Phone no longer displays anything? - OnePlus 6T Questions & Answers

So I recently sent in my 6T for repairs with OnePlus support, and told them that it doesn't show anything just black screen. However, the phone shows indications of it working internally by vibrating when a charger is connected. Now I recently (I think) forced it into fastboot mode and it feels like the phone responded. So my actual question is if i can connect the phone to my computer and put it in fastboot, would reinstalling the Rom possibly help?

I don't understand you sent it to repair or you don't?
If your LCD is out of order changing the ROM won't do anything. OnePlus will change your screen I guess, and yes, having a screen broken doesn't prevent the other parts of the phone to work.

I think my Hermes is dead :(

Was working fine this morning, alarm went off etc and checked my mail. Put it into my pocket to read on the bus, got it out and it wouldn't come out of sleep mode. So tried reset with the stylus, no luck, so then pulled the battery and powered on.
All I get now is the green light coming on and staying on and that's it nothing else. I've got Hard-SPL the last released version and Shamanix Ultimate rom which has been fine for the last few months. And yer now this.
I've tried removing the sim card, the storage card and plugging it into windows. It detects something, brings up a network device but then I get nothing after that. I've tried using RUUWrapper to flash another OS rom but it still won't go. (This only happened once)
*Update* Somehow after plugging the usb cable in and holding power and the ok button to get the tri colour screen (even though its staying black) it managed to attempt to flash a new image to my phone. It said it was successful but its still not booting. I'm going to try and reflash the radio and hard spl but any other ideas? I tried looking for mtty to go through that way but no luck.
i had the same problem like you any help oli, pof or any one who could help to come back our hermes??
you sure its even a software problem? it seem to me like a hardware problem, like ur lcd screen is dead or something. i would try a remote control app like mymobiler and see if there's anything there first

Could be a hardware issue but I don't think its the LCD. The lights to indicate bluetooth aren't flashing which I had on by default. Its also not even flashing the green light at this point. It sorta powers on but thats it.
*Update*
After a bit of time the light did start flashing green but no bluetooth. The red and green phone buttons also turned on (Dopod 838 Pro). Its also now appearing to charge off the USB. But still no link in windows. I can ring the phone but nothing happens, it rings in the phone im using but the mobile itself does not.
well in my case my device if i plug it in the charger it charges but no led indication if i turn on the device only the green led turns on but it stays no start of splash etc etc etc only i can put it in bootmode if i flash it dont makes nothing
Well I dropped the phone into the service centre. It is 11 days (taking into account the leap year) outside of warranty. I'm kinda annoyed because the tech there said 3 would normally replace/repair under warranty at 10 days out of warranty.
Either way i've got a quote of $140, they claim its the screen but didnt have a screen in stock to test so i'm waiting for that. Three may still cover it under warranty because its so close to the warranty period and well i've had a few billing issues with them before where they were at fault. Namely the charged my credit card which they had been for over 6 months with no issues and then claimed I had not paid them. It took two weeks and multiple complaints before they accepted my bank statement showing them it was paid.
Still waiting now at almost a week and a half but hopefully its just the screen and they will fix it for me. They were hesitant to but I believe they will cover all of it, at first only offered 50% of the cost which is a bit of a kick in the teeth when its so close to warranty and under statutory warranty it should be covered.
Will keep this updated.
so has anyone figured out a reason/solution to this issue?
Unfortunately no
Once three got the parts in and tested them in my unit they were still unable to get it to boot nor get into some kind of special boot diagnostic mode they use so it was declared a complete board failure and deemed uneconomical to repair.
As it was so close to warranty they are now trying to sort out what they can do, possibly a loyalty upgrade or something similar. I've given them ideas of what phone I would like to get and hopefully they can accommodate me else I will look at chasing the statutory warranty angle.

Htc magic does not boot

Hello,
i have a problem with the phone. When I power it up, the screen lights up but it doesn't show anything else, and the phone does not boot.
I tried pressing home+power to reset the device to factory settings but the Warning icon does not appear.
Any ideas what to try?

You either have a G2 or a Magic. They're two different phones. Sounds like a hardware failure.

It's an HTC magic. So it's a hardware failure? What should i do?
Is there any chance that the bootloader is messed up? If this was the case, the phone should be able to boot in recovery or safe mode, right?
Well you're not giving us a whole lot to go by.
So you power on the phone and the screen lights up but nothing else shows. No splash screen? You can't get it into recovery? You can't get it to the white bootloader screen? If all of this is answered with a NO then it sounds like you have a hardware problem. Did you do anything recently that could have caused this? Dropped it? Flash of a rom, radio, kernel, spl, etc?
Well, it's my friend's phone. As you said there is no splash screen, no white screen and I can't get it to safemode.
He told me that he had problems with the battery, and the phone was without battery for about 2-3 weeks.
Then when he bought a new one, the problems started

ahhh... the plot thickens.
is it an oem battery or generic?
why not try and charge the original battery then go from there
I contact him asking for more information. The original battery failed long time ago. He bought a new one from ebay (i don't know if it was original)
He also said that when he received calls the phone stuck and it rebooted itself. Sometimes it booted successfully, others it didn't
Now it does not boot at all

So its a third party generic battery.

Yes, it is
Well I think that we're all here thinking the same thing. Try a different battery. If that doesn't work then maybe the other battery messed it up. Unlikely but possible.
I have already tried 3 different batteries...

Got the same problem right now, trying to solve it. Was about to post new topic but saw yours. Can you boot your device into bootloader? Mine seems to be able to do that and I see everything but once it shows the Google logo during normal boot or recovery, the screen goes dark and blank.
Very mysterious indeed, never seen this issue before...
Hoping someone can shed some light on this...

Can you remind me of how you did it?
Cause vol up+power\vol down+power won't work for me
What screen have you bought?
Cause I was super anxious about getting original Hydis, now chungwa they now sell everywhere
at first, I would think that I somehow messed uo the cable - but if you are saying, that you are able to boot
mystery!
I guess, we need some experienced service man here

Vol down + power. Though upon further reassembly, it seemed to get worse. Now my screen won't even light up or show anything. Try shining a flashlight on the LCD panel. Do you see anything? If you do, it's likely a bad data cable. In which case, you should find one on eBay.
deltatux
It isn't working at all(
But I can't be 100% sure, cause I've so many change cycles
Buying things on ebay means +1 month of waiting, so I'd prefer to know exactly, will the new cable heal me tablet
Anyway, have you decided, what happened to your screen?

For me since I shone a light and there is something showing underneath and I know that the panel should work since I did see a Google logo and fastboot did properly show up before I reassembled it again 2 times before it completely disappeared, It's likely the data cable, so I repurchased a data cable from eBay.
Have you tried shining a light on to the LCD panel to see if you see anything? If not, it's likely a faulty LCD panel.

[Q] Black screen, no boot, random vibration

Ok, so my Galaxy S4 GT-I9505 won't boot up. Pretty common situation by what i have read on this and other forums so far but mine seems to behave a little different.
Since I've had the device it sometimes just randomly rebooted without any obvious reason but since it only occured once in a few month i did not investigate this any further.
Yesterday it suddenly got really slow when using some normal apps, nothing special (not like a little slow when the cpu is heavily used, but really really slow) it took about one minute for it to close any app and going back to the home screen etc, everything while still recording my actions so when it became unstuck just doing everything i tried in the meantime really fast, then again blocking. So far so good after a reboot that took 5 minutes (even the boot animation appeared extremely slow and fragmented) everything seemed normal.
Until it just freezed while i tried to make a phone call, during which it never dialed but just displaying the dialing animation, although i could switch back to the home screen and back to the "call" i could not end it or cancel it or anything, the phone behaved normal but the call stayed.
Then i tried rebooting it ...
... now it seems to be a brick, nothing will work it won't start up in any mode neither recovery, nor normal, nor download mode nothing.
After a few hours in the charger (i just left it there) suddenly the (untill then black) screen displayed the charging animation, when i tried to boot it then it just went back to a black screen.
After another hour it just started vibrating out of nowhere (and just stopped when i removed the battery).
Thats it, do you have any ideas on that ?
Some other info on the phone :
- rooted stock rom Android 4.4.2 from Vodafone
- tried adb, odin, but no connection to any pc possible at the moment
You have a faulty battery or some other damaged hardware.
Try to see if it boots with an other battery, if that fails then you have hardware damage.
Thanks for your quick reply! I'm going to try a different battery now ...
What ever happened with this? My wife's S4 started doing the exact same thing.
Sent from my HTC One_M8 using XDA Free mobile app
Oh, well I'm sorry I forgot to update the status here.
So I followed the instructions here and bought a new battery, unfortunately the problems didn't disappear.
As the S4 wasn't usable I sent it in to the repair service, which replaced the faulty electronic parts (the Mainboard as I guess). The defect was covered by the warranty in my case.
I don't know how I could help you here, in case the repair might not be covered by your warranty I would try replacing the battery.
Good luck

need urgent help

My screen is half green but only in some screens. I just installed a version of viper trying to get it to work on android 11, it didn't and I removed it. After I rebooted, this happened. Also having no sim card detected if that matters.
Edit: Seems like it's happening in apps now too, not on reboot, like for instance the unlock bootloader warning is normal. Fastboot is also fine, no green. I do see it in the recovery screen where you choose your language though.
Edit2: Reflashed Android 11, installed Magisk on both slots and it's still there when it booted back up
Edit3: I wiped all data and flashed the ROM through fastboot and it got worse. Now the bootloader screen is completely green are are the dots around the boot animation. Do I contact support at this point? Seems like it got worse as time went on..
Anyone ever seen this?
Please help

I can't get edl mode to stick. Once I release the volume buttons after it's plugged in it just reboots. Won't stay in edl so I can't use the msm tool.
Tried both USB 2 and 3 ports, no difference. Could be a driver thing but nothing I've tried has enabled me to update the qc drivers. Can't get the ones built into the phone obviously.
Nothing is backed up.
So now holding volume up and down and then connecting to PC just brings up fastboot every time. Not even recognizing the driver anymore in device manager.
Update....finally got back into the OS after hours of trying things. Ended up flashing all the img files manually and booting back up. Hugeeeeeee issues. See pictures. The phone is going back.

That appears to be a loose flex cable to the screen. Shame it can't just be popped back in. Careful when sending it back as they may look at it and suggest it's been dropped (not saying you have) I've worked in the mobile industry in my younger years and we would certainly query this is it came into our shop.
Hopefully they take it in and deal with it, give you a brew device.
Certainly wouldn't be happening pal.

It's funny you say that something could be loose, I have no idea how. I've only had that replacement device for about 2 months and I've never even tossed it in something other than the bed or a chair, normal handling of a device, let alone dropped it. I hope they deal with it though, between the screen and the extreme overheating I wouldn't doubt that something is fried at this point. There's not a scratch on the device.
Waiting for them to send an email about the repair so I can send it back.

Well the overheating could have been a poor contact with the heatsink (more than likely)
The loose connection if it is that won't be your daily as they should clip in, if this is a refurb then that's probably your answer.
It's a weird one but you've just got to roll the dice mate..
All the best of luck with it..
If you can, try to talk to a tech from OnePlus about it.
Get some clarity if possible.
