since updating my laptop no longer reconises my tablet, I have the drivers installed. I have tried with usb debugging checked and unchecked. It jus does not show in my computer, Its so important as i cant drag my files over to the tablet.

The other problem is that, i can no longer connect to my wireless network unsecured) It does not even come up when i scan for available networks, Please help.

It would be appreciated so much.

Settings -> storage. Upper right corner is a menu. Select USB option. Then tick MTP.

Wireless is working fine here, try to do a full wipe. Backup first. Also try one of the latest nightlies of cm9.

ISI 1.2.5 to ICS, which release?

Hi All,

Is the release on this thread (last seems to be 02/05/2012) the best to get for a person wanting to upgrade from isi's 1.2.5 to a stable ICS release?

Ensure your on the latest build. Update your kernel.

Latest is 0710 (kernel).

Post a last_kmsg if you experience issue.

Ensure you don't have any apps or an unstable OC causing issue.

Camera drivers

Isi,
Is there a simpel way to add the camera drivers to this Rom? For maybe by copying them from cm9/cm10?
For me this is still the best Rom..

Or is it more complicated?


Best regards

    I am please to announce an unofficial build of Android 4.04 (CM9), Ice Cream Sandwich (ICS) for the Galaxy Tablet 10.1v (the forgotten one), GT-P7100.


    PLEASE READ ALL THE INSTRUCTIONS

    You do this at you own risk. I cannot be held responsible if you brake something.

    This is an alpha build, what does that mean?

    • It is not feature complete.
    • It will contain bugs.
    • It will not have everything working 100%, do not complain about something is not working.

    What is not working:

    • Camera
    • Tether
    • Battery usage data
    • When trying to unlock tablet the touch screen sometimes does not respond. When you press lock (power) it just dims screen. Let the tab go to sleep itself and try it again. Keep doing until it works, it does sometimes take a while to get back, or force hard reboot.
    • Screens flashes to black when you login to tab
    • If you have flashed a 7500 modem to your TAB the signal strength will not work correctly. (working on a fix, I hope)

    What is working:

    • 3g
    • Wifi
    • HQ Youtube video’s
    • Android

    Install instructions:

    • You need root
    • Backup your current tablet via CWM/Recovery
    • Copy files onto your tab.
    • You need to install a new recovery.img via fastboot , you should know how to get into bootloader to do fastboot by now, if not see instructions above for root: fastboot flash recovery /path/to/recovery.img
    • Reboot into recovery,
    • Wipe/Data reset (very important)
    • Wipe Cache
    • Flash ROM,
    • Flash GAPPS.
    • Reboot
    • Enjoy!
    • Thanks to the flowing people:

    Test ROM's available from here: http://droidbasement.com/galaxy/roms/cm9/p3/. Pershoot is providing them. They will disappear from time to time, meaning he is building new test versions. Deal with it. :D

    in reference to tether,
    im still working on the needed bits for that to properly happen (hostapd via nl80211). unfortunately as of right now, it will have to be ad-hoc/softap (wext). wireless tether should be able to do this.

    i have a newer wifi module which will be submitted for review this week. this should enhance wifi (throughput, reliability, etc.).

    New version, with 3g Tether fix.

    New Wifi driver thanks to pershoot.

    Upstream cm9/changes/enhancements.

    Enjoy.

    can you all pls test this wifi module:

    turn off wifi
    adb root
    adb remount

    download this: http://droidbasement.com/galaxy/kernels/2636/test/p4wifi/ics/bcmdhd.ko

    adb push bcmdhd.ko /system/lib/modules
    turn on wifi

    Thanks for this explanation isimobile.

    So basically we need to look for an ICS camera lib for the Tegra 2 specifically?

    So my investigation leads to the following devices that use a Tegra 250 T20 chipset:
    Acer Iconia Tab A100, A200 and A500, Asus Slider, LG Optimus Pad, Avionic Design Tamonten Processor Board, Exper EasyPad, Notion Ink Adam tablet, Olivetti OliPad 100, Point of View Mobii 10.1, ViewSonic G Tablet, Motorola Xoom, Toshiba AC100, Toshiba Folio 100, ASUS Eee Pad Transformer, Advent Vega, Hannspree Hannspad, Aigo n700, CompuLab Trim-Slice nettop, Dell Streak 7, E-Noa Interpad, Malata Tablet Zpad, MSI 10-inch (250 mm) tablet, Toradex Colibri Tegra 2, Toshiba Thrive tablet, Samsung Galaxy Tab 10.1, T-Mobile G-Slate, Lenovo IdeaPad Tablet K1, Lenovo ThinkPad Tablet, Velocity Micro Cruz Tablet L510, Dell Streak Pro, Zyrex Onepad SP1110, Zyrex Onepad SP1113G, Sony Tablet S

    => The Motorola Xoom is for example in this list and received an ICS upgrade (and more importantly, the back and front camera work on it).

    When I look at the camera specs for this device:
    BACK CAM : 5 MP
    FRONT CAM : 2 MP

    Maybe we could use this camera lib from this ROM? Maybe we could get at least the front camera to work if we're lucky.

    I've extracted this ROM for the Motorola Xoom and taken the lib's for the camera from it.
    I've then replaced the /system/lib/libcamera_client.so, /system/lib/libcameraservice.so, /system/lib/libnvmm_camera.so, /system/lib/hw/camera.goldfish.so, /system/lib/hw/camera.stingray.so with the ones from the Xoom ROM. Is this enough or do I need other files as well?

    When I start the camera it doesn't say that it can't connect to the camera anymore like previously, but the app crashes a little while later. I've attached a logcat for investigation. Someone an idea? We need a kernel modification?

    Here is how I tried to get it working, maybe it will help others as well:

    I took camera.tegra.so which I got from the Nvidia Tegra ventana official libs and pushed it to /system/lib/hw/.

    Then I pushed nvcamera.conf , a text file, to /system/etc/. This file contains the config for the camera.

    Our backcamera is a IMX073 and our front camera is s5k5bbgx. So you just need replace the values inside this file for mapping like below:

    Code:
    # format, cameraName=device,direction,orientation,type
    # type can be 'stereo' for stereo capable, 'mono' for not stereo capable,
    # 'usb' to enable searching for a usb device and where to put it in the list
    #  if found.  Lines must be shorter then 256 characters
    version=1
    camera0=/dev/imx073,back,0,mono
    #camera1=/dev/ov5650,back,0,mono   // 2nd camera for stereo once supported
    camera1=/dev/os5k5bbgx,front,0,mono
    #camera4=/dev/ov5650,back,0,stereo   // virtual stereo device once supported

    I only used the two files.

    The camera then loaded in the log.

    Then if you open the camera app it opens but FC's.

    So then I looked in logs.

    I cannot remember exactly the errors in the logs, but if I remember it was complaining about reading sensors from the camera and then it failed, that is how far I got. I then spend a couple of days trying to figure it out but then gave up.

    What I learned from all this investigation is that libcamera.so from the hc3.01, which we used on the 7500 roms to get camera working, is actually tegra.camera.so that Samsung have recompiled with their specific stuff in for IMX073 camera. Well that is my assumption in any case and one other libnv*_video.so lib, cannot remember which one, contains a reference to the camera IMX073.

    So that is why am saying, this is only my research I could be wrong, is that we need the sourcecode of the nv tegra stuff to get it working, I would be glad if I am wrong but nothing so far has pointed me in any other direction.

    If you look at all the other devices that have the tegra chip in them none of them have a working camera except for those with a leaked ICS rom. Unless it changed in the last month.

    [Edit1]
    About Kernel, the kernel has the drivers compiled in for the camera, so I do not think any kernel work is required, but again I could be wrong. ;)

    Hope all this helps.
