CMP741e password recovery or factory restore

[remaker]

I got a Craig 741e (CMP741e), FCC ID AQF-RA-WN11087A with a lost password, stuck on a lock screen, forgotten pattern, no wifi connectivity.

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/firmware_update/android4.0/cmp741e_firmware4.0.rar

(install instructions: http://www.craigelectronics.com/firmware_update/android4.0/4.0install_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/firmware_update/android4.0/cmp741e_firmware4.0_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.

Thanks. My tablet has CM9 installed but this is kind of buggy and I was not able to restore it to factory settings. I used the cleaner firmware and it was able to wipe out the original firmware, and I was able to put in the original firmware back. I rooted it and put google play store in it and it seems to work better than cm9 rom in my opinion.

How did you root and add the Google Play store? RootThat ICS keeps failing on me using the USB wired connection. It cannot remount /system as RW, so all updates fail.
