hey guys, I have a problem with the mi a2 lite. After having sbricked and installed 10.0.9.0, in the initial configuration, if I select something, the screen opens and after a second the screen goes black, remains black for 5-6 seconds and then returns to the initial configuration screen (the one with the word "Hi there" where the language is selected.
What can I do?
The last time it happened to me was when I downgraded to 10.0.3.0 (same symptoms, the screen went black and left black for 5-6 sec), I tried to reinstall the 10.0.3.0 from fastboot and the phone got bricked, I had to enter edl to fix it
I made a video if it can help

Hi,
this afternoon i was trying to flash the ROM of my LG KS20 when i read the combination to enter in the engineering menù. So i looked a bit through the different menus until i click on "Backlight On-Off" option in the "LCD Test" menu.
At this point, the screen on my LG turned off and now i can see that phone still working but the screen remains always black. For example if I click the power button on the right of PDA, the 2 button turn their light on but the screen remains black.The same is when i push the button of photograph machine...if I wait a few second and push again the button the PDA take a photograph because the flash work and i can hear the sound of shutter.
I try to hard reset the PDA, but all remains the same....what can I do???
Please help me
Thans a lot
Maybe you could try to install a software called "My Mobiler" (http://www.mymobiler.com - it's freeware). With this software you could access your KS20 through your PC and try to revert the settings in the LCD Menu?
thanks a lot....last night I found MyMobiler searching somethings for view the device screen on my desktop. After I installed it on my PDA (with some little problem to give the ok for the installation on PDA), I can see the device desktop and so I do the same procedure to restore the backlight.
So now all works fine.
Thanks
Have the same problem
but i not lucky... can't press ok on the black screen, can you publish screen with instalation on PDA to try locate the OK??
really thanks
On your screen, you should see the standard view of the installation process.
So, when you launch the install from your pc, you have to immagine the screen of the acknoledge of the install. try to push in the left corner at the bottom a couple of time, then you shoud see the today screen on your pc.
Same problem
I have the same problem, but I need to enter my pin, but I'm not able to enter it because I can't see anything...
And I change the USB settings in the engineering menu so I cannot connect with ActiveSync :S
Any idea?
Thanks a lot.
I just rebooted today without making any changes, and once my OP3 finished rebooting, I just got a black lock screen with no response whatsoever. If I hold the power button, I get the reboot dialog, I can take screenshots and they save, and the capacitive buttons react to input. When I reboot into safe mode, the exact same thing occurs, except the lock screen isn't black and says "safe mode". I literally just can't use my phone, period. If I boot into TWRP, I can still access my files after decrypting. It just seems like systemui refuses to start, and I'll have to reset the phone. Has anybody else experienced this?
Could you solve the Problem? Had the same. Only solution for me was full reset.
Flash a newer Rom and see
I do run two devices (SM-P905) on LineageOS 16.0 and Nova Launcher Prime – usually without any problem.
Yesterday we choosed another photo (don't remeber the format...) from a gallery for background picture. Since that moment we are unable to use this device.
After reboot we get a blank login screen (= just black).
After deleting Dalvic/Cache we get a blank login screen (= just black).
After rebooting in safe mode we get a blank login screen (= just black).
The device does boot ROM (=Samsung logo) and LineageOS (Lineage logo) correctly. We do not get a login screen at all.
When pushing the on/off button I get the regular menu for shut down/restart/abort
Any solution for that issue without doing a factory reset?
[updating LineageOS 16 for actual November version did not do any changes]
Hello, I have a huge problem with my Samsung A50: it crashes in the TWRP recovery home screen and any key combination I face restarts and returns to the usual screen again. The sequence of the screens are these:

How do I reset the phone? Thanks
Hello,
sorry to write here, I cant find the C21-Y section.
Direct question: is there a way to perform a factory reset not having the possibility to do it using the combination VOLD DOWN + POWER BUTTON and NOR using the standard Android UI?
Note, not activated debug mode
For more details see here below
I recently did a factory reset in "normal way", I mean using the standard Android user interface through normal menu.
Then, I changed only 3 things (without considering the minimum settings required at the first boot): show battery percentage, start black user interface menu and then after selecting the high contrast display... the display became black.
The display is responsive, because the phone vibrates if I touch in the position of the 3 buttons (back, multi, back).
Then, waking up the phone I can see the black smoothing on the display (hoping to make myself clear...) and I'm able - fortunately - to switch OFF the phone (basically touching the display in the right position and swiping to back, after holding a little the phisical on-off button).
Then, the display is working in the boot sequence (I can see the Android logo and the Realme animation): it stops once the Android system is loaded.
So, I tried booting the phone with the combination VOL DOWN + POWER BUTTON but it doesn't work... It seems an issue that afflict some pieces of this phone (read in some post, video I searched before writing here)
Well, how I can in this situation perform a factory reset?

Click to expand...
Click to collapse
You should be able to boot in to recovery mode where the device is powered off state and when you use key combinations to do
Keep holding the keys even if you see splash screen, untill recovery screen appears
You can also try holding volume key and connecting to computer via USB cable, without needing power button.
Unfortunately with this phone (or the Android version installed in the one I have) have some issues and... butroon combinations are not working
I think I've tried in every way, different combinations. No luck
Both (button combination and black screen) seems to be "common" (search on youtube black screen C21-Y) and the only way is to flash it and/or force the factory from PC (I don't have at the moment understood if for thios phone the only factory from PC is working)
Being a sw issue I'm trying to intercept Realme support, before trying any flash or something similar... but after the first answer to my mail they didn't come back again
I just call Realme support for a similar issue on C21-Y. They tell me this model doesn't have a recovery installed and olny way is to send back to factory and they will provide a factory reset.
What a bad product, no words.
Follow this, it worked in my case (without flashing the phone)
