I have a problem my glass and digitizer is damaged, I was able to access the device thru the "lg on screen" program, everything was fine, so I got it sold on an auction site yesterday, so I thought I would do the final and usual procedure to first encrypt the device and wipe device, however after I did encrypt the device I am no longer able to access the device thru "lg on screen" program, I am not able to login on the device since the screen does not respond to input, and usb says there is no device detected so I can't use the computer to input the password.
I did advertise that LG on screen did work when I sold the device, also, I do not feel comfortable selling a device with a "crackable" password with more advanced users to access my private data...for the more advanced users it is probably not that hard..
Is there any way I can input with the device ? I just need to write the 4 digit code so the device can login then "lg on screen" app should work again... WHat should I do ? I just want to wipe the device clean.. My hope is I can wipe the device thru usb some how.. to restore it back to factory reset..
obviously there seem to be a solution to my problem it is called "hard reset" which you only need the buttons on the back in order to do a factory reset, unfortunately the recovery menu does never load as it should..I wonder if that is because the device is encrypted ???
Solution:
hold down power + volume down untill the lg logo appears then let the buttons go and pres volume up and volume down and hold them..

Google/Asus Nexus 7, brand new yesterday.
The first thing I did was accept the OTA update to 4.1.1, and then reboot.
I spend the day setting up my apps and things, then I went to encrypt the phone. At this point, I have a 5-digit numerical PIN.
I leave it to do its stuff, and check back an hour later, and it's sitting on a screen saying "Type password to decrypt storage".
So I enter my numerical PIN, and it says its incorrect. I enter my Google account password just in case, and that's incorrect too.
So I go to do a hard-reset following some instructions on the Google Nexus help pages, but the device just hangs on the Google logo when trying to enter Recovery Mode. I gave it about 20 minutes just to be sure, and now I'm posting on here.
I've read some other guides which say it can work if you boot with a USB cable plugged in, but this just prevents me from selecting any options on the bootloader menu.
So I'm looking to do one of two things:
Work out what my encryption password is
Reset my Nexus
I have the same problem 'encryption bricked my device)
I have the same problem this morning after going off me for a password and I can not continue.
How to solve the problem?

OK I solved this and managed to reset my Nexus 7 by doing the following:
Turn the tablet off
Plug the tablet into a PC using the USB cable that came with it (NOT into the mains, and ONLY into USB2 not USB3)
Hold down vol-down, vol-up and power, until the fastboot menu appears
Use the volume down button to scroll to "Recovery Mode" and press Power to select
Wait for a minute until a red triangle Android logo appears
While holding volume-up, tap the power key to enter the recovery menu
Select factory reset, and Yes to confirm
It seems that the device needs to be plugged in via USB, but I couldn't get it working with my Kindle cable, only the one that came with my Nexus 7. So if USB being plugged in won't let you select any options on the fastboot menu, try using the stock cable.
same problem here.. any solutions avoiding factory reset ?
Due to my own actions (idiot) I deleted the recovery partition to try to regain 9gb it took from me. I would like to reformat and start again but I cannot. I have tried the following dell advice:
these are the steps to reset your tablet:
1. If your device is not turned off already, hold the power button for 10s to power it down.
2. Once it's powered down, press the power button to turn it on.
3. When the Dell logo appears (you may have to do it as soon as the screen turns on instead of wait for the logo to appear), hold the power button again to turn it off.
4. Do this process 3-4 times (they said 4, but it was only 3 for me) until you see something at the bottom saying that it's starting automatic system repair.
5. From there, you should see a menu. Choose "Troubleshoot", and the next menu should ask if you want to reset your PC along with some other options.
6. Choose reset PC, and when you get to the two options that ask "just delete files" or "fully reset PC", choose the second option. From there you should be able to follow the instructions to setup your device.
When I get to restore it asks for system files? I have tried the Dell recovery but that fails as well.
I have made a boot disk on my USB via an OTG cable which is recognised by the tablet, but it refuses to boot from this even after setting the bias to 1st boot from the USB.
Can anyone advise me of how to solve this problem and reformat and start again.
I forgot my home screen lock pattern. We used to have the option to get into our mobile phones via our Google account/Gmail in a bind like this. Now it only gives you 30 seconds before another attempt and that's it (?) I tried logging into Android Device Manager and it sends a code via SMS on my phone, but how can I see the SMS if I can't unlock my phone?! Is there any other way to get in? Perhaps with my Google account? Thx...

Hi.
Was reading your post.
Try rebooting in RECOVERY-Mode.
1-Turn phone off
2-Hold down: Power & Down Buttons
3-Press: Up, when Logo/Android shows
4- Scroll with: Pwr Up/Dwn to: RECOVERY
5-Select: Recovery, with the Pwr-Button
6-WAIT for phone to reboot into Recov-Mode;
then, click: "Wipe Cache Data". After that,
click: "Factory Reset" or similar wording.
Finally, reboot phone. You should now be
able to get into it without ANY locks!!!
Only downside is: this method WILL erase
all previous stuff. Hope you made a backup.
Let me know how you made out; and good
luck.
ı have a problem my lg g6 shut down and open again after closed again and phone started to warm up and doesent open. after phone is open but ı see a yellow screen and other words (ı cant share the photo because my first postbut ı try for add this photo) what should ı do?
Try master reset but you will loose all your data on internal storage. You can do master reset even from the error screen, just hold power + volume down button and when LG logo appear let go both buttons and quickly hold them again till you get to recovery menu, pick the factory/master reset option and on next screen select yes to confirm. Let it reset and hopefully it will fix this issue. If you have unlocked bootloader and are rooted, it is also possible you flashed something to the bootloader or deleted/corrupted something that is not fixable this way, if so download appropriate KDZ and use LGUP -OR- use LG Bridge to fix the device.
If the phone makes it to the launcher, perform Smart Doctor mem cleanup regularly from now on, alternatively use Android Assistant or SD Maid. These work with stock rom & w/o root.
Otherwise proceed as aforementioned.
Phone was dropped, black screen nothing to see. The phone however works. I can boot into recovery and even start adb sideload. When doing so, it shows up on my PC with adb devices. However, that is as far as I can go.
The device has a sim and pin lock, obviously I know both code. Is there any chance to recover data (contacts and images) from the phone. Grateful for any hint or a solid idea. There are plenty of posts on the web telling I should connect via adb and unlock the phone but when connecting in recovery mode it does not show up on adb devices or fastboot as the developer-mode was never enabled.
I did also try commercial software (i.e. dr.phone) but the phone doesn't show up their either.
I've the same problem. Did you were able to recover the data?
No, I ended up having the phone repaired in one of the repair shops. I was able to recover all data. Now I use the phone as a backup and for programming and experiments....

Has your phone screen cracked, leaving you unable to access your data? All is not lost! We'll show you various solutions on how to recover your data!
www.nextpit.com
This site shows the option to connect A40, if still Android 9.0, via usb hub to external screen and mouse and unlock. For Android >10 this doesn't work anymore
I have the same issue and neither usb-debugging on nor fastboot enabled. A40 doesn't show up in adb. So I also read when putting A40 via Power and Volume up into download/recovery mode, at least a backup of data should work.
My current idea is I have to replace display in repair shop or unlock via usb-hub + mouse.
Something I don't get right. How do you power off the A40 without screen to get safely the SIM card out? Power and volume down 7 sec, then release power off, then volume down? When I do this the A40 reboots with vibration. Power and volume up apparently reboots to recovery mode. Long pressing Power also doesn't turn off A40. Also in the A40 manual nothing is written on this
