, that have all had issues..

A100 is topnotch! add several free apps and you can multitask a large number of things in just two clicks.

Android 3.2 is pretty sweet!

Memory RAM is shown as 150MB used after bootup, and 451MB free

Still waiting for news about USB OTG connections....... anyone ????

regarding GPS tweak /etc/gps.config I have ?'s

Which app to do this or file program ?

Does this tweak affect GPS location when using GPS without NET access ?

SUPL_HOST - any others ?

What GPS hardware is in the A100 ?
[Acer Iconia Tab A100] losdelrock:
Back On Thread Track.

I am getting fed up.

Tried ADB, Terminal on device, Factory Reset, reset button etc.

GingerBreak as well.

No Root on an A100:

Kernel 2.6.36.3, Android Version 3.2 Build Number Acer_A100_1.012.05_COM_GEN2

I can issue the commands every which way under the sun, but BusyBox fails to install.

Funny thing is - even after a factory reset, SU is present in /xbin - before even attempting the rooting process.

Is this meant to be so?

Also, do you need a micro sd card in for the root to be successful?

How do I really erase an A100 apart from returning it to WallMart?

Thanks!

Adrian.
[Acer Iconia Tab A100] newb4r9o:
The X100 comes with a linux editor installed: vi.

So I go in using adb via the usb port and then use vi to edit stuff. You can also use an editor that comes with a file explorer (I like "Ghost Commander") and do it on the X100.

Both of these tools: vi and Ghost Commander, are linux-centric and may require a little study on the net. You could also use an editor on your Windows or MAC box; create the config file on your desktop; then "push" it into the X100 using adb, and replace the original file. I'd back up the original before making any changes by "pulling" a copy, or renaming it. After playing with Android you'll devise your own approach..

Yes.

And for me, that is the most important and most used GPS situation.

Some folks say this:

SUPL_HOST=supl.sonyericsson.com

SUPL_PORT=7275

This whole area is a dark art; I don't understand what helps and what is extraneous; e.g. some of these settings are likely appropriate for GPS that always has net access (e.g. cell phone)

Don't know - and that also is part of the mystery. I made the post only because that collection of tweaks has seemed to greatly improve my off-line and on-line GPS performance.

I should note that I can often improve GPS by simply rebooting; have even installed a "reboot" widget for that purpose.

HTH

---------- Post added at 09:16 AM ---------- Previous post was at 08:58 AM ----------

That seems curious. Understanding that I'm a complete newbie, I'd rename that file to something like su.virgin and install the su referenced in the instructions earlier in this thread (post 22; review post 34 if you're a linux user.)

I think the answer is a strong yes; the rooting instructions reference that card, and it is also readily read/write able.

Don't know; perhaps go to "Privacy"; "Factory data reset"

I wouldn't reset; I'd guess that after you get a card, the instructions will work fine for you.

Good luck!

Appears that some of the A100 come with different release keys I have a new A100 just received today that would not root using these commands with some su binaries. Symptoms as others have described, su is in /system/xbin, but root is not taking and SuperUser cannot be granted.

The release key is different it is HTJ85B/1312255785

!!!!!!!!!! Figured out the problem. you MUST use the proper SU binary. Make sure and download and unpack the su file from the SIGNED copy at this link. http://api.viglink.com/api/click?fo...n-signed.zip&jsonp=vglnk_jsonp_13162390573291

Has anyone done a teardown to see if the USB has the hardware for host capabilities?
[Acer Iconia Tab A100] DigitalMD:
USB host

A hardware tear down would tell you nothing. I'm sure the hardware supports USB host through the docking connector, but there is no dock yet. It may support it through the micro usb, but the Acer software does not support this. There is hope in the future now that Acer has posted the kernel source code, but it will take time for 3rd party developers to sort through that and it could be months before there is a custom ROM. Acer hasn't even fixed the problems with the current ROM (wifi fail, browser crashes, etc.) so I am not optimistic they will release any support for USB host on the micro usb.
[Acer Iconia Tab A100] proliant:

[Acer Iconia Tab A100] Diknak@gmail.com:
Well, I haven't had any problems with WiFi failing and I have only had the browser crash a couple of times. However, my biggest gripe with the firmware is with headphones. If you insert headphones before starting the Music app (and other 3rd party apps), the system doesn't disable the speakers. You have to open the app before inserting headphones.

Maybe they are waiting on ICS to be released before they devote a lot of time to it. I hope that they issue fixes before that though.

the the buyer if he wants it unrooted then he can do it himself.

you are selling it as a rooted device.

and besides what kind of a **** stain is he, some anal android poophead that is afraid if his android device is rooted he is going to get in trouble.

rooting is 100% legal, and most of the time the manufacturers do not care if its rooted. because rooting the device doesnt damage it in anyway.

i dont recall but this should revert or unroot your device also,,,,, i think.......just do a factory reset in the settings menu or via the stock recovery menu.

that will wipe out everything on the A100.

i am seriously thinking about buying one of these since my A500 jsut just too damn big and heavy to carry around every day.

but now that the HTC flyer is only $299 for the 16GB model at best buy... i dont know what to get.

sure they are different devices on the hardware level, but for surfing, emails, some games and youtube style video watching.... you wont see a single difference.

plus since HTC is releasing honeycomb also on the flyer,,, they will be even more alike.

[Acer Iconia Tab A100] vszulc:
Just wanted to add something...

The whole ADB process isn't necessary! Just download a terminal app from the market, and enter the three lines in there:

"/system/bin/cmdclient ec_micswitch '`mount -o remount,rw /system`' "

"/system/bin/cmdclient ec_micswitch '`cat /mnt/sdcard/su >/system/xbin/su`' "

"/system/bin/cmdclient ec_micswitch '`chmod 6755 /system/xbin/su`' "

That's how I rooted mine... Might save you a little trouble ;)
[Acer Iconia Tab A100] :
"/system/bin/cmdclient ec_micswitch '`mount -o remount,rw /system`' "

"/system/bin/cmdclient ec_micswitch '`cat /mnt/sdcard/su >/system/xbin/su`' "

"/system/bin/cmdclient ec_micswitch '`chmod 6755 /system/xbin/su`' "

And as soon as you got this done, you need to install Superuser.apk and busybox.

You can copy your busybox from your phone (/system/xbin/busybox) to /system/xbin/busybox (just copy-paste).

Then install Superuser from the Android Market!

And you're completely rooted :)
[Acer Iconia Tab A100] vszulc:
Exactly... Using the terminal might work for you, if you for some reason have problems with doing it through ADB like I did.

And if you're a newb, again like me, the ´ and ' characters might make you go: "WTF is this?!?!" Don't worry, they're all present on the Android keyboard, just switch to the numbers keyboard.
[Acer Iconia Tab A100] rootblock:
Can someone show me the output of the following when in adb shell please?

ls -l /system/bin/

I'm just trying to compare this root method to what may be possible on other devices. I have an Asus Transformer, and I have no such "/system/bin/cmdclient" command. From what I have found online, cmdclient is a Java class.
[Acer Iconia Tab A100] FloatingFatMan:
Is anything meant to be returned from the 3 cmdclient commands? I'm not getting anywhere unfortunately as I fail at the first one, fails to mount system as rw. :(
[Acer Iconia Tab A100] rootblock:
There would probably be no output if the command was successful.

On my non-rooted Asus Transformer, I can't remount the /system partition either. On my rooted phone I can though. The cmdclient command must have something to do with this...allowing you to run a root command without root..

I'm also trying to figure out the toolbox command. It seems to be a stripped down kind of busybox, allowing you to run unix commands, but what I want to know is why I can run something like the sleep command, but not the mount command, even though the permissions are the same on both. Anyone know where a config file for the toolbox command might be? Maybe it's limiting commands a non-super user can do.
[Acer Iconia Tab A100] jschall:
I'm still a bit of a newbie, and I have a question about the rooting method prescribed here.

I have successfully rooted my A100 following the method to the letter, with the help of Better Terminal Emulator and EStrongs Root Explorer.

I understand that the cmdclient command let me enter "root " commands without being root, which got the su file into place.

What baffles me is why the super user and busybox applications needed to be installed. From what I can see, the super user app just logs the times and applications that requested root access. As for busybox, I have no idea what it did, or does. My brief experience with root access has so far been exclusively with Root Explorer.

If I uninstall busybox and super user, will I be unable to use root access?

Thanks for any clues you can provide!
[Acer Iconia Tab A100] Euclid's Brother:
you don't necesarrily need busybox, it just adds a lot of commands that doesn't exist in toolbox. A lot of root enabled apps use it though.

You MUST have the superuser.apk install, as this app not only logs, but controls authentication for apps that request superuser access. This is what pops up the screen that asks "Allow" "Deny". without it, the su command will just timeout and you won't get supersuer access.
