[Help] Phone not recognized by PC - OnePlus 5 Questions & Answers

I was charging my phone few days back, and after about 2 hours I checked into my phone and it was stuck showing my background with no applications etc. It did not respond to any button presses except holding down the power button.
After trying to turn my phone back on it got stuck at the OnePlus spinning logo. I shut down the phone after about 30 minutes of spinning.
I was able to access fast boot (bootloader) menu and recovery menu, and even tried clearing my phones cache and system data in the recovery menu but this didn't help.
I read that I might've 'bricked' my phone and I tried some guides on the internet on how to fix it, but I was unable get my phone recognized by my computer so that didn't work out either.
If I have my computer plugged to my PC it does indeed charge, but my device manager doesn't show any new devices, nor do I get any pop ups for new device detected. This is keeping me from even trying to unbrick my phone.
thanks for all the help in advance!

[Q] LG G2 D800 ATT - Bootloop

Hello.
I have a problem with my LG G2, it got bricked yesterday. I was playing some game and suddenly it turned off and keep restarting on LG logo. After couple tries with powering off and on it turned on, I wasn't at home so I could not do the backup. After an hour bootloop started again, today after >30 tries it turned on but unluckily I was at the gym at that moment, after 30 minutes bootlooping started all over. I tried over couple hundred times but to turn it on and do the backup but no luck.
I am able to get into download mode but I dont think it's the full one, when plugging into computer it maked couple hardrives saying they need formatting
LG is detected as qhsusb_bulk in device manager.
I am able to get into factory settings but I don't have CWM. My device is not rooted. Probably it doesn't have usb debugging on.
Oh and theres one strange thing, I cannot turn the phone off (during bootloop) when it's plugged into charger, if I hold power button a red led blinks 8 times.
Is there any chance I could backup my data or fix it without erasing? It's very important because there are over 3 thousand photos.
I will be really grateful for help.

Nexus 4 SoD / Display not working anymore

Hi everybody,
i think my Nexus 4 died yesterday Was listening to music while i was in the workshop, suddently music stopped and the display wont turn on again. Tried to restart it a couple times but nothing happend. Than put it on the charger for a while, than my computer. There, it showed the charging animation if your phone is completly shutdown and when i pushed the start button it booted up quiet normaly, but "optimised" my apps again. After unlocking the Sim card, i pushed the homebutton and it crashed again. Since than, no picture on the screen anymore. It starts up(vibration from boot) and is even recognised via usb "remove mako" but i couldn flash a stock image with the nexus toolkit, it stucks in "waiting for device".
Was running CM 12.1 from end of june.
Is there anything i can test if my LCD died, or flash a stock rom without any displayinformation?
Best regards from me and my good old Nokia E51, which is no back in Service again.

Can you get in recovery mode or anything else accessible with button combinations? What happens when you hold power and volume down and up together for a couple of seconds? Try holding them for 10 secs.

Hard Bricked Samsung galaxy s7 edge

Hi! I managed to hard brick my galaxy s7 edge and i wanna see if someone here knows if its hard bricked or soft.
Got root and had renovate rom 2.0 ( n7 port) then i wiped my phone and flashed renovate 3.3 (s7 edge stock)
my phone worked fine on startup and i started to restore my old apps through gmail. i thought it would take a while so put my phone in my pocked and let it be fore about 20 minutes then when i took it up it was complete dead. i had about 67% before it died i tried everything (vol up down home all together) for at least 15+ sec. had it charge over the night ( i noticed that the phone didnt get warm or any leds shown) in the morning i tried everything again and nothing. when i connect my phone to my computer i hear the connect sound and then it disconnect a sec later. if i hold power button down and connect it ( and dont release power) my computer recognize it as onyx8890 and if i release powerbutton it disconnects. cant boot it in any way whatsoever. so what do you think? its only a week old thats the worst part of it!
I have left it to the store I bought it from for warrantable but its still rooted and have a rom on it. well if its complete dead they cant see if its rooted so thats one good thing.
still want to hear you opinion
sorry for bad english
so, from what I understand, u cant boot into any mode, are u even able to see something on screen? (logo, boot screen, etc.) U can try JIG (it somehow make any samsung device go to download mode). otherwise idk.
Hi guys, I have the same problem with my S7 Edge.
Can anyone help?
OK. So I managed to recover my phone.
The phone was dead because of a software crash(nothing on display, no LED light, power+vol. down for reset not working) and when connected to my PC - nothing (just a connect and after 1 sec. a disconnect sound).
But if I kept the power button pressed without letting go, my PC would detect the phone as exynos8890.
I tried to keep pressing the power+vol. down while connected to PC and I realized that the combo worked because after ~7 seconds the phone would disconnect and reconnect itself (but still as exynos8890).
But I tried a different approach. While connected to the PC I tried to keep on pressing power+vol. down. And I could hear that it disconnected and reconnected. But I did not let go of the buttons. And again a connect and disconnect. And again. And after literally 5 minutes of the buttons kept pressed down without letting go and countless reconnects there was finally a change. The disconnect sound was not heard after the connect sound. At that point I stopeed pressing the buttons and when I looked at the phone I could see that the battery icon appeared. Since the phone was connected to my PC, after 1 min. the battery started charging (it was charged 31%). And after that my phone booted fine.
wow
Hi I have just bought an s7 which turned out to be a Korean G930L but I cant get any response out if it apart from the 2 bottom leds and and the blue one. No response from trying to get into recovery or download mode, basically a black screen though it does vibrate on what i think is start up. It is found by pc and Odin and charges ok, I can tell as I can see properties on pc. But no other response. Is it possible that the previous owner tried to root it using non korean rom or TWRP? Any advice on how to fix either getting TWRP on or screen to light up. I am sorry for being so vague I have pulled it apart and checked all of the connections, screen, motherboard etc but nothing. Or chuck it out or put back on eBay. I tried your idea but it only booted once in that 5 minute period so I tried without it plugged in and rebooted several times but still no screen response.

Some help needed with my beloved Defy+

Hello,
As a newcomer to the forums, I'd like to ask for some help. I tried some of the methods described in several posts, to no avail. The situation is this:
Yesterday, I forgot my Defy+ on my desk and the alarm went of at 21:00 as programmed. It went for about 30 mins after that it was cancelled by default. I switched the wifi on and the phone restarted. In fact it stuck in a restart loop, mostly with the Motorola logo on screen. I took the battery out, kept it for like 30 mins, popped it back in and it went to the recovery console with the exclamation mark and the little droid icon. It stayed there for 30 sec, after that it went dark. Now this happened before so I did not panic and tried the battery swap again.
However, this time the phone is silent. Dead. If I plug it into a PC it gives me the notification sound (like when you pull out a usb drive from your PC) and the battery still gives out 3.7V.
No reaction for pressing the power button or volume up/down or any combination of that.
My question is: Is there a way to revive my beloved phone or is it just a piece of history now?
Additional info: Yes, it was a stock Defy+ with Android 2.3.4.
Any help is appreciated!
Update
Update: When I plug it into a PC with the Volume- button pressed down, a white LED starts to light until I disconnect it. During this if I try to enter bootloader mode, the PC recognises it as an unknown device and immediately prompts me to reconnect it.
Any ideas?

S8 FRP LOCK ; boot loop ; phone not recognized by windows

so I rooted my phone about 6 months ago and never really tried to transfer files to pc. when i finally decided to unroot my phone and back up my device. windows 10 read the phone for 10-20 seconds and then completely disappeared. At this point I tried of 4 different computers we have around the house and the phone wasnt read on any of them. (also tried 4-5 different cables and usb ports) Every time I plugged the phone into the computer it would read it as Charging and not file transfer (possibly hardware issue?).
Anyway I went ahead and backed up my phone using google drive and went on to unrooting the device. As soon as I put into download mode the phone still wasn't read by the PC so i shut down and when i turn it on. it turns on for about 4 seconds saying 'custom binary blocked by frp lock'.
1 whats funny is the phone recognizes its plugged in and when I do plug it in or use it on the wireless charger the phone is constantly trying to turn on, and It gets stuck in an infinite boot loop.
2 also whats funny. the very first time i plugged the phone in it ask for me to allow on the s8 (normally) i did so and it worked for about 20 seconds just enough time for me to find my pictures and beging file transfer.
Then the screen went black due to energy saver. and then it never connected again.
Only thing I am able to do is enter download mode, but from there phone still doesn't read it. and I have to go back to the boot loop
Ive added a video of the boot loop.
just youtube : /watch?v=ncGH-PbvqlQ&feature=youtu.be
Any help would be much appreciated.
If you know anything please let me know
Jon.
Model : SM-G950F
Hi there, I had the FRP lock and took the phone to a authorized Samsung repairer and they reset the FRP for me while I waited there
