    Updated - This update DOES NOT affect external devices using the HOST port - mouse, keyboard, or USB drives connected to the Host port are recognized.

    What you do lose is the ability to mount the SD card on computer after the update via the OTG port. The update maybe missing UdiskMountService.apk or other infoTM specific files that provided this functionality. Still researching this.

    An alternative method to determine the "hwver", without the need to use adb is through the use of a Terminal Emulator application.

    The Android Terminal Emulator by Jack Palevich is a VT-100 compatible terminal emulator for Android devices without the need to root. Additional information: jackpal / Android-Terminal-Emulator wiki

    After installing the application - From the shell prompt $ type "cat /proc/cmdline" without the "" and click the enter/return key in the bottom to get the "hwver".

    Once the "hwver" is determined the remaining steps of the update process can be followed.

    I know you addressed the Model number showing the same on different units in settings/About, but on the bottom it also shows the Hardware Version. Does show the same for the different units as well? I have the SYNET7LP version with HDMI (Also verified before using ADB) with the DG2.2 upgrade. Not sure if the DG2.02 version shows the hardware version or not.

    Hardware version wasn't displayed on the "About device" screen in DG2.02. Both the ""firmware_version" and "device_model" were hard coded into Settings.apk.

    Code:
    .line 61
        const-string v1, "firmware_version"
    
        const-string v2, "DG2.02"
    
        invoke-direct {p0, v1, v2}, Lcom/android/settings/DeviceInfoSettings;->setStringSummary(Ljava/lang/String;Ljava/lang/String;)V
    
        .line 66
        const-string v1, "device_model"
    
        const-string v2, "SYNET7LP"
    
        invoke-direct {p0, v1, v2}, Lcom/android/settings/DeviceInfoSettings;->setStringSummary(Ljava/lang/String;Ljava/lang/String;)V
    
    In DG2.20 they are also hard coded.
    Code:
        .line 64
        const-string v9, "firmware_version"
    
        const-string v10, "DG2.20"
    
        invoke-direct {p0, v9, v10}, Lcom/android/settings/DeviceInfoSettings;->setStringSummary(Ljava/lang/String;Ljava/lang/String;)V
    
        .line 67
        const-string v9, "device_model"
    
        const-string v10, "SYNET7LP"
    
        invoke-direct {p0, v9, v10}, Lcom/android/settings/DeviceInfoSettings;->setStringSummary(Ljava/lang/String;Ljava/lang/String;)V
    Therefore a SYTABEX7 or a Disgo 6000, once updated to DG2.20, using this method will report they are "Model number SYNET7LP".
    However, new in DG2.20, the "Hardware ID" will be programmatically "/proc/cmdline" identified and displayed.

    Since updating my music player and image gallery are not pulling media files. I have downloaded 4 different music players and none will pull my mp3s into the program. I can use my file manager and go to each mp3 and play them that way, but that is not very practical.

    Tried the factory reset and it did nothing. I used the iuw, don't remember what the msg were but it went thru saying it was installing. I beleive it said reboot but to tell the truth I think I may have put the wrong one in by mystake. I click on the wrong one but it installed but it will not boot or come on or nothing.

    Ok. so I pulled the pointercal file from my stock EX7 DG2.01 Kv 2.6.32.9 Zhouli@judy-pc #31 Hwvr 11.2..1.5

    ZumoDrive - pointercal

    zumodrive has been weird lately. if the main button to DL in the middle of the page doesn't work [eg error] try the other Dl link in the right column

    Windows 7 64-bit w/OTG = fail, Windows XP w/OTG = win

    The speed is much improved and the battery charge indicator isn't on permanent animate/charging. Seems zippier too!

    So my whole reason for undertaking this exercise was to run my company's UI (in Flash) on this low-cost tablet. No matter what browser I use, or site I visit or SWF I download... no love from Flash. The list of installed applications shows Adobe Flash Player 10.1.105.7. You cannot uninstall it. You cannot update it.

    Anyone know how to make it do something?

    sbartgis... having the same problem ....I tried Opera Mini....which I use on my Gingerbread htc G1 Dream(they said this couldnt be done!).

    I have just put 2.2 on my sylvania tab , following the great advice on this thread....It took me maybe 15 mins to accomplish.
    A huge thanks to all contribute to this thread.

    I can get youtube with flash to work fine....some other sites fail....

    My wifi drops off and only a reboot will restore....although on this thread....I read where reload drivers may fix it...Im trying that.

    Best of luck..
