Samsung A21 keeps saying that I'm using the wrong pattern.
Steps taken to try and resolve:
Samsung account, find my mobile or whatever it's called. I was able to log in and see the location of the phone but when I tried to unlock, it said that remote unlock was not turned on, on the phone.
Google account: Said "notification sent" and that was it, nothing more.
Last thing I want but would do is a factory reset. Problem is, it asks for the pattern to shut down the phone.
Was going to pull the battery to shut it down, but the back is glued on and I don't want to damage the case even slightly. It's my mothers phone. If it was mine, I'd take the chance.
I'm at a freaking loss and can't believe this bug exists to this day.
Edit: I've set it to the download mode screen (the screen stays on and will drain the battery) and will let the battery die. I think, once dead, I should be able to plug in and quickly hold the buttons and get into recovery mode and reset it. Yes no maybe?
yes you can reset the phone
but you can not save the data

Samsung Galaxy Tab 2 10.1 Hacked, Touchscreen unresponsive
Hi! I need help with my tablet.
Device: Samsung Galaxy Tab 2 10.1 Tablet, model GT-P5113 TS. This model doesn't have a way to yank out the battery.
What's wrong: Touchscreen is not responding.
Current state: Attempting to drain the battery. Doesn't appear to be turned on. Factory reset apparently performed.
What happened: Sorry, this is long. It is as best as I can remember it. It may be somewhat inaccurate.
Yesterday evening, I was on my Windows laptop and logged into my Google account. I *thought* I used the Google Play Store to install Chrome to the tablet. (I had looked at the html5test website and it said Chrome had a higher HTML5 rating than the Dolphin/Jetpack browser I've been using on my tablet.)
But something went terribly wrong.
After sending Chrome to it, I unlocked the tablet and used both Chrome and Dolphin to go to html5test website. They both scored the same or nearly the same. I don't know if any of that is relevant, but I'm including it just in case.
At some point after that, I woke the tablet with the power key and used my unlock pattern on the dots lock screen.
That's when I saw what I believe was mal-ware in action. The settings menus were scrolling and sub-menus being selected, all by themselves. I couldn't say exactly what was changed because whatever program or script that was running the process was going extremely fast.
When I realized it might be trying to send out data over my Wifi network, I turned off the Wifi router in my home.
I repeatedly held down the power key to turn the system off, but doing so only rebooted back to the useless lock screen which was not responding to anything. The normal method of holding the power button for a few seconds to bring up the menu and then tapping the "Power Off" option on that menu refused to power off the system. Nothing on that menu responded to touch.
Entering my pattern on the lock screen did absolutely nothing. I didn't even see any lines traced when I ran my finger over the screen.
At some point, I pulled out the external SD card. I have no idea if whatever hacked the tablet also put a copy of itself on the SD card.
I called a friend who looked up how to restore the tablet to factory settings. I didn't understand the directions exactly, so I ended up on a screen with a Warning!! about installing a Custom OS. (Holding down the Power + Volume Up seems to get me there)
I left it on this screen, and I turned my router back on and using my laptop, contacted Live Chat at Samsung but they didn't understand my problem. They told me to reboot the device and swipe my pattern several times and then after several failed attempts I would have the chance to use my Google credentials to get into it. But the device apparently never registered that my swipe attempts were failing.
So my device was booted up with me locked out, with the WiFi router on for a little while again. I turned off the router as soon as I realized that. That disconnected the chat session, but since Samsung chat wasn't helping me anyway, I didn't bother trying to go back.
I got the device back to the "Warning!!" screen. Then turned the router back on and searched for how to do a factory reset of the device. I found a video on YouTube and followed it.
I pressed the Volume Down and Power buttons simultaneously, followed by letting go of the power button. That brought up a menu which contained several options, including an option to do a factory reset. I used the volume buttons to highlight that and pressed Power key. A second screen came up and I used the volume buttons and power button to select "Yes" to confirm the reset.
It appeared to have done a factory reset, rebooting eventually.
However, after that, when I tried to tap on the touch screen to move forward through the selections, the touch screen was still unresponsive!
So I brought back the "Warning!!" screen and ran the battery down until the screen was blank and it wouldn't start when I held the power key.
Then I charged it for about 20 minutes and rebooted it. I think when it came back it was on the Recovery menu. I think I did a second factory reset, but not 100% sure. It eventually rebooted after a lot longer than usual.
When it came up, it was saying battery was low. I tried to tap the OK button, but nothing happened. Behind the battery window was the first setting screen to set up the device for the first time after a factory reset. (I think selecting USA?)
I brought back the "Warning!!" screen and left it on overnight so that the battery would run down.
That was about 8 hours ago. When I woke up, I used clear tape to keep the power button pressed down, to ensure that the battery will continue to run down.
____________________________________________
What do I do next? How do I get the touch screen to start working again? It is not a hardware problem, unless mal-ware can break the hardware. The touchscreen had been working fine until this happened.
Should I take the tablet back to Best Buy where I bought it at least a year (maybe 2 years) ago? I don't know if it's still under warranty.
I have over 20 year of experience as a software developer, but not for Android. I am not very experienced with doing anything to hardware.
Should I try to fix it myself?
I have never rooted any Android device and I'm not sure what that means, either.
I've never re-installed the ______ ? (rom? image? Odin?)
I read on this and/or other forums that there's a way to replace something, but the instructions were beyond my level of understanding. I would need the procedures to be broken down into steps which don't assume too much about what I know.
I understand how to download a file to Windows, given a URL for it. I understand what a zip file is and how to extract it. I understand how to press hardware buttons and plug in cables, and do these steps in the order I'm told.
I don't understand what I'd use to get the downloaded whatever-they-are onto the tablet to replace whatever-the-other-thing-is so that the touchscreen works again.
As far as I know, Odin is a Norse god.
The only firmware updates I've ever done are the ones that the device does on it's own through Samsung's updates.
I'd deeply appreciate getting this device back since I have extremely limited funds and probably won't be able to buy a replacement.
Thank you,
Linda

Definitely sounds like malware. You have two choices that I see, either root and custom rom or flash back to stock. Since you are stock you'd just be overwriting your existing install. Read this thread and decide your course of action http://forum.xda-developers.com/showthread.php?t=2203309
so a customer brought me an samsung S7 (SM-G930F) and he had factory resetted it thru recovery and then got it to FRP Lock and couldnt get it open. well we were supposed to go thu the thing via sms message. before we did that, i wanted to factory reset it to begin with. well, i turned it off (it was on set language page) and it turned off, normally showed the logo and vibrated at the end. then i was gonna boot into recovery. pressed the combination and nothing. tried to boot normally and again, nothing. tried like everything. every combination, on ac, on pc, multiple times. no led or any kind of response. then i put it in the ac for overnight (8h+) and nothing... its like completedly bricked. friend in samsung store did something, he put a cable on it and told me hes blocking the battery and display etc, took the cable away and still nothing... he couldnt figure it out... i tried smart switch but i cant go to download so doesnt work. is there anything to do ? do we really need to take it to RMA ? No root or any kind of modifications. it was bought in around relase.
small crack on the left bottom on the recents button (button works tho)
i heard he go thru recent software update but it worked after until now.
i did what i do normally, usually all devices boot in to logo or more but this... just brick. nothing.
ok well we got the receipt and went to samsung store, they said it would go in warranty repair, but because of the small crack in there, they want to replace the screen before they can take it... so i need to pay 200 for new screen so that they can take battery out and put it back in... yippee... i would do that easily exept it would lose warranty...
If your warranty is void until you replace the screen anyway, just remove the back and reconnect the battery yourself

Hey everyone who reads this.
I'd like to start my topic with apologising if I post this in the wrong section.
So, I have a LG Spirit H440N LTE for about 3 years now, maybe a little less. I've always taken good care of it, both physically and in updates / security wise aswell.
My phone has been working flawlessly until the last 2 days. 2 days ago i was charging my phone, and when it vibrated (meaning its 100%) I pulled the cable off, and pressed the power button (power button locks - unlocks the screen) the screen didn't turn on. I was like "wow that's strange" but didn't care much, i just kept pressing the button every 5-6 seconds, nothing.
At that point I pulled the battery out, let it sit for a short time and then put it back, start the phone, I felt the vibration (meaning it's starting up) but no screen, so my first idea was that I need to get a new firmware and completely reinstall my phone, as it seems like it got bricked.. for no reason, by itself ? Strange thing but I accepted it and literally been googling for 9 hours now and I find more and more issues.
After I got LG FlashTool, drivers, and even 3 different firmwares, I wanted to start the phone in download mode to start upgrading, but even though I held down "volume up for 5 seconds and then put the usb cable in" nothing happened, no screen, my PC didn't recognise the phone either.
So I got a little bit mad and pulled the cable out from the phone, I wanted to remove the battery, but out of nowhere the phone suddenly started loading in, screen working completely fine, i could do whatever i want, so my first thing was to do a hard reset. After the hard reset I set up my usual stuff (important apps etc) and I locked the screen so my battery won't go down. Little did I know, I ****ed up again, because ever since that happened, I can't get my screen to work again. I tried everything I could but my PC still doesn't recognise the phone (even after a LOT of drivers being installed), charging the phone doesn't do anything. Regardless if I remove - put back the battery no screen, no screen in download - hard reset mode either, it's just completely black.
I'd like to have some sort of help, because I am just completely out of ideas, I really feel like a firmware change could fix the phone, but if the computer doesn't recognise it, I have no idea what to do.

You might be having hardware issues, such as a faulty power button. If you are the type of user that frequently presses the power button to lock/unlock the screen, this leads to excessive wear on the button components, this is why some users prefer to use the "tap to sleep" and "tap to wake" feature, to avoid wearing the power button out. On my LG, this feature is called "KnockOn", it's located in Accessibility settings.

Heu guys,
So I received a P30 as a gift yesterday, it said it had an update so it downloaded. Then it said it needed to be at 20% to install the update so I just left it until later when I could get to a charger. The thing is, I also didn't have a sim card in it.
I pulled the sim slot with the phone turned on (install pending) , and as soon as I did that I got a new black screen of death, nothing like in any of the videos online.
This one allows me to interact with the screen, however the entire screen stays black except for about 50% of the top (like I can see 50% of the battery icon) notification area. The tiny section of the screen that turns on also looks sorta wonky, like screens often do when they get water damage.
I've been able to turn it off, by guessing where the power buttons were. I *think* I even got it to the hard reset menu, but not being able to see, I can't type on the screen. It does react to the soft reset (power + volume down) but when it turns back on, it won't even show the logos on boot, everything still stays black minus a section of the notification bar.
Is there a way to do a hard reset without being able to interact with the screen at all? Can I do it using my computer somehow?
I know the screen is not broken because I can interact with it. Also on 1 of the 30 soft resets I did, the screen flickered some sort of error message for a quarter of a second, so fast all I could do was see it was text.
I'd just return the phone but it was a friend's old work phone and there is no way to get a replacement.
I recommend you to use Hisuite on a computer, try to connect the phone (I said try because you must select the type of connection on the phone). If the phone connects to Hisuite, use the recovery option to reinstall the default firmware. Good luck!

this might be my only option. I was trying to find something just like that. Couldn't figure out if there was a software for it or not. Thanks will try when I get back to a computer tomorrow!
Hi everyone, I'm throwing this out there because I've run out of ideas about what has just happened to my U12+ (64gb) today.
I woke up and used my phone as normal, caught up on Twitter and the news, the usual apps etc. nothing untoward. The same routine I've had with my phone for the past 18 months of owning it with zero issues. My handset is stock OS (Android 9) and so not rooted or anything like that. Virtually all the apps I use are standard issue from the Play Store, nothing really "out there" and I have BitDefender installed to look after security. Same setup I've had for over a year. The battery was around 35% so I plugged it into my wall charger while I went off to grab some breakfast. When I returned a couple of hours later the light on the handset was green, I unplugged the charger and attempted to unlock it with my fingerprint.
The phone asked for my PIN, no big deal so I entered it. Black screen. Tapped the power button again, it requested my PIN again, I entered and... black screen. Okay, I was a little bit concerned now. I held down the power button so the haptic buzz occurred, held for 10/20/30 seconds, a minute... nothing, no restart. Tap the power button and it asks me for my PIN again and shows yet another black screen. I held down Power + Volume Down but again, nothing and no restart.
I asked someone to call me, the screen came to life and I could take the call but each time I tried to pull down the system tray in order to try and reach Settings to restart it asked me for my PIN, I entered it = black screen. The call was unaffected.
I removed my SIM + microSD card tray = same deal as above.
The phone is clearly responsive in some way and the screen does display to ask for my PIN but I can't get into it in order to reboot it. Extremely worrying.
Does anyone have any advice? At the moment I am faced with the prospect of simply allowing the battery to run out so the phone shuts down naturally but that is going to take the best part of 2 days.
I'm really disappointed because I was planning another 1-2 years use for this handset as I just bought a 1TB microSD card which has been fine in the phone for weeks so I don't think that's the cause. It is also genuine SanDisk.
Any suggestions or advice? Thanks in advance.
Hello, I hope you have made a backup with google backup recently... This does not happen often on android, but sometimes the system could have a problem. You can try this go the bootloader with the power and volume buttons , after recovery.. after apply a wipe data/ factory reset.. is will make a factory reset of your phone except the sd card. You should by fine after that and profit again.
Thanks, I appreciate your reply.
At the moment I am running the battery down until the handset switches off naturally. When it comes back on I will try to launch the phone normally, if that doesn't work I'll run the battery down again and attempt to reach the bootloader.
My photos are backed up to the cloud, I may lose some text messages but I managed to transfer the majority of my 2FA over to another Android device bar one.
At the end of the day if it's a choice between wiping it or a bricked/unusable handset then I don't really have one. What a pain.

At the moment I am running the battery down until the handset switches off naturally <----- why that??? Even on a bootloop or a black screen you can reset it hold the buttons power and the volume, you can go on the bootloader.

The first thing I tried to do was hold down the power button or the power button in tandem with the volume buttons but the handset won't restart. I tried loads of times holding it for different amounts of time and... nothing.
Trust me, I tried.
The only way I can get the device to switch off is by draining the battery. I'm almost at 20% so it shouldn't be too much longer.
Well I already got a black screen after flashing a module magisk.. I have holding the power button and the phone have restart no problem, same thing on bootloop. You need to be sure to hold the button correctly.

Yeah, I'm certain I was holding the buttons correctly. I tried about 20 times using different combinations just to be sure but the device would not restart. The haptic shock buttons are one of my least favourite features of the u12+, it's got to be said.
Anyway, the phone ran out of battery about 15 minutes ago. I left it alone for few minutes and switched it back on. It allowed me back in and the device appears to be fully functional again. I can unlock by thumb print, face or PIN without issue.
Basically, it's fixed. My only concern is I have no idea what caused it or if it will happen again.
Thanks for offering help though, I appreciate it. I'm not sure if this thread can be closed/locked now? I'll look into that.
Cheers.
Yes.. i love the buttons too i never got a problem with this. Great if is fixed! Maybe make a factory reset the next time.
I am wondering if the new flagship have haptic buttons too.. htc will announce it Tuesday.
