Nexus 7 was working fine and then I pulled it out and notices a gray screen. Restarted it and I get a slight blue shadow to the Google and Padlock boot screen. Then it begins to change crazy colors and ends up fading to a gray screen. Can't boot into recovery from fastboot. Help?
Here are some pictures in order of boot.

Wow, I haven't seen or heard of any defect like that in the N7 yet. I would exchange/RMA the device if I were you. It seems like an easily demonstrable problem, there shouldn't be any reason Google/a retailer wouldn't exchange it.

Even with the bootloader unlocked? Or do I need to somehow lock it?

It actually seems as if it is partially just a screen issue. I heard a notification of an email on the N7. I believe it has actually booted up, but the display is stuck. If I tap where the notification bar would be, I heard audio feedback.
UPDATE: I suspected something was loose in display connection because of the type of problem. I knocked pretty hard on the device, and the display kicked back in. Doesn't solve the problem of being unable to boot into recovery, but it seems like it could be a display problem. Suggestion still to just get a replacement? and relock bootloader?

My bad, I skimmed your post and didn't realize you could get into fastboot mode. Try turning off the N7, connecting it to a computer , and getting back to fastboot mode. You should be able to use adb to relock the boot loader. In fact, you should be able to boot into recovery from fastboot since the N7 is connected to a computer.
Good job trouble shooting the display connection! I would still personally recommend exchanging/RMA. You never know when the problem might reappear even if you "fix" it.

Take the back cover off and check the display ribbon cable,and all other connections are tight. They won't be able to tell that the back was removed, unless you ding it up. Might find a loose connection. May just save you the trouble of going through RMA.

Hey guys, I jsu bought a used G1, since I needed a phone because I've started developing apps for android. Anyhow, since I don't have much money I had to buy a used one.
So this one has a (quite big) problem - when the screen is on the keyboard (normal position) the screen turns off. You can see the backlight, but nothing else. When the screen is slid out, it works perfectly fine.
Any idea what the problem may be?

It can be a problem with the ROM also can be a hardware problem.. Try another ROM first and report back.
I tried more than 3 roms, still does the same.
I also filmed how it turns itself off:
http://dl.dropbox.com/u/5608529/vidya/g1.avi
Forgive me for stating the obvious, but have you tried wiping?
Yup, more than once.
At this point, if it was my phone, I'd consider breaking out a screwdriver set and try to see if something came loose or is worn.
Well now it's not working at all.
Not even when the screen is slid out.
And I don't have the required screws to open it... Guess I'll have to buy them somewhere :/
EDIT:
This is weird.. I somehow managed to turn it on, but now it's stuck on a black screen with "Build: " at the bottom of it...
EDIT2:
And now when I rebooted it, only the backlight turns on...
EDIT3:
When I turn it on regularly, the T-Mobile G1 screen appears and then disappears. You can still see the backlight, but nothing else happens.
When I turn it on to recovery mode, the G1 screen appears, then disppaears and then you can see a black screen with "Build: " at the bottom.
EDIT4:
Apparently, when I start it regularly, it does boot into Android, but it's like stuck.. Seems like it's kinda bricked? No idea.
EDIT5:
Is it possible to reinstall the ROM without having access to the recovery menu?

Getting a set of screwdrivers/torx/etc is a good idea. I picked mine up on eBay awhile back. An investment every techy guy should make.
It also sounds like you may want to get acquainted with adb and particularly fastboot. You *should* be able to use fastboot to get a working recovery and then use the recovery to get a rom loaded. This: http://forum.xda-developers.com/showthread.php?t=532719 seems like a decent guide to get you going with what you need if it is in fact a software issue.
Since your experience keeps deteriorating, I'm beginning to wonder if a chip inside is going bad - especially with the odd things like "Build: " showing up. (Let's hope this is not the case!) Nevertheless, I think I'd start with fastboot and go from there. Good luck.
Thanks a lot, ill try it as soon as I get home.

EDIT1:
What the hell? All I did was delete the recovery (didn't even install a new one, kept on saying it's missing the file, even though I did move it using adb push) and now suddenly Android works normally.
EDIT2:
Well now it's stuck again, just like before deleting the recovery...
I'll try to reflash the recovery and then see what happens.
hi guys, this is my 2nd nexus 4 and it already got to lg cervice center less then one month ago.
now i have a problem with the screen.
my phone was on fastboot mode for some time(~45 mins) with usb plugged in, it wasnt hot or warm.
but when i booted into the os i could see some marks of the 2 arrows of the fastboot mode
http://cdn-static.cnet.co.uk/i/c/blg/cat/mobiles/nexus-4-root/fastboot1.jpg (fastbootmode image)
then i restarted in twrp and i still could see(altho it was less, probably because of the buttons not being transparent).
so now the phone is off. do u guys think if i let it off until tomorrow 7am(13hours from now) it will disapear?

nope,if you look the bootloader mode, on top left side there are 2 arrows(one poiting up, other down)after some time on bootloader mode when i started, i still could see a "Ghost" of those arrows on every app etc, even in the recovery... . my phone is turned off, i will turn on in some hours, i hope it fixes by itself
Screen burn. Not sure if that's covered by warranty, you might want to look. If it's not too bad it usually fades over time.
Screenburn is normal on N4.
turned on phone and it was gone.lol i thoght that this didnt happen on lcd screens, on all of my phones the n4 is the 1st to do this...
Hi Guys,
After I "replaced" the screen,it was blank, yet booting and visible to computer,

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.

Phone screen is black, but phone still "works".. Cannot get screen to come back on!
I have no idea what happened, 5 minutes after being in my pocket I pulled it out and the screen was un-responsive.
The notification light is still on, power light, etc. The power button works, I can push and hold and reboot and the two bottom buttons on the phone light up. I was able to "swipe" my password and it vibrated and accepted it, I am getting vibrate notifications too. I just have a black screen and I can't figure out what to do!
I am rooted, but I haven't had any changes to the phone in a few weeks since I had rooted. I tried using http://forum.xda-developers.com/showthread.php?t=2786395 but I cannot figure out how to get the device to show up in the program to use.
I am at a loss on what to do...
No Samsung logo if you remove the battery for 30 seconds, replace it and power on normally?

Nope, no nothing. No logos, no screen flicker, no colors of any sort - just black. The LED goes blue as it boots up, etc, so I know it does power up.. and once it is done I can even swipe my password and it gives the feedback vibrate..
Just in case this was an issue with the root and whatnot I flashed the stock with Odin and I still am getting black screened.
I contacted VZW support last night, and the chat rep told me they would have to just replace the phone. I am guessing this may be a hardware issue.
Yea if there is no logo whatsoever when you first turn it on, it sounds like a hardware issue, not a ROM issue
I forget exactly which logo shows first (S5 I think) that isn't part of the ROM afaik, the Samsung animated logo is the ROM, so if you don't even get the one before the Samsung animation, doesn't sound good
Is it the G900F? If yes, the only thing I can think that might possibly work, is this
http://forum.xda-developers.com/galaxy-s5/general/g900f-debrick-img-lollipop-t3240626

I don't believe it's G9000F... and I am fairly certain now that it isn't a software issue since everything else 'loads', just not my damn screen.. lol.
Thanks for your help though
The reason I posted that link, is, if the bootloader has corrupted, it is possible you won't get any logo at all, and that debrick image basically tricks the phone into using the MicroSD card to boot into download mode from, where you can recover the main storage
It should tell you under the battery which model S5 it is
If the screen doesn't even light up, then it sounds more like hardware
See if this gives you access

It is connector issue.
Either connector is slight loose or if not then need to Change the connector.

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.
