    Craig CMP741e Locked Screen

    I just bought a tablet from RiteAid and i think it was a preowned one bcuz wen i turned it on the screen was already locked with a pattern lock. I cant even get in to setup anything. Wen i went to do the reset button i could tell it had been tried and used based on the marks left around the hole. PLUS THE RESET DOESNT RESET OT DO ANYTHING. wat do i do now?

    Sent from my SCH-M828C using Android Tablet

    You might try flashing the tablet back to original firmware -- the Craig website has a link to download it now. Follow this link for download -- instructions there, too. Scroll down near bottom.
    Craig Electronics Inc.

    You'll need a microSD card, best results if the card only contains the update.img file.

    Since the tablet is locked, and you can't boot to android -- try turning on the tablet with the microSD card inserted. You might get a recovery option screen and follow the prompts to flash.

    If that doesn't work -- with microSD card still inserted and from a power off state -- try power on by holding the power button, and one of the toggle buttons at same time -- takes a few seconds. You might get a recovery screen, or the tablet will ask about installing an update. (Not sure if your toggle buttons are VOL- and VOL+ or MENU and ESC). Anyway try each toggle button with the power button -- and maybe something will happen for you.

    Good Luck!

    P.S. 'Power off' thought -- many tablets will power off by themselves after about 3-5 minutes of being 'locked'. I'm guessing they do this because they are expecting some input and don't get it. Others will 'power off' if you hold the power button a few seconds.

    The Craig does NOT support a reset mode, none of the typical combinations of power/volume buttons get you to a restore screen.

    The only supported way to restore to default is a firmware restore mode.

    http://www.craigelectronics.com/site/pdetails.php?id=414 will tell you how to get the firmware file

    http://www.craigelectronics.com/firm...irmware4.0.rar

    (install instructions: http://www.craigelectronics.com/firm...guide_741e.doc)

    HOWEVER! Some CMP741 units will end up stuck on the green Android screen with this version!

    If that happens, Craig has supplied a cleaner firmware in case that the first one fails,

    http://www.craigelectronics.com/firm....0_cleaner.rar

    The name of the core image in that RAR file is sun4i_crane_aihua_20121121, if that gives anyone clues about the system.

    Installs the same way - will reboot several times after the firmware install completes, and will fail the first time it runs ("Unfortunately, <process name> has stopped." over and over again). One more reboot will solve that issue.

    The Flashing software, PhoenixCard 3.06, is VERY buggy. If would not work with my built multi-card reader on my PC or with an add on-SD card reader on that PC. (could not even see the card). On my laptop, the built in PCI Card reader never recognized the card, but it finally burned the card using the add on card reader. Some people suggest disconnecting ALL USB peripherals before burning. Also, I found if the flash burning failed over and over, sometime a reboot caused PhoenixCard to start working again.
