Hey guys...
So, I have my Desire Z since about 4 weeks and nothing went wrong with it.
Really NOTHING bad happened, it didn't fall on the floor, didn't fall into water, etc etc.
So this afternoon I unlocked it and suddenly I got a blank grey screen.(worked perfect in the morning) The phone did react to my power up/on button, but I couldn't see what I was doing. Also the touchscreen worked, because I could unlock it (I heard the unlock noise) but I only get a blank grey screen.
I tried Bootloader and Battery pull. Also I took out my SD/SIM/Battery and just blow through the whole phone but nothing want to happen:-(
By the way, my phone is fully rooted and running on Cyanogenmod7 since 5 days. Everything worked perfect until this afternoon...
EDIT:
Looks just like this http://i51.photobucket.com/albums/f368/forthcomingtangent/DSCI1196.jpg
C'mon guys:-(
So is it grey from bootup till it gets to the rom or can you see your boot splash screen and whatnot?

Yes, when I boot it up it's grey, I notice that it's still working because I get the bootup noise. So I can see nothing. But what I noticed is that the grey screen gets a kinda bluegrey screen while the cyanogenmod7 boot animation(the loop)
Sounds like a hardware issue to me, I'd send it in for warranty if I could. Plus, with your screen being the issue I doubt they would check for something like S-off or anything like that
sounds to me like the ribbon cable for the screen has either broken or not placed in its socket properly, does it make a difference when the keyboard is open? try opening it and closing it a few times... watch the screen. otherwise it could be a fault with the screen board or the screen itself
i would try and claim off warrenty or insurance
No it does no difference when the keybaord is open:-(
Problem at the whole thing is, that I have no warranty because I bought it at amazon.com
you either have to see how much htc will charge to repair it, or take it apart yourself and just check the cables... if any are loose then refit them... or buy a new screen, vga board and ribbon cable and fit it
How much would the last option cost?
And how much do you guys think HTC will chare to repair it?
http://cgi.ebay.co.uk/OEM-SLIDE-FLE...944?pt=LH_DefaultDomain_0&hash=item2a10708cb8
something like that if its the ribbon cable.... but that gives you the whole kit
http://cgi.ebay.co.uk/Touch-Screen-...K_Replacement_Parts_Tools&hash=item2a0fd454a5
thats the digitizer but i dont think youll need that but just in case
http://cgi.ebay.co.uk/NEW-GENUINE-H...K_Replacement_Parts_Tools&hash=item2eb3f529d0
thats the screen
but in fairness your better off taking it to a repair shop and getting a price... if you havnt got a warrenty then you dont have to worry about loosing one
Wow thanks, you're really helping me.
So I found a warranty document, since I bought it over amazon.com from another seller(mobilejoker) and it says that they'll repair me my device if it is defect and not my fault. But they also charge 40$ if it's an obvious damage made by myself. Well, I don't know, it wasn't my fault right? I mean it's not like it dropped in water or fell on the floor.
looks to me like its the ribbon cable or the vga board for the screen, as long as you havnt dropped it in liquid, on the ground or opened it up then it cant be your fault... id go with the warrenty first before you open it up
Hit the thanks button please matey
Done
And thanks again for your help.
alrite glad i could help, if you get stuck or if the warrenty doesnt work come back
hey guys I'm having a very similar issue on my phone, I bought a screen on ebay from a USA seller, as well as a flex cable cus both were damaged in my phone. I've got both of those installed and the phone boots up, gives off noises and vibrates like his did, but no video. Backlight lights up, but just black. I've been googling a lot and apparently the grey screen is just a precursor to what I have. Where exactly is the VGA board? is it on the main logic board? does it need a reflow like some laptop chipsets?
Hey guys I just thought I give you a quick update.
So I got my device back, it's working perfect and I didn't have to pay anything for it.
I'm just a bit confused, because my phone now is totally unrooted, and I always thought that root hurts your warranty.
Anyways, thanks for your help!!

Either they gave you a new phone or...
They replaced the screen (or samaged parts) and wiped or perhaps upgraded to newest stock.
Do you still have all your info and apps that were previously on it?
What version of android does it show in about, and which hboot do you have now?

Well it's just like it was when I bought it, 2.2.1, only google apps, had to configure sim again no sms, etc.. But my phone is definitely now new because there are my scratches on the back of the phone.

I didn't quite understand your reply, lol sry, but I did see one big clue....2.2.1. Which means you should have no problems rooting again.

I don't have any problems with rooting again, I was just saying that I was confused that I got my device repaired for free, although they unrooted my phone.
Guys,
I need some help with this. I bought a new S4, a week old, rooted it, unlocked the bootloader and loaded AOKP ROM on it. Today I was applyed a screen protector on it (skinomi). After about an hour the phone started going crazy, opening random apps, screen flickering, basically it was like someone was touching the screen. So I just locked it and kept it away. After a while it got really bad, so I power off the phone. I powered it back on and the screen started flickering again. It turned off and has stopped working since then. I power it on and the buttons light work but the screen is blank. I feel may be I applied too much screen protector liquid and it just messed up things.
Any help? Should I take it to an AT&T store? Will they find out that I have rooted it if the screen doesnt work?
Appreciate any help on this guys.
Flickering could be due to a bad ROM flash. Disabling hardware overlay in Developer Options would be a temporary fix if that were the issue.
But it sounds to me like you got too much water on your phone.
I'd charge the phone overnight (while powered off).
Then I'd pull the battery for a couple minutes.
Put battery back in.
See if you can get into Download mode by pressing Volume Down and Power and Home button at the same time until the phone powers on. If you get ANY video output that is not flickering, then you're good to go and can Odin back to stock.
If you don't get ANY video output, then your phone is hosed.
You can try to warranty it.
If you do get video output but it's flickering while in Download mode, then your phone is still hosed but at least you can now ODIN back to stock before you warranty it.
Thanks for the advice. I applied some heat on it, so that the water evaporates and have kept it on charging now. Hopefully it turns on in the morning.

The problem would have never happened if you would have not flashed a AOKP/AOSP/CM rom but instead flash one
of the many excellent samsung i337 based touchwiz custom roms which are available for the AT&T i337 S4 phone.
You will find many of the features of the samsung S4 touchwiz roms are no where to be found after flashing any of
the AOSP/AOKP/CM type roms.
Glad it's working for you now.

Thank for the advice but I find Touchwiz really ugly. I love the the vanilla android UI and don't care much about the air gestures etc features on touchwiz. Having said that I will try to flash a more stable ROM next time.
Same. Im waiting til the google edition and keylime pie comes out with ir support so I can get a fully working aosp rom

thats the most ridiculous thing i've read in awhile. explain how flashing this broke the users phone and, after following the procedures the user posted, the device suddenly works again without a problem.

Wow, how much water did you put on the phone? You might want to check the visible water damage indicators to see if they turned colors or not. It will be good for you to know incase you ever need to try and repair or replace it through warranty. I'm not sure exactly where thy are located or what color they turn when wet, but you can look it up pretty easy.

Not alot of water, just sprayed some while putting on the screen protector, thats it. I dont see any visible water damage. Screen looks good and no flickering anymore. I will keep an eye on it and if I see any issues I will get it replaced.
Well, if it only flickered while in the operating system, then it was probably ROM related. If it ever flickered OUTSIDE of the operating system, like in recovery, download or while booting, then it was more likely hardware related.
Glad to hear it's working now!
Straight to the point...
About a day before i had dirty flashed xenon 4.4.2 cm based over pa beta 5 and aosp zip for non caf support for cm rom....
After that used for about 1 hours my phone then suddenly got overheating...and when i decided to clean flash the rom and the phone was just about to reboot...The screen went white..And then after a few seconds it starts fading black from edges..and that it...i get nothing else...the phone boots up well i am able to receive calls and sound is also working just no display....when screen is on it just goes white then fades....that is..nothing else...

it gets into the fastboot....but no display...i didnt tried it...but i dont think it will fix it...and if it doesnt fixes then ill loose the recovery...so didnt do that...
I dont think that factory resetting and flashing stock rom will do...coz all that happens in recovery and i can see any think that just a white screen...sometimes faint....must be a display or a motherboard problem....
but when it comes to display it is not broken or got damaged....might be motherboard must be burnt...but if so then why will the cell boot up without issues...
are there any chances of screen damaging due to heat...?coz it has got heated and i got this problem...
And all functions are working even calls sms wifi....everything w/o issue...just no display..
Should think on it..
Can any1 detect where the problem is so that I can fix it...
If you can't buy a new screen assembly to troubleshoot whether that's a possible issue then the only thing I can think of is wiping the phone and flashing the google factory image.
Are you able to download this and flash it through the command line using fastboot?

Hey sturdy I hope your phone carries an Indian warranty !! If yes the best way is to flash back the factory image and get it to your nearest lg centre !!
If u are not covered under warranty lg guys charge around 4.8 k INR for front screen with digitalizer !! You get a screen replacement on eBay for around 2.5 k !! If its the motherboard it can burn a dent in your pocket !!

i dont have warranty....ok i need to detect the problem...so that i can fix it....You can read the previous posts i have written....
Anywayz firsstly i opened up my monster...cleaned the thermal paste..re-applied it....Ok nothing is burnt on motherboard....everything works even usb....my computer is reading the device....just no display thats it...i tried to disconnect the display and see...still everything works no heat up...
so it takes me towards the screen problem....
Now is there any chance to screen plug getting damaged from the motherboard.... there are just two slots i dont think it has any chance of damage...
And also the screen is responsive but not display...i can swipe and receive calls and everything....just no display...
So what is damaged ?
As there are two parts of screen..
This is the exact thing whats happening
After a lot of research...i found that from the three parts which i thought i had problem with is that...lcd digitizer and gpu...
there is no digitizer issue...after my research...now left if lcd might have burnt out or gpu might have burnt out...

I'm really guessing here but like I said before, i'd say restore the factory image from Google to see if there's any software issues at play like a kernel issue.
At least then (if that doesn't fix it) you have the option of either sending in the device to LG for a fix, giving it to a third party repair shop, or buying the screen assembly yourself and replacing it that way.
Like NABENDU1 said you can get one on ebay or other sites, find the tutorials on youtube and you already seem to have the necessary tools so that'd be the cheapest way.
Though i'd say make sure you get the whole assembly to make replacing it easier, or it can get quite fiddly.
If it still doesn't work after that, then it may be a problem with the motherboard which would also need fixing.
Good luck figuring it out though.

The white ring stays even when it's off?
If you're sure you reconnected all the ribbons inside and wiping everything and flashing the factory image didn't solve the issue then it's safe to assume there's a hardware fault somewhere. Unless you or anyone else can think of what else it could be, it looks like it's time to try replacing the screen assembly.
Don't know where you'll be able to find one in India. Ebay might have one, aliexpress might also be worth a look, I saw one on there that ships to India from China for Rs. 4,070.40 / piece with free shipping.
Again good luck!

My Moto X Style has a yellow tint/warm color tone and I'm really confused whether I should send it to service center for repairing or not. I've read it's possible to change the color temperature once you are rooted.
So is there anyone who had yellow tint on their Style but eventually fixed it by calibrating after rooting the device? How you guys did it after root and is warm/yellow tint normal for this phone? Also please help me in deciding whether I should go for a repair or not.
PS: About the yellow tint, I observed it when I compared my friend's Style with mine.
Link for the comparison images:

Edit on 13th Oct, 2016 : Sent my X Style to service center for replacing the display.
Edit on 20th Oct, 2016 : Received my X Style back after a repair but the new display is warm too. I also checked for one more X Style in the service center, it too had a warm color temperature.
This happened to me before I rooted, I factory reset and it went back to normal, try that first.

If it helps I used to notice the yellowing when booting the phone as it uses that bright white background.
Here's a long shot, have you got a screen protector on your phone if so it could be the protector has sun damage, like I said it's a long shot lol
If you're rooted on stock 6.0.0, flash frankenclark 0.14. If you're rooted on stock 6.0.1, flash frankenclark 1.0.
Use any of the suggested kernel manager apps under Installation Instructions to change the calibration. I suggest Kernel Adiutor Mod.

Thank you! Yes I've a screen protector and it's all fine. I mean no sun damage or something. I'm not rooted yet because that will void the warranty if I opt for screen replacement. Isn't there any way to calibrate the display for non rooted users?
Your best sending it in and get it fixed or replaced or take it back to where you got it and get them to give you a replacement.

Here are the comparison of my Style with that of my friend's Style. The difference is mildly visible in pics, maybe because of camera. However, in reality, the other is whitish than mine.

Not yet, couldn't make time because of busy schedule, the service center is far from my house. Maybe I'll visit them in this upcoming week.
I think yours is just like mine. In a way yours actually looks better than your friends because its brighter and colors are more vivid. The best thing is to just use a custom kernel to change the calibration. I wouldn't try to get a replacement if that's the only thing wrong with yours because it most likely will 1) be the same or worse or 2) have a different issue.

Yes my colors look more saturated than his. If you zoom in - in the search bar in chrome, there you'll notice the difference in the white color. I'm just worried if it could be fixed by using custom kernel or not. Ya sometimes I too feel if the replacement would give better results or not.

Hi guys,
We have a bunch(200) of Samsung Galaxy Tab A 10.1 (wifi) running Marshmallow on firmware: MMB29K.T580UEU1APF5.
About 10% of the tablets have been starting to make this trouble after 3-6 months of installation.
Actually it seems pretty random and they are installed in different buildings.
They all have twrp installed, rooted and running xposed framework.
This is a really big concern for us.
I would like to know if anybody had this problem in the past.
I linked a video in attchment.
EDIT: Here is the video of it:
https://www.youtube.com/watch?v=54DCZt9i49M&feature=youtu.be
Thanks in advance
David
Edit guys i uploaded the video on a youtube channel.
We noticed that once this problem occured, sometimes the flicker stops, but there are white lines where white text is present in the interface.
I will upload an other video showing the lines being permanent on the screen after the flicker problem occurs.
We sent 4 of them to samsung and they told us that the motherboard needed to be changed and that the screen/display had no problem.
We did change the board on one of the unit and the problem is still there.
I saw a couple of post reporting this problem, it would be fun to know what is causing this problem.
We are currently suspecting the TWRP recovery, so we reflashed the stock recovery.img on the units that are not having the problem at the moment and hope this will not happen again.
Thanks in advance for your help
Here is the other video I was talking bout:
https://youtu.be/OonoNfWT5ZE
I joined a picture of my tablet when I put it in download mode, the ghosting is pretty intense on that one.
When I swipe the ghosting is less intense because it changes the background color.
We have been using samsung tablets for the last 6 years and this is the first model of tablet that does this.
I think Samsung cheaped out the quality of their screen and when they stay on the same page for a long period of time it seems to ghost very easily on this model.
Here are the tablets we used in the past and had no screen problem yet:
Samsung galaxy Tab 2 10.1 PLS TFT capacitive touchscreen, 16M colors
Samsung galaxy Tab 4 10.1 TFT capacitive touchscreen, 16M colors
Samsung galaxy Tab A 9.7 TFT capacitive touchscreen, 16M colors
Samsung galaxy Tab A 10.1 PLS LCD capacitive touchscreen, 16M colors (The one we are using right now having the problem)
Is it the PLS LCD being cheaper then the other screen we used in the past?
This is the LCD problem, not mainboard. Since you have a bunch of them, it's very easy to verify by swapping mainboard and LCD.
Use a working LCD to verify mainboard.
Use a working mainboard to verify LCD. In your case, swapping a working mainboard and the vertical lines are the same as old mainboard, you know this is a defective LCD. It takes only 5 minutes to swapping mainboard.

Yes this is what we did and in fact the LCD is the problem.
We send 4 of them to Samsung, and they told us it was the mainboard.. which is clearly a lie.
But since the tablets have been rooted they don't want to repair the units on their own charge, which we were awared of.
They were asking 200$ to repair the unit ... which is almost the price of the tablet.
I really think that this lcd is very cheap and that we will need to close the screens every day during a certain period of time to avoid this problem on this generation.
But this should not happen..
Have any advice?
thank you
This whole LCD assembly is only around $61 from AliExpress

Cheaper if you know how to remove the LCD frame and reuse the home button, this one is only around $42

It takes me only under 15 minutes or less to change the LCD assembly. This is OEM part as Samsung orders parts from China, don't worry about fake parts as all Samsung parts are from China

Samsung policy is they don't fix rooted tablet ( Knox count is more the 1 ) unless you agree to change the mainboard . It's a no point to me, flash back the official firmware, root will be gone but the Knox count won't go back to zero.
You should change LCD or setting the screen off after 30 minutes to prevent damages due to permanent ON.
LCD is only around $60, why pay $200 to change it. They properly change both LCD and mainboard. Rooted tablet won't have display issue unless you use custom ROM.
