Hi,
I ve a Lenco TAB-812 which was locked by kids, unfortunatly, the google account linked to unlock it does seems to be valid anymore.
So i ve tryed to hard reset it, with power - volume down key combo. It boot to the android reset menu, but once the menu is displayed, i can't validate the choice.
There is only three button on this tab + the power button : volume up to move cursor up in the menu, volume down to move cursor down, and the home key on the front which show or hide the menu...
I ve tryed many combo with power + another key to try to validate the selection but without success.
So i ve tryed to reflash it, but lenco didn't provide the rom ... even when requested by email
"If your tablet is locked please bring it back to your reseller and he will send it back to us. The only way to wipe the data is with a adb shell from your computer (while in recovery mode) but we do not support this and can't give you any information about this procedure.
Unfortunately there is no other rom available for this device."
Any ideas ?
thanks

Hey XDA! my friend is currently locked out of my LG MyTouch. The phone came out a little over a week ago so there's no forum dedicated to it yet, so I'm posting here.
She used a pattern lock and can't remember the Pattern nor her Gmail account or her password. With the past two Android phones I had, I would just Boot into recovery (Vol. Down & Power button), but this phone won't load into one. I also tried Vol. Up and Power. Nothing. I then tried both, but it went into the "S/W Upgrade" screen. Is there anyway to bypass this without having to send it back?
Thanks a lot for time guys! Hope you can help.
Hey daft
im locked out too, and cant find a way to do a factory reset :S did you solve your problem?if so..how!!
did a quick search for you. didnt render any answers. try existing methods for entering recovery mode.
1.volume down+power
2.volume up +power
volume up+down+power
the phone deff has to have a recovery system. once u get in there use the volume down button to highlight factory reset then push power
then highlight wipe data/cache and hit power. when finished reboot system now
hope this helps

also if you are familiar with adb you can navigate to adb then type adb reboot recovery
hello
Vabeach, thanks i've already tried all of those:S
volume up and power
volume down and power
both of them dont do a thing :S
and when i try the volume up + down + power....the phone goes into S/W upgrading... could it be that i need to do the upgrade and then itll let me do the factory reset? :s
Try this. Hold volume down and power. Keep holding until the lg logo comes up. Once that goes away release both buttons

Get adb on your comp. Navigate to adb. Type in adb devices. U will see your device with serial number. Then type adb reboot recovery. Problem solved.

finally the t-mobile page decided to tell us how....
i tried the link but it wont let me post..so ill paste it
A master reset (factory reset) restores the original factory settings and erases all user data (including settings and downloaded content) stored in the phone's internal memory. It does not erase data stored on the SIM card or memory card (if available).
Note: If the handset is locked, frozen, or unresponsive, you can perform a master reset using the hardware keys instead of the menu.
Note: Timing is critical in pressing/releasing keys.
To perform a master reset using hardware keys, follow these steps:
Back up all necessary data. See: Preparing for a master reset on Android.
Turn off the phone.
Press and hold the Volume Down and Power keys.
Wait 3 seconds and press the Back and Menu keys.
Note: If you see the LG logo before pressing the Back and Menu keys, the reset hasnt been completed and you will need to restart.
Release the Power/Lock key after you see the LG logo.
Release the remaining keys after the LG logo flashes (blinks once).
The Android Unpacking screen appears.
The phone will restart and complete the factory reset.
Note: If you unintentionally press the Volume Down, Volume Up and Power keys simultaneously, the phone will display a circle icon with two arrows and 'S/W Upgrade, Please wait while upgrading...' message. You will need to pull the battery and restart.
it worked on the first try!
happy holidays
Glad u found the answer

this isnt working for me....it just goes straight to S/W upgrade with no lg logo....help
Hi, I installed new rom ([JB] [P4--P4WIFI--P4VZW] 4.1.2 AOKP), but i didnt canceled the security of lockscreen with PIN. After install old PIN doesnt work and i dont have access to my tablet. Version of my recovery is: Team Win Recovery Project (TWRP) - 2.3.1.1.
holding power and volum down button redirect me to download menu
holding power and volume up button just reset tablet
what i must do now?
pls any ideas how to get to recovery menu?
It doesn't make sense that you wouldn't be able to access recovery on a hard reset unless you're using the wrong key combination.
Hold Power and Volume down which is right next to power, and keep holding them until you see the Galaxy tab logo. Then let go of Power ONLY and keep holding volume down. That should result in two options...recovery on the left, and download on the right. Let go of volume down as soon as you see the two icons, then press volume down once to select recovery, then volume up to select it.
Good luck!

txh, everything is now ok, i was wrong with second step after restarting ...

hi all
I got cheapest tablet MID M747 I think its chinese , my children try lot ot password which condamne tablet asking gmail account which it never exist there so need to restore it or reset it completely to unlock it.
I already had android tablet the combination was shut down of device press and hold volune + or - and press to power button, but his didnt work for this tablet I note there is a small hole behind (reset hole to press with spikes) when I press it the tablet reboot but still locked , I try to press it with power button but I cant find combination to do it
please I m asking all your suggestion of combination to enter recovery menu and wipe data i already did it with other tablet easely but I am frustrating with this one , I wont install rom because this cheapest tablet when u take a wrong rom its good for garbage.
the tablet have buttons power volume + volume - and behind reset pin hole
please please save me I will really appreciate your help
anyone answer please just want note that debugging mode is disabled so the only chance is to access in recovery mode and wipe data
there website talks about it but no info about firmware .
problem is the table is stuck with the voice login and no way to get to the keyboard to type the password to login.
and no volume button only power and menu. so i'm unable to make it to recovery to hard reset it.
to hard reset they told me hold power home until dopo screen then press power then home should reset but not working
i know there is no double posting but wow 46 view and no help i know that this table is crappy 40 dollers but dam
1- turn the tablet off
2- hold both power and home for about 10 seconds
3- when you see the dopo boot screen: release the power button but hold on to home for a few more seconds
4- when the screen flickers: release home
5- you're now in system recovery, use home to scroll down (there's no up but it loops around) and power to confirm
6- do what you need to do
cheers!

After two many pattern attempts, there is a sign in google account request to unlock the phone , I've tried all my google accounts it seems none of my accounts are synchronized .
one way to get away from this problem is reset factory - I need my data and I don't want to lose them - and another way is removing key pattern by root access. unfortunately my phone doesn't have root permission access and I started to root it using Adb and download mode.i followed some instructions that I found by googling the most nervous problem is the bootloader doesn't load (I tried to hold + volume key and power key or holding - volume key and power key or holding + and - volume keys with power , even back key with + volume key and power!! but again sign in page for unlocking pattern came! )
There is another problem too, if my bootloader is lock how can I found my product Id and other stuff that is needed .
I can see my device when I write adb devices in Cmd but I don't know usb debugging is on or off. my phone is Huawie G525-U00.

If you can boot to recovery mode with a button combination, do that and select factory data reset.

I try combination of buttons too (volume Up with power or volume down with power , ... ). I searched in Google how to enter to recovery mode for G525 huawei and hold those buttons but nothing happens.
always this comes:
the page that request username and password for signing in
