I got boot menu

    For rooting and uninstalling preinstalled app:
    1) Download SUT LR

    2) Download New Android Firmware for viewsonic with rooted.

    ( after downloading Extract it)

    3) Install SUT LR in XP and Connect Mobile to PC.

    4) Open SUT LR and Click Next-> Select the firmware.nb0 (options Leave "none" Next--> It will take some time Click -> Finish.

    5) It Will automatically reboot the device.

    6) Install Root Explorer (download it from

    7) Open and goto system/app

    8) click options select the app and delete.( but be careful before deleting ,if some appications are dependence ,It may crash , So Take a backup with root explorer and delete.
    9) It Worked For Me ......


    If you do so...
    you will loss original firmware...(you will not get it back any way..there is no way).
    you will not get separate ringtone for sim1 and sim2...

    Ok the other way is flash with ( some file and
    root with superoneclick...
    thats it.

    Now I have the original firmware and Root access...

    4- run SuperOneClickv2.3.3 and it should work???

    help anyone??? any ideal where I can download these

    Update 2 : looks like all I am missing is where to download


    First you need to check any updates for your software...
    Once it is updated you will have a file with .nb0 extension on your micro SD card.
    It is used as a backup or original software.
    Then you can go for ROOT your Phone.

    You can find the forum how to root and download links are in
    Startseite -
    you have to use Google translator to translate it from German to English.

    I been following what SUN-Jack did in the german forum Viewsonic V350T (Viewphone 3) firmware 5057_4_39C with and without rootaccess (no SUT necessary) - Viewsonic - and it WORKED 100% for me...

    this procedure is simple and worked 100% first time for me and finaly got my Viewsonic ViewPhone 3 V350T rooted 100%

    BTW Yes Google Translate can help on this mainly German forum, but they been very opened to responding to english post and even better they been posting often in both German and english when they know english users are tracking a thread... great bunch of guys!
    happy Camper!

    Yes Richard,

    I have tried everything from above and i seem to be getting error after error. Is it possible to root android 2.3.7. I am hoping it is something small but i am not able to get passed this and it is really driving me mad, pleasehelp!

    I really need to sort out my internal memory, it wont allow me move to sd and any app i download it requires superuser or root so you can see i needto get this sorted before i attempt to sor out my internal storage issue.



    phone details are as follows:
    Viewsonic View phone 3
    Android version 2.3.7
    Kernal version Apps_2.6.35.11-perf
    Build number 5057__39C

    Hello people,

    I know this is an old thread, but I'm trying to root my Viewphone too (just now).
    Sadly, most links are dead & the only thing I found was the firmware file by "jignesh81".
    On that one, after rebooting in recovery mode etc, I got a message that the file was eighter wrong or corrupted.
    Can someone provide me a good firmware.nb0 file? This phone is driving me crazy :/

    Hope you get to read this.

    Thx in advance!

    Ps: Android version 2.3.7 - build 5057_4_39C
