For some reason my screen has stopped working. I press the power button to wake it up and the only thing that comes on are the shortcut buttons. It happened all the sudden this afternoon, and I have charged it sincethento see if that may be the issue. I've taken out the battery 3 times and turned it back on too no avail. When it boots up it make the intro sound but nothing happens on the screen.
It's only 3 months old so it's still covered under the warranty, BUT it's rooted. I need to know is there ANYWAY to revert it back to the stock rom with out the screen so that I can take it back to Sprint. Any help would be great.
Well, they can't see the screen so let them take a look at it. If they fix the screen and see its rooted, no big deal, the phone works.
That is true, I never really thought of that. Let's say they can't fix it. Do you think they would check to see if it's rooted before they replace it, or would they even be able to?
Best bet is to run ruu before you take it in. If they fix it and see its rooted they can be butts and dbr it because of root. One of my Co techs has done it

Ok... The screen does work but it's like the backlight is broken. In the right light and at an angle I can see the screen, and the touch screen works. I have it turned all the way up but nothing. Has anyone ever heard of this happening? The good thing is will be able to revert back now to take it in.
I was trying to downgrade and the phone seemed like it was stuck after hboot to PB31IMG so I pulled the battery now when I try to boot the phone, it vibrates but gets stuck on a black screen. Please help
hold vol down n power at sametime
see if u can get to recovery from hboot, if not I think u mightve screwed yourself

I think the phone is booting up, the buttons at the bottom will light up and the charging light will come on but the screen stays blank.
If you can get into HBoot...try to do a RUU with these instructions: http://forum.xda-developers.com/showthread.php?t=817487
Also...how long did you wait before pulling the battery? And what exact step were you on when you did it?
I waited about five minutes and I cant do ruu because I cant see anything. The screen is black. Thats the step I was on. It said updating do not turn off. After it was done. I let it sit and it didn't do anything so I did a battery pull, I have the phone charging now and the charging light is on.
you probably should have waited at least 30 min...most of this stuff needs time usually if it seems like it's hanging its probably not. did you try getting to hboot yet?
Sent from my ADR6300 using XDA App
I didnt know to wait that long. Also, I tried but I cant get to anything, the phones charging light is on and when I hit the power button, the charging light goes away but the screen stays black. The lights at the button are on also, so it looks like the phone is on but the screen is black.
pull the battery again, then hold vol down and pwr til u get to hboot then let us kno wat happens

Am I missing something? I thought I couldnt get into hboot because I cant see whats going on. The lights at the bottom are lit up and the charging light is on but the screen is black. If the screen is black, I wont know if Im in hboot right?

Here is the fix for the Desire: http://forum.xda-developers.com/showthread.php?t=748498
In theory this fix should work the same for the Incredible, you just need to find the correct Rom.
The problem is that you tried to revert to the stock 2.1 for AMOLED screen phones, and you have a SLCD screen.
Now you basically have to find the SLCD version (not sure if there is one for 2.1?) and blindly get into HBOOT/Recovery and hopefully press the correct buttons to install the SLCD Rom for your phone.
I think this is the rom you want to try flashing (it's the stock 2.2 RUU): http://www.megaupload.com/?d=IH461NS4
Good luck...
nevermind then, try lookin for clockworkmod on crack post in development heard it has the drivers for slcd, you have to rename it pb31img.zip on root of sdcard so you can see recovery

Im trying to listen to what your saying, idk if im doing something wrong. These are the steps im using.
1. I pull the battery.
2. put the battery back in while holding volume down with the power button.
3. it turns back on, i hit up a couple times on the volume
4. the phone turns on, the bottom lights and the charging lights are on.
I can hear the volume go up and down, when i hit menu, home, back, or search the phone vibrates. When I use the volume up and down buttons I can hear the volume going up and down so the phone is on.
I appreciate your help and want this fixed, i may be doing something wrong and sorry if I dont understand but Im not trying to deliberately ignore your advice.

Hi all, the very best noob is posting here
I was enjoying the last AuraxTSense rom (AuraxTSense_8.3_Official_OTA_2.2_FRF91_A2SD +...) installed on 29/01. The display is SLCD. The mobile is branded, so I created-and-used a gold card. Everything was perfect until this morning when I noticed that the display was black and there was no way to come up with an image, or text ... (it's almost black, actually I can see that lights just barely).
Since the installation of the rom was successful, I do not think that the phone is bricked, but It's a supposition. Or not?
As described on forums, I've installed the rom RUU_Bravo_Froyo_HTC_WWE_2.09.405.8_Radio_32.43.00.32U_5.09.00.20_release_140022_signed to try to recover the mobile: I can hear the sound, the cell vibrates, ... but no more as in the beginning.
Any ideas?
Thank you!
would you mind giving some additional info like does the LED turn on, if plugged in to a charger? Does it turn on, if plugged into a computer?
Can you boot into fastboot(vol down + power)?
Did you do anything special before this happened?
How did you flash the ruu(from zip file or via computer)? Did any errors occour?
Also why would you try to flash a ruu, when you had no idea what was wrong or what you were doing? You might just have ruined it more. There is no way to know, but as it was able to run the ruu, apparently nothing was wrong.
Thank you for the reply.

The mobile charges with charger, and USB cable attached on the PC: while charging, the LED is orange.
When off, I can power it up using the power button: the mobile vibrates and after ~25 seconds I can hear the start sound. After ~10 seconds the home+menu+back+src button lights go on for some seconds.
The display, since the start-up vibration, becames barely lighted. While the mobile is powered on, if not used, after some time the display becomes dark and I can resume its lighting pressing the power button.
While the mobile is on, if I plug the USB cable in the PC a new drive appears; it's an empty (0 bytes size) drive - I have no SD in.
Can you boot into fastboot(vol down + power)?

I cannot say this because I cannot see anything, but when I boot with (vol down + power) the mobile does not vibrate.
BTW I can boot with (power+back), as I have used the RUU executable to flash and it worked.

I can say that the behaviour of the mobile after the RUU update is the same of before.

to me that sounds like a hardware (backlight) fault...
But how could you flash the wwe-Ruu? Your handset was branded, wasnt it? Did you use the goldcard to flash the ruu? Remember to flash the original (=branded) ruu before you send it in for repair (if you do so)
RUU_Bravo_Froyo_HTC_WWE_2.09.405.8_Radio_32.43.00.32U_5.09.00.20_release_140022_signed

Yes, I flashed using the goldcard; it was working very well!
The last app I installed was juice defender, the full version, updated two days ago from the market.

I have had this happen twice on Auraxtsense. Both times removing the battery for 30 secs and then replacing and rebooting solved the issue. It eventually came back to life.
In your case it could be a hardware failure ......
Im trying to flash the rom proposed by madman_cro, but today is a bad day: update fails with ERROR 170
Yes AuraxTsense is a great rom, with no doubt! I'm not considering the rom as the origin of the problem, but it would be nice to discover what's wrong in my mobile
In the case it's an hardware problem, I've asked HTC for assitance...

As you say yourself this sounds like a hw error, and such it has nothing to do with auraxtsense, so why the hell should he post it in there.
But it does indeed sound like a hw error. So you will probably have to ask htc, if the prober ruu doesn't solve it. Also slcd brick only happens after flashing a wrong rom/bootloader, so it should not possibly appear out of nowhere.

Why the hell would he do that? Because at that stage a hardware fault was suggested but not confirmed ... so why the hell not?
If it was a problem with the rom like he thought it could be, that would of been a good starting point!
I had the same thing happen with a Blackstone (Touch HD)
Don't know if this is any help, but I had exactly the same thing happen with my old Touch HD. There was a util I found that allowed me to view the phone screen and drive it via my pc through the USB port. This helped in making sure that the only issue was a lack of display, and flashing and returning to stock before sending off for repair. Not too sure if there's something similar for the Desire.
The problem was initially diagnosed as a loose connection within the phone, and the repair center fixed it and sent it back to me. A couple of weeks later exactly the same thing happened. After replacing the mainboard on the second repair visit it was all fixed and worked well (until I fed it too much voltage from a charger, but that's another story). I'd suggest that claiming this experience as your own and requesting a mainboard replacement up front may be the best way to avoid too many service visits.
You'll know that they have replaced the mainboard as they'll issue you with a new IMEI.
selling it on ebay
Thank you all! My experience with support services in Italy and the fact that the phone has been rooted/flashed, have persuaded me to put it on ebay, as is. I still haven't found the solution, so I don't know if it's an hardware problem or something else. In the doubt, I'm selling it as not working.
Hope I will come back with a new desire...

Is it not under warranty??? Its still covered if the changes you made didn't cause the issue ( I think lol)
Sent from my HTC Desire using XDA App
Although most people have said this is a hardware error (I'm inclined to think the same) have you actually tried to hard reset the phone just incase a setting is messed up somewhere and is actually displaying at 0% backlight. Very likely it won't work but is at least worth a shot before you get rid of it on Ebay
trying again
Hi warlordxxx, having the possibility to use another phone (do you remember the 7650? ) I removed the desire from ebay and I'm now trying to best discover what's happened, as I think it's not an hardward problem too.
I'm following the directions posted on the androidiani.it forum: maybe my problem it's just a video driver problem. I will let you know the result of the operations.
Have a nice week.
Basically my HTC Desire HD about 6 months old now has had pretty much nothing go wrong.
But today after using my phone all day it has decided to give up! I have called my phone and it rings and lights up but I still cant slide down the screen to pick up the phone.
The top button works to light up the screen but when I try to slide down the lock screen the phone does not respond.
The phone hasn't frozen because the top button works, I think it is a problem with the screen.
Firstly I would know if anyone understands what I am saying and if anyone else has experienced this problem.
Finally is there any solution to this problem?
Have you tried to force shutdown and restart the phone? Or the lockscreen is not responsive at all in the restart attempt?
8penned from my blazing fast DHD
When you say forced shut down you mean taking the battery out right? Because I've done that soo many times and the result is no different!
Surly it can not only be my phone to have this problem!
I had this issue before, the screen was totally unresponsive. Wiping and flashing rom didn't do the job, even nandriod backup didn't do the job. The solution was to install an ruu.
Sent from my Desire HD using XDA App
Cheers for all the help but I've fixed it now, I left it on charge all night hoping it would spring into life but no this didnt work!
Then I took the sim card out and switched the phone on and the screen became responsive. At the same time I did this I also pushed hard on the back of the screen.
So I dont know whether the force fixed it or taking the sim out did. Personally I think it was removing the sim but I have no idea why that helped.

sigh adb didn't work
Hi , I'm having problems with my Galaxy T999. I have rooted and have not yet installed any kernels/roms. The only thing i did was installed a couple apps from the play store . and wanted to check out the CWM recovery menu and was going to try to installed "hyperX camera mod". First thing i did was shut off the phone . Then pressed on the Volume up+Home+Power button . After doing that my phone didn't turn on or anything , no vibration or anything . I hooked it on with my computer and press the power button and it was able to connect and then disconnected. I am at lost now and can't seem to find any answer . Have looked every where not sure what to do now. Any solution will be much appreciated .
***
It seems to disconnect due to no driver found for QHUSUB_DLOAD .
Without any solutions I'll probably gonna get my phone replace . T_T
Does your phone disconnect immediately, or does it stay connected for a brief amount of time? If it stays connected briefly, try using adb during this period to boot into recovery. The command is "adb reboot recovery" (without the quotes).

Try to remove your battery then plug in charger. See if you can turn on. If you can turn it on, leave it 30 minutes. Then put in the battery.
By the looks of the result the computer gives you when you plug it in, seems it is hard bricked! Are you sure you didn't flash anything from the I9300 section like a rom?

The hyper x camera mod isnt entirely for our phone. I've read that it's flashable to our phone though, so I'm not sure what's going on here. Maybe the OP needs to link where he got the mod. Ih and stay away from the intl version all together.

Yup its a paperweight. The Intl version has the system partition in a different place. So you borked an important one.
Only thing that's throwing me off is that the OP suggests he didn't actually get around to flashing the mod.

SGS3 T999v wont start up.
My sgs3 t999v would turn off by itself every other time I hit the lock button.
like I would be txting and then if I hit the lock button it would turn off.
So I though a factory reset would fix the problem. (volume up + home).
after the reset it still kept turning off randomly.
and now I cant even get it to the normal interface. or get in to the manual reset mode.
Device was previously jail broken, however was returned back to stock and was working fine for 3 months.
I had my otterbox on for every fall my phone had, so I dont think it would be a hardware issue.
the phone was running 4.1.1 I believe.
stock rom.
help please! :C

Can you get download mode? (Volume down, HOME and power)
Even though you have a case on it, it sounds like it was probably damaged by one of the falls. Most cases as far as I'm aware mostly protect the display. The shock from impact can still damage internal components, even with a case built with this in mind.

Hey thanks for replying!
I drained the battery and got a new charge in it and managed to get it booted up
however now the problem of the lock button is still here.
like if i use it to lock my screen it just turns off on me, and it takes multiple times for me to get the phone up and running again.
you could see if you could find a widget or widgets that will basically put a button on your screen that can power off, enable lock screen, reboot recovery/download, etc.
Then just use the HOME button to turn the screen back on.
It sounds to me like a hardware problem, but if you can flash another Rom and do a full wipe/factory reset you'll know for sure.
I hope this helps. Not sure what else you can do besides getting it repaired or replaced unfortunately.
Maybe someone else will have a better idea though.
