[Unfortunately, System UI has stopped] Problem - Android Q&A, Help & Troubleshooting

Hello there, I'm a fairly new member to XDA fourms. I seem to have a problem with my LG Leon from Metro PCS. I get this com.systemui has stopped error countless times, I tried rebooting my phone but no luck at all. I tried factory resetting, but the same problem occured. I can't to seem to get in recovery mode with the phone, I tried holding the power+Down volume buttons down but no luck what so ever. But, when I factory resetted. it took me to the custom recovery and then went onto the LG start up menu. I'll appreciate any help.

Can't get into recovery/download mode..constant rebooting...power button problem?

I tried updating my ROM (to CM11) and came across so many issues. For some reason, it kept rebooting and then at one point just got stuck at the animation screen. So I decided to just start everything from scratch again.
I tried to get into download mode to install CWM, but the phone kept shutting off as soon as I got in. After MANY tries, I finally got in and got it installed. When it finally worked, I tried to get into recovery mode and the same thing happened. Finally after many tries I was able to get in there too. I then installed my ROM and then when it finally loaded, the phone then shut off and tried rebooting but wouldn't get passed the animation screen again.
I did a lot of research and found that some people had their internal power button either get stuck or become defective. Mine clicks so I don't know if that's the problem, but the symptoms that others have mentioned have all happened to me.
Does this in fact sound like a button issue to anyone? Any help is appreciated.

Seems like your hardware button could be broken, I would all do in this order:
Download Philz Touch Recovery from here: https://goo.im/devs/philz_touch/CWM_Advanced_Edition/i9300/
Official Firmware from here: http://www.sammobile.com/firmwares/3/?download=28378
Flash Philz touch through Odin
Reboot to Recovery, selct "Clean to install a new rom"
Wipe cache and dalvik cache
Go to downoad mode and flash the md5.tar file through odin

How to Venue 7840 bootloop problem?

Hello, as you can see the title, because of my stupid friend, my tablet can't work well now..
He set the password in my tablet and I didn't even noticed at that time.
After I asked him the password, He told me He forgot it.
Unfortunately, that was true, so for unlocking the tablet, I did the wipe data and factory reset.
That was the problem.
After did that, my tablet starts to bootloop, just showing the dell logo.
I tried to access the recovery mode again, but all I can see is that the broken robot, and can't go next step.
I searched the similar threads and I found that if I can approach the fastboot menu, it is able to unbrick the tablet.
I could approach that menu which I can choose normal boot, power off, reboot fastboot, and recovery mode, but that's it. I pressed the volume buttons (up & down simultaneouly) tried many times to recovery mode but after did the factory reset, it couldn't do it again.
Could you give me some advice to solve this problem? I'm looking forward to getting the solution. Thanks. :crying:

I followed the steps which you told me, and I could flash that files.
But after did that, it made the tablet freeze, not bootloop.
The screen just shows dell logo and didn't work well. I waited for 15 minutes, even more but it didn't work well.
And still I can't approach the recovery mode. Just I can see the broken robot..
Is there anything I can do? Hope to get advice :'(

My phone is bricked, heelp! lg g2 mini D620r

Hey guys, I have some serious problems.
So after reading threads and forums for 3 days now, I still can't make my g2 work again. So the problem is that my phone, out of nowhere just turned itself off, and now is in a bootloop. I had that once before, I did a factory reset with the buttons, and it was working again. Now it happened again, but when I try to do a factory reset, it freezes, and doesn't do anything at all. I tried this several times, nothing. I want to say, I don't know anything about custom roms, ive never tried to do a firmware update on my own, or tried to unlock bootloader, so you know I can't even do any of these. I always left my phone's system in its factory shape. But still this happens to me, and I can't boot into download mode even, my computer recognizes my phone as an USB charge only interface. I read about lots of solutions, and i can't even do them because my phone doesn't load the download mode. I hold volume up, plug in the cable, it tells me to keep holding, and after 30 secs, it goes to something thats gotta be fastboot mode (the last entry is fastbootrocessing commands). I don't know anything about developing or what, so please guys help me

Lg P769 Stuck on Boot Screen. Bricked??

I had flashed a custom ROM on my phone maybe a few months or a year back. I think I remember trying to reflash it trying to fix some bugs but it ended up getting stuck in a boot loop. I think after several tries it booted into TWRP recovery and I had factory reset it (these details might be a little fuzzy as I tried all of this months ago just never got around to posting this since I needed to focus on schooling) but now when I try to boot it, it just boots to the LG logo screen and gets stuck. I can boot into S/W upgrade mode and I had tried to restore it using the LG support tool but it recognizes it as the latest version and will not reset the phone. So right now I am at a loss and need some help to restore the phone and to hopefully flash it again. Thank you!
