Urgent help needed

Well it seems my Play has finally died.
Woke up this morning and my touchscreen wouldnt respond so I reflashed the ROM Im using (MIUI v4).
Now, for some reason, it wont make it past CWM no matter what kernel I flash.
So I used Flashtool to go back to a stock ftf and it freezes at the SE logo. However, when connected with PC Companion it gets to the lockscreen but the touchscreen wont work :S
Im at a loss completely :S
Any help would be great

Woo man.. That sounds srious. Its like the phne touchscreen has been disable. Did u try flashing a kernel with full touch recovery n see if its touch-able?? Just a suggestion. Its really weird how that happen, really. It shouldn't matter if u plug ur phone to pc or not. If the screen boot it should respon with any touch u make. Weird...

I tried the CWM with touch support and it doesnt respond at all. When I flash a ROM it wont make it past CWM so it seems like Ive got 2 problems. Well, if I flash a stock ftf file it sticks at the first Sony Ericsson logo as well so flashing back to stock isnt a solution either
EDIT: I appear to have life CM9 has booted to the main splash screen. However, touch input is still gone

Meaning the touchscreen is completely dead or it dosen't boot up the system completely?? This is hard. If the screen is touch-able u obviously wont hav any problem. Did u try any othert .ftf besides the 1 u already hav?? Just curious...

No man....don't say that. You have been a big help here, especially to me. I wonder what you did to that screen and if it happened from a rom flash or what.

I flashed an MIUI ICS rom and the following morning it was locked up. Now certain kernels wont go past CWM.
FXP kernels seem to work for me though but the touchscreen doesnt work. Some of the stock firmwares wont even boot but even if they do, the touchscreen doesnt work. Ive wiped data/cache/dalvik so many times but I havent a clue whats happened :S
Im still gonna stick around the Play section though
This has been the only phone issue thats ever had me stumped completely

Did u did a factory reset also before flashing anything?

Can you enter the service menu by dialing *#*#7378423#*#* in phone dialer?? Then you can test the touchscreen, hard keys, proximity, ALS, and almost all other functions. I'm not sure if its the same numbers for all versions of Play or just AT&T's version. If not google service menu+android or something. Or maybe its something that can fixed with computer by the guys who unlock fix Sony phones.(Jinx13 & alejandrissimo-*probably misspelled)

Sure. U can test the touchscreen on that menu. If u can get to it. The code r the same for all xperia phone, i guess.

Got to that menu and its still not responding to touch.
Sold the phone for scrap today. I had no warranty due to unlocking the bootloader via the Sony Unlock site so sending it for repair was out of the question. Moving on to HTC at the weekend. Gonna get the Explorer I think it was

[Q] Soft Brick

Rooted my wildfire S then installed Clockmod Recovery but saw only a back screen, so searched the internet and tried [email protected] got the output on my Laptop screen and flashed a custom rom. The phone turns ON and the rom is working too but there is no output on my phone screen, using [email protected] I can see the rom working on my laptop.
So basically I can't see output on my phone's screen. I can load into bootloader.

No more problems, just only that. I read some where to make your phone alive once again, one has to flash a new rom. I was tired so I did a Nand Restore. It's back the way it was.

Could it be a broken LCD?

Sounds like a hard ware problem, do you have a warranty on the phone?

[Q] HELP! My Xperia Play Died!

Help! I think My Xperia Play died on me! Here's what happened. It may be a long post but PLEASE bear with me. I really need your help guys! My phone was just lying around on my desk and I decided to use it and was surprised because it won't unlock. So i thought that my home button was just malfunctioning and tried to slide it's game pad as it unlocks the phone by itself but still no respond. So I thought it turned off by itself and when I tried to turn it on, it won't turn on at all because there's no short vibration. Usually when we turn on our device, there's a short vibration right? So I removed the battery, placed it back again and turned on my phone and at last there's the short vibration. But after a while I noticed that the boot splash hadn't appeared yet. I waited for a couple of minutes but still nothing happens. When I turned it on again there's the short vibration and that's it. So I searched for solutions here on XDA and on the web and I tried almost all of it. I flashed it back to it's stock firmware using Flashtool and still the same. I tried using PC Companion and Sony Ericsson Update Service but still to no avail. I also relocked it's bootloader and reflashed everything again but nothing works. So I gave up because I thought it might be a hardware issue but I didn't drop my phone or anything so i don't know what went wrong.
Then the following day I decided to check on my phone again and to my surprise it's back to normal and I was really glad about it. So I didn't flash any custom ROM and Kernels because I'm afraid that it might screw everything again. I just rooted it and completely debloated it and installed init.d support for stock kernel. I flashed CrossBreeder and RTMixManager and modified it's systemui for quick panel and battery % mod. I also flashed custom boot animation and that's it. I was happy about my phone because it seems all is well.
But yesterday when I was about to use my phone, the same thing happened again! I tried to redo everything I did all over again but still nothing! I can still use it in flashmode and fastboot though. I also tried entering CWM Recovery. After I turned on my phone I spam pressed volume down and blue LED showed up with the vibration if you enter recovery mode but there's no display. Can anyone tell me what's the problem? It might be the flex cable or the digitizer but I don't know. Has anyone encountered the same situation as mine? Please help me! I don't know what's wrong with my phone!
P.S. I can't send it to Sony Centre as my warranty is already expired. My only option is buying a new Xperia Play. Because I browsed for replacement parts on the web and they don't ship it directly to my country and it costs too much if I have it ship to me indirectly.

You have a hardware failure, I see that right now is very common, you will need to replace the automatic light sensor, to get it working, or if you don't want replace it, you will have to switch onto JB, because it has ALS disabled by default.

[Q] Screen Blacks Out - Should I send in to get fixed?

Just yesterday, my phone was working fine and then all of a sudden, my phone's screen turns completely black. I have the T-Mobile version of the Samsung Galaxy S4 with Stock Rom and the factory kernel. I did root my phone and tried to reset the phone by trying to boot up the recovery. It doesn't give me the screen. There is also no Samsung Logo when I boot the phone but a screen with green dots all over. Then, it is on and I can guess my password and such so the touch screen is functional. The LED lights up and the soft keys light up as well. The sound works perfectly fine. So I assume something happened to the LCD screen? There are no cracks or what not.
Since it is rooted, I cannot just send my phone in for repair as the warranty is voided and I cannot uninstall anything or unroot my phone because I cannot see where all my icons are and what not. Any suggestions on what I can do or try? I got it not too long ago too which is a bit disheartening.

Dame thing happened to my gs3, I did reset it back to stock through odin and sent it in. They told me after I sent it in that it had damage to it that was my dually like dropping it or something. No that wasnt the case, the screen just slowly fizzled out. Pain in the ass
Sent from my SGH-M919 using xda app-developers app

I actually don't know how to do a reset via odin. I flashed it and followed instructions/research but since I can't see what is on the screen nor boot it up to download mode or anything... I don't know exactly what to do. Well I think I can boot it up to download mode again. I don't think it will be a problem. I just can't do triangle away after that though after that.
In addition, I would still have root tools installed so wouldn't that give it away that it was rooted? Thus, gahhh this is annoying =( Sorry for ranting... Just very frustrated (like many phone users on here I'm sure).
Edit
I have it on stock rom though... I just need to unroot it... though I cannot see my screen to do anything about it =/

If you have USB Debugging enabled you can used adb to remove root, I believe.

Odin back to stock should do it. Especially, with a busted screen.

However, my issue isn't a broken screen. The screen itself appears to be fine and same with the digitizer. I don't see how flashing the stock rom will help. In addition, I don't think I can find my way around especially when the screen is all black. I may be able to because I have clockworkmod recovery on there. Just can't see any of the menus or anything.

flashing back to odin uses the phones download mode you dont need a custom recovery you just download the right files and put them in PDA in odin and flash them to your phone while its in download mode

Well the next issue is, it refuses to go into recovery mode or download mode. All I get when I try the button combination is a screen filled with tiny green dots.

do what he does in the video even though your phone doesnt show anything on the screen it probably still works so you can try this

Hyper Gamer rom, screen won't wake.

I'm having this strange issue with the Rom in the following thread; http://forum.xda-developers.com/showthread.php?t=2578972.
Sometimes when I press the power button the screen doesn't wake. This doesn't happen all the time and I've been trying to work out a pattern without success. If I pull the battery and try to boot the phone, it will vibrate to show that it reached the kernel logo but again the screen isn't on so you don't see it.
The only way I've found to fix it is by removing the batter for a while, clearing some sort of temp memory. Then the phone boots as normal and i can use correct.
No other issues and I wondered if anyone had any ideas on what this could be. I would post in the development thread but I don't have the permissions. Any help much appreciated.

Hi Jure220, thanks for the reply. I'm using the 480p version of the one you recommended in the ROM thread here; http://forum.xda-developers.com/showthread.php?t=1804003.
I'm not able to try adb devices right now, but will do later. It's like the phone is still running but just the screen won't turn on. Sometimes I can get it to come alive with by opening the slider. When booting with the problem, I get one vibrate to show that the power has been pressed, then another for the kernal logo (used to indicate going into the recovery menu). It's very strange, I will get back to you on the adb devices but is there any other details I could get you?
Cheers for the help.

If its posible run adb logcat when the screen still works and keep it connected until the black screen apears and post the log in a txt file. But it isnt necessary. But if you reflash the rom it shuld work fine. And if it dosent try the new update I just released

Yes I did notice that you had posted v1.3, will give that a try. I was a bit confused as to why the ROM would affect the screen on boot, but this is me assuming that it is something to do with the ROM at all.
Out of interest, did I need to use any specific settings when formatting /system ready for the ROM? I did a full wipe and fresh Kernal install at the time so had to format it.

When you flash the rom /system will be formated automaticly, and I also doubt it is a rom issue I think something went wrong while flashing...

Hi Jure2020, so I just flashed the ROM again with v1.3, booted fine after flashing. Powered off and then black screen again. I think that it must be a Kernel issue, do you have any other recommendations for Kernels compatible with your ROM?
I tried adb devices btw, all I got was the follwing;
C:\Development\Android SDK\platform-tools>adb devices
List of devices attached
CB5A1E0AJ2 device

Yeah I will try re-flashing a new kernel this evening. Will try this one; http://forum.xda-developers.com/showthread.php?t=2167766.
No honestly, just one time I noticed it didn't wake the screen. Then it got a bit more regular, now it's pretty much every time the phone is left idle for a while, the screen just won't come on. The phone is active, I can 'unlock' it by swiping; I get the haptic feedback and hear the unlock noise. The phone is running, just the screen is off. I even thought it could be a CPU clocking issue, so used SetCPU to force the minimum speed up for resumption and no luck their either.
I have been thinking that it could be a hardware issue, my phone is kinda old now, but the thing is once the phone is on, it's on. I've gamed on it for a good hour or two with no problems, then pressed power to sleep and immediately haven't been able to turn it back on again. It's just very strange, thanks for the help though.

Hi JimmyDeemo,
I think your problem is flex cable related. I've also experience this before. After I replaced the damaged flex cable, my phone just work fine....:victory:
