TWRP was fine before. Now touch is off, can't swipe to unlock. How to force restart? - Eee Pad Transformer Q&A, Help & Troubleshooting

This is odd. I have not changed my TWRP version (2.8.1.1) in a very long time so the problem below is not triggered by flashing a new recovery image-- or anything else for that matter. Today I went into recovery mode and:
The tablet turned on the touchpad interface (a mouse cursor appeared)
The touch screen interface is off.
The keyboard interface is off.
I tried to click on everything but although I could see a visual indication, there was no change to the chosen onscreen menu "button."
Removing tablet from keyboard dock does not help.
In desperation I held down the power button hoping to force a hardware restart. But TWRP went into lock mode.
I can't access the swipe motion to unlock.
I can't force a reboot.
I tried ADB to see if I could do a command line reboot.
Windows 10 Device Manager shows the ASUS device in the list.
Windows 10 PC can display the filesystem on the tablet.
But command "ADB devices" never shows the tablet. (Empty list.)
Weird!
Is my only choice to run the battery down?

The problem condition suddenly cleared. It's as if the tablet knew I was complaining to the XDA community.
One hour after the problem first appeared, I tried plugging the USB into the PC again. The touch screen spontaneously turned on. I was able to swipe the unlock and perform the cache clear. And performed the reboot.
You don't have to waste energy guessing what happened. But if any of you are convinced you know why this ocurred, I'd love to know so I can prevent a recurrence.
Is there a later compatible TWRP for the TF101? I couldn't find one.

[Q] Encryption broke my phone

Hi, I got Motorola Moto G, original system, no root. I just encrypted my phone, process most probably finished without problems - I stopped watching the phone on around 90%. Then it restarted, boot animation, "enter your password to decrypt the phone", I type it in, green robo shows for 1 second and then black screen (backlighted) :/ After couple hours nothing changes.
If I type wrong password, phone ofc doesn't accept it. Computer sees device, but I can't access it. When I turn off the phone by pressing POWER for long time, it just resets and goes back to asking for passwod again.
Please help me recover my data...
EDIT
before entering password PC says phone is off, after typing it, PC says it doesn't have drivers (it worked normally before encryption).
I can enter fast boot, but IDK what next. Recovery mode just ends with "NO COMMAND"
I see that probably all users who got this problem have Motorola Moto G too. Mostly people who use CM and tried to encrypt phone too.
I downloaded Android SDK, fastboot.exe tool sees my phone in this state. Not sure if it can be used to do something useful....
adb.exe doesn't see device
bump :crying:
So, I left the phone in black screen step over night. Battery ran out. I tried turning it on/off, entering fast boot mode, but nothing happened, then connected to USB. LED turned on for a while, screen too, showing battery with 0%. But now nothing again. Just black or off, not sure. Can't do literally anything, I tried pressing different keys for minutes and changing USB slot.
EDIT
nevermind, fixed battery problem, Moto G with no power needs normal charger or much longer time on USB

Dunno if this can help (and sorry for the grammar but i'm not english and i really suck at it), but for me it's normal to see "no command" on the recovery, to see the recovery commands you just need to:
(Token from Customer Help Motorola):
1. Go in fastboot mode.
2. Select the voice "Recovery".
3. Now the phone'll show motorola's logo and then the android bot with the exclamation mark.
So now, you have to press VOL UP for 10-15 seconds. while pressing it, press and release the POWER button.
U should now see the voices in the recovery.

If you can get the phone to be recognised try reflash firmware
Sent from my Moto G using XDA Free mobile app
Thanks for replies. Menu in recovery mode lets me wipe all data, so that's last thing I want to do, but I guess I will have too soon :/
About flashing firmware - from what I've read, encrypted data on phone is protected by password and some kind of encryption key/file. Reflhasing would cause permanent lose of that key and thus whole encrypted data.
The only solution I guess is copying that key on PC. Copying encrypted data if possible, and decrypting on PC using some tool, as Android is open source, so it shouldn't be a problem to extract it's decryption mechanism and run it on PC.
OR copying key to PC, reflashing phone, copying back key and praying this time system will start.
Well what's more important I working phone or a few apps??
If you need to get data off the phone maybe using a otg cable and using the file manager in recovery to copy it all over to the USB otg but as far as that I think your gunna have yo count your losses and learn not to encrypt your phone lol....

Help: Superuser causing freeze on startup?

Hi, i have a rooted Samsung galaxy prevail 2, and just recently my phone has appeared to stop working. when i reboot it, the message 'shell has been given superuser permissions' is displayed and the screen is frozen. in this state none of the hardware buttons work except the power button except it only works to reboot, not turn the screen off. the low memory icon is also displayed in the top left. i should mention that this has happened before a while ago but my phone returned to normal after three days and i did nothing to fix it. this time its on day seven of freezing on every reboot. i have tried to factory reset using the hardware buttons but once it gets to the second logo and displays the message at the top left, it doesnt continue to the recovery menu and instead shuts back off. i have also tried to connect it to my computer to look through the files but it will not accept the driver the computers trying to install. i even downloaded the correct driver from the samsung website. any help? thanks.

[HELP] Phone recognises touches but screen unresponsive (Works in safe mode)

Moto X Style not rooted
I have show touches on so I can see that the screen recognises the input but the phone won't correspond with what I'm telling it to do. Even when using a mouse via USB debugging.
Every time upon restart, it works properly for a minute or so, then the navbar & statusbar dissapear, screen fades to black and locks. When I press the power button, it shows the lock screen but won't let me press anything. Apart from the Power Off pop up when it appears. I also can still interact with the always on display.
If I boot it in safe mode, the issue doesn't occur and I can interact the screen indefinitely.
I've not installed any new apps recently but this just started happening about a day ago.
Any ideas of what's wrong/how to fix it?

If it works in safe mode but doesn't when booted normally, then your issue is caused by something that you installed yourself. Use trial and error to figure out which of your installed apps is causing the issue by uninstalling apps and seeing if this issue still happens, when you uninstall the offending app, it should start working like it is supposed to.

HELP! HTC U11+ Just won't turn on!

I've been using HTC U11 Plus as my main phone since the day it came out. I absolutely love this phone. In my opinion it's the best phone I've ever had. I never felt the need to get a new phone. I've been gaming, working, etc. and I never had any issue with it.
Two days ago all of a sudden while using my phone it got stuck. None of the button were working and the screen also had response so I pressed and hold the Power button and Volume Down button to boot into recovery mode. So i could clear cache and reboot again but my phone doesn't seem to reboot. It just turns off when I select reboot now. I even tried "Wipe data/factory reset from the Recovery menu options" and then delete all user data option and then Reboot system now to restart your phone. Still no luck. As soon as I press on reboot system my phone just turns off and doesn't reboot or turn on at all.
Even when I put my phone on charging there is not light to indicate that my phone is charging at all.
PLEASE HELP!!!!
Same problem here... Screen flashed white, phone rebooted to encryption screen to enter pin, then powered off... Hasn't been back on since (thins happened in October 2021).
I'm interested in a possible way to get the data off the phone, even if some parts swapping is involved.
PS. I changed the battery thinking it was that, but the phone still isn't coming on or showing the red battery charging light.
I guess it is time for you both to use ADB. When installed properly you should be able to see your phone in device manager on Windows systems. That in itself would be a good starting point. Or just fire up ADB and check if ADB detects your phone. If you are unfamiliar with ADB, Google it.
In ADB use: *.\adb devices* (without the *) If it works properly you should get a return with a device number. You could then flash a boot image or system image or both and see if your phone start's up again.
Hello,
same Issue here.
Solution is to heat up the Phone above 50°C and hold the temperature while it run and copy Data.
I have spend 40h+ to Backup Data and heat up the Phone.
Seems for me to the same problem like the RROD at Xbox360.

Question Stuck in recovery mode PLEASE HELP

I thought this would be a good place to ask this.
A few minutes ago, I accidently pressed the volume up and down buttons for a long time on my zflip 3 and it booted into the recovery menu. Now this normally wouldn't be a problem.. if my power button wasn't dented in.
I refused to fix it due to the sheer cost of the fix and could turn my display off by double tapping. However, this means that I have no way to exit recovery mode. I tried using ADB on both my bac and pc (using usb 2.0, 3.0, and c on my pc and c/thunderbolt ports on mac).
My phone however would not connect of show up under devices, and I am suspecting it is because I have done something to the debugging settings. I let the battery run out and it would just boot back into the recovery interface once charged up. It even once went to a light blue screen that said something along the lines of how a custom os can cause major problems.
I am a noob at phone stuff and I really don't know what to do. I have a bunch of photos of my grandma who passed away last year and they aren't backed up to google cloud. I really need any help I can get. Thank you.
Hi, provided that you have already
- enabled adb debugging;
- installed adb.
Now you have to
1. enter fastboot mode;
2. in adb type
Code:
fastboot erase recovery
then, reinstall recovery if you want to.
