Thought I would share my experience with this PITA tablet.
Just spent a few days scratching my head trying to factory reset a Lexibook Barbie MFC190BBEN model Android tablet.
It belongs to a 7 year old girl who put a password lock on it for some reason then forgot her password (much to her Mum's annoyance).
The Lexibook support site suggests going into settings and selecting factory reset.
Obviously this cannot be done as the tablet is locked so their next suggestion is to send it back for 'out of warranty' repair!
Some serious googling got me as far as recovery mode (sort of) which involves the reset button being pressed with a paperclip whilst pressing the power button and volume up at the same time whilst connected to a pc via usb.
This gets you a blank tablet screen, adb access but no fastboot and the adb is very limited and stops responding to simple commands.
It uses a Rockchip processor but most of the drivers do not give a stable connection.
After lots of trying to get stable connections so I can push a custom recovery (or get anything at all to talk to the damn tablet) I found that if you disonnect the usb cable and reset the tablet with the reset button you need to hold BOTH volume buttons then press the power button for a couple of seconds..keep holding the volume buttons and you should get the Android robot with a red exclamation mark.
From here I reconnected to the pc and adb could now see a device in recovery mode but with a serial of 0123456789ABCDEF
Still no joy with any adb commands....
Just a few reboots to blank screen again with no adb.
So I reset again and held the two volume buttons to get back to the Android with red exclamation mark again.
Some more googling found a different type of Rockchip based tablet that suggested NOW pressing the power button and volume up quickly..........
Well it turns out this tablet DOES have its own recovery!!!
No amount of googling told me this!!
So after days of messing about with drivers and button presses it turns out it is a simple task to reset from recovery.
You use the volume keys to choose from the minimal options in the recovery menu and use power to select.
Due to the amount of googling I did with no answers that worked (or even came close to an answer) I thought I would share this in the hope it would save someone else from pulling their hair out and keep their child happy!

you're legend, mate ... I've been trying to put google services and youtube on it for ages. Now it seems it can be done!
No mater how i press the buttons the android robot never appears just the normal start screen please describe the key pressing combination again
Press the reset button with a paperclip whilst you hold BOTH volume buttons then press the power button for a couple of seconds.
Keep holding the volume buttons and you should get the Android robot with a red exclamation mark.
NOW press the power button and volume up quickly..
This should get you into 'recovery'
Thank you. I ll give it a go. Do you know who makes the barbie tablet? I would like to get inttouch with them if it doesn't work.

hi guys,
i just god nexus from a second hand store. i want to hard reset it but it does't.
it is stuck in the screen where the little green guy with the triangle with an exclamation mark next to it. please help.
is there a way to load the factory rom manually?
(i know how to jailbrake and downgrade an iphone so this should not be so hard)
Hold volume down and press on once you see menu with recovery
press volume again and you will see option for clear storage - thats what you want
that is what i have done already. but why is the mobile preventing me from hard reset ?
I have been hanging around the XDA forums (as well as every other forum I could think of) and have been unable to solve my re-set problem.
I got my Nexus S about a week ago and decided to unlock it. That went well, no problem. Then I decided to root using Superboot - that did not go well. Now my phone is unresponsive, just sits on the Google name with an unlocked padlock on a black screen. I can get into fastboot mode by using the volume up and power button if I do this right after replacing the battery. I cannot seem to go anywhere else. Once I got into a menu that would let me install from sd card, but none of the options would install. I followed the following directions to see if I could do a hard reset:
Hard reset Nexus S using hardware buttons
This option is recommended if you are unable to access the options via the Android OS.
1. Turn the phone off by pressing and holding the Power button for about 2 seconds, the tapping Power off. Alternately, you can pull the and replace the battery.
2. Press and hold the Volume Down button while pressing and releasing the Power button.
3. Continue to hold the Volume Down button until you see a menu appear.
4. Now tap the Volume Down button to scroll down to the Clear Storage option.
5. Press the Power button to select Clear storage.
6. Press Volume Up to select Yes.
After a few minutes the hard reset process will be completed and you can reboot your phone to factory default settings.
I never get to the clear storage option, although I have tried data/factory reset and wipe cache. I can get to the android with the triangle and exclamation point but that will just sit for ever, and removing the battery at that point and then rebooting does not work. It just takes me back to the Google and the unlocked padlock. FWIW - my phone updated right before I unlocked it. I don't think it is bricked, but I sure can't get passed the Google name or the Triangle/android.
Thanks for any help.

I've the same problem now - did you ever resolve yours?
Here is how
Power off by removing battery
Hold vol up not down and power,
release power and you get Fastboot mode
vol down to recovery and click power
You get the screen with Android + triangle
Click up and Power again for few seconds
you will get the 'Android Sys recovery'
However if you have my problem 'error in loading the built in SDcard memory this wont help.
The only way i managed to get it to work some times although not now, is to reboot the mobile while it is connected to a PC, and load the PC at the same time.
However this time i am stuck at Google screen

any help would be greatly appreciated

There should be some 2-button combination that will bring you to a recovery screen that will allow you to do a hard reset (factory reset). Usually, it is the Power button + another button.
It could be
Power + Vol Up
Power + Vol Down
Power + Home
One of these combinations will bring you to a screen with an Android with a red X. Depending on the Power + combination, press the second button again. For example, if Power + Home (in the case of my cheap China-made tablet), I see the Android with red X, I will need to press the Home button again to get to the screen from which I can select to do a factory reset.
Just be patient - sometimes the buttons are a bit sticky and the combinations may not seem to work, but perseverance will pay off.
Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks

Good day !
Hi All,
New guy to the forum, but have been led here multiple times looking for answers. Typically I find them but I'm stuck on this one.
I have an AVIN 5.1.1 9" Navigation Headunit and I am stuck [during/after?] bootup with a screen that says
"Android is Starting"
"Optimizing App 1 of 1"
I've googled for a solution and it says I need to wipe the cache by booting into recovery, which leads me to a new problem--I don't know the combination to get into recovery. I've contacted AVIN, and they have responded, but with just solutions from this forum already--and not directly to the particular headunit.
I can't post pictures or links yet since I'm a new member but it looks like the 6.0 unit of the first hit when you google "e46 9 inch avin"
It has ONE hard button (RST) in the lower left above the MIC. If you press the RST button, the softbuttons light up. If you hold the RST button (even for a minute long) nothing happens until you let go of the RST button. It appears that pressing the RST button removes power from the unit and power is not returned until the RST button is depressed. During boot up, I can press the power button, but it appears that it just shuts off the LCD. I've tried holding the power button down, but nothing also happens.
I'm at a loss and so I'm trusting that the experts on this forum can help.
**SOLUTION FOUND**
using an external usb keyboard, I connected to one of the USB ports.
During boot up, I repeatedly pressed "alt+print screen+e" (no quotes).
It eventually got to recovery boot but there was no way for me to move/select options
I repeatedly pressed "alt+print screen+e" (no quotes) again
keyboard arrows and "enter" works
I know it sounds hokey so I'm not really sure on the details of how everything worked out so if anyone has insight, I would appreciate it.
Thanks!
The SOM says "HCT-SOFIA-3GR-(DDR3)REV2.0"
Hi guys.
I did a stupid move few weeks ago that make me pain in the ass!
I would like to perform a clean Windows 10 installation by removing all partitions including annoying hidden recovery partition.
Plus, I TURNED OFF THE XHCI FUNCTION IN BIOS!
As the result, I don't have any OS to boot, nor getting into BIOS.
With this model (I'm not sure if other similar Windows tablets are the same or not), if EFI partition is missing or USB EFI bootable disk attached, tablet won't let you enter BIOS!
For sure, you can use touchscreen to control cursor. But YOU CANNOT ENTER BIOS even you can see it on the screen (by pressing volumn up and power until power up)!
OK. I cut the crap. I tried to search every forum and called up to customer care. There is not an proper answer to let you know how to reset bios (not reset the OS).
Here is the trick:
1. Power off the tablet completely (long press power button until shut down)
2. Hold down Volumn UP+ and Power key until power up.
3. You will now have the screen with <enter setup> prompt, which you cannot click it to get into BIOS.
4. Hold down Volumn UP+ and Power key until screen off and KEEP PRESSING them, until you have the screen back on with the prompt telling you BIOS is reset and ask if you would like to reset the date and time as well.
That's it. It is that simple but nobody post it online that help others.~
Hope this help you all.
