Need help in removing pin in Android 4.0 - Android Q&A, Help & Troubleshooting

So I was lucky enough to score a free tablet from a promotion. It is a generic no-name brand device made from a company called "Ultralight Android Edge". It is a 7-inch tablet with ics and is locked with a password as I found out when I came home and tried to turn it on. I have tried to put in atleast 500 different pins to get it to unlock. Then I tried to enter into recovery mode but no button combinations would put me into recovery. The device wont turn on if a volume button is pressed with it and when it does turn on without any volume button press, I cannot force it to enter recovery later on. Please note that the device only has a volume rocker and a power button. After many failed attempts, I decided to use adb to boot into recovery but since it is locked, I cannot enable usb debugging and adb does not recognize any device. Finally I tried to boot the device while a usb cable was plugged in and although windows recognized it, a micro second later it would disappear.
Somebody please help me remove this password. I don't know why it was locked when I got it. Also, there is nothing in the box that specifies a password so not much to do there as well.
Thanks

Contact whoever was behind the promotion you won it at.

They are closed for Sunday and I don't know if they will be back for Monday...

(How To) Enter USB Host mode

All,
I inherited a seriously injured HTC surround, and I have decided to use it as a project phone.
Current status - Half Bricked on the bootloader + when it boots it immediately asks to be connected to restore backup. Unfortunately I have no zune backup and neither does the original owner of the device.
So I have read everything I could find on the half-brick issue and it seems that some folks are having success using the goldcard method to over write their boot loader with various HTC devices. I am will to try this but all the vids I have seen tutorials etc show that you have to put the device into enter usb host mode (blue writing on white screen)
Only problem is ....I have no idea how to do this on the Surround. I have tried every button combo on boot and cannot find it.
Someone here must know how to do this in return I will post my findings on whether or not the Goldcard trick works to repair a 1/2 brick surround.
Thanks

Hi,
Power off the device
Press and HOLD both camera and volume down buttons
Press power on button and KEEP holding both battery and volume down buttons
After boot screen will follow the usb screen
Now release battery and volume down buttons
Regards, ansar
Ok I can only get to the tricolor screen showing the 1/2 brick spl. is the the usb host mode? Because I see on some videos on youtube a white screen with blue writing that says enter usb host mode. This is what I am trying to achieve.
Or if this is the USB host mode should I just attempt to do the flash via gold card and see if I can get rid of teh 1/2 brick?
USB Host mode
To enter USB host mode turn off the phone, then press and hold VOL down + camera buttons, then press power.
But the phone will not enter USB host mode if you only see one line en the tricolor screen (this state is half bricked). For the phone to be able to enter USB host mode, the tricolor screen must have more than 1 line but the only missing part must be Serial/USB at the bottom. Check well the videos on youtube, and you will notice before entering USB host mode that the tricolor screen have more than 1 line (someone call this state small half bricked).
My phone is also half bricked (one line in the tricolor screen), the only solution I have found is to do an HTC OEM update, either by waiting for HTC to release an update (that includes a bootloader) through zune or by forcing it (for this the phone needs to be developer unlocked).
P.S. ChevronWP7 is not selling more unlocking tokens at the moment, and the $99 AppHub membership is too expensive for me.
Thanks Guys
After reading your posts I tried it out on my good surround and sure enough was dumped directly into Enter USB Host Mode screen
So now I am sitting here wondering what can I do with this thing it will not boot to anything but the screen to connect to restore backup.
Could I give anyone here anything useful about the device? Maybe disect it and post pics? Maybe someone could find these jtag posts? Or keep it for spare parts? Seems like a waste to just chuck it
Maybe you can repair it

rob243, you can try to install a new firmware, depending if the firmware is a version inferior to 2250.21.40500.502. You can use a tool called Cab Sender (http://forum.xda-developers.com/showthread.php?t=1306415) to send firmware version mondrian_2250.21.40500.502.cab (search in xda-developers), for the enter the phone to recovery mode (just press and hold CAMERA, then power, ang then release the 2 buttons).

[Q] locked asus transfomer prime

Hi,
yesterday I forgot my unlock pattern and now after too many attempts to unlock, I am getting google sign in option but when tablet was lock my tablet wifi was off so my google id is not letting me sign in,
So can anyone tell me can I start the wifi of my table in locked mode so i can login with my google account?( I tried the keypad wifi hot key buts is not working) or can I factory reset my tablet (my USB Debugging option is also off )
please help if anyone has any other idea to unlock the table.
Thanks
Guys plz help
If you don't mind factory ressetting try this (BEFORE DOING THAT CHECK IF YOU CAN COPY YOUR DATA FROM INTERNAL STORAGE TO YOUR COMPUTER USING THE USB CABLE WITH THE SCREEN LOCKED, AND DO IT. WHEN YOU WIPE PROM SETTINGS IT SAYS THAT IT ERASES PHOTOS (SO I THINK IT ERASES INTERNAL MEMORY)):
Turn off the tablet, I think you can do it from the lockscreen, if it doesn't work press the power button for a long time.
Turn on the tablet holding volume down and power until some text appears in the bootloader screen.
Then wait for the tablet to ask you to confirm what you want to do before 10 seconds (boot android or wipe data).
I don't remember if it was volumen down or volume up, anyway don't worry it appears on the screen. One of these buttons will allow you to choose what you want to do. The other will confirm what you've chosen. Remember to do this last thing in less than 10 seconds or the tablet will boot android normally.
I hope you can wipe this way without having to enter the pattern.

[Q] Need help resetting my tablet (not a novice user)

Hello everyone,
First of all, let me tell you that I am very good at android rom flashing and stuff and know these things. Now, here is my problem.
1. I have Aoson M19 tablet, which fell and the lcd screen stopped working.. The touch still work as I can see the output on HDMI by connecting it to an external screen. It lied in its box for sometime before I took it out again...
2. It had a pattern lock, which I unfortunately forgot, so after trying many times, it is stuck asking for my email/password immediately after boot (however the wifi is disabled at start so it never goes anywhere)
3. The tablet does not have a volume button, It has a button for Power, Escape, Home and Menu. I tried all combinations possible (as much as I could) to try and boot it so that it is recognized as an Rockchip 2918 device on my pc connected to it, but it does not work at all..
4. I tried using adb but it never shows it as a device when connected..
So I would like to ask the gurus as xda on how can I get my tablet back by either installing a new ROM (if I can get it to be recognized as rockchip device I can install drivers for it), or some other way to bypass the pattern lock somehow. Maybe some sdcard boot trick which I am unaware of till now..
(Note: this is indeed my device, not trying to hack into someone elses). Any help appreciated...
Maybe this will help: http://forum.gsmhosting.com/vbb/f90...pattern-problem-paswword-without-adb-1717216/
It was mentioned on the last page that Rockchip devices without Volume keys must connect the usb cable to PC and the port on tablet and press the reset button in the hole and the tab will be booted into the correct mode.
Tools: http://www.solidfiles.com/d/747bdce149/Rockchip_Batch_Tool_v1.7.rar
Firmware: http://www.szaoson.com/UploadFiles/Help/20130829102744_71726.rar ( 4.0 ICS v.1 )
My understanding is that the method for flashing Rockchip tablets is essentially the same across the board. So maybe try this guide for some general direction: http://www.arctablet.com/blog/featured/flashing-arnova-g2-rockchip-2918-rockchip-flashing-tool/
I don't know if this will work for your particular Rockchip tablet, but I also found this: http://forum.gsmhosting.com/vbb/f90...re-tool-how-use-guide-share-sonualok-1786042/
Please keep in mind that I do not have said tablet and am only going off of info I have found on the various forums that people reported success with. Also, be sure you do have the RK2918 version as there is a dual core RK3066 model with the same name floating around that I had noticed. The link provided is for a 2918 version. Good luck!
es0tericcha0s, you are a star, let me try and i will be back with the results.. I hope something will surely work..
Ok tried the reset button trick also, pressing it and holding before connecting the usb, and pressing after connecting usb, also tried the same with power button, but it always boots in android. And as usual the device keeps appearing as 'MID' in devie manager...
still stuck
Quick update
Ok quick update, I finally found the way to get it recognized differently (good or bad)
For Aoson M19, Hold the 'Home' key on tablet and then connect the usb cable to PC. However, it still refuses to install the drivers for the device..
See attached picture, still working on it...

[Q] VivaX TPC-7151 factory reset and recovery help

Hey XDA, you did informed me and help me a lot when I would search for a solution and find it on your forums. But now I had to make account in order to find solution for particular one here (I suppose this is a correct topic, please move if I'm wrong):
I forgot to change a really bad pattern password back to regular slide lock, and I didn't know the combination. After trying few times most combinations that I ha din my head, it suddenly asked me a google account in order to unlock it. Well, I know it, I type it and as soon as I press "sign in", a message flashes that it is loading something (just for a split second) and..... nothing. Still there, at same lock screen. I tried those without @gmail.com and null password but nothing worked, none of combinations. I read somewhere that other solution is wipe data or factory reset. Well, I'm okay with that, but how do I enter recovery mode or boot menu where I can access that?? I don't have USB debugging on, I'm sure of that, and my tablet isn't rooted (it was rooted before, but it went on service once for data wiping and it came back un-rooted I suppose)
I don't have hard reset button, but I do have physical back button on side of tablet that I can click, but I never use it. I tried with holding power button and volume up. When it shows me that image of opened android with red triangle warning sign. I release power button and now I'm stuck with that image on my screen, not knowing what to do! I can press power + volume up again to turn off tablet. Power + volume down activates safe mode and turns on tablet, atleast I discovered that feature...
If you know how to get pass that lock screen that asks for google account, anything how to wipe data with locked out tablet I would be very pleased to hear it (technically see it on here). My tablet is still in its case, locked out, and turned off for now.
Note: If I manage to get to pattern lock screen again somehow, that will also work for me. I'm sure I know correct pattern.

[Q] Phone is not being seen by computer when plugged in, usual solutions do not work

Hello all, thanks for helping me out.
I did a very foolish thing. I rooted my phone and deleted a few bloatware apps that were apparently very important to the phone's functionality. I did not install any recovery software like CWM, fastboot, or anything. It was a stock phone that I simply rooted to remove a few apps. When I went to restart my phone, I found out that I bricked it. Now my phone will only enter Download Mode if I hold the up+down volume buttons and plug it in, or it will get stuck on the LG logo screen and a Security Error screen. A factory reset with the volume down + power will work, but does nothing to fix it.
My immediate issue is that when I plug my phone into the computer, the phone will recognize it has been plugged into a power source (it will either go into Download Mode if I was hitting the volume up+volume down buttons, or start trying to boot up but cycle through the LG logo screen and Security Error screen) but the computer will not acknowledge that anything has been plugged in. There is nothing new listed in the Device Manager. I have read other threads and searched around on the internet. The usual solutions are not working for me:
I have tried several other cables and computers to no avail. I have also tested my current computer/cable, and it worked for data transfer with another phone (Nexus 4)
I have tried cleaning out the contacts on the phone. They were not significantly dirty.
I have tried installing the drivers from LG and even the UniversalNakedDriver
I believe that if I could get my computer to see my phone, I could flash the stock rom back and restore it to working order via LGNPST. I know it is simply a software issue, because prior to my rooting the phone it was recognized by the computer.
Does anyone have any other solutions I haven't tried? Or is this something I need to go JTAG on?
