Problems with Lenovo TAB 2 A7-10 after official update - Android Q&A, Help & Troubleshooting

Here is the situation. I updated tablet up to Android 5.0 using official software. It was working with no problems. Then system informed that you can update the system agai. And after second update, when system boots up, I get the error message that dongle is not responding. Press ok and get message that voice command is not responding. Press ok anf get message that system NS is not responding and so on. I cannot turn it off. After rebooting (long press on power button), I get the same.
SO I tried to make hard resset: long press for volume up, volume down and power buttons. I get to the screen with android and message No command. In all videos on youtube and in the net clearly stated that brief pressing the power button will open list where I can select factory reset. But when pressing power button nothing happens. Long press reboots the system, shot press no responce.
What to do? Any suggestions?

I put thread in wrong section. If moderator could move it to QandA section.

[Q] Unable to turn off my device properly iMiTo AM801 - Android 2.3.1

Hi,
since I have rooted my device (iMiTo AM801 running Android Gingerbread 2.3.1) I'm not anymore able to power off it properly.
After pressing for some seconds the power button and after I confirm the message asking if I want to power off the device, it never actually turns off and I need to press the reset button.
The problem is that quite often the reset button restart the device!! so I'm stucked.
PS: after I start the procedure for normal turn off (pressing the power button for some seconds, and answering the confirmation message) in the background I see a a message appearing just in the bottom toolbar of Android, but I cannot see what is says as the power off message is a modal window.
Any help, thanks in advance.
I solved this issue by installing one of the apps available on the Android market enabling to reboot the system.

Can't enter download mode on Samsung Galaxy Pro 12.2 SM-T900

Following different tutorials on how to root my device, they all begin with instructing me to enter "download mode." They all seem to say that I need to press Power+Volume Down+Home and, when the warning screen appears, press Volume Up. Well, I hold down Power+Volume Down+Home (I check a video to make extra sure I was holding down the correct buttons) and all that the device ever does is continually display the initial splash screen, the reboot again. If I let go, the device goes into "manual mode" in which it prompts to reboot, update the device or factory reset it. Am I missing something?
Sorry, I looked at a few articles and could not find a solution.

Hard to think that just a game would cause that to happen, but weirder things have happened...
I found this:
How to boot device into Safe Mode.
1. Press and hold the Volume - button and power button (while device is on).
2. When screen turns black release the power button, but remain holding the Volume - button.
Device should boot into safe mode.
If this works for you, then you should be able to boot the tablet with just the preinstalled apps available and then you should be able to uninstall the game in question and reboot normally.

*shrug* Not sure what else to tell you... Doesn't the tablet restart itself after holding the power button for however long like every other tablet out there...?

this is how my bootload looks like . (volume up+power button when the tablet is off) .
as you can see there is no format or anything :crying:
Well I'm not sure what your bootloader screen, which you have to use the opposite Volume button to get to, has to do with getting into Safe Mode, but ok...

Can you navigate to the Recovery option there? If so, your factory reset option should be there. I still think it would be able to boot into Safe Mode so you can just uninstall the offending app and not lose your data. But anyway, if those options don't work, you could try grabbing an update zip from Asus and see if applying that will get it going again.

What app did you install, by the way, so others might be warned against using it to avoid this situation...?

Typically, in stock recoveries, when you see the Android guy there's usually a button combo to get the commands for reboot, reset, update, etc to pop up. Usually this would be like hitting the Volume keys together or some combo of Volume and Power buttons. Unfortunately, there isn't that much info about this particular Asus tablet as the TF300 and TF700 that I am more familiar with, so can't tell you with absolutely certainy how to do it.

The OTA zip they supply doesn't appear to be able to installed via recovery, and they don't have a system.img for flashing. Here is my current thread on the issue.

Sorry about the OTA zip, I didn't read it closely enough for the install instructions. I don't know why you think the system is gone seeing as how the stock recovery can't wipe that partition...?

Mash volume up and down and power when in recovery.
The options are there (I know as I have the same tab) but I can't remember the combination
You can try and sideload the zip via recovery (I couldn't get ghat to work, got the same error)
Factory Reset from the Asus Manual
Backup and Reset
Back up data, Wi-fi passwords,and other Google servers using your Asus Tablet.
To do this:
1. Go to Settings>Backup and reset
2. From the Backup and reset window, you can:
Factory data reset: Erases all data on the tablet
Press both volume buttons to access recovery commands, find reboot with volume keys, press power to select. Done
Power lead out, Power down, hold volume down and power on, release power on when "In search of the incredible" screen shows, use volume button to select "Recovery Mode".
When Android with open stomach shows and "No Command" press and hold volume up and power button for 3 - 5 seconds then use volume button to scroll to wipe cache / wipe data use power until to select.
If it doesn't work try again until it does.

Can't enter recovery on Archos Platinum 50c

My brother fergot his password and therefore I need to factory reset the device using the recovery.
However, Volume up+ Power doesnt work for me, screen just goes black for a few seconds and it boots normally.
Anyone facing this issue too?
I have the Platinum 55d but...
I had trouble getting into recovery mode myself and this might help you.
Press and hold the power button and shortly thereafter press and hold the volume up button. Wait for the brand to load up and let go of the power button.
Wait for the android to show up. If it doesn't and the phone starts up normally, take out the battery and try again.
Once the android shows up hold the power button and tap the volume up button.
Same problem
I have the same problem
i start phone and try every way to get into recovery but cant get it on
did you find a fix?
me too! pls help!!
Thinking you can flash it with Sp-flashtool or http://www.mediafire.com/file/cgy6j622oq4lv7n/FACTORYDOWNLOAD_R2.9.9015.zip + driver
Offical firmware link etc. https://forum.xda-developers.com/android/help/archos-50c-platinum-archos-50cpl-twrp-2-t3594137
Btw sometimes it hard to boot into recovery so i use xposed to do that.

[Q] Lineage OS / screen unlock not working / can't get to TWRP

Old LG G5 I had previously installed Lineage on. Was in a drawer until I decided to charge it up and let one of my kids play games on it. When I input the correct screen lock pattern, it goes black, then comes back to lock screen.
I am able to hold power button to then select power off, restart, etc. From power off, I power on and get the orange triangle recommending to lock the bootloader. But no combination of power and vol-down or power and vol-up will get me to TWRP. It just rolls right back in to Lineage.
Also, from power off, if I plug in to my Linux laptop, it will power on and go to fastboot.
Feels like USB debug got turned off and/or trust somehow got revoked, but I never had this laptop connected to it so probably doesn't matter. But like I said, my unlock pattern is working. I get different response with correct pattern versus incorrect.
I'm also able to see the phone from my https://google.com/android/devicemanager page. I tried to send a secure and erase thinking it might let me start from scratch, but I only see a notification that "Device Located" and it never does anything.
And finally, lsusb -v does see the phone, but adb devices never does.
My question is any idea how to get back to TWRP to wipe and push an updated image or even put an updated TWRP?
Try this ...
It's like getting into Stock Recovery. To get into TWRP Recovery using button combination (hard reset) you'll need to hold volume down button and power button simultaneously, releasing power button (temporarily) once LG logo appears then quickly pressing and holding power button again, all the while maintaining hold on volume down button. The stock recovery message (white background) will appear requiring you to select volume up/down button to continue to reset software (see attached image). If you select yes it will appear to factory reset but will actually boot into TWRP.
Hope that helps!
