[Android Q&A, Help & Troubleshooting] JarlSX:
do you mean the kernel source?

because that is available from their website

i am a developer, but have no experience on android os/rom building

with the numbers sold, i dont see a lot of developers (or any) doing work on this device

so right now, i guess all i can do is hound them :silly:
[Android Q&A, Help & Troubleshooting] runandhide05:
Not kernel source, I'm aware the kernel is open source, I'm referring to the device tree, and any proprietary blobs/bins/libs and so on.
[Android Q&A, Help & Troubleshooting] bveditz:
I originally purchased this as a touchscreen for my PC setup, for windows 8. Honestly, it wasn't good at this at all. Every time my pc screens would sleep, the acer would switch back to android mode so the next time I used it I would have to switch back. I'm not sure if there was a way to keep it on HDMI/windows mode, but I couldn't find one. The android part was just a added plus, since touchscreen lcd's are really pricey. Honestly, even if it had worked well, I didn't find it that useful. I almost never touched the screen of my desktop (where-as I like it a lot on my laptop), and also never had.

As per the android piece, I couldn't get the root working on the Android OS. I think the clockworkmod recovery for the viewsonic has some issues on the acer, the touch screen was off and it would never recognize the sdcard to push the su.zip files (and sideloading didnt' work). I thought about pulling off the stock recovery and making a new clockwork recovery with it, but after a few hours of screwing with it I just went the same route as everyone else and installed the viewsonic rooted system. Now my Acer boots up as a Viewsonic. Still not sure how I plan to use it... Wish it was a new OS that supported profiles, but I guess I'll find a profile app and see how that works. At least it's 4.0 and not anything earlier.

Rooted Nandroid Backups

I created clean Nandroid Backups from the Acer and ViewSonic Rooted ROM and would need someone to test them. Anyone out there willing to try? PM me. You would need to download the two ROM's (together 679MB) and restore both to see if they restore properly. Also check if the given instructions can be followed. As soon as it is all clear I will create a new Thread with the Information for everyone else.

It is just a way to switch pre Rooted Stock ROM's. Android v4.0.4 (So Acer users dont have to live with ViewSonic Branding or ViewSonic Users can try Acer Branding - Acer Ring for example)
[Android Q&A, Help & Troubleshooting] JarlSX:
that would be AWESOME!

what version of android will this be based on?
[Android Q&A, Help & Troubleshooting] okibi:
I have two I worked on:

Stock 4.0.4 tweaked for performance

AOSP 4.2.2 that is booting up and seems to be mostly working.
[Android Q&A, Help & Troubleshooting] JarlSX:

[Android Q&A, Help & Troubleshooting] okibi:
I haven't tried, honestly. I plan on playing with it a bit more soon. Unfortunately, I got sick late last week and am trying to rest it off.
[Android Q&A, Help & Troubleshooting] TenaciousB06:
Any updates? Acer started to unload refurbished ones on eBay, and I've got one arriving tomorrow!
[Android Q&A, Help & Troubleshooting] NapalmDawn:
So are these devices just giant android displays or do they actually act as a capable PC monitor?
[Android Q&A, Help & Troubleshooting] TenaciousB06:
They are both (the monitor includes a USB cable so that you can use it as a touchscreen; very handy with Windows 8).

Unfortunately, the refurbished one I bought has real issues with the touchscreen (only registers a touch half the time, often in the wrong place, can't drag, ghost presses); hopefully, the warranty service will take care of the issues.
[Android Q&A, Help & Troubleshooting] NapalmDawn:
What kind of video input ports does this thing have? From what I've seen, it's only HDMI in correct?
[Android Q&A, Help & Troubleshooting] TenaciousB06:
Yes, it only has a micro-HDMI input (and comes with a micro-HDMI to HDMI cable).
[Android Q&A, Help & Troubleshooting] hamzer11:
I could use someone's help. I am not highly technical but can usually follow guides pretty well. But for some reason I can not get and adb connection to the monitor. It keeps saying device not found. I connected via the included cable with my win 7 32 bit machine. I have used this same machine for my samsung s3 and s4, as well as motorola atrix and samsung galaxy tab 10.1. Not sure what I'm doing wrong. I installed the win 7 drivers that were posted by someone else also. No luck. Please help!

Did you enable Debug?
[Android Q&A, Help & Troubleshooting] jaylew:
Hi Swiss420......what do I need to do to get these 2 ROMS downloaded and tried out for you? I have a stock ACER DA220HQL which I landed as a result of the Emachines Settlements.....so I don't have any of my own capital invested in this device and don't mind experimenting with it. I have noticed that it does NOT pick up the 8 gig SD card that I installed and I see a recovery img for that here but like some folks....although I am a system admin at work....I am no Android genius at all and I have to rely on you and the many other people much much Android smarter than me. But I am pretty good at following instructions so that is a plus.

So if you can kindly let me test those two ROMS I would like to do that.....and if someone reading this could kindly advise me how to install or load that SD card recovery img file so my device will r ecognize the SD card I would really appreciate that tip too.
[Android Q&A, Help & Troubleshooting] hamzer11:
Hi Swiss, I do have debug enabled. I think I need the adb drivers. I saw a mention of something called universal naked driver. Maybe I should uninstall everything and start again.

Btw, it's the possibility of your 4.2 rom that has me really wanting to do this. Hopefully you can baked in the adjusted dpi. I noticed with xposed you can't adjust the lock screen dpi. I can't wait to get this device running JB. I get too many incompatible app messages in the play store right now.

Thanks

touchscreen issue

Hi guys,

I bought a refurbished one on eBay, like someone else mentioned on a previous post and I have (I hope it's not) an issue - I can't use it as a tablet display because it doesn't react to the touch. I have been using the keyboard/mouse to navigate through it... Am I possibly doing something wrong or do you guys think it's a defect?

Thanks in advance!
[Android Q&A, Help & Troubleshooting] runandhide05:
Sounds defective to me.

Under the settings>> developer options scroll down to touch, and check the box to show touch and touch location, then touch the screen if the panel recognizes the touch you will see cross y and x axis markers, if there is no responce contact seller for defective unit.

Ive noticed in the past ( with the HP touchpad and the first nexus 7 it was helpful to make a video of the (in my case dead zones) defective touch responce and upload it to youtube and refer seller/ manufacturer to the video for ease of explaining / proof of problem

We had a couple of People reporting that Problem. Could you do me a favor and reformat the SD-Card and make sure to cleanly unmount before removing from the PC. I am positive that it must be the SD Card causing this. It worked for me on two different Devices perfectly. You can follow the VSD220 instructions and try installing CWM on that but I doubt that it is any different and the instructions are a Little more complex. My Nandroid Backups are only recoverable if it recognizes the SD Card. Also Post what Partition type your SDCard has.

Ok.. I picked this up a few months back as a refrub.. however now it is out of warranty and not working.. However I have no see anyone with my problem yet, so I wonder could anyone here help.

Well one date all of a sudden it don't boot up.. when you power it up.. it say "waiting" then the screen goes into a shade of grey.. and few seconds goes to full black and then shade of grey and black.. This cycle for a few times then the whole unit just shut off.. If I plug in the usb to a computer, when it first turn on, it will say usb not recognized for about 1 second and then disappeared.. Does this thing have a recovery mode that could be triggered without a fully bootable system?

Anyway to restore this unit?

[Android Q&A, Help & Troubleshooting] cendanamg:
mine stopped working after i was prompted to update the device. now it just freezes at the acer bootlogo; would not boot to the android os; hence, no way to enable usb debugging; hence, no way to flash the vsd220 rom. its capacity to work as an hdmi monitor still works though ^^ since the monitor capabilities for this device is separate from its capacity to work as an android touchscreen.

hope someone can find a way to communicate with this device without booting to the system or booting into recovery mode. this update issue is fairly new so theres still chance for development.

Clean the SDCard and or use a different one. For this process you dont need to use the biggest one. It was always only the SDCard. Chances are the way you handle SDCards is wrong. Dont just unplug it. Make sure you dont have a Antivirus that will not let you unmount it cleanly.

I know this device didn't really catch on and this is a fairly quiet thread but was hoping someone could answer a few questions:

Did anybody do the latest update? It looks like it doesn't really offer much but I read a few posts that seem to indicate that the latest update might brick the device as far as android is concerned.

If someone applied the update and was rooted I want to be sure it doesn't spoil root.

Finally, I know a few devs, like [MENTION=539675]swiss420[/MENTION], have mentioned working on some ROM variant for our device and I was hoping to see if there was any progress.

I wish that would be the case. Unfortunately I can only offer Nandroid Backups of the Acer and the Viewsonic rooted ROM's. In order to restore them you need a working CWM running on the Display. I have not gotten around to flashing the newest update yet. I Downloaded it and would like to see if I can extract the Image somehow. But I am just playing around so dont expect a Custom ROM from me. Unfortunately that lies beyond my pay grade.

Regarding the other guy here in the Thread that mentioned he would be able to get a Custom ROM running on the device has not reported back in a while. I hope he proves me wrong but I doubt that he realy got it running. We can only hope someone with too much time on his Hands will create a Custom ROM for this device.
[Android Q&A, Help & Troubleshooting] hamzer11:
Thanks for the reply. I myself wish I could learn to create ROMs, I'm sure an existing ROM for other Acer devices can be ported with some tweaks. I was thinking isn't there a newer version of this monitor with a higher version of android on it? Maybe an image of that can be can be ported? Of course that would require root and custom recovery for the new model.

It's serving its purpose though. Using it in the main living/dining common area. Kids can look things up, I can run my security cameras and it's recording on the microsd card. I just finished wiring a win8 laptop to it also for more productivity for the kids.

Are you running a custom build.prop to get access to more apps in the play store. I had to side load the fios app using TiBu. Should be easier than that I'm thinking with the right build.prop.

Full screen Portrait mode?

We have around 14 of these devices that we plan to use as Kiosks set-up in portrait mode via a custom support bracket to hold it in place, however there was a recent Acer/Android system update that added "portrait mode" which actually just sets the screen to be in "portrait" centered when the screen is horizontal... meaning it shows up as a narrow thin display for it's wide 'horizontal/normal' default table mount... which isn't good for us.

Anyone know how to force a "full screen" version of the portait mode in the newest update? I've been unable to root the device even with an SD card installed (kept hanging on installing boot.img - as if it couldn't find anything but never timed out ever...?)

I might go back and try again but I doubt it'll work... thanks in advance if anyone has found a way to set back the "full screen" portrait mode - it was working before the updates...

I also seem to be unable to factory reset the devices :( anyone know how I can do it for the Acer DA241HL? I've tried using with ADB and was able to get into a bootloader which offered 4-5 options: bootloader, restart etc.

The only problem is that it says use the Volume Up/Down key... but there isn't one, I tried using the keys on the front but that just changed the devices' volume up and down and didn't seem to do anything until the screen turned itself off after 30 seconds. Even pressing the power button did nothing :(

Sent a mail to info_ch@acer-europe.com and got a phone call back asking what the problem was, tried to explain but I don't think the woman fully understood however she said she would forward it onto technical and they'd phone me back later...

Hopefully they can explain how I can use the bootloader as I'm able to get into the bootloader options (appears for about 5 seconds before it shuts off ?) so that I can reset/rollback the firmware to what it was when it was factory made? Doing factory reset from options doesn't remove the firmware updates :(

Or hopefully they're willing to create a fixed update for this new "portrait" mode that they've added that technically 'works' if you use the smart screen as normal but we don't. We need the full display to be used but just rotated 90 degrees (then using a custom mount to have the screen in a portrait mode up on a wall).
