Phone not booting correctly but is still on - Xiaomi Redmi Note 7 Questions & Answers

So i once took my phone to charge before going to bed and the next morning the screen was just black and the phone was "dead". The screen was black, nothing reacting. Rebooting was possible, but screen still black. I went through a whole night trying to figure out whats wrong and lastly i flashed the stock rom using the recovery tool and accidently ended up locking the bootloader with a non working screen.
Today the replacement screen arrived, i connected the new one, restarted the phone and still its just the screen lighting up a few seconds then turning off as soon as the redmi should appear. It does look like its not the screen but still something in the software. Is there anything i can still do to rescue the phone or is it just dead?
greetings

Try going into the stock recovery mode through hardware buttons (Hold Vol+ and Power) and try and factory reset.

Black Screen

I just realized that my phone was like... dead. It turns on and I can synch with it in windows, but the screen is completly black and without image. I can receive calls. Before this I was not able to turn it on. Then it turned on and showed something like ChipID error, then it went black until now. When I plug it to the computer it doesn't seem to be charging (no orange light) I have hardspl in it. Also I didn't do anything special with it, I simply foud the phone like that today, it has been weeks since I flashed a rom or something. Any ideas?

Could be a faulty screen. Have you tried a hard reset
Yeah, I also did some hard resets. I think the screen got damaged at some point when I was unable to turn on the phone. Eventually when it worked it showed some weird error after startup in a message box. After this allways black screen (and no backlit and orange light of charge), also reflashed because the thing is working, it vibrates on startup (after 25 seconds) and plays the htc tune, it enters windows mobile too and I can receive calls but it keeps it all black.
I contacted the customer support of the online store, I will simply ask for a repair or replacement.
Thanks.

[Q] MIUI-1.6.10-demonSPEED-v1.1, WILL NOT BOOT

So as the title says i currently have MIUI 1.6.10 demonSPEED v1.1 ROM and it is not booting, just completely unresponsive to everything i could think of. Im just throwing this out there to see if this has happened to anyone before or if there is a way of fixing this issue. I don't believe it has anything to do with thederekjay's rom just some unfortunate event. Anyway i fear it is possibly bricked and that i am gonna have to shell out the $150 to get a new mt4g from the insurance. Details follow...
So have had this rom for about a week now and has been working great. However this morning i was on the browser reading the news and it became unresponsive. After i let its display turn off (i just left it alone) i used the track pad to wake it. It was slow but it did show me the lock screen. When i attempted to unlock with a swipe down i felt the vibrations but the slide lock didn't budge. I then tapped the power button to turn the display off and tapped the power button once again to turn it on but nothing, just stayed black. I tried a soft reset by removing the battery, placing it back in, and powering back up. When i did so the t-mobile mytouch 4g boot image w/ the white background came on then went to an android image (lighting up a through d, looping) but then it just remained at the android image for five minutes! So i tried a soft reset again but the same thing would happen, act like it was gonna boot up completely but then gets stuck at the android image. So then i tried removing the battery and booting into recovery (via power, vol down, trackpad) that time the t-mobile mytouch 4g image would appear but after that the screen went black and after that every attempt with either the soft reset or boot into recovery wouldn't do anything at all, just a black screen as if the battery wasn't in at all. Its been like that all day and i can't figure it out so if anyone knows some info i would greatly appreciate it thanx

Dead Lumia 520, screen is damaged, help needed.

I have obtained a water damaged Lumia 520. I opened it up and dried it while also clearing any oxidation from the various contact points. The phone displayed the bolt+gear icon on screen but the screen kept flashing and fading. I figured the phone needed the firmware to be reflashed so I downloaded the software recovery tool and it detected the phone and flashed the firmware without error. Then the phone actually worked albeit with a black screen, I could hear the little noises and stuff so it was working under the black screen. I figured that maybe the screen could be salvaged by cleaning the contacts and letting it dry up completely, but after I put the phone together it wouldn't work anymore at all, it basically turns on for a few seconds and turns itself off. The software recovery finds it and I can reflash the firmware but it still doesn't work. I tried checking all the internal connectors but now there doesn't seem to be any way to make it work even with the dead screen.
Is there something I need to touch on screen to make it work? I never had a Windows Phone so I don't really know and I can't see the screen. And do you geniuses know what might be wrong with it and how can I tell if it's just the LCD that has been killed by the water or if the motherboad might be FUBAR as well? What could be causing it to turn off after a few seconds? The battery is definitely not dead as I left it to charge for a long time.
Actually I just managed to "fix" it. The screen comes on after I cleaned the contacts and messed with it a bit, it just looks really bad and it's full of line but I can see what's on screen and use the phone. My issue now is that the bolt+gear icon appears at every reboot and doesn't go away. The only way I have to boot the phone normally is to hold camera and volume down after I reboot it. What does this mean? Other than that the phone seems to be working perfectly once it actually boots.
I just managed to bring it back to life completely. Screen contacts were water damaged but I managed to get them working again and now the screen is perfect. It kept getting stuck on the bolt+gear icon after every reboot because the volume+ button was stuck but I managed to unstuck it and now the phone is perfect. So yeah if you have a flashing screen after water damage check the contacts, if your phone doesn't boot and keeps getting stuck on that icon try to unstuck the volume+ button.

Phone vibrates but wont show screen?

So after i had sucessfuly rooted my galaxy, unlocked the bootloader and installed cm13 2-3 hrs later cm 13, starts to turn off the screen but stays working since i had it connected to pc and i was able to move files back and forth... now since i couldnt get it to stay working i decided to restore using twrp but after slidingto confirm the restore the phone immediately shuttled its self down, so i decided to flash stock rom which it did flash but with screen off while odin was doing its thing.... now when i turn it on i can hear sound but no image and for the screen to work i have to connected it to a power sourse first then turn it on but stays stuck on verizon screen loading!! so i flashed stock rom again but again same thing!! EDIT now afer it went past verizon screen it said set up wizard stopped working.... i have flashed stock rom like 5 times now..
Current status of phone: phone will turn on sometimes with visuals but most of the time you can listen to it booting with no visuals untill it reaches verizon and just hangs there, last time booted some kind of accecibility feature that telling me what the phone was doing at all times, just right after the verizon logo saying " set up wizard stopped working"
- i can access download mode and recovery mode sometimes with screen working and other times without it working so i might just be soft bricked maybe bootloader brick?
Flash stock firmware with Odin and immediately after flashing, wipe data/factory reset in recovery. Then reboot

This actually worked and booted the phone thanks man... however i dropped the phone and now when the screen do turns on but after couple of minets of usage like 3 minets the screen shuts off but the phone stays fully working, does this means that replacing the LCD will fix this? or maybe something inside is loose as a result of the drop?
Edit: actually after screen shuts down and i leave alone the phone shuts down completely and restarts when i attempt to push power or home buttons and after it restarts the screen is not visible anymore... so to get the screen to show again i have to remove the battery and wait couple of minets to put back on and sometimes this gets the screen to show but some times it doesn't... if i remove the battery and immediately put it back on this wont work i should mention

Try opening it up with a heat gun and checking for loose connections.

Oneplus 2 screen faulty? Please help

Hey, I broke my op2 screen so I bought one from ebay, teared it apart all correctly (i'm a computer technician), installed the new screen, all fine but a weird symptom appears:
- It boots and shows the Oneplus logo then screen all black. I know it booted cuz the touch buttons work and i can ear the sound of unlocking etc. Also if i plug into the pc I can easily access its memory.
- If I try to enter recovery I know it enters too but the screen is all black, the only mode I can see the screen is fastboot mode and it stays and acts normally.
- I did a full reset on the phone back to stock via adb, thinking it was software, its all stock now, still the same occurs
Im out of ideas so I just think the screen is faulty from ebay, did this happened to anyone?
Thanks in advance
