not working for my 1825ptz.
After boot I have ANDROID root@aspire1000# then turn to black screen with some hard drive accessing but nothing else. Have to reboot with Ctrl Alt Del
to add more details : the live cd works but when I install on hard disk it stops just after showing ANDROID root@aspire1000# with a black screen
hmm sounds like you did something wrong, if live cd works fine. Try installation again by following reece instructions below. You should use ext2 or ext3 file system.
After installation on SD card over Virtual Box Android starts to load durind my 1825ptz startap in GRUB either HDPI or MDPI shows screen with ANDROID word and then start blinking between black screen with text cursor at left-top and this ANDROID screen.
Do you have also problems with live-cd? And please explain your installation I do not realy understand what you have done –> you installed through Virtual Box to real SD-Card?? thats quite strange please try to install from CD or USB device.
That is exactly what I did :).
Sounds strange but after reinstalling everything works!
I was to lazy too look for second memory stick and bootin it as livecd.
So what I did is create virtual machine with your ISO as boot CD connect SD card to virtual box and install Android on SD formatting it as ext3. It was fine for previous Froyo is also works for this one.
I’ve already posted in google groups but I’ll repeat here:
Runs fast and smooth on my 1825ptz. Installed on external SD card.
It wolud be nice to have camera working and usable standby
There is a problem to set screen timeout to “never” the settings app
If device go to sleep then after waiking up (if any) almost all
aplications crash on start.
To bring it from sleep to alive is also a big quest.
So i set it to 30 minutes timeout.
WiFi is not connecting to known network automatically after loading.
But connects after WiFi turn off and again on.
Battery indicator is not working propertly for me yesterday it shows
77% for some hours without any change.
Is there a chance to get USB host?
The HDPI regime is not usable because in settings app the right part
of the screen is not visible.
Probably it have sence to remove it from bootloader or put at place
not by default.
Another question what means red blinking frame? is it replace for
Thankyou for your work!
Waiting for next releases.
Working just fine on my 1825PTZ, the general rules I have always followed which have worked best for me:
1) Use Gparted to format your chosen installation partition as EXT3 before installation.
2) During installation,
a)Choose not to format the partition
b)Make sure you allow partition to be set up as read/write
c)If you’re not using Linux and only have Windows installed, be sure to install Grub, the installer should detect Windows and ask if you want it included in Grub (Select ‘Yes’!)
3) If you decide to use an “fake” SD card, set size to 2045, my PC refused to boot on a few occassions when I left it on default 2047. (P.S. not sure if it helps but I always use a fake SD card.
4) During first boot, be very patient! It can take a loooonnnggg time.
Thanks Chris and Arobase for all your hard work!
I try again with formatting before as ext3. but still the same black screen at first boot.
You write first boot can take a long time… but is it minutes, hours, days ?
I wait approximatively 5 mnutes before considering not working.
hmm strange, because several users do successfully use my build on the Acer1825PTZ and Acer1825PT(ME : -) ) there must be an issue with your environment.
Which boot media do you use and how did you prepare it? Maybe try another one.
I make my bootable usb device with unetbootin and everytime before flashing a new iso I delete the whole content of the usb stick because I had strange effects if I had had other android isos on it before…
Do your Acer differ from the default sold ones? Do you replace some hardware…?
I burn the ISO and use an USB CD reader as usual.
The only hardware I change is hard drive (500Gb).
As it works on Live CD I don’t think the media could be the problem ?
I use a 30Gb ext3 partition
I try again with USB drive created with unetbootin.Same result OK with Live session, and black screen after android# when installed on hard disk
When I chose the wireless connection, it shows nothing, (also on other options in the setting menu)
I only used USB. should I plug in SD card to solve these problems?
which device do you use? Please give further details!
I used the usb live cd.
Many options in the setting menu do not work.
Should I install it into the harddisk or sth?
I am an android x86 rookie. I really dont know wht’s wrong with the system
BTW, I really appreciate your work! keep on!
Please specify which options do not work?
Installation will not change anything in comparison to live mode except you will be able to save something, so its not necessary to install.
Did you replace the wireless card of your notebook? Wifi should work with the 1825 series, I have tested on my own and other feedback was also positive.
Start in MDPI mode ONLY !! HDPI leads to issues with visibility of many settings
I found a solution to avoid the black screen. I installed again on hard disk but this time I choose to use install grub.
Now it’s ok, I’ve just lost my Ubuntu boot. it found only my windows session.
My first thoughts : it’s really great , some problems with wireless not always available or difficulties to connect….
The only big problem is to exit sleeping mode. The screen appears for one second and goes back again to sleep.
No possibilitty except reboot hard.
Now I tried to put again my triple OS boot (windows, ubuntu android).
I setup again grub2 within a ubuntu LiveCD repari.
I added custom entries for android with the same parameters but my problem is back again.
It boots android after text android, it puts the graphical logo android but stops here.
any idea ? compatibility with grub2 / grub ?
Mmh in general for a tripple boot setup you need to ensure that you define right parameters in your custom grub, what I provided above is only a example!!! Its possible that some parameters are different.
If you use not grub-legacy you need to keep in mind that you need to convert parameters.
If you will not use Android-x86 standalone or only with windows you should not install grub from android-setup.
But in general you say the android-x86 build made by me works on your system in live-mode and installed with android-x86 grub you must have some mistakes in your grub configuration from ubuntu. Maybe you provide you complete configuration and I will see if I have an idea.
I install again and modify grub. now it’s ok. I don’t know exactly what was wrong, perhaps too much tuning of my grub ?
All is almost perfect for my usage. I will now try to find a way to use a real partition rather than a virtual SDCARD limited to 2047.
The sleeping mode and wifi have to be enhanced but for the moment, it’s really usable .
Great job Chris
It gives me pleasure that its now working on your system.
It should be possible to mount any device to the sdcard directory, but I have never tried it.
Any plans for next update? if any…
Yes I have plans:
– removing HDPI Option –> already done but not upploaded
– integrate a new patch for enabling ethernet in honeycomb (upploaded in android-x86 newsgroup)
– improve suspend –> maybe by integrating pm-utils in android-x86
But I need to say that I am quite busy with work and studies, so except point one it could take a while….
awaiting for updates.
HDPI I’ve already removed from grub by myself.
Another interesting thing.
it appears that our 1825ptz have a real accelerometer!!!
I’ve just load an app from market which shows the readings from it
AND IT WORKS!!
Just before I was sure that there is some sensor which reacts with some 90° precision, just to show whether it in portrait of landscape position.
But it appears that it is complete!!
But it have some issue with the axis. Somehow the axis is wrong aligned, so it is not possible really to play some classical labyrinth with ball game 🙁 the ball is always rolling in a wrong direction.
Is it can be corrected?
Thank you again for the great job!
Is the market already imported in this version?
Yes ! and works good!
yes of course its a real accelerometer.
Yes the axes seems to be interchanged and yes I know how to fix it.
BUT today my hdd seems to be crashed! FUCK! I have a backup of my build configuration in webspace but my whole enviroment and much more is gone for the moment. So will take a longer timer to bring a new update 🙁
Crap. Hopefully it will work soon.
Do you have a donation PayPal ?
Positive update, after removing the hdd out of the tower and connecting it a different way I was able to read and boot my system from that hdd. Don’t know what is the problem, maybe my mainboard chipset (now using different sata port+cable)… at the moment I don’t care because I am backuping all important files to other disks as long as my hdd is running properly.
🙂 I am very happy about that! I was already thinking that project work (around 6 weekends) for one of my study projects is gone, but now its already pushed into the cloud.
Mmmh I have a PayPal account but no donation button on my page. I am very delight about the fact that it seems you are so satisfied with my work that you ask about that. I checked the PayPal pricing for a donation button and think the only one who has an advantage of that will be paypal 0,30cents per transaction + 2% of the donation is to much for some small donations. What do you think?
“0,30cents per transaction + 2%” I would say that it’s a kind of standard pricing.
They get it not for nothing, it is really easy fast and comfortable way for me and for many others, I guess.
P.S. It is also very “international” way.
Can I install it into a USB drive and boot it?
I don’t want to install it into the HDD because I have done sth wrong already and it costed me some money for recovery
But I really want to install some apps
How can I do that?
it no problem to install android-x86 on an usb-device. you could even use a sdcard.
use Usb-drive and sd card, You can use bootin on USB drive boot it as Live-cd and install Android on SD card. For me it works (a bit other way, in my case, but same idea).
thanks for your great job (and arobase )
i have installed it on a USB key on my acer 1425
it’s work good
but the wifi parameter is not saving and the french keyboard is ever in QWERTY
what do you mean with wifi parameter saving? I have installed this build on a hdd and connected one time with one time pw entry to my wifi and after reboot it connects automatically to wifi with old settings.
In term of keyboard, see below!
i did the same,but after reboot, it don’t connects alone
i must enter another time the password
Thank you!! Great build! Almost everything is working smooth…
I’m having trouble with WLAN. It finds the net but won’t connect. Disabling or restarting the device brings no effect. Anyone any idea?
Also: is there a howto change keyboard layout to qwertz?
Thanks again for your efforts!
hmm for me is WLAN working fine (as far as I tested it -scanning, connecting and surfing for some hours) what for encryption do you use? I use 11g with WPA2PSK.
In term of keyboard that is a general problem of android-x86 but I think I know a workaround. I need to try it next days/weeks, because I want to have QWERTZ too.
sometime wifi don’t connect. Just try to activate/deactive and it will be ok. I also installed another wireless manager in android market.
It’s easy to change physical keyboard layout. I find a solution and post it to the french 10825ptz hardware forum.
No problem now I can use virtual of physical keyboard with french AZERTY
For other keyboards layout diffrent from US you can use the tuto (just edit your config files)
your build works great so far except that i can’t install it to hard disk. on the install screen i choose the destination but nothing happens except that the install screen where you choose the destination appears again. Other builds – like the asus build – work great – never had problems with those. and in the past i did this a thousand times :-).
however thanks for your work!
Several users have successfully installed that iso, you must have made some mistake…? Give futher details or check beta2!
[…] general everything mentioned in the former post for beta 1 is still right, expect following changes and […]
So everybody I have released beta 2 with some changes and improvements.
I hope you like it!
I am awaiting your feedback.
Because of the suggestion of Chibis I have integrated a Pay-Pal Donation button on my page(on the right!) for everybody who really likes that stuff….
