Device stuck at "unfortunatly system ui was stopped"

My father device suddenly decided to get stuck right after boot with the above error message.
I tried reboot into safe mode but got the same result.
I tried to connect it to my PC using abd(after installing drivers), but for some reason adb didn't recognize the device (fastboot however did find it).
Any ideas before doing hard reset?!

System does not mount and i need to extract files by ADB

hi
While working with the device, it reset without prior warning, and since it trying to start and when the Google logo disappears and the animation stage arrives, 3 seconds later it turns himself off.
I entered into the Recovery mode and cleaned Cash - did not help
I thought to take out the battery in case something might be stuck in my memory but I still have not done it because when I dismantled the small panel (on the part of the camera) I accidentally turned on the device and it showed me that it upgrades the apps, which was a good sign for me so I closed the panel and waited for it to finish The 147 applications. At the end he turned himself off
I did not proceed with the matter of dismantling the battery.
I have the default recovery, I did not install recovery applications that expand the possibilities in the recovery mode.
and i don't remember if i turned on the USB debugging.
I decided to transfer the files (pic's, whtsapp) by ADB befor i try the factory reset
but I get sideload instead of recovery
C: \ adb> adb devices
List of devices attached
R ********** sideload (I changed the stereo to asterisks)
and every command I try to run I get
error: closed
Does anyone have an idea of how to copy files or repair the system ?
thanks

You should be able to bring it to fastboot mode by powering it off, then holding Power, Volume up an Volume down until the robot appears.
From there you should see the device with "fastboot devices". You might need to install some drivers at that point.
When in fastboot you should be able to start TWRP with "fastboot boot twrp-3.1.1-0-manta.img". When in TWRP you can see /sdcard in Windows or you can start Advanced > File Manager and copy your data to a USB stick.

thanks bornheim2
i succeeded to load the TWRP
but when i unplug the USB for plugin the OTG the screen start blinking and the devices turned off.
i have charge the device all night
so my guess is that my battery is bad.
can i use usb a male to usb a male adapter
or Hittime smart 3 in 1 Micro USB OTG/Sync/Charging cable
( i can't put links )
to connect the device with OTG to the computer for power and for transfer data to the computer ?
thanks

You should see the device in Windows when TWRP is running (and the device is charged by the PC). That should be enough to save your files.

i don't see it on windows (computer)

That might be a driver problem. Do you see it in Device Manager on Windows? Probably with a yellow triangle?

it's good in the devices manager "Android Bootloader Interface"

but after the TWRP it upload, the devices no longer appears in the device manager
and the screen is still blinking

when i run the "fastboot boot twrp-3.1.1-0-manta.img"
it turn in the device manager to "Android ADB recovery interface" and after 1 sec is disconnect

Galaxy A3 A300F Too many issues. Look at the list.

Hello guys, my friend give me Galaxy A3 A300F. This device has many issues.
1. Device stuck on black screen with text "Samsung Galaxy A3" in middle & "Powered by android" in bottom. (I'm talking about the very first screen)
2. After 20 minutes, it proceeds to coloured samsung logo animation and boots up.
3. I noticed that it heats up during booting process & after too.
4. After boot up, it will restart automatically after few minutes.
5. If it holds up after booting for few minutes, i tested whether my computer detects it but i got no signal. I check it under DEVICE MANAGER and i found nothing. (With & without USB debugging enabled)
6. When i connect it to computer, the device start charging but there's no notification of USB plugged in.
7. I dial up *#0808# or whatever to configure usb settings to USB + ADB. Still there is no connectivity.
8. No IMEI found.
9. I put it in DOWNLOAD mode and connect it to PC but still there is no detection.
10. The still have access to stock recovery but no sign of detection. No adb devices found.
11. And ofcourse, ODIN did nothing.
I think that if somehow, PC detect it, then i'll do something.
Now, if you guys have any method left, plz share it. I'm so interested to fix this device. Waiting for your messages.

First thing that you need to do is to talk with your friend if he has a valid warranty and tell the problems to him.
Method 1 (if he can't fix it, then it's your time to make a difference)
If you ever get the connection, try to google as fast as possible on how to install the stock rom for the A300F to your device (if you need any help, I will... just toss me a ???PRIVATE??? message and...yeah :good: )
Just try, it's always good to try and since this is the socail era, you have help just everywhere in the internet

Yoga Tab 3 plus (YT-X703F) - "unfortunately system ui has stopped"

Hi there,
Since the upgrade to Nougat 7.1.1, my Yoga Tab 3 plus (YT-X703F) is showing the following error "unfortunately system ui has stopped" each time I plugged the usb charger. The screen stay black until I disconnect the usb cable. So far, I tried without success
1) Factory reset via the reinitiation menu - Error still present after reinitiation
2) Boot into the recovery console - Not working. The bootloader hang and does not initiate the recovery console. I can restart the tablet into the normal mode after the battery pull method or via fastboot reboot command. The recovery console has been either erased or corrupted in the upgrade process.
3) ADB and Fastboot - not working. I cannot authorise the device since the screen is lock into black as above and both tools return the tablet status as unauthorized (adb devices or fastboot devices).
4) Boot in safe mode. Error is still present. I cannot access the tablet when charging and/or plug to a computer via USB.
Any help would be appreciated...

Unable to boot Xperia Z3 Compact? (Able to boot into fastboot, not recovery, no logo)

Messing around with my Z3 compact, which was already rooted and I'm sure the bootloader was already unlocked when I first rooted it. Anyways I tried to install Magisk for testing purposes, now I have a non-functional phone. Now I can't boot into recovery mode (I had TWRP) or into the regular mode.
I can boot into fastboot mode (plug in USB + hold Power & Volume UP --> 3 Vibrations --> Blue LED Notification). I checked using flashtoolx64 and it does detect the phone is in fastboot mode.
However when i try to flash the stock firmware, where I have to restart the phone in flashmode (Power off --> hold Volume Down --> Plug in USB), Windows says there is an error recognizing the device. and when I check device manager, it says the USB Device entry is: Unknown USB Device (Configuration Descriptor Request Failed). Could this be a driver issue?
I couldn't find any other solutions for restoring the system without going into flashmode, because it looks like i can't even get that working. I would appreciate any solutions that utilize fastboot mode, since that is the only mode I can get into with the computer recognizing it.
-Edit 1-
Silly me, it turns out I was able to get into flashmode afterall (Power Off > Volume Down > Plug in USB).
After double checking and re-installing the Sony Xperia USB drivers, I thought the phone was done. I tried plugging in the phone using the back USB ports instead of the front and voila flashtools can push the stock firmware. My guess is that the "Configuration Descriptor Request" error I saw in the Device Manager was because I was using the front USB ports on my PC.
-Edit 2-
Apologies, clicked on the wrong forum when it should have been posted in the troubleshooting forum. This thread can be closed/deleted since I figured out what's wrong (see edit 1)
