At start up I get a black screen the says Samsung with a unlocked lock with the word custom under it. After that the phone starts normally and runs fine. I just know I tried to unlock my ATT phone with a different sim and the got the wrong unlock code from ATT. Since trying that I get this black screen when starting up..
Hello everybody here, let me explain my very weird screen issue. First I have an LG G2 D800 from AT&T Unlocked I bought it at Amazon on December. This began like a month ago. I was using my device normally and it freezes the screen, for example if i was playing music It freezes like a screenshot but if a pressed any button i could change the next song. This was getting more often but now my phone doesn't turn on the screen. i try to power off it shows me the LG logo after bootanimation. But Screen does not response it tries to wake up but it can i see hoe the black screen get illuminated but it only shows black.

Does your pc recognise your phone? Maybe you can factory reset it with adb

Well sure I used Lg Flashtool with the download mode with 4.2.2 stock but nothing happens still the same. Weird is my Screen shows LG logo, but then it gets frozen on LG logo, phone seems to be working because i can receive calls and sounds system work fine. I think is like a hardware issue. but the LCD screen is good because it shows the LG logo. But then It just freeze.
Here some images
Title says it all. Phone is completely stock too. I was at work on break, sent a text, and then put it in my pocket. Checked it once more and the screen wouldn't turn on. The phone was at half battery and everything. Just got the phone 2 days ago new. But nothing will boot, no recovery. Not even connecting the charger. I'm just wondering if anyone else has had this issue. Makes me feel like LG isn't that reliable, coming from an HTC.
2 month into a new V20 (H918 t mobile), I now have about 6 grey boxes on the display, it sometime bleeds into the second display as well.
I was on NSS 6.5, after having the issue I tried factory reset and jumped on to WETA 5.04a. Problem persists.
Tried pulling the battery a few times also. The grey boxes shows up first during the LG boot logo and sometime changes in brightness and stays permanently on screen.
My input is way off too, sometimes tapping on the screen does nothing.
My suspicion is that the hardware went bad, did any one else experience this issue?
Please let me know if this is fixable, or do I need to RMA with LG.
Also do I need to LGUP the KDZ before sending it back to LG?
Same problem with another 2 month old LG V20 (H918) . After loosing a bootlooping G4 and a G5 with the GPS malfunction, I will no longer consider LG devices.
I did a factory reset on an unlocked Sprint LG V20. It is now in a state of… I have no idea what state it’s in but it’s completely stuck. Please help, wise people! Obi-Wan’s, you’re my only hope.
(Forgive me if this has been covered elsewhere. I really did search first.)
HISTORY:
1) Bought an unlocked Sprint LG V20 off ebay. Worked great for a year and a half with a Consumer Cellular sim.
2) It suddenly got molasses slow so I did a factory reset (power off → power+volume down → wipe data/factory reset → yes).
3) On power up, the Sprint splash screen was gone, all Sprint apps are gone, phone no longer recognizes sim (invalid sim).
4) I thought it might be relocked by Sprint despite any Sprint evidence. Contacted Sprint, said they wouldn’t unlock without the original phone number. Contacted ebay seller, he didn’t have it.
5) Out of desperation, only because I read about somewhere, I dialed on the phone ##72786# and restarted the phone as if for a factory reset. After the initial LG splash screen, Recovery Mode appeared, followed by the usual recover/reset menu.
NOW:
1) Whenever I do power off → power+volume down with the Consumer Cellular sim in, I can select Wipe/Reset or Reboot Now and the result is the same: 1) eventually, it gets to setup, starting with Talk Now (press Next), Language (press Next) to Use Wifi (setup successfully, press Next), to the Configuring phone screen.
2) This is where I have no idea what state it’s in. It will just stay on the Configuring screen and hang. Forever. Until the battery dies. The only button that will work is the Power button. I’ve selected Power Off and Restart many times, and the result is the same: the setup routine all the way to Configure Phone page to complete hang.
3) Incidentally, if I do step 1 above with the sim card in, the Configure Phone takes a lonnnng time until it eventually shows a screen saying to please insert the sim card that came with the phone and reboot. Doing so starts everything from step 1 all over again.
I seem to be in a strange state, not locked out of Sprint or Google, just locked out of making any changes to the phone other than the Recovery Mode screen. Is this what they call bricked? Ugh.
If anyone has any ideas, I’d love to hear them and would be wicked grateful!

Sounds like a NAND failure
Sent from my LG-H910 using XDA Labs
Thank you for the lead. I've never heard of that before so I just did some reading and it makes sense. I haven't searched on the board yet, but a quick google search doesn't bring up much in the way of fixes. (Although what's out there suggests it being a big problem with iPhones.) What is out there is based on the premise that you can download things, which I can't.
Do you know of any resources for fixing it? I searched on "lg v20 ls997 nand failure fix" but I suspect, based on how little it brought up, that another search string might be more helpful.
Have you tried to reflash any update on it......a little while back I had a g4 that was boatload unlocked did a similar thing but I got a green screen telling me that the phone has made a nandroid back then when on to complete a full brick with nothing just a paper weight.......
Excellent, Stinka, thank you. I'm just not sure what reflashing an update means... I'll look it up, but any advice would be appreciated.
To be honest, I don't even know what a bootloader is and have wondered if I should select it while in recovery mode. Again, I'll look it up.
UPDATE: The phone is now in a state of working as a mini-pc but not a phone. Not sure I could recreate it but I started clicking things all over the place when it was setting up. It now works with apps and gets wifi but still says Invalid Sim. I only have the Consumer Cellular sim so I can't test it with a Sprint sim to see if that would work. But with wifi, it means I can download things that could help. If that changes things and provides other options people want to suggest, I'm all ears! (and thanks again for your help)
